Diagnosis Test large, discoidal, proloculus and flexostyle followed by a planispiral stage in the microspheric generation and by a peneropline early stage in the megalospheric generation, later chambers rapidly enlarging and test becoming reniform and finally discoidal with annular chambers, chambers subdivided internally by intradermal plates that are thickest adjacent to the lateral walls, their basal part extending across the chamber to fuse with the base of the plate from the opposite side, resulting in nearly complete chamberlets, or when plates projecting from the two sides of the test alternate in position, a Y-like fusion of their bases produces a double series of chamberlets; wall calcareous, porcelaneous, surface smooth, may be punctate; aperture of one or two alternating rows of rounded openings in a groove at the periphery. Pliocene?; Pleistocene to Holocene; Puerto Rico; Dominican Republic; Cuba; USA: Florida; New Guinea. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
Taxonomic remark "Sequencing work by Holzmann et al (2001) showed that specimens from Florida Keys belonged in the Archaiasinae. These specimens were identified as Broeckina sp. but are actually Parasorites orbitlitoides from their type region - the Caribbean. In that paper Parasorites sp. was recorded from the Pacific but these are likely "Laevipeneroplis" malayensis" pers. comm. W. Renema, 2023 [details]
