E-mail: cydnus@uni.opole.pl Abstract Ochetostethomorpha secunda sp. nov. from Namibia, the second species of the South African endemic genus is described, illustrated, and compared with O. nollothensis Schumacher, 1913. The new species is the third of the subfamily Sehirinae known from Namibia. Moreover, a DNA barcode sequence was generated for this new species (827 bp of cytochrome oxidase I) and was deposited in GenBank. Key words: Sehirinae, Ochetostethomorpha, taxonomy, endemic genus, Mopane savanna, Namibia, DNA barcode Introduction Thirteen species of the family Cydnidae (sensu Pluot-Sigwalt and Lis 2008) have been recorded from Namibia (Hesse 1925; Linnavuori 1993; Lis 1999, 2000, 2011; Robertson 2009; Lis and Ziaja 2014), including a single species of the subfamily Amaurocorinae, i.e., Angra ciliata Schumacher; two species of the subfamily Cephalocteinae, i.e., Cephalocteus punctipennis Stål and Heissocteus ernstii J.A. Lis; nine species of the subfamily Cydninae, i.e., Aethus hirsutus (Hesse), A. perosus Stål, Fromundus difficilis (Stål), Geocnethus plagiatus (Signoret), Lactistes falcipes Hesse, Macroscytus brunneus (Fabricius), M. reflexus Signoret, Microporus lautipennis (Stål), M. pallidipennis (Reuter); and a single Sehirinae species, i.e., Legnotus melaleucus (Thunberg). The genus Ochetostethomorpha was described for a single species new to the science, i.e., O. nollothensis from Port Nolloth, Namaqualand in the Republic of South Africa (Schumacher 1913). A redescription of this genus and species (based on the six originally collected specimens), as well as the lectotype designation was provided by Linnavuori (1993). Subsequently, this species were reported also from Chad (Lis 1996) based on three females collected during the French Chari-Lac Tchad 1902–1904 expedition. No other specimens of this genus have been reported since that time. In its crucial generic characters, i.e., evaporatoria (Linnavuori 1993), metathoracic wing venation (Lis and Heyna 2001), cephalic chaetotaxy (Lis and Pluot-Sigwalt 20002), trichobothrial pattern (Lis and Hohol- Kilinkiewicz 2002), as well as tibial and coxal combs (Lis and Schaefer 2005; Lis 2010), the genus Ochetostethomorpha is very similar to species of the genus Ochetostethus Fieber, 1860. However, both genera are easily separable by the shape of the prosternal carinae (Ochetostethomorpha—prosternal carinae high, ending posteriorly in a horn-like process, Fig. 1a; Ochetostethus—prosternal carinae narrow, posteriorly rounded, Fig. 1b). During field studies carried out by the fourth author (RD) in Ovamboland (Namibia), two male specimens of the genus Ochetostethomorpha were collected; they appeared to represent a new species of this endemic genus.
