| abstract | A new species, Lanceacheyla filipina (Acariformes: Prostigmata: Cheyletidae) from bat guano inside a cave in Bulacan Province, Luzon Island, Philippines is described. This species differs from the generic type species, L. whartoni Xia, Klompen & Childers, 2011, by the lanceolate caudal seta h2 which, like the humeral seta c2, is differentiated in shape from the squamifrm setae of dorsal shields, presence of hornlike anterolateral projections on protegen, reticulate (vs. granulate) pattern 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). Morphological characteristics were described and illustrated based on the female of this species. |
