This study reports data on the prevalence, morphology, and morphometry of the nematodeCheilospirura hamulosaon the basis of light and stereoscopic microscopy and also camera lucida. Specimens were recovered after necropsies of 100 partridges (Alectoris chukar) from Taleqan County in Alborz Province, Iran. The prevalence ofC. hamulosain partridges was of 30% with a mean intensity of 3.9 and range of infection of 1–12. The mean length and width of females were17.5±2.14and0.39±0.04 mm, while those of males were12.2±0.67and0.3±0.06 mm, respectively. The characteristic digitiform tail was observed in females, and the unequal spicules, caudal alae, and ten pairs of caudal papillae were seen in males. The taxonomic characteristic longitudinal cordons and muscular and glandular oesophagus were observed in both sexes. Ratio between cordons and body length in males and females was 1 : 1.33 and 1 : 1.68, respectively. Ratio between long and short spicules in males was 1 : 2.3. The average size of embryonated eggs was51.25×29.5 μm. In the present study,C. hamulosa(Nematoda: Acuarioidea) is recorded for the first time from partridges in Iran. Therefore, the morphological characters described in this study will be useful in the future diagnostic and taxonomic studies of Acuarioidea family.

Within the scorpion genus Vaejovis C.L. Koch, the “mexicanus” group is composed of species distributed in the mountains of México. This group presents taxonomic problems, because its characterization and the species included in the group have varied through the years. In the present work, we redefine this group based on several morphological characters, and we differentiate it from the other two species groups within the genus: “vorhiesi” and “nit dulus+nigrescens”. Additionally, five new species are described: Vaejovis ceboruco sp. nov., Vaejovis nanchititla sp. nov., Vaejovis santibagnezi sp. nov., Vaejovis talpa sp. nov. and Vaejovis tapalpa sp. nov; the males of three species are described for the first time (V. dugesi, V. nigrofemoratus and V. tesselatus); and the updated diagnosis for all species is included. Keys for the identification of males and females of the 30 species included in this group are given. Lastly, notes on the natural history and distribution of some species are provided, with maps of known distribution for all the species.

Details of egg, larval, and pupal morphology are described and illustrated for Calycopis bellera (Hewitson) and C. janeirica (Felder), with a special emphasis on larval chaetotaxy. Wild-caught Calycopis females laid eggs on dead leaves in the laboratory, and the caterpillars successfully completed development on an artificial agar diet to which no leaves were added. Males and females of the sexually dimorphic C. bellera had been previously placed in different genera or different species groups. Calycopis janeirica had been chronically misidentified (and misspelled C. jeneirica). Males and females of this species appear to be correctly associated for the first time. Whereas C. bellera has five larval instars—as reported previously for C. caulonia—C. janeirica has four. Morphological characters of the immatures of C. bellera and C. janeirica are summarized in a table and compared with those of other reared Calycopis species.

Bethylinae are a morphologically well-defined subfamily of Bethylidae, with remarkable characters, such as strongly convex clypeal carina and bifid and angled tarsal claws. However, there is no consensus about the phylogenetic relationships among the genera within the family, regarding mainly Eupsenella and Lytopsenella. To resolve this problem, a phylogeny of the Bethylinae is inferred based on parsimony analyses separately of 43 and 44 morphological characters for males and females, respectively. We performed combined analyses of both sexes with 49 morphological characters, including genitalia. We present a phylogenetic analysis, including a total 118 species of Bethylinae. Male and female characters were included in these analyses. We discuss wing morphology and deformability of forewings for the first time. In summary, the basal polytomy was solved for the first time. Seven of the eight genera were recovered as monophyletic groups. The unique exception is Goniozus, which was retrieved as paraphyletic in all topologies.

Hypocerides Schmitz comprises seven species of considerable morphological similarity according to authors that described or reviewed material from the genus. This lack of variation is problematic for its taxonomy as little is known about which structures could be evidence for species recognition or even about which sex is the most informative to its species-level taxonomy. In this study, I examined males and females of the genus from the Neotropical, Nearctic, and Palearctic Regions in search of informative morphological characters for the genus taxonomy. The examination included types of five of the seven known species and new material from the Neotropical Region and Madagascar. I present a detailed description of the genus, illustrate some of its structures for the first time, and compare the morphology of the specimens examined. Few morphological differences were found but none was considered sufficient to infer species limits. This morphological uniformity among species from different biogeographic regions can be seen as evidence that they could all be one species with an almost worldwide distribution. The low morphological variation among Hypocerides species and their apparent wide distributions remain interesting biological questions.

We describe Simulium guaporense Py-Daniel adults and redescribe some morphological characters of its larvae and pupae based on specimens collected near the type locality in Rondônia State, Brazil. We report this species for the first time in Mato Grosso State. This species was placed originally in the S. siolii species group of the subgenus Psaroniocompsa; however, the thoracic pattern of the adults of S. guaporense is similar to that of species in the S. auristriatum species group. The immature stages were found on deciduous leaves and trailing vegetation in sandy-bottomed streams. Females were collected biting humans.

The paederine genus Paederus s.l. (Coleoptera : Staphylinidae) is a hyperdiverse group of some 500 species worldwide. Although the subtribe Paederina, in which the genus resides, is monophyletic the status of numerous genera and subgenera is questionable and the current classification is likely to be flawed. As part of detailed studies on the paederine fauna of China, we undertook a preliminary morphologically-based phylogenetic analysis to determine the relationships of Paederus (Gnathopaederus) and related subgenera, as a basis for a revision of the subgenus, and as an attempt to provide a better framework for future taxonomic studies on the group as a whole. The analysis was based on 66 adult morphological characters for 30 ingroup taxa, including all six species of P. (Gnathopaederus). The results show that P. (Gnathopaederus) and P. (Paederus), and the genera Megalopaederus, Pachypaederus and Paederidus are monophyletic, and that P. (Eopaederus) and P. (Harpopaederus) are paraphylyetic. However, our analysis did not offer a robust solution to relationships among other clades within Paederus s.l. although it seems clear that Paederus s.l. is not monophyletic with respect to the above genera. The monophyly of P. (Gnathopaederus) is supported by the mandibular basal medial tooth having two cuspids separated dorsoventrally. Based largely on this character state, the definition of the subgenus is refined; six species are recognized, including two new species described from China as follows: P. (G.) daozhenensis, sp. nov. from Guizhou, and P. (G.) jilongensis, sp. nov. from Xizang; three species, P. bursavacua Willers, P. yunnanensis Willers and P. solodovnikovi Willers, are newly assigned to the subgenus according to a revised subgeneric definition. New morphological characters including important secondary sexual characters and sexual dimorphism are described and male genitalia are illustrated for the first time for the type species of the subgenus, P. (G.) szechuanus (Chapin). A key to the six species is presented and the distribution of each species is documented and discussed.

Xylosandrus crassiusculus (Motchulsky) is a native Asian ambrosia beetle that has been accidentally introduced to many countries of the world, presumably through the international movement of nursery, timber, and wood products. The species is known in various tropical African countries but only as far south as Tanzania on the African continent. In this study, we report X. crassiusculus and its fungal symbiont for the first time from South Africa. The species was identified using both morphological characters and COI sequence data. Xylosandrus crassiusculus were obtained from three different provinces of South Africa and represent two distinct haplotypes. The fungal symbiont, Ambrosiella roeperi, was isolated and identified using DNA sequencing and morphological characterization.

The Australian Stephanidae (Hymenoptera) are revised and keyed. Three genera and 21 species (15 new) are recognised. The taxonomic importance of over 300 morphological characters, including 45 morphometric ratios, is assessed. The history of introduction and establishment of Schlettererius cinctipes in Australia is summarised. Stephanus crassicauda Morley is transferred to Megischus, the female is redescribed and the male is reported for the first time and compared with the female. Occurrence of the Neotropical genus Hemistephanus in Australia is refuted and M. giganteus (Girault) is synonymised with M. crassicauda (Morley). The groundplan of Australian Parastephanellus is described in detail and a new character set is proposed for taxonomic studies and descriptions of its species, P. albiceps Elliott is proposed as a junior synonym of P. damellicus (Westwood) and P. picticeps Roman is placed as species inquirendum. New taxa are Megischus ceneonatrix, Parastephanellus albigenuis, P. adiazetos, P. brevis, P. callidictyon, P. denotatus, P. isoglyptos, P. laevigatus, P. maculatus, P. platyceratus, P. squamatus, P. strigosus, P. tanytarsus, P. trifasciatus and P. vertipictus. Other valid species from Australia are P. caudatus Elliott and P. rufoornatus (Cameron).

Matthiola spathulata Conti (1900: 49) was described as a new species in the first monograph of the genus. Apart from the type, which was collected from Iran, no other collections of the species have ever been recorded in the literature (Chernyakovskaya 1939; Cullen 1965; Rechinger 1968; Townsend 1980; Gowler 1998). During a revision of Matthiola W.T.Aiton for the Flora of Iran and neighboring countries, the authors studied many specimens of the genus from NW Iran and southern Armenia that fit the description and type of M. spathulata. Then, in the process of taxonomic studies of this genus, we found that M. iranica Zeraatkar et al. (2016: 145) and M. odoratissima var. dentata Boissier (1867: 149) are conspecific with M. spathulata. The slight differences in leaf morphology, noted in the description of M. odoratissima var. dentata, occurs sometimes throughout most of the range of M. spathulata. Rechinger (1968: 234) considered that M. odoratissima var. dentata and M. farinosa Bunge ex Boissier (1867: 150) as conspecific and cited the type gathering of the former among the studied material of the latter, but no formal synonymy has been proposed by him. Matthiola spathulata is closely related to M. odoratissima W.T.Aiton (1812: 120) but differs in its entire leaves, longer petals, pedicels and fruits (Figs. 1 & 2 M–N; see below). The former is quite different from M. odoratissima in morphological characters and distribution patterns. Matthiola spathulata is distributed in NW Iran and southern Armenia. By contrast, M. odoratissima is mostly distributed along the Black Sea coast (Fig. 2O). Finally, M. spathulata was previously known only from one locality in Iran and is recorded herein for the first time from Armenia.

A New Species

The supraspecific taxonomy of the coastal carabid Bembidion (‘Cillenus’) complex is controversial because a single ‘synapomorphy,’ a large head with long mandibles, may be the result of functional convergence. This study examined the phylogeny of B. (‘Cillenus’) complex based on morphological characters to revise the complicated taxonomy of this group. All type species of the genera concerned were included, and membranous parts of the genitalia (male endophallus and female vagina and spermatheca) were examined for the first time. Because all species are treated under the genus Bembidion Latreille (s. l.), Bembidion umi nom. nov. is proposed as a new name for Sakagutia marina Uéno. In the resultant tree, reciprocal monophyly of most traditional taxa was not supported, whereas a monophyletic group of the following seven species was relatively well supported: B. seticorne Lindroth, B. yokohamae (Bates), B. sumaoi Morita, B. aestuarii (Uéno & Habu), B. tokunoshimanum (Nakane), B. tsutsuii (Uéno), and B. yakushimanum sp. nov. Based on these results, the subgenus Desarmatocillenus Netolitzky (type species: B. yokohamae) was redefined, and two subgenera were synonymised with it: Novicillenus Uéno & Habu (type species: B. aestuarii) syn. nov., and Corallicillenus Uéno (type species: B. tsutsuii) syn. nov.. Bembidion (Desarmatocillenus) yakushimanum sp. nov. is described from Japan.
