An undescribed species of the genus Lanceacheyla Xia, Klompen and Childers, 2011 (Acariformes: Prostigmata: Cheyletidae) has been collected from bat guano inside a cave in Bulacan Province Luzon Island Philippines. This species differs from the type species, L. whartoni Xia, Klompen and Childers, 2011, by the lanceolate caudal seta h2 which like the humeral seta c2, is differentiated in shape from the squamiform setae of dorsal shields; presence of horn-like anterolateral projections on protegmen, reticulate (vs. granulate) patterns of tegmen and protegmen; presence of cupules im and ip; and transverse arrangement of anal setae ps1-3 on a half-moon shaped anal plate (vs. longitudinal). The habitat of the Lanceacheyla species from the Philippines differs extremely from that of L. whartoni which was described from leaves of oranges in California. Morphological characteristics are prescribed and illustrated based on the female of this species.
