Oligonychus daleae Tuttle, Baker & Abbatiello, 1976 Oligonychus daleae Tuttle, Baker & Abbatiello, 1976: 86. Host and distribution. Dalea sp. ( Leguminosae ); Mexico. Remarks. Oligonychus daleae Tuttle, Baker & Abbatiello was described from females only, and details of the male were unknown ( Tuttle et al. 1976 ). The authors did not specifically compare it with any other closely related species. However, O. daleae females were differentiated from the females of O. propetes (described from USA on Quercus alba ) and O. quercus (described from Mexico on Quercus sp.) in a diagnostic key, using the striae pattern and comparative length of setae on the dorsal hysterosoma ( Tuttle et al. 1976 ). These three species share similar geographical distributions ( Migeon and Dorkeld 2021 ). The species identity of O. daleae will be clear after collecting and describing the male from the type host and locality.
