Diagnosis
Urodeta longa Sruoga & Kaila sp. nov. is a small, lightly-coloured species, with indistinct wing markings. It lacks the distinctive black markings that characterize the single other known Oriental Urodeta species, U. noreikai Sruoga & De Prins, which is known from Nepalese Himalayas (Sruoga & De Prins 2013). The female genitalia are highly distinctive with a very large antrum having large internal spines. As such, U. longa Sruoga & Kaila sp. nov. cannot be confused with any other known species of Urodeta.
Etymology
The species name is derived from the Latin ‘ longa ’ (long) in reference to the unusually long papillae anales.

Distribution
So far this species is known only from northern Thailand. We have decided to describe and name it in spite of the paucity of the material. We made this decision as this record considerably extends the known distribution of the genus, filling a large gap between Nepal and Australia that are the closest known occurrences for this genus.
