description: Dermestocyphon (Oreocyphon) brancuccii sp. nov.
(Figs 7, 74–78)
Type material. HOLOTYPE: ♂ (CKD, to be deposited in Deutsches Entomologisches Institut, Müncheberg), “ Vietnam, N; 55 km NNW Hanoi, Tam Dao vill. env., 800–900 m NN, 11.– 14.08.1998, leg. A. Napolov ”.
Diagnosis. This species is similar to D. umbratilis known from Nepal and D. niisatoi sp. nov. It can be distinguished on the basis of the morphology of the aedeagus, which has a shallowly concave basal margin and a conically pointed trigonium.
Description. Male. Body oval, slightly convex dorsally, strongly shining, closely covered with easily removable setae throughout. Coloration of body completely black; mouthparts, antennae, middle and hind tibiae and tarsi yellowish-orange, all femora somewhat darker.
Head moderate in size, finely punctate, slightly convex dorsally; distance between eyes about 2.0 times as long as maximum diameter of eye. Eyes moderate in size, slightly prominent. Pronotum transverse, strongly depressed in lateral parts, finely punctate; anterior margin almost straight; anterolateral angles obtuse, slightly projecting anteriorly; lateral and posterior margins almost straight; posterolateral angles about 90°; PW/PL 2.27. Scutellum small, equilateral-triangular, finely punctate. Elytra oval, widest at middle, closely punctate, gently arcuate at lateral margins; shoulder parts slightly elevated; EL/EW 1.29; EL/PL 4.44; EW/PW 1.51; TL/EW 1.58. Legs relatively short.
Caudal margin of sternite VII arcuate, somewhat pointed in middle (L 0.89 mm, W 0.30 mm). Sternite IX (L 0.14 mm, W 0.25 mm) moderately sclerotized, semicircular, bearing long setae and short spines in apical portion; tergite VIII moderately sclerotized, transversely trapezoidal (plate W 0.37 mm, L 0.18 mm), bearing short spines at mesal portion of posterior margin, this part is more curved, bearing short setae in posterolateral portions, with a pair of short apodemes (L 0.25 mm); tergite IX slightly sclerotized, with a pair of long apodemes. Tegmen short, slightly sclerotized; parameres short, with broad rounded apices (L 0.16 mm; W 0.20 mm); lateral projections long (L 0.46 mm), pointed at apices. Penis moderately sclerotized (L 0.53 mm, W 0.14 mm), widest at basal 1/4; pala oval, shallowly concave at basal margin; parameroids long, slender, closely punctate; trigonium short, triangular, apex carved, covered with very short microtrichia, partly arranged in rows.
Female unknown.
Measurements. Male (n = 1): TL 2.61 mm; PW 1.09 mm; PL 0.48 mm; EW 1.65 mm; EL 2.13 mm.
Etymology. This species is named after the late Coleoptera curator in Naturhistorisches Museum Basel, Dr. Michel Brancucci (1950–2012), an expert on water beetles, who had great merits for the study of Coleoptera from Southeast Asia.
Distribution. Vietnam.
