Tijdschriftbijdrage - Tijdschriftartikel

We describe a new species of Anomaloglossus from the Pakaraima Mountains of Guyana. Anomaloglossus megacephalus sp. nov. is currently known from Maringma Tepui at 1060 m elevation and from Mt. Ayanganna at 1490 m elevation. The new species can be distinguished from all known congeners by the following combination of characters: relatively large size (females up to 28.3 mm), head large, Finger I subequal or shorter than II, the tip of Finger IV surpassing the base of the distal tubercle on Finger III when fingers are adpressed, fingers with preaxial keel-like lateral folds, best developed on Fingers II and III, toes moderately webbed with folded flaplike fringing, symmetrical cloacal tubercles present, dorsolateral stripe absent, ventrolateral stripe present, inconspicuous, oblique lateral stripe present, often broken in spots. Anomaloglossus megacephalus has been previously confused with A. tepuyensis, a taxon described from Auyantepui in Venezuela
