Recognition
de Remes Lenicov and Walsh (2013) describes this genus and species as “lender, compressed, rather long-legged, pale with distinctive pair of longitudinal dark brown to black stripes on face and several maculations on thorax and abdomen. Head with a shallow, small subapical areola on vertex continued into a distinctive simple median carina extended throughout frons and postclypeus. Male genitalia with a single subacute median process margined with a smaller rounded tooth on ventral margin of the pygofer.”
