Type material. Holotype ♂: “ Kaokoland ( Namibia), 4 km E Orumana, 18°1'S 13°50'E, 24.ii.1990, E. Marais & J. Irish leg.” ( ZMHB).GoogleMaps 

Diagnosis. Blepharidina himba  sp. nov. shows a clear affinity with B. matabelelandensis  sp. nov., with which it shares similar size, habitus, and color pattern ( Figs 7View FIGURES 1–10, 14View FIGURES 11–19) and a very slender aedeagus, with laterally widely rounded apical part in ventral view ( Figs 43View FIGURES 38–43, 50View FIGURES 50–54). However, B. himba  sp. nov. can be easily distinguishable from B. matabelelandensis  sp. nov. by: the lighter integuments; the different arrangement of the pronotal punctures ( Figs 21, 24View FIGURES 20–25), with two lateral groups and an elongate medial group (three lateral groups and a small basal medial group in B. matabelelandensis  sp. nov.); the aedeagus tapered from base to subapical part (fusiform in B. matabelelandensis  sp. nov.) ( Figs 43View FIGURES 38–43, 50View FIGURES 50–54).

Description of the holotype (♂). Body elliptical-elongate, rather convex ( Fig. 7View FIGURES 1–10); LB = 7.31 mm; maximum pronotal width (WP = 2.81 mm) in basal third; maximum elytral width (WE = 3.81 mm) in middle. Head brown with yellowish antennae; pronotum yellow with brown patches mostly on groups and lines of punctures; elytra mostly yellow, but blackish on striae of punctures and part of interstriae; legs brown, with paler tarsi. Head distinctly pubescent, roughly and densely punctate; frontal grooves short, distinctly impressed near upper ocular margin; frontal tubercles small, flat, paler than head; interantennal space distinctly wider than length of first antennomere; upper interocular space wider than transverse ocular width ( Fig. 21View FIGURES 20–25); antennae about as long as half body length (LAN = 3.63 mm; LAN/LB = 0.50); LA: 100:39:67:83:83:78:78:72:72:72:83. Pronotum ( Fig. 21View FIGURES 20–25) subrectangular, distinctly transverse (LP = 1.56 mm; WP/LP = 1.80), with clearly sinuate lateral margin; anterior margin slightly thicker than basal margin, and clearly sinuate laterally; anterior angles distinctly prominent and slightly rounded anteriorly, pointed laterally; pronotal surface with lines and groups of differently sized punctures, also with a longitudinal line of punctures in middle; pronotal base with two lateral, distinctly impressed longitudinal striae. Scutellum brown, subrounded, moderately elongate. Elytra moderately elongate (LE = 5.69 mm; WE/LE = 0.67; LE/LP = 3.64), subparallel laterally, jointly rounded and entirely covering pygidium posteriorly; punctation deeply impressed, arranged in 9 (+ 1 scutellar) regular rows; interstriae distinctly carinate laterally and posteriorly. First pro- and mesotarsomeres distinctly dilated; tarsal claws bifid. Ventral parts brown; last abdominal ventrite without distinctive preapical impressions. Aedeagus (LAED = 3.50 mm; LE/LAED = 1.63) ( Fig. 43View FIGURES 38–43) in ventral view slender and tapered from base to subapical part; apical part laterally widely rounded, with a small median tooth; ventral sulcus deep, open towards basal part; in lateral view, aedeagus straight in basal 2/3s, then slightly curved dorsally, with apex ventrally bent; dorsal ligula connected to about apical fourth, with slightly carinate basal surface.

Etymology. The female specific epithet is after Himba people, who inhabit the north-western part of Namibia, where the species was collected.

Distribution. Namibia ( Fig. 68View FIGURES 68–69). Possibly Central Afrotropical (CAT) chorotype.

Ecological notes. Not available. The collection site falls within the area of Mopane Savanna vegetation (belonging to the Tropical Lowland Grassland, Savanna & Shrubland formation).
