| Abstract: | Larvae of the California oakworm, Phryganidia californica, collected in August 1958 in Orcutt, California, were infected by two eugregarines, Leidyana phryganidiae n. sp. and L. berkeleyi n. sp. Both gregarines inhabit the intestine of larvae, and their sporonts are solitary. The maximum length of sporonts of L. phryganidiae is 633 μm; the ratio of length of protomerite to total length (LP:TL) ranges between 1:6.6 and 1:9.6, and the ratio of width of protomerite to width of deutomerite (WP:WD) ranges between 1:1.3 and 1:2.2. The protomerite is conical, longer than wide, and the deutomerite tapers sharply to a point. The maximum length of sporonts of L. berkeleyi is 422 μm; the ratio LP:TL ranges between 1:4.6 and 1:11.2 and WP:WD between 1:0.9 and 1:2.1. The protomerite is hemispherical, and the deutomerite is cylindrical. This is the first record of eugregarine infection in a phytophagous lepidopteran. |
