This is an undescribed species of treefrog, similar to and sometimes sympatric with Boophis elenae Andreone, 1993 . The following description is based on one tadpole in developmental stage 31 (ZSM uncatalogued, field number LR 214, TL 36.3, BL 14.6 mm), from locality 3.
In dorsal view ( Figure 9a View Figure 9 ), body ovoid, snout rounded. In lateral view ( Figure 9b View Figure 9 ), body depressed, BW 116% of BH, snout rounded. Eyes moderately large, ED 14% of BL, slightly bulging, not visible in ventral view, positioned dorsolaterally but directed laterally, situated at about the anterior third of the body. Nares small, oval, rimmed, positioned and directed dorsolaterally, much closer to the anterior edge of eyes than to tip of snout, RN 137% of NP; NN 58% of PP. Spiracle sinistral, moderately small, slightly conical, clearly visible from ventral view, its tip free from body; spiracular opening oval, orientated posterodorsally, much closer to end of body than to snout, SS 70% of BL and situated well below the longitudinal axis of tail musculature. Vent tube short, dextral, opening directed posterolaterally, its right wall displaced anteriorly. Caudal musculature strong, TMH 62% of both BH and MTH, TMW 51% of BW, height of caudal musculature about one-third of the total height at mid-tail, reaching tail tip. Caudal fins concave in their anterior parts, convex towards mid-tail then reducing gradually up to tail tip, MTH 100% of BH; dorsal fin originating well posterior to the dorsal tail–body junction, ventral fin starting just behind the body; tail tip pointed.
Oral disc ( Figure 9c View Figure 9 ) moderately large, ODW 31% of BL and 56% of BW, positioned anteroventrally and directed ventrally, not emarginated. A total number of 164 marginal papillae disposed in two rows around the oral disc, interrupted by a large median gap on the upper labium (DG 67% of ODW); gap on the lower labium not distinct. Submarginal papillae clustered in the corners of labia. Papillae of moderate size, elongate with more or less rounded tip. No denticulate papillae. Keratodont row formula 1:3+3/1+1:2. About 194 keratodonts on A1 (ca 54 per mm). The length of the interrupted anterior rows A2, A3, and A4 decreases towards centre of disc; P2 and P3 subequal in size, P1 slightly shorter. Both jaw sheaths serrated and fully black pigmented; upper jaw with a large medial serration surrounded by smaller serrations on each side forming a slight convexity; lower jaw Vshaped.
Coloration in preservative. Dorsally: body and tail musculature dark brown with scattered black spots; some pigmentation forming a distinctive dark patch between eyes and also on mid-dorsal area of body. Laterally: body and caudal musculature covered by scattered dark pigmentation; musculature junctions obvious in the anterior half of tail musculature; intestinal coils completely visible; fins transparent with scattered pigmentation; dorsal fin showing some reticulations. Ventrally: whole surface of ventral body transparent; branchial and cardial organs visible through translucent ventral surface.
Variation. TL and BL of six tadpoles at stages 25–41 (LR 243, LR 228, LR 230, LR 214, LR 234, LR 249), all from locality 3, are 21.2–40.0 and 8.5–15.0 mm, respectively. The ratios vary in the following proportions: BW 116–157% of BH; ED 13.9–16.5% of BL; RN 87–143% of NP; NN 42–58% of PP; SS 69–78% of BL; TMH 50–67% of BH; TMH 53– 69% of MTH; TMW 41–54% of BW; MTH 73–108% of BH; ODW 27–36% of BL; ODW 47–63% of BW. KRF of the six tadpoles varies from 1:3+3/1+1:2 to 1:5+5/1+1:2.

The following description is based on one tadpole in developmental stage 25 (ZSM 527/ 2004, field number LR 96, TL 17.5 mm, BL 6.7 mm), from locality 1.
In dorsal view ( Figure 10a View Figure 10 ), body ovoid, snout rounded. In lateral view ( Figure 10b View Figure 10 ), body greatly depressed, BW 156% of BH, snout rounded. Eyes of moderate size, ED 10.5% of BL, not visible in ventral view, positioned dorsolaterally, situated at about the anterior third of the body. Nares moderately sized, round, rimmed with a small flat mediodorsal projection, positioned quasi-dorsally and directed anterodorsolaterally, equidistant between tip of snout and anterior edge of eyes, RN 100% of NP; NN 60% of PP. Spiracle sinistral, moderately large, well visible from dorsal view, tubular, inner wall free from body; spiracular opening oval, orientated more posteriorly than posterodorsally, closer to end of body than to snout, SS 69% of BL, situated at the height of the lower part of tail musculature. Vent tube moderately sized, short, dextral, opening directed posterolaterally, its right wall displaced anteriorly, entirely linked to ventral tail fin. Caudal musculature moderately developed, TMH 44% of BH and 42% of MTH, TMW 38% of BW, its height almost half of total height at mid-length of tail. Caudal fins regular with straight edges, MTH 104% of BH; dorsal fin originating next to body–tail junction, reduced in the anterior part and convex at about half of tail length; point of maximum tail height reached towards mid-tail; ventral fin moderately shallow; tail tip roughly rounded.
Oral disc ( Figure 10c View Figure 10 ) of moderate size, ODW 25% of BL and 44% of BW, positioned and directed anteroventrally, emarginated. A single row of marginal papillae interrupted by a large median gap on the upper labium (DG 59% of ODW), and by a short gap on the lower labium; total number of marginal papillae about 48 (23 on the left side and 25 on the right side). No distinct submarginal papillae present. Papillae of moderate size, cylindrical elongate with rounded tip. No denticulate papillae. Keratodont row formula 1:3+3/1+1:2. About 58 keratodonts on A1 (55 per mm). The length of interrupted anterior keratodont rows decreases gradually towards the centre of the disc, P1 and P2 subequal in length, P3 shorter. Jaw sheaths moderately coarsely serrated; upper jaw as a large arch with a median convexity, totally coloured by black pigment; lower jaw V-shaped.
Coloration in preservative. Dorsally: body and tail musculature generally brownish, uniformly pigmented by black dots. Laterally: intestinal coils partially visible on the lower part of the body; dorsal fin faintly pigmented on the anterior part near its starting point; ventral fin clear; body and caudal musculature with black dots. Ventrally: region of the branchial and cardial organs somewhat obscure but still visible through the ventral surface of the body.
Variation. TL and BL of eight tadpoles at stage 25 (ZSM 527–532, LR 96c, LR 96f), all from locality 1, are 13.5–20.0 and 5.5–7.3 mm, respectively. The ratios vary in the following proportions: BW 113–156% of BH; ED 0.9–11.0% of BL; RN 60–120% of NP; NN 57–66% of PP; SS 60–73% of BL; TMH 41–59% of BH; TMH 34–54% of MTH; TMW 31–39% of BW; MTH 97–128% of BH; ODW 20–25% of BL; ODW 35–45% of BW. KRF of the eight tadpoles is 1:3+3/1+1:2.
