Aleiodes (Hemigyroneuron) pappi Butcher and Quicke sp. nov.

( Figures 20 , 21 )

Material examined

Holotype. Female , “ KENYA, Mt. Elgon Nat.P., near Chepnyalil cave, dry evergreen montane forest, 2500m; singled and swept from the vegetation, 28.i.1992, No. 509. O. Merkl & G. Várkonyi ” ( HNHM).

Morphology

Length of body 8.2mm, of fore wing 8.5 mm.

Head. (Antenna broken); head subtransverse, 1.5 times wider than maximally long in dorsal view; width of head 2.9 times shortest distance between eyes; height of eye 2 times shortest distance between eyes; frons virtually flat, finely and weakly aciculate, without mid-longitudinal suture or pit in front of anterior ocellus, with distinct lateral carina nearly paralleling margin of eye at emargination; ocelli very large, posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 4.0: 8.2: 1.0; occiput largely rugulose but aciculate behind stemmaticum; occipital carina obliterated medially.

Mesosoma . Mesoscutum coriaceous-rugulose and densely short-setose; notauli hardly indicated; mesopleuron not impressed, densely setose with punctures at bases of setae, with some faint vertical striation medially; prepectal carina complete; scutellar sulcus with five carinae between the outer ones; scutellum finely coriaceous, and with lateral carinae (as extensions of lateral carinae of scutellar sulcus) present on anterior half; median area of metanotum largely smooth with weak indication of mid-longitudinal sulcus; propodeum rugulose with indication of parallel ridges arising from midline and converging anteriorly, with complete mid-longitudinal carina and strong crenulae at posterior margin, with sublateral posterior crenulation being long and extending over very weak postero-lateral tubercle.

Fore wing. Subbasal cell densely setose on basal 0.75, weakly narrowing before distal (largely) glabrous expansion; with densely setose sclerome located in band of setae running between setose basal part of cell and posterior tip of vein cu-a; vein 1-CU1 0.33 times length of 2-CU1; vein cu-a straight, vertical, distinctly expanded posteriorly; length of veins r: 3-SR: SR1 = 1.0: 1.9: 4.5; vein m-cu approximately 2.5 times length of 2-SR+M, forming angle of 110 ◦ with 3-CU1; vein 2-M 2.8 times length of r-m.

Hind wing. Vein M+CU 1.15 times length of vein 1-M; vein 2-SC+R short longitudinal; basal and subbasal cells and basal part of discal+subdiscal cell evenly setose.

Claws. With pecten of at least two strong teeth extending just beyond middle of basal lobe.

Metasoma. Tergites 1, 2 and basal 0.7 of tergite 3 longitudinally striate with irregular punctures between the striae; 2nd tergite 1.3 times wider than medially long, 2.6 times longer than 3rd.

Colouration

Black-brown except the following which are yellow: malar region; mandibles (except tips); palps; dorsum of mesosoma including tegula and propodeum; metasomal tergites 1, 2 and basal part of 3rd.

Etymology

Named in honour of Jenö Papp in recognition of his major contribution to braconid systematics.
