Etymology.
The specific name is a combination of ‘ long ’ and ‘ hamata ’, referring to the long and hook-shaped conductor; adjective.
Diagnosis.
The new species is similar to C. eburnata Wang, 1994 (Wang et al. 2019: 354, figs 9 A – D, 10 A – G) in having similar shaped retrolateral tibial apophysis, long and strong embolus, strong and hook-like conductor, posteriorly located epigynal atrium, but differs from the latter by the conductor with a long, acicular and C-shaped end (Figs 5 A, B, 6 C – E) (vs. short and blunt end in C. eburnata), the C-shaped copulatory ducts and gourd-shaped spermathecae (Figs 5 D, 6 G) (vs. rod-shaped and spherical C. eburnata).
