Taxonomy of Perissosega Krombein (Hymenoptera: Chrysididae, Amiseginae) with description of a new species from Japan Author Mita, Toshiharu text Zootaxa 2022 2022-07-29 5169 3 279 285 journal article 112026 10.11646/zootaxa.5169.3.4 c093e30d-7a06-429f-b33b-1990b004cb07 1175-5326 6952351 D0E5D087-45B1-48DA-901D-033ACB052355 Calosega flavipes ( Kimsey, 1995 ) comb. nov. ( Figs 1–4 ) Perissosega flavipes Kimsey, 1995: 594 . Holotype ♀ ; type locality: Thailand , Khao Yai Natl. Park (CNC). Holotype ♀ , “ THAILAND : 180km N.E. Bangkok , Khao Yai N.P., 780m , 11-18-IV-1990 , M. T ., Moist Semi Evergreen Forest , B. V . Brown ”, “ HOLOTYPE , Perissosega flavipes Kimsey ”, “ HOLOTYPE Perissosega flavipes Kimsey, CNC No. 22205”, “ CNC , 957622” ( CNC , photos examined). Remarks. 2r-rs 2 v is almost straight and the dark streak of Rs 2 v is also almost straight, but the connection is strongly arced ( Fig. 1 ). It appears similar to those of Perissosega and other related genera. However, as indicated by Kimsey (1995) , other important characters do not match the diagnosis of Perissosega ( Krombein, 1983 ; Kimsey & Bohart 1991 ). The absence of a smooth strip on vertex ( Fig. 3 ), the well-developed and not-excavated vertex, the presence of a complete omaulus and posterior oblique sulcus ( Fig. 2 ), and also the presence of a dorsal carina on metacoxa ( Fig. 4 ) are common with Isegama among the genera known in the Indo-China region. However, the presence of postero-medial pit on pronotum and the developed posterior propodeal tooth places this species in the genus Calosega . The general habitus, and the smaller and sparsely located punctures of the body are similar to Calosega kamiteta Terayama, 1999 ; however, C. flavipes is distinguished from C. kamiteta by the wider flagellum, F2 2.0 × wider than long (F2 1.5 × wider than long) and the unique condition of Rs 2 v (Rs 2 v is normal in C. kamiteta , the 2r-rs 2 v and dark streak of Rs 2 v is weakly curving, the connection does not from a strong arc).
