Diagnosis

Males and females of Epeirotypus kra sp. nov. resemble those of E. kote sp. nov. by the whitish-yellow body coloration ( Figs 16A–C View Fig , 17A–C View Fig , 18A–C View Fig , 19A–C View Fig ), but males of E. kra can be distinguished by the median apophysis distal projection relatively acute ( Fig. 16E View Fig ), whereas E. kote have the projection wider ( Fig. 18E View Fig ). Females of E. kra can be distinguished by the vulval bifid sclerotized septum forming a rectangle posteriorly ( Fig. 17D View Fig ), whereas in E. kote the bifid septum resembles an inverted trapezoid ( Fig. 19D View Fig ).

Etymology

The specific name is derived from ‘krä’ which means ‘thin’ in the Ngäbere language, currently spoken by the Ngäbe native people of Panama, and refers to the relatively low prosoma.

Description

Male ( paratype MCZ SFU1N8L020)

Total length 2.21. Prosoma: length 1.25, width 0.98, height 0.71. Sternum: length 0.53, width 0.45. Eye diameters and interdistances: AME 0.11, PME 0.08, AME–PME 0.14. Opisthosoma: length 1.38, width 1.36, height 1.11; with posterior lateral tubercles. Leg formula: 1243. Dorsal shield of prosoma dark olive-green laterally, yellowish-white centrally forming irregular band ( Fig. 16A–B View Fig ). Dorsum of ocular area yellowish-white ( Fig. 16A View Fig ). Thoracic area of prosoma laterally higher ( Fig. 16B View Fig ). Sternum yellow ( Fig. 16C View Fig ). Dorsum of opisthosoma olive-green with five whitish-gray patches, anterior and middle ones fused, covered by sparsely thin olive-green flecks ( Fig. 16A–B View Fig ). Opisthosoma with two lateral posterior tubercles connected ventrally by guanine silver stripe ( Fig. 16C View Fig ). Epiandrium, booklung cover, tracheal spiracle, and spinneret field yellow, olive-green thick patch behind anal tubercle ( Fig. 16C View Fig ). Legs I–II lighter than III–IV, femora and patella yellowish-white, tibiae and metatarsi yellow but distally dark, tarsi yellow ( Fig. 16A–C View Fig ). Palp: paracymbium wider than long, tegulum retrolaterally massive (i.e., almost half the size of bulb), tegular spur rounded, median apophysis rounded, distally notched (see “dorsal notch” in Coddington 1986), with projection extending distally, conductor reduced (i.e., relatively smaller than embolus) partially covering embolus, embolus long, bulky and distally acute ( Fig. 16D–F View Fig ).

Female ( paratypes MCZ SFU2NBD029, MACN-Ar 29220)

Total length 2.95. Prosoma: length 1.42, width 1.06, height 0.72. Sternum: length 0.64, width 0.51. Eye diameters and interdistances: AME 0.11, PME 0.10, AME–PME 0.12. Opisthosoma: length 1.82, width 1.80, height 1.62. Leg formula: 1243. Coloration as in male ( Fig. 17A–C View Fig ). Epigynal plate olive-green ( Fig. 17C View Fig ). Epigynal plate: domed, with transverse groove, central pit deep ( Fig. 17B–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 ( Figs 5D–E View Fig , 17D View Fig ).

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 ). Males and females have been collected mostly at night by looking up; two males and one female were collected during the day by looking down and beating, respectively.
