ETYMOLOGY: The species is named after the
type
locality.
DIAGNOSIS: The male differs from others in the group by the large bulb-cymbium (about 0.7 patella-tibia length; but about
0.5 in
other species) and the presence of a shallow dorsal groove proximally on the bulb (fig. 482). The female differs in having a smaller dorsal scute (fig. 279) and the epigynal region weakly sclerotized and the receptaculum short and relatively straight (W/L about 0.25) (figs. 296, 297).
MALE (PBI_OON 03234). Total length 1.53, carapace length 0.74, width 0.62. CEPHALOTHORAX: Carapace (figs. 269, 270, 274) as in
M. ranomafana
. Eyes as in
M. ranomafana
, but slightly smaller; eye area about 0.5 carapace width, length subequal to clypeus length (figs. 269, 273). Sternum (figs. 272, 472) as in
M. ranomafana
. ABDO-
MEN
(figs. 269, 271, 275–277) as in
M. valterova
, but with slightly smaller book lung covers. GENITALIA: Epigastric region with sperm pore small, rebordered (fig. 271). Palp with bulb-cymbium large, about 0.7 patellatibia length; bulb with dorsal depression (figs. 288–295, 482, map 3).
FEMALE (PBI_OON 03376). Total length 1.82 (1.80–1.82), carapace length 0.78, width 0.68 (0.66–0.68), N 5 2. CEPHALOTHO- RAX (figs. 278–280, 283, 284): Clypeus sloping forward in lateral view, shorter than eye row length (fig. 280). Eye area about 1.3 clypeus length (figs. 280, 283). ABDOMEN (figs. 281, 285–287): Pedicel tube short (fig. 286), scutum dorsal extension slightly less than pedicel diameter (fig. 286). Dorsal scutum smaller than carapace, covering about 0.6 abdomen length and width (fig. 279). Postepigastric scutum weakly sclerotized. LEGS: patella plus tibia I longer than carapace (fig. 280). GENITALIA: Epigynal region weakly sclerotized, receptaculum short and relatively straight, W/L about 0.25 (figs. 296–300, map 4).
