Genus Calosega Terayama, 1999
Calosega Terayama, 1999: 101 .
Type species: Calosega kamiteta Terayama, 1999: 102 .
Diagnosis. Scapal basin shallow and cross-ridged, dorsal margin not carinate; posterior margin of vertex almost straight; occipital carina complete; malar sulcus developed; flagellum compact, intermediate flagellomeres shorter (♀) or at most slightly longer (♂) than wide; pronotum thick, about as long as or slightly longer than mesoscutum along mid-line, with posteromedial and lateral pits; mesoscutum with notauli complete; short track of parapsidal signum present, sometimes indicated as small depression; mesopleuron with omaulus and posterior oblique sulcus (= scrobal sulcus by Kimsey & Bohart (1991)), sometimes weakly differentiated from other surface sculptures; metanotum as long as mesoscutellum; median enclosure of metanotum present, sculptured as mesoscutum; metapectal-propodeal complex with spine-like posterior propodeal projection (female) or posterolateral corner angulate (male); both sexes fully winged; narrow R1 2 v indicated or not differentiated from pterostigma; distal part of pterostigma + R1 2 v 0.8 × 2r-rs 2 v; 2r-rs 2 v almost straight or weakly curving; dark streak of Rs 2 v almost straight or weakly curving; Rs&M 2 v arising at Cu-a 2 v; tarsal claw with submedian tooth; metacoxa with dorsal carina; metasoma sculptured by small and sparsely located punctures .
General characteristics of Calosega are similar to those of Isegama and Cladobethylus Kieffer, 1922 . However, Isegama has a median pronotal groove (not pit-like), and a rounded posterolateral corner of metapectal-propodeal complex (the posteromedian pit is present, and the metapectal-propodeal complex is angulate or spinose in Calosega ); and Cladobethylus has an impunctate welt on vertex (welt absent).
Host. Unknown.
Distribution. Known from Palaearctic Japan (Honshu), Oriental Japan (Ryukyus) ( Terayama, 1999; Terayama & Suda, 2014; Katayama, 2021) and Thailand ( Kimsey, 1995).
Remarks. Two species Calosega kamiteta Terayama, 1999 , C. flavipes ( Kimsey, 1995) are known. Calosega kamiteta was rarely found in temperate area (Honshu, Japan) ( Terayama & Suda, 2014; Katayama, 2021), but the center of abundance of the genus is considered to be in subtropics.
