Narberdia aridulus Burke 1976: 543 . O̓ Brien & Wibmer 1982: 111. Alonso-Zarazaga & Lyal 1999: 75. Anderson 2002: 737. Soto-Hernández et al. 2013: 42.

Recognition. Male. Body oblong, length 2.7—4.1 mm; width 1.4—2.1 mm. Rostrum slender, slightly curved, 1.5— 2.1 mm, longer than pronotum along dorsal midline. Antennal scape shorter than length funicular segments and club combined; funicular segment 1 strongly clavate, subiqual in length to 2. Club elongate—oval, as long as length preceding four funicular segments combined. Eyes small with upper edge strongly separated from head. Elytra with intervals 1, 3, 5, 7 and 9 slightly wider than other intervals. Mesocoxae separated by distance about ½ width of coxa. Ventrite 5 shorter than 4. Femur with small, triangular tooth; metatibal mucro straight, acute. Male median lobe with subparallel—sided from base to apical 1/5, then narrowed to rounded apex.

Host plant. Bernardia myricifolia (Scheele) S. Watson and B. obovata I. M. Johnst.

Distribution. United States of America (Texas) and México (Nuevo León).

Remarks. Narberdia aridulus appears to be closely related to N. sarukhani , from which it differs by having elytral intervals 1, 3, 5, 7 wider than other intervals, first funicular segment subequal in length to second segment, antennal club oval, more compact, as long as preceding four funicular segments combined, femur with small, triangular tooth, not curvet toward tibiae, and male median lobe subparallel—sided from base to apical 1/5 then rounded to apex.
