RESUMO

Males of four new species of caddisflies from Kampong Speu and Siem Reap provinces, Cambodia [Psychomyia kimcheangi n. sp. (Psychomyiidae), Macrostemum siemreapensis n. sp. (Hydropsychidae), Leptocerus angkorwatensis n. sp. (Leptoceridae), and Trichosetodes kampongspeuensis n. sp. (Leptoceridae)] are described and illustrated. Psychomyia kimcheangi n. sp. can be distinguished from other species by characters of the inferior appendages. The main body of each inferior appendage has two branches that are separated near its base but are parallel and close together until the end. In Macrostemum siemreapensis n. sp. the dorsal tip of the phallus has no curved hooklet but instead a knot-like protruding structure in ventral view and looped-like structure in dorsal view. Leptocerus angkorwatensis n. sp. can be distinguished from others by the characters of long needled-like preanal appendages. Trichosetodes kampongspeuensis is distinguished from others by the characters of segment IX in ventral view, which is asymmetrical, and inferior appendages that are not divided and asymmetrical.

RESUMO

Males of four new species of caddisflies, Polyplectropus hofmaierae n. sp. (Polycentropodidae), Eoneureclipsis chinachotiae n. sp. (Psychomyiidae), Hydropsyche khaonanensis n. sp. (Hydropsychidae), and Lannapsyche tairomyenensis n. sp. (Odontoceridae) are described and illustrated. Polyplectropus hofmaierae n. sp. is distinguished from other species by the shape of the apical end of its inferior appendages and its sharp intermediate appendages. The posterior edges of their inferior appendages run slanting to the ventrodistal point and are densely covered by short and stiff bristles. Eoneureclipsis chinachotiae n. sp. is differentiated by characters of its phallus, as the first two thirds of its length are slender and slightly curved. The distal part has a dorsal hump with a very slender thread on its caudal edge and is slightly bent downward and dilated. Hydropsyche khaonanensis n. sp. can be differentiated from the other species by its phallus, in which the two apicolateral lobes in ventral view have rounded outer edges. Lannapsyche tairomyenensis n. sp. can be separated from the others by characteristics of the dorsal view of segment IX and the harpago of its inferior appendages. Segment IX is triangular with distinctly convex preanal appendages along the posterior edge of this segment, and the harpago and subapical lobes are relatively similar in shape and length.

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

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

Four new species of genus Rhyacophila are described and illustrated from Thailand and Myanmar, Southeast Asia. Rhyacophila longicaudata sp. n. is in the R. nigrocephala Group; the very long basal segment of each inferior appendage distinguishes it from other related species. Rhyacophila aksornkoaei sp. n. and R. limsakuli sp. n. are in the R. anatina Group: they can be differentiated from other species of the group by the brush-like parameres and presence of a ventral process of the aedeagus in R. aksornkoaei sp. n., and by the rectangular apical segment of each inferior appendage and the hooked parameres in R. limsakuli sp. n.. Rhyacophila kengtungensis is in the R. yishepa Group and is characterized by the subtriangular shape of the preanal appendages in dorsal view and by the very large dorsal appendages of the phallic apparatus.

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

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

Two new species of caddisflies, Macrostemum nigralatum n. sp. and Anisocentropus tairomyenensis n. sp., are described and figured from lower-hill evergreen forests in southern Thailand. Wings of M. nigralatum are black, which distinguishes the new species from other related species. Anisocentropus tairomyenensis n. sp. is a member of the subgenus Anisomontropus and is characterized by the obvious basal expansion of the preanal appendages.

RESUMO

Five new species of caddisflies are described from the Upper Tenasserim Range, including Chimarra keawpradubi n. sp., Ecnomus niyomwasi n. sp., Psychomyia pinsuwanae n. sp., Leptocerus suwannarati n. sp., and Setodes lertpongsombatae n. sp., based on distinctive characters of male genitalia. Chimarra keawpradubi n. sp. differs from other Chimarra spp. in ventral aspect of inferior appendages, each of which is rectangular with a bulging process apicoventrally and with an acute apex. The basal part of each inferior appendage is square and the apical part is narrow in E. niyomwasi n. sp., differentiating it from other species in the genus. Psychomyia pinsuwanae n. sp. differs from P. amphiaraos Malicky and Chantaramongkol 1997, a closely similar species, by characters of the inferior appendages; the inner branch of each inferior appendage has a long, straight spine on its inner side. Leptocerus suwannarati n. sp. can be distinguished from other Leptocerus spp. by the processes of segment X, which are long, thin, and symmetrical. Setodes lertpongsombatae differs from other Setodes spp. in characters of segment X, which is deeply divided subapically into two very long saber-like blades in lateral view.

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

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

Three new species belonging to genus Cheumatopsyche Wallengren are described and illustrated. The newly described species are Cheumatopsyche nigrocephala sp. nov. and Ch. similis sp. nov. both from Uttarakhand, and Ch. meghalayaensis sp. nov. from Meghalaya. Cheumatopsyche guadunica Li Dudgeon 1988 is reported for the first time from India. Cheumatopsyche ningmapa Schmid 1975 and Ch. galahittigama Schmid 1958 are also redescribed and reillustrated based on Indian specimens (males only). Due to insufficient description five species described by the Navás are considered to be nomina dubia (Cheumatopsyche chlorogastra (Navás 1932), Ch. indica (Navás 1932), Ch. lebasi (Navás 1932), Ch. stenocyta (Navás 1932), Ch. suffusa (Navás 1932). Previously, this genus was represented by 23 species and, with the addition of 3 new species and one new country record, there are now 27 species known from India.

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 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

Three new species of Ceraclea (Leptoceridae) from Southeast Asia are described and illustrated: Ceraclea (Athripsodina) trisdikooni n. sp. from Myanmar, C. (A.) thongnooi n. sp. from Thailand and Myanmar and C. (A.) thongpongi n. sp. from Laos. Ceraclea trisdikooni n. sp. is distinguished from other species by its inferior appendages recurved ventrad nearly 180° apically. The apex of the basal segment of each inferior appendage is more pointed. In ventral view, each inferior appendage of the new species has an obvious basoventral lobe with numerous long setae. Ceraclea thongnooi n. sp. is distinguished from those by inferior appendages that are each shaped like a seahorse head both in lateral view and ventral view. Ceraclea thongpongi n. sp. is distinguished from other species by the rectangular preanal appendages. In dorsal view, the apical end of segment X is oval and notched apically; in ventral view, the subapicodorsal lobe of each inferior appendage is rounded and straight.
