|Diagnosis||Diagnosis. “A member of the nigricaudus complex (Mittleman, 1942: 162) possessing an entire frontal, a band of enlarged dorsals which are not separated into parallel series by the presence of smaller vertebral scales. 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)|
Comparisons. “Urosaurus lahtelai is separated from U. microscutatus by the band of enlarged middorsal scales and a longer tail. It is separated from U. graciosus by the single frontal scale, fewer supraoculars and other characteristics given in Table 1 . It differs from all other species of Urosaurus in the arrangement and kind of enlarged dorsal scales, the lack of enlarged scales along the lateral line and the ratios of tail to snout-vent length. U. lahtelai is most similar to U. nigricaudus with the major differences being the longer tail, fewer enlarged dorsal scale rows and a less distinct dorsal pattern. Also there seems to be a degree of difference in the number and arrangement of the first row of frontonasal scales in contact with the internasals as U. lahtelai usually has 2 enlarged frontonasal scales and U. nigricaudus usually has 3 smaller frontonasal scales. Table 1 shows differences between these two species.” (RAU & LOOMIS 1977)
