Type Material. Holotype (male): South Africa: Western Cape Province, Cape, Cederberg, Eikenboom , river stones, elev. 900 m, 32° 27' S, 19° 10' E, 29 October 1981, Endrödy­Younga (#1906). Deposited in the TMSA GoogleMaps   . Paratypes (39): Western Cape Province, Same data as holotype (35 TMSA) GoogleMaps   ; Cape­Cederberg , jeep track, sifted marsh shore, elev. 1130 m, 32° 28' S, 19° 14' E, 7 November 1983, Endrödy­Younga (#2055) (1 TMSA) GoogleMaps   ; W. Cape, Cedarberg Pass , from river bed, 32° 23' S, 19° 6' E, 2 September 1979, Endrödy­Younga (#1629) (3 TMSA) GoogleMaps   .

Differential Diagnosis. Among truncatum   group members, individuals of M. granulovestum   are similar to those of M. brevigranum   in having granulose pronotal reliefs; differentiated therefrom by the proportionally

smaller prothorax and larger elytra ( Fig. 82 View FIGURE 82 ). The aedeagi of the two species also indicate a relationship ( Figs. 84, 85 View FIGURES 84–87 ).

Description. Size (length/width, mm) holotype: body (length to elytral apices) 1.73/0.69; head 0.33/ 0.42; pronotum 0.38/0.45; elytra 1.00/0.69. Dorsum and venter piceous to dark brown, maxillary palpi and legs dark brown.

Head dorsally markedly microreticulate, rugulose, dull; anteocellar sulci shallow. Ocelli distinct. Mentum and submentum markedly microreticulate.

Pronotum rugulose, dull; cordate, widest in front of middle; anterior angles obtuse, posterior rectangular; sides finely margined, feebly crenulate; anterior margin very shallowly arcuate over median 3/4, without hyaline border; 10 distinct foveae as follow: two median, an anterior elongate and smaller round posterior, shallowly confluent; a small round anterior and larger oval posterior admedian; and a large deep anterior and smaller posterior adlateral on each side; foveae microreticulate; each puncture with a fine short seta.

Elytra with sides weakly arcuate, apices truncate; sutural apices rectangular; sides smooth, weakly explanate. Serial punctures quite large at base, progressively finer apically, basal punctures separated by about 1xpd or less; each puncture with small granule at anterior margin; series 1 weakly striate­impressed in basal 1/2; at midlength with seven series between suture and carina; 5th and 6th series confluent in basal 1/3. Intervals, except 8th, weakly rounded, width on disc about 2xpd, each with unilinear row of granules, each about 1xef; 8th strongly costate. All punctures bearing a short fine seta.

Thoracic ventrites and abdominal ventrites 1–4 densely clothed with short setae, except glabrous proventral midlongitudinal ridge, mesoventral plaques, and small glabrous strongly shining triangular area basomedially on metaventrite. Metaventral disc with midlongitudinal groove. Abdominal ventrites as follow: 1st with submedian and sublateral basal carina on each side; 5th similarly clothed except narrow apical area glabrous and shining; males with 6th glabrous, shining, apicomedially very weakly emarginate, with posterior band of sparse slender setae; females with 6th sharply rounded apically, almost lobate, glabrous, posterior 1/2 with sparse slender setae.

Legs of male with two spiniform setae on apical protarsomere. Femora and tibiae effacedly microreticulate.

Females with elytral explanate margin slightly wider, elytral apices more widely, roundly truncate; pronotal anterior angles more produced than in males.

Wings fully developed on holotype and all dissected males.

Aedeagus length ca. 0.36 mm; main­piece straight in ventral view, with short apical process on left side; distal process large, markedly sinuate, in ventral view angled to left side; parameres extended beyond apex of main­piece ( Fig. 85 View FIGURES 84–87 ).

Etymology. Named in reference to the dorsal granulation and vestiture.

Distribution. Currently known from the Cederberg Mountains, western Western Cape Province ( Fig. 102 View FIGURES 101–102 ).
