Amorbia concavana (Zeller) (Lepidoptera: Tortricidae) is reported in Florida, USA. Male and female specimens are figured, and new host records are given. The species is compared to other Nearctic species of Amorbia Clemens. Florida specimens are more similar to Cuban than to Central American material with respect to male genitalia

Box 147100Gainesville, FL 32614-7100 USAJames.Hayden@FreshFromFlorida.comAbstract. Amorbia concavana (Zeller) (Lepidoptera: Tortricidae) is reported in Florida, USA. Male and femalespecimens are figured, and new host records are given. The species is compared to other Nearctic species of AmorbiaClemens. Florida specimens are more similar to Cuban than to Central American material with respect to malegenitalia.IntroductionAmorbia Clemens (Tortricidae: Sparganothini) includes 29 species distributed in the New World(Phillips-Rodríguez and Powell 2007), of which Powell and Brown (2012) report two in Florida, USA. Athird, Amorbia concavana (Zeller), is also established in southern Florida. I identified the species andsolicited confirmation too late for inclusion in the Moths of North America fascicle on Sparganothini(Powell and Brown 2012), so I intend this note to supplement that treatment.The earliest known records are four males caught by Jim Vargo on 23 February 2004, two miles eastof Florida City (Miami-Dade County), and a fifth on 6 March 2005 (J. Vargo, pers. comm. 2012). FromApril 2006 through early 2008, large numbers of males were caught in traps baited with a pheromone forSpodoptera litura (F.) (Lepidoptera: Noctuidae) as part of the Cooperative Agricultural Pest Survey(CAPS) Spodoptera program and submitted for identification to the Florida Department of Agricultureand Consumer Services, Division of Plant Industry (FDACS-DPI). A few female specimens were subse-quently obtained by rearing and submitted to DPI. The species has been photographed in the wild andposted on the Moth Photographers Group website (Patterson 2012).MaterialsDissections were made according to Robinson (1976). Initial identification was based on informationin Phillips-Rodríguez and Powell (2007) and confirmed by J. Powell (pers. comm., Essig Museum ofEntomology, Berkeley, CA) and J. Brown (pers. comm., USDA-ARS). Photographs were taken with anAuto-montage Pro 5.01 (Syncroscopy; Synoptics Ltd.) using a JVC digital camera and Leica Z16APOlens at FDACS-DPI. Specimens are deposited in the Florida State Collection of Arthropods (FSCA,Gainesville, Florida, USA) and the National Museum of Natural History (NMNH, Washington, D.C.).Unless a depository is listed below, records of specimens that were returned to collectors, discarded, orlost, mostly from 2008, were obtained from the FDACS-DPI regulatory database.Amorbia concavana (Zeller, 1877)(Fig. 1–7)Material examined.

Males of A. concavana can be distinguished from Nearctic congeners by the presence of acostal fold (Fig. 3) and cornuti that are perpendicular to the longitudinal axis of the phallus (Fig. 6). Thefemales key out to Amorbia Clemens in Powell and Brown (2012: 27), but most males run to CoelostathmaFigures 1–7. Amorbia concavana specimens from Florida. 1) Male, right wings (Homestead, FL, 3 Dec. 2007,FSCA; scale = 5 mm). 2) Male, right wings (Homestead, FL, 28 Nov. 2007, FSCA; scale = 5 mm). 3) Male costal fold.4) Female habitus (Homestead, FL, 11 Jan. 2012, FSCA; scale = 1 cm). 5) Unspread female (Homestead, FL, 21 Oct.2011, FSCA; scale = 1 cm).INSECTA MUNDI 0271, December 2012 • 3 FIRST U.S. RECORDS OF AMORBIA CONCAVANAClemens because of their small size. They differfrom Coelostathma in lacking ocelli, having a cos-tal fold, and having the sacculus with small ven-tral projections rather than elongate subbasal ordistal processes. Among Amorbia species, bothsexes key out to A. emigratella Busck or A. veroPowell and J. Brown (Powell and Brown 2012: 29).Those species differ in lacking a distinct saccularprocess, and A. vero has less strongly coloredscales on the apex of the hind wing and a slightlynarrower signum than other congeners. BesidesA. concavana, only A. vero and A. humerosanaClemens are currently recorded in Florida (Powelland Brown 2012); the latter species is easily dis-tinguished by its gray color and large size (fore-wing length 10–16 mm).Descriptive notes. Males have beige forewingswith scattered black and silver scales (Fig. 1–2).The hind wings are pale yellow-beige without atransparent area, and the apex is distinctly darkorange with black scales. Females are similar buthave darker, rather orange forewings with lessblack scaling (Fig. 4–5). The quantity of blackscales on the male forewing is variable amongFlorida specimens, but they are otherwise quitehomogeneous. The male forewing length is 6.0–8.0 mm (mean = 7.1 mm, n = 27), and the femaleforewing length is 10.0–12.0 mm (mean = 11.0mm, n = 4). The venation is as in other Amorbiaspecies, with sexually dimorphic forewing radialveins. The male genitalia (Fig. 6; n = 3) have oneshort saccular spine that is consistent in length among examined material. The corpus bursae has abroad, band-shaped signum typical of Amorbia (Fig. 7).Remarks. The male genitalia differ somewhat from those of Central American populations, representedby a Honduran specimen in Fig. 84 of Phillips-Rodríguez and Powell (2007). Those have a distinctlyemarginate sacculus and a longer saccular process, whereas Floridian specimens have a nearly straightsacculus and short spine. However, they are more similar to the illustration of A. phaseolana Busck inBusck ([1934]: pl. 30 fig. 4), a Cuban species synonymized with A. concavana by Phillips-Rodríguez andPowell (2007). Lambert (1950) also illustrated a short saccular spine in A. concavana, but he did notstate the dissection’s provenance. The Cuban population may prove to be a distinct species from theCentral American one, with the Floridian population conspecific with the former, but a decision on thestatus of A. phaseolana will depend on examination or sequencing of Cuban specimens.The female was not available to Phillips-Rodríguez and Powell (2007), but Busck ([1934]: pl. 36 fig.8) illustrated the female of A. phaseolana and noted that it was much larger than the male. Photographsof both sexes and larvae are available online in Janzen and Hallwachs (2012).Phillips-Rodríguez and Powell (2007) suggested that Amorbia effoetana (Möschler), described fromone female specimen from Puerto Rico, could be conspecific. The type specimen was not examined byLambert (1950) nor by Phillips-Rodríguez and Powell (2007), and it is still absent from the Museum fürNaturkunde (W. Mey, pers. comm. 2012). Although  nomenclaturally unavailable, Lambert (1950) syn-onymized A. phaseolana with A. effoetana and illustrated male genitalia very similar to Fig. 6; it isunknown whether his figure represents Cuban or Puerto Rican populations. Möschler described thespecies as having “graubraun” (brownish gray) hind wings, so it may well be specifically distinct.Figures 6–7.

Amorbia concavana is polyphagous (Busck [1934]; Phillips-Rodríguez and Powell, 2007; Janzenand Hallwachs 2012) with some preference for Fabaceae. The records on Rosa L. sp. (Rosaceae) andMikania micrantha Kunth (Asteraceae) are novel. The latter is a fast-growing weed that is invasive inFlorida (Anderson et al. 2012).Distribution. Amorbia concavana is distributed from northern Mexico (Tamaulipas) to Panama andalso in Cuba (Phillips-Rodríguez and Powell 2007). Most of the Florida records are from Miami-DadeCounty around Homestead and Miami, but one specimen is known from Dania Beach, Broward County.Photograph vouchers posted on the Moth Photographers’ Group (Patterson 2012) include specimensfrom near Florida City, February 2004 (J. Vargo); Davie, May 2006 (P . Ayick); and Anhinga Trail, inEverglades National Park near the main entrance, February 2012 (C. Wolf).AcknowledgmentsI kindly thank Jerry Powell (Essig Museum, Berkeley, CA) and John Brown (USDA-ARS) for con-firming the identification and Wolfram Mey for searching for the type specimen of A. effoetana again inthe ZMHB.

Paul Ayick, Carol Wolf, and Jim Vargo kindly made available theircollection data.
