Mantelliana speculum

description: Mantelliana speculum sp. nov.
Fig. 4A–C
2022 Mantelliana sp. —Araripe et al., p. 7, fig. 5 (9a–b).
Etymology: Speculum (lat.) due to the symmetry between the front and back ends that are reflected like a mirror.
Holotype: Adult shell, Nº. DGEO-CTG-UFPE-1514 (Fig. 4A), Illustrated material from the Santo Antônio section 0.3 m.
Paratypes: Adult shell, Nº. DGEO-CTG-UFPE-1515 (Fig. 4B) and Nº. DGEO-CTG-UFPE-1516 (Fig. 4C), Illustrated material from the Santo Antônio section 3.1 and 2.65 m respectively.
Type locality: Brazil, State of Pernambuco, Municipality of Exu, Santo Antônio section. Coordinates 7° 30’ 06” S and 39° 32’ 36” W.
Type-horizon: Santo Antônio section, Araripe Basin. Calcarenite (F-Sl) corresponding to the Romualdo Formation, depth 0.30 m, dated as upper Aptian.
Dimension. Nº. DGEO-CTG-UFPE-1514 (Fig. 4B); L= (LV) 0.870 / (RV) 0.976 mm, H= 0.623 and W= 0.443 mm.
Diagnosis: Carapace large, triangular, inflated and perfectly symmetrical between both ends.
Description: Carapace large, triangular outline in lateral view. Ventral margin straight. Dorsal margin with a well-marked median angularity that coincides with the greatest height. Perfectly rounded margin. Maximum length in VM. Greatest height in the median region coinciding with the location of the cardinal angle. LV larger than VR with characteristic overlaps in the ventral, posterodorsal and anterodorsal regions. In dorsal view, greatest width in the median region. Smooth surface.
Observations. Mantelliana speculum sp. nov. was compared with the female specimen of Mantelliana wealdensis (Jones, 1888) described and illustrated by Anderson, (1985). However, the well-marked angle in the dorsal region described by Anderson (1985) is not centralized, thus not dividing the valves into two practically identical parts as in the new species.
Occurrence and associated fauna. It was recorded in the Santo Antonio section, at the following depths (from base to top): 0.3; 2.25; 3.1; 3.55; 3.65; 3.85; 4.05; 5.25; 5.35; 5.55 and 5.65 m. Mantelliana speculum sp. nov. occurs associated with all species of ostracods.
Stratigraphic distribution. Brazil, Araripe Basin, Romualdo Formation, upper Aptian.

Perissocytheridea

description: Genus Perissocytheridea Stephenson, 1938
Type species: Perissocytheridea matsoni Stephenson, 1938
Remarks: Specimens attributed to the genus Perissocytheridea found in Cretaceous strata have been reported by several authors (Swain & Brown, 1964; Piovesan et al. 2014a, b; Piovesan et al. 2015; Trabelsi et al. 2021). Nogueira & Ramos (2016), showed the distribution of Perissocytheridea over geological time according to the global record and emphasized the need for studies that prove the relationship between species attributed to the Cretaceous and species found in the present. Specimens analyzed in the present study were attributed to this genus since the morphological characteristics related to the carapace are similar, that is, they have small and fragile carapaces, are subpiriform, with a straight but angled dorsal margin, have a slightly convex ventral margin, a broadly rounded anterior margin, a posterior margin presenting a posterodorsal caudal process, and a reticular surface (with pits and ridges), but are sometimes smooth. The ocular tubercle is small but visible.

description: Microceratina retangularis sp. nov.
Fig. 5J–L
2022 Microceratina sp. —Araripe et al., p 7, fig. 5 (5a–b).
Etymology: Retangularis (lat.) in reference to the carapace outline.
Holotype: Adult carapace, Nº. DGEO-CTG-UFPE-1525 (Fig. 5J–L).
Type locality: Brazil, State of Pernambuco, Municipality of Exu, Santo Antônio section. Coordinates 7° 30’ 06” S and 39° 32’ 36” W.
Type horizon: Santo Antônio section, Araripe Basin. Calcarenite (F-Sl) corresponds to the Romualdo Formation, depth 3.10 m, dated as upper Aptian.
Dimension. Nº. DGEO-CTG-UFPE-1525 (Fig. 5J–L); L= (LV) 0.353 / (RV) 0.335 mm, H= 0.223 mm, and W= 0.191 mm.
Diagnosis: Carapace small and rectangular. It has reticular ornamentation and a ventral posterolateral projection.
Description: Carapace very small. Rectangular outline in the lateral view. Ventral margin rectilinear and parallel. Dorsal margin rectilinear, descends slightly towards the posterior. Anterior margin sub-rectangular. Posterior margin rounded, truncated at ventral margin by small winged process, greater mid-length. Greatest height along the anterior margin. Left valve slightly overlaps right valve in the posterodorsal margin. In the dorsal view, valves are narrow, with the posterior margin subtly wider, ends sharp and short. Surface ornamented with smooth primary reticulations. Winged process at the posteroventral margin.
Observations. Small species, easy to recognize as it presents a rectangular shape. The main difference with the genus Perissocytheridea studied in the present work is the non-occurrence of a caudal process.
Occurrence and associated fauna. It was recorded in the Santo Antonio section, at the following depths (from base to top): 2.65 and 3.4 m. Microceratina retangularis n. sp. does not occur with Alicenula cf. leguminella, Theriosynoecum cf. quadrinodosum and Dicrorygma (Orthorygma?) dimorpha.

Illustrated material. Adult carapace, Nº. DGEO-CTG-UFPE-1524 (Fig. 5 G–I)
Dimension. Nº. DGEO-CTG-UFPE-1524 (Fig. 5 G–I); L= (LV) 0.426 / (RV) 0.396 mm, H= 0.233 mm, and W= 0.213 mm.
Comparison. It was not possible to compare with reference collection materials. Dicrorygma (Orthorygma?) dimorpha was compared to illustrations in Michael Weiss (1996); both species are very small, with a smooth surface and subtriangular carapace. The posterior end is sharp, joining the small caudal process in lateral view. The dorsal view is very similar, but the caudal process is smaller in the specimen found. We also compared the species studied with the illustrations of the species Parataxodonta inornate Kaye 1965, but they are different in the dorsal view.
Occurrence and associated fauna. It was recorded in the Santo Antônio section, exclusively at following depth (from base to top) of 5.65 m. Dicrorygma (Orthorygma?) dimorpha occurs with D. grandiensis and Dicrorygma cf. minuta, which occurs throughout most of the section.
Observations. Dicrorygma (Orthorygma?) dimorpha and Dicrorygma cf. minuta comprise the first record of this genus in the Araripe Basin (Aptian). Weiss (1996), characterized the sexual dimorphism for this species, and the specimen found is similar to the male described by this author. It is worth pointing out that it is a very small species, and like the species belonging to the genus Perissocytheridea Stephenson, 1938, they are only recovered in the smallest sieves and in the sorting process in the finest granulometry, thus requiring greater attention and persistence to recover.
Stratigraphic distribution. NW-German Kimmeridgian, Upper section (sample 5/7a), Lower Kimmeridge (ostracod-zone 10, Kimmeridgian) (Babinot et al. 2007). Brazil, Araripe Basin, Romualdo Formation, upper Aptian (this work).

Illustrated material. Adult shells, Nº. DGEO-CTG-UFPE-1522 (Fig. 5D and E) and Nº. DGEO-CTG-UFPE-1523 (Fig. 5F). Illustrated material from the Santo Antonio section (3.10 and 0.3 m, respectively).
Dimension. Nº. DGEO-CTG-UFPE-1522 (Fig. 5D–E); L= (LV) 0.321 mm and H= 0.194 mm. Nº. DGEO- CTG-UFPE-1523 (Fig. 5F); L= (RV) 0.315 mm and W= 0.174 mm.
Comparison. It was not possible to compare with reference collection materials. Dicrorygma cf. minuta was compared to illustrations in Babinot et al. (2007); both specimens are very small, with a smooth surface, and a small caudal process in lateral view. It was not possible to compare the dorsal views, so we used confer. We also compared the studied specimens with the illustrations of Dicrorygma (Orthorygma?) dimorpha Weiss, 1996; it was observed that this species is longer and larger than D. cf. minuta in dorsal view.
Occurrence and associated fauna. It was recorded in the Santo Antonio section, at the following depths (from base to top): 0.3; 2.1; 2.25; 3.1; 3.4; 3.45; 3.55; 3.65; 5.25; 5.35; 5.45; 5.55 and 5.65 m. Occurring with all species except Dicrorygma (Orthorygma?) dimorpha.
Observations. Dicrorygma cf. minuta was compared to Perissocytheridea species found in this study. The main difference is that D. cf. minuta has a smooth surface without any trace of reticulation or punctuation. In addition, it occurs abundantly along the profile, unlike the species belonging to the genus Perissocytheridea.
Stratigraphic distribution. Brazil, Araripe Basin, Romualdo Formation, upper Aptian.

description: Genus Notoplax H. Adams, 1861
Type species. Cryptoplax (Notoplax) speciosa H. Adams, 1861, by monotypy.
Diagnosis. Medium to large chitons. Tegmentum reduced, with well defined, narrow jugum; lateral and pleural areas separated by larger pustules on diagonal line. Articulamentum large; sutural laminae convex in antero-lateral edge in tail valve; insertion plates large on all valves; slit formula 5/1/3-10. Girdle large, thick, very fleshy, densely spiculose, completely (rarely almost completely) encroaching between valves; sutural tufts always present, but usually not prominent (after Gowlett-Holmes 1991, with modification). Radula teeth arranged in skewed rows; central tooth asymmetrical, large, rectangular, concave in the distal half, bilobed at base; first lateral (centro-lateral) tooth with thin, weakly notched antero-dorsal corner; major lateral tooth with long median denticle in large tricuspid head (after Saito 2004 with modification).

description: Genus Leptoplax (Carpenter MS) Dall, 1882
Type species. Chiton coarctatus Sowerby, 1841, by monotypy.
Diagnosis. Medium chitons. Tegmentum rather wide to reduced, with well defined, narrow to wedge-shaped jugum; lateral and pleural areas hardly separable (occasionally separable with larger pustules on diagonal line). Articulamentum large; sutural laminae concave in antero-lateral edge in tail valve; insertion plates medium to large on all valves; slit formula 5/1/3-10. Girdle large, thick, fleshy, densely spiculose, usually not completely encroaching between valves; sutural tufts always present, but usually not prominent. Radula teeth arranged symmetrically (rarely asymmetrical in central part); central tooth asymmetrical, spatula-shaped or those with wide basal portion, concave in the distal half, keeled at base; first lateral (centro-lateral) tooth of radula with thin or slightly thickened antero-dorsal corner; median denticle of tricuspid major lateral tooth long, but not as long as in Notoplax (radula characters: after Saito, 2004 with modification).
Remarks. The genus Leptoplax had been considered to represent a synonym of the genus Notoplax but has been reinstated by Gowlett-Holmes (2001) after redefinition of the latter genus (Gowlett-Holmes 1991), although the redefinition of Leptoplax has not been given to date. Here we propose a new definition. The main criteria to distinguish the two genera are the morphology of the sutural laminae of the tail valve and the radula, especially of the central and the first lateral teeth. However, further research including molecular analysis is needed to establish better definition for both genera.

“ Notoplax ” sp. cf. richardi: Saito, 1998: 158 –160, fig. 8.
Type material. Holotype, MNHN-IM-2000-6111.
Type locality. Capel Bank, Coral Sea, 25°20´S, 159°44´E, 56 m.
Material examined. Southern Vietnam, Cau Id., 11°13.322´N, 108°49.866´E, 12–13 m, SCUBA, sand, tail valve, 14.05.2013, leg. B. Sirenko.
Distribution. Coral Sea; Southern Vietnam; Goto Islands, Japan, 6– 56 m.
Remarks. The tail valve (Fig. 16) which is the only known specimen of this species collected during the survey of collected sand is identifiable to Notoplax richardi Kaas, 1990 [= Leptoplax richardi (Kaas, 1990) n. comb.] described from Coral Sea, at the depth of 56 m by the outline of tegmentum, wavy margins of the jugum which has oblique sulci and 2–7 micraesthete pores distributed in the proximal half of the pustule.
The generic assignment of this species is changed from Notoplax to Leptoplax herein, based on the diagnostic features of the sutural laminae of the tail valve and the central part of the radula. The latter is shown in Saito (1998: 159, Fig. 8 A). This is the first record of this species from Vietnamese waters.
