Antillocladius calakmulensis Mendes, Andersen et Saether

Antillocladius calakmulensis Mendes, Andersen and Saether, 2004: 32 , Fig. 4 .

Material examined: Type material as in Mendes et al. (2004).

Diagnostic characters: The male can be separated from all other members of the genus by having a virga consisting of 6 short spines; apical setae on the wing membrane; squama with a few setae; short costal extension; scalpellate acrostichals in mid scutum; anal point long, triangular, with strong lateral setae; and inferior volsella prominent with anterior digitiform projection equally long as and partly covering rounded posterior lobe.

Distribution: The species is known from Calakmul Biosphere Reserve, a large rainforest reserve on the Yucatan Peninsula in Mexico.
