Diagnosis. Specimens of this genus superficially resemble those of Pelonides . Parapelonides differs by having asetiferous punctation on the elytral disc (compare Figs. 22 and 23 ), capitular antennomeres that are not lobed, and the ungues are smaller (compare Figs. 19–21 ).

Redescription. Size: Length 4.0–8.0 mm; width 1.5–3.0 mm. Form ( Fig. 25 ): Oblong suboval (about 2.5X longer than broad), body shallow. Vestiture: Dorsum profusely vested with pale or black pubescence; antenna profusely setose, capitular setae very densely packed and short;

elytra with 1° and 2° setae. Head ( Figs. 1–3 , 16, 17 ): Cranium transverse, frons wider than width of eye, profusely indented with small setiferous punctation; gula ( Fig. 2 ) large, triangular, sutures converging anteriorly, with 2 setose postgular processes; labrum ( Fig. 11 ) shallow, incised distally, tormal processes confluent, epipharyngeal plate small; mandible ( Fig. 8 ) stout, anterior dens acuminate, medial dens well-developed, posterior dens poorly developed, penicillus large; maxilla as in Fig. 9 , laterolacinia present, terminal palpomere rectangulate; labium as in Fig. 10 , ligula deeply incised, ligular lobes not well-developed, terminal palpomere rectangulate; eyes small, ommatidia very small, ocular notch large; antenna comprised of 10 antennomeres, capitate ( Fig. 5 ), pedicel spheroid, funicular antennomeres subfiliform, capitulum very long, capitular antennomeres not lobed. Thorax: Pronotum ( Figs. 6, 7 ) quadrate or slightly elongated, disc slightly convex, side margins may be slightly dilated, dorsolateral carina complete, confluent with pronotal hem beyond hind angle of pronotum, with partial commissure, prointercoxal process narrow ( Fig. 6 ), not expanded distally, pronotal projections very short, acuminate, not approximating prointercoxal process; elytron prominently sculptured with asetiferous punctures ( Fig. 22 ), epipleural fold wide and in ventrolateral position, elytral anterior margin not carinate; metathoracic wing as in Fig. 4 , wedge cell open; metendosternite with furcal lamina, furcal anterior plate acuminate or

incised; profemora not swollen, anterior margin of protibia not spinous; tibial spur formula 0-2-2, tarsal pulvillar formula 3-3-3, ungues with basal swelling. Abdomen: Aedeagus ( Figs. 29–31 ) shorter than length of abdomen, distal region of phallobase lobed, lateral lobes short, not fimbriate, tegmen not reduced ventrally, phallobasic struts confluent with phallobasic apodeme, phallobasic rod present, phallic plates broad, both margins spinose; spicular fork well developed, spicular apodemes fused at distal third, intraspicular plate linear.

Distribution. This genus is known from the southwestern USA to Honduras.
