Naddia Fauvel, 1867

TYPE SPECIES: Caranistes westermanni Erichson, 1840 .

COMMENTS: Members of this genus share the following character states: ( 1) posterolateral portions of head extended posteriad as rounded lobes ( fig. 105 ); ( 2) eyes distinctly shorter than tempora, almost perfectly round to scarcely oval; ( 3) mandibles short and wide basally ( fig. 9 ) (see key for details); ( 4) width of mentum less than three times its maximum length; ( 5) lateral margins of pronotum abruptly explanate a short distance behind anterior angles, giving appearance of an indentation ( fig. 106 ); and ( 6) paramere of aedeagus somewhat dorsoventrally flexible, without sensory peg setae.

Further character states include: outer antennal segments slightly asymmetrical to subserrate; mentum with cluster of variable anterolateral setae; maxillary palpus with apical segment stoutly flattened, with last two broadening to apex; last segment of labial palpus short, fusiform, setose; mandibular prostheca lanceolate, with short ciliae along medial margin; postmandibular ridge rudimentary; postgenal ridge present only laterally; superior line of pronotal hypomeron moderately deflexed ventrad between middle of pronotum and anterior angles of pronotum, with anterior portion of superior line therefore situated only moderately below basal portion in lateral view; deflected portion of pronotal disc visible in ventral view only from edge of coxal insertion; hypomeron very broad at middle; proepimeron well developed, membranous; series of long setae on mesosternum situated on small tubercles in a very broadly U­shaped pattern (shared with members of Platydracus ); mesosternal intercoxal process with margins slightly concave, narrowly rounded apically; metasternum oblique, highly convex between coxae, horizontal posteriorly; dorsal apicolateral lobe of metacoxa with one short, fine spine.
