description: Marioglyphus Klimov, gen. n.
Type species Hughesiella valerioi Vargas and Smiley
Diagnostic description. Projection of dorsal propodosoma present, well developed, with simple or very slightly bilobate end. Setae se medium-sized and setae h2 long; all other setae very short and represented by microsetae (except h 3 in male being medium-sized). Dorsocentral idiosomal setae (si, c1, d1, e1) microsetae, not flattened, each distinctly shorter than half distance between respective paired setae. Setae c p and c3, microsetae, subequal. Coxal setae 4b present. Pouches opening near insertion points of trochanters II absent. Genu I with two solenidia (σ', σ''). Solenidion σ' I, short, not reaching half-length of tibia. Distinct protuberances bearing tibial solenidia φ I–II absent. All leg setae filiform (except for spiniform s III and sucker-like d and e IV in male). Trochanteral setae (pR I–II, sR III), and tarsal setae ra I–II, r III, and s III present. On tarsus I, famulus ε distinctly moved basally from solenidion ω1. Solenidion ω 1 II paramedial. Ventral surface between setae wa and s of tarsi I–II without small, sclerotized protuberances.
Female. Rounded plates posterior to bases of si and se absent. Posterior ends of apodemes I widely separated from epigynal apodeme; space between them sclerotized and punctate (no striation). Median lip of ovipore sclerotized and punctate (not striated), with 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: posterior I and III (anterior apophysis I absent). Tarsal seta s III spiniform. Adanal suckers vestigial, represented by simple sclerotized rings. Heteromorphic and homeomorphic males present.
Differential diagnosis. The new genus is similar to Hughesiella, but differs by setae se and h2 which are markedly longer than other idiosomal setae and flattened (uniformly short, microsetae, filiform in Hughesiella); setae ps2 are present in both sexes (absent in Hughesiella); male tarsi I and III each with posteroapical apophysis (lack apical apophyses in Hughesiella). See also key to genera below (couplets 14 and 15).
Note. This genus is monotypic.
Etymology. The new genus is named after Dr. Mario Vargas (Center for Research and Diagnostics in Parasitology, School of Microbiology, University of Costa Rica, San José, Costa Rica), who originally discovered and described Hughesiella valerioi. 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.
