Pneuminion tubum View in CoL new species
( Figures 5 View FIGURE 5 , 15, 25 View FIGURES 23 – 25 )
Type Material. Holotype (male): South Africa: S. W. Cape Mts., Hawequas SE, 1100m, 33.41S 19.06E, water coll. in rapid, 5.xi.1973, EndrödyYounga (#203); deposited in the TMSA.
Diagnosis. A relatively smooth species, especially on the head and elytra. Recognized also by the transversely convex form, the sulciform impressions of the frons, the small punctures on the pronotal reliefs appearing paired, and the relatively smooth, nongranulate elytra ( Fig. 5 View FIGURE 5 ).
Description. Size (mm x 100; length/width): body (length to elytral apices) 152/67, head 30/44, pronotum 37/56, elytra 93/67.
Dorsum dark brown to piceus on head and pronotum, elytra, legs and maxillary palpi brown; dorsal setae conspicuous, very slender, testaceous. Labrum and clypeus weakly shining, finely sparsely punctate. Frons disc punctate, interpunctal surface smooth, shining, punctures separated by ca. 1–2.5xpd. Fovea in front of each ocellus narrow, oblique groove, about as wide as ocellus.
Pronotum dull, densely moderately finely punctate, punctures on reliefs each with short, granulebased seta, granule dividing puncture in half, punctures therefore appearing paired, most oriented transversely or subtransversely, some punctures near base only partially divided by granule, therefore heartshaped; oblique anterior fovea on each side shallowly connecting to midlongitudinal fovea; posterior Ushaped fovea welldeveloped; setae at lateral margin flat on cuticle in dry specimens.
Elytra with setae of series and interseries almost equally developed, resulting in narrowly separated unilinear rows of very fine setae, about 18 on each elytron; setae of intervals slightly more apparent than those of series; granule at base of each seta very small, if perceptible; serial punctures separated by about puncture diameter, slightly narrower than intervals, cuticle moderately shining at side of punctures; intervals very slightly raised; explanate margin very narrow.
Aedeagus: mainpiece length 43, total length 51; duct sharply Sshaped, gradually thickened from about midlength to apex, tip expanded; mainpiece bladeshaped, lacking ridge/groove; paramere setae comparatively sparse, clustered distally on right paramere; right paramere attaining level of apex of mainpiece ( Fig. 15).
Etymology. Named in reference to the tubelike duct of the aedeagus.
