Kopylov, Dmitry S., Brothers, Denis J. & Rasnitsyn, Alexandr P., 2010, Two new labenopimpline ichneumonids (Hymenoptera: Ichneumonidae) from the Upper Cretaceous of southern Africa, African Invertebrates 51 (2), pp. 423-423 : 427

Rugopimpla botswana sp. n.

Figs 5–7

Etymology: After the country of origin, Botswana; noun in apposition.

Description: Entire body, wing veins and ovipositor very dark; antenna and legs less dark. Antenna filiform, with more than 22 flagellomeres (possibly about 25), basal flagellomeres 3× as long as wide, apical ones 1.5× so. Forewing with 1Rs&1M arched; r–rs nearly straight; 2Rs half as long as 2+3M and twice as long as 4M; r–m as long as 2+3M, with two bullae; 1m –cu 0.67× as long as 2Rs+M; 1m –cu&2Rs+M arched; ramulus twice as long as wide. Hindwing probably with 1Rs 2.5× as long as r–m; 1Cu and cu–a probably subequal in length, junction apparently weakly angled (venation unclear and confused because of superimposition of wings).

Measurements (lengths) in mm:Antenna at least 5.2, head and mesosoma 2.7, metasoma 3.5, ovipositor at least 1.2 (visible free section), forewing 3.9.

Comparison: Differs from R. vulgaris , R. fallax and R. matrona in 1Cu:cu–a and probably 1Rs:r–m ratios in the hindwing; also differs from R. vulgaris in having r–rs nearly straight, and from R. matrona in presence of r–m. Differs from R. angusticella in having areolet wider with 4M longer, and in presence of r–m and ramulus. Differs from R. macra in having 1Rs&1M arched, r–rs nearly straight, and longer ramulus.

Holotype: ♀ BP/2/27390. BOTSWANA: Orapa ; Upper Cretaceous , Turonian. Head and mesosoma considerably damaged, propodeal carinae distinguishable; metasoma well preserved, ovipositor tip lost; antennae nearly complete, legs incomplete; one forewing fairly well preserved, other forewing and hindwings damaged.
