Female paralectotype of Dipsas ellipsifera (BMNH ;488 mm SVL). condition and has a color pattern and gen- eral characteristics typical of all specimens of Dipsas ellipsifera examined. In addition to details reported for the lectotype in Ta- ble 2, it is worth noting that the dorsal formula of 16-15-15 is a variation occa- sionally observed within Dipsas. The lec- totype has a relatively longer tail (27% of total length) than other specimens of D. ellipsifera examined. Comments concern- ing the color patterns of the syntypes are given in the section on coloration below. Diagnosis Dipsas ellipsifera is characterized by a low number of ventrals (153—164 in seven males, 157—158 in two females) and sub- caudals (72—78 in males, 62—63 in fe- males). Its color pattern consists of 30 to 40 markings, each of which has a charac- teristic composition. Each marking typi- cally appears as a closely spaced pair of black bars or bands with a central whitish area (Figs. 2—5, 7); edges of the markings are more or less vertical. The markings may be continuous across the vertebral re- gion, forming complete bands, or contra- lateral markings may fail to meet in the vertebral region, forming a series of lateral bars. The anterior five or six markings are broader than more posterior ones and are Figure 4. Dipsas ellipsifera (Boulenger).

Dipsas ellipsifera differs from all other species of Dipsas in western Ecuador by its low number of ventrals and subcaudals and additionally differs from all species ex- cept D. elegans in color pattern (see Table 1 and the key accompanying this report).
