Toxotrypana curvicauda, Gerstaecker, 1860

Key to the species of the curvicauda View in CoL group of Anastrepha

1.- Pleuron largely yellow with sparse dark brown markings; scutum mostly yellow with well differentiated submedial stripes, always separated from the spot on scutal posterior margin; black stripe on anatergite always absent.................... 2

1’.- Pleuron largely black or dark brown, with few yellow or whitish streaks; scutum mostly dark brown, without distinguishable submedial stripes; tergites and sternites of abdomen extensively dark brown; if scutum is mainly yellow with noticeable stripes, then submedial stripes are always connected posteriorly to brown marking of the posterior scutum; anatergite stripe present.... 4

2.- Abdominal tergites entirely yellow to orange; presutural sublateral patch usually complete and large, widely attached to notopleural spot; scutum posterior mark extending up to about one-half the postsutural scutum length...................................................................... A. curvicauda flavigaster Hernández-Ortiz , new subspecies

2’.- Abdominal tergites bicolored black to dark-brown, with posterior margins yellow, other characters variable.............. 3

3.- Presutural sublateral mark often reduced anteriorly, weakly attached to notopleural mark posteriorly; long submedial stripes extending beyond level of supraalars, down close the level of postalar setae; lateral bases of scutellum black spotted......................................................................... A. curvicauda (Gerstaecker) View in CoL , sensu stricto

3’.- Presutural sublateral spot always compact ovoid; submedial stripes relatively short, separated anteriorly or weakly connected to sublateral stripes, projecting slightly below transverse suture, reaching approximately to level of supraalar setae; notopleuron yellow or black spotted; abdominal tergites II-V brown or sometimes yellow at posterior apical margins; lateral bases of scutellum yellow, without basal black markings................................. A. nigrotaenia (Enderlein) [in part]

4.- Head, mesonotum and pleuron mostly yellow; submedial stripes long and well differentiated, unbroken from anterior margin to join posteriorly with black mark on posterior margin of scutum; diagonal stripe of anatergite usually present........... 5

4’.- Head, mesonotum, pleuron and abdominal tergites predominantly dark brown to black; scutum dark brown to black devoid of distinct submedial stripes, or sometimes with thin yellow lines starting from inner edge of postpronotal lobe, bending outwards at crossing of transverse suture extending to the sublateral margin of scutum; two short yellow stripes along the line of dorsocentral setae; scutellum mostly blackish, with occasional pale yellow disc colouration................................................................................................ A. nigrotaenia (Enderlein) [in part]

5.- Submedial stripes merging into a single stalk, shortly before joining to scutal mark on posterior margin; postsutural sublateral stripes often separated laterally from posterior scutal mark; female aculeus tip with numerous small teeth (> 40 teeth per side), shape of tip variable................................................................................... 6

5’.- Submedial stripes often weak over transverse suture, typically attached independently to the spot on posterior margin of scutum; postsutural sublateral stripes connected laterally to scutal posterior mark; female aculeus tip tapering gradually to apex, toothless or only with few minute serrations (≤ 20 teeth per side) confined to approximately 1/7 of tip length........ 7

6.- Postsutural lateral stripe absent; postsutural sublateral stripe always separated inferiorly from spot on posterior scutum; presutural sublateral spot split into two parts, connected anteriorly and posteriorly to dark markings of notopleuron; oviscape 23.4-35.8 mm long (X= 28.4 mm); aculeus tip tapering gradually to the apex, 0.34-0.37 mm long, with apical section serrated occupying 0.13-0.17 mm ............................................ A. magnifica Hernández-Ortiz , new species

6’.- Postsutural lateral stripe present; postsutural sublateral stripe posteriorly always connected to spot of posterior scutum; presutural spot compact and large (not partitioned); oviscape 7.3-9.7 mm long; aculeus tip triangular-shaped, 0.25-0.30 mm long, with a serrate section occupying 0.19-0.22 mm of length....................... A. ligiae Martínez-Alava & Serna

7.- Submedial stripes complete along the entire length, reaching down the blackspot of the scutum; oviscape length 13.4 mm; aculeus tip 0.38 mm long, 0.10 mm of basal width (Ac-ratio= 3.8x), with only few minute denticles (only visible under high magnification), scarcely covering 0.05 mm of apical end.................................... A. littoralis (Blanchard) View in CoL

7’.- Submedial stripes faint on transverse suture, and close to posterior margin of scutum; oviscape length 23.7-25.5 mm; aculeus tip 0.38 mm long, 0.11 mm basal width (Ac-ratio= 3.5x), non-serrate along entire tip length ( Ecuador)...................................................................................................
