33. Deielia phaon (Selys, 1883)

— Deielia phaon brevistigma Oguma, 1915

Deielia phaon brevistigma Oguma, 1915a , p. 50 (Formosa); Oguma, 1922, p. 100, “Formosa”.

Oguma separated the Formosan form as a distinct subspecies from the type form mainly by the smaller body-size. Until a more comprehensive investigation would be made I treat it as D. phaon .

The syntypes of brevistigma are represented by three males and one heterochromatic female: the male bearing the label “Shirin, 31. VII. ” is selected as lectotype.
