Palaecysta pectita subsp. pectita
Palaecysta pectita subsp. pectita
Autonym.
Holotype: Chen, 2013, pl.8, fig.91.
Original description (Chen, 2013):
Palaecysta pectita sp. nov.
Modified from pecto, Latin, comb, pectito, small comb, depicting the branching pattern of the process clusters.
Holotype. Plate 8, Figure 91 Slide 1226-35/N1, M32
Paratypes. Plate 8, Figure 89, Slide 1256-65/N1, E50; Plate 8, Figure 90, Slide 1304-07, S15; Plate 8, Figure 93, Slide 1238-41, F32; Plate 8, Figure 96, Slide 1268- 71, R7.
Other specimens. Plate 8, Figures 88, 92, 94, 97, 98.
Synonym
Systematophora areolata Klement (Durr, 1988; € Plate 7, Figures 1-2)
Systematophora cf. areolata Klement (Davey, 1987; Plate 11, Figure 14)
Systematophora cf. areolata Klement (Davey, 1982; Plate 1, Figures 5, 6)
Diagnosis: The comb-like, robust nature of the process clusters, with 4-6 processes per process cluster, is the main characteristic of this species (Figure 9, drawing 11; Figure 10, drawing 36; Figure 11, drawing 66).
Dimensions (based on measurements from 50 specimens):
Holotype – Whole specimen 95 µm; central body 69 µm; process length 31 µm
Range – Whole specimen 90 (95) 110 µm; central body 65 (70) 75 µm; process length 25 (30) 35 µm
Remarks: This species is similar to P. morondavaensis in the robust nature of the process clusters; it, differs, however, from the latter in possessing a much shorter basal ridge in the process clusters. Hystrichosphaeridium scoriaceum Raynaud (1978; Plate 1, Figure 4, 5) and Systematophora scoriacea (Raynaud) Monteil (Pavlishina & Feist-Burkhardt, 2004; Plate II, Figure 6, 7; Plate IV, Figure 4) may be conspecific with this species, but is uncertain due to the low quality of the photomicrographs in both publications.
Occurrences in the Ankamotra-1 well. P. pectita occurred most abundantly in Zone 3 (mid-Berriasian).
