Machado, Miguel, Viecelli, Rafaela, Guzati, Catherine, Grismado, Cristian J. & Teixeira, Renato A., 2021, Kryptochroma: a new genus of bark-dwelling crab spiders (Araneae, Thomisidae), European Journal of Taxonomy 778, pp. 26-70 : 66

Epicadus stelloides ( Walckenaer, 1837) comb. nov.

Thomisus stelloides Walckenaer, 1837: 514 (female holotype from “Ilê Tortue”, Tortuga, Haiti, deposited in MNHN, probably lost).

Stephanopis trilobata Mello-Leitão, 1929: 56 , fig. 136 (female holotype collected in Goiás, Brazil, deposited in MNHN 21629, examined; female “cotype”, collected in Goiás, Brazil, deposited in MNHN 21628, examined). syn. nov. ( Fig. 27E–F ).

Stephanopis salobrensis Mello-Leitão, 1929: 57 , figs 137–139 (2 females paralectotypes, misidentified; 1 male lectotype designated here, collected from Salobro, Bahia, Brazil, deposited in MNHN 3973, examined). syn. nov. ( Fig. 26 ).

Stephanopis stelloides – Keyserling 1880: 173 (female cotype collected from “Tortosa” by Guérin- Meneville, not located). syn. nov. ( Fig. 27C–D ).

Note

Although the holotype described by Walckenaer (1837) is presumably lost, and the “conspecific” and sympatric specimen used by Keyserling (1880) to describe S. stelloides had not been found, the original descriptions and illustrations ( Fig. 27C–D ) allowed us to unequivocally identify this species as conspecific with Epicadus caudatus ( Fig. 27A–B ), a species that was recently examined and revised by Machado et al. (2015, 2017). Following the priority principle, we transfer Stephanopis stelloides to Epicadus and propose the name E. stelloides comb. nov. as a senior synonym over E. caudatus ( Fig. 27 ). Thus, based on the images provided by Machado et al. (2015), we also recognize the identity of the male specimen of S. salobrensis as conspecific to E. stelloides comb. nov.
