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

( Figures 4 , 5 )

Material examined

Holotype. Female, presumed to be from Indonesia, Java, “Ex pupa [sic] Terias ? blanda blanda . Pd. Gedek. XI-[19]36. Coll. Tjoa Tjien Mo; 137; USNM 2054036 ” ( USNM).

Morphology

Length of body 7.8 mm, and of fore wing 7.9 mm.

Head. Antenna with 60 flagellomeres; terminal flagellomere acuminate; head transverse, 1.48 times wider than maximally long in dorsal view; width of head 2.75 times shortest distance between eyes; height of eye 1.67 times shortest distance between eyes; frons smooth and shiny, with weak mid-longitudinal sulcus, without pit in front of anterior ocellus; with sub-carinate ridge along edge next to and almost touching eye; posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 3.0: 1.1; occiput rugulose with curved rugae running from postero-dorsal part of eye; occipital carina ill-defined medio-dorsally where it is confused with fine rugae.

Mesosoma . Mesoscutum coriaceous-rugulose and densely short-setose; posteromedially rugose; notauli hardly defined; mesopleuron smooth and shiny between numerous punctures, without precoxal depression; precoxal suture complete though reduced dorsally; scutellar sulcus with four carinae between the outer ones; (scutellum obliterated by pin); median area of metanotum finely punctured posteriorly;

propodeum with moderately developed postero-lateral, ridge-like projections, rugose and with complete, well-developed mid-longitudinal carina.

Fore wing. Subbasal cell almost entirely glabrous except around margin and at extreme base, with slightly thickened oblique bar arising from vein 1-1A just basal to level of 1-M; vein 1-CU1 1.2 times length of 2-CU1; vein cu-a strongly widened anteriorly tapering towards posterior, nearly straight; length of veins r: 3-SR: SR1 = 1.0: 2.7: 4.9; vein 2-M 2.4 times length of r-m; vein m-cu 1.9 times length of 2-SR+M, forming angle of 135 ◦ with 3-CU1.

Hind wing. Vein M+CU 2.0 times length of vein 1-M; vein 2-SC+R distinctly transverse; basal cell largely setose, subbasal cell largely glabrous (except posteriorly), discal+subdiscal cell with small glabrous area anterobasally near vein cu-a.

Claw. With pecten of three or four large teeth restricted to basal part of basal lobe.

Metasoma. Tergites 1, 2 and basal 0.3 of tergite 3 longitudinally striate with irregular punctures between the striae; 2nd tergite 1.55 times wider than medially long, 1.16 times longer than 3rd.

Colouration

Yellow (including stemmaticum); flagellum, hind tibia and basitarsus black, rest of hind tarsus and other telotarsi brown. Wings hyaline with yellow tinge especially towards base, veins yellow except parastigma and extreme base of pterostigma, and junction of veins 3-CU1, CU1a and CU1b which are black.

Etymology

Named in honour of Charles F. Baker who made a major contribution to the entomology of the Philippines and South East Asia, and who collected many interesting braconids during the early part of the twentieth century.

Notes

The reported host, Terias blanda Boisduval , is now treated as a member of the pierid butterfly genus Eurema . Pieridae are not known hosts of any other members of the subgenus. The collection locality of the holotype is presumed to be the Indonesian island of Java where there is a mountain and a river called Gedek, and where the collector is known to have worked.
