Description of Atrichopogon Wirthi New Species (Diptera: Ceratopogonidae) from Leaves of the Water Lettuce (Pistia Stratiotes) in Florida
Abstract
A new species of Atrichopogon (Diptera: Ceratopogonidae), whose immature stages are found on leaves of the water lettuce, Pistia stratiotes L., is described in all stages. The adults have a glossy black head and thorax, white abdomen, and dark terminal tarsal segments. The pupa possesses large, elongate tubercles and bears dark brown mediodorsal and dorsolateral pigmented spots on the first six abdominal segments. The larva is atypical, resembling those of the subgenus Forcipomyia. The larva does not resemble any of the Atrichopogon species figured by Ewen and Saunders (1958). The species is quite distinct and different from the seven described Florida species of Atrichopogon listed by Wilkening et al. (1985).Downloads
