Description
Figs 18, 102–104
Etymology: From Latin porrecta (stretched out, extended or long); refers to the very long embolus and cymbium of the male.
Diagnosis: This species can be recognised by the long, slender embolus that extends retrolaterally along the elongated, slender cymbium (Fig. 103). The palpal tibia has two distinctly separate retrolateral apophyses, of which the dorsal apophysis is larger and more sharply pointed (Fig. 104). Female unknown.

Ocular region reddish brown with black rings around eyes; AER recurved, AME slightly larger than ALE; clypeus height slightly more than AME diameter; AME separated by distance equal to 0.7 their diameter; AME separated from ALE by 0.29 AME diameter; PER procurved, PLE and PME are subequal in size; PME separated by 1.5 PME diameter; PME separated from PLE by slightly less than1.5 PME diameter. Chelicerae brown, slightly darker towards fang base; anterior surface with scattered black setae; three promarginal teeth, median tooth largest, proximal and distal tooth equal in size; two retromarginal tooth, largest situated distally. Sternum brown, border light brown; surface with scattered long setae. Abdomen pale grey; abdomen broader anteriorly, tapering posteriorly; brown scutum extends two thirds dorsum length, dark brown median line extending to half abdomen length; surface smooth with short, fine setae throughout; venter cream. Legs I to IV uniform pale yellow with incomplete band markings; anterior legs more robust than posteriors; legs with dense scopulae ventrally on metatarsi and tarsi; remaining segments covered in scattered setae; leg spines and cusps present. Leg spination: femora: I pl 1, II pl 1, III pl 1, IV pl 1; patellae spineless; tibiae: I plv 7 rlv 2 cusps, II plv 5 rlv 5 cusps, III pl 1 plv 2 rl 1 rlv 2 vt 2, IV pl 2 plv 3 rl 1 rlv 2 vt 1; metatarsi: I plv 15 rlv 9 cusps, II plv 11 rlv 4 vt 2 cusps, III pl 1 plv 2 rl 1 rlv 1, IV pl 2 plv 2 rl 1 rlv 1; tarsi: I plv 6 rlv 3 cusps, II plv 2 rlv 1 cusps (Fig. 112). Palp yellow, elongated slender embolus with narrow point (Fig. 103), curving retrolaterally on narrow, elongated cymbium; two retrolateral tibial apophysis, dorsal apophyses small, rounded, posterior apophyses large sharply pointed (Fig. 104).
