Oxypyge mesites ( Chamberlin, 1922) comb. nov.

Oxypygides mesites Chamberlin 1922 . Proceedings of the U.S. National Museum. 60(8):25, pl. 10, figs. 11,12; pl. 11, figs. 1,2. Hoffman 1999.

Type material examined: Male holotype and female paratype from Guatemala, Cacao, coll. O.F. Cook, April 1906 (deposited in the United States National Museum, Smithsonian).

Additional material examined from near type locality: Male from Guatemala, Dept. Izabal, Finca Las Ilusiones (along Highway CA9), 26.8 km bearing 220 true N from Puerto Barrios, elev. 95 m, coll. J. Bond, 4 June 2000 (deposited in the Field Museum of Natural History).

Male holotype: Specimen quite damaged (numerous segments detached and broken). Color of preserved material badly faded­­head, antennae, and collum very light yellowish brown ( Fig. 12 ). Segments appear to have had some banding. Chamberlin (1922) described the coloration of this specimen as black from above with the posterior of each segment fulvous to chestnut.

Antennae with only four sensory cones, flattened laterally, incrassate distally. 14–13 labral setae, clypeal groove dark and distinct, 33 ocelli. Width at collum 5.40, ~50 ring segments. Distinct scobinae on numerous segments, apparently diminishing in size posteriorly. Tarsi lacking ventral pads. Epiproct short, not extending beyond paraprocts. Anal valves elongate, with dorsal hook ( Fig. 13 ). Hypoproct long, triangular with blunt terminal end, not extending beyond paraprocts.

Anterior gonopod as illustrated in Figs. 14, 15 . Sternum ( Fig. 15 ), Cx and Tp as in other rhinocricids ( Fig. 14 ). Posterior gonopod telopod (Tp, Fig. 16 ) long and spatulate distally with a membranous interior. Seminal canal (Sc) visible extending from the Cx to the solenomere Sm. Seventh segmental ring posteroventrally modified as a postgenital bar to accommodate gonopods.
