Thaumasia argyrotypa Chamberlin & Ivie, 1936: 16   , plate IV, figs. 24, 25, female holotype from Barro Colorado Island   GoogleMaps , Panama [08°59’N, 79°33’W], 30.I-09.II.1928, A. M. Chickering ( MCZ 91344 View Materials ) (examined). New Synonymy

Newly established junior synonyms of Thaumasia heterogyna   . Examination of the types of Thaumasia heterogyna   and Thaumasia argyrotypa   revealed that they belong to the same species, based on the shape of the female genitalia. Since Thaumasia argyrotypa   was described in subsequent pages to Thaumasia heterogyna   , it is synonymized with the later. Both males and females were frequently found together in many scientific collections and also collected together in the field.

Diagnosis. The females of T. heterogyna   resemble those of T. caxiuana   sp. nov. in the general shape of the middle field of the epigynum ( Fig. 92), but can be distinguished by the shallower lateral excavations in the middle field of epigynum ( Figs. 68, 69), by the short head of spermathecae ( Figs 72, 73) The males resemble those of T. scoparia   ( Fig. 145) and T. velox   ( Fig. 57) in the short median apophysis ( Fig. 77), but can be distinguished by the acute and triangular tip of the median apophysis ( Figs 76, 77) and by the flattened and folded tip of the ectal branch of RTA ( Fig. 79).
