Abstract

The taxonomic composition of Intybia-group species of Thailand and Philippines is revised. The genus Intybia Pascoe, 1886 and the type species I. guttata Pascoe, 1866 are studied and redescribed in detail. Seven species with maculate elytra and sculptured head, T. doipuiensis (Wittmer, 1997), comb. n., T. luzonica (Wittmer, 1997), comb. n., T. mindoroica (Wittmer, 1997), comb. n., T. prudeki (Wittmer, 1997), comb. n., T. thainiensis (Wittmer, 1997), comb. n., T. palawana (Pic, 1910), comb. n. and T. testaceicornis (Pic, 1944) (provisionally) are transferred from Laius Guérin-Méneville, 1831 to Troglointybia Tshernyshev, 2015, and 12 species of Laius Guérin-Méneville with maculate elytra, simple head and lacking tarsal comb in male, I. alboarcuata (Champion, 1921), comb. n., I. balteata (Erichson, 1840), comb. n., I. boettcheri (Wittmer, 1941), comb. n., I. confluens (Wittmer, 1941), comb. n., I. dentatithorax (Pic, 1917), comb. n., I. quadristrigata (Champion, 1921), comb. n., I. subcarinata (Champion, 1921), comb. n., I. subdentata (Champion, 1921), comb. n., I. tetrops (Champion, 1921), comb. n., I. waterstradti (Pic, 1910), comb. n. I. nitidus (Pic, 1948), comb. n. and I. semidepressus (Pic, 1917), comb. n. (the latter two species provisionally) are transferred to Intybia Pascoe. Two species, Intybia korshunovi Tshernyshev, sp. n. from Thailand and I. plonskii Tshernyshev, sp. n. from Philippines are described as new. I. jucunda (Bourgeois, 1891) is recorded for Thailand and Sri-Lanka for the first time. Figures of external appearance, antennae, genitalia, and a distribution map for newly recorded species are provided, and the holotype of I. guttata Pascoe is illustrated.
