Lengths of setae : vi 180, ve 260, si 405, se 405, c1 450, c2 430, d1 445, d2 410, e2 395, f1 90, f2 455, h1 105, h2 480, ps1 65, ps2 65, g1 75, g2 75, ag1 310, ag2 180, ag3 300, l’RIV 145, 3b 145, 3c 190. Etymology. The name “ trogoni ” refers to the generic name of the host – Trogon . Type material. Female holotype and 1 female paratype from Trogon citreolus Gould ( Trogoniformes : Trogonidae ); MEXICO , Jalisco, Chamela Biological Station of UNAM, N 19°29’52” W 105°2’33” , 19 May 2008 , coll. S.V. Mironov & P.B. Klimov (Field no. SVM 08-0519-11/3). Type material deposition. Female holotype deposited in UNAM, female paratype in ZISP. Additional material. One female from secondary quill of Trogon melanocephalus Gould ; COSTA RICA , Finca Taboga near Canas, 10 February 1970 , coll. D.E. Johnston. Mite specimen is deposited in FMNH. Differential diagnosis. Syringophilopsis trogoni sp. nov . belongs to the group “ turdi ” and is similar to S. rusticus Skoracki, 2004 described from Hirundo rustica ( Passeriformes : Hirundinidae ) in Poland (Skoracki 2004). In females of both species, the hypostomal apex bears two pairs of protuberances, and genital setae are distinctly shorter than agenital setae. This new species differs from S. rusticus by the following characters: in females of S. trogoni , the hysteronotal shield is absent; setae se are situated distinctly anterior to the level of setae c1 ; the pygidial shield is apunctate; the length ratio of setae ag1 : ag2 : ag3 is 1.7:1:1.7, and the length of setae l’RIV is 145. In females of S. rusticus , a pair of the hysteronotal shields is present; setae se and c1 are situated at the same transverse level; the pygidial shield is punctate; the length ratio of setae ag1 : ag2 : ag3 is 1:1:1, and the length of setae l’RIV is 60–70.
