Cleodoxus tetralophus sp. nov.

( Fig. 4 )

Description. Female. Form stout, moderately robust, slightly depressed dorsally; integument dark brownish to pitchy; pubescence short, appressed, ashy. Elytra with large rounded patch of dark-brown pubescence in distal half. Lower eye lobes subequal to height of genae; upper eye lobes separated on vertex by width of lobe. Antennae surpassing elytral apices by about three antennomeres, scape not dilated at apical extremity.

Prothorax with obtuse tubercle slightly post-median; pronotum with obtuse tubercles, one in middle of the basal half and another on each side of anterior half; punctuation of pronotum restricted to basal row of punctures. Prosternal process narrowed in middle, width equal to 1/3 that of procoxal cavity. Mesosternal process equal to 1/2 width of mesocoxal cavity. Elytra parallel from base to apical fourth, extremities obliquely truncated, outer angle acute, not projected in spine. Humeri rounded, projected anteriorly. Elytral surface with two elevated ridges, basal ridge more elevated and elongated than median; lateral carina well developed, from base to apex, sides and distal third with minute granular protuberances. Legs stout, femora moderately clavate. Metatarsomere I as long II–III together.

Apex of urotergite V truncate; urosternite V narrowing to extremity, distal margin subacute.

Measurements (mm), female. Total length, 12.7; prothorax length, 2.1; prothorax width, 3.2; elytral length, 10.2; humeral width, 5.2.

Etymology. The specific epithet refers to the presence of four ridges on the elytral surface.

Type material. Holotype. Female, Bolivia, Yungas del Palmar , 4.I.1946, Coll. H. Zellibor ( MNRJ) . Paratype, Bolivia, Chaco, female. ( MNRJ) .

Comments. Cleodoxus tetralophus sp. nov. ( Fig. 4 ) differs from Cleodoxus carinatus (White, 1855) in having the prothorax with a slightly post-median obtuse tubercle, each elytron with two longitudinal ridges, numerous granular protuberances in the apical third and on the sides of the elytra, and apices obliquely truncated with outer angle not projected in a spine. C. carinatus has the prothorax with an acute median tubercle, each elytron with a single centro-basal ridge, the sides and distal third of the elytra without granules, and the apices truncated semicircularly with the outer angle projected in an acute spine.
