Ordo: Trichoptera
Familia: Hydroptilidae
Genus: Caledonotrichia
Name
Caledonotrichia charadra Kelley – Wikispecies link – Pensoft Profile
- Caledonotrichia charadra Kelley (1989: 194).
Revised diagnosis
Like Caledonotrichia capensis males have scale patches on both fore- and hind wings (Figs 9–10), a feature that distinguishes it from Caledonotrichia minor and Caledonotrichia ouinnica, both of which have scale patches on the forewings only; in the genitalia (Figs 54–56) the triangular shape of ventral lobes of the gonopods of Caledonotrichia charadra closely resembles the arrangement in Caledonotrichia capensis sp. n. and Caledonotrichia vexilla sp. n. but in Caledonotrichia charadra the dorsal lobes are quadrilateral, rather than elongate rectangular or subrectangular as in those two species, and the paramere associated with the phallic apparatus is more gently curved.
Additional information, male
Male head rounded as in Caledonotrichia capensis. Male antennae with 24–26 flagellomeres; flagellomeres elongate rectangular. Male maxillary palps as for Caledonotrichia capensis. Male forewing length, 1.5–1.9 mm (n=10). Fore- and hind wings both bear rectangular patch of black scales proximally (Figs 9–10), although these may be shed or lost due to abrasion.
Remarks
Several features noted on examination of the type specimen of Caledonotrichia charadra that were not mentioned by Kelley (1989)[1] were scales on wings and the subapical irregularity on the ventral processes, that gives the apex a hooked appearance when seen in lateral view. In addition, while the type specimen has scales on the forewing only, we are assuming that the scales were lost from the hind wing as, in other respects, the more recently collected specimens conform to the type but have scales on both wings.
