Material: Numerous subfossil specimens from Nosy Be, Madagascar. One dry female carapace containing fragments of body, from Amirante Island.
Dimensions: Female specimen 458F, from Admirante Island: LVL 0.927mm, LVH 0.596 mm. It fits at the upper lefthand edge of the scatter plot for the population from Nosy Be (Maddocks 1995, Graph 1). Hartmann (1964) reported the following measurements: Female LVL 0.95 mm, LVH 0.56 mm, RVL 0.93 mm, RVH 0.50 mm; Male: LVL 1.04 mm, LVH 0.61 mm, RVL 1.02 mm, RVH 0.57 mm. The following dimensions were reported by Maddocks (1969): Adult male USNM 121252, LVL 1.09 mm, LVH 0.57 mm, RVL 1.03 mm, RVH 0.52 mm; Adult female USNM 121253, LVL 1.096 mm, LVH 0.61, RVL 1.01 mm, RVH 0.57 mm. A length-height scatter plot for the subfossil population of Nosy Be, Madagascar, was published by Maddocks (1995, Graph 1, p. 236a).
Supplemental Description. Fig. 16A is a digital scan of a contact paper print of an over-exposed photographic negative of an over-stained dissection of specimen 13M from Nosy Be, made in 1967. In left-lateral view, it shows the compressed head capsule with upper and lower lips, atrium, esophagus, rotated EV with ring, plate, shafts of two braces, and aprons inserted against the Hs strut [see Maddocks (2018) for discussion of the gross anatomy]. The posterior margin of the plate (Fig. 16G) appears to be coarsely scalloped.
The plate of specimen 458F is narrowly fan-shaped, with nearly straight edges, undulating anteromarginal scrolls, and an irregularly scalloped posterior margin, which has broad teeth on either side of a narrow medial gap, one or two smaller teeth, and multilobate corner teeth.
The slightly damaged LV of specimen 458F is high-arched with a steep, continuously-sloping posterodorsal margin, well developed posteroventral denticle, and a well-developed row of plumose setae above the caudal angle. The posterodorsal opaque spot that is usual in N. schulzi is not visible.
Remarks: Hartmann (1964) pointed out differences of size, shape and marginal denticulation from N. longisetosa, with careful illustrations of the antennal hook, marginal denticles, plumose caudal setae and the finely crenulate (microcrystalline) texture of the hinge elements. Many of those traits have proved to be diagnostic for the genus. Maddocks (1995) clarified the taxonomic concept for the genus and some Indo-Pacific occurrence records for the species.
Distribution: On calcareous algae at Ghardaqa, common to 80 m in the Gulf of Aqaba, Red Sea; common in shallow carbonate environments around Nosy Be, Madagascar; near Anse Royale on Mahe Island, Amirante Island group, The Seychelles.
