Type material examined.
Holotype (female): "Suriname: Sipaliwini District: CSNR: Tafelberg Summit, Arrowhead Basin; flotation of wet moss on rocks; 20.viii.2013; leg. Short and Bloom; SR13-0820-04A" (NZCS).
Differential diagnosis.
Tobochares kolokoe can be recognized by its strongly convex body in lateral view (Fig. 9E View Figure 9 ), accompanied by elytral punctation uniform in size and degree of impression, not impressed to form elytral striae; the serial punctures are seemingly aligned in rows and the interserial punctures are somewhat irregularly distributed and moderately dense (in one or two rows, e.g., Fig. 3H View Figure 3 ). The general habitus and punctation of T. kolokoe are similar to those of T. arawak , T. canaima , and T. kappel . In T. arawak and T. canaima the interserial punctures are highly dense (forming two or three irregular rows, Fig. 3I View Figure 3 ). In T. kolokoe only the anterolateral margins of the pronotum are slightly paler than the general coloration of the pronotum and the legs are reddish brown in coloration (Fig. 9E, F View Figure 9 ), whereas in T. kappel the coloration of pronotum and elytra gradually becomes paler (orange) towards the outer margins (Fig. 9B View Figure 9 ), and the legs are orange in color (Fig. 9C View Figure 9 ). In addition, the serial punctures become more impressed along the postero-lateral areas of the elytra in T. kolokoe (Fig. 9E View Figure 9 ), whereas in T. kappel the serial punctures are equally impressed along the entire surface of the elytra (Fig. 9B View Figure 9 ).
Description.
Size and form: Body length 1.9 mm. Body elongate oval, strongly convex (Fig. 9E View Figure 9 ). Color and punctation: Dorsal and ventral surfaces of body dark brown, with prothorax (especially its anterolateral margins) slightly paler (Fig. 9D, E View Figure 9 ); mouthparts yellow (especially maxillary palps) to orange brown; antennae yellowish brown; legs orange brown with paler (yellow) tarsi (Fig. 9F View Figure 9 ). Ground punctation on head, pronotum and elytra moderately marked. Head: Eyes in dorsal view with anterior margin oblique (anteriorly directed; e.g., Fig. 2D View Figure 2 ), and outer margins slightly bulging from outline of head; in lateral view, eyes not emarginate (e.g., Fig. 2E View Figure 2 ). Thorax: Elytral punctation uniform in size and degree of impression, not impressed to form elytral striae (Fig. 9D View Figure 9 ); serial punctures seemingly aligned in rows; interserial punctures somewhat irregularly distributed in one or two rows (e.g., Fig. 3H View Figure 3 ). Metafemora mostly glabrous on anterior face (Fig. 9F View Figure 9 ). Elevation of mesoventrite forming a very low transverse carina (Fig. 9F View Figure 9 ). Metaventrite with distinct median, longitudinal, narrow glabrous area extending along posterior half (Fig. 9F View Figure 9 ). Abdomen: Abdominal ventrites uniformly and very densely pubescent (Fig. 9F View Figure 9 ).
Etymology.
Noun in apposition. Named with the Surinamese word Tobochares kolokoe meaning lucky, as this species is known from a single female specimen.
Distribution.
This species is only known from the summit of Tafelberg Tepui, a low-elevation sandstone massif in the center of Suriname (Fig. 13 View Figure 13 ).
Life history.
The lone specimen of this species was collected by floating saturated moss that was growing on rocks by a waterfall. The males of this species remain unknown.
