Thaumasia heterogyna Chamberlin & Ivie, 1936: 15, plate IV, fig. 26, female holotypefrom Barro Colorado Island, Panama[ 08°59’N, 79°33’W], 30.I-09.II.1928, A. M. Chickering(MCZ 91345) (examined). Thaumasia argyrotypa Chamberlin & Ivie, 1936: 16, plate IV, figs. 24, 25, female holotypefrom Barro Colorado Island, Panama[ 08°59’N, 79°33’W], 30.I-09.II.1928, A. M. Chickering(MCZ 91344) (examined). New Synonymy Newly established junior synonyms of Thaumasia heterogyna.Examination of the typesof Thaumasia heterogynaand Thaumasia argyrotyparevealed that they belong to the same species, based on the shape of the female genitalia. Since Thaumasia argyrotypawas 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. heterogynaresemble 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).
