The species is dedicated to Joachim Adis ( 1950-2007 ) for his important contributions about the Amazonian forest and its ecology and for his longstanding contribution to the study of arachnids in South America; name in genitive case. Diagnosis . The males of Sparianthina adisi sp. n. are distinguished from those of the remaining species of the genus by the bifid RTA with similar sized branches ( Figs 66-67 ). It resembles Sparianthina deltshevi sp. n. by the long and slender projection at the retrolateral base of the embolus ( Figs 66 , 69 ), but is distinguished from this species by exhibiting a much narrower projection.
