Anastrepha cryptostrepha: Molineros et al. 1992: 40 [misidentification, see Tigrero 1998: 48].

Anastrepha amaryllis Tigrero 1998: 38 [description, wing, aculeus tip, Ecuador]; Norrbom et al. 1999b: 333 [classification]; Korytkowski 2004: 61 [in key].

Diagnosis. Anastrepha amaryllis differs from other species of Anastrepha except A. furcata , A. fuscata and A. robusta in having the aculeus strongly dorsally curved. We have not examined this species, but it appears to differ from the latter three species in having longer terminalia (oviscape 3.43 mm long, 0.71 times mesonotum length vs. no more than 3.0 mm long, 0.65 times mesonotum length in the other species). It also has a longer aculeus tip (0.47 mm, vs. less than 0.40 mm in the other three species). In wing pattern it more resembles A. robusta , with less extensive dark brown areas than in the other two species.

Description. Setae dark.

Thorax: Mesonotum 4.81 mm long. Scutum with dark brown band on posterior margin. Scutal setulae yellowish. Katepisternal seta short and weak.

Wing ( Fig. 18 ): Length 9.44 mm, 2.48 times as long as wide. Apex of vein R 1 at 0.55 wing length. Cell c 1.27 times as long as pterostigma; pterostigma 3.50 times as long as wide. Vein R 2+3 without sharp bends or undulations. Crossvein r-m at 0.65 distance from bm-cu to dm-cu on vein M. Vein M strongly curved apically; cell r 4+5 0.72 times as wide at apex as at level of dm-cu. Cell bcu with distal lobe moderately long, length of bcu 1.64 times as long as anterior margin. Wing pattern mostly orange and moderate brown. C-band with cells bc and c mostly yellowish; pterostigma mostly brown; cells r 1, br, and r 2+3 orange except posterior and distal margins partially narrowly brown. C-band and S-band broadly connected along vein R 4+5; hyaline area in cell br narrowly separated from vein R 4+5, ca. as long as distal orange area of cell; cell dm with basal hyaline area moderately large. Basal half of S-band mostly orange with brown margins, in radial cells and distally in cell dm, proximal margin in cell dm orange; more than posterior half of part in cell cu 1 brown; posterior margin with distinct incision in cell cu 1; distal section of band orange with brown margins, broad, at apex of vein R 2+3 0.91 times width of cell r 2+3, distinctly broadening in cell r 2+3, narrowly separated from apex of vein M. Hyaline basomarginal spot in cell r 1 triangular, with blunt apex, extended to R 4+5, its apex aligned proximal to crossvein r-m. V-band complete, mostly brown, broadly connected to S-band in cell r 2+3; proximal arm with medial orange area from apex of band to anterior fourth of dm-cu; proximal arm slender anteriorly, slightly broadening posteriorly, with short basal extension along wing margin, at level of vein M ca. 2 times as wide as distal arm and ca. as wide as hyaline area proximal to it in cells r 4+5 and dm; distal arm slender.

Male terminalia: Unknown.

Female terminalia: Oviscape 3.43 mm long, 0.71 times as long as mesonotum. Eversible membrane with only distal row of 6 scales large and curved. Aculeus dorsally curved, 2.59 mm long; shaft 0.09 mm wide at midlength; tip ( Figs. 143 , 164–165 ) 0.47 mm long, 0.08 mm wide, 5.88 times as long as wide (based on measurements in description, ca. 4.0 times as long as wide in figure), slightly expanded subbasally, then gradually tapered, nonserrate.

Distribution. Anastrepha amaryllis is known only from Ecuador.

Biology. The host plants and other aspects of the biology of this species other than date of capture of adults are unknown.

Type Data. Holotype female (Pontificia Universidad Católica, Quito), Ecuador: Napo: El Coca , Oct 1987, G. Onore and students, collected by net [not examined].

Comments. The description and measurements for this species, which we have not seen, are mostly taken from the original description and figures of Tigrero (1998) and additional measurements kindly provided by Ing. Tigrero. The measurments of the terminalia are those he provided in the description; the length/width ratio of the aculeus tip in Tigrero's fig. 82 is less than that based on the measurements.
