26. Anteon mcguirkae sp. nov. *

( Figs 3C )

Type material. HOLOTYPE: ♀, KENYA: NYANZA: Ruma National Park , near Kamato Gate, 0.64725°S 34.33595°E, 1264 m, 10–18.xii.2005, Malaise trap in open grass-woodland, R. Copeland leg. ( NMKE).

Diagnosis. Female fully winged, with head granulated, not reticulate rugose; face without two lateral keels along orbits directed towards antennal toruli; mesosoma black, except prothorax completely yellow-testaceous; posterior surface of pronotum with lateral sharp carinae separating disc from lateral regions; scutum granulated, with posterior third and part of lateral regions reticulate rugose; notauli very shortly visible near anterior margin of scutum; posterior surface of propodeum without longitudinal keels; forewing hyaline, without dark transverse bands, with distal part of stigmal vein less than 0.5 as long as proximal part; segment 4 of protarsus longer than basal part of segment 5 (7: 5); segment 5 of protarsus with inner side curvilinear and with distinct apical region ( Fig. 3C ).

Description. Female. Fully winged; length 2.3 mm. Head brown-ferruginous, except mandible testaceous; antenna testaceous-brown, except segments 1–2 testaceous; propleura and pronotum yellow-testaceous; rest of mesosoma black; metasoma testaceous-brown; legs testaceous, except stalk of hind femur brown. Antenna clavate; antennal segments in following proportions: 8: 4.5: 6: 5: 5: 5: 4.5: 4.5: 4.5: 5.5. Head convex, dull, almost completely hairless, strongly granulated; frontal line complete; face without lateral keels around orbits directed towards antennal toruli; occipital carina complete; POL = 5.5; OL = 3; OOL = 4; OPL = 4.5; TL = 5; greatest breadth of posterior ocellus shorter than OL (3: 2). Pronotum anteriorly crossed by weak transverse impression, dull, granulated; posterior surface granulated, dull, slightly shorter than scutum (10: 11); posterior surface of pronotum with lateral sharp carinas separating disc from lateral regions; pronotal tubercle reaching tegula. Scutum dull, completely granulated, with some rugosities near posterior margin and on lateral regions. Notauli very shortly visible near anterior margin of scutum. Scutellum dull, granulated. Metanotum shiny, rugose. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface dull, reticulate rugose; posterior surface dull, reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein much shorter than proximal part (2: 8). Protarsal segments in following proportions: 6: 2: 3: 7: 15. Segment 4 of protarsus longer than basal part of segment 5 (7: 5). Enlarged claw ( Fig. 3C ) with one proximal prominence bearing one long bristle. Segment 5 of protarsus ( Fig. 3C ) with basal part much shorter than distal part, with 2 rows of 10 + 13 lamellae; distal apex with 4 lamellae. Tibial spurs 1/1/2.

Male. Unknown.

Differential diagnosis. Based on the characters summarized in the above diagnosis, in the Afrotropical Region the new species is similar to Anteon variegatum Olmi, 2006 . The main differences between these two species can be summarized in the following key:

1 Face with two lateral keels along orbits directed towards antennal toruli; scutum completely granulated; posterior surface of pronotum with lateral borders rounded; prothorax black, except some regions testaceous. ................................. A. variegatum Olmi, 2006

– Face without two lateral keels along orbits directed towards antennal toruli; scutum granulated, with posterior third and part of lateral regions reticulate rugose; posterior surface of pronotum with lateral sharp carinas separating disc from lateral regions; prothorax completely yellow-testaceous. ..................................................... A. mcguirkae sp. nov.

Hosts. Unknown.

Etymology. This species is named after my (RSC) dear friend Mary Ellen (Mellen) McGuirk.

Distribution. Only known in the type locality.
