Malagiella ranavalona , new species Figures 329–344 , 487 , maps 1, 2, 4; table 1

TYPE: Female holotype from forêt autour du Palais de la Reine Ranavalona, env., Ambohimanga, 20 km N Antananarivo, 1400 m, Antananarivo Province, Madagascar (9 Dec 1989, B. Hauser), deposited in NHMB (Bern-Mad-89/59, PBI _OON 03637).

ETYMOLOGY: The species is named after the type locality.

DIAGNOSIS: This species differs from others in the group by the moderately sinuous receptaculum, W/L 5 0.76 (figs. 339–344).

MALE: Unknown.

FEMALE (PBI_OON 03637): Total length 1.61 (1.50–1.61), carapace length 0.60, width 0.49, N 5 2. CEPHALOTHORAX (figs. 329 –331, 333–335): Eyes small, subequal; eye area about 0.40 carapace width, subequal to clypeus length (figs. 331, 334). ABDOMEN (figs. 332, 336–338): Pedicel tube short (fig. 337), scutum dorsal extension short, about 0.3 pedicel diameters. Dorsal scutum weakly sclerotized, pale orange, covering about 0.5 abdomen length, 0.3 abdomen width (fig. 330). LEGS: Patella plus tibia I nearly as long as carapace. Leg spination (in addition to typical pattern): tibia IV v0-0-2. GENITALIA: Postepigastric scutum weakly sclerotized; receptaculum moderately sinuous, W/L 5 0.76 (figs. 341–344).

OTHER MATERIAL EXAMINED: MADA- GASCAR: Antananarivo Province: Ambohimanga, 20 km N Antananarivo, forêt autour du Palais de la Reine Ranavalona, env., 1400 m, 9 Dec 1989 (C. Lienhard, NHMB Bern-Mad-89/60, PBI_OON 03919), 1♀.

DISTRIBUTION: Known only from the type locality in central Madagascar.

Fig. 487. Size variation in Malagiella measured as a function of carapace length to carapace width. Plot is based on measurements of 26 male specimens (‘‘x’’) and 30 female specimens (‘‘o’’). Blue lines enclose male values for a given species and red lines female values; disjunct conspecific readings are connected by straight lines. Green dotted lines enclose the three species groups. Brown dashed lines refer to the size of female DS, with the large dashes (upper right) enclosing species with the largest scutes and small dashes (lower left) those with the smallest.
