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

( Figure 16 )

Material examined

Holotype male. “ SOUTH AFRICA, Tvl [ Transvaal ], Soutpan, Pretoria District. 25.24S 28.05E. 20.xi.1985 J.S. Donaldson ” ( SANU).

Morphology

Length of body 5.3 mm (but body strongly curled), and of fore wing 5.8 mm.

Head. (Antennae incomplete); head subtransverse, 1.5 times wider than maximally long in dorsal view; width of head 2.4 times shortest distance between eyes; height of eye 1.67 times shortest distance between eyes; frons rather deeply impressed, shiny with some longitudinal, posteriorly diverging striations and pit in front of anterior ocellus; posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 2.5: 4.0: 1.0; occiput coriaceous; occipital carina complete.

Mesosoma . Mesoscutum finely coriaceous and densely short-setose; notauli not impressed and weakly indicated by coarser sculpture; mesopleuron smooth and shiny, without precoxal depression; prepectal carina complete though weaker dorsally; (scutellar sulcus hidden by glue); scutellum fine coriaceous, without conspicuous lateral carinae; median area of metanotum with pair of anteriorly converging ridges that fuse to form the mid-anterior metanotal carina; propodeum punctate-rugulose creating pattern of curved lines from mid-longitudinal carina, with strongly crenulated posterior margin and complete mid-longitudinal carina.

Fore wing. Subbasal cell weakly setose basally, with large oval glabrous expansion distally demarked by spurious vein arising from M+CU, with single large brown “D”- shaped sclerome with some ventral setae; vein 1-CU1 approximately 1.25 times length of 2-CU1; vein cu-a swollen and strongly curved; length of veins r: 3-SR: SR1 = 1.0: 1.7: 4.0; vein m-cu approximately 2 times length of 2-SR+M, forming angle of 135 ◦ with 3-CU1; vein 2-M approximately 3 times r-m.

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

Claws. With pecten of four large teeth, the distal-most in the centre of the concavity between the claw proper and basal lobe.

Metasoma. Tergites 1, 2 and basal half of tergite 3 finely longitudinally striate with punctures between the striae; 2nd tergite 1.8 times wider than medially long, 1.25 times longer than 3rd. Male with large glandular pore openings medio-posteriorly on tergites 4–6 and the tergites strongly swollen (bulbous) on either side.

Colouration

Pale yellow except antenna and stemmaticum black. Wings pale brown distally, pale yellow basally, venation yellow except the following in the fore wing which are brown: pterostigma, r, distal part of M+CU, vein 1-CU1, cu-a, most of 1-1A and spurious vein in subbasal cell.

Etymology

Named in reference to the deeply impressed areas surrounding the metasomal gland openings.
