Diagnosis

Females of Epeirotypus tain sp. nov. can be distinguished from those of other species of Epeirotypus by the opisthosoma coloration overall reddish-brown with a white transversal central stripe ( Fig. 23A View Fig ).

Etymology

The specific name is derived from ‘tain’ which means ‘red’ in the Ngäbere language, currently spoken by the Ngäbe native people of Panama, in reference to the overall reddish-brown coloration.

Female ( holotype MIUP SFU2NBH025)

Total length 2.66. Prosoma: length 1.20, width 0.92, height 0.72. Sternum: length 0.54, width 0.47. Eye diameters and interdistances: AME 0.12, PME 0.12, AME–PME 0.13. Opisthosoma: length 1.81, width 2.09, height 1.74; with posterior lateral tubercles. Leg formula: 1243. Dorsal shield of prosoma dark, fovea brownish-orange ( Fig. 23A–B View Fig ). Dorsum of ocular area dark ( Fig. 23A View Fig ). Thoracic area of prosoma laterally higher ( Fig. 23B View Fig ). Sternum brownish-orange with reddish-brown borders ( Fig. 23C View Fig ). Opisthosoma color overall reddish-brown with three pairs of dorsal whitish-gray patches laterally, middle ones fused forming transversal central stripe ( Fig. 23A–B View Fig ), covered by sparsely thick dark flecks ( Fig. 23C View Fig ). Opisthosoma with two lateral posterior tubercles ( Fig. 23C View Fig ). Epigynal plate, tracheal spiracle and behind anal tubercle reddish-brown, covered by sparsely thin whitish-gray flecks; booklung cover whitish-gray, spinneret field orange ( Fig. 23C View Fig ). Legs I–II darker than III–IV, femora and patella greenish-brown, tibiae and metatarsi brownish-orange but distally dark, tarsi brownish-orange ( Fig. 23A–C View Fig ). Epigynal plate: domed, with transverse groove, central pit deep ( Fig. 23C View Fig ). Vulva: copulatory ducts massive proximally, with patch of gland ducts dorsally, and heavily sclerotized distally inserting dorsolaterally posteriorly into spermathecae, spermathecae anteriorly sharp, sclerotized, and connate (i.e., fused one above the other), fertilization ducts sclerotized, relative small, emerging dorsally posteriorly from spermathecae, curving anteriorly to meet uterus externus ( Fig. 23D View Fig ).

Male

Unknown.

Records and biology

Records are limited to collections made at 1135 m a.s.l. in premontane rainforest from Reserva Forestal Fortuna ( Fig. 1 View Fig ). The only female has been collected at night by looking up.

Remarks

Females of E. tain sp. nov. resemble those of E. bule sp. nov. by the vulval bifid sclerotized septum forming a narrow, rounded, posterior curve ( Figs 22D View Fig , 23D View Fig ).
