TYPES: Male holotype and female allotype from Foulpointe, Toamasina province, Madagascar, forêt de la lagune, bac jaune, October 1993, Pauly A. (MRAC PBI_OON 9793).

ETYMOLOGY: The species epithet is a name in apposition taken from the type locality.

DIAGNOSIS: Males of O. foulpointe can be easily be distinguished from those of other Opopaea species by a cymbiobulbus longer and slightly wider compared to the patella, with the anterior margin thick, resembling a parrot beak (rising anteriorly before descending abruptly into a steep slope) (figs. 452, 453, 470, 471, 474, 475, 478–486). Females of O. foulpointe can be easily recognized by the very simple epigynum with a slitlike postgynum depression and a very thin scutal ridge, evenly sclerotized, bearing a very small circular parmula in its median (figs. 454, 476, 477).

DESCRIPTION: Male (holotype) (PBI_ OON 9793). Medium-sized species. Total length 1.60. Color: brownish orange. Carapace: pars cephalica slightly elevated posteriorly with one row of two sets of four denticles, three aligned horizontally and the last one placed vertically to the third one (figs. 465, 467). Carapace anterolateral corners without sclerotized triangular extension. Clypeus low, not rebordered. Chilum present, undivided. Cheliceral paturons long, thin, with proximal bosses, directed obliquely, usually detached from the posterior margin

of the clypeus (fig. 465). Eyes medium sized. ALE and PME largest. ALE, PME, and PLE oval; PME darkened compared to other eyes, posterior eye row straight viewed from above, slightly procurved from front; ALE, ALE-PLE, and PLE-PME separated by less than their radius, PME touching throughout most of their length. Sternum longer than wide with radial furrows between coxae, surface smooth, without pits, shape of posterior part between coxae IV constricted then enlarged posteriorly, slightly swollen, especially in males (figs. 468, 469). Area in front of coxae III, each with two lateral lumps, setae abundant, evenly distributed, originating from surface, without hair tufts (figs. 466, 468, 469). Posterior margin of cymbiobulbus with two huge protuberances, both distally and proximally. Fenestra circular, anterior top not sclerotized. Palpal femora almost the same length as palpal patella and inserted at the posterior end of patella (figs. 452, 453, 470, 471, 474, 475, 478–486).

Female (allotype) (PBI_OON 9793). Total length 1.56. Shape of posterior part between coxae IV slightly constricted but not swollen and area in front of coxae III without lumps. Color orange, abdomen oval and not flattened posteriorly. Postgynum depression very short and wide, about one fourth longer to the distance between epigastric furrow and the shallow groove connecting the tracheal spiracles and almost as wide as the distance between the lateral apodemes, ridge weakly sclerotized (figs. 454, 476, 477).

NATURAL HISTORY: O. foulpointe was found near the beach, on red soil, in leaf litter near roads and in gardens.

DISTRIBUTION: O. foulpointe was found along the east coast of Madagascar in the province of Toamasina, and on the nearby island of Mohéli ( Comoros) and on the coast of Kenya, around the town of Kilifi (map 3).
