Diagnosis

Males and females of Tantra bribri gen. et sp. nov. resemble those of Tantra ngabe gen. et sp. nov. by the white general coloration ( Figs 38A–C View Fig , 39A–C View Fig , 40A–C View Fig , 41A–C View Fig ), but T. bribri can be distinguished by the six olive-green patches on the dorsum of the opisthosoma ( Figs 38A View Fig , 39A View Fig ), whereas T. ngabe have two olive-green patches ( Figs 40A View Fig , 41A View Fig ). Males of T. bribri also resemble those of T. ngabe by the tegular pocket wide and rounded ( Figs 38E View Fig , 40E View Fig ), but T. bribri can be distinguished by the pocket posterior side smooth (i.e., not projecting; Fig. 38D View Fig ), whereas T. ngabe have it pointed ( Fig. 40D View Fig ).

Etymology

The specific name is a noun in apposition to honors the Bribri native people of Panama, which derived from ‘bri-bri’ that literally means ‘hard-hard’ (= strong) in the Naso language, currently spoken by the Naso Tjerdi native people of Panama, but it can also be interpreted as ‘brave’.

Records and biology

Records are limited to collections made at 895 m a.s.l. in premontane rainforest from Parque Nacional General de División Omar Torrijos Herrera ( Fig. 1 View Fig ). Males and females have been collected mostly during the night by looking down and looking up, although males and females were also collected during the day by cryptic technique.

Variation

Some males and females examined have lighter coloration than the described specimens.
