Diagnosis

Females of Epeirotypus drune sp. nov. resemble those of E. bule sp. nov. by the body coloration overall dark gray ( Figs 21A–C View Fig , 22A–C View Fig ), but E. drune can be distinguished by the opisthosoma with three pairs of dorsal whitish-gray patches covered by sparsely thick dark gray flecks ( Fig. 21A View Fig ) and the vulval bifid sclerotized septum forming a wide, rounded, posterior curve ( Fig. 21D View Fig ), whereas E. bule have the opisthosoma with whitish-gray patches forming a ‘happy face’ in dorsal view ( Fig. 22A View Fig ) and have the bifid septum narrow ( Fig. 22D View Fig ).

Etymology

The specific name is derived from ‘drune’ which means ‘black’ in the Ngäbere language, currently spoken by the Ngäbe native people of Panama, and refers to the dark general coloration.

Description

Female ( paratype MACN-Ar 29084)

Total length 3.24. Prosoma: length 1.43, width 1.12, height 0.82. Sternum: length 0.70, width 0.55. Eye diameters and interdistances: AME 0.14, PME 0.14, AME–PME 0.15. Opisthosoma: length 2.28, wide 2.47, high 2.10; with posterior lateral tubercles. Leg formula: 1243. Dorsal shield of prosoma dark laterally, yellowish-white centrally ( Fig. 21A View Fig ). Dorsum of ocular area dark ( Fig. 21A–B View Fig ). Thoracic area of prosoma laterally higher ( Fig. 21B View Fig ). Sternum yellowish-orange with dark borders ( Fig. 21C View Fig ). Opisthosoma color overall dark gray with three pairs of dorsal whitish-gray patches laterally covered by sparsely thick dark gray flecks ( Fig. 21A–B View Fig ). Opisthosoma with two lateral posterior tubercles connected ventrally by guanine silver stripe ( Fig. 21C View Fig ). Epigynal plate, booklung cover, tracheal spiracle, spinneret field and behind anal tubercle dark gray, surrounded by whitish-gray area ( Fig. 21C 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. 21A–C View Fig ). Epigynal plate: domed, with transverse groove, central pit deep ( Fig. 21B–C View Fig ). Vulva: copulatory ducts massive, proximally with patch of gland ducts dorsally, 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. 21D View Fig ).

Male

Unknown.

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 ). Females have been collected mostly at night by looking up, although a specimen was collected during the day by cryptic technique.

Variation

Some females examined have the prosoma and opisthosoma completely dark.
