Females most resemble B. holguinensis , but are distinguished from the latter and all other species by the following combination of characters: internal genitalia with short bifid spermathecae, with rounded lobes ( Fig. 5E ); legs without a black pattern of coloration ( Fig. 5D ); while female of the latter has their internal genitalia with short rounded spermathecae, without lobes (see Rudolph 1996: fig. 5) and legs with black pattern of coloration ( Fig. 10D ). Males most resembles B. laheredia n. sp. but are distinguished by the combination of the following characters: tibiae I with two ventral spines ( Fig. 7D ); eyes not on prominent mound ( Fig. 7C ) and palpal bulb thin, embolus tip slightly sinuous ( Fig. 8C–E ), whereas B. panamanus tibiae I with 4–5 ventral spines ( Fig. 2D ); eyes on a prominent mound ( Fig. 2C ); palpal bulb globose and embolus tip curved apically ( Fig. 3C–E ).

Femur longer than tibiae, darker than other palpal segments; cymbium with four apical spines ( Fig. 8A, B ); bulb narrow; embolus tip sinuous ( Fig. 8C–E ). Distribution. Veraguas and Panama Oeste Province in Panama . Note. Calatayud-Mascarell et al. (2021) redescribed B. panamanus based on a female from Costa Rica , about 170km away. They present illustrations of three females identified as B. panamanus ( Calatayud-Mascarell et al. 2021 ; fig. 3). One female from Coclé , Panama redrawn from Indicatti 2007, one female from Costa Rica , Limon Province , and the type specimen of the species from Chiriquí , Panama (examined by photo). They also mentioned that B. panamanus could constitute a complex of species rather than a single one. The female and male presented here were collected in Barro Colorado Island, and the female genitalia specifically matches with the female holotype genitalia (see Calatayud-Mascarell et al. 2021 ; fig. 3c). B. panamanus internal genitalia consist of a short spermathecae with rounded lobes, while the other two present rather elongated spermathecae with elongated inner lobes (see Calatayud-Mascarell et al. 2021 ; fig. 3a, b). Consequently, there is a possibility that the specimen presented by Calatayud-Mascarell et al. (2021) represents a new and different species. To be noted that the type locality is situated in the Veraguas province , and not in the Chiriquí province ( Griscom 1924 ).
