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).
