Diagnosis
Myrmarachne hamata sp. nov. can be easily distinguished from other congeners by the RTA curved into a reverse C-shape medially and forming a hook at the distal end in retrolateral view ( Fig. 7C, G View Fig ), whereas without similar RTA in others ( Metzner 2023).
Etymology
The specific name comes from the Latin ‛ hamatus ’, which means ‛hook-shaped’, and refers to the RTA forming a hook at distal end in retrolateral view; adjective.
