Species Ctenotrachelus shermani

Ctenotrachelus shermani Barber 1930

11-12 mm (NCSU Insect Museum--dead link)

Quoting from Hoffman (2):

Ctenotrachelus shermani is easily distinguished from species of other regional genera (Oncocephalus, Narvesus, Pygolampis, Stenopoda) of Stenopodainae by the antennal and femoral characters used in Blatchley’s key, but is further set off by the wide separation of the 1st and 2nd pairs of legs and a curious modification of the procoxal acetabulum. The ventral edges of propleura and mesopleura – in the region of their commisure – are flared outward to form a hoodlike covering over the coxal base...

Hoffman (2) gives range as Southeastern US (coastal plain): VA-FL-AL; recent records farther west: Louisiana; Houston, Texas area: BugGuide, iNaturalist

Asquith (3) gives range as "throughout the Gulf Coastal Plain from the southeastern United States to southern Mexico, and Cuba." That source cites specimens from Arkansas and Mississippi, as well as other southeastern states as noted by Hoffman.

Type specimen is from Raleigh, NC, and was originally under the incorrect name Schumannia mexicana Champion (2), and this record was listed that way by Brimley (4) with a date of 28 June 1902.
