Kuwayama caldwelli (Tuthill, 1944) , new combination

Rhinopsylla caldwelli Tuthill 1944a: 6 .

Trioza caldwelli (Tuthill) ; Burckhardt and Lauterer 1997b: 115.

Materials examined. No FSCA specimens.

Diagnosis. Description by Tuthill (1944a, as Rhinopsylla caldwelli ). Separated from other Florida psyllids as indicated in the generic key above.

Distribution. USA (FL) ( Hodkinson 1988).

Host plants. Unknown.

Comments. Virtually nothing is known about this psyllid. According to the description, it was found in Bonefish Key, which has been subsumed by Fat Deer Key (Monroe County). As far as we know, it has never been collected again.

This species was described by Tuthill (1944a) in Rhinopsylla Riley, 1885 , probably because the head that is “scarcely cleft anteriorly.” When synonymizing Rhinopsylla with Bactericera Puton, 1876 , Burckhardt and Lauterer (1997b) transferred the species to the artificial genus Trioza Foerster, 1848 , as it did not fit the generic definition of Bactericera . Tuthill (1944a) mentioned in his description the broadly rounded genae, similar to Kuwayama Crawford, 1911 , and the large clypeus. While Kuwayama in its present definition is highly artificial, it can be restricted to a group of triozids defined by the rounded genae, the adpressed, hemispherical eyes, the large bulbous clypeus and the long rostrum. The group is Neotropical in distribution and restricted to Compositae. As Trioza caldwelli fits this definition, we formally transfer it here as Kuwayama caldwelli (Tuthill, 1944) , comb. nov. from Rhinopsylla .
