Lycocerus costipennis sp. nov.

Figs. 9 , 51–53 .

Type locality. Southern Vietnam, Dà Lat province, Cam Ly area.

Type material. Holotype ( NHMB), male, “ Vietnam, Da Lat [= Dà Lat province], Cam Ly area, rainforest, swept & beaten [white label, printed] / No. 691, 4.XI.1994, S. Mahunka, Gy. Sziráky & L. Zombon [white label, printed]”.

Description. Coloration ( Fig. 9 ). Head yellow, mandibles ferrugineous, maxillary palpi and antennae sepia. Pro- and mesothorax and elytra yellow, ventral side of abdomen and legs excluding yellow procoxae and last abdominal segment chestnut brown to sepia.

Male. Eyes rather large and protruding, head across eyes ca as wide as pronotum, sides of head behind eyes straight, converging posteriorly. Antennae reaching ca three fourth of elytral length, filiform, antennomeres without visible impressions. Surface of head almost impunctate, with sparse long, decumbent pubescence, semilustrous. Pronotum wider than long by ca one fifth, anterior margin moderately convex, anterior corners rounded, lateral margins straight, slightly diverging posteriorly, posterior corners nearly rectangular, obtuse, posterior margin straight. Surface of pronotum very finely imbricate-punctate, with fine, short, yellow recumbent pubescence, matt. Claws simple. Elytra very slightly dilated posteriorly, elytral venation well developed, costate, surface of elytra very finely imbricate-punctate, with short, fine, semirecumbent yellow pubescence, matt, almost velvety. Aedeagus as in Figs. 51–53 .

Female unknown.

Length (male). 8.1 mm.

Differential diagnosis. Lycocerus costipennis sp. nov. is similar in body form and coloration to Lycocerus pacholatkoi sp. nov., from which it differs by only slightly indicated pronotal impressions, distinctly costate elytra and shorter, narrower laterophyses in lateral view.

Etymology. Derived from Latin costa = rib and penna = wing, named in the reference to its remarkably costate elytra.

Distribution. Southern Vietnam.
