( Fig. 28 )

Therates probsti baolocensis Wiesner 1996: 506 - 508 , f. 7.

Type depository. Holotype female in JWGC.

Type status. Holotype female! Type labels: “S. VIETNAM, 5./6. 1994, Bao loc, leg., Dembicky and Pacholatko ” [printed, yellow]; “ THERATES , probsti baolocensis, nov. subspec., det. J. Wiesner 96” [printed, white]; “HOLOTYPUS” [printed, red, with double black borders].

Nomenclatural note. Wiesner (1996: 507) tentatively placed baolocensis as a subspecies of probsti Wiesner 1988 “unless the corresponding male has been studied”. Subsequently, one male and one female of this species were available for study, examination of the male aedeagus shows significant difference to justify its elevation to specific rank.

Diagnosis. Distinguished by the combination of broad humeral lunule and large, acutely angled central dot.

Re-description. Size: Total length (without labrum) 7.5 mm- 8.4 mm, (mean= 7.9 mm, n=3). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 34 , female Fig. 35 ) as wide as long, yellowish, with six apical teeth and one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind elytral shoulders in the male, somewhat shorter in the females, scape with a single apical bristle, antennomeres 2 to 5 glabrous, antennomeres 6 to 11 finely and evenly pubescent; scape yellowish above, black on underside, remaining antennomeres blackish. Clypeus glabrous. Frons smooth, with a transverse shallow furrow in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, as long as wide, constricted in front and at back, transverse furrows strong, middle line and lateral lines nearly obsolete, middle line with several transverse short branches. Elytra: Shining black, with basal and apical humps, distinctly punctate in front, nearly absent in apical half ( Figs. 29, 30 ). Apex with angular lateral and sutural corner, recurved between. Maculations composed of a slender brownish yellow humeral lunule which is enlarged distally, a brownish yellow basal dot, and a large brownish yellow central dot that is acutely angled outwards toward the front ( Figs. 31, 32 ). Humeral lunule and basal dot are connected at the base. Apex with a yellow dot at the suture, not reaching the apical humps. Ventral aspect: Venter black. Legs yellowish, tibiae and tarsomeres somewhat darkened distally. Aedeagus: ( Fig. 33 ) curved, with produced tip, total length 1.8 mm.

Distribution. Vietnam (Lam Dong).

Localities. VIETNAM, Lam Dong, 15 km SW Bao Loc , 22.-24.iv. 1995, 900 m ( ZSMC) , Lam Dong, near Bao Lok , 6.v.1997 ( JWCG) .
