description: Holcoferonia crassimargo Tschitschérine, 1898, comb.n.
Figs 37–38, 43, 76, 108–109, 114, 120–121.
Tschitschérine, 1898: 453–454 (Holconotus; Pnom-Penh, Cambodia). — ferrugineus: Bates, 1889: 277; Andrewes, 1921: 179 (part.).
MATERIAL. 2♂♂, 5♀♀ (SIEE): Southern Vietnam, Dong Nai Province, Cat Tien National Park, at light, 27.X–4.XII.2004 (D. Fedorenko).
DIAGNOSIS. Larger species, with pronotal lateral bead much thicker basally than apically, pronotum more distinctly punctate outside basal sulci, abdominal sternite VII only laterally punctate, and aedeagus distinctive.
REDESCRIPTION. BL 4.3–4.6 mm. Body (Fig. 76) shiny, dark reddish brown, elytra basally, apically and laterally paler, pronotum deep red; legs, antennae and mouthparts red; venter red to reddish brown. Elytra very slightly opalescent due to microsculpture consisting of nearly indistinct, dense, transverse lines.
Pronotum a third wider than long, PW/PL 1.32–1.39 (1.35, n=5), three fourths wider than head, PW/HW 1.72– 1.80 (1.75), broadest just medially, PLw/PL 0.50–0.56 (0.52), sides nearly parallel and subsinuate to straight in basal half, rounded before. Base truncate, half wider than apex, PB/PA 1.48–1.58 (1.52), basal angles hardly more than right, with a nearly indistinct minute tooth; apex almost truncate, apical angles barely projecting, right and blunt. Lateral bead fine at apical angles, thick behind anterolateral seta; lateral groove almost as wide as lateral bead, finely and densely punctate inside; basal bead vague outside basal sulci, apical fine, obliterate in middle fifth. Basal region halfway between lateral margin and basal sulcus with a group of a few more or less dense punctures reminiscent of a vestigial outer basal sulcus half as long as basal sulcus proper (in one paratype, only two fine punctures are present).
Elytra half longer than wide, EL/EW 1.49–1.53 (1.51), wide at bases, slightly wider than pronotum, EW/PW 1.14– 1.19 (1.17), parallel-sided, very slightly narrower at humeri than behind. Striae deep, very distinctly crenulate rather than punctate, striae 8, 9, and often also 7 in basal half, finely punctate, stria 7 very shallow to obliterate in basal third. Intervals very convex, costate apically. Stria 5 (= apical section of stria 7) with two apical setae.
Ventral side: sides of meso- and metathorax, and abdomen laterally coarsely and densely punctate; propleura mesally, mesepisterna, abdominal sternites in basal halves more finely punctate along middle, very finely and densely strigose along extreme bases.
Aedeagus (Figs 108–109, 114, 120–121): median lobe with transverse basal plication short and apex nearly straight in lateral view. Left paramere narrow. Internal sac distinctive, with sclerotized patches confined to apical three fifths.
GEOGRAPHIC DISTRIBUTION. Cambodia and southern Vietnam.
