Tuccioglyphus Horn and Klimov , gen. nov.

Type species Tuccioglyphus setosus Horn and Klimov , sp. nov.

Diagnostic description. Both sexes. Anterior projection of dorsal propodosoma present, weakly developed. Setae se, medium-sized, clearly shorter than 1/2 of body width. Dorsocentral idiosomal setae (si, c1, d1, e1) medium-sized and distinctly flattened, each exceeding half the distance between respective paired setae. Setae c p less than twice as long as c3. Posterior hysterosomal setae h3 and h2 long, distinctly longer than other setae. Coxal setae 4b present. Pouch with opening near insertion points of trochanters II absent. Genu I with two solenidia (σ', σ''). Solenidion σ' I, short, distinctly not reaching half of tibia. Distinct protuberances bearing tibial solenidia φ I–II absent. All leg setae filiform. Trochanteral setae (pR I, II, s R III), and tarsal setae ra I, II, r III, and s III present. On tarsus I, famulus (ε) closely associated with solenidion ω1. Solenidion ω 1 II situated near midlength of tarsus II. Ventral surface between setae wa and s of tarsi I–II without small, sclerotized protuberances.

Female. Rounded plates present posterior to bases of si and se. Posterior ends of coxal apodemes I widely separated from epigynal apodeme; space between them striated, not sclerotized and punctate. Median lip of ovipore striated, not sclerotized and punctate, without distinct incision at anterior tip. Setae ps2 at level of posterior margin of anus. Vestibule of copulatory pore small and inconspicuous. Tarsi with only posterior apicolateral apophyses I present.

Male. Tarsi with the following apicolateral apophyses present: anterior and posterior I, posterior III. Adanal suckers well developed. Heteromorphic males (enlarged legs I and Y-shaped apodemes I) present. Homeomorphic males (legs I not enlarged and apodemes I free) not found.

Differential diagnosis. Similar to Hughesiella ; see key to genera below for the diagnostic characters (couplet 14). Can be distinguished from all pyroglyphids by the presence of flattened, medium-sized dorsocentral setae (si, c1, d1, e1) (i.e., exceeding half the distance between respective paired setae). In other pyroglyphids, these setae are distinctly shorter.

Etymology. The new genus is named for Dra. Edna Clara Tucci (Instituto Biológico, State of São Paulo, Brazil) in recognizing her research on parasitic arthropods attacking Brazilian poultry. The second part of the generic name is derived from glyphus (from the Greek verb γλύφω—to carve, cut out with a knife, engrave), which is commonly used to form compound names for Astigmata . The gender is masculine.
