Print Fact SheetBagnalliella mojave

Distinguishing features

This species has not been studied by the present authors, but see Cott, 1956: 91-93.

Related species

Nine species are listed in the genus Bagnalliella. Seven of these are from Yucca plants in southwestern USA and these are clearly closely related to each other in structure. In contrast, the other two (from New Guinea and South Africa) should probably be placed in other genera. Cott (1956) distinguished the three species of Bagnalliella recorded from California on the following basis: B. yuccae has two sense cones on antennal segment III and four on IV; B. mojave Hood has one sense cone on antennal segment III and two on IV; B. desertae Hood has one sense cone on antennal segment III and three (? four) on IV. Despite this, variation in the number of these sensoria within and between populations requires further study. Tree (2010) noted that in a population of B. yuccae introduced to Australia the number of sensoria on antennal segment III varied from 2 to 3, and the number on segment IV varied from 2 to 4.
