Parasthetops parallelus new species

( Figs. 30 , 33 , 93 )

Type Material. Holotype (male): South Africa: Northern Cape Province, No. Cape, Richtersveld, Oemsberg , river stones, 28° 27' S, 17° 10' E, 23 September 1991, Endrödy­Younga (#2791). Deposited in the TMSA . Paratypes: Same data as holotype (13 TMSA) .

Differential Diagnosis. Members of P. parallelus are differentiated from the other members of the camurus group by the large body size (ca. 2.09 mm), the parallel­sided elytra, and the weakly developed posterior declivity of the elytra ( Fig. 30 ). The aedeagus of P. parallelus is quite dissimilar from those of P. camurus and P. reflexus , the other members of the camurus group ( Figs. 33–35 ).

Description. Size (length/width, mm) holotype: body (length to elytral apices) 2.09/0.76; head 0.35/ 0.45; pronotum 0.44/0.60; elytra 1.31 /0.76. Dorsum of head and pronotum dark brown, elytra brown, legs light brown, maxillary palpi testaceous except distal 1/2 of last mere dark brown, venter dark brown. Submentum and mentum microreticulate, dull, sparsely punctulate.

Head with labrum microreticulate and finely punctulate, weakly shining. Clypeus and frons disc very effacedly microreticulate, weakly shining, moderately densely, moderately coarsely punctate, punctures separated by about 1–4xpd, size of largest punctures about 1xef or slightly less. Frons more strongly microreticulate laterally and in deep anteocellar sulci. Ocelli distinct.

Pronotum cordate, widest in front of middle; anterior angles obtuse, posterior rectangular; sides finely margined, weakly crenulate; anterior margin shallowly arcuate over median 2/3, with narrow hyaline border; discal reliefs shining, very finely, very sparsely punctulate, punctures much finer and sparser than frons punctures, interstices ca. 6–10xpd; anteriorly and posteriorly punctures much larger, about 4xef; with foveae as follow: median anterior elongate and smaller posterior, moderately shallowly confluent; a small anterior and larger, deeper oval posterior admedian; and a large anterior and small deep posterior adlateral on each side; foveae effacedly microreticulate; punctures on discal reliefs without discernible setae.

Elytra parallel­sided, comparatively elongate, rather flattened, posterior declivity very gradual, almost obsolete, apices truncate; sutural apices rectangular; sides smooth, weakly explanate. Serial punctures moderately large and deep, about 1xpd of largest pronotal punctures, interstices on disc about 1xpd; without granules. Series one very weakly striate­impressed in posterior 1/2. Intervals flat or very weakly rounded, width on disc about 1–2xpd. Most punctures with very short, fine seta.

Metaventral disc rather flat, with very shallow, almost obsolete impression in basal 1/2. Thoracic ventrites and abdominal ventrites 1–5 clothed with dense setae except glabrous midlongitudinal prosternal ridge, glabrous dull mesoventral plaques and small glabrous inverted V­shaped basomedian area on metaventrite in front of intercoxal sternite. Ventrite 6 shining, with sparse setigerous punctures across distal 1/2.

Females with explanate margin of elytra very similar to males.

Wings fully developed on holotype.

Aedeagus length ca. 0.43 mm, flagellum 0.23 mm; main­piece very asymmetrical, parameres widened apically ( Fig. 33 ).

Etymology. Named in reference to the parallel­sided elytra.

Distribution. Currently known only from the type locality in the Oemsberg Mountains of western Northern Cape Province ( Fig. 93 ).
