Colophon struempheri Jacobs & Scholtz , new species

( Fig 3 a-d; Table 1).

Type material. Holotype: (1♂: ISAM); Paratypes: (1♂, 1♀: UPSA).

Diagnosis. Colophon struempheri is most similar to C. deschodti , but can be distinguished from the latter by the lack of median point or protuberance on the anterior margin of the head. Furthermore, C. deschodti has the mentum distinctly bifid, whereas C. struempheri has the mentum narrow and slightly bifid. Pairwise genetic distance from C. stokoei is 7.4% for COI ( Switala et al. 2014).

Holotype description. Colour: Black. Size: Male: length 19.8 mm, pronotal width: 10.3 mm, mandible length: 3.1 mm. Female: 15.6 mm, pronotal width: 8.7 mm. Head: Declivous in front but with a feeble indication of a definite anterior margin ( Table 1). Mandible: Apex of mandible deeply impressed on upper surface as in C. stokoei ; ventral process prominent, rectangular ( Table 1). Mentum: Anterior surface narrow, not excavated; anterior margin simply bifid; ventral surface deeply impressed on either side of a projecting median ridge ( Table 1). Legs: Protibia similar to C. stokoei , but less curved and less robust, the two apical teeth sharper and the extension is less deep ( Fig. 3 d). Male genitalia: As in C. stokoei .

Variation. Size: length 19.86–20.08 mm, pronotal width 10.29–10.70 mm (n = 2). Female: Description as for C. stokoei ( Fig. 3 c).

Distribution. Hottentots Holland Mountains, Western Cape Province, South Africa.

Etymology. The species is named after Werner P. Strümpher in recognition of his contribution to the study of Colophon .
