Synonyms and other taxonomic changes
Curtara insularis (Caldwell & Martorell, 1952)
♂ 8mm, ♀ 8.5mm
"Crown more than twice as wide between eyes at base as median length, depressed just behind anterior margin. Generally pale brown with dark spots." — DeLong & Freytag, 1976
Males are more heavily marked with brown to black spots than paler females. Has a much shorter head than members of Negosiana.
southeastern U.S. to Argentina
This species has been a source of confusion for some time. For years it was placed under the name Negosiana miliaris on BugGuide and sister sites due to process of elimination and incorrect occurrence and range records. Eventually we found that what we were previously calling "Negosiana miliaris" was likely the species Curtara insularis—a Caribbean species officially recorded in Florida at least dating back to 2009 (decades of prior collecting not turning up any individuals) [the first BugGuide record is from 2004]. This widespread species (which likely ranges to Argentina) has since spread throughout the eastern United States and into northern Mexico (if our assessment of its identity is correct). Specimens still need to be collected and analysed throughout its range, but it is almost certainly this species.
Joel Kits states in personal communication to Solomon Hendrix:
"I suspect C. insularis may be a senior synonym of Curtara samera described from Brazil and Argentina, as the illustrations of the genitalia are nearly identical. This suggests it may be a widespread Neotropical species, or maybe native to Brazil and Argentina and introduced to Puerto Rico and the southeast states. A barcode I sequenced from a specimen from Florida matches a barcode cluster [] that includes specimens from both Florida and Argentina."
