description: Genus Leptopareia Rosa & Xu, gen. nov.
(Figs 1C, 2A, 3A, 7A – 9F, 10A – 11D)
Leptopareia Rosa & Xu, gen. nov. Type species: Hedychrum borneanum Cameron, 1908: 61.
Diagnosis. The genus Leptopareia gen. nov., is closely related to Holophris Mocsáry, but it can be easily separated by the combination of following characteristics: head, in lateral view, with indistinct subgenal area and subgenal carina (Fig. 3A) (distinct in Holophris (Fig. 3B); compare Fig. 65 and Fig. 66b in Kimsey & Bohart 1991); MS short, 0.2–0.5 MOD (longer, 1.0–1.5 MOD in Leptopareia); MS not bisected by genal carina (bisected in Holophris); head elliptical, in frontal view (Figs 8B, 9B, 10B, 11B) (with convex upper profile in Holophris (Figs 4B, 5B, 6B)); inner margin of eye sinuous (straight in Holophris); pronotum laterally with deep fovea (without lateral fovea in Holophris); mesoscutum with distinct and complete notauli (indistinct in Holophris); notaular pits deep and round (usually narrow in Holophris); double omaulus subparallel (triangularly shaped in Holophris); TPC extending to apex of PA (below PA in Holophris); fore wing with elongated C, Sc+R and M, and pterostigma positioned over half length of anterior margin (Fig. 2A) (with shortened C, Sc+R and M, and M considerably arched, pterostigma positioned at less than half length of anterior margin in Holophris); apex of T3 with or without distinct median notch (without distinct median notch in Holophris).
Description. Mandible tridentate; scapal basin deep and usually transversely striated, at least laterally; face with long white setae (up to 1 MOD); head elliptical, in frontal view; gena very narrow under lower margin of eye, not carinate (Fig. 3A); subgenal area indistinct (Fig. 3A); MS <1 MOD and not bisected by genal carina (Fig. 3A); inner margin of eye usually sinuous (Fig. 7B); occipital area, pronotum and mesoscutum medially impunctate or with sparse tiny punctures (Figs 7C, 8C, 9C, 10C, 11C); notauli distinct (Figs 7C, 8C, 9C, 10C, 11C); notaular pits deep and rounded; mesoscutellum usually without anterior foveae (with exception of L. congoensis (Fig. 11C)); mesopleuron sub-rectangular with subparallel double omaulus (Figs 2C, 7A, 8A, 9A, 10A, 11A); TPC extending to apex of PA (Fig. 1C); propodeal angle subparallel and not sharply developed (Fig. 9C); tarsal claw with three to four teeth; apex of T3 with wide semitransparent rim (± 1 MOD), with or without median notch (Figs 7F, 8F, 9F, 10F, 11F).
Biology. Unknown.
Distribution. Leptopareia Rosa & Xu, gen. nov. is currently known from the Afrotropical and Oriental Regions.
Species included. At present, this genus includes seven species: L. borneana (Cameron, 1908), comb. nov., L. luzonensis sp. nov. and L. purpurea (Smith, 1860), comb. nov. (Oriental); L. abyssinica (Mocsáry, 1914), comb. nov. (Figs 10A–10D), L. confusa (Kimsey, 1988), comb. nov., L. congoensis (du Buysson, 1900), comb. nov. (Figs 11A–11D), and L. kalliopsis (Zimmermann, 1961), comb. nov. (Afrotropical).
Etymology. The name Leptopareia is derived from the Greek words λεππτός (leptós = thin) and παρειά (pareia = gena) and refers to the thin and narrow gena with indistinct subgenal area. The gender is feminine.
