Morphologically the three species pose difficulties in identification. A comparison of morphological characters of M. indicum, M. australe and M. ustulatum has been made in the paper. The COI sequence data for the species has been generated and made comparison with the existing COI barcode sequences for M. australe and showed clear difference between the species, thereby established the taxonomic validity of the species. Alignment of the present study sequences with reported sequences of M. australe revealed homologous region of 434 bp. Out of 434 nucleotides, the number of conserved and variable nucleotides were 313 and 121, respectively. Based on the P value (0.002) of Mann-Whitney U test, it was observed that the GC content at codon third base position between M. indicum and M. australe is significantly different. Because of the complexity of the species group a type material is highly necessary for confirmation in future studies and since holotype is irrecoverably lost, a neotype has been selected from the present collection and deposited in the CMFRI Museum at Kochi, Kerala with accession number: ED.2.2.1.8.
查看更多>>摘要：Neochauliodes van der Weele is the most species-rich genus of Chauliodinae (Megaloptera: Corydalidae). However, to date there are only five species of Neochauliodes recorded from India. Herein, we report a new species of Neochauliodes, N. flinti sp. nov., from northeastern India. An updated key to the species of Neochauliodes from India and adjacent regions of South Asia is also given.
查看更多>>摘要：A new Malthodes embedded in an amber piece of the Eocene from Kaliningrad region (Russia) is illustrated and described here. Most of the species of this genus, both living and fossil, show short elytra leaving some abdominal segments uncovered, as in the case of Malthodes tognettii sp. nov. The new species is characterized by the absence of the yellow spots on the elytral apex, the last sternite strongly curved and folded backward with weakly forked apex, and by the last tergite elongate, weakly forked apically and slightly bent downwards from half-length. A key of the Malthodes embedded in Baltic amber is also provided.

In addition, morphological photograph of Xizicus (Eoxizicus) divergrntis (Liu & Zhang, 2000) are provided. All the type specimens are deposited in the Museum of Hebei University.
查看更多>>摘要：In this study we examined the original types of 21 of the 56 morphospecies of Xenia currently listed in WoRMS. Unfortunately, our attempts to locate additional type material failed, and we conclude that they have been lost. The type localities of the material examined include the Red Sea, West and Central Indian Ocean, the South Pacific, Indonesia, The Philippines, and the Bismarck Sea, reflecting the extensive biogeographical distribution of this genus throughout the Indo-Pacific Ocean. A neotype was designated from the northern Red Sea for X. umbellata, and sequencing established its position in the phylogenetic tree in relation to other genera of the family Xeniidae. In addition, X. flexibilis n. sp. was described from The Philippines. The findings from the current study led to the synonymizing of X. actuosa with X. sansibariana and of X. plicata with X. blumi. Overall, the study has re-described the types of 17 species considered to be valid based on morphological characters. Validation of the morphological features of original type material along with species-diagnostic genetic characters are required in order to facilitate our ability to correctly employ Latin binomials, both in phylogenetic studies and in any other biological surveys.
查看更多>>摘要：The species of brachypterous Phaneropterinae (Tettigoniidae) inhabiting the 'gum' National Park, Parana, Brazil, were studied. Four species have been recognized, Anisophya melanochloris (Rehn, 1911) and three new species described here: Anisophya una sp. n., as well as Xenicola taroba sp. n. and Xenicola xukrixi sp. n. We present relevant characters used in Orthoptera taxonomy, such as male genitalia, male and female stridulatory files, cerci and subgenital plates for all four species. Calling songs of three species are also described. X xukrixi sp. n. stands out by its high carrier frequency with a peak above 70 kHz.
查看更多>>摘要：We describe a new species, Moridilla jobeli sp. nov., belonging to the marine heterobranch group Aeolidioidea. Up to now, it is only recorded from Bunaken National Park, North Sulawesi, Indonesia. A combination of histological, computer tomographic and scanning electron microscopic methods was applied in order to describe and illustrate the anatomy of Moridilla jobeli sp. nov. in detail. Furthermore, we conducted molecular analyses which include available partial COI and 16S rRNA sequences, as well as the nuclear gene Histone 3 (H3) of Facelinidae and Aeolidiidae. NeighborNet analyses, species delimitation tests and phylogenetic reconstruction methods show the distinctiveness of the new species from the type specics Moridilla brockii Bergh, 1888 and the two recently described species Moridilla fifo Carmona & Wilson, 2018 and Moridilla hermanita Carmona & Wilson, 2018, as well as the monophyly of the genus. A phylogenetic analysis of the Facelinidae and Aeolidiidae does not result in a resolved tree, therefore relationship of former assumed closely related genera, Noumeaella Risbec, 1937 and Palisa Edmunds, 1964, cannot be discussed in detail.
查看更多>>摘要：Maruina is an aquatic genus of Psychodidae with larvae and pupae adapted for life in flowing water. The genus is restricted to the Western Hemisphere, with the majority of species distributed in the Neotropical region. 39 Maruina species are described, with 11 currently known to occur in Brazil, all recorded from the eastern Biomes of Atlantic forest and Caatinga. Here we describe four new Maruina species collected from Brazil: Afaruina (Aculcina) roraimensis sp. nov., Maruina (Maruina) kallyntrona sp. nov. and M. (Al.) mystax sp. nov. constitute the first report of Maruina from Amazonia and M (A.) pi la sp. nov. from the southern portion of the Atlantic forest expands the distribution of the genus to Rio Grande do Sul, the southernmost state of Brazil. Type specimens of some described species were also studied. Redescriptions are completed for M. (M.) garota and M. (M) namorada, and additional characters and figures are presented for Al. (A.) duckhousei, M. (Al.) barrettoi and M. (M.) jezeki. Al. pilosella and M. spinosa are considered nomina dubia. Diagnostic characters for the genus and both subgenera are revised and distribution maps for Maruina species recorded in Brazil are provided.
查看更多>>摘要：The family Euryleptidae, consisting of 19 genera, is as colourful and distinct as the family Pseudocerotidae. Five species of Euryleptidae encountered during surveys in the intertidal rocky shores of Ratnagiri, Maharashtra are presented in the current study. Cycloporus i'ariegatus is new records to India. Cycloporus australis and C. reticulatus are new records to India and reported for the second time after their first formal descriptions in 1982 and 2002 respectively. Eurylepta aurantiaca is a new record to the Indian ocean. The study also describes the new species Stylostomum mixtomaculatum sp. nov. and it is the first report of the genus Stylostomum from the tropical realms. Since Stylostomum and Acerotisa are known to be closely allied genera, efforts have been made to review their species assemblages and throw light on the existing ambiguities within the available information. With this report, the number of euryleptid species from Indian waters increases to eight.
