Diagnosis

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

Etymology

The specific name is a noun in apposition to honor the Naso native people of Panama, which derived from the union of two words, ‘na’ and ‘so’, that mean ‘life or water’ and ‘to be or to believe’, respectively, in the Naso Tjerdi language.

Records and biology

Records are limited to collections made at 2299 m a.s.l. in lower montane rainforest from Parque Internacional La Amistad ( Fig. 1 View Fig ). Males and females have been collected mostly during the night by looking down and looking up, and less frequently also by beating and cryptic techniques.

Variation

Some females examined have a lighter coloration than the described specimens.
