Hylocurus incognitus Atkinson, sp. nov. http://zoobank.org/ urn:lsid:zoobank.org:act: 2C81AD64-4354-4308-8FA4-2DC81544F67A Fig. 5 (A–D) Diagnosis. As is the case in many species, males have a complete ring of elevated tubercles at the base of the declivity which distinguishes it from most species in the southeastern United States. Males differ from those of all known species of the genus by the presence of a pair of large, rounded tubercles in the center of the declivital face, somewhat displaced laterally from the suture. Male. Length pronotum: 1.04 mm; length elytra: 1.32 mm; total length: 2.36 mm; maximum width: 0.98 mm; length / width: 2.41 (n=3). Frons flattened, reticulate, with scattered low tubercles, vestiture inconspicuous. A faint longitudinal impression from center of frons to epistoma. Epistomal margin smooth in central ¼, sparse tufts of setae along margin to either side to antennal bases. Antennal scape short, about twice as wide as long, with sparse, short setae, each less than length of scape. Funicle about ½ length of scape. Flagellum with five segments. Club rounded, basal portion corneous; two procurved sutures on club face, marked with rows of setae. Pronotum with summit slightly anterior to middle, weakly impressed behind, with sparse, short, forwardoriented setae behind summit. Entire surface reticulate. Anterior margin elevated, irregular, weakly serrate; anterior slope with low, flattened asperities, twice as wide as long, separated by their width, closer and smaller near summit. Disc with closely spaced, low, curved elevations; punctures not evident. Elytral disc with striae strongly impressed, punctures nearly confluent; striae slightly narrower than interstriae; striae 1–3 most impressed, less so laterally. Interstriae rounded, with short, uniseriate setae associated with deep punctures; length of setae subequal to interstrial width; granules not present. All interstriae with rounded projections at base of declivity, all in line as seen from above, forming a ...
