An analysis of species-groups of the genus Plinthisus Stephens (Hemiptera: Rhyparochromidae) in the Ethiopian Region with the description of eight new species

An analysis of the known Ethiopian Plinthisus fauna shows that there are at least 12 species-groups. Two groups, the subgenera Locutius and Isioscytus, have Old World Palearctic and tropicopolitan distributions that extend into Australia. The other 10 species-groups are endemic to Africa, nine having a center of endemicity in the Cape Region of South Africa with apparent relationships to the Australian fauna. Eight new species of Plinthisus are described, each as a representative of a distinct species-group, seven from South Africa: P. (Isioscytus) pulchellus n. sp, P. (Nanoplinthisus) ericae n. sp, P. (N.) fynbosi n. sp, P. (N.) peninsularis n. sp., P. (N.) lamprus n. sp., P. (N) zuurb- ergi n. sp., and P. (N.) drakensbergensis n. sp,; and one, P. (Plinthisus) brachyoccus n. sp., from the Democratic Republic of the Congo. P. beniamaricus Linnavuori, 1978 stat. nov. and P. kilimensis Horv th, 1906 stat. nov. are raised from subspecies of P. himyaritus Linnavuori, 1978 and P.afer Horv th, 1906, respectively to specific rank. Plinthisus hirsutus Slater, 1964 is placed in a species-group distinct from the subgenus Dasythisus. The Nearctic species Plinthisus americanus Van Duzee, 1910, P. compactus Uhler, 1904 and P. indentatus Barber, 1918 are placed in the subgenus Dasythisus. Included are 123 figures illustrating dorsal views, heads, metathoracic scent gland areas, metathoracic wing stridulitra, abdominal structure, male genital capsules, claspers, phalli, spermathecae, and prothoracic legs.

First Time

The genus Drassodella Hewitt, 1916 is one of four Afrotropical genera of Gallieniellidae, and is presently represented by seven species, all endemic to South Africa. The type material of six of the described species was studied and they are redescribed from both sexes: D. melana Tucker, 1923, D. quinquelabecula Tucker, 1923, D. salisburyi Hewitt, 1916, D. septemmaculata (Strand, 1909), D. tenebrosa Lawrence, 1938 and D. vasivulva Tucker, 1923. Of these, the males of D. melana, D. tenebrosa and D. vasivulva are described for the first time. Recent field work yielded additional females of D. purcelli Tucker, 1923 from the vicinity of the type locality, and this sex is redescribed; the male remains unknown. A further 12 new species are recognized: D. amatola sp. nov. (♀ ♂), D. aurostriata sp. nov. (♀ ♂), D. baviaans sp. nov. (♂), D. flava sp. nov. (♀ ♂), D. guttata sp. nov. (♀ ♂), D. lotzi sp. nov. (♀), D. maculata sp. nov. (♀), D. montana sp. nov. (♀ ♂), D. tolkieni sp. nov. (♀ ♂), D. trilineata sp. nov. (♀), D. transversa sp. nov. (♀ ♂) and D. venda sp. nov. (♀ ♂). Based on the genitalic structures, there appear to be two distinct species groups. The D. melana species group, which includes D. melana, D. tenebrosa and eight new species mainly distributed in eastern and northern South Africa, is characterised by very conservative genitalic morphology in both sexes. The D. salisburyi species group, with considerable variation in the structure of the copulatory organs and distributed in the southern half of South Africa, includes the remaining nine species, of which four are new. Although D. tenebrosa represents an intermediate between the two groups, with palpal morphology more typical of the D. melana species group and epigynal morphology typical of the D. salisburyi group, it is placed in the former species group based on its distribution in eastern South Africa. The biology, habitat preferences and biogeography of Drassodella are briefly discussed.

First Time

Three new species groups and seven species of the genus Pediobius Walker are described from the Afrotropical realm: the marjoriae group, with P. marjoriae Kerrich (described from Uganda), P. rohombaya Gumovsky sp. n. (from the Central African Republic (CAR), the Democratic Republic of the Congo (DRC), Gabon, Uganda) and P. orungu Gumovsky sp. n. (from Gabon); the afroteres group with P. afroteres Gumovsky sp. n. (from South Africa, Zimbabwe, Malawi, Kenya, Uganda, DRC, Cameroon) and P. kafroteres Gumovsky sp. n. (from Cameroon); the askari group with P. askari Gumovsky sp. n. (from South Africa, Zimbabwe, Kenya, Tanzania, DRC, Ivory Coast) and P. maleficus Gumovsky sp. n. (from Kenya, DRC, CAR, Cameroon, Gabon); and P. nganga Gumovsky sp. n. (from DRC) (not assigned to any group). All these species are characterized by the relatively wide and robust head with elongate and/or narrowed lower face and the antennae attached near or below the lower eye margins. Morphological features of the species, as well as their habitat distribution, are discussed. The comparison of the new species with similar taxa of Entedoninae suggested the following synonymies: Rhynchentedon Girault and Pediobomyia Girault under Pediobius (syn. n.); Bomyiabius frontus Narendran, Pediobomyia budaicus Narendran and Pediobomyia lankicus Narendran under Pediobomyia darwini Girault (syn. n.). The following new combinations are proposed: Pediobius maximus (Girault), P. achterbergi (Gumovsky), P. narendrani (Gumovsky), P. brevicaulis (Hansson), P. canaliculatus (Hansson) and P. darwini (Girault) (comb. n.). Ant parasitoids P. marjoriae and Myrmokata diparoides Bouček are recorded from DRC for the first time.

Ethiopian Region

The genus Canthyporus Zimmermann, 1919, is revised. A total of 35 species are recognized, all of them distributed within the Ethiopian Region, and with a centre of diversity in the South African Western Cape province. Descriptions of all species are given together with illustrations of habitus and male and female genitalia. A key to species (males), distribution maps, and ecological information are provided. Four new species are described from South Africa: Canthyporus aenigmaticus n.sp., C. nimius n.sp., C. turneri n.sp., and C. wewalkai n.sp. The species C. congener Omer-Cooper, 1956, is regarded as valid and not as a junior synonym of C. canthydroides (Régimbart, 1895). Lectotypes are designated for the following ten names: C. alvei Omer-Cooper, 1965, C. consuetus Omer-Cooper, 1965, C. latus Omer-Cooper, 1965, C. lowryi Omer-Cooper, 1965, C. nebulosus Omer-Cooper, 1965, C. similator Zimmermann, 1923, C. simulator Guignot, 1959, C. testaceus Zimmermann, 1923, Hydroporus collaris Boheman, 1848, and Hydroporus hottentottus Gemminger & Harold, 1868. A parsimony analysis based on 32 morphological characters found 28 shortest trees. Monophyly of the genus Canthyporus is supported mainly by the presence of an anterior ligula on the ventral side of the elytron. Four species groups are recognized within the genus: (1) canthydroides group, including ten species in Namibia and South Africa; (2) exilis group, including four species in Lesotho and South Africa; (3) hottentottus group, including 18 species from the Democratic Republic of the Congo, Ethiopia, Kenya, Lesotho, Madagascar, South Africa, Swaziland, Tanzania, and Zimbabwe; and (4) lateralis group, including three species from South Africa.

AbstractEpicypta is treated in the sense employed by Edwards (1925) under the name Delopsis Skuse. The species of Epicypta in the Holarctic region are discussed and keyed. Type material of Mycetophila aterrima Zett., M. selecta Walker, M. vitrea Coquillett and Epicypta pulicaria Loew has been examined and found to be conspecific. Lectotypes are designated for aterrima, vitrea and pulicaria. Mycetophila anomala Johannsen (holotype examined) is a distinct species but a new name, limnophila nom.n. is proposed as it is a homonym. Both aterrima and limnophila are Holarctic. Four other European species, scatophora (Perris), fumigata (Dziedzicki), torquata Matile and nigrobasis (Dziedzicki) (last not examined) are recognised. These six species and the Japanese ornatipennis (Okada) (not examined) belong to one species group related to Oriental and Afrotropical species. Two new species, lepida n.sp. and helvopicta n.sp., described from north America, belong to different, otherwise Neotropical, species groups. Descriptions and figures are given for all species known from the Holarctic, except nigrobasis and ornatipennis.

Tropical South America

The giant water bug fauna from tropical South America remains poorly known. Three species of Belostoma Latreille (Belostoma fittkaui De Carlo, B. sayagoi De Carlo and B. hirsutum Roback & Nieser) have been cited only a few times in the literature. These three species are remarkable since they represent an extreme variation for the genus, with article II of the labium distinctly shorter than article III. Here, the synonymy of B. hirsutum with B. sayagoi is proposed based on examination of type material and additional specimens. Further, B. fittkaui and B. sayagoi are redescribed, including discussion about comparative morphology with congeners. A new species group is proposed for these species and a key to the Belostoma species groups is provided. Distribution records are also updated.
