The specific name is from the Latin 'albo' meaning white and 'marginatus' meaning edged or bordered.
This species is known only from the type locality, Mauda (Uele), in north-eastern Democratic Republic of Congo (Pickersgill, 2004).
Aspect is raniform. A conical papilla is present in the middle of the tongue and is clearly visible. Head is as long as broad; the snout is largely rounded and as long as the length of the eye. Canthus rostralis is slightly angular; frenal region is slightly concave. Nostrils are closer to the tip of the snout than the eye. Interorbital space is slightly broader than the upper eyelid. Tympanum is distinct, measuring two-thirds the diameter of the eye. First finger is shorter than the second; the third is 1.5 times as long as the second. Fingers are slightly dilated into distinct discs. Toes are two-thirds webbed and dilated at their ends into small but quite distinct discs. Subarticular tubercles are moderately prominent. The inner metatarsal tubercle is oval shaped and well developed; the outermetatarsal tubercle is oval in shape and well-developed. A small, rather indistinct, tubercle is present on the inner side of the tarsus in the form of a fold. The inner metatarsal tubercle is located at longer distance from the tarsal tubercle than the external metatarsal tubercle. (Note: B. Zimkus examined the very poorly preserved type specimen and found that a prominent inner metatarsal tubercle and tarsal fold were present but an outer metatarsal tubercle was not obvious.) When the rear limb is brought forward, the tibio-tarsal articulation reaches beyond the eye. The tibia is 1 and 1/2 times in the snout-vent length; the width of the tibia is approximately 1/5 its length. When the hind limbs are folded up in right angles with the center of the body, the tibiae overlap. Dorsal and ventral skin is smooth. A cutaneous fold is present, leaving behind eye and extending until the insertion of the forelimb (de Witte, 1933).
Dorsum is clear brown clearly. A broad, white with rather irregular contour is present, starting behind the eyes and extending until the insertion of the hind limbs. The cutaneous fold that extends from behind eye and to the insertion of the forelimb is dark brown. The inner sides of the thighs and tibiae and below the tarsi and metatarsi are brown dark.The venter is whitish and irregularly mottled with brown (de Witte, 1933).
According to de Witte (1933), the holotype measured 30 mm in snout-vent length; Zimkus (unpublished) found this specimen to be 26.6 mm.
The IUCN Red List (2010) categorizes this species as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements (Pickersgill, 2004).
It has not been recorded in any protected areas (Pickersgill, 2004).
