Benjamin, Suresh P., 2014, Two new species of Pharta Thorell, 1891 with the description of Ibana senagang gen. et sp. nov. (Araneae: Thomisidae), Zootaxa 3894 (1), pp. 177-182 : 180-181

Ibana gen. n.

Type species: Ibana senagang sp. nov.

Etymology. Named for the Iban people of Borneo. It is considered feminine in gender.

Diagnosis. Males of Ibana senagang gen. nov., sp. nov. can be distinguished from males of other Stephanopinae by the following combination of characters: presences of a smaller conductor (less than half the size of the cymbium), presence of a sperm duct inward turn, hook-shaped tibial apophysis, palpal tibia furnished with at least 3 thick long spines, lack of trichobothria on the dorsal surface of the cymbium. Females of the new genus can be distinguished by the presences of kidney shaped spermathecae and longer copulatory ducts, lack of an epigynal lip and epigynal teeth.

Further, the new genus is most closely related to and likely to be confused with Cebrenninus Simon, 1887 , Epidius Thorell, 1877 and Pharta , known from the Oriental region. It can be separated from these genera in addition to the characters given above, as follows: from Cebrenninus by the longer copulatory ducts and lack of an extra tegular process; from Epidius - by the absence of an elongated male palp tibia (tibia is longer than the cymbium in Epidius ); from Pharta - by absence of a macro-trichobothrium on the palpal tibia, absence of serrated tarsal setae, absences of posterior epigynal pockets and oval, dual-chambered spermatheca.
