A New Species

Seven new species of Brazilian Euplocania are described and illustrated, five species belong in the amabilis species group (Euplocania bujariensis n. sp., Euplocania cearaensis n. sp., Euplocania hutchingsi n. sp., Euplocania pseudopictaoides n. sp. and Euplocania xavieri n. sp.) one species belong in the marginata species group (Euplocania uariniensis n. sp.) and one species is not assignable to any of the known species groups of the genus. For this species, E. quinquedivisa n. sp., a new species group is here diagnosed, the quinquedivisa group. Information on sexes known and distribution is included for all known species of Euplocania. The first identification key to males of Euplocania species from Brazil is presented.

A New Species

For the recently established genus Madagopsina (Diopsidae, stalk-eyed flies), Madagopsina makayensis Feijen, Feijen & Feijen, sp. nov. is described from Madagascar. A concise catalogue is given for the genus and an identification key is presented for its six species. The differential character states are listed for the two species groups of the genus: the Madagopsina apollo species group and the Madagopsina apographica species group. The intrageneric relations are discussed based on morphology, geometric morphometrics analysis of wing shape, and allometric data for eye span against body length. Each of these three procedures places the new species in the M. apollo species group with Madagopsina parvapollina as its closest relative. New records are presented for M. apographica and M. parvapollina.

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.

Pselaphogenius chloe sp. n. belonging to the fiorii species group is described. The distribution of the 12 species belonging to this group is detailed and an identification key is provided. The hypothesis that the current distribution and the differentiation of the species of the Pselaphogenius of the fiorii group have been determined by the Pleistocenic glaciations is discussed.

A New Species

A new species, Baetis pentaphyllus sp. nov., is described on the basis of larvae from the Far East of Russia (type locality Bolshoi Garmakan River). Larvae of Baetis pentaphyllus sp. nov. may be distinguished from other Baetis species by the presence of only five pairs of tergalii on segments III–VII. The mitochondrial COI sequence obtained from the described species was compared with the data present in GeneBank and BOLD. The DNA barcodes allowed discrimination of B. pentaphyllus sp. nov. from other species of Baetis with available sequence data. The average interspecific K2P distances were 10–15%, which are values well above those associated with intraspecific variation. COI sequences as well as 36 morphological larval characters were analysed using Bayesian inference to relate the described species to the recognized species-groups of the Baetis genus. B. pentaphyllus sp. nov formed a sister clade to B. vardarensis + B. lutheri which belong to the Baetis lutheri species-group.

Trechodes intermedia sp. nov. and T. kogelbergensis sp. nov. are described from South Africa. A third species, T. humeralis (Jeannel, 1930) comb.nov. is transferred to Trechosia Jeannel from the genus Cothresia Jeannel. All three species are macropterous, endemic to the South African Cape region, and together represent a new species group of the genus Trechosia. Keys to the species groups of the genus Trechosia and to the species of the new T. intermedia group are provided.

Single Locality

Drapetis is a genus of tiny predaceous hybotid flies found frequently on the bark of trees. From a single locality in province Skåne (S Sweden) we report the co-existence of seven species of Drapetis. One is new and described as D. abrollensis sp. nov., and four species, D. assimilis (Fallén), D. completa Kovalev, D. infitialis Collin and D. stackelbergi Kovalev, are relatively recent additions to the list of Swedish Diptera. A key to males of the 14 species of Drapetis known from NW Europe is given. Special emphasis is given to modifications of the midleg cuticle observed in males of several species that belong to the D. exilis-species group. As shown by SEM images these modifications differ greatly between the species, both at light microscopic and ultrastructural levels. These modifications are introduced as a new set of characters in the identification key. Finally, brochosomes were detected on the midleg of three SEM-examined Drapetis species, documenting indirectly that small leafhoppers are regularly used as prey.

A New Species

AbstractA revised diagnosis of the genus Saldula Van Duzee based upon synapomorphic characters of male genitalia and hemelytral pigmentation patterns is given. According to this concept ca. 55% of the species World-wide currently assigned to Saldula will have to be transferred to other genera. Several new characters are employed in the definition of species and species groups. The species attributable to the pallipes species group are listed and supplemented by a brief overview of the taxonomic relationships of the Old World species. Saldula luteola sp. n. is described from coastal salt marshes on the Island of Djerba, Tunisia. It mainly appears in extremely depigmented morphs unparalleled elsewhere in the Saldidae and likely constitutes a sister-species of S. sardoa Filippi. The conspicuous intraspecific variation in body size and hemelytral pigmentation in S. palustris (Douglas), the closest relative of the former species, is depicted and briefly discussed. The descriptive accounts are accompanied by numerous photographic illustrations of somatic and genital characters.

The present study represents a taxonomic revision of the Pheidole sikorae species group from Madagascar. Forty-four members of this group are recognised and described, and an illustrated identification key to this group is also presented. One species is raised to species level: P. litigiosa Forel, 1892 stat. nov.Pheidole veteratrix angustinoda Forel, 1892 syn. nov. is proposed as a junior synonym of Pheidole veteratrix Forel, 1891. Worker castes are also described and lectotypes designated for P. litigiosa Forel, 1892, P. sikorae Forel, 1891, and P. veteratrix Forel, 1891. The following 41 new species are described: P. alinasp. nov., P. ambohimangasp. nov., P. analavelonasp. nov., P. andohahelasp. nov., P. anomalasp. nov., P. anosyennesp. nov., P. antranohofasp. nov., P. beankasp. nov., P. befotakasp. nov., P. dasossp. nov., P. flavominutasp. nov., P. gracilissp. nov., P. habokasp. nov., P. havoanasp. nov., P. hazosp. nov., P. itremosp. nov., P. joffrevillesp. nov., P. kelysp. nov., P. lavasoasp. nov., P. mahamavosp. nov., P. maintysp. nov., P. mamiratrasp. nov., P. mananteninasp. nov., P. masoandrosp. nov., P. mavohavoanasp. nov., P. midongysp. nov., P. mikrossp. nov., P. mivorysp. nov., P. nitidobrunasp. nov., P. parvulasp. nov., P. parvulogibbasp. nov., P. reniranosp. nov., P. savasp. nov., P. sofiasp. nov., P. sparsasp. nov., P. tamponysp. nov., P. trichotossp. nov., P. tsaravonianasp. nov., P. vadumsp. nov., P. volontanysp. nov., and P. vonysp. nov. At present, there are 109 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase with upcoming taxonomic revisions of the species groups not revised in this study.
