Material: one specimen (stage 34), one specimen (stage 36), three specimens (stage 38), one specimen (stage 39). Buccal floor (Fig. 3 A): 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.
