Macroderes arrowi Janssens, 1939 

( Figs. 4View FIGURES 3–6, 59View FIGURES 58–63, 70View FIGURES 70–75)

Macroderes arrowi Janssens, 1939: 26  ; Ferreira 1969: 320; Frolov & Scholtz 2005: 389.

Type locality. South Africa, Cape Prov, 11 Km N v Rhynsdorp [Vanrhynsdorp: 31°37'S 18°44'E]GoogleMaps  .

Type material examined. None. Type series is deposited in IRSNB ( Frolov & Scholtz 2005).

Additional material examined. 2 ♂♂ and 2 ♀♀ ( UPSA): “ RSA / Western Cape Prov / 11 Km / N of Vanthynsdorp / A. Frolov & C. Deschodt leg // AF-00 45 (25) / 5–11. IX. 2003 / S 31. 3028.28° E 018.4302.56°”  ; 2 ♀♀ ( UPSA): “ South Africa / Western Cape Prov / 124 km N of / Sandveld / S31.49859° E018.71642° / 15. 8. 2015 / C. Deschodt & W. P. Strümpher leg”GoogleMaps  .

Size range. Males length: 9.9–11.7 mm, width: 6.3–8.3 mm; females length: 9.7–10.5 mm, width: 6.5–7.7 mm.

Differential diagnosis. Due to it is carinate margins of elytra ( Fig. 70View FIGURES 70–75) M. arrowi  resembles M. foveatus  , M. cornutus  and M. greeni  , however, it can be easily distinguished from the two former species as it lacks the deep triangular concavity at the base of the pronotum ( Fig. 4View FIGURES 3–6) and from all others by having a granular pronotum ( Fig. 59View FIGURES 58–63) instead of rounded punctures found in M. greeni  and longitudinal punctures in M. cornutus  and M. foveatus  .

Habitat and distribution. So far this species is only known from Vanrhynsdorp and Sandveld areas ( Fig. 2). The two localities are situated in the Western Cape Province. Vanrhynsdorp is an arid area close to Namaqualand’s coast. The area is covered by succulent vegetation and characterised by rather humid climate and low annual rainfall. Sandveld situated to the west of the Cedarberg Mountains and is characterised by a rich biodiversity of animals and plants.
