Diagnosis

Females of Ogulnius debonaja sp. nov. resemble those of Ogulnius gloriae ( Petrunkevitch, 1930) by the exposed and attached copulatory openings forming a backward-pointed triangle ( Fig. 31C–D View Fig ; Coddington 1986: fig. 124), but O. debonaja can be distinguished by the copulatory ducts convoluted multiple times ( Fig. 31D View Fig ) and by the opisthosoma smooth (i.e., no pattern) ( Fig. 31A–B View Fig ), whereas O. gloriae have the ducts convolute three times ( Coddington 1986: fig. 125) and have dorsal tubercles on the opisthosoma ( Coddington 1986: figs 120–121). Males of O. debonaja can be distinguished from those of O. gloriae by the embolic apophysis prolateral branch encircling the bulb 1.25 times counter-clockwise ( Fig. 30D View Fig ) and a hooked anterior projection of the median apophysis ( Fig. 30F View Fig ), whereas O. gloriae have the prolateral branch smaller, encircling the bulb about 0.75 times counter-clockwise ( Coddington 1986: figs 100–101), and have the projection straight ( Coddington 1986: fig. 99).

Etymology

The specific name is derived from the union of two words, ‘debo’ and ‘nã’ja’, which mean ‘big’ and ‘head’, respectively, in the Naso language, currently spoken by the Naso Tjerdi native people of Panama, and refers to the elevated and bulky cephalic area of the males’ prossoma.

Records and biology

Records are limited to collections made at 895 m a.s.l. and 1135 m a.s.l. in premontane rainforest from Parque Nacional General de División Omar Torrijos Herrera and Reserva Forestal Fortuna, respectively, and 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 at night by looking up, although some specimens were also collected at night by looking down and others during the day by cryptic, beating and looking down.

Variation

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