TypesHolotype: INHS (= UIMNH) 25064 (23646); E. H. Taylor; July 29, 1940. 
DiagnosisDiagnosis. Similar to Ficimia publia, but blotches on body 43, on tail 11. Similar to Ficimia variegata, but internasals present. Two postoculars; blotches narrow, tending to be light-centered; ventrals 154; caudals 33 (Smith & Taylor 1941: 364).

Description of holotype. Rostral large, elongate, its suture with frontal subequal to sutures between latter and prefrontals ; rostral sharply upturned anteriorly, the ridge bordered posteriorly by a shallow depression ; length of rostral from anterior ridge to frontal (2.3 mm) distinctly greater than length of frontal (2.0 mm), very slightly greater than length of median parietal suture; nasal narrow, anterior section fused with first labial; prefrontal in contact with second labial; preocular single, large; two postoculars, lower smaller; one elongate, narrow, anterior temporal; two (three) tertiary temporals; seven supralabials, all relatively high, sixth largest, fourth next largest, third and fourth contacting orbit, seventh slightly larger than lower tertiary temporal; diameter of orbit nearly as great (five-sixths) as its distance from labial border, little less than half its distance from tip of snout; seven infralabials, fourth largest, three in contact with anterior chinshields; posterior chinshields practically indistinguishable, separated medially by two scales, somewhat larger than gular scales, in contact with two labials. Scales in 17 rows throughout, smooth, with single apical pits; ventrals 154; anal divided; caudals 33. Total length 144 mm; tail 20 mm (Smith & Taylor 1941: 364).

Color. General color light gray; body with 43 transverse, black blotches, some of the anterior blotches with dimly lighter (brown) centers; blotches broken on sides of body at about fifth scale row; below this sides with irregular black spots and vertical streaks, some rarely confluent with dorsal blotches, some involving ends of ventrals; spaces between blotches about equal to length of blotches or slightly less (one and one-half to two scale lengths, middorsal line); tail with 11 dorsal crossbars, sides with a very few spots. Top of head somewhat brownish gray, with numerous irregular black marks; a large dark spot under eye, reaching lip; labial sutures dark. Infra-labial sutures dark stippled, the markings not distinct ; no other gular marks ; some spots on sides of body involving ends of ventral ; a little scattered stippling on sides of belly; otherwise ventral surfaces unspotted, white (Smith & Taylor 1941: 364).
