description: Hajekia gen. nov.   
 Type species. Hajekia microps sp. nov., by present designation.   
 Description. Body small, elongate, very strongly punctured. Vestiture of head, pronotum and elytral disc consists of minute very sparse recumbent, almost invisible setae, which are semierect and a little longer on elytral declivity. Head globose. Eyes very small, strongly protruding, temples strongly narrowing towards eyes. Rostrum thick, curved, elongate, slightly dilated at apex, and almost continuing outline of head. Antennae elongate and inserted near apex of rostrum, scape sinuous and quite strongly widening beyond middle, funicle of five antennomeres, antennomere I much longer than others which are all not transverse, club fusiform. Pronotum rather elongate, strongly constricted towards apex, apical margin moderately convex, base truncate. Scutellum minute. Elytra elongate and subparallel sided, shoulders absent. Striae formed by deep punctures, intervals keeled, and granulate at least on posterior third. Femora clubbed, edentate, slightly curved and quite compressed. Tibiae rather short and moderately thick, apical uncus fairly strong. Tarsi robust, tarsomere III bilobed, claws free. Procoxae more approached posteriorly than to anterior margin of prosternum, mesocoxae separated by interval at most equal to their diameter, metacoxae separated by distance from slightly less to slightly more than their diameter. Metaventrite truncate anteriad. Abdominal ventrites I and III elongate, suture between them barely visible, ventrites III and IV very short, their combined length about half of that of ventrite II, ventrite V rather elongate and crescent-shaped.   
 Differential diagnosis. This genus shares with the widespread Dryotribus Horn, 1873 size, general aspect, pentamerous funicle, small eyes, and suture between ventrites I and II obsolete (HORN 1873). Hajekia gen. nov. clearly differs from Dryotribus by antennae inserted in the apical third or apicad of it instead about in the middle of rostrum, eyes much smaller and protruding, and temples very strongly instead of moderately narrowing towards apex (Figs 16, 18, 20). The appearance of the new genus is also very similar to Dryotribodes Zimmerman, 1942 from the Pacific islands, but the latter has a heptamerous funicle (ZIMMERMAN 1942) and it is thus immediately distinguished from Hajekia gen. nov. There are no other Dryotribini which can be confused with this new genus, except the Socotran Bezdekiellus gen. nov. described below which clearly differs from Hajekia gen. nov. by its eyes reduced to a single ommatidium.   
 Etymology. The genus is named after Jiří Hájek who collected the two specimens of its type species. Gender is feminine.
