Diagnosis	Diagnosis (genus). Very similar to Monopeltis, but nasal shields almost always separated by rostral segment, no precloacal pores, generally only a single cephalic shield, always a modified pectoral region, and tip of the tail always squarely truncate and produced into a flattened callous pad. Table 2 presents meristic differences for all but the northernmost populations. (Broadley et al. 1976, Modified after Vanzolini 1951)
Comment	This species is known from its type specimens only (GANS 2005). Type species: Dalophia welwitschii is the type species of the genus Dalophia (fide GANS 2005) although he lists this species as a member of the genus Monopeltis. Technically, this implies that Dalophia is a synonym of Monopeltis, but nobody has apparently done a proper phylogenetic analysis to resolve this.
Etymology	Named after Dr. Friedrich Martin Josef Welwitsch (1806-1872), an Austrian theater critic before fleeing to Portugal to escape the consequences of a youthful indiscretion.
