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

( Figures 14 , 15 )

Material examined

Holotype. Female , Democratic Republic of Congo, “ CONGO / KIVU, Lwiro, 12- 12.1966 Dr Jilly Leg.” ( SMNH).

Paratype. Female, same data as holotype except 14 August 1966 ( SMNH) .

Morphology

Length of body 8.4–9.5 mm, and of fore wing 8.0– 9.8 mm.

Head. Antenna with 65 flagellomeres; terminal flagellomere acuminate; head transverse, 1.6 times wider than maximally long in dorsal view; width of head 3.15 times shortest distance between eyes; height of eye 2.0 times shortest distance between eyes; frons weakly depressed, smooth and shiny, without mid-longitudinal sulcus and without pit in front of anterior ocellus; posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.7: 5.5: 1.0; occiput and temples weakly aciculate to rugulose-punctate; occipital carina broadly interrupted medially.

Mesosoma . Mesoscutum finely aciculate-coriaceous, densely short-setose and with conspicuous punctures at bases of setae; posteriorly with some transverse rugosity between notauli; notauli weakly impressed but margined on inner side by fine ridge and with distinct line of crenulae; mesopleuron densely setose and smooth and shiny between setae, without concave area. Prepectal carina complete though weaker dorsally; scutellar sulcus with four carinae between the outer ones; scutellum entirely with fine longitudinal striation laterally, otherwise finely aciculate and with broad punctures at bases of setae; median area of metanotum sculptured and with complete but weak mid-longitudinal carina; propodeum foveate-rugulose with complete though irregular mid-longitudinal carina.

Fore wing. Subbasal cell densely setose on basal 0.75, weakly narrowed before largely glabrous distal part which contains a setose sclerome connected by band of setae to basal setose area but not to vein cu-a; vein 1-CU1 0.46 times length of 2-CU1; vein cu-a straight, nearly transverse, strongly expanded posteriorly; length of veins r: 3-SR: SR1 = 1.0: 2.2: 4.0; vein 2-M 3.5 times length of r-m; vein m-cu 2.3 times length of 2-SR+M, forming angle of 115 ◦ with 3-CU1.

Hind wing. Vein M+CU 1.4 times length of vein 1-M; vein 2-SC+R longitudinal; basal and subbasal cells and basal part of discal+subdiscal cell evenly setose.

Claws. With strong pecten of five teeth extending just beyond middle of basal lobe.

Metasoma. Tergites 1, 2 and basal 0.6 of tergite 3 finely longitudinally striate with irregular punctures between the striae, posterior of tergite 3 punctate; 2nd tergite 1.4 times wider than medially long, 1.3 times longer than 3rd.

Colouration

Head, antennae, body and legs black except posterior of scutellum, metanotum and propodeum (except two black marks on propodeum posterolaterally); wings yellow except apical 0.4 of fore wing grey with yellow spot around vein r-m and apical 0.25 of hind wing grey.

Etymology

Named after the junior author’s friend Dorothy Fenwick.
