description: [38] Parena (Parena) dorae Basilewsky, 1955
Habitus: Fig. 73B.
Basilewsky, 1955: 129 (type locality: Angola, Dundo; holotype in MRAC).
Type material examined. Parena dorae Basilewsky: Holotype (MRAC, Fig. 73B): female, body length = 9.1 mm, pin mounted, " HOLOTYPUS " [red label]; " Angola: Dundo / II. 1948 / A. de Barros Machado", " 411.6 ", " Parena / Dorae n.sp. / P. Basilewsky det., 19 54 ".
Comparisons. This species differs from all other species of subgenus Parena by the combination of dorsum reddish brown with distinct lustre, elytra without pattern, antennae distinctly bicolor; pronotum with lateral margins strongly sinuate before posterior angles; postgenae with suborbital setae; elytra disc shallowly depressed. Among all African species, this species is most similar to P. stigmatica, but can be distinguished from the latter species by its smaller size, lighter color, elytra with shallower depressions, and antennae bicolored.
Description. Body length 9.1 mm. Dorsum reddish brown, strongly polished; basal four antennomeres yellowish brown, apical ones nearly black; pronotal disc dark brown, distinctly darker than the anterior, posterior and lateral regions; elytra largely brown, base of inner intervals darker, but not forming distinct pattern; venter and legs yellowish brown, tarsi slightly darker. Vertex with sparse fine punctures; postgenae with suborbital setae; mentum with a pair of median setae which are slightly shorter than the terminal labial palpomere. Pronotum sub-quadrate, PW/PL = 1.49, slightly wider than head, PW/HW = 1.07; lateral margins indistinctly angulate at anterior third, strongly sinuate before posterior angles; posterior angles nearly rectangular, slightly pointed outwards; lateral explanations wide; disc with very sparse fine punctures and transverse wrinkles. Elytra slightly dilated to apex; with very shallow isodiametric microsculpture, visible only near base; striae shallowly incised, with dense and fine puncture rows, punctures absent near elytral apices; intervals distinctly punctate, similar to punctures in striae, even intervals evidently convex near base; discal depression large and very shallow, nearly round, at anterior third of intervals 3 to 5; apical truncation rounded, outer apical angles completely rounded; sutural angles not pointed. Apex of abdominal sternite VII straight in females, with two setae on each side. Gonocoxite II of ovipositor nearly quadrate, length slightly greater than basal width, apex concave, inner apical angle strongly pointed; with two ensiform setae on outer and inner apical angles respectively. Male unknown.
Distribution (Map 12, green). Only known from the type locality Dundo in northeastern Angola.
