Eucharitolus geometricus ; Monné, 1985: 547; 2005: 38 (cat.).

Redescription. Male. Integument dark brown. Body with predominance of brown pubescence. Antennomeres III–IV and VI bicolored with basal half yellow and apical half dark-brown, other antennomeres dark-brown. Scutellum covered with yellow pubescence. Elytra with narrow elongate yellow bands paralleling suture and another diagonal band starting at external margin of anterior third and extending to elytral suture at posterior third then continuing transversally to external margin near apex.

Upper eye lobes well separated, distance between them equal to four times the width of a lobe. Antennae exceeding elytral apices at antennomere VII. Scape 1/3 longer than antennomere III, III–XI gradually decreasing in length, XI the length of antennomere III. Antennomeres III–VII thick, antennomeres VIII–XI noticeably thinner. Pronotum deeply, coarsely punctate, more so on disc. Prosternal process about 1/5 as wide as procoxal cavity. Mesosternum depressed. Mesosternal process 1/5 width of mesocoxal cavity.

Elytra approximately 3.5 times as long as prothorax; surface uniformly punctate, deeper in the anterior. Humeri slightly projected anteriorly. Apices truncate.

Metatarsomere I slightly longer than II–III together. Apex of urotergite V emarginate with angles produced; urosternite V with the apical margin semicircularly emarginate.

Measurements, in mm. male. n= 1. Total length, 9.5; prothorax length, 1.9; prothorax width at widest point, 2.7; elytral length, 6.6; humeral width, 3.6.

Geographical distribution. Peru and Bolivia

Specimens examined. PERU, Junin: Chanchamayo, male, 20.X.1947, Zellibor leg (MNRJ).

Remarks. This species is characterized by its distinctive elytral pattern ( Fig. 6 ), by the distance between upper ocular lobes equal to four times the width of the lobe and varying thickness of its antennomeres (III–VII much thicker than VIII–XI).
