( L 40, L 9), H. ohiyaensis   sp. nov. ( L 30) and Macaroeris nidicolens (Walckenaer, 1802)   ( L 17) in Sri Lanka. See text for details.

Diagnosis

This species can easily be distinguished from B. afra Szüts, 2004   by the high carapace with steeper thoracic slope, a thicker and longer embolus, copulatory openings anterior to the spermathecae, a large distance between copulatory ducts and the presence of a posterior epigynal plate with a median depression, and from B. heterospinosa   by broader copulatory ducts, a comparatively shallow median indentation of posterior epigynal plate and a thicker embolus.

Etymology

The species is named for Mohandas Karamchand Gandhi (1869–1948). He was the pre-eminent leader of the Indian Independence Movement in British-ruled India, eventually paving the way for independence of Sri Lanka as well.

COLOR AND BODY. Reddish brown carapace with punctured reticulate microsculpture ( Fig. 3 View Fig. 3 A). Chelicerae dark brown with two promarginal and four retromarginal teeth. Labium reddish brown with yellowish brown margin. Elevated ocular area blackish brown, median ocular quadrangle much broader than long and little wider behind than in front. Eye ratio AME > PLE> ALE> PME. Sternum oval-shaped, brownish yellow with sparse brown hairs, edges reddish brown. Prosoma longer than wide with thoracic fovea. Posterior margin of prosoma steep and slightly truncated ( Fig. 3 View Fig. 3 A). There are black stripes made up of minute tubercles behind PLEs.

LEGS. First pair of legs more strongly modiFed in males than females, with elongated coxa, trochanter and patella. Patella and tibia with fringe of thick, long, black bristles ( Fig. 3 View Fig. 3 A). Leg I dark brown except for pale yellow tarsus, other legs yellowish brown. Tibia I with 4 prolateral and 3 retrolateral spines, metatarsus I with 2 pairs of Fne, long spines. Legs III and IV spineless.

PALP. Relatively simple. Cymbium and palpal tibia pale yellow, but coxa, femur and patella dark brown. Pyriform tegulum ( Figs 3 View Fig. 3 C – D, 4 A – B). Thin and short embolus, tip of embolus slightly bent ( Figs 3 View Fig. 3 C, 4 A), tibial apophyses hook-shaped and strongly bent towards venter.

Female

MEASUREMENTS. BL 3.20, CL 1.78, PW at PLEs 0.77,AL 1.40,AW 0.93. Eye Feld: Diameter of AME 0.24, PLE 0.14, ALE 0.11, PME 0.03, PME-PME 0.65, PLE-PLE 0.73, ALE-PME 0.30, ALE-PLE 0.46.

COLOR AND BODY. Similar to male except abdomen with four light brown, longitudinal stripes converging near spinnerets; less strongly modiFed Frst pair of legs ( Figs 2 View Fig. 2 A – B, 3 View Fig. 3 B); leg spination resembles males except in tibia II which has a prolateral and a ventral spine.

EPIGYNUM. Circular hollow copulatory openings above the level of spermathecae ( Fig. 4 C – D). Long and broad copulatory ducts bent over 180°. Somewhat rounded accessory gland- like structures in front of spermathecae ( Fig. 4 C – D). Large and globe-like spermathecae. Posterior margin of epigynal plate with a median indentation ( Figs 3 View Fig. 3 E, 4 C – D). Fertilization ducts lanceolate, originating from anterior wall of receptacles.
