RESUMO

The collection of adults and larvae sampled at the same site on Sicily and the absence of confusing species at the sampling location enabled a description of the hitherto unknown larva of Rhyacophila hartigi Malicky 1971 (Trichoptera: Rhyacophilidae). We present information on the morphology of the larva and illustrate the most important diagnostic features. This dataset is included in a discriminatory matrix of the ten other Rhyacophila larvae with tufted multifilament gills of Italy described so far. Species can be separated by coloration patterns of head and pronotum, and by anal claw morphology; however, separation of the R. dorsalis-palmeni-simulatrix-vulgaris species quartet is not yet possible. Rhyacophila hartigi is restricted to the southern Apennine Peninsula and the island of Sicily (Cianficconi et al. 2008).

RESUMO

This synoptic paper is intended to summarize and supplement the information available on the larvae of Thremma McLachlan 1876 in Europe. We present information on the morphology of the larvae and illustrate the most important diagnostic features. This information is used for the construction of a comprehensive discriminatory matrix for the four European species of family Thremmatidae Martynov 1935 known in the larval stage so far. In the context of this matrix, larvae can be easily diagnosed by the shape of mesonotal sclerites, foretrochantins, forefemora and ventral sclerites on abdominal segment I, by head coloration patterns, by case morphology, and by distribution. In addition, ecological characteristics and distributions of the European taxa are briefly discussed.

RESUMO

Limnephilus minos Malicky 1970 is a micro-endemic caddisfly restricted to the Greek island of Crete. Mesophylax impunctatus aduncus (Navás 1923) is known from Turkey and the southern Balkan peninsula; Greek records range from islands close to the mainland and Skiros to the northern mainland, and Attica. This paper describes the previously unknown larvae of both taxa. Information on the morphology of the 5th larval instar of each taxon is given, and the most important diagnostic characters are illustrated. A discriminatory matrix for the Greek limnephilid larvae with multifilament gills is also provided. In the context of existing identification keys, the larva of L. minos belongs to the group of Limnephilini larvae where face setae are lacking on the mid- and/or hind femora; the species keys together with L. auricula Curtis 1834 and can be separated from the latter species by setae present between the primary setae on the distal section of mid- and hind trochanters. In contrast, face setae are present on the mid- and/or hind femora in M. impunctatus aduncus. Its larva can be easily identified by the fact that 3 or more ventral-edge setae are present on the midfemur, by setae present on both sides of the anal slit, and by its grazer-type mandible lacking terminal teeth.

RESUMO

Larvae of three leptocerid caddisfly subspecies described in the present paper were sampled in Greece and the North Aegean island of Gökceada (Turkey). Information on the morphology of the final larval instar of each is given and the most important diagnostic features are illustrated. The subspecies are integrated into a synoptic discriminatory matrix including the currently known larvae of Greek species of genus Athripsodes. The species can be easily separated by head coloration; the morphology of the ventral apotome; setal and spinal patterns on the metadorsum, foretibiae, and anal prolegs; and by distribution. With respect to distribution, Athripsodes longispinosus longispinosus is known from Bulgaria, the Caucasus area, Turkey, the northern Greek mainland, and the Greek islands of Thasos, Lesbos, Andros, Ikaria, Naxos, and Rhodes. Athripsodes longispinosus paleochora is an endemic of the Greek island of Crete, and A. bilineatus aegeus has been recorded from the Peloponnese; the Greek islands of Euboea, Skiathos, Kithira, Andros; and Turkey.

RESUMO

This paper describes the previously unknown larva of Plectrocnemia renetta Malicky 1975. Information on the morphology of the final instar larva is given and the most important diagnostic features are illustrated. A preliminary discriminatory matrix for the Greek larvae of Plectrocnemia Stephens 1836 is also provided. Plectrocnemia renetta and P. conspersa conspersa (Curtis 1834) belong to the group where the inner and outer dorsal secondary setae on abdominal segment IX are strongly different in length. These two species can be separated from each other by the arrangement of muscle attachment spots on the head capsule, number and length of setae on abdominal sternum IX, and by distribution patterns. With respect to zoogeography, Plectrocnemia renetta has been reported from Cyprus, Turkey, and from the Greek islands of Ikaria and Samos.

RESUMO

Rhyacophila aphrodite Malicky 1975 is a micro-endemic species of Cyprus and the only rhyacophilid caddisfly recorded on this island. This paper describes the previously unknown larva of this species. Information on the morphology of the final larval instar is given, and the most important diagnostic features are illustrated. In the context of existing Rhyacophilidae identification keys, the larva of R. aphrodite belongs to the group fitted with one single-filament gill on each side of the meso- and metathoraces and one four-filament gill on each side of abdominal segments I to VIII. In addition, a sword process is present on each anal proleg. The distal anal claw tooth is perpendicular to the longitudinal axis of the anal claw and shorter than half of the anal claw width at the distal tooth insertion.

RESUMO

Based on adults, mature pupae, and larvae sampled at the same sites on mainland Greece and on the Greek islands of Kerkyra (Corfu) and Crete, the previously unknown larval stages of Rhyacophila tsurakiana Malicky 1984, R. gudrunae Malicky 1972, and R. biegelmeieri Malicky 1984 could be associated and identified. This material enabled us to describe and illustrate the final instar larvae of these three species, and to extract reliable diagnostic characters updating the existing larval key to the Greek species of genus Rhyacophila Stephens 1836 (Karaouzas et.al. 2015). In the context of this key, R. tsurakiana (together with R. tristis Pictet 1834 and R. obtusa Klapálek 1894) lacks abdominal gills; the three species can be separated by the shape of the dorsal sclerite of abdominal segment IX and by anal proleg morphology. Rhyacophila gudrunae is the only Greek species so far where larvae are fitted with one four-filament gill on each body side of the abdomen. Finally, R. biegelmeieri has one tufted multifilament gill on each body side and can be separated from four other species sharing this gill morphology by coloration patterns and head widths; however, separation from R. nubila Zetterstedt 1840 and R. palmeni McLachlan 1879 is not yet possible. Rhyacophila tsurakiana and R. biegelmeieri are large-scale endemic caddisfly species of European Ecoregion 6 (Hellenic Western Balkan), whereas R. gudrunae is a micro-endemic species of this region and restricted to the island of Crete (Malicky 2005b; Graf et al. 2008).

RESUMO

This paper gives a description of the hitherto unknown larva of Halesus nurag Malicky 1974 (Trichoptera: Limnephilidae). Information on the morphology of the larva is given, and the most important diagnostic features are figured. In the context of the European Halesus species, the larva of H. nurag is morphologically close to H. appenninus Moretti Spinelli Batta 1979, H. digitatus (Schrank 1781), H. radiatus (Curtis 1834), and H. tessellatus (Rambur 1842). This new morphological dataset was used for providing a key to the Sardinian limnephilid larvae. In this context, H. nurag can be separated from the other Sardinian species with single-filament gills described so far by chaetotaxonomical characters, mandible morphology, and details of the lateral protuberance of abdominal segment I.

RESUMO

The hitherto unknown larva of Apatania theischingerorum Malicky 1981 is described, based on the association with adult females using sequence data from the mitochondrial cytochrome c oxidase region. Genetic data confirmed the distinct status of this taxon within the parthenogenetic Apatania muliebris complex (Schmid 1954). We provide information on the morphology of the larva and figure the most important diagnostic features. Apatania theischingerorum is morphologically close to A. fimbriata (Pictet 1834). In the context of the Apataniidae key of Waringer et al. (2015), the species pair can be separated by pleural setation patterns on abdominal segment I and by their distribution ranges in Europe: A. fimbriata is known from the Alps, the western and central highlands, the western plains, the Hungarian lowlands and the Carpathians, whereas A. theischingerorum has been recorded exclusively on the Iberian peninsula.

RESUMO

This paper describes the previously unknown larva of Apatania cypria Tjeder 1952. Species association was enabled by the fact that both larval and adult specimens were collected at the same location and that A. cypria is the only apataniid species known from this island (Malicky 2005). Information on the morphology of the larva is given, and the most important diagnostic features are discussed, including those distinguishing it from the closely similar A. subtilis Martynov 1909 and A. theischingerorum Malicky 1981. In the context of the Apataniidae key of Waringer et al. (2015), the three species can be separated by gill arrangement, the number of setae on the metanotal lateral sclerite, and by their distribution patterns: A. cypria is a Levantine species of Cyprus and Lebanon, whereas A. subtilis is restricted to the Caucasus area and A. theischingerorum is a large-scale endemic of the Iberian peninsula.

RESUMO

Caddisfly samples collected from Corsica, Sardinia, and the Italian mainland included the adults of Sericostoma sasbaddes Malicky 2010, S. maclachlanianum Costa 1884, S. clypeatum Hagen 1864, and S. siculum McLachlan 1876. This material, combined with the unique distribution patterns of the four species, enabled the association of the final instar Sericostoma larvae collected at the same locations. Larvae of the two species from Sardinia (S. sasbaddes, S. maclachlanianum) can be separated by the number of bifurcate setae on each pleuron VIII. The two other species are geographically well separated: S. clypeatum is the only Sericostoma species present in Corsica, whereas S. siculum is confined to the Southern Italian Provinces including Sicily. Morphological characters from the larval descriptions have been used for constructing a preliminary larval key to the hitherto known Sericostomatidae species from European Ecoregion 3 (Italy, Corsica, and Malta).

RESUMO

This contribution describes the previously unknown larva of Adicella cremisa Malicky 1972. Information on the morphology of the 5th larval instar is given and the important diagnostic features are highlighted on micrographs. Within the genus Adicella the hitherto known larvae differ in color patterns of the head capsule, the morphology of the posterior process of abdominal segment I, and in setation patterns on the metanotum, metasternum, abdominal segment IX, and anal prolegs. With respect to zoogeography, A. filicornis and A. reducta are widespread throughout Europe whereas A. cremisa is restricted to European Ecoregions 3 (Italian Mainland), 5 (Dinaric Western Balkan: Slovenia, Croatia), 9 (Central Highlands: Austria) and 11 (Hungarian Plains; Vienna). Based on mandible morphology, A. cremisa is likely a collector-gatherer and shredder.

RESUMO

This paper describes the previously unknown larvae of three Beraeidae species restricted to Greece: Beraeamyia aphyrte Malicky 1972, Bm. kutsaftikii Malicky 1975, and Bm. matsakii Malicky 1980 (Trichoptera: Beraeidae). Information on the morphology of the larvae is given, and the most important diagnostic features are illustrated. The trio of species can be easily separated by an angle present in the dorsal outline of the pronotal carina in Bm. kutsaftikii whereas this dorsal outline is straight in the remaining two species. Finally, the dorsal ridge of the pronotal carina touches the dorsal ecdysial line in Bm. matsakii, but fades far away from the ecdysial line in Bm. aphyrte. With respect to distribution, Bm. kutsaftikii is restricted to the mountains of Central Greece, the Peloponnesos, and the island of Euboea; Bm. matsakii is an endemic of the Ochi mountains in the southern part of Euboea and the island of Andros; and Bm. aphyrte is an endemic of the island of Crete. The species are integrated in a synoptic discriminatory matrix including the currently known Greek Beraeidae larvae. In addition, ecological information on the species is provided.

RESUMO

This paper gives a description of the hitherto unknown or poorly known larvae of Rhyacophila rougemonti McLachlan 1880, R. trifasciata Mosely 1930, R. pallida Mosely 1930, and R. tarda Giudicelli 1968 (Trichoptera: Rhyacophilidae). Information on the morphology of the larvae is provided, and the most important diagnostic features are figured. This dataset is included in a discriminatory matrix of the Rhyacophila larvae with tetrafilament (i.e., four-filament) abdominal gills of Italy and Corsica described so far; only the species pair Rhyacophila pallida / R. tarda in Corsica remains unresolved. Larvae can be separated by the number of metathoracic gill filaments and anal proleg morphology, and by distribution patterns. Endemism is high in the species quartet described in the present paper: Rhyacophila pallida and R. trifasciata are Sardo-Corsican endemic species, R. tarda is restricted to Corsica, and R. rougemonti is a South-Apennine endemic species.

RESUMO

In this paper, we present a description of the previously unknown larva of Agapetus episkopi Malicky 1972 (Trichoptera: Glossosomatidae). Information on the morphology of the larvae is given and the most important diagnostic features are photographed. As a species of subfamily Agapetinae Martynov 1913, A. episkopi larvae belong to the group of species with sclerites present on the pro-, meso-, and metanota. Because lateral setae on abdominal segment III are lacking and the larval case lacks a sand collar at its base, A. episkopi keys with Agapetus laniger Pictet 1834 and Agapetus delicatulus McLachlan 1884. Within this trio, each of the latter two species can be easily separated from A. episkopi by the coloration pattern of their frontoclypeus, where a pale central area is present, and by the presence of only one lateral seta on each side of abdominal segment I. With respect to distribution, A. episkopi has been recorded from European Ecoregion 6 (= Hellenic western Balkan region) and Asia Minor. In addition, ecological characteristics are briefly discussed, and a key to the known glossosomatid larvae of European Ecoregion 6 is included.

RESUMO

This paper describes the previously unknown larvae of Sericostoma bergeri and S. herakles (Trichoptera: Sericostomatidae) restricted to European Ecoregion 6 (= Hellenic western Balkan). Information on the morphology of the larvae is given, and the most important diagnostic features are illustrated. Sericostoma bergeri and S. herakles can be easily separated from known sericostomatid larvae of Ecoregion 6 (Schizopelex huettingeri, Oecismus monedula, Sericostoma flavicorne and S. personatum) by the shape of the pronotum, presence or lack of a comma-like marking on the lateral protuberance, by the number of setae on abdominal dorsum IX, and by distribution patterns. With respect to the latter, S. bergeri is a micro-endemic of the Greek Islands of Euboea and Andros whereas S. herakles is an endemic of the Peloponnese. The species are integrated in a dichotomous key including the currently known Sericostomatidae larvae of the Hellenic western Balkan. In addition, ecological information on the two species is provided.

RESUMO

Adicella syriaca is a leptocerid caddisfly distributed throughout the Balkan Peninsula, the Carpathians, the Hungarian Lowlands, the Pontic Province, and the Caucasus. This paper describes the previously unknown larva of this species, based on material from the Greek island of Corfu. Information on the morphology of the fifth larval instar is given, and the most important diagnostic features are illustrated. A key to the known larvae of the European species of Adicella McLachlan, 1877 is provided. In the context of existing identification keys, the larva of Adicella syriaca Ulmer, 1907 keys together with Adicella cremisa Malicky, 1972, but the species pair can be easily separated by the number of setae on the pro- and mesonotum, and setation patterns on abdominal dorsum IX.

RESUMO

BACKGROUND: Taxonomy offers precise species identification and delimitation and thus provides basic information for biological research, e.g. through assessment of species richness. The importance of molecular taxonomy, i.e., the identification and delimitation of taxa based on molecular markers, has increased in the past decade. Recently developed exploratory tools now allow estimating species-level diversity in multi-locus molecular datasets. RESULTS: Here we use molecular species delimitation tools that either quantify differences in intra- and interspecific variability of loci, or divergence times within and between species, or perform coalescent species tree inference to estimate species-level entities in molecular genetic datasets. We benchmark results from these methods against 14 morphologically readily differentiable species of a well-defined subgroup of the diverse Drusinae subfamily (Trichoptera, Limnephilidae). Using a 3798 bp (6 loci) molecular data set we aim to corroborate a geographically isolated new species by integrating comparative morphological studies and molecular taxonomy. CONCLUSIONS: Our results indicate that only multi-locus species delimitation provides taxonomically relevant information. The data further corroborate the new species Drusus zivici sp. nov. We provide differential diagnostic characters and describe the male, female and larva of this new species and discuss diversity patterns of Drusinae in the Balkans. We further discuss potential and significance of molecular species delimitation. Finally we argue that enhancing collaborative integrative taxonomy will accelerate assessment of global diversity and completion of reference libraries for applied fields, e.g., conservation and biomonitoring.

RESUMO

BACKGROUND: Vector-pathogen dynamics are controlled by fluctuations of potential vector communities, such as the Culicidae. Assessment of mosquito community diversity and, in particular, identification of environmental parameters shaping these communities is therefore of key importance for the design of adequate surveillance approaches. In this study, we assess effects of climatic parameters and habitat structure on mosquito communities in eastern Austria to deliver these highly relevant baseline data. METHODS: Female mosquitoes were sampled twice a month from April to October 2014 and 2015 at 35 permanent and 23 non-permanent trapping sites using carbon dioxide-baited traps. Differences in spatial and seasonal abundance patterns of Culicidae taxa were identified using likelihood ratio tests; possible effects of environmental parameters on seasonal and spatial mosquito distribution were analysed using multivariate statistical methods. We assessed community responses to environmental parameters based on 14-day-average values that affect ontogenesis. RESULTS: Altogether 29,734 female mosquitoes were collected, and 21 of 42 native as well as two of four non-native mosquito species were reconfirmed in eastern Austria. Statistical analyses revealed significant differences in mosquito abundance between sampling years and provinces. Incidence and abundance patterns were found to be linked to 14-day mean sunshine duration, humidity, water-level maxima and the amount of precipitation. However, land cover classes were found to be the most important factor, effectively assigning both indigenous and non-native mosquito species to various communities, which responded differentially to environmental variables. CONCLUSIONS: These findings thus underline the significance of non-climatic variables for future mosquito prediction models and the necessity to consider these in mosquito surveillance programmes.
