Descriptive Notes. Pronotum suboval with basal impressions usually deep, punctate. Elytra moderately iridescent, microsculpture striate to obsolete. Dimorphism + ♂ 2 + ♀ 2. Median lobe with dorsoapical plate subquadrate, abruptly truncated, apex slightly swollen from transverse lip dorsally and ventrally. Endophallus with bilateral rows of large spines numbered 5 + 2 on right and 4 + 2 on left with a gap before the distal 2 spines in each row (right distal 2 spines missing in one individual). ABL 6.0– 7.5 mm.

Remarks. Bousquet (2012) reported the geographic range of Selenophorus elongatus (LeConte) as AL, FL, GA. Casey (1914: 156) compared it to S. hylacis and suggested that this “very rare” species has a narrower body, pronotum slightly more elongate and with midline stria abbreviated to absent. In examining vast southeastern material, we were unable to find a convincing specimen that resembled S. hylacis with these subtle differences. The type specimen of S. elongatus imaged at mczbase.mcz.harvard.edu/guid/MCZ:Ent:5883 shows no substantial external difference from the variation we observed in S. hylacis . Selenophorus elongatus is best regarded as a synonym of S. hylacis .
