Chlamisus Rafinesque

( Figs. 1 D ; 2 C ; 3 C ; 4 C ; 5 C ; 7 B , D)

Chlamys Knoch, 1801: 122 . Type species: Chlamys foveolata Knoch, 1801 , by subsequent designation of Navajas, 1946: 244 [preoccupied by Chlamys Bolten, 1798 , Mollusca]. Chlamisus Rafinesque, 1815: 116 (new name for Chlamys Knoch ).

Diagnosis. Length 3.09-7.72 mm, width 1.90-5.36 mm. General body shape cylindrical. Body usually not metallic in color. Frons in canthus of eye usually without yellow spots (face may be entirely or partly yellow, with yellow area extending into canthus, but elytra do not have velvety spots). Frons glabrous or (rarely) covered with dense hairs. Pronotum and elytra usually glabrous or (rarely) covered with dense short hairs. Antenna serrate beyond 3 rd or 4 th antennomeres, 2 nd antennomere slightly widened, globose, 5 th antennomere nearly as large as 6 th. Pronotum medially elevated, with various bumps and short carinae. Pronotal base opposite mesoscutellum (posterior pronotal lobe) with well differentiated notch. Prosternum posteriorly narrowed, posteriorly much narrower than anterior margin. Anterior margin of metasternum concave. Mesoscutellum short, transverse. Metascutellum not exposed. Sutural serration of elytra usually incomplete (suture entire immediately following mesoscutellum). Elytral tubercules well developed. Males without spines or spinulae on first ventrite. Tibiae slightly curved, slightly flattened, with sharp dorsal edge. Fore- and midtibial apices with spine. Tarsal claw appendiculate. Male ejaculatory guide (part of internal sac of aedeagus) symmetrical, without sheath. Apex of spermathecal duct as wide as rest of pump.

Distribution. Cosmopolitan ( Monrós 1952; Reid 1991).

Remarks. Chlamisus is close to Exema and Neochlamisus . From Neochlamisus it can be separated by the following characters: body usually not metallic in color; frons in canthus of eye usually without yellow spots (face may be all or partly yellow, with yellow area extending into canthus, but elytra do not have velvety spots); and male ejaculatory guide symmetrical, without sheath. From Exema it can be separated by the following characters: males without spines or spinulae on first ventrite; 5 th antennomere nearly as large as 6 th; sutural serration of elytra usually incomplete (suture entire immediately following mesoscutellum); and prosternum posteriorly pointed (narrowed), posteriorly much narrower than anterior margin.

No Australasian species were examined for this study, but according to Reid (1991) native Australasian species of Chlamisus do not fit into any current definition given for either American ( Karren 1972; Monrós 1951) or Oriental ( Gressitt and Kimoto, 1961) species. Reid (1991) also recognized several characteristics distinguishing Oriental (South-East Asian) and American species.

Comparison of the paratype of Chlamisus rousei Medvedev, 1993 described from Puerto Rico with specimens of Chlamisus straminea Suffrian, 1866 from Puerto Rico and Virgin Islands revealed that they are conspecific, therefore we here synonymize these names.

There are approximately 400 species of Chlamisus in the world ( Monrós 1952; Reid 1991); approximately 100 Neotropical, 45 Palearctic, 18 Nearctic, 22 Oriental, 6 Afrotropical, and 2 Australasian (naturally occurring).
