Ctenocolletacarus longirostris Fain, 1984: 79, Figs 1-6, 10 (holotype HDN, ex Ctenocolletes nicholsoni metasomal acarinarium, Western Australia (200 km N of Geraldton), in WAM; paratype HDNs in WAM, WADA, IRSNB, BMNH; included in key); Fain & Houston, 1986: 69, Figs 1-6, 11-17 (description of female, protonymph, and larva; rearing experiments from protonymphs found inside a single cell of Ctenocolletes nicholsoni yielded phoretic deutonymphs of both of C. longirostris and C. grandior; bee females occupying the nest were all carrying deutonymphs of C. grandior; mention that what they refer to under C. longirostris may be a mix of C. longirostris and C. grandior); Houston, 1987: 460, Fig. 1 (SEM picture of mites in acarinarium; detailed description of host acarinarium; observation on mite biology inside host bee nest; mention that specimens identified as "C. longirostris" may be a mix of C. longirostris and C. grandior) .
Material (show database records).
Biology. Deutonymph are found phoretic in circular metasomal acarinaria on the lateral margins of metasomal tergites 3 and 4. Houston (1987) gives a detailed biological account of "C. longirostris" (which may partially include C. grandior).
Identification. Known from phoretic deutonymphs, females, protonymph, and larva (Fain, 1984; Fain & Houston, 1986). Feeding stages may be indistinguishable from those of C. grandior. See key to species of Sancassania (Ctenocolletacarus) based on phoretic deutonymphs.
Distribution (show map). Australia: Western Australia (type locality).
Ctenocolletes nicholsoni (Cockerell, 1929) (type host)
