Most similar to C.saxicolella
Male genitalia
Male genital key: Sacculus without a distinct posterior process; lateral margin of sacculus somewhat clubbed and indistinctly dentate; transtilla moderately broad, smooth; aedeagus with a linear bundle of cornuti in the vesica, without thorn cornuti.
One prong of the aedeagus has a large subapical tooth; the base of the same prong has a finely serrate keel; a smaller apical tooth on the other prong is variable (or not always visible) |
Female genitalia
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 only slightly deeper than lateral concavities, without distinct straight lateral margins
Very similar to C.saxicolella. 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 posterior margin. 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.
