Loxaulus boharti Dailey and Sprenger, New Species

Host: Quercus dunnii [palmeri]

Integral stem gall, larval cells 2 mm in diameter, develop in wood under bark, stems slightly lumpy though lumps barely noticeable until insects emerge. Similar to gall of Loxaulus brunneus ... Insects emerge in late March and early April from 2-year-old twigs and only the basal half of prior year twigs.

Galls similar to the above were collected on . . . Quercus cedrosensis. No insects were reared.

Distribution: Baja California, CA

Loxaulus boharti
Stem-gall wasp
[Page 144]

Hosts: Quercus palmeri

This cynipid wasp, which induces integral, slightly swollen, polythalamous galls, is known to occur only on Palmer's oaks.

Range: "island patches" of Q palmeri in Contra Costa and Riverside counties, CA; northern Mexico

Loxaulus boharti Dailey and Sprenger [the description Melika and Abrahamson give for this gall does not match the original description or the one given by Russo and may have been given in error. Other agamic galls in the genus Loxaulus are integral stem galls and the gall described below would be anomalous for the genus.]

Distribution: CA, Baja California

Biology.--Only the unisexual generation is known. It induces yellow, pubescent aborted axillary bud or leaf petiole galls on Quercus dunnii. Adults emerge in December and January.
