Material: one specimen (stage 34), one specimen (stage 36), three specimens (stage 38), one specimen (stage 39).

Buccal floor ( Fig. 3A View FIGURE 3 ): Ovoid buccal floor, wider than long. One pair of large infralabial papillae, concave on the anterior surface, apex with elongated projections and occupying a large part of the oral cavity entrance. Infrarrostral projections are absent. Four lingual papillae, in equivalent size, the two lateral ones are bifurcated and the two median ones are digitiform (forming a " YIIY " design), rounded apex and arranged in the same transversal plane. In one specimen was observed three papillae, all bifurcated in “Y”. The BFA is delimited by nearly 40 digitiform papillae, in different size, tapered apex and nearly 90 pustules distributed between the papillae. There are no structures in the anterior region of the BFA. The buccal pockets are transversely oriented. The ventral velum is long and U-shaped; undulated and tumid margin, with a glandular appearance, constituted by secretory pits and about eight globular projections in the middle portion. Buccal roof ( Fig. 3B View FIGURE 3 ): Ovoid buccal roof, as wide as long. Prenarial arena has a low transversal ridge and irregular apex. Large choanae, elliptical and obliquely oriented; the posterior valve is high and the anterior has five prenarial papillae on the inner edge and narial valve projections are present. The distance between the choanae is equivalent to median ridge width. The postnarial arena has either four or five digitiform papillae on each side, in different size, with smooth surface, rounded apex and arranged forming an inverted " V " design. Before these papillae there are about three pustules. Median ridge is trapezoid-shaped; flattened and anterior margin irregular. The lateral ridge papillae have the apex wider than the base, flattened, with four digitiform secondary branches in different size and smooth anterior margin of the branches. The BRA is delimited laterally by five digitiform papillae on each side, elongated, in different size, tapered apex and arranged on the side. There are nearly 90 pustules evenly distributed in the middle region of the BRA. Conspicuous glandular zone, thickened in the middle portion. The dorsal velum is short; undulated margin, with the lateral fold showing a glandular appearance and elongated projections in the middle region .
