Ascetomylla porzanae (Bochkov et Galloway, 2004) comb. n.

Syn. Syringophilopsis porzanae Bochkov et Galloway, 2004

The species Syringophilopsis porzanae Bochkov et Galloway, 2004 was described from Porzana carolina (Linnaeus) ( Gruiformes : Rallidae ) based on material from Canada ( Bochkov and Galloway 2004). Possibility of studying the type material (female and male) enabled the designating of the real status of this species. This taxon has characters that perfectly correspond to those of Ascetomylla Kethley, 1970 , e.g. the leg setae dFII, dFIII and dFIV are absent and the propodonotal shield is divided longitudinally. Mites of the genus Syringophilopsis have the legs with full complement of setae and the propodonotal shield is entire, and therefore, we reassigned S. porzanae to the genus Ascetomylla .

M a t e r i a l e x a m i n e d: 2 females from Porzana caro- lina (Linnaeus), Canada, Manitoba, Delta Marsh, Univer- sity Field Station, 19 May 2000, T.D. Galloway and D. Holder coll. This material was borrowed from A.V. Bochkov (Zoological Institute of the Russian Academy of Sciences, St. Petersburg, Russia).

Remarks. To this time, the genus Ascetomylla was represented only by the type species A. gallinula Kethley, 1970 described from Gallinula chloropus (Linnaeus) ( Rallidae ) from the Union of South Africa ( Kethley 1970). The second species, transferred to this genus here, can by distinguished from A. gallinula by the following characters: in females of A. porzanae , the length ratio of setae vi:ve:sci is 1:2:2.5, the longitudinal branch of the peritremes has 11–14 chambers. In males the length ratio of setae l1:d2:l2 is 2:1:1. In females of A. gallinula , the length ratio of setae vi:ve:sci is 1:3:3, the longitudinal branch of the peritremes has 18–19 chambers. In males the length ratio of setae l1:d2:l2 is 1:1:1.
