Uroctea limbata – Zamani et al. 2017b: 60 (misidentification).

Diagnosis

Uroctea gambronica sp. nov. is closest to U. grossa and U. thaleri . It differs from both species by its short, straight, subconical TL of the male palp (vs long, curved and subcylindrical), the basal part of its MAb1 making a 135° hook ( Fig. 7F , vs gently curved in U. grossa and straight in U. thaleri ), its smaller, subrectangular terminal section of MAb2 (vs large and fan-shaped), and its sharply toothed retrolateral lobe of MAb2 (vs bluntly toothed). It further differs from U. grossa by its smaller size and its lower number of ti spines ( Fig. 4H vs Fig. 4F ). It also differs from U. thaleri by its sharply angled MAb2 (vs smoothly bent, Fig. 7D vs Fig. 7G ).

Etymology

The new species is named after Gambron, the former English traders’ name for Bandar Abbas, the type locality of the species.
