Description
Female: Length of body
12 mm
, of fore wing
10 mm
, of ovipositor
6 mm
.
Antennae with 114 flagellomeres, terminal flagellomere 2.8 times longer than wide, acuminate. Height of clypeus:inter-tentorial distance:tentorio-ocular distance51.0:2.6:2.1. Width of face:width of head:height of eye51.3:1.7:1.0. Height of face:width of face51.0:1.9. Sculpture on face punctate, clypeus rugose. Frons not entirely depressed, only between eyes and toruli. Sculpture smooth, with medial longitudal groove. POL:transverse diameter of posterior ocellus:shortest distance between posterior ocellus and eye51.1:1.0:3.0. Length of eye in dorsal view:distance of occiput and posterior margin of eye52.4:1.0.
Mesosoma approximately 1.6 times longer than maximally deep.
Fore wing: length of veins r:3-SR:SR151.0:2.4:3.0. Length of veins 2-SR:3-SR:rm51.0:2.1:1.1. Length of veins m-cu:2-M51.0:2.6. Length of veins 1-CU1:2- CU151.0:8.1. Shape of vein 1-SR+M straight. Swelling in vein 3-CU1 1.5 times thicker than the other part of the vein.
Legs: Length of fore femur:tibia:tarsus52.3:2.7:1.0. Fore basitarsus 3.5 times longer than deep. Length of hind femur:tibia:tarsus52.3:3.4:1.0. Hind basitarsus 3.2 times longer than deep.
First metasomal tergite 1.1 times longer than wide; median area anteriorly depressed and posterior margin strongly strigated. Second tergite 2.9 times wider than long; triangular median area not raised and whole median and postero-lateral area strigated. Third tergite 3.4 times wider than long; with strigated transverse furrow on anterior margin, raised median area longitudinally strigose to reticulate rugose, sculpture strong. Antero-lateral areas raised and smooth, but narrow. Tergites four and five similar to three. Tergite six strigate, tergites seven and eight smooth.
Orange-brown except for following which are black: antennae, apex of mandibles, varying area around stemmaticum (at least around stemmaticum, sometimes also frons, vertex and occiput black) and ovipositor sheets. Wings fairly evenly weakly darkened, with hyaline zone in fore wing below pterostigma. Apical third of pterostigma darkened. Hind wing evenly darkened.
Notes
The
holotype
of
Goniobracon abdominalis
could not be found and the synomymy is based on the description. A specimen in the BMNH collection is labelled as the type of
Iphiaulax
latiυentris
Cameron, which was described by
Cameron (1906)
. According to
Shenefelt (1978)
, type is lost and it is possible that this is indeed the
holotype
; however, as it bears an accession date of 1914 and is not in the collection of the South African Museum, we are reserving judgement on this and not formally synonymizing this species with
kersteni
.
