Although studies on ostracods dwelling in inland subterranean habitats of Italy have increased in the last decades, highlighting a considerable taxonomic diversity, available information is still far from sufficient to understand phylogenetic and biogeographic relationships. Mixtacandona Klie 1938 is one of the most common and diverse genera of ostracods in subterranean waters. Of the 20 living recognized species in the genus, all stygobiontic and restricted to the Palearctic Region, four are known for the Italian peninsula and Sardinia, one of which exclusively as fossil. Several other Recent and fossil taxa attributable to Mixtacandona, but identified at supraspecific level, have been reported from various Italian regions. Here we report Mixtacandona idrisi n. sp., collected in a cave near Palermo, the first cavernicolous ostracod from the island of Sicily; in addition, the description of material recently collected in northern Italy, consisting of M. laisi and of a putative new species that has been tentatively allocated to the same genus, is given. Mixtacandona (Trapezicandona) italica Karanovic & Pesce, 2000 is tentatively treated as a junior synonym of M. talianae Gliozzi & Mazzini, 1998. The validity of species-groups within Mixtacandona is discussed. Relying on the results of this study, the authors argue for the need of a comprehensive revision of the genus.

In the Palearctic region, the hydraenid subgenus Asiobates Thomson, 1859 comprises two species groups (Jäch, 1990): the O. minimus Fabricius group and the O. bicolon Germar group. The O. bicolon group is quite diverse in the Iberian Peninsula (12 species) displaying a high level of endemism (six Iberian endemic species). In contrast, only two Iberian species of the O. minimus group are known to date, with both rather widely distributed in the western Palearctic Region: O. (Asiobates) aeneus Stephens, 1835 and O. (A.) minimus (Fabricius, 1792). A new species, apparently endemic to the northwestern Iberian Peninsula, is now added to this group.

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.

A New Species

Dichagyris is a diverse genus with a Holarctic distribution. Only a few taxa of the subgenus Albocosta Fibiger & Lafontaine, 1997 occur in the northwesternmost part of the Oriental region. The genus is most diverse in Turkey, Iran and the Central Asiatic high mountains. However, there is a distinct Sino-Tibetan group of species, possibly representing an undescribed subgenus. However, this idea is provisional and awaits revision of the genus. For present purposes, we assign these species to the subgenus Dichagyris. They share the following putative synapomorphies: black, dark brown or dark greyish forewing ground colour (with one exception), with obscure, reduced wing pattern and a broad-based, short, conical harpe in the male genitalia. Species of this group can be subdivided to two species-groups. In the astigmata-group which was mentioned for the first time by Hreblay et al. (1998) but without description or diagnosis from the minuta-group, the vesica is elongate and tubular (males), the appendix bursae and corpus bursae are long, sack–like, almost equal in size (females). In the minuta-group, the vesica is more ample than in the astigmata-group, and coiled, and the appendix bursae is globular and much shorter than the corpus bursae. The astigmata-group includes Dichagyris astigmata (Hampson, 1906), D. gansuensis Hreblay & Ronkay, 1998, D. geochroides (Boursin, 1948) and D. vargazoli (Gyulai & Ronkay, 2001). The minuta-group comprises D. minuta Hreblay & Plante, 1998 and D. kormos Gyulai & Ronkay, 2001. During a research expedition in Sichuan in 2019, the existence of a third species in the minuta-group was recognized, which is described here. In addition, the female and its genitalia of D. gansuensis, which was described by Hreblay & Ronkay (1998) based on a single male, are illustrated here for the first time.

A new species of Canthon is described, illustrated and the morphological similarities with related species are discussed. The species Canthon cleidecostae was named after Dr. Cleide Costa a great beetles specialist. The subgeneric category of species is considered incertae sedis until the taxonomic revision of the genus Canthon is fully addressed. Also, we provide a key for genera, subgenera and isolated species-groups that can be confused with the genus Canthon.

A New Species

The genus Elaphropeza Macquart from the Oriental region is revised. In addition to the 79 known species (including seven new combinations of species previously placed within Drapetis Meigen) 51 new species are described and illustrated. The study is mainly based on freshly collected material in Singapore (544 samples, year cycle in eight stations and numerous hand captures). Smaller samples were available from Malaysia, Thailand and Cambodia. Of the 51 new species only 43 have been given a name: E. acantha sp. nov., E. asexa sp. nov., E. asiophila sp. nov., E. belumut sp. nov., E. benitotani sp. nov., E. bezzii sp. nov., E. bulohensis sp. nov., E. chekjawa sp. nov., E. combinata sp. nov., E. crassicercus sp. nov., E. darrenyeoi sp. nov., E. demeijerei sp. nov., E. equalis sp. nov., E. feminata sp. nov., E. flavicaput sp. nov., E. furca sp. nov., E. limosa sp. nov., E. luanae sp. nov., E. luteoides sp. nov., E. malayensis sp. nov., E. meieri sp. nov., E. melanderi sp. nov., E. modesta sp. nov., E. monacantha sp. nov., E. monospina sp. nov., E. murphyi sp. nov., E. neesoonensis sp. nov., E. ngi sp. nov., E. pauper sp. nov., E. pluriacantha sp. nov., E. riatanae sp. nov., E. sime sp. nov.,E. singaporensis sp. nov., E. singulata sp. nov., E. sivasothii sp. nov., E. spicata sp. nov., E. spiralis sp. nov., E. sylvicola sp. nov., E. temasek sp. nov., E. tiomanensis sp. nov., E. ubinensis sp. nov., E. yangi sp. nov., E. yeoi sp. nov. Eight species known only as females are briefly diagnosed but not named. Species (including type materials in most cases) described by C.R. Osten-Sacken, M. Bezzi, J.C.H. de Meijere, R. Senior-White, A.L. Melander and K.G.V. Smith were examined and re-described. Neotypes have been designated for E. calcarifera Bezzi, E. melanura Bezzi, E. formosae Bezzi and E. scutellaris Bezzi. Elaphropeza exul Osten-Sacken, 1882 is transferred as Crossopalpus exul (Osten-Sacken) comb. nov. Elaphropeza formosae Bezzi sensu Quate, 1960 re-described by L.W. Quate from Micronesia, is considered a new species and a new name is given: E. quatei sp. nov. All species of Elaphropeza are divided into two main species groups: E. biuncinata group and E. ephippiata group. Phylogenetic relationships within Elaphropeza are provisionally outlined. Some interesting morphological features and phenology of the species are discussed. Fourteen species have been found exclusively in mangroves. A key is given to the species of the Oriental Region (Indian subcontinent, Southeast Asia, Philippines and Taiwan, but excluding certain species of the Chinese mainland that proved to be different from the rest of the Oriental Region). A check list of the Oriental species is provided.
