return to key {link to the Hymenoptera Name Server} Type location Zare (Acantholepis nigrisetosa n. sp., Santschi, 1935a: 271; holotype worker only described), from Kasai, Ngombe, 6.xi.1921, by Dr Schouteden; (see Bolton, 1995) .


{Lepisiota nigrisetosa}Santschi's (1935a) description is on {original description}.

Translated this is -
WORKER - TL 3.2 mm; colour black; head, anterior tibiae and peduncle of petiole red brown; mandibles, antenna and tarsi yellow, leg joints yellow to red. Erect pilosity black long and abundant on the gaster and head, less dense on the thorax, absent on the appendages. Legs with a fine pale, translucent pubescence, denser on the antennae. Head dull, finely and superficially reticulate; similar but fainter sculpturation of the pronotum and petiole scale, which are shinier. Mesonotum with irregular longitudinal rugae. Propodeum and metasternum densely reticulo-punctate and matt. Rest of petiole scale, appendages and gaster smooth and shiny.
Head a short oval, about one-seventh longer than wide, rounded behind the eyes. Clypeus convex and with a diffuse medial carina, slightly truncated anteriorly. Mandibles smooth with apices apart when closed, armed with 5 teeth. Postclypeal notch large and long; frontal carinae and parallel longer than their distance apart. Eyes quite large, situated at about the level of the posterior third of the head, and in frontal view not reaching the sides of the face. Scape exceeding the posterior margin of the face. Alitrunk width about three-quarters that of head; pronotum as wide as long; metanotal stomata raised; metanotal groove deep. Dorsum of propodeum raised obliquely to rear, strongly concave between the posterior angles which are in the form of truncated cones. Petiole scale slightly higher than length of posterior peduncle; the summit concave between two fine teeth or spines, these about as long as their basal interval. Gaster large. Legs long.

Related to silvicola Arnold (from Mozambique) but that has a darker head, brown legs, head matt with denser sculpturation, whiter longer finer and more abundant pilosity; the head is longer and ocelli bigger; metanotal groove also even more pronounced but less obliquely raised at rear; petiole scale without teeth.
