Forcipomyia (Thyridomyia) nodosa Saunders

Forcipomyia (Thyridomyia) nodosa Saunders, 1959: 43 ( Costa Rica); Wirth 1970: 434 ( Colombia, Mexico records); Dow and Wirth 1972: 186 (Arizona, Kansas, Mississippi records); Borkent and Grogan 2009: 10 (in Nearctic catalog; distribution).

Discussion. Although this species was originally described by Saunders (1959) from specimens collected in Costa Rica, it was also subsequently recorded from Colombia and Mexico by Wirth (1970), and in Arizona, Kansas and Mississippi by Dow and Wirth (1972). As mentioned in the discussion section of F. (T.) johannseni , a female from Vero Beach, St. Lucie Co., FL identified by Wirth (in Dow and Wirth 1972) as that species, is apparently a specimen of F. (T.) nodosa . This female lacks a palpal pit, a characteristic of F. johannseni , however, its third palpal segment is moderately short and broad with numerous subapical sensilla and the spermatheca has a curved neck, all of which are characteristic of female F. nodosa , and it represents the first record of this species from Florida. However, a male from the same site in St. Lucie Co. has genitalia that differ from illustrations of male F. nodosa in Wirth (1970) and Dow and Wirth (1972) as well as two males of this species we examined that were collected in Cochise Co., Arizona in 2007 by WLG. The proximal 2/3 of tergite 9, all of sternite 9 and the basal arms of the aedeagus are missing from this St. Lucie Co. male and it has a heavily sclerotized transverse sclerite at the base of the heavily sclerotized lateral sclerites of the aedeagus and very short gonocoxites, and these differences suggests that it may belong to an undescribed species.
