Parvalanapila MacDonald, 1998

Parvalanapila MacDonald, 1998: 597 .

TYPE SPECIES. — Parvalanapila fleischerorum MacDonald, 1998 ( MacDonald 1998: 599, fig. 5.8, 5.11, 9.1-9.5).

AGE AND LOCATION OF TYPE MATERIAL. — Llandoverian, Lower Silurian, Cape Phillips Formation, Cornwallis Island, Arctic Canada.

TAXON CODE. — 072.

STATUS. — Junior synonym of Diparvapila MacDonald, 1998 (by MacDonald 2006b: 207).

DIAGNOSIS. — “Secuicollactinae with single lattice shell covered by labyrinthine layer formed of interlocking apophyses arising from short spinules off lattice and from spines; spicule ectopically placed on lattice sphere; single primary unit with lattice shell, gives rise to antapical spine.” ( MacDonald 1998: 597).

REMARKS

The main difference between this genus and Diparvipila, as noted by MacDonald (1998), is the wooly versus latticed outer layer. Further observation of the type species ( MacDonald 2003), reveals a fair amount of variation in the outer layer, causing MacDonald to consider synonymous with Diparvipila. In a later publication the type species of Parvalanapila appears as Diparvapila fleischerorum ( MacDonald 2006b: 207) .
