Female genitalia
AP small narrow elongate slightly hairy pads bearing PA from lateral margins. PA ~2xOP, reaching anterior margin of A8 with ovipositor extended. Moderate extension at A8/9 ISM. A8 dorsal plate weakly sclerotised, hyaline at lateral margins; posterior margin with a central ~V-shaped notch and rounded posterolateral angles; anterior margin produced into a short midline point. OP transverse; AA from anterolateral angles ~1xOP; PM sparsely setose, with central incision to ostium and shallower lateral concavities; AM shallowly concave; ostium with a shallow-V-shaped ventral margin. Antrum sclerotised, extends just anterior to AM where it narrows somewhat to junction with DB. DB long with a single loose coil in posterior half and ~4 tight coils in anterior half; fairly constant diameter; junction with CB distinct. Sclerotisations: linear from AM through posterior ½; circumferential spiculate from junction with antrum for posterior ~⅓. DS enters at anterior end of linear sclerotisation. CB spherical with a small thorn and an elongate scobinate patch. Female genital key: Corpus bursae with both a thorn signum and a linear spiculate patch; extensive bilinear spiculation of the posterior portion of the ductus bursae with a tail extending anteriorly; posterior margin of the ostial plate with lateral excavations; ostial incision much deeper than lateral concavities, with distinct straight lateral margins
Very similar to C.sternipennella.The key difference described in MBGBI3 is that the ostium is U-shaped in C.saxicolella and V-shaped in C.sternipennella. The shape is formed by the ventral margin of the ostium together with the lateral margins of the ostial incision in the PM. The critical distinction is that this incision is deeper in C.saxicolella such that sides of the ostial incision are distinctly visible posterior to the ostium and the ostial incision is much deeper than the lateral excavations. In C.sternipennella there is hardly any distinct lateral margin to the ostial incision separable from the ventral margin of the ostium, such that the depth of the ostial incision is not much deeper than that of the lateral concavities.
