Anuvinda Lehtinen 1967

Anuvinda Lehtinen, 1967: 214 , fig. 441. Type-species by monotypy and original designation: Titanoeca escheri Reimoser, 1934: 436 , fig. 7; Lehtinen, 1967; Platnick, 2009.

Diagnosis. The males of the genus Anuvinda are distinguished from those of the genus Pandava , Nurscia and Titanoeca by the presence of a patellar apophysis ( Fig. 1, 2, 5 ) and from those of the genus Goeldia by the presence of a grooved prolateral lobe (PLT), facing the retrolateral lobe in the tibial apophysis RLT (see Lehtinen 1967: 459, fig. 426, 427 and Leech 1972, fig. 185, 187, 189 and 191 for comparison). The tegular process is short and prolaterally curved and the apex of the median lobe (MLT) is hyaline and tripartite. The females are distinguished from those of the genera Goeldia , Nurscia , Pandava and Titanoeca by the inverted T shape of the median field, with two atria ( Fig. 6 ), the sinuous copulatory ducts and the spermathecae oval and vertically elongate ( Fig. 7 ).
