Eurycaulis OPITZ nov.gen.

Type species: Eurycaulis anaxeis OPITZ. By present designation.

D i a g n o s i s: The combination of 10 antennomeres, absence of asetiferous elytral punctures, and very broad phallobasic apodeme will distinguish the members of this genus within Peloniinae .

Synapotypic characteristic: Phallobasic apodeme very broad.

D e s c r i p t i o n: Size: Length 5.5 mm; width 2.0 mm. Form: Oblong rectangular, about 3 times longer than broad. Vestiture: Dorsum profusely vested with short pubescence; antennal funicle moderately setose, capitulum profusely vested with micro- sensilla; elytra abundantly vested with short light setae. Head: Cranium subquadrate, profusely indented with setiferous punctures; frons narrower than eye; gula large, trapezoidal, sutures converge, post-gular plate with two setose processes; labrum shallow, broadly incised distally; mandible, body stout, anterior dens subacuminate, medial, and posterior dens moderately developed, penicillus well developed; maxilla, terminal palpomere subdigitiform; labium, terminal palpomere subdigitiform; eyes large, coarsely facetted, ocular notch not very deep; antenna capitate, comprised of 10 antennomeres, funicular antennomeres become shorter as they approach capitulum. Thorax: Pronotum slightly transverse; dorsolateral carina extends to middle of pronotal tubercle, posteriorly carina extends to pronotal posterior angles where confluent with pronotal hem; disc slightly convex and finely punctated; side margins with slightly-developed tubercle; prointercoxal process linear; pronotal projections acuminate, they do not approximate prointercoxal process; elytral disc devoid of asetiferous punctures, epipleural fold prominent, narrowly extended to elytral apex, elytral anterior margin not carinate; legs, prothoracic femora not swollen; tibial spur formula 0-2-1, tarsal pulvillar formula 3-3-3, unguis with basal denticle. Abdomen: Pygidium scutiform; aedeagus as in Fig. 240.

D i s t r i b u t i o n: Known from Bolivia.
