Crassacarus sialia sp. nov . , details of female. A—palp in dorsal view; B—leg I in ventral view; C—tarsus I in dorsal view; D—tarsus II in dorsal view. Type material . Holotype female ( OSAL 0077574), 3 female and 1 male paratypes ( OSAL 0 0 77575, 0 0 77576, 0 0 77581, 0077587) from Melanerpes formicivorus (Swainson) ( Piciformes : Picidae ) [scaly area in ear], USA : Kansas, Johnson Co., Craig, 38.97°N 94.82°W (GNIS-USGS), 10 December 1962 , coll. W.W. Moss. Type deposition . Holotype and most of paratypes in OSAL , 1 female paratype in ZISP . Additional material. Two males ( OSAL 0 0 77583, 0083603) from Melanerpes formicivorus, USA : Kansas, Douglas Co., Lawrence, 38.97°N 95.24°W (GNIS-USGS), 16 December 1962 , coll. W.W. Moss. Etymology . The specific epithet is derived from the generic name of the host and is a noun in apposition. Hosts and distribution . Melanerpes formicivorus ( Piciformes : Picidae ) from USA (Kansas) (present paper). Differential diagnosis . Females of Crassacarus melanerpes sp. nov . differ from all other species of this genus by the short palps being only 1.3 times longer than wide (vs. palps 1.5–1.8 longer than wide), and some setae of legs III and leg IV being short and spur-like (vs. all setae long, filiform).
