Rana ocellata Linnaeus, 1758

Hyla brunnea Gosse, 1851 [new synonymy] Trachycephalus scutigerus Cope, 1863 [new synonymy]

Neotype: USNM 251390, adult male ( Figure 1 ), collected in Jamaica, Hanover Parish, 1.7 miles SSE of Hopewell, on 0 8 July 1977, by Ronald I. Crombie and Jeremy Jacobs.

Description of the neotype: Skin exostosed with skull from level above tympanum, extending between eyes to mid loreal region, almost reaching nares. Snout shape nearly rounded in dorsal outline, rounded in profile. Canthus rostralis distinct, almost sharp. Loreal region convex/obtuse. Tympanum distinct, about 70% eye diameter. Vomerine teeth in two short patches with about five teeth per patch, almost equidistant from each other and choanae; vomerine teeth aligned along a line drawn from the posterior extents of the elliptical, slightly transversely oriented choanae. Vocal slits present, elongate. Vocal sac single, weakly developed. Finger disk II (finger numbering following Fabrezi and Alberch 1996) rounded, smaller than large round disks on fingers III, IV, V. Finger web formula II trace III 1 ½ – 2 ¾ IV 3 ½ – 2 ½ V. Subarticular tubercles weak, single on fingers II, III, IV, bifid on V. Tan nuptial pad covering prepollical area to level of subarticular tubercle on finger II. Forearm slightly hypertrophied. Outer ulnar region with a row of few, light, fleshy tubercles. Supratympanic fold weakly developed. Anal region undecorated. Dorsal texture smooth, without folds; throat smooth; belly areolate. Toe disks round, well developed; toe disk I smaller than others; toe disks slightly smaller than finger disks. Toe web formula I trace II 1 ½ – 3– III 1 – – 3– IV 2 ¾ – 1+ V. Inner metatarsal tubercle elongate, protuberant distally. Outer metatarsal absent. Tarsal fold absent. Heels with a few indistinct fleshy tubercles.

Color: In preservative, the specimen is overall an unremarkable brown frog. Head brown with slightly darker upper eyelids. Dorsum weakly lichenous patterned (slightly darker and lighter browns). Tympanum tan with obvious dark brown spot extending from top of tympanum to just below middle of tympanum. Upper limbs brown; faintly lichenous. Throat finely mottled, slightly darker than remainder of mottled ventral surfaces.

Measurements of the neotype: SVL 49.9; HL 18.7; HW 18.4; IND 3.8; END 6.1; ED 7.7; UEW 5.0; IOD 6.7; TD 3.8; HAL 4.0; THL 20.5; TL 21.8; FL 28.8.

Nomenclature: The neotype of Rana ocellata Linnaeus, 1758 is a species up until now recognized as Osteopilus brunneus . The synonymy of Osteopilus ocellatus ( Linnaeus, 1758) contains Hyla brunnea Gosse, 1851 and Trachycephalus scutigerus Cope, 1863 .
