Treatment

Merizocera kurunegala Li sp. nov. Figures 19 View Figure 19 , 20 View Figure 20 , 52 View Figure 52

Type material.

Holotype: male (IZCAS), near Arankele Cave (7°38.42'N, 80°25.33'E, elevation 114 m), Kubukwewa Village, Hiripitiya, Kurunegala District, Northwestern Province, Sri Lanka, 11 October 2014, S. Kosala leg. Paratype: 1 female (IZCAS), same data as holotype.

Etymology.

The specific name refers to the type locality; noun in apposition.

Diagnosis.

Males resemble M. peraderiya sp. nov. and M. picturata but can be distinguished by a relatively shorter bulb (Fig. 19B View Figure 19 ) (1/2 length of that in M. peraderiya sp. nov. (Fig. 25B View Figure 25 ) and M. picturata ), an evenly bent embolus in M. kurunegala sp. nov. (Fig. 19B View Figure 19 ) and M. picturata (vs. an angularly bent embolus in M. peraderiya sp. nov. (Fig. 25B View Figure 25 )), furcate conductor in M. kurunegala sp. nov. (Fig. 19B View Figure 19 ) and M. peraderiya sp. nov. (Fig. 25B View Figure 25 ) (vs. conductor not furcate in M. picturata ), conductor arising medially in M. picturata (vs. conductor not arising medially in M. kurunegala sp. nov. (Fig. 19B View Figure 19 ) and M. peraderiya sp. nov. (Fig. 25B View Figure 25 )). The females can be distinguished by having sessile wavy spermathecae in M. kurunegala sp. nov. (Fig. 20A View Figure 20 ) and M. picturata (vs. a pair of S-shaped spermathecae in M. peraderiya sp. nov. (Fig. 26A View Figure 26 )).

Carapace circular, brownish, with dark brown marks laterally and dark brown median stripe on anterior half (Fig. 20C View Figure 20 ). Fovea shallow. Thoracic region distinctly elevated medially.

Palp (Fig. 19A-D View Figure 19 ): femur slender, thrice longer than patella, patella not swollen; tibia slightly swollen proximally, twice wider and half length of femur; cymbium with distal protrusion, half length of femur, length ratio of dorsal elongation and cymbium 0.64; bulb pale yellow; embolus dark, evenly bent, twice as long as bulb; conductor trifurcate with two pointed upwards, and third pointed downwards, stem of conductor thrice wider than that of embolus.
