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

edge weakly emarginate and corners rounded off. Surface with irregular shallow punctures thrice as large as eye facets, separated by distance equal to 1/3-1/2 puncture diameter. Intervals alutaceous. Antennae almost 4/5 as long as head wide, their club composing 2/5 total antennái length. — Pronotum with hind corners rounded off, its sides narrowly subexplanate, distinctly bordered as laterally as along posterior and anterior margins. Surface about same as on head with punctures sparser and with very small punctures (smaller than eye facets) between larger ones. — Scutellum subsemicircular, its surface aproximately as on head. — Elytra with well raised shoulders, subsutural lines visible in distal 1/2 and sides not subexplanate, rather narrowly bordered. Surface with 9 longitudinal rows on each elytron of large punctures, somewhat larger than those on head and elytra, between rows with centrally placed irregular lines of fairly small punctures. — Pygidium with apex transversely abrupt and rounded off at sides, much more densely and finely punctured than head and pronotum. -— Ventral surface as pubescent as dorsal, puncturation about same as on pygidium but on middle of metasternum with punctures considerably smaller and sparser. Prosternai process rhomboid, with apex rounded off. Distances between intermediate and hind coxae 1.2 times as large as that between fore ones. Metasternum widely and shallowly depressed in middle with shallow angular hind margin between hind coxae. Apex of last abdominal sternite rounded off. Elytral epipleura upwardly sloping laterally. — Fore tibia narrow with strong projection on its outer edge before apex, intermediate and hind ones somewhat narrower and apical projection much less expressed and displaced to apex. Tarsi about 1/4 as wide as fore tibia, their claws thin. — Genitalia : Aedeagus strongly sclerotised. Female. Externally differs from male only in pygidial apex being widely rounded off, without visible anal sclerite. — Genitalia: Ovipositor well sclerotised. Variation. Length 5.5-7.0 breadth 3.0-3.3 mm. Antennái club and ventral surface of some paratypes are in part darkened. Certain variability is found in the puncturation of the surface. Diagnosis. — P. majusculus sp. n. is the largest among the known species of Pocadius. It is most similar to P. tastaceus GROUVELLE, 1892; known to author only from a specimen, male with label "Ind. or. BIRO, 1902, Matheran, 800 mm" (TM), but distinct from it in having larger and denser punctures, in the shapes of the prosternai process and scapus (Figs. 91-92) as well as aedeagus structures (Figs. 93, 94). Pocadius martini sp. n. (Figs. 95-100) Material. 1$, holotype: "Philippines, Palawan, Mantalingajan, Pinigisan, 600 m, caught in Malaise trap, 4 Sept. 1961, Noona Dan exp." (ZM). Female. Length 3.3, breadth 1.8, height 0.9 mm. Elongate oval, moderately convex; brown (nearly chesnut), tibiae and tarsi somewhat lighter, with yellowish spot at suturai corner on elytra; shiny; with pronouncedly sparse, somewhat shortened yellowish grey pubescence forming on each elytron longitudinal rows (about 18), pronotal and especially elytral sides and pronotal basis distinctly ciliate, hairs along elytral margin as long as on disc of pronotum and elytra. — Head shorter than distance between eyes, comparatively deeply concave behind antenna! insertions, its anterior margin with indistinct clypeus. Surface with oval, somewhat shallow punctures, 1.0-1.5 times as large as eye facets, separated by distance equal to 0.5-1.0 puncture diameter, space between them densely and finely alutaceous, almost smooth and shiny. Antennae sligthly longer than distance between eyes. — Pronotum with gently convex sides not widely subexplanate and basal border distinct. Surface nearly as on head, but intervals much more than a puncture diameter. — Scutellum subtriangular with apex widely rounded off, its surface only with some very small punctures and traces of reticulation at pronotal edges. — Elytra with shoulders moderately raised and sides narrowly bordered, their subsutural lines visible in distal 1/2. Surface with 9 longitudinal rows of shallow punctures on each elytron, about 2.5 times as large as eye facets, separated in the rows by distance equal to 1/2 diameter of large puncture, between the rows nearly 1.5 times of a diameter puncture, between rows of large punctures rows sparse with very small punctures, intervals smooth and shiny. — Pygidium with apex rounded off, its surface with dense punctures, 1.5 times as large as eye facets, intervals with traces of crossundulate reticulation. — Ventral surface inconspicuously pubescent puncturation on prosternum nearly as on head, but one on metasternum about same as on scutellum. Abdominal sterna with strongly shallow punctures, intervals as well as those of sterna of thorax smooth or finely alutaceous. Prosternai process flattened, with apex pointed. Metasternum rather convex with hind margin between hind coxae shallowly emarginate. Distance between intermediate coxae subequal to that between fore and hind ones. Caudal marginal lines of hind coxal
