Diagnosis

Males and females of Tantra embera gen. et sp. nov. resemble those of Tantra naso gen. et sp. nov. and Tantra kuna gen. et sp. nov. by the wide guanine silver stripe centrally (i.e., above the second pair of opisthosomal apodemes), open posteriorly (Figs 42A–B, 43A–B, 44A–B, 45A–B, 46A–B, 47A–B), but T. embera and T. naso can be distinguished by the dispersed silver guanine blotches anteriorly (Figs 42A– B, 43A–B, 44A–B, 45A–B), whereas T. kuna have two thick silver guanine patches anteriorly, connected to the silver stripe (Figs 46A–B, 47A–B). Females of T. embera can be distinguished by the sternum yellowish-white with olive-green borders and olive-green thick patches anteriorly (Fig. 43C), whereas T. naso have the borders thick (i.e., almost covering all the sternum) and dark olive-green (Fig. 45C). Males of T. embera also resemble those of T. naso and T. kuna by the conductor extension lacking a retrolateral projection, and the conductor apophysis long, exceeding the conductor extension posteriorly (Figs 42D–F, 44D–F, 46D–F), but T. embera and T. naso can be distinguished by the tegular pocket wide and rounded (Figs 42E, 44E), whereas T. kuna have it squared (Fig. 46E). Males of T. embera can be distinguished by the conductor apophysis distally acute, sharpening gradually (Fig. 42E–F), whereas T. naso have the apophysis sharpening abruptly (Fig. 44D, F).

Etymology

The specific name is a noun in apposition to honor the Emberá native people of Panama, which derived from the union of two words, ‘embe’ and ‘ra’, that mean ‘man’ and ‘up’, respectively, in the Emberá language.

Records and biology

Records are limited to collections made at 760 m a.s.l. and 895 m a.s.l. in premontane rainforest from Parque Nacional Altos de Campana and Parque Nacional General de División Omar Torrijos Herrera, respectively (Fig. 1). Males and females have been collected during the day and night mostly by looking down, and less frequently also by beating, looking up and cryptic techniques.

Variation

Some females examined have darker coloration than the described specimens, and some males have the dorsum of the opisthosoma with dispersed silver guanine blotches anteriorly.
