Diagnosis. Length: 5–10 mm ; colour: yellow and dark brown or black; head often elongate ( Fig. 7 A); inter– antennal region with medial elevated mound that may be broadly rounded (e.g., Fig. 6 A) to carinate, paired carinae or protuberances not present; frons sometimes with lateral carinae but usually without; notauli present, complete and scrobiculate (e.g., Fig. 3 B); tarsal claws cleft, base pectinate ( Fig. 2 C); mid tibial preapical spines absent; fore tibial spur not elongate (e.g., Fig. 2 F); pair of longitudinal carinae not present on ventral surface of hind trochantellus; fore wing cell 1–RS always present and sessile, vein 2–RS2 either absent or basal sector present; ovipositor long, length exceeding 0.5 metasoma length ( Fig. 9 C). Comments. Cremnops is closely related to Biroia ( Sharkey et al. 2006 ) but can be distinguished from this genus, indeed all agathidine genera, by the presence of comb-like (pectinate) spines on the base of the fore and mid tarsal claws. All Australian species display variations in the yellow and dark brown colour pattern thought to be associated with a putative mimicry complex. Species richness and distribution. Cremnops is well represented in Australia with over 20 species, only four of which are described. The genus appears to be restricted to the northern parts of the continent in the Timorian, Torresian and northern Kosciuskan biogeographic regions.
