Abstract. The Tachyusa coarctata species group is revised. The species group is defined on the basis of the distinctly asperate punctation on elytra, the dense punctation on tergites III-V with interstices between punctures 1.5-2.0 times their diameter, and the dense, subrecumbent pubescence on the abdomen. The T. coarctata species group is composed of twenty three species restricted in occurrence to the Holarctic and Africa, including one new species described from Iran: Tachyusa frischi sp.n. A revised key to the species in this group is provided. An analysis of the phylogeny of the Tachyusa coarctata species group based on cladistic methods is presented and the phylogenetic relationships among species are discussed. . T. americanaCasey -Antennomeres 2 and 3 subequal in length; elytra long with length at suture equal to pronotal length at midline; aedegal median lobe approximately straight apically (Fig. 55) Description Body. Length 2.7-3.0 mm, convex, parallel-sided, glossy (Fig. 1); ground colour black; legs brown with reddish tarsi, antennae brown.Head circular in outline, moderately convex, eyes large, moderately protruding from lateral contours of head, length of each seen from above subequal to that of postocular region; surface of head without microsculpture; punctation fine and dense. Antennae relatively long, 623Figs 6-7. Abdomens of two species of Tachyusa Erichson: 6 -T. objecta; 7 -T. americana. Scale bar: 0.5 mm.extending to base of pronotum, weakly increasing in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4-10 longer than wide, antennomere 11 nearly conical.Pronotum quadrate, sides straight and gradually converging toward obtuse hind angles; before base with small and shallow transverse impression; surface without microsculpture; punctation fine, dense and asperate; pubescence at midline directed posteriorly.Elytra subquadrate, at suture as long as pronotal length at midline; surface lacking microsculpture; punctation fine, dense and asperate.Abdomen (Fig. 2) parallel-sided, bases of tergites III-V each with deep transverse impression, impressions with 7-8 longitudinal ridges, tergal punctation fine and moderately dense, punctures moderately small and well visible, surface without microsculpture. Figs 3-4. Female. Spermatheca as in Fig. 5 Remarks. Externally, Tachyusa frischi sp. n. is similar to T. coarctata Erichson, 1837, but can be distinguished from that species as the antennomeres 2 and 3 are subequal in length (antennomere 3 shorter than 2 in T. coarctata) and by the shape of aedeagus: median lobe of aedeagus in lateral view very short, subequal in length to apical margin of distal crest (Fig. 3). In the shape of genitalia, the new species is closely related to T. concinna Heer, 1839, but may be separated from that species as the head and pronotum lacks microsculpture, the abdominal basal transverse impressions lack a median carina and the apex of median lobe of the aedeagus in lateral view is triangular (rounded in T. concinna, Fig. 16). Male. Aedeagus as in PH...
