Augochloropsis (Paraugochloropsis) anonyma Cockerell

Augochlora anonyma Cockerell, 1922: 15 ♀. Holotype: ♀ USA, Florida, No Name Key [USNM, catalog #53678 barcode #: 00536758, Type #: 2489]. Images examined by ZP and MA. Online record: http://n2t.net/ark:/65665/347b15a43-e8d1-4195-8eaf-f8ac9cbbec94 (labels read "No Name / Key 3.98 Fla // GN Collins / Collector // CL Pollard / Collector // TypeNo. / 24890 / U.S.N.M. [red label] // Augochlora / anonyma / Ckll. TYPE.").

Augochloropsis cuprea (in Sandhouse 1937 [in part]: key).

Augochloropsis (Paraugochloropsis) anonyma (in Mitchell 1960: key, redescription of female, first description of male; Hurd 1979: catalog).

Diagnosis.

Both sexes of Augochloropsis anonyma can be recognized by the short propodeal triangle, which is impressed and narrower than the metanotum (Fig. 17E ). Augochloropsis anonyma are most likely to be confused with Augochloropsis viridula , as they overlap in range, and both have shining integument and poorly developed apical hair fringes on the metasoma. Augochloropsis anonyma females can be recognized by the presence of dark pubescence on T2-T4, whereas Augochloropsis viridula lacks dark pubescence. In addition, Augochloropsis anonyma has the propodeum dorsal surface impressed, shining, and relatively narrow with its medial length slightly less than the medial length of the metanotum (Fig. 17E ). In comparison, Augochloropsis viridula has the propodeum dorsal surface flat throughout, not impressed, and relatively broad, its medial length dorsally as long (or longer) than the medial length of the metanotum (Fig. 17C ).

Augochloropsis anonyma is also similar to Augochloropsis fulgida because both share the character of dark hairs on the metasoma (see Fig. 23C, D for Augochloropsis fulgida ). However, the narrow propodeal triangle of Augochloropsis anonyma (Fig. 17E ) separates these two species, as Augochloropsis fulgida has the propodeal triangle broader (visible in Fig. 23C ).

Comments.

Augochloropsis anonyma is known from the far southeastern US, and we have examined material from Florida and Georgia (Fig. 18 ). Mitchell (1960) reports it occurring as far north as North Carolina.
