Fig. 28

Etymology: This species is named after the type locality, Karibib.

Description:

Female.

Head brown, with mandibles, clypeus and anterior region of face testaceous; antennae testaceous; mesosoma testaceous-reddish, with propleura and mesopleura darkened; gaster brown; legs testaceous, with coxae and clubs of hind femora brown. Antennae clavate; antennomeres of holotype in following proportions: 6:4:5.5:4:3:3:2.5:4:3:5. Head excavated, shiny, slightly granulated; temples distinct; frontal line incomplete, only present in posterior half of face; occipital carina absent; POL = 1; OL = 1; OOL = 6.5; greatest diameter of posterior ocelli = 1. Maxillary palpi missing in holotype; labial palpi 2-segmented. Pronotum crossed by strong transverse impression, shiny, without sculpture. Scutum less than twice as long as broad, shiny, without lateral points. Scutellum shiny, smooth, circular, slightly inclined. Metanotum very short, inclined, transversely striate, not hollow behind scutellum. Metathorax + propodeum shiny, with median longitudinal furrow, with posterior surface transversely striate; anterior surface of metathorax + propodeum shiny, with a few median longitudinal striae. Mesopleura and metapleura transversely striate. Meso-metapleural suture distinct and complete. Fore tarsal segments in following proportions: 9:2:3:8:14. Enlarged claw ( Fig. 28 ) with small subapical tooth, 4 large lamellae and 1 hair. Segment 5 of front tarsus ( Fig. 28 ) with 1 row of 12 lamellae; distal apex with group of about 8 lamellae.

Holotype: ^“ NAMIBIA: 17 km S Karibib , along Road C32, 8.iii.2006, M. Olmi ”; [red] “ Gonatopus karibibensis sp. n. M. Olmi det. 2006, ^” (NNIC).

Hosts: In Namibia, the holotype has been observed attacking Paradorydium spatulatum (Naudé) (Cicadellidae) .

Comments: G. karibibensis belongs to the G. incognitus group. The female is similar to that of G. tananarivei Olmi, 1984 , but it may be distinguished by the enlarged claw (with peg-like hairs in G. tananarivei ; with lamellae in G. karibibensis ) and the colour of mesosoma (black in G. tananarivei , testaceous-reddish in G. karibibensis ).
