Anastrepha hermosa Norrbom

Recognition
Anastrepha hermosa belongs to the schausi species group, which differs from other species of Anastrepha in having minute spines on the glans of the male, the facial carina weak, the lateral surstylus acute, its lateral margin usually slightly concave, and the male face and/or abdomen with white or brown markings. Anastrepha hermosa differs from all other species of Anastrepha except A. fernandezi and A. schausi by the shape of the face, particularly its angulate lower margin. It differs from both of these species in having narrower nonmicrotrichose stripes on the scutum and in male facial and abdominal color patterns. The male of A. hermosa has a white band along the ventral margin of the face, whereas A. fernandezi has only a white spot on the facial ridge and A. schausi has broad black and white bands. The medial white stripe on the male abdomen is shorter than in A. fernandezi and the dark brown abdominal markings are absent in A. schausi. The abdominal microtrichia pattern is also a useful diagnostic character. The female (so far unknown) probably has the face similarly shaped as the male, or at least with the carina weak. Estimating from the length of the phallus, the female oviscape is probably about 4.5 mm long. Anastrepha scobinae Stone, hastata Stone, and tubifera (Walker), which are known only from females, have wing patterns similar to hermosa and terminalia of corresponding length, but they all have well developed facial carinae and are doubtfully conspecific. A. tubifera also has vein M much more strongly curved apically, and it and A. hastata also have the scutum entirely microtrichose.

Description

Adult: Mostly yellow brown to orange; setae blackish; setulae orange.

Head: Orange except ocellar tubercle and at least in male facial ridge and entire lower margin of face creamy white; face microtrichose, short, ventral part expanded laterally, in anteroventral view lower margin of face and facial ridge meeting at about 90o angle, carina weak; gena narrow, height 0.13-0.15 longest diameter of eye; posterior orbital seta well developed; ocellar seta weak; first flagellomere moderately long but nearly reaching lower facial margin, length about 0.78-0.80 height of face.
Thorax: Mesonotum 3.14-3.62 mm long; scutum microtrichose except broad stripes lateral to acrostichal setae and mesal to dorsocentral setae, from anterior to posterior margin; scutum mostly orange, with narrow pale medial stripe and white postsutural lateral vittae; scutellum microtrichose; katepisternal setae strong, about as long as outer vertical seta; subscutellum and mediotergite entirely orange; pleural color pattern indistinct.

Wing: Length 8.14-8.72 mm. With typical Anastrepha pattern, bands light to moderate brown, not connected; V-band complete; M weakly curved apically, well separated from apex of S-band.
Male abdomen: Syntergite 1+2 mostly orange, with lateral dark brown stripes on apical half; tergites 3 and 4 with broad lateral dark brown stripes; tergite 5 entirely dark brown; syntergite 1+2 and tergite 3 and 4 with median stripe of dense microtrichia, nearly corresponding with light colored area, producing silvery appearance at certain angles. Terminalia with outer surstylus moderately long, flat, acute, with outer margin nearly straight, inner margin slightly concave; phallus 6.28 mm long, 2.00 times as long as mesonotum; glans 0.60 mm long, with numerous minute apical spines, acrophallus expanded and involuted apically; proctiger uncreased laterally, weakly sclerotized.
Female: Unknown.
Immature stages: Unknown.
