Genus Corvitorotroglus gen. nov.

Diagnosis. FEMALE. Moderately medium or large mites (body length 1105–1145). Gnathosoma. Hypostomal apex bearing pair of bill-like protuberances. Two pairs of hypostomal lips present. Lateral hypostomal teeth absent. Movable cheliceral digits with 3 teeth each. Peritremes M-shaped with distinct chambers. Stylophore constricted posteriorly. Idiosoma. All idiosomal setae smooth. Propodonotal shield entire. Setal pattern of propodonotal region with 6 pairs of setae arranged 3–2–1. Hysteronotal shield fused to pygidial shield, variable in shape. Setae d1, d2, e2, f2, and h2 long, f1 and h1 short. Genital and anal series with 2 pairs of setae. Aggenital series with 5–6 pairs of setae. Legs. Apodemes I divergent, fused to apodemes II. Apodemes I and II different in size and shape. Legs with full complement of setae. Claws subequal, without basal angle.

MALE. As in female except chelicerae edentate and setae d1 and e2 short.

Type species. Corvitorotroglus alpha sp. nov.

Host order. Passeriformes

Etymology. The name Corvitorotroglus refers to the host family name, Corvidae , and to the closely related quill mite genus Torotrogla .

Differential diagnosis. Corvitorotroglus gen. nov. is closely related to the genus Torotrogla Kethley associated with passerine birds. In both genera, the legs have a full complement of setae, the aggenital series has more than 3 pairs of setae, and apodemes I are divergent and fused to apodemes II. It differs from Torotrogla in the following characters. In females of Corvitorotroglus gen. nov., apodemes I and II differ from each other in shape and size ( Fig. 8 ), and the hysteronotal and pygidial shields are fused. In females of Torotrogla , apodemes I and II are similar in shape and size ( Fig. 13 ), and the hysteronotal shield is absent or reduced to two small sclerites bearing bases of setae d1. This new genus also differs from the monotypic genus Trypetoptila Kethley known from ciconiiform hosts ( Kethley 1970) by the absence of tarsal setae vs’III.
