Neoeutrypanus dentatus sp. nov.

( Figs. 21–24 )

Description. Male. Integument dark-brown. Pubescence brown. Base of antennae covered by white pubescence. Pronotum with narrow median longitudinal fascia of grayish pubescence at each side, on anterior third a yellowish oblong spot; laterally with band of yellowish pubescence that reaches prosternum. Basal half of elytra with longitudinal rows of irregular spots of yellowish pubescence. Distal half with transverse band of yellowish pubescence. Apex with white pubescence. Tarsomere I-II covered with white pubescence.

Distance between upper lobes subequal to width of upper lobe. Antennae exceeding elytral apices at antennomere VI, with erect, sparse setae, mainly in ventral face and at apex. Scape and antennomeres III-V subequal in length, antennomeres VI–XI decreasing slightly in length. Antennomeres IV-V with small tooth on inner face of apex. Prothorax armed with rounded lateral tubercles situated at posterior third. Pronotum with basal row of punctures. Prosternal process narrowed at middle, width at narrowest point equal to 1/5 of procoxal cavity width. Mesosternal process truncate at apex, subequal in width to mesocoxal cavity. Posterior apex of pro- and mesosternal process, median region of metasternum, coxae and first urosternite surface covered by dense yellow pubescence.

Elytra almost 4 times as long as prothorax, basal half with coarse punctures. Humeri prominent, rounded. Lateral carina restricted to basal half. Apices truncate, slightly sinuous.

Metatarsomere I 1.5 times longer than II–III together. Sternites I-IV subequal in length, sternite V 1 /3 longer than sternite IV, narrowed to apex. Apex of urotergite V strongly emarginate; urosternite V emarginate, with lateral margins projecting.

Female. Antennomeres IV-V without tooth at apex. Ventrally without dense pubescence. Apex of urotergite V truncate, slightly emarginate at middle; apex of urosternite V with apical margin semicircularly emarginated, angles produced.

Measurements, in mm. male/female. n= 1/2.Total length, 10.1/10.2-10.3; prothorax length, 1.7/1.7; prothorax width at its widest point, 2.6/2.6-2.7; elytral length, 7.3/7.5-7.6; humeral width, 3.5/3.6.

Etymology. Latin, “ dentatus ” means toothed, refers to males with inner tooth in the extremity of antennomeres IV-V.

Type material. Holotype male, BOLIVIA, La Paz Department: Tumupasa, XII.1921, W.M. Mann leg. – Mulford Biol. Exp. ( USNM). Paratypes: same data as holotype, 2 females ( MNRJ, USNM).

Remarks. Neoeutrypanus dentatus sp. nov. is very similar to N. maculatus Monné, 1985 in the pattern of pubescence and in the lateral carina of the elytra restricted to the basal half. It differs in having the prothorax armed with rounded lateral tubercles situated at the posterior third; in males, antennomeres IV-V are armed with a small tooth on the inner face of the apex; the posterior apex of the pro- and mesosternal process, median region of metasternum, coxae and first urosternite are covered by dense yellow pubescence; the apices of the elytra are projected and tergite five of the female is truncate. In N. maculatus the lateral tubercles of the prothorax are acute; the males do not have a tooth at the apex of antennomeres IV-V, lack dense pubescence ventrally; the apices of the elytra are unarmed, and females have the apex of urotergite five acute and gradually narrowed.
