“ U.S.A., FL, Miami-Dade Co. / Montgomery Botanical Center / 11-XI-2022 / Coll.: B.W. Bahder / Sweeping palms / Agoo fulvus ♂ ” (FLREC).
“ U.S.A., FL, Lee Co., Estero / 12.VI.1980 / Van Duzee” (Holotype male).
Sequence Data. For A. keili sp. nov. molecular data for the COI, 18S and D9-D10 expansion regions of 28S were generated and accessioned (Table 2). The molecular phylogeny generated based on 18S, 28S and COI show strong bootstrap support (100, 100 and 93, respectively) for the monophyly of Agoo, with A. keili sp. nov. resolving within the clade for all markers (Fig. 7). In addition, the consensus tree generated based on concatenated 18S, 28S and COI data also demonstrated strong bootstrap support for the monophyly of Agoo with A. keili sp. nov. resolving within Agoo adjacent to A. luzdenia with strong bootstrap support (98).
Remarks. The morphological characters observed (rounded/circular head shape in lateral, general wing venation and spinulation of aedeagus with large, apical processes of endosoma and basal retrose processes) support the placement of the novel taxon in the genus Agoo. Further supported by the strong molecular evidence for three separate loci. In addition, the similar morphological characters observed in A. keili sp. nov. along with strong molecular support indicate that the new species be placed in Agoo. Initially, the pale form and yellow form were sorted as two different species due to general color and pattern, thus far, being reliable for species diagnosis. However, after examination of the genitalia it was evident that they were the same. In addition, molecular data was generated for both forms and were 100% identical for all three loci (data not shown). It is unknown if this is due to the presence of true color morphs or is potentially age related, but not observing this degree of color variance in the large number of specimens examined for other species of Agoo in previous studies make it likely the variance observed in A. keili sp. nov. is the presence of true color morphs.
Agoo keili sp. nov. can be recognized as a pale species, lacking strong markings. Pygofer of male terminalia bearing a large broadly triangular medioventral process. Gonostyli in ventral view bearing roughly quadrate process just distad of midlength. Aedeagus bearing large, subtriangular processes on dorsolateral margins of the shaft. Endosoma bearing 5 pairs of processes, with triangular projection on dorsal margin near apex. Anal segment tube broadly triangular, with apex caudally projected (not downcurved), lobed, not downcurved apex strongly bilobed from dorsal view. The most similar species might be the Jamaican species A. beani, which is roughly similar in color and shares some male genitalic structures but the dorsolateral margins of the shaft bear elongated processes (not subtriangular), the endosoma bears fewer processes and lacks the triangular projection on dorsal margin near apex; also the median processes on the gonostyli (ventral view) are roughly triangular (not quadrate). In addition, it also superficially resembles A. xavieri in general body color, however, A. xavieri possesses a fuscous stripe along the length of the forewings. While the general scheme of the pygofer, gonostyli and anal segment resembles A. xavieri, the aedeagus is significantly different. Interestingly, based on the molecular evidence at hand, A. keili sp. nov. appears mostly closely allied to A. luzdenia, however is easily distinguished from it based solely on wing pattern (A. keili sp. nov. lacking patterns and A. luzdenia possessing a half fuscous, half red stripe along length of forewing with a black spot near the apex).
