Ephucilla Lelej, 1995 Diagnosis. FEMALE. In the eastern Oriental Region, this genus is recognized by having T6 convex with a quasipygidium that is defined by obscure lateral carinae. Other useful features are mentioned by Lelej (1995b). MALE. See Lelej (1995b). Diversity and Distribution. Fourteen Oriental species are recognized in Ephucilla ( Lelej 2005 ) . Remarks. This genus is easily confused with Sinotilla , because the lateral pygidial carinae are easily overlooked. In fact, two of the species were initially placed in Sinotilla ( Lelej 2005 ) . Structurally, females are similar to Indratilla Lelej, 1993 from Sri Lanka , but that genus always has T1 and T2 each with two apical whitish setal spots.
