 Diagnosis. This species is most similar to Ukamenia sapporensis (Matsumura, 1931) but male genitalia of U. thailandica n. sp. differs by a pair of subelliptical pouch on abdominal sternum III (subcircular in U. sapporensis), sacculus projecting lobe shorter than mid length of valva (longer than mid length of valva in U. sapporensis), and subcone-shaped phallus (subcylindrical in U. sapporensis).
