Diparvapila MacDonald, 1998: 594 ; 2003: 114.
Parvalanapila MacDonald, 1998: 597 ; 2006b: 207.
TYPE SPECIES. — Diparvapila hicocki MacDonald, 1998 ( MacDonald 1998: 595, fig. 4.6, 4.10-4.12, 8.9-8.11).
AGE AND LOCATION OF TYPE MATERIAL. — Upper Llandovery, Cape Phillips Formation, Cornwallis Island, Arctic Canada.
TAXON CODE. — 069.
STATUS. — Valid.
DIAGNOSIS. — “Secuicollactinae with two spherical lattice shells; pentactine or hexactine spicule ectopically placed on medullary shell, one ray perpendicular to others; single primary spine unit with medullary shell gives rise to antapical spine” ( MacDonald 1998: 594).
REMARKS
In his dissertation, MacDonald (2003: 114) emends the diagnosis to include forms where the outer shell is either labyrinthine or latticed, thus including species previously split out into his genus Parvalanapila MacDonald, 1998 . The emended diagnosis was not formally published, however the type species of Parvalanapila , P. fleischerorum is considered a Diparvipila by MacDonald (2006b: 207).
