A new species of the genus Sulawesifulvius, S. thailandicus Wolski, Yasunaga & Gorczyca, sp. n., is described from Thailand. The present finding also represents the first distribution record in Indochina for the genus. Color adult habitus images for S. thailandicus and S. schuhi (type species of the genus), male genital drawings of S. thailandicus, and scanning electron micrographs of selected structures of S. schuhi and S. thailandicus are provided.

Sulawesifulvius Gorczyca, Chérot & Štys, 2004 is a unique cylapine genus established by
In this paper, a new species, S. thailandicus, is diagnosed and described based on material recently collected in central Thailand. Habitus photographic images of Sulawesifulvius schuhi (type species of the genus) and S. thailandicus sp. n., male genitalic drawings of S. thailandicus sp. n., and scanning electron micrographs of the selected structures of S. schuhi and S. thailandicus are provided. The present discovery of a new species in Thailand also represents the first distributional record from Indochina for the genus.
Observations were made using an Olympus SZX12 stereomicroscope and an Olympus BX50 optical microscope. Digital images of live individuals were taken by TY with Canon EOS Kiss digital camera body + Olympus OM-System. Scanning electron micrographs were taken using Hitachi S-3400N and Phenom XL Scanning Electron Microscopes. Measurements were taken using an eyepiece (ocular) micrometer; all measurements are given in millimeters.
Dissections of male genitalia were performed using the technique mentioned by
Recognized by the following set of characters: dorsum yellow with large dark brown and red areas (Figs

Sulawesifulvius thailandicus is most similar to S. schuhi and S. yinggelingensis in having large red markings on the dorsal surface (Figs

Female. Similar to male in coloration, structure, texture, and vestiture.
Unknown.
The specific name refers to the country where the holotype was collected.
Holotype male. Nakhon Ratchasima Prov., Wang Nam Khieo, Sakaerat Environmental Research Station, Sakaerat Biosphere Reserve, 14°30'27"N, 101°55'39"E, 410 m alt., light trap, 25 Sep 2013, T. Yasunaga (
Similar, shagreened surface of the dorsum to that found in Sulawesifulvius is present in many genera of Fulviini (
The subdivision of the labial segment II in the Fulviini was noted among others by
In Sulawesifulvius the dorsal wall of the genital capsule is long, weakly shorter than ventral wall and the genital opening is terminal in orientation (Fig.
