In Thailand, the genus comprises at least six species, one of which is Anentome wykoffi, a species that may act as an intermediate host of parasitic trematodes. Recent fieldwork has shown that A. wykoffi is far more common and widespread in Thailand than has been assumed, yet the taxonomy remains poorly known. Therefore, this study explores morphological and DNA sequence (COI and 28S rRNA) variation in A. wykoffi to verify and finetune the taxonomic interpretation of this species. To this end, 12 populations of A. wykoffi were sampled in Thailand. This survey allowed us to preliminarily distinguish three putatively cryptic morphotypes. Shell shape measurements and geometric morphometric analyses revealed significant differences between these morphotypes, whereas SEM observations of the shell sculpture and radula confirmed the consistent separation of the three morphotypes. Finally, a combined phylogenetic and species delimitation analysis of COI and 28S rRNA sequence data showed that the three morphotypes represent three well-supported clades, one of which is sister group to A. cambojiensis. As such, the three morphotypes as defined by (1) the presence or absence of a carinated shoulder, (2) the number of spiral lines on the spira and (3) the pattern of the central cusps on the central radular tooth, are interpreted as three different species under the morphological and phylogenetic species concepts but also likely under the biological species concept, viz. A. wykoffi (sensu stricto), A. longispira sp. nov. and A. khelangensis sp. nov. The three cryptic species are (re)described and the implications of separation are briefly discussed.

Several species are threatened with extinction, but there are considerable uncertainties with the present classification. Here, the taxonomy of the species group is revised based on molecular and morphological data. Mitochondrial sequence data were obtained from GenBank for Ogyris Angas, 1847, from cytochrome oxidase I (COI) and cytochrome b (cytb) (total of 1203bp), and a phylogeny of the genus was reconstructed using Maximum Likelihood methods. Based on these molecular data, adult morphology and other evidence, the following eight taxa are recognised in this species group: Ogyris otanes (C. & R. Felder, 1865), Ogyris arcana M.R. Williams & Hay, 2001 stat. rev., Ogyris arcana arcana M.R. Williams & Hay, 2001 comb. nov., Ogyris arcana sublustris M.R.

The female of Ogyris halmaturia halmaturia is described for the first time. Phylogenetic relationships among the six species are as follows: (O. otanes + O. arcana) + (O. halmaturia + (O. idmo + (O. subterrestris + O. petrina))). The life history switch from phytophagy (O. otanes and O. arcana) to entomophagy (suspected myrmecophagy) within this species group has led to diversification of four species, a most unusual evolutionary pattern within the Lycaenidae globally. The taxonomic changes proposed herein affect some of the most threatened Australian butterflies and their conservation status is discussed.

Although the shell morphology, karyotype and molecular phylogeny of the genus have been well studied, the systematic status of several non-monophyletic species remains uncertain. In this study, we have evaluated the taxonomic accounts of the species previously identified as Semisulcospira decipiens, S. habei and relatives. We examined the genetic relationships using genome-wide SNP data and elucidated morphological variation among these using Random Forest classification. Morphological relationships between the name-bearing type of S. decipiens and the newly collected specimens were also evaluated. Morphological characteristics effectively discriminated between the nine genetic clusters, and the correlation among morphology and substrates was elucidated. We revised taxonomic accounts of S. decipiens, S. habei, S. arenicola, S. nakasekoae and S. ourensis and synonymised S. multigranosa, S. habei yamaguchi, S. dilatata under S. decipiens and S. fluvialis under S. nakasekoae. We also described two new species, Semisulcospira elongata sp. nov. and Semisulcospira cryptica sp. nov., and redefined two phylogroups of the lacustrine species as the Semisulcospira niponica-group and the Semisulcospira nakasekoae-group. Traits of the species examined exhibiting intraspecific variation in the different substrates and flow velocity may indicate the morphological and trophic adaptations. The habitat-related variation has certainly caused the taxonomic confusion of the lacustrine species. Lake drainage contributes to increasing the species diversity of the genus, generating ecological isolation between the riverine and lacustrine habitats.","PeriodicalId":54927,"journal":{"name":"Invertebrate Systematics","volume":"36 1","pages":"1139 - 1177"},"PeriodicalIF":2.2,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41635408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We here describe the worker caste of Yavnella, facilitated by maximum-likelihood and Bayesian inference from 473 partitioned ultra-conserved element loci, this dataset including 49 other leptanilline species, both described and undescribed. Yavnella laventa sp. nov. is described from seven worker specimens collected in south-western Iran from the Milieu Souterrain Superficiel, a subterranean microhabitat consisting of air-filled cavities among rock and soil fragments, which is subject to similar environmental conditions as caves. This species has bizarrely elongated appendages, which suggests that it is confined to cavities, in contrast with the soil-dwelling behaviour observed in other leptanilline ants. Based on its gracile phenotype relative to other Leptanillinae, Y. laventa shows remarkable adaptations for subterranean life, making it one of a very few examples of this syndrome among the ants. Moreover, the discovery of the worker caste of Yavnella expands our morphological knowledge of the leptanilline ants. We provide worker- and male-based diagnoses of Yavnella, along with a key to the genera of the Leptanillinae for which workers are known. The worker caste of Yavnella as known from this species is immediately recognisable, but the possibility must be noted that described workers of Leptanilla may in fact belong to Yavnella. Further molecular sampling is required to test this hypothesis.","PeriodicalId":54927,"journal":{"name":"Invertebrate Systematics","volume":"36 1","pages":"1118 - 1138"},"PeriodicalIF":2.2,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41317449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This family probably represents an example of the evolution and persistence of an asexual lineage that differentiated into several taxa without sexual reproduction. Analyses of nuclear and mitochondrial genes (18S, 28S, ITS2 and cox1), and the increase of five taxa to the phylogenetic analyses of Murrayidae led us to infer that Murrayon is polyphyletic, being composed of two ‘species groups’ that also find morphological supports: the ‘dianeae group’ characterised by peculiar egg processes (rod-shaped and covered with a cuticular layer), animals with large, evident epicuticular pillars and small claws; and the ‘pullari group’ characterised by conical egg processes, animals with very small epicuticular pillars, and proportionally larger and longer claws. This latter group is a sister group to Dactylobiotus. Murrayon hastatus is the only species within the genus that has an uncertain position with eggs of the ‘dianeae group’ and animals of the ‘pullari group’. We propose the erection of Paramurrayon gen. nov. (for the ‘dianeae group’ of species), the emendation of Murrayon, and new taxonomic keys for both genera. Possible scenarios of the evolution of taxa within Murrayidae are hypothesised based on synapomorphic characters. Paramurrayon meieri sp. nov. from Norway is described with an integrative approach.

This rarity has consequently constituted the greatest obstacle for understanding the internal relationships due to the low representativeness of species present in any phylogenetic reconstructions.

Our data set includes, for the first-time, information about members of the families Clistoconchidae, Cetoconchidae, Protocuspidariidae, Spheniopsidae and the recently described Bentholyonsiidae. Information on shell morphology, anatomy and behaviour of anomalodesmatans was compiled through a review of the literature (from 1895 to 2022) and a re-analysis of shells and internal anatomy of some freshly collected and archived specimens in museum collections around the world. Our analysis suggests a deep division of the Anomalodesmata into two distinct clades: the first generally composed of shallow water species from 12 families and a second clade of a carnivorous lineage mainly comprising deep water species from 10 families. Consequently, a new topology for Anomalodesmata is suggested bringing new insights into the interfamilial relationships of this sometimes bizarre clade of bivalves.","PeriodicalId":54927,"journal":{"name":"Invertebrate Systematics","volume":"36 1","pages":"1063 - 1098"},"PeriodicalIF":2.2,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59288279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyses of DNA sequence data (COI, 16S rDNA and D2 region of the 28S rDNA) of populations of the apparent morphotype of P. dumerilii obtained from a broader sampling area along European marine waters, including the Azores and Webbnesia islands (Madeira and Canaries), provided compelling evidence for the existence of at least 10 divergent evolutionary lineages. Complementing the genetic data, morphological observations of the better represented lineages revealed two major groups with distinctive paragnath patterns. Two new Platynereis species were erected: P. nunezi sp. nov., widespread in the Azores and Webbnesia islands, and P. jourdei sp. nov., restricted to the western Mediterranean. The new combination P. agilis is also proposed for Nereis agilis, previously unaccepted for one of the lineages present both in the Northeast Atlantic and western Mediterranean. Platynereis dumerilii is redescribed based on topotypic material. However, uncertainty in the identity of P. massiliensis due to the original brief description and the absence of type and topotypic material prevents the unequivocal assignment to the lineage assumed in this and previous studies.

Molecular phylogeny using five genetic markers (three mitochondrial and two nuclear) on 11 of the 12 species known in the family successfully reconstructed a robust phylogenetic tree for the reef lobsters with two well-supported groups. The genus Hoplometopus Holthuis, 1983 is revived but with diagnostic characters revised and H. voigtmanni (Türkay, 1989) should be treated as a synonym of H. holthuisi (Gordon, 1968). Four synapomorphies are identified in Enoplometopidae, including the number of the intermediate and postcervical teeth on the carapace, the shape of abdominal pleura and the spination of the palm of large chelipeds. Fossil calibration and ancestral range reconstruction analyses suggested that reef lobsters had a Tethyan deeper water origin and emerged during the Cretaceous period. Enoplometopus s.s. was relatively primitive, whereas Hoplometopus diverged in the Central Indo-Pacific in the Upper Cretaceous and later crossed the Mediterranean into the Atlantic. Overall the family Enoplometopidae mainly speciated in the Central Indo-Pacific, and actively re-occupied shallow-water habitats and invaded temperate regions.","PeriodicalId":54927,"journal":{"name":"Invertebrate Systematics","volume":"36 1","pages":"973 - 983"},"PeriodicalIF":2.2,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59288243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
