Morphological identification

These specimens were identified to genus by the valvate subgenital plate in the female and lack of wings. The specimen was further identified to species as follows: it differs from L. mimetes in the relatively narrower inter-stylar region ( Rehn 1930); it shows less acute productions on the lateral tergites, and wider supra-anal plate than in L. albipalpus Hebard 1919 ; it is larger than L. albipalpus Hebard, 1919 and L. meridionalis ( Bruner 1906) ; the female is larger than in L. romani Rehn, 1930 . All measurements can be found in Table 1. In all other ways, this species agrees with the description of L. ancistroides Rehn, 1930 .

Collection/ecological information

Although we only report three individuals here this species was numerous in our collection (43 total adults). Most specimens were collected by hand on low lying vegetation at night. A few other individuals were collected in pitfall traps baited with beer.
