Kirejtshuk, A. G.: New species of the genus Physoronia from the Far East and Kryzhanovskiella gen. n. from Australia, with taxonomic notes on the Pocadius complex (Coleoptera: Nitidulidae)

P. explanata also in the deeper median excision between coxites of the ovipositor, and from P. pseudoexplanata also in the shape of the male anal sclerite. Besides, this new species is distinct from Physoronia schneiden JELÍNEK, 1999, another member of the genus known from Taiwan, which has also rounded apex of the pe­nis trunk, in the more or less expressed infuscations on dorsal sclerites, more con­spicuous long hairs curved and narrowed apically, strongly closed labral lobes, in the different shape of antennái club, pronotum more narrowed at base, shallower and indistinct paramedial depressions behind mentum, more narrowly separated all pairs of coxae, widely rounded apex of prosternai process, median emargina­tion of apex of anal sclerite and peculiar armature of inner sac of penis. Physoronia intermedia sp. n. (Figs 7-16) Type material - "Ussuri, Maritime Terr., Hassan Distr., 23-24.V. 1990, Ryazanovka, S. Ka­zantzev" (holotype, female, Naturhistorisches Museum in Basel, and 1 paratype, female Zoological Institute of Russian Academy of Sciences, St. Petersburg). Description of female (holotype) - Length 5.0, width 3.0, height 1.8 mm. Rather convex dor­sally and slightly ventrally; most part of pronotum and elytra dark brown to black, head, explanate pronotal sides, prescutellar places of elytra and pygidium reddish; metasternum and ventrites chest­nut brown, remainder of underside and appendages reddish brownish (except dark antennái club); rather dull because of dirty surface, although integument smooth and shining; dorsum with very sparse and short subrecumbent hairs, much shorter than distance between their insertions, besides, with very long, subercct dark or sometimes light spines with stump apices, somewhat longer than dis­tance between their insertions and longer than tarsal claws; underside with thin and moderately con­spicuous hairs, about as long as distance between their insertions. Head and prosternum with very large shallow punctures, interspaces between them 1/4-1/3 of puncture diameter and alutaceous. Pronotum with shallow and almost indistinct punctures and smoothed interspaces between them. Elytra with moderately large, not quite distinct, shallow and partly depressed punctures, 2-3 times as large as eye facets in diameter, interspaces between them 2-3 puncture diameters and rather smooth (punctures forming indistinct longitudinal rows). Pygidium with almost distinct punctures, somewhat larger than eye facets in diameter, interspaces about equal to puncture diameter. Ventrites with shallow distinct punctures, about twice larger than eye facets in diameter, interspaces between them somewhat less than a puncture diameter (inter­spaces on ventrite 1 even markedly broader than a puncture diameter), finely alutaceous to finely microreticulated. Metasternum about as punctured as ventrite 1, but interspaces between punctures completely smooth. Head slightly depressed behind antennái insertions and at inner eye edges, about 5/6 as long from truncate anterior edge of frons to file on vertex as the distance between moderately large eyes (consisting of moderately small facets), with temples not extended beyond level of outer edge of eyes; parocular ridges clearly raised in the posterior half and joined with transverse occipital line. Labrum moderately exposed, subtruncate and medially sutured. Mandibles slightly exposed. An­tennae slightly shorter than head, wide, their club subovoid, about 1 and 1/3 as long as wide, compos-
