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. 2A View Figure ), 4-segmented in male ( Fig. 4D View Figure ), antennal funicle 5-segmented in both sexes ( Figs 2B View Figure , 3A, D–E View Figure , 4E View Figure ), head lacking facial grooves ( Fig. 2B View Figure ) and occipital carina ( Fig. 2D View Figure ), mesoscutum with complete notauli ( Fig. 2D, F View Figure ), mesoscutellum with two pairs of setae ( Figs 2F View Figure , 3B View Figure ), 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, E View Figure , 4A, C View Figure ); Gt1 not swollen ( Figs 1B View Figure , 2A View Figure , 4A View Figure ).

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. 2B View Figure ), robust mesosoma ( Fig. 3A, D View Figure ) and relatively short metasoma ( Figs 2A View Figure , 4A View Figure ); eyes sparsely setose ( Figs 2B, D View Figure , 3E View Figure ); flagellum with one anellus (bearing a short seta in the holotype: Fig. 3G View Figure , arrow), 5-segmented funicle and 3-segmented club, apex of which evenly rounded ( Figs 2B View Figure , 3A, E View Figure ); face with light sculpture, nearly smooth, with scrobal area sunken into median margined cavity, without facial grooves ( Fig. 2B View Figure ); anterior margin of clypeus slightly produced and weakly notched medially ( Fig. 3F View Figure ). Occiput not margined, occipital carina missing ( Fig. 2D, F View Figure ). Pronotum large, conical, its collum evenly sloping ( Figs 2D View Figure , 3A View Figure ). Vertex and pronotum with sparse bristles ( Fig. 2D, F View Figure ), midlobe of mesoscutum with distinct straight notauli and three pairs of strong bristles ( Fig. 2D View Figure ); 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. 2F View Figure ). Propodeum relatively transverse, its submedian areas entirely smooth and bare; spiracles small and round, closely adjacent to metanotal margin ( Figs 2F View Figure ; 3B–C View Figure ). Tarsi of all legs 5-segmented in female ( Figs 2A View Figure , 4A View Figure ), 4-segmented in male ( Fig. 4D View Figure ). 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. 4C View Figure ). Petiole rather transverse ( Fig. 3C View Figure ). Metasoma about as long as mesosoma, female gaster ovate ( Figs 2E View Figure , 3B–C View Figure , 4A View Figure ); Gt1 not swollen, not more convex than following tergites ( Figs 1B View Figure , 4A View Figure ), posterior margins of Gt2–5 straight ( Fig. 3B–C View Figure ); syntergum short, with membranous apical tip ( Figs 3C View Figure , 4B View Figure ); ovipositor sheaths short, but protruding ( Figs 3C View Figure , 4B View Figure ); 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).
