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).
