Type material. Holotype male in CAS from Madagascar with label:
MADAGASCAR: Fianarantsoa: Forêt d'Analalava, 29.6 km 280° W Ranohira 22°35'30"S, 45°7'42"E, el 700 m 1–5 ii 2003, dry forest on sandy soil, Fisher, Griswold et al., BLF7390 CASENT 9005863. Paratypes: 8 males and 4 females, same data as holoype. One paratype was used for molecular data by Maddison & Needham (2006; DNA voucher d051).
Etymology. The name refers to the delicate curved tibial apophyses in the male palp, which frame a series of parallel setae, giving the appearance of a harp (Fig. 4).
Diagnosis. Easily distinguished from other Goleba by the distally arising embolus, the long, curved tibial apophyses in the male, and the long copulatory ducts in the female. The form of the embolus and epigynum suggest a relationship to Goleba puella (Simon) (Wanless, 1980) and G. jocquei Szüts. The embolus has only one loop (from distal to proximal and back, in contrast to G. puella, from proximal to distal to proximal to distal), and the epigynal openings are offset anteriorly compared to G. puella. The epigynal openings are smaller and the spermathecae more coiled than in G. j o c q u e i (Szüts, 2001).
Description. Male. Total length 5.3–5.6. Holotype total length 5.4: carapace 2.3 long, 1.7 wide, 1.1 high; abdomen 3.0 long, 1.0 wide. Carapace pale yellow with two yellow brown bands from PLEs to posterior thoracic margin (Fig. 5). Clypeus and lateral margins of carapace with orange scales. Eyes with black surrounds except AMEs. Eye sizes: AME 0.56, ALE 0.23, PME 0.18, PLE 0.20. First eye row 1.06 wide, second eye row 1.25 wide, third eye row 0.83 wide, fourth eye row 0.86 wide, eye area 0.83 long. Clypeus height 0.26. Chelicerae pale yellow, promargin with three teeth, retromargin with three teeth and three denticles. Endites, labium and sternum pale yellow. Sternum with a few hairs. Legs amber, lacking annulations. Spination of leg I: metatarsus v 2­2 ­2, p 1­0­1, r 1­0­1, d 0­1­ 0; tibia v 2­2 ­2, p 1­0­1, r 0­1­1, d 1­1­1; patella p 0­1­0, r 0­1­0; femur p 0­1­1, r 1­1­1, d 1­1­1. Measurements of palp and legs: palp 2.7; leg I 10.0, II 9.7, III 8.9, IV 9.3. Leg formula: 1243. Abdomen long, oval and pale yellow, anterior margin with long brown setae, dorsum with a few orange scales. Palp (Figs. 1–4): Embolus long and thread­like, arising distally on palpal bulb; retrolateral tibial apophysis broad and short, with a row of long setae on dorsal surface; one of the dorsal tibial apophysis long and wide, with distal part strongly curved; the other dorsal apophysis long and thin. The femur of the palp has a subtle protuberance ventrally (Fig. 3).
Female. Total length 6.0–6.4. A female total length 6.0: carapace 2.3 long, 1.9 wide, 1.1 high; abdomen 3.7 long, 2.1 wide. Carapace paler than male, lacking yellow brown bands and marginal orange scales, clypeus with white scales, eye region with white and orange scales. Other characters similar to those of male. Eye sizes: AME 0.53, ALE 0.23, PME 0.17, PLE 0.20. First eye row 1.02 wide, second eye row 1.25 wide, third eye row 0.86 wide, fourth eye row 0.89 wide, eye area 0.79 long. Clypeus height 0.30. Spination of leg I: metatarsi v 2­2 ­2, p 1­0­1, r 1­0­1, d 0­1­0; tibiae v 2­4 ­0, p 1­0­1, r 0­1­1, d 1­1­1; patellae p 0­1­0, r 0­1­0; femora p 0­1­1, r 1­1­1, d 1­1­1. Measurements of legs: I 8.6, II 8.5, III 7.9, IV 9.2. Leg formula: 4123. Epigynum (Figs. 6–7): Openings at lateral sides of median septum. Copulatory ducts long and convoluted with a pair of round sacs near openings. Copulatory ducts exit into an anterior nephroid portion of the spermatheca which proceeds posteriorly to a bulbous portion. No gland­like tubules (Wanless, 1980: 248) were found.
