Taxonomy and cladistic analysis of the subgenus Xenomorellia Malloch (Diptera: Muscidae: Morellia Robineau-Desvoidy) with description of two new species

Xenomorellia Malloch, a subgenus of Morellia Robineau-Desvoidy, is revised to include two new species, Morellia (Xenomorellia) inca Nihei and Carvalho sp. nov. from South America, and M. (X.) maia Carvalho and Nihei sp. nov. from Costa Rica and Mexico. Diagnoses for M. (X.) holti (Malloch) and M. (X.) montanhesa (Albuquerque) are provided, as well as an identification key to the four species of the subgenus. A cladistic analysis was performed to test the monophyly of Xenomorellia and to recover the phylogenetic relationships among its species. Tree searches resulted in one single most-parsimonious cladogram, wherein the monophyly of Xenomorellia is supported, as well as a sister-group relationship with the Neotropical subgenus Trichomorellia Stein. Xenomorellia was divided into two clades: one with Caribbean–Andean species (maia?+?inca), and another with species from southeastern South America (holti?+?montanhesa).     

Cylindropygus ferox gen. n., sp. n.: A new member of the Cryptopygus complex (Collembola,Isotomidae) from central France

Cylindropygus, a new genus of isotomid Collembola, is described. It differs from all other genera of Isotomidae by a unique combination of characters (abdominal segments V and VI fused, eyes absent, postantennal organ present and elongate, S‐chaetotaxy, and absence of foil chaetae) and two remarkable features: a modified labium, with papillae A, B, D bearing strong spines; and a swollen, globular accp3 chaeta on Abd.V. Cylindropygus ferox sp. n. is common in forest soils of central France.     

Phylogenetic relationships of millipedes in the subclass Penicillata (Diplopoda) with a key to the genera

Bristly millipedes (subclass Penicillata, order Polyxenida) are minute diplopods characterised by uncalcified cuticle and a body covered with unique tufts of bristles. The order is found worldwide and comprises less than 200 described species divided into three families, with many of the species and genera being poorly known. The first evolutionary analysis of the order presented here utilises both molecular (COI, 18S rRNA and 16S rRNA) and morphological data to examine monophyly of the families and subfamilies and the evolutionary relationships between them. Maximum likelihood analysis was based on molecular data only, whereas parsimony analyses were based on molecular data as well as combined morphological and molecular data. The results of these analyses with two different optimality criteria were incongruent in many aspects. Unlike parsimony, the likelihood result found strong support for a basal position of the family Synxenidae and separation of the order into two monophyletic clades corresponding to the two superfamilies Synxenoidea, containing the family Synxenidae, and Polyxenoidea, containing the families Polyxenidae and Lophoproctidae. Parsimony results did not support the existence of the two superfamilies. Both analyses resolved the family Synxenidae as monophyletic and Polyxenidae as polyphyletic, whereas the family Lophoproctidae was shown to be paraphyletic in likelihood and monophyletic in parsimony analysis. The subfamilies Monographinae and Polyxeninae were found to be monophyletic in the likelihood tree but parsimony suggested paraphyly of both. The results suggest that further revision of the systematics of the Polyxenida may be necessary. However, a much larger molecular data set will be necessary to clarify and provide stronger nodal support for phylogenetic trees and to confirm the relationships, particularly of the families Polyxenidae and Lophoproctidae. Molecular identification is likely to be an important tool for this taxonomically challenging order in future. A simplified key to the genera is provided.     

Australian species of Sinella (Coecobrya) Yosii, 1956 (Collembola: Entomobryidae)

The Australian members of the subgenus, Sinella (Coecobrya) Yosii, are revised. A new species from Western Australia, Queensland, and the Northern Territory, Sinella (Coecobrya) tropicalis sp. nov., is described, Sinella (Coecobrya) tenebricosa Folsom, 1902 is recorded from Australia for the first time, and new records of Sinella (Coecobrya) communis Chen and Christiansen, 1997 Chen, J‐X. and Christiansen, K. A. 1997. Subgenus Coecobrya of the genus Sinella (Collembola: Entomobryidae) with special reference to the species of China.. Annals of the American Society of Entomology, 90: 1–19.  [Google Scholar] are documented. Sinella (Coecobrya) caeca Schött, 1896 is considered a dubious record from Australia. A key is provided to the three known Australian species and a summary given of all dorsal and lateral chaetal patterns found on the fourth abdominal segment of subgenera Sinella Brook, 1882 Brook, G. 1882. On a new genus of Collembola (Sinella) allied to Degeeria Nicolet.. Journal of the Linnean Society of London (Zoology), 16: 541–545.  [Google Scholar] and Coecobrya Yosii, 1956 Yosii, R. 1956. Hohlencollembolen Japans II.. Japanese Journal of Zoology, 11(5): 609–627.  [Google Scholar]. The biogeography of the subgenus is described.     

Review and reclassification of Cataglyphis (Hymenoptera,Formicidae)

Exactly 100 years ago Forel made a misidentification of Cataglyphis viaticus as C. megalocolus, one of the most characteristic insects of North Africa. This farreaching error has influenced the systematics of the genus ever since. What really are the species of Cataglyphis? Cataglyphis is unique among formicine ants in that the morphology of the male genitalia is highly diverse: their characteristics are used for the differentiation of species groups and as a basis for postulated phylogenetic relationships within the genus. A synopsis, a key to the species-groups, and a full catalogue of all the available names are given. Of the 104 taxa currently recognized as valid, Cataglyphis albicans var. mixtus is a new combination, Cataglyphis cursor ssp. flavicornis is transferred to Alloformica, and Cataglyphis mauritanicus and Cataglyphis nigripes are given a new status. Camponotus phaenogaster is a new synonym, and Cataglyphis hispidus is a nomen nudum. A lectotype has been fixed for Cataglyphis savignyi.     

Two new Sarsiellinae (Ostracoda: Myodocopa) from Ningaloo Reef (Western Australia), with a cladistic analysis of the subfamily and keys to genera

Two new Sarsiellinae from Ningaloo Reef, Spinacopia ningalooi sp. nov., and Metasarsiella caleyi sp. nov. are described. Spinacopia ningalooi is the first representative of the genus collected from a coral reef. It differs from the other species by its odd looking posterior infold. Metasarsiella caleyi sp. nov. is the first species of the genus reported from Australia. Keys to species of Spinacopia Kornicker, 1969 Kornicker, LS. 1969. Morphology, Ontogeny, and Intraspecific Variation of Spinacopia, a new genus of myodocopid ostracod (Sarsiellidae). Smith Contr Zool., 8: 50 [Google Scholar] and Metasarsiella Kornicker, 1991 Kornicker, LS. 1991. Myodocopid Ostracoda from Enewetak and Bikini Atolls. Smith Contr Zool., 505: 140 [Google Scholar], and to all the genera of Sarsiellinae are given here, together with an inventory of all the species and information on their distributions and biology. The results of two cladistic analyses (with unweighted and with weighted characters) of the subfamily based on 138 species and 34 morphological characters are presented. The first analysis resulted in seven equally parsimonious trees and the second in just one. The majority rule of the first group of trees and the tree from the second analysis are presented here.     

A phylogenetic review of the genus Atopobathynella Schminke, 1973 (Crustacea,Malacostraca, Bathynellacea) with three new species from southeastern India

To date, the genus Atopobathynella Schminke, 1973, contains 12 Gondwanan species, including two species from India. Three new species of this genus, viz. A. indica sp. nov., A. nelloreensis sp. nov., and A. inopinata sp. nov., from southeastern India are described herein. The various characters and their states in Atopobathynella, in relation to other parabathynellid species known so far, are discussed; especially its closeness with the genus Kimberleybathynella is highlighted. A morphological phylogenetic analysis of the genus Atopobathynella,along with its closely related genus Kimberleybathynella is also done, and the inter-relationships among the 15 species of Atopobathynella and six species of Kimberleybathynella are deduced, using the software PAUP 4.0b10. This analysis, based on 39 unordered characters, has yielded 23 most parsimonious trees, with a length of 138 steps, a consistency index (CI) of 0.3768, a homoplasy index (HI) of 0.6232, a retention index (RI) of 0.6211, and a rescaled consistency index (RC) of 0.2341. The cladogram thus obtained suggests the grouping of ((A.wattsi, A. glenayleensis), (A. readi, ((((A. gascoyneensis, A. hospitalis), A. hinzeae), (((A. compagana, A. chelifera), A. valdiviana), (((A. operculata, A. paraoperculata), A. nelloreensis), (A. indica, A. inopinata)))), (A. schminkei, (((((K. gigantea, K. kimberleyensis), K. argylensis), K. pleochaeta), K. mandorana), K. hexapoda)))), outgroup). It also shows that the five Indian species are nestled between the Australian Atopobathynella and Kimberleybathynella species. The Indian species appear to be much derived as compared to their Australian counterparts. A brief note on the origin of Bathynellacea is also added at the end.

Diplecogaster tonstricula,a new species of cleaning clingfish (Teleostei: Gobiesocidae) from the Canary Islands and Senegal,eastern Atlantic Ocean,with a review of the Diplecogaster-ctenocrypta species-group

The Diplecogaster-ctenocrypta species-group is reviewed; it comprises two species. The clingfish Diplecogaster ctenocrypta from the Canary Islands is redescribed. The new species Diplecogaster tonstricula, a facultative cleaner of other teleosts, is described on the basis of eight specimens and colour photos from Senegal and the Canary Islands, eastern Atlantic Ocean. The species is small, apparently not exceeding 23 mm total length; it is characterised by having nine dorsal-fin rays, eight anal-fin rays, 24–25 pectoral-fin rays, 14–15 principal caudal-fin rays, 13–16 rakers on third gill arch, pelvic disc without lateral papillae in region A, disc region B with two rows of weak papillae, interorbital distance 4.1–4.6 in head length, distance between disc and anus 14–17% of SL, head and body with 10–13 narrow vertical brownish bars, cheek with a white ocellus surrounded by black, and with a small black spot in the middle. The new species is compared with other species of the genus; a key to the six known species of the eastern Atlantic, Mediterranean and Black Sea and South African genus Diplecogaster is presented. A checklist is provided for the species of Diplecogaster and their synonyms.     

A new genus and subfamily of Typhloplanidae (Platyhelminthes,Rhabdocoela) from Australia with a cladistic analysis of subfamily relationships

During a survey of marine interstitial Platyhelminthes of North Stradbroke Island, Queensland, Australia, a new taxon of Typhloplanidae (Rhabdocoela) was found, namely Cephalopharynx cannoni gen. nov. sp. nov. This new monotypic genus combines a suite of characters that set it apart from the remaining 63 genera present in the known eight subfamilies. It is unique in the lack of adenal and dermal rhabdites, the anterior position of the pharynx rosulatus, presence of a single anterior testis, and novel stylet structure. These character states substantiate the erection of a new subfamily, Cephalopharynginae, based on cladistic criteria. A key to the subfamilies of Typhloplanidae is provided.     

Generic classification of the family Pipunculidae (Diptera): a cladistic analysis

Classification of the higher taxa of the Pipunculidae is analysed by cladistic techniques. Twenty-five taxa are studied, and 117 character states are examined for these taxa. Based on the cladistic analysis a classification is proposed, recognizing three subfamilies: Chalarinae, Nephrocerinae, and Pipunculinae. The subfamily Pipunculinae is separated into five tribes: Pipunculini, Cephalopsini trib. nov; Microcephalopsini trib. nov., Eudorylini trib. nov., and Tomosvaryellini. Monophyletic genus groups within these tribes are recognized. The position of Claraeosphaera is unclear. Twenty-three taxa of generic status are recognized, and Wittella is considered synonymous with Cephalops. The genus Collinias is revalidated. Claraeomorpha is retained as a subgenus of Dorylomorpha. A presumed phylogenetic history of the taxa and evolutionary transformation series for certain characters are extrapolated from the analysis.     

The female genitalia of Gonioctena,subgenus Spartoxena (Coleoptera: Chrysomelidae)

The taxonomy of the eight species of Gonioctena Chevrolat belonging to the subgenus Spartoxena Motschulsky is mostly based on male genitalia due to the unsuitability of external characters (i.e. coloration patterns) for identification. In order to provide similar diagnostic characters for both genders, the female genitalia of the eight species are described and illustrated. Considering the lack of spermathecae within the genus, the shapes of tergite 8, and sternites 8 and 9 have been explored as possible diagnostic characters. These structures present marked differences between taxa and simultaneously stability among individuals of each species, and thus they are very useful for taxonomic purposes. A key to the females of the subgenus Spartoxena is provided, and figures of tergite 9, and sternites 8 and 9 of each species are included.     

A taxonomic review of the Rhinotermitidae (Isoptera) of Thailand

Ninety series of rhinotermitid termites were collected from 19 localities distributed across much of Thailand, and compared with specimens deposited in the NHML. Eleven species belonging to five genera of Rhinotermitidae are recorded from Thailand. Three species of two genera, Reticulitermes (Reticulitermes assamensis) and Parrhinotermes (Parrhinotermes microdentiformisoides and Parrhinotermes buttelreepeni), are new records from Thailand. Keys to the genera and species based on the soldier caste are given. Soldiers of all species are illustrated and morphological measurements are given.

Karkata,a new genus of gecarcinucid freshwater crab with two new species,and four new species of Pilarta Bahir and Yeo, 2007 and Cylindrotelphusa Alcock, 1909 (Decapoda: Brachyura) from Kerala,India

A new genus of freshwater crab, Karkata gen. nov., with two species, K. ghanarakta sp. nov. (type species) and K. kusumbha sp. nov., and two new species each of Pilarta Bahir and Yeo, 2007 (P. aroma sp. nov. and P. punctatissima sp. nov.) and Cylindrotelphusa Alcock, 1909 (C. breviphallus sp. nov. and C. longiphallus sp. nov.), are described from Kerala, India. Additionally, C. granulata (Pillai, 1951) comb. et stat. nov. is recognised as a distinct species. Karkata gen. nov. is distinguished from other Indian gecarcinucid genera by a suite of carapace and gonopod characters, including a moderately arched, smooth carapace, the presence of a prominent suture between male thoracic sternites 2, 3 and 3, 4, the absence of a flagellum on the third maxilliped exopod, a very short terminal segment of the male first gonopod (G1), and a short distal segment of the male second gonopod (G2). Karkata ghanarakta sp. nov. is differentiated from K. kusumbha sp. nov. by the shape of the G1 subterminal segment and its live colouration. Pilarta punctatissima sp. nov. is distinct among the congeners mainly by its densely punctate carapace, densely setose anterolateral and posterolateral margins of the carapace, stouter G1 terminal segment, and relatively long G2 distal segment whereas P. aroma sp. nov. can be separated from P. anuka Bahir and Yeo, 2007 by its relatively smooth carapace, deep H-shaped groove, relatively long G1 terminal segment, and almost straight outer margins of the G1 terminal and subterminal segments. Cylindrotelphusa breviphallus sp. nov. is differentiated from C. longiphallus sp. nov. and C. steniops (Alcock, 1909) by its stout G1, with a stout, short terminal segment. Cylindrotelphusa longiphallus sp. nov. is distinguished from the congeners by its shallow, narrow cervical grooves and relatively slender ambulatory legs. An identification key to the species of Karkata, Pilarta and Cylindrotelphusa is provided.

A revision and phylogenetic re-evaluation of the family Schizopodidae (Coleoptera,Buprestoidea)

The Schizopodidae (formerly subfamily Schizopodinae, family Buprestidae) is elevated to family status, based on a review of its morphology including wing venation, male and female genitalia, larvae, and also a cladistic analysis of in-group and out-group comparisions. Two tribes are recognized: Schizopodini LeConte with one genus, Schizopus LeConte and Dystaxiini Théry with two genera: Dystaxia LeConte and Glyptoscelimorpha Horn. The genus Schizopus contains two species: S. laetus LeConte and S. sallei Horn with one new subspecies, S. sallei nigricans Nelson. The genus Dystaxia includes two species: D. murrayi LeConte, and D. elegans Fall. The genus Glyptoscelimorpha is separated into two subgenera: G. (s. str.) with two species, G. marmorata Horn, and G. viridis Chamberlin; and G. (Dystaxiella) Knull, new status, with one species, G. (D.) juniperae (Knull), new combination, with a new subspecies, G. (D.) juniperae viridiceps Nelson. All taxa are described and information on variation, type localities, distribution, biology, and comparisons are given for each species. Keys to taxa for tribes to subspecies are provided. Illustrations for all species, including habitus, male and female genitalia and other parts, as well as cladograms of relationships are presented. Lectotypes are designated for the following: Yermoella helferi Obenberger, Dystaxia elegans Fall and Glyptoscelimorpha marmorata Horn. Tables of taxa, characters and character states used in the cladistic analysis are included.
