Mahunka’ ( HNHM ) . Diagnosis. According to the head/pronotum width ratio of 0.65, this species resembles the Mimogonia antennata group having small eyes, and the species M. antennata Irmler, 1981 , M. subopaca Irmler, 1981 , M brunnea Irmler, 1981 , M. similis Irmler, 1981 , M. tricolor Irmler, 1981 , M. pumilia Irmler, 1981 , M. hermani Irmler, 2007a and M. huggerti Irmler, 2007a . Mimogonia baloghi sp. nov. can be identified only by its unique aedeagus. In particular, the compact coiling of the endophallus are characteristic for this new species. Description. Length: 2.3 mm . Colouration black; anterior half of head, pronotum and elytra light brown to yellow, with posterior margin of elytra darkish; legs and antennae yellow. Head 0.29 mm long, 0.42 mm wide; eyes only slightly prominent; setiferous punctation deep and coriaceous close to neck; punctation apically sparser with impunctate area on disc; setae yellow; net-like microsculpture weak; surface slightly shiny. Antennae as long as head and two thirds of pronotum combined; second antennomere oval and as long as conical third antennomere; fourth antennomere small, not wider than third; the following antennomeres increasing in width; tenth antennomere nearly twice as wide as long. Pronotum 0.38 mm long, 0.64 mm wide; sides in apical two thirds more or less parallel, in posterior third deeply emarginate; setiferous punctation as deep and dense as on head; distance between punctures as wide as or slightly closer as diameter of punctures; setae yellow, pointing to the centre of posterior edge; net-like microsculpture weak; surface slightly shiny. Elytra 0.49 mm long, 0.50 mm wide; setiferous punctation as deep and dense as on pronotum; interstices between punctures on average as wide as diameter of punctures; pubescence yellow, pointing to the centre of posterior edge; along suture pointing more or less parallel to suture; net-like microsculpture much deeper than on head and pronotum; thus, surface matte. Abdomen with deep net-like microsculpture; surface matte; setiferous punctation weaker than on fore-body, but as dense; pubescence yellow, pointing posteriad. Mesotibia of male without emargination on inner side, but with row of spines at outer apical edge. Aedaegus with hook-like apex; endophallus with spiral structure at base and more laminar structure at apex. Etymology. This species is named after its collector Janos Balogh. Distribution. Known only from the type locality.
