Quercus palustris, rubra, texana [buckleyi]
Stem galls, cells hidden under bark
Slight enlargement of base of the annual growth in July, containing a few larval cells just under the bark in the wood. Entered from lit.

Never reared. On Q coccinea. Also on Q imbricaria, palustris. Cell in wood just under bark. Possibly Bassettia ceropteroides.

Bassettia ceropteroides
Described from Q velutina. An inconspicuous enlargement of the annual growth containing but a few cells. Found in July. Included from literature.

Callirhytis ceropteroides n. sp.

Galls. — Slight enlargements of base of the annual growths of the shoots of tinctoria. These swellings are often so inconspicuous that it is very difficult to distinguish them from the unaffected branches. Occasionally one is so developed as to attract notice. They are polythalamous, though only a few insects are found in even the largest. Found in July at Crescent Beach, Branford, Conn.

Callirhytis ceropteroides Bassett, 1900

[transferred back from Bassettia to Callirhytis]

Biology--Only the asexual generation is known which induces stem galls on Q velutina. Adults emerge in July.

Distribution--CT, WV

Zapatella ceropteroides, new combination
[Buffington et al describe a new species, Zapatella davisae, from specimens previously identified as Callirhytis ceropteroides but found to differ from that species anatomically. They also transfer ceropteroides to genus Zapatella]

Zapatella davisae was previously identified as Callirhytis ceropteroides and it has been implicated in damaging Quercus velutina in the past. Callirhytis ceropteroides, which was transferred from Bassettia Ashmead to Callirhytis ‘sensu stricto’ (Melika & Abrahamson 2002). Specimens of this species were located in the USNM (including one paralectotype) and compared with Zapatella davisae. While clearly not the same species as Z. davisae, this species was determined to conform quite clearly to Zapatella, and may indeed be a synonym of Z. quercusmedullae. As this latter question is beyond the scope of this paper, we only provide here the new combination, as the species itself requires redescription.
