RESUMO

Last year I reported the rediscovery in Cambodia of Lestes nigriceps Fraser, 1924, described from Pusa, India (Fraser 1924a) but never reported since that time from India (Kosterin 2018). In my paper I presumed non-conspecificity of the male and females of the type series and made critical comments on Fraser's appendage drawing (Fraser 1924a: plate IX: 6) and verbal descriptions (Fraser 1924a; 1933) of this species but did not consider his key for Lestes Leach, 1815 in the 1st volume of "Fauna of British India including Ceylon and Burma. Odonata" (Fraser 1933). Later I found a considerable corruption in this key, which could lead to misidentifications. (It is noteworthy to stress that Fraser explicitly provided keys for males only).

RESUMO

The taxa of the genus Macrogomphus Selys, 1858 occurring in continental south-east Asia are reconsidered. Macrogomphus rivularis Förster, 1914 (described from Vietnam), M. borikhanensis Fraser, 1933 (described from Laos), and M. guilinensis Chao, 1983 (described from China), are synonymised with M. albardae Selys, 1878. The relationship and conspecificity of the latter with M. parallelogramma Burmeister, 1839 are doubtful, perhaps they are bona species. Males of M. albardae (and seemingly of parallelogramma as well) are approximately trimorphic for the pale pattern of the abdominal S3-S6, being of either a 'dashed morph' (with small isolated anteriolateral spots and conspicuous middorsal streaks), or a 'ringed morph (with broad anterior rings and less conspicuous middorsal streaks), or an 'intermediate morph'. Validity of the species M. matsukii Asahina, 1986 is doubted; its holotype could be an aberrant male of M. albardae. The main diagnostic character of M. albardae, M. phalantus Lieftinck, 1935 and probably M. parallelogramma, is clarified to be the structure of the cercus inner branch. M. phalantus jayavarman subsp. nov. is described from temporarily inundated forest at the northern bank of the great Lake Tonlé Sap of Cambodia (Siem Reap Province, 1.5 km SSW of Kampong Pluk village, 13.1956° N, 103.9725° E, 3 m a.s.l.), which is ca 1,300 km north and overseas from the presumed range of M. phalantus phalantus.

RESUMO

Euphaea cyanopogon sp. nov. is described and illustrated from specimens of both sexes collected in the Kampongsaom Peninsula in southern Cambodia and the adjacent Phú Quoc Island in Vietnam, both in the Cardamom ecoregion; the holotype ♂ (at RMNH, Leiden) is from Kbal Chhay Waterfall, Cambodia. The male is characterized by having rather narrow wings without areas of strong pigmentation and a face marked with bright blue. The differences and affinities of the new species with E. pahyapi Hämäläinen, 1985 and some of its other congeners are discussed.

RESUMO

Amphicnemis valentini sp. nov. is described from the Ream Peninsula of Cambodia (holotype: Cambodia, Preah Sihanouk Province, Ream Peninsula, 10.52258 N 103.69556 E, RMNH) and Phú Quoc Island, Kien Giang Province of Vietnam, both in the Cardamom ecoregion. It is similar to A. gracilis Krüger, 1898, which occurs in Peninsular Malaysia and Sumatra, but differs from it by a long process on the male prothorax.

RESUMO

Organellar genomes may shed light on complicated patterns of plant evolution at inter- and intraspecies level. Primary structure of plastid genomes sequenced in this study and taken from public databases was characterised and compared in 22 diverse, mostly wild representatives of the genus Pisum (peas). Phylogenetic trees reconstructed via Bayesian approach on the basis of entire plastid genomes resembled those reconstructed on the basis of a nuclear gene His5 coding for a minor histone H1 subtype. They reveal Pisum fulvum as an early divergence of the genus but do not support other taxonomical subdivisions. The positions of three accessions, classified as P. sativum subsp. elatius (the wild subspecies of the common pea), appeared quite unexpected. On the entire plastid genome tree, two accessions, from the Black Sea area of Turkey and Georgia, clustered with representatives of another species, P. fulvum, while the other, from Greece, was the first divergence of the P. sativum branch. We suppose these unusual plastid genomes to be ancient lineages ascending to a 'missing link' between P. fulvum and P. sativum, represented by accession Pe 013 from Turkey. Accessions with common pea appearance but deeply diverged plastids could occur through occasional crossing of diverged pea lines in the past and biparental plastid inheritance, both events being possible in peas.

RESUMO

The spelling of the specific name of an Anormogomphus species in its original description by Bartenev (1913) was variable, kiritshenkoi (5 times) vs kiritschenkoi (1 time). Bartenev himself did not mention this species in his further publications. Later authors proceeded to use different spelling versions of this name, including those not in the original paper. According to the International Code of Zoological Nomenclature (ICZN), the valid spelling should be chosen by the First Reviser. Acting as such, we choose as valid the name spelling Anormogomphus kiritshenkoi Bartenev, 1913, since it predominates in the original description, appears in the species subtitle, and is a proper transliteration from Cyrillic to Latin. It also corresponds to the spelling of his name used by A.N. Kiritshenko himself. Information of the type locality of the species is provided.

RESUMO

Lestes nigriceps Fraser, 1924 was described from a male (later the lectotype) and two non-conspecific females collected in 1922 at Pusa, Bihar State, India, and has never been reported since. In June 2018 a population of L. nigriceps was unexpectedly found in eastern Cambodia, Mondulkiri Province. The Cambodian males, their variation and, for the first time, the true female of L. nigriceps is described.

RESUMO

Coeliccia rolandorum sp. nov. is described from the eastern Cambodia (holotype: Cambodia, Mondulkiri Province, Buu Sraa Waterfall environs, 12°34' N 107°24' E, ~780 m a.s.l., 16 June 2014, RMNH) and southern and central Vietnam. It is related to C. kazukoae, which is known from the Cardamom and Sankamphaeng Mts., and replaces it in eastern Indochina. New distributional data on C. kazukoae are presented and its characters are discussed with respect to their change with age.

RESUMO

Taeniopteryx araneoides Klápalek, 1902, a stonefly species with brachypterous males, known historically from the Danube, Elbe, and Dniester rivers, but considered to be extinct at least in Europe for more than a century. This species has also been doubtfully reported from Krasnoyarsk, Central Siberia. However, we report this species to be still thriving in the Irtysh River at the cities of Omsk (West Siberia, Russia) and Pavlodar (North Kazakhstan). The occurrence of this species reported least fifty years ago from the Yenisey River at Krasnoyarsk, Russia is considered possible. Unlike the widespread Palaearctic T. nebulosa (Linnaeus, 1758) that occurs in a broad range of stream types, T. araneoides is a potomon species, apparently confined to large rivers. In this habitat, it appears vulnerable to anthropogenic impacts and may be unable to compete with T. nebulosa. The construction of dams and reservoirs has apparently extirpated T. araneoides from most of its former geographical range.

RESUMO

Wolbachia are common endosymbiotic bacteria of Arthropoda and Nematoda that are ordinarily transmitted vertically in host lineages through the egg cytoplasm. Despite the great interest in the Wolbachia symbiont, many issues of its biology remain unclear, including its evolutionary history, routes of transfer among species, and the molecular mechanisms underlying the symbiont's effect on its host. In this report, we present data relating to Wolbachia infection in 120 species of 13 Lepidoptera families, mostly butterflies, from West Siberian localities based on Multilocus sequence typing (MLST) and the wsp locus and perform a comprehensive survey of the distribution of Wolbachia and its genetic diversity in Lepidoptera worldwide. We observed a high infection incidence in the studied region; this finding is probably also true for other temperate latitude regions because many studied species have broad Palearctic and even Holarctic distribution. Although 40 new MLST alleles and 31 new STs were described, there was no noticeable difference in the MLST allele content in butterflies and probably also in moths worldwide. A genetic analysis of Wolbachia strains revealed the MLST allele core in lepidopteran hosts worldwide, viz. the ST-41 allele content. The key finding of our study was the detection of rampant recombination among MLST haplotypes. High rates of homologous recombination between Wolbachia strains indicate a substantial contribution of genetic exchanges to the generation of new STs. This finding should be considered when discussing issues related to the reconstruction of Wolbachia evolution, divergence time, and the routes of Wolbachia transmission across arthropod hosts.

RESUMO

In the current sense, Merogomphus Martin, 1904, is an artificial genus. It includes two unrelated groups of species: those with lyrate cerci with or without an outer spine and those with simple cerci, plus two species with large and broad epiproct branches placed in Merogomphus obviously in error. At the same time a number of species similar and obviously related to the former group were described from China in the genus Anisogomphus Selys, 1857. To resolve this taxonomic tangle, the genus Merogomphus is restricted to include only species with lyrate cerci: M pavici (Martin, 1904) (the type species), M. longistigmus (Fraser, 1922), M. vandykei (Needham, 1930), M. femoralis (Laidlaw, 1931), M. vespertinus (Chao, 1999) and M. torpens (Needham, 1930). A new genus Euthygomphus (type species: Platygomphus martini Fraser, 1922) is erected to contain species with simple cerci and moderately divergent epiproct branches, formerly attributed to either Merogomphus or Anisogomphus: Euthygomphus parvus (Krüger, 1899) comb. nov., E. martini (Fraser, 1922) comb. nov., E. koxingai Chao, 1954 comb. nov., E. chaoi Liu 1991 comb. nov., E. jinggangshanus Liu, 1991 comb. nov., E. yunnanensis Zhou et Wu, 1992 comb. nov. Euthygomphus schorri  Kosterin, 2016, sp. nov. is described (type locality: Cambodia, Mondulkiri Province, 3.5-3.8 km ESE of Sen Monorom, holotype in RMNH), A new synonymy Merogomphus chaoi Yang & Davies, 1993 = Anisogomphus pinratani Hämäläinen, 1991, and a new combination Anisogomphus tamdaoensis (Karube, 2001) comb. nov. are proposed [corrected]. The published records of 'Merogomphus parvus' from Laos, Thailand, Vietnam, Cambodia and Vietnam are reidentified as E. yunnanensis, and new records and illustrations of this species from Cambodia are provided.

RESUMO

Microgomphus alani sp. nov. is described from two males from the coastal southwestern foothills of the Cardamom Mts. in southwestern Cambodia (type locality: Cambodia, Koh Kong Province, 17 km ENE of Koh Kong, 'Macromia Rivulet', 11°40'17'' N, 103°07'28'' E, 296 m a.s.l., 3 vi 2014, RMNH). The species is characterised by its small size (hindwing 21-23 mm), cerci with outer angulations, truncated apices and crescent-shaped inner arms sprouting from their middle and not reaching their apices, synthorax with two parallel black lateral stripes and dorsal and collar yellow stripes fused in 7-like manner. Probably females of the same species were earlier reported from Phrae Province in northern Thailand.

RESUMO

Prodasineura hoffmanni sp. nov. is described from Annamense Mountains in eastern Cambodia (holotype: Cambodia, Mondulkiri Province, 4.2 km SE of Dak Dam village, 12°23'10-18'' N 107°19'22-30'' E, 877-878 m asl, 14. VI. 2014, RMNH). The species has a blue pattern, and the male is characterised by medium-broad blue stripes on synthorax and blue colour at the end of the abdomen confined to a tiny spot on S9, dorsum of S10 and cerci. A female of P. doisuthepensis Hoess, 2007 is described. Based on original descriptions, the following synonymy is proposed: Prodasineura fujianensis Xu, 2006 = Prodasineura huai Zhou et Zhou, 2007, syn. n.

RESUMO

In southern West Siberia, as many as four Leptidea Billberg, 1820 species are present sympatrically: Leptideaamurensis (Ménétriés, 1859), Leptideamorsei (Ménétriés, 1859), Leptideasinapis (Linnaeus, 1758) and Leptideajuvernica Williams, 1946. The two latter were recently recognised as nearly sibling species on morphological and molecular characters. Specimens intermediate as to their subtle diagnostic characters occurring in West Siberia and elsewhere were interpreted as resulted from limited introgression. This supposition was tested via populational morphological and molecular analysis of spring brood specimens of all the four species taken from a limited (4.5 × 0.2 km) area in the suburbs of Novosibirsk. The samples were analysed with respect to the genitalic morphology, external characters, three nuclear (CAD, H1 gene and ITS2) and one mitochondrial (COI) molecular markers, infection of the intracellular maternally inherited bacterial symbiont Wolbachia Hertig, 1836 and its wsp gene coding for a hypervariable surface protein. Interspecific variation of the nuclear CAD and ITS2 sequences and the mitochondrial COI gene in Leptideasinapis and Leptideajuvernica turned out concordant. The absence of molecular evidence of introgression suggests genetic integrity of these two species and allows their reliable identification by molecular characters. The genitalic (lengths of the saccus and valva) and external characters (wing pattern) of males overlap in Leptideasinapis and Leptideajuvernica, as identified by molecular markers and thus are not so helpful in actual species identification. Only the ductus bursae length showed no overlap and can be used for identification of females. The histone H1 gene appeared five times less variable over the four studied species than COI, and found to be identical in species Leptideasinapis and Leptideajuvernica. Wolbachia infection was found in all studied species. We identified three wsp variants of Wolbachia: 1) wsp-10 allele in Leptideaamurensis, Leptideasinapis, Leptideajuvernica; 2) a very similar wsp-687 allele in Leptideasinapis; and 3) wsp-688, highly divergent to the previous ones, in Leptideamorsei.
