Surface / Color: Dorsal surface of head, pronotum, and elytra setose; setae varying from short bristles to longer setae; setae erect or subdepressed. Color testaceous to dark castaneous, variable within species. Head: Clypeus varying from semicircular to subtrapezoidal, often sexually dimorphic in length (longer in females). Frontoclypeal suture indistinct but generally discernible. Frons simple or variably armed with tubercles, horns, or carinae. Mentum variable between species. Mandibles moderately large, externally rounded to angulate, visible beyond labrum in dorsal view. Labrum strongly projecting between mandibles, setose. Antenna with 10 antennomeres; 3 - antennomere club nearly round, pubescent. Pronotum: Surface densely punctate, punctures fine to moderate, each with or without a distinct setigerous tubercle anteriorly; setae moderately long. Elytra: Striae (except sutural) not impressed, uniserially punctate; punctures moderate to large, moderately deep, round, lacking setae. Intervals tuberculate; tubercles fine to moderate, forming irregular rows, setigerous; setae variable in length. Legs: Protibia with 3 external teeth increasing in size distally; occasionally with apical internal tooth or " thumb " produced beyond tarsal insertion. Metafemur usually simple with slightly produced rounded lobe, occasionally armed with 1 large tooth or several small, irregular teeth on dorsal or ventral posterior margin before apex. Metatibia form variable from slender and subcylindrical to broad and flattened. Abdomen: Stridulatory peg, if present, near anterolateral angle of propygidium (necessary to unlock elytron and depress abdomen to view). Propygidial margin with 2 tubercles on posterior margin.	en	Paulsen, M. J., Ocampo, Federico C. (2012): The Ochodaeidae of Argentina (Coleoptera, Scarabaeoidea).

8F9AA8A91135D526B71DB3F346945925.taxon	diagnosis	Diagnosis. Parochodaeus pudu (Fig. 15) is the only species of Parochodaeus with two small horns on the vertex of the head (Fig. 1). Because of this, the species is immediately recognizable. In Parochodaeus bituberculatus (Erichson) of Peru the frontal structures are not horn-like, being instead two short, transverse carinae.	en	Paulsen, M. J., Ocampo, Federico C.

2EC23AEDA1E5655181306F027A2362B4.taxon	diagnosis	Diagnosis. Parochodaeus stupendus (Fig. 17) is the only species of Parochodaeus to exhibit a doubly-toothed posterior margin on the metafemur. The tooth on the ventral surface is fairly common in ochodaeids, but the second tooth on the dorsal surface is unique. The toothed metatrochanter and strongly curved metatibiae (Fig. 7) are not found in any other species in Argentina, or elsewhere. The strongly produced ' thumb' (internal apical tooth) is also species specific. The female is unknown.	en	Paulsen, M. J., Ocampo, Federico C.

2EC23AEDA1E5655181306F027A2362B4.taxon	etymology	Etymology. The specific epithet ' stupendus' is Latin meaning " causing astonishment or wonder ". With several autapomorphies not seen in other species of the genus, Parochodaeus stupendus is arguably the most wondrous ochodaeid in the New World.

AD0B49F4F743D8E491FE8D3BAB4F139B.taxon	diagnosis	Diagnosis. The only known species in Gauchodaeus is an elongate ochodaeid with no elytral closing mechanism, and therefore can be quickly distinguished from the more globular Parochodaeus species with dentate elytral apices and a bituberculate propygidium. The genus is most similar to the genus Synochodaeus of southern Africa but is distinguished by the characters discussed above.	en	Paulsen, M. J., Ocampo, Federico C.

A3B1A40FF6176FEA94E18E2C13981073.taxon	diagnosis	Diagnosis. The elongate body of this species (Fig. 17) is unlike that any other South American ochodaeids, which are in a different subfamily. The pectinate mesotibial spur, lack of propygidial tubercles, and simply rounded elytral apices will separate it from Parochodaeus or any other scarabaeoids.	en	Paulsen, M. J., Ocampo, Federico C.
