Taxonomic position – The new species, Mirax (Centistidea) vertus , is nearest to M. (C.) ubangus sp. n. based on their less broad head in dorsal view (Figs 91, 102) and dark colour of body; they can be distinguished by the following key:

1 Temple in dorsal view somewhat more rounded, ocelli small: OOL 1.5 times as long as POL (Fig. 91). Propodeum with transverse carinula and either polished (Fig. 92) or rugulose (Fig. 98). Pterostigma less narrow, 2.8 times as long as wide, issuing r from its midpoint, r more distinct, 2–SR 1.4 times as long as width of pterostigma, 2–M present (Fig. 94). Lateral margin of sclerotized (brown) plate of first tergite spoon-shape and feebly angled, lateral plate of second tergite partly weakly sclerotized (Fig. 96). Scape and pedicel variably brownish yellow to brown. fm: 1.9–2.1 mm. – Colombia M. (C.) ubangus sp. n.

– Temple in dorsal view somewhat less rounded, ocelli middle-sized, OOL 1.6 times as long as POL (Fig. 102). Propodeum rugulose with distinct carinulate-areolate elements (Fig. 104). Pterostigma narrow: 3.3 times as long as wide, issuing r proximally from its midpoint, r less distinct, 2–SR 1.3 times as long as width of pterostigma, 2–M missing (Fig. 106).

Scape and pedicel dark brown. f: 2.8 mm. – Colombia

M. (C.) vertus sp. n. The new species is also near to M. (C.) adjunctus sp. n. considering their somewhat less broad head in dorsal view (Figs 2, 102), thin hind femur (Figs 4, 7, 105) and dark coloured of body; the distinction between the two species is as follows:

1 Flagellomeres 1–2 equal in length (Fig. 1). Fore wing: pterostigma wide, 2.6 times as long as wide, 2–SR 1.3 times as long as width of pterostigma (Fig. 5). Temple in dorsal view receded, eye in dorsal view not protrud-

Acknowledgements – I am obliged to express my gratitude to Prof. Dr. M. J. Sharkey (Lexington) for his kindness to put me available the Neotropical Mirax material for elabo- ration. A few decades ago the late Dr. C. F. W. Muesebeck (Washington) was kind enough to donate to the Hungarian Natural History Museum (Budapest) several Mirax species taken in some countries of America. My sincere thank should go to the two anonymous referees, they improved considerably the manuscript of the present paper by critical remarks and linguistic corrections.
