Lithocampe wharanui Hollis, 1997

Description - Add description

Description: Test of up to five segments; first three comprising almost half the total length, last 1-2 segments thinner walled and often not preserved. Cephalis spherical, sparsely perforate, may be partly enclosed in thorax, rarely with a weak apical horn. Thorax large, hemispherical and approximately equal in length to the abdomen, but always narrower. Pores of thorax and abdomen small, circular with hexagonal frames, in close quincuncial arrangement consisting of six to seven transverse rows on each segment. Hemispheroidal final chamber has a small aperture, usually without a collar.
Remarks: Pores of this species are smaller and more densely distributed than in species assigned to Lithocampe by Petrushevskaya & Kozlova (1972, Petrushevskaya 1975). Some species resemble Theocapsomma amphora, but are distinguished by having a series of 2-3 post-thoracic segments rather than a single inflate abdomen. The Thorax is considerably larger than that of L. marinae Gorbovetz (Kozlova and Gorbovetz 1966, pl. 15, figs. 10, 11).
