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. |
