Type species

Afrocampe prinslooi  gen. et sp. nov., by present designation and monotypy.

Diagnosis

Foretibial spur (calcar) short and evenly acute, tarsi 5-segmented in female ( Fig. 2AView Fig. 2), 4-segmented in male ( Fig. 4DView Fig. 4), antennal funicle 5-segmented in both sexes ( Figs 2BView Fig. 2, 3A, D–EView Fig. 3, 4EView Fig. 4), head lacking facial grooves ( Fig. 2BView Fig. 2) and occipital carina ( Fig. 2DView Fig. 2), mesoscutum with complete notauli ( Fig. 2D, FView Fig. 2), mesoscutellum with two pairs of setae ( Figs 2FView Fig. 2, 3BView Fig. 3), fore wing poorly setose basally, its disc and speculum distinctly delimited, admarginal row of setae distinct and situated on underside of bare area along MV, PMVAbout PMV about 3.0× as long as short STV, with 3 hair rows radiating from it ( Figs 2A, C, EView Fig. 2, 4A, CView Fig. 4); Gt1 not swollen ( Figs 1BView Fig. 1, 2AView Fig. 2, 4AView Fig. 4).

Etymology

The specific epithet is a combination of Afro- (reflecting the Afrotropical distribution of the genus) and - campe (from Tetracampe  ). Gender feminine.

Description

Body with ovoid head ( Fig. 2BView Fig. 2), robust mesosoma ( Fig. 3A, DView Fig. 3) and relatively short metasoma ( Figs 2AView Fig. 2, 4AView Fig. 4); eyes sparsely setose ( Figs 2B, DView Fig. 2, 3EView Fig. 3); flagellum with one anellus (bearing a short seta in the holotype: Fig. 3GView Fig. 3, arrow), 5-segmented funicle and 3-segmented club, apex of which evenly rounded ( Figs 2BView Fig. 2, 3A, EView Fig. 3); face with light sculpture, nearly smooth, with scrobal area sunken into median margined cavity, without facial grooves ( Fig. 2BView Fig. 2); anterior margin of clypeus slightly produced and weakly notched medially ( Fig. 3FView Fig. 3). Occiput not margined, occipital carina missing ( Fig. 2D, FView Fig. 2). Pronotum large, conical, its collum evenly sloping ( Figs 2DView Fig. 2, 3AView Fig. 3). Vertex and pronotum with sparse bristles ( Fig. 2D, FView Fig. 2), midlobe of mesoscutum with distinct straight notauli and three pairs of strong bristles ( Fig. 2DView Fig. 2); mesoscutellum with two pairs of strong bristles, frenal area not distinctly marked off (but somewhat smoother than rest of scutellum in A. prinslooi  gen. et sp. nov., Fig. 2FView Fig. 2). Propodeum relatively transverse, its submedian areas entirely smooth and bare; spiracles small and round, closely adjacent to metanotal margin ( Figs 2FView Fig. 2; 3B–CView Fig. 3). Tarsi of all legs 5-segmented in female ( Figs 2AView Fig. 2, 4AView Fig. 4), 4-segmented in male ( Fig. 4DView Fig. 4). Each leg with one evenly acute spur. Basic part of fore wing poorly setose, with some strong bristles, SMV not broken; with 5 dorsal bristles, wing disc and speculum distinctly delimited by membrane folds and hair rows; admarginal area bare, with a row of setae at underside; PMVAbout PMV long, about 3.0 × as long as short STV, from which 3 hair rows radiate ( Fig. 4CView Fig. 4). Petiole rather transverse ( Fig. 3CView Fig. 3). Metasoma about as long as mesosoma, female gaster ovate ( Figs 2EView Fig. 2, 3B–CView Fig. 3, 4AView Fig. 4); Gt1 not swollen, not more convex than following tergites ( Figs 1BView Fig. 1, 4AView Fig. 4), posterior margins of Gt2–5 straight ( Fig. 3B–CView Fig. 3); syntergum short, with membranous apical tip ( Figs 3CView Fig. 3, 4BView Fig. 4); ovipositor sheaths short, but protruding ( Figs 3CView Fig. 3, 4BView Fig. 4); hypopygium not reaching apex of metasoma, mucro short.

Comparative notes

The new genus is very different from all known chalcidoids, but may be assigned to the subfamily Tetracampinae  of the family Tetracampidae  as judged chiefly from the combination of the 5-segmented tarsi in females, the 4-segmented tarsi of males and the short straight calcar (see Discussion). Afrocampe  gen. nov. has some characters in common with Niticampe Bouček, 1988  : the reduced occipital carina, the missing frontal grooves, the evenly acute calcar, the flat Gt1, the poorly setose base of the fore wing and the distinct forewing speculum. However, Afrocampe  gen. nov. differs from Niticampe  in general habitus, with a large convex mesosoma (slender in Niticampe  ), the 5-segmented antennal funicle (6-segmented in Niticampe  ) and by the setation of the forewing disc (see Discussion).
