MALE: Unknown.

Diagnosis. Most closely related to X. feehani , differing by POL/OOL, extension of frontal patch and facial striae, sculpture of posterior T3, color of coxae, reduction of posterior row of foveae of mesopleural carina and foveolate sulcus along metapleural carina.

Etymology. Named after Béla Kalocsa, who was the first teacher in biology of the senior author.
