Abstract
The Archipini fauna of the Caribbean is revised to include 33 species. Most previously described species occurring in the region are redescribed and figured, with 13 new species: Argyrotaenia brownisp. nov., A. crypticasp. nov. (including A. c. crypticassp. nov. and A. c. praeteritanassp. nov.), A. paradiseisp. nov., A. razowskianasp. nov., Claduncaria rawlinsanasp. nov., Cla. praedictanasp. nov., Cla. tainosp. nov., Clepsis davisisp. nov., Cle. deronisp. nov., Cle. jamesstewartisp. nov., Cle. peroniaesp. nov., Mictocommosis lesleyaesp. nov., and Mictopsichia nyhllindasp. nov. Three new combinations are proposed: Claduncaria mesosignaria (Razowski, 1999), comb. nov. (including Argyrotaenia thamaluncus Razowski, 1999, syn. nov.), Claduncaria minisignaria (Razowski, 1999), comb. nov., and Claduncaria chalarostium (Razowski & Becker, 2000b), comb. nov., stat. nov.Argyrotaenia granpiedrae Razowski & Becker, 2010 is reduced to subspecies rank under Argyrotaenia ceramica Razowski, 1999, resulting in Argyrotaenia ceramica granpiedrae Razowski & Becker, 2010, stat. nov. Four new synonymies are proposed: Clepsis labisclera Razowski & Becker, 2010, syn. nov. as junior synonym of Claduncaria maestrana Razowski & Becker, 2010; Clepsis pinaria Razowski & Becker, 2010, syn. nov. as junior synonym of Clepsis peritana (Clemens, 1860); and Argyrotaenia neibana Razowski, 1999, syn. nov. and A. ochrochroa Razowski, 1999 syn. nov. as junior synonyms of Argyrotaenia amatana (Dyar, 1901). Males of Argyrotaenia felisana Razowski, 1999, A. nuezana Razowski, 1999, and Claduncaria minisignaria (Razowski, 1999), comb. nov. are described for the first time; females of Argyrotaenia jamaicana (Razowski & Becker, 2000a) and Claduncaria ochrochlaena (Razowski, 1999) are described for the first time. The concept of Claduncaria is expanded and its diagnosis is modified to more clearly define its generic boundaries. A unique external sexual coupling mechanism in Claduncaria is discussed. Keys to the genera and species of Caribbean Archipini, distribution maps, a regional checklist, and Neighbor-joining and Maximum Likelihood trees based on COI barcode data are provided. Phylogenetic relationships among Caribbean Archipini are briefly discussed.
Highlights
The tribe Archipini has a worldwide distribution but is sparsely represented in the Neotropics (Razowski 1997, Razowski & Becker 2010)
We are unaware of any Neotropical Clepsis that large (i.e., the largest Neotropical species is Clepsis ecclisis (Walsingham, 1914), with a forewing length of 9 mm)
The larvae of Pandemis heparana have been recorded from an immense variety of important agricultural and ornamental plants in its native range (Brown et al 2008), so it is not unreasonable to assume it was introduced from Europe on imported plants, especially considering it has been introduced multiple times into North America (Mutuura 1980; JJD pers. obs.)
Summary
The tribe Archipini has a worldwide distribution but is sparsely represented in the Neotropics (Razowski 1997, Razowski & Becker 2010). The Archipini fauna of the Caribbean as a whole is poorly known, with the only taxonomic treatments being restricted to single islands or archipelagos (Razowski 1999; Austin et al 2019) or as part of a broader treatment of orphan taxa (Austin & Dombroskie 2020). The purposes of this revision are to describe new species in the Caribbean, propose new synonymies, redescribe and illustrate the previously described species, describe the opposite sex of multiple species, and note new distributional records. In addition to these structures, we have found that the terminal plate of the gnathos and presaccular gap (defined below) are informative
