Eleven Species

The Old World genus Mesocomys Cameron (1905) (Hymenoptera: Eupelmidae: Eupelminae) is revised. Eleven species, including two newly described species, are recognized and keyed in two previously established species groups, the albitarsis and the pulchriceps species groups sensu Gibson (1995), but with additional features provided to distinguish members of the two groups. Five species are recognized in the pulchriceps group—Mesocomys anelliformis n. sp., M. longiscapus n. sp., M. orientalis Ferrière, 1935, M. pauliani Ferrière, 1951, and M. pulchriceps Cameron, 1905. Seven species are assigned to the albitarsis group, but one, M. aegeriae Sheng, 1996 is treated as a nomen dubium; the six recognized and keyed species in the albitarsis group are M. albitarsis (Ashmead, 1904), M. breviscapis Yao, Yang & Zhao, 2009, M. menzeli (Ferrière, 1930b), M. obscurus (Ferrière, 1930b) revised stat., M. superansi Yao, Yang & Zhao, 2009, and M. trabalae Yao, Yang & Zhao, 2009. Within the albitarsis group, the species are further discussed relative to two newly established species subgroups, the albitarsis subgroup for M. albitarsis, M. menzeli and M. obscurus, and the aegeriae subgroup for M. aegeriae, M. breviscapis, M. superansi and M. trabalae. Females of the albitarsis subgroup possess a finely sculptured mesoscutal medial lobe in combination with partly infuscate fore wings and/or at least partly pale flagellum, whereas females of the aegeriae subgroup possess a much more coarsely sculptured mesoscutal medial lobe and hyaline fore wings in combination with a dark flagellum. Members of the albitarsis species group are restricted to the Oriental and eastern Palaearctic regions except for a single female of the aegeriae subgroup seen from Algeria that is provisionally identified as M. breviscapis; members of the pulchriceps group are restricted to the Afrotropical region except for M. orientalis from the Oriental region. Newly placed in synonymy are M. aegeriae Sheng, 1998 under M. aegeriae Sheng, 1996 n. syn., M. sinensis Yao, Yang & Zhao, 2009 under M. breviscapis Yao, Yang & Zhao, 2009 n. syn., M. atulyus Narendran, 1995 under M. orientalis Ferrière, 1935 n. syn., M. vuilleti (Crawford, 1912) under M. pulchriceps Cameron, 1905 n. syn., and Semianastatus orientalis Kalina, 1984 and Mesocomys kalinai Özdikmen, 2011 under M. albitarsis (Ashmead, 1904) n. syns. Lectotypes are newly designated for M. menzeli, M. obscurus, M. orientalis, M. pauliani, M. pulchriceps and M. vuilleti. Morphological features characteristic of the genus and of the highly dimorphic sexes are described and illustrated, and the species are keyed, described, and illustrated through macrophotography. Phylogenetics are discussed for the genus, the two species groups, and species within the pulchriceps group. Distribution and host records are also summarized for each species.

Species Groups

The taxonomy and systematics of the genus Digitonthophagus Balthasar (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) is revised. A detailed study of the male genitalia combined with external morphology suggests that the variability, previously recognized, for D. gazella is hiding a species complex within the Afrotropical region and the Arabian Peninsula. The current study recognizes 16 species; 13 from the Afrotropical region and Arabian Peninsula and three from the eastern portion of the Saharo-Arabian region and the continental Indomalayan region. Species are organized into six species groups based on the results of the morphology-based phylogenetic analysis. The following 12 species are described as new: D. aksumensis Génier new species; D. biflagellatus Génier new species; D. dilatatus Génier new species; D. eucatta Génier new species; D. falciger Génier new species; D. fimator Génier new species; D. namaquensis Génier new species; D. petilus Génier new species; D. sahelicus Moretto new species; D. uks Génier new species; D. ulcerosus Génier new species; and D. viridicollis Génier new species. In order to stabilize nomenclature, lectotypes are designated for Scarabaeus bonasus Fabricius, 1775; Scarabaeus catta Fabricius, 1787, and Onthophagus gazella lusinganus d’Orbigny. A neotype is designated for Scarabaeus dorcas Olivier, 1789 whose status and synonymy need to be altered in order to clarify the status of Scarabaeus gazella auctorum, the widely introduced species with economic importance. A naming scheme is presented for the sclerites of the internal sac. External and male genitalia are illustrated and distribution maps are provided for each species.

Loxosceles Heineken & Lowe, 1832 spiders are infamous for their medical importance, but a taxonomic picture of the genus is still far from complete. In this study, the Chilean species of Loxosceles are described and mapped. The males of Loxosceles surca Gertsch, 1967 and L. coquimbo Gertsch, 1967 are described for the first time. Three new species with narrow distributions are described from central and northern Chile: Loxosceles diaguita sp. nov. from the Antofagasta Region, L. pallalla sp. nov. from Coquimbo and L. vallenar sp. nov. from Atacama. The first two species are remarkable in their morphology and do not fit into any of Gertsch’s species groups, suggesting that Chile still harbours an undiscovered phylogenetic diversity of the genus. New distribution records for Loxosceles laeta (Nicolet, 1849) are provided throughout Chile.

This study reviews the taxonomy of the ant genus Nesomyrmex Wheeler, 1910 in the Afrotropical region. Previous revisionary studies are discussed and four species groups are proposed on the basis of external morphology. The N. angulatus group contains seven species that are widely distributed throughout the whole Afrotropical region, with one species also occurring in the Palaearctic and Malagasy regions. The N. cataulacoides group is monotypic, with one morphologically bizarre species found in Equatorial rain forests. The N. humerosus group is also monotypic and occurs in East Africa. The last and by far most species-rich group is the N. simoni group that contains 17 species, all of which are endemic to South Africa. The four groups are defined for the first time for the region, and an illustrated identification key is provided. Furthermore, the N. angulatus group is more thoroughly reviewed. One new species from Mozambique is described, N. inhaca sp. nov., and species accounts for the other six are provided. Also, an illustrated identification key to the species of the N. angulatus group is presented.

AbstractThe genus Cricotopus of the arctic zone of the Nearctic region, represented by 14 species in seven species groups, is reviewed. Descriptive notes on 11 species supplement those given by Hirvenoja (1973), with addition of descriptions of immature stages of C. lestralis (Edwards) and larva of C. tristis Hirvenoja. Two new species names, C. beringensis and C. trilobus, are proposed. New species names synonymies are Chironomus basalis Staeger and Chironomus holmgreni Kieffer with Chironomus tibialis (Meigen) (= C. tibialis). Several undetermined individuals are assigned to the fuscus group. Eleven species are Holarctic in distribution, of which C. bicinctus (Meigen) and C. sylvestris (Fabricius) are circumboreal. Seven species are restricted to the arctic zone, two are wide-ranging in both arctic and temperate zones, and four temperate species barely extend into the arctic zone. Keys to all known life-history stages and some ecological data, primarily of larvae, are given.

The present study represents an introduction to the revision of Pheidole Westwood, 1839 from Madagascar. Sixteen species groups are established, of which eleven are revised below, and illustrated identification keys to species groups and species of groups revised in this monograph are presented. Two species are raised to species level: Pheidole petax Forel, 1895 stat. nov., and P. scabrata Forel, 1895 stat. nov. We also redescribe worker castes and designate lectotypes for P. annemariae Forel, 1918, P. nemoralis Forel, 1892, P. petax Forel, 1895, P. ensifera Forel, 1897, P. longispinosa Forel, 1891, and P. scabrata Forel, 1895. The following 46 new species are described: Pheidole aelloeasp. nov., P. alasp. nov., P. andapasp. nov., P. ankeranasp. nov., P. avaratrasp. nov., P. bemarahaensissp. nov., P. bemarivoensissp. nov., P. binarasp. nov., P. boriborasp. nov., P. brevipilosasp. nov., P. curvistriatasp. nov., P. diakritossp. nov., P. ehazoarasp. nov., P. ferrugineasp. nov., P. fisakasp. nov., P. fitaratasp. nov., P. glabrasp. nov., P. goavanasp. nov., P. lamperossp. nov., P. longipilosasp. nov., P. luteasp. nov., P. madinikasp. nov., P. mahaboensissp. nov., P. maizinasp. nov., P. makaensissp. nov., P. makirovanasp. nov., P. manantenensissp. nov., P. mantadiasp. nov., P. marieannaesp. nov., P. masoalasp. nov., P. mavesatrasp. nov., P. miramilasp. nov., P. moramanaensissp. nov., P. navoatrensissp. nov., P. ocypodeasp. nov., P. parvioculasp. nov., P. podargeasp. nov., P. praegrandissp. nov., P. ranohirensissp. nov., P. rugocephalasp. nov., P. rugofitaratasp. nov., P. typhlossp. nov., P. vatovavensissp. nov., P. voasarasp. nov., P. vohemarensissp. nov., and P. zavamanirasp. nov. At present, there are 69 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase significantly with upcoming taxonomic revisions of the species groups not revised in this study.

Taxonomic Studies

Psychotria subg. Heteropsychotria Steyerm. has been shown by morphological and molecular analyses to be polyphyletic. Most of its species, including its type, belong to Palicourea Aubl. (“Pal.”). Thirty-two species of this group are reviewed here, and 17 species in Psychotria L. are transferred to Palicourea and one to Rudgea Salisb. Two replacement names, Pal. agudeloana C. M. Taylor and Pal. tabayensis C. M. Taylor, are published. Taxonomic studies here clarify circumscriptions of similar, often-confused species for several distinctive species groups found variously in Mesoamerica and the Andes: the Palicourea aschersonianoides group, the Palicourea galeottiana group, the Palicourea sulphurea group, and the Palicourea tristis group. Three new species of Palicourea are described: Pal. aschersonianula C. M. Taylor, Pal. gonzaleziana C. M. Taylor, and Pal. wachterae C. M. Taylor. Nineteen names are newly typified, and infrageneric classifications are noted for the species of Palicourea studied.
