Genus Changiola Gorochov, 2004

Type species: Changiola subita Gorochov, 2004 ; by original designation

Diagnosis (from Gorochov, 2004, Gorochov & Tan, 2012). The genus is similar in size, habitus and tegmen as Kerinciola , Singapuriola , Tembelingiola and Tramlapiola . Male subgenital plate is similar to that of Tramlapiola and Tembelingiola , but posterior margin with a median notch. Male genitalia distinctly differs by: epiphallus complete, with a H-shaped distal part and S-shaped proximal parts; rachis (= guiding rod) moderately long, without upper process; endoparameres moderately long, curved, not connected with formula (= mold of spermatophore) attachment plate; ectoparameres and additional plate-like sclerites developed (absent in all Pteroplistinae genera). Ovipositor short.

Biogeography notes ( Fig. 1 ). The genus currently comprises of three species, two from Malay Peninsula and one from Indochina ( Thailand). The two species from Malaysia [ Changiola perakensis ( Chopard, 1969) and Changiola pahangi Gorochov, 2011 ] are found in lower montane forests whereas Changiola subita Gorochov, 2004 from Thailand is found in lower coastal mountains. We describe a new species from Borneo, the first for the genus.
