Blaiseus daklakensis Douglas , new species

( Figs. 10, 11 , 19 )

Material examined. Nine males.

Type material. Holotype: Male labeled: ‘‘ VIET NAM / BanMeThuot 500 m / 16– 18.v.1960 ’’; ‘‘ L.W. Quate / Collector’ ’; [red] ‘‘ HOLOTYPE / Blaiseus / daklakensis/ Douglas 2007,’’ with wing mounted on card and genitalia; genitalia in microvial attached to pin ( BPBM) . Paratypes: 7 males with the same label data as the holotype, all with the following paratype designation labels [yellow] ‘‘PARA- TYPE/ Blaiseus / daklakensis/ Douglas 2007’’ ( BPBM) .

Type locality: Vietnam, Dak Lak Province, Buon Me Thuot , elevation 500 m, approximately 12.68 ° N, 108.05E .

Non type material. One male ( BPBM), labeled: ‘‘ VIET NAM. 20 km / N. of Pleiku / 650 m. 9.V.1960 .’’

Diagnosis. Pterothorax: Scutellum with posterior apex pointed (Fig. 3); elytra with apices not upturned ( Fig. 11 ). Legs: Femora and tibiae expanded (fossorial); protibiae with posterior tooth at apex but not at midlength. Aedeagus: median lobe sides concave on basal 3/ 4 in dorsal view.

Description. Male: Length 5.3–6.3 mm. Integument red-brown to brown, without lighter patches on elytra. Head: Antennae reaching metacoxae; labrum concave in lateral profile, nasale with ovoid pits antero-mesad of antennal fossae similar in size to largest punctures on disk of pronotum. Prothorax: Posterior edge of pronotum with 2 apices mesally; hypomeron with hind edge sinuate immediately meso-ventrad of hind angles ( Fig. 1 ). Prosternum with ventral surface of prosternal process surface not carinate laterally. Pterothorax: Scutellum with posterior apex pointed (Fig. 3). Elytra not upturned at apex; interval 5 costate on apical third; epipleurae irregularly serrate. Hind wings with CuA1 not forked at junction with MP3+4. Legs: Femora and tibiae expanded (fossorial); protibiae with posterior tooth at apex but not at midlength; tarsomere 4 weakly lobed. Male genitalia: Aedeagus with median lobe broadest near apex, sides concave throughout basal 3/4 of free portion, not concave at apex ( Fig. 19 ); parameres with ventral apices about equal in length to dorsal (setose) lobes; inner parameres sclerotized.

Female: Unknown.

Comments. Evidence that this species is distinct from B. fujianus new species includes the concave (convex in B. fujianus Fleutiaux ) sides of the median lobe of the aedeagus.

Known from type locality and one other site (approximately 14.11 ° N, 107.92 ° E) 160 km northward in Gai Lai Province . The elevations from specimen labels indicate that the specimens were collected at plateau level, not on nearby forested peaks. This is the only Blaiseus species known from central Vietnam .
