Collectors: D. Evangelista, M. Davis, M. Johnney, M. Carter, O. Ambrose. 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 . Figure 1. Lamproblatta ancistroides Rehn, 1930 . Adult male.
