Descriptive Notes. Pronotum with anterior angles moderately projected; hind angles relatively flat, apices rounded. Elytra with seriate punctures prominent but not foveate; microsculpture cells 1:1–2:1. Legs yellowish to reddish-brown. Dimorphism + ♂ 1 — ♀ 1. Median lobe with dorsoapical plate sides subparallel; large swollen apex markedly sloped dorsally. Endophallus unarmed. ABL 4.7–6.0 mm. See S. ellipticus for additional distinguishing characters.

Range. USA: AL, CT, FL, GA, IA, IL, IN, MA, MD, MI*, MS, NC, NJ,?NM, NY, RI, TN*, TX, VA, WI*; Mexico.

Remarks. Synonymy of Celiamorphus adjunctus with S. granarius is based on our study of photographs taken of the dorsal habitus and card-mounted aedeagus of one type specimen held in the Casey collection (USNM) labeled “Galveston” [Galveston County in southeastern Texas]. The median lobe showed the diagnostic swollen apex strongly sloped dorsad.

Celiamorphus subtropicus is known only from the type series in “Texas and northern Mexico ”. We treat it as a synonym of S. granarius based on only subtle external differences described by Casey and our failure to find convincing examples among vast Texas material available to us. Photographs of a type specimen in the Casey collection ( USNM) provided support for our conclusion. The aedeagus was not examined .

Our examination of the two male syntypes (USNM #47877) of Celiamorphus nanulus [collector “Manee” = A. H. Manee, type locality in Southern Pines, North Carolina] established synonymy with S. granarius . An aedeagus glued to one of the card points exhibited the distinctive swollen and sloped apex. Their measured ABL range 4.8–4.9 mm is longer than the range “ 4.4–4.6 mm ” reported by Casey. Three typical examples of S. granarius , with dissected aedeagi in two, are held in WIRC also bearing the labels “Southern Pines, A.H. Manee, NC, V-4-1914 ”. Their ABL range measured 5.0– 5.5 mm. Populations of S. granarius with small body size are not limited to the type locality, as four examples from Newton County, Indiana (FSCA) measured 4.7–5.5 mm.
