Emended diagnosis.—Larger than L. dubius , but overlapping with this species for smaller individuals. Morphology and intra−segment proportions otherwise similar to those in L. dubius or L. crumeniferus . Inter−segment proportions indicating probably more developed hind limbs relative to forelimbs than in extant species.

New material, localities, and age.—An incomplete left tibiotarsus from the early Pliocene of Kossom Bougoudi ( Chad), KB3−97−161, comprising part of the distal end and all the shaft ( Fig. 1A 1 –A View Fig 3 View Fig ), probably from a male; a distal part of right tibiotarsus shaft from the early Pliocene of Sagantole ( Ethiopia), SAG−VP−1/19 ( Fig. 1B 1 View Fig ), associated with a partial left tarsometatarsus, SAG−VP−1/19, comprising the distal end and most of the shaft ( Fig. 1B View Fig 2 –B View Fig 7)—these two elements are from a single individual; a left distal tibiotarsus from the late Pliocene of Omo ( Ethiopia), OMO−122−76−367 ( Fig. 1G 1 –G View Fig 3 View Fig ), and a right first pedal phalanx of digit II probably from a female, also from the late Pliocene of Omo, F−516−23 ( Fig. 2A View Fig 1 –A View Fig 3 View Fig ).

Material, localities, and age.—A proximal half of a left carpometacarpus from the late Pliocene of Koro Toro ( Chad), KT13−96−504, with part of the proximal end, and a distal half of a left carpometacarpus, KT13−98−004, with an almost complete distal end ( Fig. 2B View Fig 1 View Fig , B 2 View Fig and C 1 View Fig , C 2 View Fig )—these two elements almost certainly come from a single carpometacarpus, and the total length can be reconstructed; a right distal tibiotarsus from Urugus (early Pliocene, Ethiopia), URU−VP−1/15 ( Fig. 1F View Fig ); a left distal tibiotarsus from Urugus, URU−VP−1/28 ( Fig. 1E 1 View Fig , E 2 View Fig ); a left first pedal phalanx of digit III from Urugus, URU−VP−1/45 ( Fig. 3A View Fig 1 View Fig ), associated with a 12 th vertebra (i.e., 10 th after the atlas and axis), URU−VP−1/45 ( Fig. 3A View Fig 2 View Fig , A 3 View Fig )—these two elements are from a single individual. The 12 th vertebra URU−VP−1/45 is about 55 mm long and 45 mm wide.
