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 : 117-118

Microhoria fugax species-group

Diagnosis. Small to medium-sized species, with uniform setation of elytra; rather variable in shape of head and pronotum, the latter mostly distinctly constricted in dorsal view and with uniformly short setae ( Figs 128–130 ). Mesoventrite with nearly completely bordered margins (sulcus always rather distinct), and frequently with short submedian carinae, at least indicated posteriorly ( Figs 29, 30 ); setose fringe of mesepimera strongly reduced ( Figs 30 , 35 ); submarginal setose impressions of metaventrite and abdominal sternum III indistinct; metatibiae almost exclusively with single terminal spur (see Remarks); elytral apices in males nearly simple, secretory pores situated directly on/near margin ( Fig. 45 ), which is usually somewhat swollen, uneven, bearing small projection. Aedeagus ( Figs 54–61 ): tegmen with distinct, narrowed apex, mostly weakly sclerotized; endophallus always with longitudinal sclerite (gonopore situated apically, Figs 54 , 60 ), in addition to various spinules, sometimes also with spines arranged in longitudinal row on connecting membrane ( Fig. 55 ) and membranous inner sheath ( Fig. 56 ).

Distribution. Eastern Palaearctic and Oriental Region, most speciose in the Himalaya and mountains of SW China (Yunnan). The westernmost records originate from eastern Afghanistan.

Remarks. This group holds nearly all Eastern Palaearctic (from Afghanistan eastwards) and Oriental species placed previously in Clavicomus ( CHANDLER et al. 2008, as Clavicollis) with the exception of C. protervus (Krekich- -Strassoldo, 1931) from northern India (Uttarakhand).

The terminal spurs of the metatibiae were found to be further reduced in males of species that exhibit modifications of the terminal portion of the tibiae; they are both absent in M. anomala and M. kejvali (based on tentatively identified specimens, ZKDC), and in two unnamed species from China and Laos (ZKDC).
