Stilobezzia (Stilobezzia) thomsenae Wirth

Stilobezzia (Stilobezzia) thomsenae Wirth, 1953: 83 (Florida) ; Borkent and Spinelli 2000: 55 (in New World catalog south of the USA; distribution); Borkent and Spinelli 2007: 87 (in Neotropical Catalog; distribution); Grogan et al. 2010: 41 (new Florida records; comparison with S. bulla Thomsen ).

Stilobezzia scutata Lane and Forrattini, 1961: 92 ( Panama) .

Discussion. Wirth’s (1953) original description of this species was based on two specimens from Florida, the holotype male from Collier Co., and a female from Citrus Co. about which he stated “…is provisionally referred to S. (S.) thomsenae , since it resembles the male in coloration, although it may prove to be a dark specimen of S. (S.) bulla .” Under “diagnostic characters” for S. thomsenae, Wirth (1953) noted that it was “Very closely related to, and almost indistinguishable from bulla Thomsen , except for the very characteristic male genitalia.” This species is also known from Panama and Yucatan, Mexico ( Borkent and Spinelli 2007). Grogan et al. (2010) reported on additional records of this species from Florida and new records from Jamaica in the FSCA and noted that both sexes of S. thomsenae lack a fringe of macrotrichia on their anterior wing margin that is present in males and females of their very similar related Nearctic species, S. bulla Thomsen. We provide the first records of this primarily Neotropical predaceous midge from Guadeloupe.
