Pneuminion natalensis View in CoL new species
( Figures 6 View FIGURE 6 , 16 View FIGURE 16 , 30 View FIGURES 29 – 30 )
Type Material. Holotype (male): South Africa: Natal, 75km WSW Estcourt, Cathedral Peaks For. Sta., 7–31.xii.79, S. & J. Peck, Meteorology Sta., LittleBerg, 1860m, malaise trough, 21–31.xii.79; deposited in the TMSA. Paratype: Same data as holotype, (1 TMSA).
Diagnosis. Similar to P. punctatum in dorsal sculpture, recognized by the more strongly sculptured, subrugulose pronotal foveae, the less rugulose frons foveae, the smaller elytral granules, the smaller elytral punctures, the more nearly equally developed rows of setae on the elytral series and intervals, and the shallower pronotal postocular emarginations ( Fig. 6 View FIGURE 6 ). Reliable determinations of the two species will be based on examination of the quite dissimilar male genitalia. The aedeagus of P. natalensis is most similar to that of P. v e l a m e n (refer to the diagnosis of that species).
Description. Size (mm x 100; length/width): body (length to elytral apices) 163/74, head 26/44, pronotum 37/61, elytra 104/74. Dorsum piceus, legs and maxillary palpi dark brown; dorsal setae conspicuous, especially on head and pronotum, whitish. Labrum and clypeus dull, micropunctulate, except shining on anterior margin of clypeus. Frons disc moderately coarsely punctate, most punctures heartshaped, interpunctal surface smooth, shining, punctures separated by ca. 1.5xpd; fovea in front of ocellus micropunctulate, medial margin moderately abrupt.
Pronotum rugulose in foveae and laterally, weakly shining on disc, dull laterally; punctures on reliefs small, ca. 0.25x size of heartshaped punctures in Ushaped fovea, separated by ca. 1–3xpd, each with short whitish, granulebased seta; interpunctal surfaces on relief smooth and shining; 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. Pronotal postocular emargination deeper and less symmetrical in females than males.
Elytra with setae of series and intervals very nearly equally developed, resulting in discrete, narrowly separated, unilinear rows of setae, about 18 on each elytron, each seta granulebased; serial punctures moderately large, slightly wider than intervals, separated serially by less than puncture diameter; explanate margin narrow in male, slightly wider in female.
Aedeagus: mainpiece length 44, total length 61; mainpiece distal portion with ridge/ groove to support duct and apex weakly hookshaped; duct very slender over distal onehalf ( Fig. 16 View FIGURE 16 ).
Etymology. Named in reference to the known geographical distribution.
