Biroia Szépligeti 1900
Type species: Biroia elegans Szépligeti, 1900 .
Isoptronotum Enderlein, 1920, synonymized by Sharkey et al. (2006). Type species: Isoptronotum taeniocauda Enderlein, 1920 .
Distribution: Old world tropical, including African, Oriental, and Australian regions. Bhat and Gupta (1977) used the name Isoptronotum for the same concept, and it here considered a junior synonym (following Sharkey et al. 2006). Bhat and Gupta (1977) included 10 species (of the present concept of Biroia) in the Oriental Region. No specimens have been recorded from Th ailand but we have collected one or two species; that is, one polymorphic species or two closely related species.
Diversity: 29 species are known of which 12 are recorded from the Oriental region.
Biology: Unknown, the long ovipositors suggest concealed hosts.
Phylogenetic Information. Sister to Zacremnops, a small genus with a Neotropical distribution (Sharkey et al. 2006).
Taxonomic Information. Most authors treated species under Isoptronotum prior to Sharkey et al. (2006).
Diagnosis: Mesoscutum smooth, lacking notauli (Fig.7a); fore and mid claws bifid (Fig. 2a), lateral carina of frons lamellate (high and thin) (Fig. 8a); ovipositor more than half length of metasoma (Fig.20a).
