Species Description: Senevirathne G, Samarawickrama VAMPK, Wijayathilaka N, Manamendra-Arachchi K, Bowatte G, Samarawickrama DRNS, and Meegaskumbura M. 2018. A new frog species from rapidly dwindling cloud forest streams of Sri Lanka—Lankanectes pera (Anura, Nyctibatrachidae). Zootaxa. 4461: 519–538.
Color in life: Dorsally chocolate brown with unequal dark-brown patches. Ridges of the numerous prominent corrugations lighter in color, with interspersed light-brown spots. A light-brown bar edged with dark brown/black colors in the interorbital area. Flank, inguinal zone, loreal region and sides of back of head light brown. Throat, margin of throat and vocal sacs white with pale brown patches. Chest, belly ventral sides white. Ventral sides of thighs light brown, with white patches. Underside of webbing light brown. Disks and tubercles of pes and manus grey-brown (Senevirathne et al., 2018).
Color in alcohol: Dorsally dark brown with unequal dark patches, edges of corrugations lighter in color, some pale spots on dorsum. A pale-yellow bar with dark edges on inter-orbital area. Flank, inguinal zone, loreal region and sides of back of head light brown, edges of corrugations pale. Throat, margin of throat and vocal sacs pale brown with lighter spots. Chest, belly, ventral sides of thighs and webbing light brown (Senevirathne et al., 2018).
Diagnosis: The genus Lankanectes is endemic to Sri Lanka and it comprises of two species, L. pera and L. corrugatus (Batuwita et al.,2019). Lankanectes pera can be distinguished from L. corrugatus by the following characters: ventrally greyish (vs white with dark brown patches in L. corrugatus); white tubercles on throat (vs smooth throat in L. corrugatus); edge of the upper lip uniform grey (vs white border with dark brown patches in L. corrugatus); inner edge of toes grey (vs inner edge of I, II, III and IV toes white in L. corrugatus); inner edge of foot grey (vs white in L. corrugatus); flank grey (vs. flank with dark brown and white patches inL. corrugatus). Molecular phylogenetic analysis revealed that the uncorrected pairwise genetic distance between L. corrugatus and L. pera is 3.5–3.7% confirming them as two distinct species (Senevirathne et al., 2018).

Etymology: Lankanectes pera is named after the University of Peradeniya, Sri Lanka, affectionately referred to as “Pera” by its alumni (Senevirathne et al., 2018).
