16. Anteon crowleydelmanorum sp. nov. *

( Figs 2C )

Type material. HOLOTYPE: ♀, KENYA: WESTERN: Kakamega Forest, near Rondo Guesthouse , 0.22767°N 34.88533°E, 1630 m, 17–31.xii.2006, Malaise trap, set across small permament stream, R. Copeland leg. ( NMKE).

Diagnosis. Female fully winged, almost completely black, with head reticulate rugose; posterior surface of pronotum much shorter than scutum (3: 15); scutum and scutellum completely reticulate rugose; posterior surface of propodeum reticulate rugose, without longitudinal keels, with areolae very small, smaller than areolae of head; forewing with two dark transverse bands; segment 4 of protarsus at most 0.5 as long as basal part of segment 5.

Description. Female. Fully winged; length 2.6 mm. Head black, except mandibles testaceous; antenna brown, except segment 1 testaceous; mesosoma and metasoma black; legs brown. Antenna clavate; antennal segments in following proportions: 14: 6: 4.5: 3.5: 4: 4.5: 4.5: 4: 5: 7. Head convex, dull, strongly reticulate rugose; frontal line complete; face without lateral keels near orbits directed towards antennal toruli; occipital carina complete; POL = 7; OL = 5; OOL = 6; OPL = 4; TL = 3; greatest breadth of posterior ocellus about as long as TL. Pronotum anteriorly crossed by a slight transverse impression, dull, rugose; posterior surface rugose, much shorter than scutum (3: 15); pronotal tubercle reaching tegula. Scutum, scutellum and metanotum dull, completely strongly reticulate rugose. Notauli absent. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface dull, reticulate rugose; posterior surface dull, reticulate rugose, without longitudinal keels, with areolae very small, smaller than areolae of head. Forewing with two dark transverse bands; distal part of stigmal vein much shorter than proximal part (3: 8). Protarsal segments in following proportions: 8: 2: 2: 3: 10. Enlarged claw ( Fig. 2C ) with proximal prominence bearing one long bristle. Segment 5 of protarsus ( Fig. 2C ) with basal region much longer than distal region (8: 2), with many proximal and medial bristles (some bristles are thicker than others); distal apex with one lamella. Tibial spurs 1/1/2.

Male. Unknown.

Differential diagnosis. In reference to the characters summarized in the above diagnosis, in the Afrotropical Region the new species is similar to Anteon felice Olmi & Harten, 2006 . The main difference regards the sculpture of the scutellum: reticulate rugose in A. crowleydelmanorum and weakly granulated in A. felice . In addition, the areolae of the posterior surface of the propodeum are as large as those of the head in A. felice , smaller in A. crowleydelmanorum .

Etymology. This species is named after my (RSC) friends Maureen Crowley, the noted urban environmentalist, and Peter Delman, the exceptional teacher and artist, who also has a place in his heart for insects.

Hosts. Unknown.

Distribution. Only known from the type locality.
