Description. Rostrum elongate, cylindrical. Antennae geniculate
(Fig. 19); scape very long, slender; funicle with basal 4 or 5 segments
moderately slender and apical 2 segments enlarged and setose; antennal
club compact, composed of 3 or 4 closely fused segments. Eyes round,
laterally extending to dorsal surface, dorsally very close. Frons narrow.
Pronotum conical; sides tapering sharply to anterior margin; basal
margin finely elevated. Elytra widest near humeri; sides strongly and
evenly curved to broadly rounded apex; striae punctured in even rows.
Legs with middle coxae separated by intercoxal process; femur with 0-3
teeth; male tibia mucronate.
Type species. Curculio lythri Fabricius, by original designation.
Comments. Schoenherr (1838) proposed Nanophyes as a
replacement name for Nanodes Schoenherr (1825), which he erroneously
thoughtwas preoccupiedby Nanodes Stephens (1826) (Aves). According
to the International Code of Zoological Nomenclature, Nanodes is
the correct name for this group of species; however, .Llonso-Zarazaga
and Dieckman (1987) appealed to the International Commission on
ZooLogqcal Nomenclature to have Nanophyes declared the valid name.
The commission decided in 1989 to conserve Nanophyes and declared it
to be the proper name for this genus. Kissinger (1968) revised this genus
(under the name No nophyes Schoenherr) for North America and gives a
key to distinguish the North American species.

Description. Length t.2-I.6 mm. Body light reddish brown;
head and ventral surface much darker. Pubescence consisting of white,
very fine, sparse setae. Rostrum of male slightly curved in lateral view,
1.3-1.4 times longer than pronotum; sides in dorsal view evenly diverging
from base to antennal insertion, then nearly parallel to tip; surface with
moderately high, median, with dorsal carina behind antennal insertion
and with sublateral carina, lateral carina, and low, indistinct carina
representing dorsal margin of scrobe; surface finely alutaceous, with
minute shallow punctures and fine short scales. Rostrum of female
similar to that of male, but portion beyond antennal insertion polished
and with more distinct punctures. Antennae inserted at basal 0.5-0.6 of
rostnrm. Frons 0.3-0.4 times wider than tip of rostrum. Pronotum L.6-t.7
times as wide as long; sides strongly converging; surface with shallow
