Kejval, Zbyněk & Chandler, Donald S., 2020, Generic revision of the Microhoriini with new species and synonymies from the Palaearctic Region (Coleoptera: Anthicidae), Acta Entomologica Musei Nationalis Pragae 60 (1), pp. 95-154 : 119

Microhoria heydeni species-group

Diagnosis. Mostly smaller species, with unicolorous elytra, and elytral setae at most weakly swirled in postbasal area (no conspicuous setose bands); pronotum moderately constricted in dorsal view, with uniformly short setae ( Fig. 133 ). Mesoventrite with nearly completely bordered lateral margins, submarginal sulcus delicate (Figs 15, 16), sometimes inconspicuous laterally; setose fringe of mesepimera well-developed; submarginal setose impressions of metaventrite and abdominal sternum III absent; all tibiae with paired terminal spurs; elytral apices in males nearly simple, secretory pores scattered along somewhat swollen margin ( Fig. 46 ). Aedeagus ( Figs 62, 63 ): tegmen with rounded apex (‘capsuliform’), and with robust subapical projection(s); gonopore free.

Distribution. Western Mediterranean Region ( Portugal, Spain) and Canary Islands.

Species included (5 spp.). Microhoria barnevillei (Pic, 1892) comb. nov., M. heydeni ( Marseul, 1879) comb. nov., M. martinezi (Pic, 1932) comb. nov., M. schrammi (Pic, 1913) comb. nov., and M. uhagoni ( Pic, 1904) comb. nov.

Remarks. This species-group holds species previously placed in Clavicomus and Tenuicomus ( CHANDLER et al. 2008, as Clavicollis and Tenuicollis). They can be easily confused with members of the M. olivacea species-group, differing mainly by the peculiar shape of the tegmen, which has robust subapical projection(s). Two species, M. martinezi and M. uhagoni, are known to the authors only from their female types, and their tentative placement here is based on external similarity.
