Additional description. Male abdomen: Mostly brown. Tergites 3–5 medially, and sometimes syntergite 1+2 posteromedially, with aligned narrow yellow spots or more complete marks forming vitta, marks sometimes minute or rarely absent on tergites 3–4; posterior margin of syntergite 1+2 and tergites 3–4 sometimes with posterior margin also narrowly yellow on medial 1/3–2/3. Tergite 5 also with at least posterior margin yellow, narrowing laterally, or more extensively yellow (at least anterior and lateral margins brown).

Female abdomen ( Fig. 26 ): Mostly brown. Tergites 3–5 medially with aligned narrow yellow spots or more complete marks forming vitta, marks sometimes minute or rarely absent on tergites 3–4. Tergite 6 mostly orange except laterally.

Female terminalia (measurements, n=2): oviscape orange ( Fig. 26 ) stout, 1.52 mm long. Aculeus ( Fig. 36 ) 1.14–1.26 mm long, 0.19–0.20 mm wide, tip ( Fig. 37 ) 0.28–0.29 mm long, 0.12–0.14 mm wide, with 2 pairs of small steps or lobes at distal 0.65–0.68 and subapically. 3 spermathecae subspherical, with short base.

Comments. Previous records and description of this species were based only on males. The female abdomen and terminalia are described above. The aculeus tip has two pairs of small lobes or notches, differing from other species of the genus, in which the margin is serrate. The serrate tip is another synapomorphy for those species, further supporting the hypothesis that C. obliquus is the sister group of the remaining species of Cryptodacus ( Norrbom 1994) . The number of spermathecae in C. obliquus (3), also differs from the other species of Cryptodacus for which this character has been studied. This number also varies between the two species groups of the related genus Rhagoletotrypeta ( Norrbom 1994) .
