Literature records. PERU: Cuzco: Machupicchú , 2000m, XII.1947 (Dr. W. Weyrauch) ( Bechyné 1956) .

Description of genitalia. Spermathecal pump ( Figure 8E ) clearly separated from receptacle, about half as long as receptacle, slightly arched, with top rounded. Apex of spermathecal pump flattened; length about one-fifth of spermathecal pump. Receptacle elongate, constricted just before and at spermathecal pump, forming clear neck; maximum width situated at about middle of receptacle. Male genitalia not available for study.

Diagnosis. Rhynchasphaera latipleura can quite easily be separated from the two other species of this genus by the elytral coloration alone (see key above, Figure 8 ). Additionally, R. latipleura distinguishes from R. basisticta by the more matte, deeply punctate and evenly rounded elytra ( Figure 8A&B ). Furthermore, R. latipleura can be separated from R. orophila by the clearly punctate frons ( Figure 8C ).
