<em>Anastrepha suspensa</em>

Anastrepha suspensa

Caribbean fruit fly
Previous scientific names: Trypeta suspensa, Acrotoxa suspensa, Trypeta (Acrotoxa) suspensa, Anastrepha longimacula, Anastrepha unipuncta


Morphological – adult

This species is in the fraterculus-group.

Features include:

  • frons without brown markings except ocellar tubercle
  • mesonotum with three pale postsutural vittae
  • scutum posteriorly with only single medial brown spot on scuto-scutellar suture (spot usually large and distinct)
  • scutellum entirely yellow or with dark markings only on extreme base of disk
  • subscutellum entirely yellow to orange, or yellow to red-brown medially, dark brown laterally
  • mediotergite yellow to red-brown medially, dark brown laterally
  • wing with typical Anastrepha pattern (S-band complete or at most interrupted at crossvein r-m, C-band and at least proximal arm of V-band present), C-band and S-band separated or connected, V-band proximal arm as dark as apical half of S-band, not connected anteriorly to S-band (usually) or connected anteriorly to S-band along vein R4+5 or in cell r2+3, V-band distal arm complete
  • abdominal tergites without brown markings
  • aculeus length 1.40 – 1.60 mm
  • aculeus tip length 0.19 – 0.23 mm
  • aculeus tip width: 0.10 – 0.13 mm
  • lateral margins of aculeus tip not curved dorsally.

There are no fully diagnostic restriction enzymes for A. ludens.

HinfI will distinguish the group A. ludens and A. suspensa, species which cannot be distinguished from each other.

Similar species

Anastrepha suspensa possesses external characters that closely resemble those of A. fraterculus and A. obliqua; therefore, the separation of these three species is sometimes difficult.

One of the most obvious distinguishing marks in A. suspensa is the presence (except in some specimens from Jamaica) of a dark spot at the junction of the scutum and scutellum. This spot is sometimes present in A. fraterculus but is usually smaller, and it is absent in A. obliqua.

The apical part of the S band in A. suspensa is relatively wide compared with that in the other two species, and its inner margin is less concave. It covers the apex of vein M or ends immediately anterior to it, whereas in the other two species it normally ends well anterior to the apex of vein M, or its inner margin is strongly concave.

As in the identification of other species of Anastrepha, the shape of the aculeus tip is important. In A. suspensa, as in A. fraterculus, the serrations occupy no more than three-fifths of the tip, whereas those in A. obliqua occupy at least two-thirds; this character is variable and should be used with care (Foote et al. 1993).
