Figures 44 , 52 Merizocera sp. 158: Li and Li 2018 (molecular data). Type material. Holotype : female (IZCAS), Udakirinda Cave 1 ( 6°50.24'N , 81°3.85'E , elevation 855 m), Koradogolla Village, Ella, Badulla District, Uva , Sri Lanka , 3 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. Females resemble those of M. yala sp. nov. by having twisted stalked spermathecae but can be distinguished by having two pairs of twisted stalked spermathecae, with one end ellipsoid and the other end bifurcately globose (Fig. 44A ) (vs. only globose distal ends (Fig. 49A )).
