Kirejtshuk, A. G.: New taxa of Nitidulidae (Coleoptera) from the Indo-Malayan fauna

cavities following closely their posterior edge. Apex of last abdominal sternite widely rounded off. Elytral epipleura feebly upwardly sloping laterally. — Tibiae subequal and thin, 2/5 as wide as antennái club, whit aised projection at their apical outer corner. Femora 2.5 times wider than tibiae. Tarsi nearly 1/4 as wide as tibiae, their claws fairly thin. — Genitalia: Ovipositor slightly sclerotised. Diagnosis. — P. martini sp. n. is especially outwardly similar to P. nobilis REITTER, 1873 (= P. yunnanensis GROUVELLE, 1910, syn. n.*) but differs from it in its weakly pubescent and more shiny body, type of puncturation, antennái club shape as well as in its distinct ovipositor. Pocadius decoratus sp. n. (Figs. 101-106) Material: 1 çf, holotype : N. Vietnam, Thainguyen, 50 km NO., 9 Jan. 1964, O. KABAKOV. (ZIN). Male. Length 4.1, breadth 2.2, height 1.3 mm. Oviform, moderately convex; reddish with black pattern on dorsum (see Fig. 101); shiny; with sparse, moderately long, feebly conspicuous yellowish pubescence, pronotal and elytral sides sparsely and finely ciliate. — Head not deeply concave behind antenna! insertions, its anterior margin straight with corners narrowly rounded off. Surface with shallow oval punctures, 2-3 times as large as eye facets, separated by distance equal to 1/3-2/3 puncture diameter, intervals smooth and shiny. Antennae 3/4 as long as head wide, their club composing 2/5 antennái total length. Pronotum distinctly bordered as laterally as along anterior and posterior margins, its sides subexplanate in anterior 1/2. Surface as on head, but punctures sparser. — Scutellum semicircular, with very sparse smallest puctures. — Elytra with well raised shoulders, subsutural lines visible in distal 1/2 and their sides narrowly subexplanate and bordered. Surface with 9 longitudinal rows of punctures somewhat larger than largest ones on head and pronotum and very small, irregular punctures between rows, space between them smooth and shiny. — Pygidium with apex transversely abrupt, its surface about same as on head but with space between punctures close-meshly reticulated. — Ventral surface almost inconspicuously pubescent and considerably more sparsely punctured. Prosternai process slightly convex before apex. Distance between all corresponding coxae subequal. Metasternum weakly depressed in distal 1/3 before hind edge, between hind coxae shallowly emarginate. Apex of last abdominal sternite almost bisinuate. — Tibiae narrow, fore hardly more, intermediate subequal and hind distinctly less than 1/2 antenna! club. Tarsi about 1/3 as wide as fore tibia, their claws simple. — Genitalia: Aedeagus moderately sclerotised. Diagnosis. — P. decoratus sp. n. is clearly distinct from all the species formerly described as members of Pocadius. This species together with P. nobilis and P. martini sp. n. from a group of closely related species (nobilis-group). Except coloration P. decoratus sp. n. differs from both species in its larger body with oviform shape, antennái club and tibiae with fairly prominent subapical projection. Pocadius kabakovi sp. n. (Figs. 107-113) Material. 5 çf, 9, holotype rf (ZIN) and paratypes çf, 9, (ZIN) and (TM): N. Vietnam. 40 km NO of Thainguyen, Sammak, 13-15 Jan. 1964, O. KABAKOV; 2 paratypes: ibid., 50 km NO of Thainguyen, 12 Jan. 1964, O. KABAKOV (ZIN); 5 specimens, paratypes: ibid., Binhtrithien, 40 km NW of Donghoi, 23-27 March 1963, O. KABAKOV (ZIN). Male, holotype. Length 3.4, breadth 2.1, height 1.3 mm. Oval, robust, rather convex; elytra black with reddish pattern at basis, pronotum, head, scutellum and subsutural strips on elytra dark reddish brown; pygidium, ventral surface, legs and antennae reddish; almost dull; with dark (nearly black), moderately long and sparse, semi-erect hairs with blunt apices, but these dispersed together with pale ones on head, pronotum and elytral apices ; elytral reddish spots covered only by yellowish ones; pronotal and elytral sides without distinct ciliation. — Dorsal surface very similar * This synonymy is based on a study of many specimens of P. nobilis and the type series of P. yunnanensis from (RNH) with labels "Yunnan mission", "Pocadius yunnanensis cotype Grouv," the lectotype is designated here.
