Diagnosis. Males: embolus arising prolaterally on tegulum with smooth teeth at base and a lamina widest medially at the end; conductor well developed, hammer-shaped; RTA relatively distant from cymbium ( Figs 80-81View Figures 80-93, 94-96View Figures 94-99). Females: Copulatory openings situated laterally, appearing as large circles (in some cases filled with [mating] plug); epigynal furrows absent; posterior epigynal margin with inconspicuous lobe(s) ( Fig. 82View Figures 80-93). Fertilisation ducts short, situated in the centre of internal duct system, the latter with two blind ending appendages, one long, pointing in a posterior direction, the other short, pointing in an anterior direction, with glandular pores at its tip ( Figs 83-86View Figures 80-93).

Colouration ( Figs 97-99View Figures 94-99). In live specimens, prosoma pale green with olive green margins and fovea. Chelicerae pale yellow, anterior base pale green. Pedipalps and legs pale yellow with light brown markings at the base of the spines. Sternum, gnathocoxae and labium pale yellow. Opisthosoma pale orange, with two large, yellow dots dorsally and two yellow and white stripes laterally. Colour fading in ethanol, leaving a whitish pale appearance; dorsal prosoma with dark marginal band ( Fig. 98View Figures 94-99).

Female (MACN 16835). Total length 10.11. Prosoma: 3.48 long, 3.04 wide. Opisthosoma: 6.63 long, 1.76 wide. Eye diameters and interdistances: AME 0.12, ALE 0.18, PME 0.14, PLE 0.14, AME–AME 0.14, AME–ALE 0.08, PME–PME 0.20, PME–PLE 0.26, AME–PME 0.24, ALE–PLE 0.24.

Chelicerae with 3 anterior and 7 posterior teeth, with ca. 20 denticles in a patch ( Fig. 89View Figures 80-93). Palpal claw with 5-6 teeth ( Fig. 92View Figures 80-93), leg claw with 19-20 teeth ( Fig. 93View Figures 80-93). Median hook of trilobate membrane acuminate and extending beyond lateral projections, may be bent ( Fig. 91View Figures 80-93).

Copulatory organ as in diagnosis. Epigynal field not recognisable. Posterior margin of epigyne with two indistinct lobes.

Colouration as in male, slightly darker.

Variation. Males (n=2): total length 8.61-10.59; prosoma 3.52-3.12; femur I 9.7- 9.05. Females (n=3): total length 10.11-11.74; prosoma 3.48-3.96; femur I 5.98-6.78. Median sac-like parts of the internal duct system may be considerably smaller and not touching each other.

Natural history. One female collected with a spherical egg sac, containing 76 spiderlings. In Costa Rica all specimens were observed on leaves of shrubs and lower tree branches.

Distribution. Ecuador, Eastern Panama and Costa Rica.
