- P. intermedia sp. n.; - P.japonica REITTER, 1873 (Pocadius) (= Pocadius unicolor REITTER, 1884; Pocadius rufimargo REITTER, 1884); - P. latipes (REITTER, 1884) (Lordyrodes); - P. olexai JELÍNEK, 1999; - P. pallentis (KlREJTSHUK, 1984) (Atarphia); - P. pseudoexplanata JELÍNEK, 1999 ; - P. reitteri GROUVELLE, 1892; - P. schneiden JELÍNEK, 1999; - P. taiwanensis sp. n.; - P. uhligi (KlREJTSHUK, 1984) (Atarphia); - P. wajdelota (WANKOWICZ, 1869) (Pocadius). Kryzhanovskiella gen. n. Type species - Atarphia pecki KlREJTSHUK, 1986, herewith designated. Other species included - Atarphia aequilibris KlREJTSHUK, 1986. Description - The species included in the new genus were described in detail by KlREJTSHUK (1986) and, therefore, it seems sufficient to mention only the main features of these two species that justify proposing a new taxon for them. They are: 1) pronotum evenly convex, with subexplanate sides strongly narrowed from base; 2) elytra with widely explanate sides and more or less expressed longitudinal (double) rows of punctures on even surface; 3) dorsal pubescence conspicuous and consisting of two kinds of hairs (subrecumbent and moderately long ones; erect, very long ones, which are with stout and blunt apices, sometimes forming separated brushes of hairs and arranged in more or less expressed longitudinal rows on elytra), or hairs of the second kind partly reduced; 4) pronotal and elytral sides moderately shortly ciliate; 5) tibiae narrow and simple, protibia with rounded subapical angle, but meso- and metatibiae with a pair of subapical spines at outer subapical angle; 6) tarsomeres 1-3 weakly lobed with brushes of hairs; 7) antennái grooves distinctly convergent; 8) prosternal process extended as a pleat covering the middle of mesosternum; 9) posterior edge of metasternum slightly emarginate; 10) distance between mesocoxae subequal to, and that between metacoxae about twice more than that between procoxae; 11) submesocoxal lines deviating from posterior edge of mesocoxa only at outer angle of metasternum; 13) submetacoxal lines gently deviating before the middle of posterior edge of cavity and returning at outer part of cavity; 14) epipleura rather wide and nearly horizontal; 15) male pygidium subtruncate and anal sclerite exposed from beneath it; 16) ovipositor with fused and strongly modified sclerites of coxites, which are with a simple joined apex, lateral projections and raised styli or without the latter. Comments to generic composition - The Pocadius complex of genera is recognized here as a provisional unit, because different members of it have much parallelism in structures and bionomy with the complexes of the genera Ipidia, Soronia, Phenolia and Thalycra, especially with the latter two. Some genera included in the Pocadius complex were considered with other possible relationship and another composition of the complexes (JELÍNEK 1982, 1999, AUDISIO & JELÍNEK 1993). Phylogenetic relationships between members of this complex as well as those between different com-
