Isaloides View in CoL F. O. P.- Cambridge, 1900

Isaloides View in CoL F. O. P.- Cambridge, 1900: 163 (Type species: Diaea puta O. Pickard-Cambridge, 1891 designed as Isaloides putus View in CoL by F. O. P.- Cambridge 1900; Holotype female from Bugaba, Panama, deposited in BMNH, examined). Isaloides View in CoL F. O. P.-Cambridge. Banks 1903: 343; Bryant 1940: 408; Jiménez 1992: 53.

Diagnosis. Within Stephanopinae, Isaloides can be recognized by the carapace that is longer than wide and flattened, by the abdomen that is longer than wide and shows four or five pairs of the yellow papules. The male palp has neither retrolateral nor ventral tibial apophyses ( Fig. 10 View FIGURES 6 – 13 , in contrast to Stephanopoides ). Furthermore, in Isaloides the embolus is thin and curly and longer than in Stephanopoides . The epigynum differs from all other Neotropical Stephanopinae by the wide atrium and the small spermathecae ( Figs 11–13 View FIGURES 6 – 13 ; see other details in Jiménez 1992).

Note. The holotype of Isaloides putus was examined to corroborate the transfer of Parastephanops echinatus to this genus. Other specimens of Isaloides were borrowed from AMNH, they belong to different species that should be described in a forthcoming revision of the genus.
