Most closely resembling U. nigricaudus but differs in having a longer tail; 3-5 enlarged supraocular scales (mean 4.1); 86-102 (mean 94) middorsal scale rows from posterior edge of interparietal scale to vent; and a less distinct dorsal pattern consisting of 5-7 (mean 5.7) dorsolateral bars.” (RAU & LOOMIS 1977)
