Some observations on the distribution and life history of Caenis robusta Eaton (Ephemeroptera) in Cheshire and North Shropshire,England

Caenis robusta Etn. was found in only 8 of 107 water bodies sampled. All the habitats from which it was recorded contained plant debris; the waters were still or slow-flowing and had conductivities ranging from 120–687 µmhos cm^–1 at 25°C.In North Shropshire, England, C. robusta had one generation per year. Newly hatched nymphs were abundant in August and growth occurred rapidly until September. No growth took place from October until March but was again rapid from April until June. Emergence took place at dusk in late June and July.     

Taxonomic revision of the genus Carasobarbus Karaman, 1971 (Actinopterygii,Cyprinidae)

Representatives of the fish genus Carasobarbus Karaman, 1971 (Actinopterygii: Cyprinidae) from the Middle East and North Africa were previously placed in 14 different genus-group taxa (Barbellion, Barbus, Barynotus, Capoeta, Carasobarbus, Cyclocheilichthys, Kosswigobarbus, Labeobarbus, Luciobarbus, Pseudotor, Puntius, Systomus, Tor and Varicorhinus). The generic assignment of several species changed frequently, necessitating a re-evaluation of their taxonomic status. In this study, the genus Carasobarbus is revised based on comparative morphological examinations of about 1300 preserved specimens from collections of several museums and freshly collected material. The species Carasobarbus apoensis, Carasobarbus canis, Carasobarbus chantrei, Carasobarbus exulatus, Carasobarbus fritschii, Carasobarbus harterti, Carasobarbus kosswigi, Carasobarbus luteus and Carasobarbus sublimus form a monophyletic group that shares the following combination of characters: medium-sized barbels with a smooth last unbranched dorsal-fin ray, nine or 10 branched dorsal-fin rays and six branched anal fin-rays; scales large, shield-shaped, with many parallel radii; the lateral line containing 25 to 39 scales; the pharyngeal teeth hooked, 2.3.5-5.3.2 or 2.3.4-4.3.2; one or two pairs of barbels. The species are described in detail, their taxonomic status is re-evaluated and an identification key is provided. A lectotype of Systomus luteus Heckel, 1843 is designated. Carasobarbus Karaman, 1971, Kosswigobarbus Karaman, 1971, and Pseudotor Karaman, 1971 are subjective synonyms, and acting as First Reviser we gave precedence to the name Carasobarbus.     

Taxonomic revision of the subfamily Toradjiinae (Crustacea: Oniscidea: Scleropactidae)

In the present revision four genera and 32 species are recognized. One genus, Paratoradjia , and 17 species, namely Adinda malaccensis, A. sumatrana, A. palniensis, A. carli, A. nilgiriensis, A. lobata, A. triangulifera, A. rudeli, A. lamellata, Protoradjia paeninsulae, P. insularis, P. montana, P. pilosa, Paratoradjia beroni, P. vietnamensis, P. sulcata and Toradjia hirsute , are described as new. The neotype of Toradjia cephalka and lectotypes of Adinda weberi, Protoradjia jacobsoni, Toradjia gorgona and T. celebensis are established. Adinda cahgarii is considered to be a junior synonym of Adinda weberi , and A. conglobator , a species inquirenda. Toradjia dollfusi is transferred to the genus Adinda , and T. indosinensis to Paratoradjia. The characters of the group and its taxonomic position within the Oniscidea are discussed: it is transferred from the Eubelidae to the Scleropactidae, of which it constitutes a separate subfamily, the Toradjiinae. A map and comments on the distribution of genera and species are included.     

Taxonomic notes on the genus Syndiamesa Kieffer (Diptera: Chironomidae) from Japan, with description of a new species

The Japanese species of the genus Syndiamesa are revised. A new species, Syndiamesa longipilosa sp. nov., from Honshu, Japan is described from male and female material. The male of Syndiamesa mira (Makarchenko) from Japan is redescribed and figured. Syndiamesa chuzemagna Sasa is synonymized with Syndiamesa yosiii Tokunaga. Syndiamesa bicolor Tokunaga is transferred to the genus Sympotthastia. A key to males of Japanese Syndiamesa is provided.     

Taxonomy, distribution and nesting biology of species of the genus Dolichovespula (Hymenoptera, Vespidae)

The genus Dolichovespula consists provisionally of 18 species. Aerial nest site characteristics have been established for seven species but most of these species show flexibility in their choice of nest sites and two species often nest in shallow subterranean situations. Colony length is usually just over 3 months to approximately 4 months, but at lower latitudes may extend to more than 5 months. Mature colony size is usually approximately 1000 cells with more large cells than small cells. Parasitized colonies have a shorter colony cycle and smaller colonies. During the production of the sexual brood the larva/worker ratio reaches its lowest value of approximately 2.5 larvae per worker. Colonies often have upper mixed combs of small and large cells. Total adult production is usually less than 2000 adults. Colonies of D. arenaria and D. norwegica may specialize in mainly producing males or queens. Variations in mature colony size and production of queens is probably a consequence of the number of workers present, particularly early in the colony cycle.     

Factors affecting the distribution and abundance of Cloeon and Caenis (Ephemeroptera) larvae in a tropical impounded river, Nigeria

Impoundment of rivers affects the mayfly (Ephemeroptera) fauna inhabiting such water bodies, especially with respect to their distribution and abundance. A two‐year study of the mayfly fauna and some of the physicochemical parameters of the Opa stream–reservoir revealed that there are two mayfly genera inhabiting it, Cloeon and Caenis. The number of Cloeon larvae collected was 10,930 while the number of Caenis larvae was 450. It was observed that although both genera occurred at all the sampling stations, their numbers were reduced in the stream below the dam due to increased water current velocity. There were significant differences in the abundance of Cloeon among the stations, but none for Caenis. Submerged aquatic plants and water current velocity were found to be the major factors responsible for the significant differences. There were significant correlations between the number of Cloeon larvae and pH as well as between dissolved oxygen concentration and Caenis. These findings are discussed with reference to inter‐specific differences in patterns of response to environmental parameters. A species‐specific approach is suggested for studies on the strategies that enable mayfly species maintain their populations in stressed and unstable aquatic ecosystems.     

Taxonomic, nomenclatural and chorological notes on several taxa of the genus Echinodorus (Alismataceae)

Taxonomic, nomenclatural and chorological notes on several taxa of the genus Echinodorus are given. A new species E. maculatus is described. The name Alisma intermedium (basionym of the name E. intermedius) is lectotypified. Echinodorus major and E. martii should be treated as two distinct taxa. The name E. xinguensis was invalidly published. It is also confirmed that E. africanus, E. veronikae and E. viridis (all belonging to the E. uruguayensis group) do not originate from Africa. The name E. bleherae should be written with a female suffix (-ae); this name is considered here as a synonym of the earlier name E. grisebachii.     

Taxonomic notes on the genus Strongylopsalis Burr (Dermaptera: Labiidae)

The male and female of a new species of Strongylopsalis are described from Bolivia. Carcinophora boliviana Bormans is redescribed, and its position in the genus Strongylopsalis is confirmed; a new name is proposed for S.boliviana Brindle. A key is given to the ten species now contained in Strongylopsalis, and notes on the distribution of the genus and its possible relationship to Marava are included.     

Taxonomic revision of the tarantula genus Aphonopelma Pocock, 1901 (Araneae,Mygalomorphae, Theraphosidae) within the United States

This systematic study documents the taxonomy, diversity, and distribution of the tarantula spider genus Aphonopelma Pocock, 1901 within the United States. By employing phylogenomic, morphological, and geospatial data, we evaluated all 55 nominal species in the United States to examine the evolutionary history of Aphonopelma and the group’s taxonomy by implementing an integrative approach to species delimitation. Based on our analyses, we now recognize only 29 distinct species in the United States. We propose 33 new synonymies (Aphonopelma apacheum, Aphonopelma minchi, Aphonopelma rothi, Aphonopelma schmidti, Aphonopelma stahnkei = Aphonopelma chalcodes; Aphonopelma arnoldi = Aphonopelma armada; Aphonopelma behlei, Aphonopelma vogelae = Aphonopelma marxi; Aphonopelma breenei = Aphonopelma anax; Aphonopelma chambersi, Aphonopelma clarum, Aphonopelma cryptethum, Aphonopelma sandersoni, Aphonopelma sullivani = Aphonopelma eutylenum; Aphonopelma clarki, Aphonopelma coloradanum, Aphonopelma echinum, Aphonopelma gurleyi, Aphonopelma harlingenum, Aphonopelma odelli, Aphonopelma waconum, Aphonopelma wichitanum = Aphonopelma hentzi; Aphonopelma heterops = Aphonopelma moderatum; Aphonopelma jungi, Aphonopelma punzoi = Aphonopelma vorhiesi; Aphonopelma brunnius, Aphonopelma chamberlini, Aphonopelma iviei, Aphonopelma lithodomum, Aphonopelma smithi, Aphonopelma zionis = Aphonopelma iodius; Aphonopelma phanum, Aphonopelma reversum = Aphonopelma steindachneri), 14 new species (Aphonopelma atomicum sp. n., Aphonopelma catalina sp. n., Aphonopelma chiricahua sp. n., Aphonopelma icenoglei sp. n., Aphonopelma johnnycashi sp. n., Aphonopelma madera sp. n., Aphonopelma mareki sp. n., Aphonopelma moellendorfi sp. n., Aphonopelma parvum sp. n., Aphonopelma peloncillo sp. n., Aphonopelma prenticei sp. n., Aphonopelma saguaro sp. n., Aphonopelma superstitionense sp. n., and Aphonopelma xwalxwal sp. n.), and seven nomina dubia (Aphonopelma baergi, Aphonopelma cratium, Aphonopelma hollyi, Aphonopelma mordax, Aphonopelma radinum, Aphonopelma rusticum, Aphonopelma texense). Our proposed species tree based on Anchored Enrichment data delimits five major lineages: a monotypic group confined to California, a western group, an eastern group, a group primarily distributed in high-elevation areas, and a group that comprises several miniaturized species. Multiple species are distributed throughout two biodiversity hotspots in the United States (i.e., California Floristic Province and Madrean Pine-Oak Woodlands). Keys are provided for identification of both males and females. By conducting the most comprehensive sampling of a single theraphosid genus to date, this research significantly broadens the scope of prior molecular and morphological investigations, finally bringing a modern understanding of species delimitation in this dynamic and charismatic group of spiders.     

Taxonomic revision of genus Ablattaria Reitter (Coleoptera,Silphidae) using geometric morphometrics

The genus Ablattaria Reitter, 1884 (Coleoptera: Silphidae: Silphinae) is revised. Four taxa are recognized as valid species: Ablattariaarenaria (Kraatz, 1876), Ablattariacribrata (Ménétries, 1832), Ablattarialaevigata (Fabricius, 1775) and Ablattariasubtriangula Reitter, 1905. Ablattarialaevigatavar.meridionalis Ganglbauer, 1899 is newly treated as a junior subjective synonym of Ablattarialaevigata. Lectotypes are designated for Phosphugaarenaria Kraatz, 1876, Ablattariaarenariavar.punctigera Reitter, 1884, Ablattariaarenariavar.alleoni Portevin, 1926, Silphacribrata Ménétries, 1832, Silphalaevigata Fabricius, 1775, Silphagibba Brullé, 1832, Ablattariagibbavar.costulata Portevin, 1926, Ablattariagibbavar.distinguenda Portevin, 1926, Ablattariagibbavar.punctata Portevin, 1926 and Ablattariasubtriangula Reitter, 1905. The distribution of all taxa is mapped, based on material examined. Geometric morphometric methods were used to evaluate shape variability in Ablattaria. Results indicated sexual dimorphism in all species. Shape inconsistency was found between the sexes of all taxa when tested independently. The first two relative warp axes indicated 65.17% shape variation in males and 65.72% in females. Canonical variate analysis separated the taxa studied. There was minimal overlap between some groups in both sexes. Differences in body shape between populations of Ablattarialaevigata from Central Europe, Italy and Greece + Turkey were also examined. Relative warps implied 58.01% shape variability on both axes in males and 64.78% in females. CVA revealed noticeable overlaps between the groups, although the Italian population demonstrated a higher separation in both sexes.     

Taxonomic study of the genus Neurotettix Matsumura (Hemiptera, Cicadellidae, Deltocephalinae) with a description of a new species from China

This paper treats all four known species of the genus Neurotettix Matsumura, 1914 (Hemiptera, Cicadellidae, Deltocephalinae), including one new species: Neurotettix truncatussp. n. from China. A key is given to distinguish all species of the genus, and illustrations of genitalia are provided.     

Taxonomic and evolutionary relationships in the genus Vella L. (Cruciferae)

Thirty-two differential characters are numerically analysed for the six existing taxa of the genus Vella L. The closely related monotypic genus Boleum Desv. is also included for comparison. Most of the characters used are morphological, but cariological, ecological and biogeographical aspects have also been studied. The results indicate that four distinct species, one ( V. pseudocytisus L.) with three sub-species, should be distinguished. The new combination V. anremerica (Lit. et Maire) Gómez-Campo (basionym: V. pseudocytisus L. subsp. anremerica Lit. et Maire) and the new name V. pseudocytisus L. subsp. paui Gómez-Campo for V. pseudocytisus L. var. glabrescens Willk., nornen nudum are presented. A key is given to aid identification of these taxa. Their conservation status is also discussed.
