| Reproduction | oviparous |
| Types | Holotype: SMF 43248 (Senckenberg Forschungsinstitut und Naturmuseum), juvenile male collected August 1951 by A Zilch. |
| Diagnosis | Diagnosis: Geophis fulvoguttatus can be distinguished from G. damiani and G. hoffmanni by having 17 dorsal scale rows (15 dorsal scale rows in the aforementioned species). Of the remaining species with 17 dorsal scale rows (G. dunni, G. nephodrymus, and G. rhodogaster), G. fulvoguttatus can be distinguished from G. dunni by having smooth dorsal scales, six or seven infralabials, and a dark brown or gray dorsal coloration with irregular red or yellow dorsal blotches (dorsal scales strongly keeled, eight infralabials, and pale yellow dorsal color with dark brown saddles in G. dunni); from G. nephodrymus by having 135–157 ventral scales and segmental counts ranging from 171–181 (120–138 ventral scales and segmental counts ranging from 149–160 in G. nephodrymus); and from G. rhodogaster by having a supraocular on at least one side and the frontal not entering the orbit (no supraoculars, frontal entering the orbit on both sides in G. rhodogaster). |
