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)

rounded apices forming a clear suturai angle. This new genus differs from Hyleopocadius in the smaller body, maximum width of pronotum at its base, not very widely explanate pronotal and elytral sides, which are without long cilia, scarcely seriate elytral punctuation, lack of distinct ridge at anterior edge of metasternum and larger eyes. The species of the new genus differ from the Omositoidea gigantea SCHAUFUSS, 1892 in the smaller body size, more less distinct apices of posterior pronotal angles, much shorter cilia along pronotal and elytral sides, less distinct dorsal puncturation, more widely separated coxae in all pairs, narrower tarsi, and lack of sexual dimorphism in mesotibia. They are very distinct from Pocadius and Pocadites species in the evenly sloping pronotal and elytral sides, complete elytral apices, lack of distinct longitudinal rows of punctures, much wider and subhorizontal epipleura, not elevated middle of the prosternum and almost simple tibiae (without prominent subapical process as in Pocadius or dilated as Pocadites), and from Pocadius also in the more widely separated metacoxae, and from Pocadites in the emarginated posterior edge of the metasternum between the coxae as well as less widely separated meso- and metacoxae. The genus Pseudoplatychora is a somewhat problematic member of the Pocadius complex. GROUVELLE was inclined to regard it as a synonym of Atarphia (GROUVELLE, 1913). However, JELÍNEK confirmed that Pseudoplatychora convexiuscula GROUVELLE, 1890 is distinct from Atarphia, and more similar to species of the genera Axyra ERICHSON, 1843, Megauchenia MACLEAY, 1825 and Platychora ERICHSON, 1843 than to any other groups; he regards its similarity to Atarphia as not "synapomorphic". Nevertheless, in addition to the different genitalia in both sexes and the shape of the pygidium, the species of Kryzhanovskiella gen. n. differ from Pseudoplatychora convexiuscula in the smaller and much shorter body size with less narrow pronotum, simple mentum, configuration of both submeso- and submetacoxal lines. The antennái grooves of Pocadius are arcuately convergent rather than subparallel, but never as curved as in Kryzhanovskiella gen. n. The tarsi of the new genus are rather narrow, although they are distinctly lobate as in many genera of the complex (but in contrast to simple those in Pocadius) or rather wider than those in Pocadites). The ciliation along the pronotal and elytral sides is strongly raised in Omositoidea, but usually very slightly developed (Hebasculinus, Hebascus, Hyleopocadius, Niliodes, some Physoronia and Pocadius) or (almost) invisible (in most cases).
