description: Rugosothynnus neocorrugatus sp. nov.
(Fig. 28, 37–38)
Diagnosis. Male. Clypeus with inverted polished cordate area; S1 sharply medially raised but not sagittally carinate; S2 not tuberculate; and cuspis truncate, distoventrally produced and hook-like in profile.
Description. Male. Head. Rounded, not emarginate posteriorly, not narrowed behind eyes; clypeus truncate, weakly convex, with inverted Y-shaped carina, branches curved to form polished, impunctate, cordate area, closely punctate laterally; antennal prominence with obscure V-shaped carina, produced below carina to antennal insertions; frons obscurely transversely carinate, rugosely punctate, obscurely sagittally carinate, not depressed; vertex closely punctate, impunctate posterolaterally to hind ocelli; gena closely punctate.
Mesosoma. Pronotum narrower than head, closely punctate to rugosely punctate, anterior margin emarginate, raised, carinate, acutely produced laterally; mesoscutum rugosely punctate; tegulae punctate; mesoscutellum closely punctate, weakly convex, subtriangular, truncate posteriorly; metanotum closely punctate, below level of mesoscutellum; propodeum oblique posteriorly, not transversely carinate, finely transversely rugosely punctate; fore coxae punctate; mesopleura closely to rugosely punctate.
Metasoma. T1–6 closely punctate, T1–5 sparsely punctate posteriorly; S1 rugosely punctate, S2–7 closely punctate; gradulus straight and scrobiculate on T2–5 and S3–5, straight and weakly scrobiculate on T6 and S6, obscure on S7; T1 truncate anteriorly, subtuberculate above truncation; S1 sharply medially raised but not sagittally carinate; S2 not tuberculate; hypopygium without basal angles; cuspis truncate, distoventrally produced and hooklike in profile; paracuspis of medium length.
Colour. Black; ocellar macula orange; wings weakly infuscate.
Length. Body 17 mm; fore wing 12 mm; hind wing 9 mm.
Female. Unknown.
Distribution. Inland Queensland, Carnarvon National Park.
Etymology. The specific name is derived from Greek and refers to the similarity of this species to R. corrugatus.
Remarks. The polished cordate area on the clypeus uniquely distinguishes this species.
This species differs from R. corrugatus by: punctation closer and deeper, closely punctate to rugose-punctate on head, mesosoma and S1; S1 sharply medially raised; pronotum with anterior margin acutely produced laterally; mesoscutellum weakly convex; propodeum oblique posteriorly; T1 obliquely truncate anteriorly; S2 not tuberculate; paracuspis of medium length; and wings weakly infuscate. R. houstoni sp. nov. has the punctation on the head and mesosoma larger and deeper.
Material examined. Queensland: Holotype ♂ Carnarvon National Park, 8–10.xii.1979, M.A. Schneider and G. Daniels, (UQIC).
