Multilure fruit fly trap baited with ammonium acetate & putrecine ( JEEC) ; 3 ♂ ♂, same data except 5-10.VI.2015 (1 each to JEEC, MHNJP, USNM) 1 ♂, same data except 1-21.X.2015 ( FSCA) ; 1 ♂ same data except 1-16.X.2015 ( MHNJP) .

Etymology: The specific epithet is a reference to the fruit flies of the genus Anastrepha that were the target of the trapping effort which resulted in the capture of this species.

Description. Mandibular plates punctured basally and along clypeus, lateral margins black. Impunctate roughly circular area present on border of each eye in front of ocelli; base of head tumid. Three basal antennal segments uniformly brown to reddish brown, fourth and fifth segments bright red basally, becoming dark red to piceus apically, red basal area relatively short on fourth segment, longer on fifth segment. Rostrum yellow brown, dark brown at apex of fourth segment.

Mesial ½ or more of anterior pronotal margin with impressed band of punctures; cicatrices impunctate, bordered anteriorly and posteriorly by punctures. Anterior margin of scutellum with narrow elongate dark brown fascia on each side of small pale mesial area; punctures of scutellum a little denser and smaller laterally and posteriorly, dorsal surface of post-frenal scutellar area shallowly impressed mesially. Coria dark brown basally and mesially, punctures dark brown throughout; most of embolium, veins, discal spot, and band connecting spot to posterior margin of coria, pale ( Fig. 1 ).

Abdominal tergites pale brown mesially, dark brown laterally; each connexival segment pale and impunctate mesially, bordered anteriorly and posteriorly by darker, punctate areas which become darker and more extensive on posterior segments. Abdominal urosternites pale brown with narrow marginal dark brown band laterally. Intersegmental sutures usually darker than surrounding area ( Fig. 2 ).

Male genitalia: middle half of ventral margin of pygophore strongly concave, concavity bordered on either side by small acute tooth ( Fig. 3 ); dorsal rim broadly concave with blunt projection on each side a little more than half way from meson to lateral margin ( Fig. 4 ). Genital cup processes large, broadly L-shaped, bordered dorsally by dorsal rim and medially by proctiger, lateral margins elevated ( Fig. 5 ). Floor of genital cup with distinct triangular setose projection on either side of proctiger. Dorsal face of proctiger quadrate in dorsal view, strongly convex, smooth with fine transverse striations, posterior face rough, setose. Parameres large, shank relatively simple, head complex, with lateral and mesial lobes; lateral lobes thinner, somewhat rectangular, curved anteriorly at apex, mesial lobes broad, broadly flattened mesially; head of parameres with anterior face minutely spiculate, posterior face relatively smooth; ( Fig. 8, 9 ). Phallotheca cylindrical, thick, curved dorsally ( Fig.10 ).

Female genitalia: gonocoxites 8 with disc elevated and sparingly punctured, posterior margin and band from posterior margin to meson of plates dark brown, posterior margin convexly angled. Gonocoxites 9 dark mesially, with cluster of setae on each side of meson. Apices of laterotergites 9 rounded, slightly surpassing band uniting laterotergites 8, the latter with acute spine apically.

Measurements:

Males (n = 7): total length 11.70–12.60; head length 1.50–1.70, width 2.50–2.60; preocular length 0.60–0.70, interocular width 1.20–1.40, interocellar width 0.60–0.70; length of antennal segments 1–5: 0.60–0.70, 1.30–1.60, 1.50–1.70, 2.80–3.40, 2.50–3.15; pronotum mesial length 2.50–2.80, width across humeri 6.30–6.70; scutellum length 4.50–4.75, width at widest point 3.40–4.10; distance from ostiole to lateral margin of metapleuron 1.80–2.10, length of ostiolar peritreme 1.25–1.6; mid-ventral length of abdominal segments 3‒7: 1.05–1.20, 0.80–0.90, 0.85– 0.90, 0.80–0.90, 1.70–1.90.

Female (n = 1): total length 12.50; head length 1.60, width 2.60; preocular length 0.70, interocular width 1.30, interocellar width 0.60; length of antennal segments 1‒3 (4 and 5 missing): 0.60, 1.50, 1.50; pronotum mesial length 2.70, width across humeri 6.50; scutellum length 4.70, width at widest point 3.80; distance from ostiole to lateral margin of metapleuron 2.15, length of ostiolar peritreme 1.50; mid-ventral length of abdominal segments 3‒7: 1.25, 0.90, 1.00, 1.10, 1.25.

Comments: The female gonocoxites 8 are artificially opened in the only specimen available of this sex ( Fig. 6 ). In a normal relaxed position, these plates would probably be contiguous, or nearly so, mesially.
