Anteon alteri sp. nov. * ( Figs 4C ) Type material. HOLOTYPE : ♀ , KENYA : NYANZA: Ruma National Park , near Kamato Gate , 0.64725°S 34.33595°E , 1264 m , 18.xii.2005 – 1.i.2006 , Malaise trap , in open grass woodland, R. Copeland leg. ( NMKE ). Diagnosis. Female fully winged; head with OL shorter than POL; mesosoma black; scutum rugose and irregularly striate, except median region smooth, punctate, unsculptured among punctures, with anterior third reticulate rugose; posterior surface of propodeum with two longitudinal keels, with median area as rugose as lateral areas; forewing hyaline, without dark transverse bands, with distal part of stigmal vein much shorter than proximal part (4: 12); segment 4 of protarsus less than 0.5 as long as basal part of segment 5. Description. Female. Fully winged; length 3.5 mm . Head black, except mandible testaceous; antenna brown, except segments 1–3 testaceous; mesosoma black; gaster brown; tegulae testaceous; legs testaceous, except basal region of metacoxa brown. Antennal segments in following proportions: 14: 7: 8: 6: 7: 7: 8: 7: 7: 9. Head dull, completely reticulate rugose; frontal line complete; occipital carina complete; POL = 8; OL = 5; OOL = 6; OPL = 8; TL = 5; greatest breadth of posterior ocelli shorter than TL (3: 5). Pronotum shiny, reticulate rugose, except posterior margin smooth; posterior surface much shorter than scutum (5: 20); pronotal tubercle reaching tegula. Scutum shiny, rugose and irregularly striate, except median region smooth, punctate, unsculptured among punctures, with anterior third reticulate rugose. Notauli incomplete, hardly visible, reaching about 0.5 length of scutum. Scutellum and metanotum shiny, punctate, unsculptured among punctures. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface reticulate rugose, with two longitudinal keels and median area as rugose as lateral areas. Forewing hyaline, without dark transverse band beneath pterostigma; distal part of stigmal vein much shorter than proximal part (4: 12). Protarsal segments in following proportions: 12: 2: 3: 3: 12; segments 3 and 4 of protarsus produced into hooks; segment 4 of protarsus less than 0.5 as long as basal part of segment 5 (3: 9). Enlarged claw ( Fig. 4C ) slightly longer than segment 5, with proximal prominence bearing one long bristle. Segment 5 of protarsus ( Fig. 4C ) with basal part much longer than apical part (9: 3), with some proximal and medial bristles in addition to one lamella; distal apex with 5 lamellae. Tibial spurs 1/1/2. Male . Unknown. Differential diagnosis. With reference to the characters summarized in the above diagnosis, in the Afrotropical Region the new species is similar to Anteon rufonigrum Olmi, 1984 and A. shimbanum Olmi, 2011 in OLMI & COPELAND (2011) . The main difference among these species regards the forewing: with one dark transverse band beneath the pterostigma in A. rufonigrum and A. shimbanum ; hyaline, without dark transverse bands, in A. alteri . Other differences regard the colour (head and mesosoma mostly testaceous-reddish in A. rufonigrum , black in A. alteri and A. shimbanum ) and the notauli (absent in A. rufonigrum and A. shimbanum , reaching about 0.5 length of scutum in A. alteri ). Etymology. This species is named after the collector’s (RSC) longtime friend, the noted psychologist Robert (Bobby) Alter. Hosts. Unknown. Distribution. Only known from the type locality.
