The only reliable way to distinguish Paectes arcigera from Paectes asper Pogue is by characters in the male and female genitalia. Male genitalia of Paectes arcigera consist of a reduced, fingerlike valve and costa, and a greatly expanded free saccular extension (Fig. 29). In Paectes asper the valve is triangulate, the costa has a truncate apex, and the free saccular extension (Fig. 33) is approximately half the width as in Paectes arcigera. Female genitalia of Paectes arcigera have a large, half-round ostium bursae covered with thorn-like spines and the lateral apices of the eighth sternite are not produced (Fig. 37). In Paectes asper, the ostium bursae is a crescent-shaped invagination covered with fine spicules and the lateral apices of the eighth sternite are produced (Fig. 40).

Adults. Sexes dimorphic. Male. Head – antenna broadly bipectinate to 3/5 length, then filiform; eyes large, globular; vertex with broad scales, cream colored, thin black lines adjacent to scape; frons with broad scales, projecting slightly beyond anterior eye margin, mostly cream colored with a few gray and ferruginous scales, two black dots along eye margin, one ventral to antenna, other dorsal to palp; labial palp porrect, mixture of cream-colored, gray, and ferruginous scales, internal surface white. Thorax – prothorax somewhat variable, well-marked specimens cream colored with medial ferruginous band, anterior margin a thin black line, posterior margin gray to black and not as well defined as anterior line; patagium with cream-colored hairlike scales mixed with ferruginous, gray, and black scales; protibia cream colored mixed with a few black scales; tarsi gray with white apical bands; middle legs mixture of cream-colored and pale gray scales, scales much longer than either the pro- or hind tibia, tarsi pale gray with cream-colored apical bands; hind tibia cream colored, tarsi cream colored; underside with white hairlike scales; forewing length 9.5–12.2 mm; costal area a gray; ovate basal spot white in ventral half, pale gray white-tipped scales in dorsal half; antemedial line thin, black, from posterior margin to Cu vein, forming ventral border of basal spot; medial area between antemedial and postmedial lines mostly white mixed with pale-gray scales; some specimens with medial line consisting of two very thin crescent-shaped lines from posterior margin to just below M3 vein; reniform spot obscure, consists of two small ferruginous dots in a vertical pattern, or may only be represented by a single dot in some specimens; postmedial line a mixture of ferruginous and black scales, double line from posterior margin to vein M2 then single until merging with black dash at vein R5 that extends to outer margin; white apical spot; subterminal area variable, gray to cream colored, mixed with ferruginous scales; terminal line a series of black dashes between veins; fringe light brown to gray with gray patches at wing veins resulting in a somewhat checkered appearance; hind wing with marginal shading dark gray, veins highlighted dark gray, white between veins and at base, anal fold a white and dark gray striped pattern.

Genitalia (Fig. 29) – Uncus triangulate, apex recurved and pointed, 0.62–0.64 × length of subscaphium; subscaphium triangulate, decurved, pointed apex; valve membranous, reduced, widest at base and tapering to a fingerlike projection, setose; costal margin sinuate, apex produced, fingerlike projection wider than valve, setose; sacculus well developed, proximal half fused with valve, distal half free, elongate, broad, curved inward, longer than valve, apex broadly rounded; saccus U-shaped; aedeagus straight, slightly curved in distal half, dorsum near apex covered with minute spicules; vesica irregularly-shaped oval, wide diverticulum lateral to apex of aedeagus, a long, flat cornutus at base of vesica directed posteriorly, short, thumb-like diverticulum near apex and adjacent to irregular sclerotized area bearing a short, narrow cornutus. Female. As in male except:antenna filiform; forewing length 9.8–11.6 mm;medial area less contrasting with fewer white scales than male; overall more drab in appearance than male. Genitalia (Fig. 37) – Papillae anales ovate, soft, fleshy, covered with numerous setae; anterior apophyses fused with eighth segment; posterior apophyses present; venter of eighth segment covered with minute spicules; ostium bursae sclerotized, rectangulate, dorsal invagination covered with thorn-like spines, dorsal spines largest; base of ductus bursae rectangulate and fused with eighth segment; ductus bursae juncture with appendix bursae below base, striate; duct of appendix bursae narrow, striate 2/3 length; appendix bursae membranous, round; corpus bursae ovate to round, covered internally with numerous thorn-like signa.

. Paectes arcigera is restricted to the eastern Caribbean Islands from Puerto Rico and the Lesser Antilles, including U.S. Virgin Islands, British Virgin Islands, Guadeloupe, Dominica, St. Lucia, and Trinidad (Fig. 48). Probably flies throughout the year with flight records for all months except February. Nothing is known about biology or host plants. McMullen (1986) remarked that adults of Paectes arcigera were seen near Crytocarpus pyriformis Kunth (Nyctaginaceae) on Isla Santa Fe, Galapagos Islands, but this record can be referred to Paectes nana.

Paectes arcigera has been confused in collections and in the literature as Paectes obrotunda. Kimball (1965) and Minno (1992) listed Paectes arcigera as occurring in Florida, but these are based on a broad concept of Paectes arcigera that made this revision of the species complex necessary. These Florida records are now known to be referable to Paectes asper and Paectes nana. Franclemont and Todd (1983) and Lafontaine and Schmidt (2010) also listed Paectes arcigera as occurring in North America, unaware that the name represented a species complex. Askew (1994) listed Paectes arcigera as occurring on Little Cayman Island, but this is probably referable to Paectes asper. Paectes arcigera and Paectes asper occur sympatrically in the U.S. Virgin Islands, British Virgin Islands, and Dominica.

Holotype male – BRAZIL: Bahia, nr. Salvador airport (12.91007°S, 38.3380°W), March 2010, R. Diaz, V. Manrique, M. Vitorino; USNM ENT 00148675; HOLOTYPE / Paectes longiformis Pogue” [red label]. UFPC. Paratypes – (29 males, 30 females) Same data as holotype; genitalia slide male USNM 134921; genitalia slides female USNM 135919, 135976, 135920, 135015, 135016. UFPC, USNM, CNC, BMNH.

Paectes longiformis is most likely to be confused with Paectes similis Pogue, but can be differentiated by the color of the medial area of the forewing. In Paectes longiformis (Figs 5–6), the medial area is cream colored interspersed with some dark-ferruginous scales and in Paectes similis (Fig. 7) this area is shiny white with some gray scales. The tarsi in Paectes longiformis are dark gray, whereas in Paectes similis they are mostly white with some gray scales. There are several differences in the male genitalia to differentiate Paectes longiformis from Paectes similis. The uncus is 0.62–0.70 × the length of the subscaphium in Paectes longiformis (Fig. 30) and 0.80 × in Paectes similis (Fig. 31). The distal, free saccular extension is longer than the valve in Paectes longiformis (Fig. 30) and shorter than the valve in Paectes similis (Fig. 31). The female genitalia are easily separated from the other species in this group by the form of the lateral margins of the eighth sternite. In Paectes longiformis, the lateral margins of the eighth sternite are slightly produced and form a right angle (Fig. 38). In Paectes arcigera and Paectes nana, the lateral margins are not evident (Figs 37, 39) and in Paectes asper, Paectes medialba Pogue, and Paectes sinuosa Pogue, the lateral margins are produced (Figs 40–42).

Known only from the type locality in northeastern Brazil in the state of Bahia (Fig. 49). Larvae have been reared from the Brazilian peppertree. It is possible that this species has a much broader range, considering the wide range of its host plant, but so far no other specimens have been collected.

As a potential biological control agent against the Brazilian peppertree in Florida, baseline data was developed about the biology and temperature requirements of Paectes longiformis (Manrique et al. 2012).

Paectes nana has two distinct forms. The most easily recognized bears exaggerated dark markings on the apical portion of the postmedial line that is contiguous with the subapical dash, the posterior portion of the postmedial line from CuA1 to posterior margin, and the antemedial line from just dorsal to anal vein to posterior margin (Fig. 11). This form is not present in Paectes asper. The other form of Paectes nana most resembles both Paectes asper (Figs 8–10). The forewing costa in Paectes nana is gray with small, faint, dark-gray quadrate spots along the margin at approximately 1/4 and 1/2 length of wing. In Paectes asper the forewing costa is ferruginous mixed with some gray and the quadrate spots are absent (Figs 12–15). In females of Paectes nana (Figs 10–11), the medial area of the forewing is gray, or can have gray scales tipped with white, giving a slightly lighter overall color than the remainder of the forewing. In Paectes asper, the medial area is somewhat lighter in coloration than the remainder of forewing and entirely white scales are present as are white-tipped gray scales (Figs 16–18). A cream-colored basal spot is present and contrasts with the remainder of the forewing in Paectes asper, and in Paectes nana the basal area is only very slightly contrasting with white-tipped gray scales.

Both the male and female genitalia are distinct between these species. In the male genitalia, the costa is thumb-like with a more produced apex in Paectes nana (Fig. 32), whereas in Paectes asper the costa in truncate and the apex is not produced (Fig. 33). In Paectes nana, there are several flat setae arising from a sclerotized ridge on the dorsal surface of the valve (Fig. 32), these flat setae are absent in Paectes asper (Fig. 33). The cornutus at the base of the vesica is wide in Paectes nana (Fig. 32), but narrow in Paectes asper (Fig. 33). In the female genitalia, Paectes nana is easily recognized by the ostium bursae being a sclerotized circle (Fig. 39), but in Paectes asper the ostium is crescent shaped (Fig. 40).

Paectes nana is widespread from Florida through the Greater Antilles, except for Puerto Rico, and from Mexico to Costa Rica; in South America distributed from Venezuela, Colombia, and northern Ecuador (Fig. 50). It has been introduced to the Galapagos Islands (Roque-Álbelo and Landry 2011).

Paectes nana is a native species from Florida that has been reared from Brazilian peppertree in several counties, including Hernando, Lee, Levy, Monroe, and St. Lucie. Larvae that were collected in September and October had a pupal stage from 9–18 days and larvae collected in January and February had a pupal stage from 11–15 days. Adults probably fly all year with recorded dates from January–March, June–July, September–October, and December. Dyar (1901) stated that larvae of Paectes nana (referred to as Paectes burserae) are common on gumbo-limbo (Bursera simaruba (L.) Sarg., Burseraceae). In Costa Rica Paectes nana collecting dates range from May through November and has been reared from Bursera simaruba and Bursera tomentosa (Jacq.) Triana & Planch.

Paectes nana has two forms. A form that is easily confused with Paectes asper and a more boldly marked form where the antemedial and postmedial lines and marginal dash are heavily marked with black and there are scattered black scales along the forewing posterior margin adjacent to the antemedial line. The holotype of Paectes nana is a heavily marked form.

The species name is the Latin term for rough, which refers to the roughened texture of the apex of the free saccular extension in the male genitalia.

The forewing costa is ferruginous with some gray in Paectes asper and mostly gray with some ferruginous in Paectes arcigera. The medial area of the forewing is mostly white with a white apical spot in Paectes asper; in Paectes arcigera these areas are cream-colored.

The male genitalia are easily differentiated between Paectes asper and Paectes arcigera. The valve in Paectes asper has thick, curved dorsal setae; in Paectes arcigera the setae are hairlike. The costa is truncate in Paectes asper but triangulate in Paectes arcigera. The free saccular extension is narrow in Paectes asper and wide with an expanded apex in Paectes arcigera.

The female genitalia have small, curved lateral projections at the base of the eighth sternite in Paectes asper; these projections are absent in Paectes arcigera. The ostium bursae is crescent shaped bearing minute spicules in Paectes asper whereas in Paectes arcigera the ostium bursae is semicircular in shape and bears large conical spines.

Genitalia (Fig. 33) – Uncus triangulate, apex sharply recurved and pointed, 0.62–0.64 × length of subscaphium; subscaphium, triangulate, decurved, apex pointed; valve membranous, elongate, narrow, covered with broad, curved setae; costa sclerotized, deeply recurved, apex rounded or truncate, sparse hairlike setae dorsally and at apex; sacculus well developed, proximal half fused with valve, distal half free, elongate, broad, curved inward, longer than valve, apex with roughened surface; saccus V-shaped; aedeagus straight; vesica ovate, large bulbous lateral diverticula just above vesica base; adjacent to basal diverticulum a second bulbous diverticulum with an irregular sclerotized patch bearing elongate somewhat flattened cornutus; thumblike diverticulum opposite sclerotized patch; ventral cornutus at base of vesica, stout, elongate, pointed caudally. Female. As in male except:antenna filiform; forewing length 9.2–12.5 mm; medial area of forewing white, suffused with pale gray scales and less contrasting than in male. Genitalia (Fig. 40) – Papillae anales ovate, soft, fleshy, covered with numerous setae; venter of eighth segment covered with minute spicules; anterior apophyses fused with eighth sternite; posterior apophyses present; ventrolateral corners of eighth sternite produced into small, outwardly curved projections; ostium bursae crescent shaped, sclerotized plate bearing minute spicules; ventral to ostium bursae, base of ductus bursae rectangular and fused to eighth sternite, short membranous section of ductus bursae at juncture of appendix bursae and ductus bursae, ductus bursae striate and gradually enlarges into corpus bursae; appendix bursae emerges from ductus bursae just ventral to rectangular part of ductus bursae, consists of two sacs, one at junction of ductus bursae then a constriction and a second, enlarged, membranous sac; corpus bursae tear-drop shaped, covered internally with numerous thornlike signa.

Paectes asper is distributed from southern Florida and Bahamas to the Greater Antilles (except Puerto Rico), and the British Virgin Islands, U.S. Virgin Islands, and Dominica in the Lesser Antilles (Fig. 51). A specimen in the BMNH is labeled Costa Rica, St. Andrews I. This specimen was interpreted to be from San Andrés Island in the western Caribbean, which is now part of Colombia.

Paectes asper was in the series of specimens in the USNM collection identified as Paectes obrotunda. Specimens of Paectes asper can be confused with specimens of Paectes arcigera from the British Virgin Islands, U.S. Virgin Islands, and Dominica. Paectes asper is sympatric with Paectes arcigera on Guana Island, B.V.I., St. Croix, U.S.V.I., and Dominica. In Florida, Cuba, and the Dominican Republic, Paectes asper can be confused with Paectes nana.

The species name is derived from the combination of the Latin terms medius (middle) and albus (white) to refer to the white medial area of the male forewing.

Paectes medialba has been confused with Paectes longiformis in the USNM collection. It differs from Paectes longiformis by the more pronounced white medial area of the male forewing and its distribution in northwestern Argentina versus the northeastern Brazil distribution of Paectes longiformis. There are many differences in the male genitalia of Paectes medialba and Paectes longiformis. The free extension of the sacculus in Paectes longiformis is much longer than in Paectes medialba and is spiculate in Paectes medialba and non-spiculate in Paectes longiformis. The setae on the dorsal surface of the valve are wide, elongate, curved apically, and numerous in Paectes medialba whereas in Paectes longiformis they are hairlike, shorter, straight, and more sparse. In the female genitalia the lateral projections of the eighth sternite are more produced and sharply pointed in Paectes medialba (Fig. 41) than in Paectes longiformis (Fig. 38). The ductus bursae between its juncture with the appendix bursae and its entering the corpus bursae is tapered in Paectes medialba but straight in Paectes longiformis. The signa are more numerous in the corpus bursae of Paectes longiformis than in Paectes medialba.

The species name is derived from the Latin sinuo (bend), referring to the sinuate free saccular extension of the male genitalia.

The forewing is longer in Paectes sinuosa than in Paectes medialba. The postmedial line is double in Paectes sinuosa (Figs 22–25) and single in Paectes medialba (Figs 20–21). In the male genitalia the dorsal margin of the costa is slightly concave in Paectes sinuosa (Fig. 35) but greatly convex in Paectes medialba (Fig. 34). The free saccular extension is sinuate in Paectes sinuosa (Fig. 35) but straight in Paectes medialba (Fig. 34). At the base of the vesica there are two wide cornuti in Paectes sinuosa (Fig. 35) but only one in Paectes medialba (Fig. 34).

Known from the states of Goias and São Paulo, Brazil, the Chaco of northwestern Paraguay, and in the state of Tucuman, Argentina (Fig. 52).

Specimens from the São Paulo, Alambari, Brazil, were reared from Brazilian Peppertree (Schinus terebinthifolius). A specimen from Porto Feliz, São Paulo, Brazil, was reared from Lithraea molleoides (Vell.) Engl., Anacardiaceae.

Paectes sinuosa is described to differentiate the several species previously identified as Paectes obrotunda in the USNM collection.

Paectes sinuosa has two forms similar to those in Paectes nana. One form has bold markings of the antemedial and postmedial lines; the other form has faint antemedial and postmedial lines and an overall gray forewing. The male genitalia are identical in these two forms.

The species name is derived from the Latin tumeo (swell), referring to the swollen base of the free saccular extension in the male genitalia.

Forewing with a white medial area in Paectes tumida; in Paectes similis it consists of white-tipped gray scales, so the area is less contrasting than in Paectes tumida; in Paectes obrotunda medial area is mixed with gray, ferruginous, and a few cream-colored scales and also is less contrasting than in Paectes tumida. The postmedial line is faint and black in Paectes tumida; in Paectes similis it is black and well developed with a faint double line at the posterior margin; in Paectes obrotunda the postmedial line is ferruginous and double at the posterior margin and black and ferruginous where it curves toward the subapical black dash.

The male genitalia of Paectes tumida have elongate, curved setae on the dorsal surface of the valve, whereas in Paectes obrotunda and Paectes similis the valve has shorter, hairlike setae. The costal margin is convex in Paectes tumida, but straight in Paectes similis, and slightly concave in Paectes obrotunda. The free saccular extension is elongate and extends above the costa in Paectes obrotunda, but is shorter and does not extend above the costa in Paectes tumida and Paectes similis. In Paectes tumida, the base of free saccular extension is swollen and densely covered with spicules, but in Paectes obrotunda and Paectes similis the base is not swollen and without spicules.

Specimens have been collected from Villavicencio, Colombia, and from Guyana, Suriname, and French Guiana (Fig. 49).

Paectes tumida is described to differentiate the several species previously identified as Paectes obrotunda in the USNM collection.

Type locality: “Brazil” Holotype female. BMNH; photographs of adult and genitalia examined (Figs 44–47).

Since Paectes obrotunda is only known from the female holotype it can be compared to females of Paectes longiformis, Paectes sinuosa, and Paectes medialba, which are found in Brazil, Argentina, and Paraguay. Paectes obrotunda has a distinct antemedial line that extends from the posterior margin to the anal vein then curves around faint basal area toward Cu vein. In Paectes longiformis the antemedial vein is faint and not well developed. The forewing subapical, marginal dash is black and distinct in Paectes obrotunda, but ferruginous and faint in Paectes longiformis. There is a faint area of white scales proximal to the postmedial line in Paectes obrotunda, which is absent in Paectes longiformis. Paectes sinuosa is distinct from Paectes obrotunda in having the antemedial line heavily developed with black scales along the anal vein and suffused with black scales along the posterior margin. The forewing subapical, marginal dash is longer in Paectes sinuosa than in Paectes obrotunda. In Paectes medialba the postmedial line is double from posterior margin to approximately middle of forewing whereas in Paectes obrotunda it is single and faint. The forewing subapical, marginal dash is slightly longer and more robust in Paectes medialba than in Paectes obrotunda. In the female genitalia the eighth sternite is longer than wide with lateral margins produced in Paectes medialba but sternite in Paectes obrotunda is wider than long and the lateral margins are not produced.

Adult. Female. Head – antenna filiform; eyes large, globular; labial palp porrect. Thorax – prothorax light brown, anterior margin thin black line; forewing length 9.2 mm; a few white scales forming short dashes along costa, especially from postmedial band to just below apex; thin black antemedial line from posterior margin forming ventral border to faint basal spot; medial area of wing with some scattered white scales forming an indistinct area proximal to postmedial line; postmedial line black, faint at posterior margin becoming more distinct prior to subapical, marginal dash; black dash between veins R5 and M1 that extends to outer margin; apical spot white; terminal line a series of black, recurved lines between veins; fringe with white patches giving a checked appearance; hind wing with dark gray marginal band that extends to middle of wing with veins highlighted dark gray. Genitalia (Fig. 46) – Papillae anales crescent shaped, soft, fleshy, covered with numerous setae; ninth sternite probably covered with minute spicules; eighth sternite with no distal apical lateral projections, lateral margins straight; ostium bursae somewhat sclerotized, band-like with lateral apices narrowed; base of ductus bursae narrower than ostium bursae; remainder of genitalia unknown.

Known only from Brazil, with no specific locality.

Paectes obrotunda belongs in this species group because it shares with them the shape of the antemedial line, white medial area, white apical spot, and black marginal dash in the forewing. The female genitalia are different from those of the other species in this group and no other specimens from other groups examined during this study matched them, so Paectes obrotunda is only known from the holotype.

Paectes obrotunda has never been correctly identified in the literature. Hampson (1912) gave a wide distribution of Paectes obrotunda extending from throughout the Caribbean to Paraguay. The Caribbean distribution could refer to either Paectes asper, Paectes nana or Paectes arcigera, and the Paraguay record is probably Paectes sinuosa. Kimball (1965) recorded Paectes obrotunda from Florida and these specimens can be referred to either Paectes nana or Paectes asper. Franclemont and Todd (1983) listed Paectes obrotunda from North America, undoubtedly following Kimball (1965).

Due to the cryptic nature of this species complex, the remaining species of Neotropical Paectes are currently being revised. A number of specimens from Costa Rica that have been analyzed using DNA barcoding of CO1 and their respective host plants will be included. A phylogenetic analysis using morphological characters of the Neotropical species included in this and the next study will be discussed.
