description
(Figure 4 A – G) 1894 Bairdia decipiens M ̹ ller: 269, Pl. 13, fig. 29, Pl. 14, figs. 10, 21 – 22.
description
Dimensions: Female specimen 170 F, LVL 1.304, LVH 0.826 mm, RVL 1.245 mm, RVH 0.746 mm. M ̹ ller reported the range of lengths as 1.18 to 1.25 mm. Supplemental Description: The plate is broad and wedge-shaped with gently bowed lateral edges and flared anterior base. The posterior margin carries six broad, multicuspate teeth with mound-shaped to asymmetrically conical terminations, arranged three on each side of a narrow medial gap. The middle tooth is narrower than the first and third. The lateral gap is only slightly wider than the medial gap. The corner teeth are large and multi-lobed. A thick brown stripe or layer runs through the posterior edge of the plate, crossing each of the teeth at its base.
discussion
Remarks: The identification of this single female specimen is based on M ̹ ller’s description of the carapace pigmentation and patch pattern. Several species of Neonesidea in the Bay of Naples have similar H / L proportions and marginal denticulation, and their variability has not been analyzed. Bonaduce et al. (1976) lumped the occurrences of up to five of M ̹ ller’s species under one name, because of the difficulty of distinguishing them on carapace characters alone. M ̹ ller (1894, Pl. 14, figs. 33, 34) illustrated a similarly scalloped esophageal plate for an unidentified species of “ Bairdia. ”
