description: Austroterobia noyesi sp. nov.   
(Figs 40–50)  
 Diagnosis. Both sexes: head and mesosoma brown, without metallic reflections (Figs 40–42); gena not depressed at mouth corner (Fig. 46); POL 0.5–0.7× OOL; mandibular formula 3:3; pronotum not visible in dorsal view (Fig. 48); notauli visible throughout length of mesoscutum (Fig. 48); prepectus and dorsal side of propodeum bare (Fig. 49); axillae wide apart (Fig. 48); posterior margin of mesoscutellum not densely setose, without distinct spine, although acutely pointed (Fig. 48); anterior margin of propodeum not distinctly raised, not concealing dorsellum (Fig. 50); propodeal plicae present, diverging posteriorly (Fig. 50).   
 This is the second described species of Austroterobia having the mandibular formula 3:3, after A. iceryae. Both occur in Africa, but apart from the mandible structure, the two species are very distinct.

 Description. Female. Body length: 1.1–1.7 mm.   
 Colour. Head and mesosoma from light to dark reddish-brown, gaster lighter (Figs 40, 41). Eyes and ocelli whitish (Fig. 44). Antenna (Fig. 46) with scape and pedicel yellowish-brown; flagellum dark brown. Mandibles yellowish. Legs (Fig. 40) with coxae, trochanters and femora from paler to darker brown, tibiae and tarsi yellowish. Fore wings with disc slightly infumate (Fig. 47); hind wings hyaline (Fig. 41). Tegula and venation reddish-brown (Fig. 47). Body setation pale brown, wing setation brown (Figs 43, 47, 48).   
 Sculpture. Head coriaceous to alutaceous except for smooth clypeus and genae (Figs 43, 44, 46); mesoscutum very shallowly reticulate, axillae and mesoscutellum rugose (Fig. 48); median area of propodeum, except plicae and median carina, almost smooth (Fig. 50); mesopleuron mostly smooth, with shallow coriaceous to finely reticulate femoral depression, without central pit (Fig. 49); prepectus and metapleuron smooth (Fig. 49); gaster smooth.   
 Structure. Head. Toruli very high, much closer to median ocellus than to ventral margin of clypeus (Fig. 43). Scape surpassing level of vertex (Fig. 46); flagellum apparently with only two anelli, the first one extremely short (Fig. 46). Gena not depressed at mouth corner (Fig. 46), posterior margin finely carinate. Malar sulcus present (Fig. 46). Eyes virtually round (Fig. 46), inner margins not sinuate in middle and almost parallel in lower part (Fig. 43). Funicular segments not pedicellate (Fig. 46). Head width 2.7–3.0× length (66:22) in dorsal view and 1.4× height (66:47) in frontal view. POL about 0.7× OOL (10:15). Eye height about equal to length (20:20), 0.9–1.1× malar space (20:22), and subequal to scape length (20:19). Head width about 1.2× length of pedicel plus flagellum (66:56). F1 width about 1.2× length (7:6); F5 width 1.2× length (6:5); clava length about 2.6× width (17.0:6.5).   
Mesosoma. Dorsally setose, except for metanotum and median area of propodeum (Fig. 48); prepectus and metapleuron bare (Fig. 49); mesopleuron bare except for a few setae on lower mesepisternum (Fig. 49). Pronotum not visible in dorsal view (Fig. 48). Notauli complete (Fig. 48). Axillae wide apart, medially connected by wide groove separating mesoscutum from mesoscutellum (Fig. 48). Posterior margin of mesoscutellum acute medially, but without distinct spine (Fig. 48). Anterior margin of propodeum not distinctly raised, not concealing dorsellum (Fig. 50). Propodeum with distinct median carina, and posteriorly diverging and almost complete plicae (Fig. 50); with wide depression margined by incomplete sinuous carina laterad to each plica, towards spiracle (Fig. 50). Fore wing (Fig. 47) completely setose, without speculum; parastigma without hyaline break; marginal vein slightly thickened. Mesosoma length about 1.2× width (65:56), width about 1.4× height (65:45). Mesoscutum width about 2.2× length (56:25). Mesoscutellum length about 0.9× width (27:31). Propodeum length about 0.4× mesoscutellum length (12:27). Fore wing length about 2.1× width (150:70); MV 1.0–1.2× SV (25:25); PV 1.8× MV (45:25).  
Gaster. Broadly ovate, from about equal to slightly shorter than head plus mesosoma (Figs 40, 41); length 1.5–1.8× width (83:55).  
 Male. Differs from the female mainly as follows. Body length: 1.2–1.7 mm. Lower face more swollen, almost entirely smooth (Fig. 45). Genae larger, hence head appearing less triangular in frontal view (Fig. 45). Eyes smaller, hence malar space as well as temples in dorsal view of the head longer. Scape shorter, not surpassing level of vertex, with ventral protuberance towards apex (Figs 42, 45); anelli (especially the second) and proximal funicular segments (F1–F2) longer, much longer than broad and thinner than rest of segments (Fig. 45). Head width about 2.5× length in dorsal view and width about 1.3× height in frontal view. POL 0.5–0.7× OOL. Eye height about 1.1× length and about 0.8× malar space. F1 length 1.8–2.0× width; F5 quadrate; clava length 2.4–3.1× width (in allotype clava collapsed). Mesosoma length about 1.1× width, width about 1.3× height. Mesoscutum width about 2.3× length. Mesoscutellum length about 0.8× width. Fore wing length about twice width; MV about 1.2× SV; PV about 1.6× MV. Gaster from about as long as head plus mesosoma to shorter than mesosoma, usually strongly collapsed dorsally or laterally, length about 2.2× width (Fig. 42).   
 Distribution. Democratic Republic of Congo, Ivory Coast, Nigeria, Togo.   
 Biology. Unknown.   
 Remarks. The female specimen from CNC was identified by Z. Bouček in 1989 as A. iceryae (see material examined). However, this specimen clearly differs from the type material of A. iceryae (formally described 15 years later). The new species seems the most sexually dimorphic species of Austroterobiinae known so far (see male characters above).   
 Etymology. Named in honour of Dr. John Noyes (BMNH), founder of the Universal Chalcidoidea Database, for his contribution to the systematics of Chalcidoidea.
