Microhoria olivacea species-group

Diagnosis. Mostly smaller species, with unicolorous elytra ( Fig. 140 ); moderately variable in pronotal characters, mostly with weak latero-basal impressions and uniformly short setation; elytral setae at most weakly divergent in postbasal area. Mesoventrite with nearly completely bordered lateral margins (Figs 21, 22), submarginal sulcus thin and sometimes inconspicuous laterally; setose fringe of mesepimera well-developed (Fig. 22); submarginal setose impressions of metaventrite and abdominal sternum III absent; all tibiae with paired terminal spurs; elytral apices in males nearly simple, pores scattered along somewhat swollen margin, similar to Fig. 46 . Aedeagus ( Figs 78–81 ): tegmen rounded to more or less distinctly bilobed apically (‘capsuliform’), ventrally denticulate on outer side; gonopore free.

Distribution. Western Mediterranean Region ( Algeria, Italy, Portugal, Spain, Tunisia).

Species included (8 spp.). Microhoria bruckii (Kiesenwetter, 1870) comb. nov., M. olivacea (LaFerté-Sénectère, 1849) comb. nov., M. platiai (Degiovanni, 2000) comb. nov., M. semidepressa ( Pic, 1893) comb. nov., M. subaerea (Reitter, 1890) comb. nov., M. subsericea ( Pic, 1898) comb. nov., M. velox (LaFerté-Sénectère, 1849) comb. nov., and M. viturati ( Pic, 1893) comb. nov.

Remarks. This species-group holds some species placed previously in Tenuicomus and Clavicomus ( CHANDLER et al. 2008, as Tenuicollis and Clavicollis). They share nearly all characters of the M. heydeni species-group, but differ by the simple tegmen that is at most shortly bilobed at the apex.
