named to honor of David G. Marqua (1924–2017), beetle collector and Davis Mountains’ resident. Dave’s former residence at 5,800 ft. in the Davis Mountains is likely the best entomologically-known locale in the Davis Mountains, due to his personal collecting efforts, his warm friendly nature, and his long-standing invitation to countless insect collectors.
