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

Tricanus ruficolor sp. n. (Figs. 114-122) Material. 1 çf, holotype: N.E. Burma, Kambaiti, 7000 ft., 26 April 1934. R. MALAISE (NR). Length 5.4. breadth 3.2, height 1.2 mm. Oval, rather convex ; reddish, almost brownish, shiny ; dorsum inpubescent, venter with hardly visible, thin and short pubescence on abdomen. — Head as long as distance between eyes, feebly concave between antenna! insertions. Antennae 3/4 as long as head wide. Pronotum gently convex at sides, not bordered at basis, with hind corners blunty pointed. Scutellum with apex rounded off. Elytra with weakly raised shoulders, its sides not explanate. Pygidi­um with abrupt apex and corners rounded off. — Surface of head, pronotum and scutellum with oval punctures somewhat more than eye facets, separated by a distance equal to about a puncture diameter, the intervals finely alutaceous. Surface of elytra with 9 longitudinal rows of dense punctures twice as large as eye facets, interstices with irregular and small punctures, space between them smooth and shiny. — Ventral surface extremely finely and sparsely punctured and alutaceous or shiny. Distance between intermediate and hind coxae approximately 1.7 times more than that between fore ones. Metasternum flattened with hind margin between hind coxae moderately emarginate. Apex of last abdominal sternite rounded. — Femora 3 times as wide as tibia. — Genitalia: Aedeagus moderately sclerotised. Diagnosis. — 77. ruficolor sp. n. is clearly distinct from all its known congeners in its much more slender and unicolorous body as well as its particularities of prosternai pro­cess, tibiae and genital structures. Cychramus malaisei sp. n. (Figs. 123-127) Material. I çf, holotype (NR) et 20 specimens, paratypes (NR and ZIN): N.E. Burma, Kambaiti, 2000 m, 1 May — 9 June 1934. R. MALAISE. This species is fairly similar to C. variegatus (HERBST) and partly to the following species. A complete description of this species is not necessary and therefore many features which are in common with these in other mentioned Cychramus species are omitted in the forthcoming section. Male, holotype. Length 5.7, breadth 3.3, height 1.7 mm. Oval dorsum evently convex, venter flat; dark pitchy brown; prothorax, except 4 almost black points on pronotum, mouthparts, antenna! flagelli, basis and subsutural strips on elytra as well as fore and intermediate legs, hind tibiae and tarsi considerably lighter (brown), but most part of elytra and antennái club almost black; moderately shiny ; very densely pubescent with long hairs on dark pronotal points and dark part of elytra blackish, but yellowish on rest of dorsum ; pronotal sides moderately and elytral ones strongly ciliate. — Head, pronotal and pygidial surface with oval punctures ever so less than eye facets separated by a distance somewhat more than a puncture diameter, interstices finely mesh-reticulated. Elytral one with feebly visible and sparser punctures hardly rugose, but interstices smoothedly reticulated. Ventral surface nearly as punctured as dorsal one, but with punctures larger and interstices with more distinct reticulation. Posterior pygidial edge slightly arcuate and apex of last abdominal sternite widely roun­ded off. — Genitalia: Aedeagus heavily sclerotized. Female. Head with 2 large and deep fossae at inner margin of eyes just the same as in female of C. variegatus (HERBST), with extremely long hairs around fossal edge. — Genitalia: Ovi­positor well sclerotized. Variation. Length 4.1-5.7, breadth 2.6-3.3 mm. Pronotal dark points occasionally not well expressed. Reticulation on dorsum of some paratypes fairly weakened. Density of puncturation somewhat variable. Diagnosis. — This species as well as the next one are distinguished from other species of Cychramus of the Palearctic and Indo-Malayan regions by using the key adopted here. Thanks to a number of specimens studied by the author, it may postulate that the name "dorsalis" is better regarded as an obvious junior synonyms of "luteus". The species­taxon "beccariV must be refered to Aethina species and not Cychramus (KIREJTSHUK in litt).
