Type locality: Africa: Belgian Congo: Aba, Uelle Region
|Types||Holotype: AMNH 10674|
|Diagnosis||Diagnosis: Habitus as in Ichnotropis capensis, to which it is closely allied. Hind leg not reaching axilla; head shields very rugose; frontonasd undivided; an occipital; a supraloreal between the frontonasal and the anterior loreal; an auricular shield. Anterior border of frontal square (Schmidt 1919: 508).|
Description: Habitus lacertiform; body slender; legs short; tail .56 of the total length (.57 in capensis). Head shields very rugose, except nasals and anterior loreals, about as in squamulosa, more so than in maerolepidota. Rostra1 nearly as high as wide, five-sided, pointed above, narrowly separated from the Irontonasal by the superior nasals. Nostril circumscribed by three nasals, an anterosuperior, an inferior, and a very small posterior, the latter much smaller than observed in macrolepido!a and squamulosa. A smooth supraloreal between the two upper nasals, the frontonasal, prefrontal, anterior and posterior loreals. Frontal four-sided, with two longitudinal keels, anteriorly enclosed between the prefrontals. Four supraoculars; four supraciliaries, of which the anterior exceeds the other three, separated from the supraoculars by a series of granular scales. Frontoparietals slightly exceeded by the interparietal, which is bordered behind by an occipital. Parietal shields rounded behind, with three enlarged scales on each side. Temporals small, uniform, keeled. A curved auricular bordering the ear opening anteriorly; auricular larger than in squamulosn or macrolepidota examined. Labials 8-7, above and below, four anterior to the subocular (which borders the lip) on one side, five on the other.
Dorsal scales strongly keeled and imbricate, in twenty-five longitudinal and fifty-five transverse series. Ventrals smooth, imbricate, in ten fairly regular longitudinal series and thirty cross-rows to the arms. Twenty-three scales from brachial region to the gular symphysis. Scales of the preanal area small. Fold anterior to the shoulder faint (Schmidt 1919: 508).
Coloration: General color grayish brown above. A lateral white stripe originating on the subocular, outlined above and below with black, passes above the arm, but does not reach the hind leg. A very faint dorsolateral line above this (visible only when in alcohol). Between these lines on the sides is a series of transverse black spots, two or three scales wide and half a scale long, on the tips of scales; two series of similar transverse markings dorsally, one on each side of the median line, extending to the longitudinal dorsolateral stripe. Ventral scales and chin shields white, outlined with gray, the two outer rows of ventrals punctate with brown dots. Lower and upper labials mottled with light and dark. Limbs grayish brow above, light beneath (Schmidt 1919: 510).
