TYPES: Male holotype from Antananarivo: 3 km 41 ° NE Andranomay, 11.5 km 147 ° SSE Anjozorobe, 18 ° 289240S, 47 ° 579360E, 1300 m, pitfall traps, montane rainforest, 05–13 December 2000, Fisher-Griswold Arthropod Team (CASC PBI_OON 34422). Female allotype from Toamasina: Ambatovy, 12.4 km NE Moramanga, 18 ° 509220S, 48 ° 189300E, 1080 m, pitfall trap, 4–7 March 2007, B.L. Fisher (CASC PBI_OON 3843).

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

DIAGNOSIS: Males of andranomay resemble those of O. foulpointe in having small eyes and very long and thin legs (figs. 141–142 [ andranomay ], 458–459 [ foulpointe ]), and O. manongarivo , and O. sandranantitra , by having a cymbiobulbus almost the same length as the patella (figs. 151–152, 629– 630, 731–732), but can be distinguished from other Opopaea species by the fenestra anterior top raised into a sclerotized dome, which abruptly and steeply slopes toward the tip (figs. 151–152, 155–156, 165–166). Females of andranomay can be easily recognized by a thick scutal ridge with a thick boatlike sclerotized median area bearing a small elliptical parmula (figs. 137, 157–158).

DESCRIPTION: Male (holotype) (PBI_OON 34422). Medium-sized to large species. Total length 1.71. Color: brown orange (figs. 141– 144). Carapace: pars cephalica elevated posteriorly with one continuous row of four recurved denticles (figs. 148, 149). Carapace anterolateral corners without sclerotized triangular extension. Clypeus low, not rebordered. Chilum absent. Cheliceral paturon long and thin distally but heavier and bearing lateral boss proximally, usually detached from clypeus posterior margin and directed obliquely (figs. 147, 148). Eyes small. ALE largest. ALE oval, PME oval, PLE circular; PME darkened compared to other eyes; posterior eye row straight viewed from above, slightly procurved from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide, with radial furrows between coxae; surface smooth, without pits, shape of posterior part between coxae IV hexagonal, not constricted. Lateral margins of area between coxae III unmodified, without lumps; setae abundant and evenly distributed, originating from surface, without hair tufts (fig. 150). Cymbiobulbus with a short sclerotized tip, and three protuberances: two on posterior margin (one small, distal and the other large, proximal) and one on retrolateral margin (figs. 152, 156). Palpal femora half the size of palpal patella and inserted almost medially to it. Fenestra large and located at the anterior part of the cymbiobulbus at one third of its length (figs. 135–136, 151– 152, 155–156, 159–166).

Female (allotype) (PBI_OON 3843). Total length 1.91. Brown orange. Abdomen elongated, oval, and not flattened laterally

toward posterior end (figs. 138–140). Epigynum postgynum depression short and narrow, with a thin and weakly sclerotized ridge (figs. 137, 157–158).

NATURAL HISTORY: O. andranomay was mostly found in montane rainforest at high elevation (above 1000 m).

DISTRIBUTION: Mostly found along the central and eastern coast of Madagascar in the provinces of Antananarivo and Toamasina (Andranomay, Ambatovy) (map 1).
