Figs 1, 40–41

Diagnosis

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

Etymology

The specific name is a noun in apposition to honor the Ngäbe native people of Panama, which derived from the union of two words, ‘ngä’ and ‘be’, that mean ‘person, people’ and ‘born and see, feel or exist’, respectively, in the Ngäbere language.

Description

Male (paratype MACN-Ar 29079)

Total length 1.34. Prosoma: length 0.78, width 0.59, height 0.60. Sternum: length 0.33, width 0.34. Eye diameters and interdistances: AME 0.09, PME 0.08, AME–PME 0.08. Opisthosoma: length 0.96, width 0.83, height 0.70. Leg formula: 1243. Dorsal shield of prosoma white, cephalic area with soft olive-green speckled lines (Fig. 40A–B). Dorsum of the ocular area white (Fig. 40A–B). Sternum yellowish-white with olive-green borders (Fig. 40C). Dorsum of opisthosoma white with two dark olive-green patches posteriorly (Fig. 40A–B). Opisthosoma with two lateral transversal dark olive-green bands (Fig. 40B). Epiandrium, booklung cover, tracheal spiracle, and behind anal tubercle dark olive-green, spinneret field olive-green (Fig. 40C). Femora white but distally olive-green, patella greenish-brown, tibiae, metatarsi and tarsi orange (Fig. 40A–C). Palp: paracymbium hooked, paracymbial process with setae row, tegulum striated with tegular spur wide, rounded, median apophysis elongated with median groove, conductor covering embolic division, conductor posterior extension with small retrolateral projection, conductor apophysis relatively long, embolus laminated, multiple divided embolic apophysis, retrolateral branch filiform, sclerotized, elongated, protruding from beneath conductor (Fig. 40D–F).

Female (paratype MACN-Ar 29077)

Total length 1.86. Prosoma: length 0.77, width 0.65, height 0.60. Sternum: length 0.36, width 0.36. Eye diameters and interdistances: AME 0.08, PME 0.07, AME–PME 0.08.

Epigynal plate whitish-orange (Fig. 41B–C), domed, with dorsal-lateral spurs extending to the midline, dorsal epigynal plate exposed (Fig. 41B–C). Vulva: convoluted copulatory ducts, proximal copulatory ducts with patch of gland ducts dorsally, distal copulatory ducts coiling dorso-ventrally and inserting ventromedially posteriorly into spermathecae, spermathecae round, sclerotized, and connate (i.e., fused along midline), fertilization ducts sclerotized, emerging laterally posteriorly from spermathecae, curving dorsally anteriorly to meet uterus externus (Fig. 41D).

Records and biology

Records are limited to collections made at 1135 m a.s.l. in premontane rainforest from Reserva Forestal Fortuna (Fig. 1). Males and females have been collected during the day by looking down and cryptic technique, and during the night by looking up and looking down.

Variation

Some males examined have the dorsum of the opisthosoma with dispersed silver guanine blotches anteriorly.
