This species is named in honour of Bill Crowe for his role in establishing a “National Acarology Coordinator” position at the Australian Quarantine and Inspection Service. Remarks. The subgenus Philippicheyla was revised by Fain et al. (2002) ; it includes four species along with the new species described above. The new species is close to Cheletomimus filipina ( Corpuz-Raros, 1972 ) and C. notelaeae ( Gerson, 1994 ) . In all these three species, the median setae of the idiosoma are narrowly lanceolate or thickened filiform. The new species is clearly distinguished from C. filipina and C. notelaeae by smooth filiform setae dF of the palpal femur, smooth idiosomal humeral setae c2 , the presence of pseudoanal setae ps3 , setae se located off the propodonotal plate, bases of setae e1 located almost at the same level with bases of e2 , and by the propodonotal shield in the shape of inverted trapezium. In the other two species, setae dF of the palpal femur and humeral setae c2 are narrow/widely lanceolate or thickened serrate, setae ps3 are absent, setae se are located on the propodonotal plate, the bases of setae e1 are located significantly posterior to level of e2 bases, and the propodonotal shield has the posterior margin distinctly longer than the anterior one. Cheletomimus crowei sp. nov. differs from C. filipina also by the presence of a pair of the prominent lateral teeth on the rostrum and by the absence of solenidion on tibia II. In C. filipina , the rostrum is without lateral teeth and solenidion on tibia II is present. It differs from C. notelaeae by the presence of four setae on tibiae II–IV, two setae on genu IV, one seta on femur III, and by setae ao1 shorter than ao2 . In C. notelaeae , tibiae II–IV are with three setae each, genu IV is with one seta, femur III bears two setae, and setae ao1 are distinctly longer than ao2 .
