Rhyacophila nigrocephala Iwata 1927
No full textRhyacophila nigrocephala species group Diagnosis (modified from Schmid 1970) The species group can be diagnosed by the combination of following characters. In the male, segment IX is usually long, with the apicodorsal lobe fused with the preanal appendages into a complex, covering the other portion of the male genitalia. The anal sclerites are fused, with the apex slightly incised mesally and curved upwards, its root is large and curved upwards. The tergal band is slender, flattened dorsoventrally, with the apex sagittal, and has been termed as the sagittal appendage by Ross (1956). The apical band is with two lateral arms articulating, with anal sclerites above and with the tergal band beneath. The phallic apparatus is elongate and cylindrical; the aedeagus with the apex is thin; the parameres, if present, are slender. Schmid (1970) recognized two sub-groups, the R. manuleata subgroup and the R. nigrocephala sub-group.Published as part of Sun, Changhai, 2017, Two new species of the Rhyacophila nigrocephala species group from China (Insecta, Trichoptera, Rhyacophilidae), pp. 1-10 in European Journal of Taxonomy 300 on page 3, DOI: 10.5852/ejt.2017.300, http://zenodo.org/record/382578

Apatidelia Mosely 1942
No full textGenus Apatidelia Mosely, 1942 Apatidelia Mosely, 1942: 343 (type species: Apatidelia martynovi Mosely, 1942, by original designation). Diagnosis Adult Body size moderately small, length about 5.0–9.0 mm; body color dark-brown. Cephalic setal warts similar to those of Apatania, with a pair of lateral ocelli. Fore wings transparent, with a patch of dense hairs near the apex of vein Sc; vein R with a row of close, short, black hairs from the apex to the sub-base (Mosely 1942); FI–III and FV presented in both fore and hind wings; discoidal cells in the fore wings are closed but are open in the hind wings. Spurs 1, 2, 4. Abdominal sternum V with a lateral process on each side in male, by which males are easily separated from any other genus of the tribe Apataniini. However, due to the absence of such structures, females of the genus must be identified by a short apical vulvar lobe of sternum VIII and a roof-shaped, slightly sclerotized segment X. The vulvar lobes of sternum VIII in female Apatania Kolenati, 1848 are usually slender, thumb-like or slender, rectangular.Published as part of Xie, Yue, Wang, Beixin & Sun, Changhai, 2017, Associations and a new species of the genus Apatidelia (Trichoptera, Apataniidae) from China, pp. 1-20 in European Journal of Taxonomy 333 on page 4, DOI: 10.5852/ejt.2017.333, http://zenodo.org/record/382981
Rhyacophila voluta Sun 2017, sp. nov.
No full textRhyacophila voluta sp. nov. urn:lsid:zoobank.org:act: DF10323C-1202-4D75-8CB2-9C2C5B87A026 Fig. 2 Diagnosis The new species belongs to the R. nigrocephala sub-group, and is similar to R. pentagona Malicky & Sun, 2002 from Yunnan, China, in the male genitalia, but differs in: (1) the inferior appendages of about the same length as the complex of the preanal appendages and the apicodorsal lobe of segment IX (obviously shorter than the complex in R. pentagona); (2) the basal segments of the inferior appendages in lateral view are somewhat rectangular and in ventral view with their bases fused (pentagonal in R. pentagona, and their bases not fused obviously); (3) the apical segments of the inferior appendages with each distal margin slightly concave (straight in R. pentagona). Etymology The species epithet comes from the Latin word “ volutus ”, meaning “having been curled”, in reference to the subapical margin of the complex of the preanal appendages and the apicodorsal lobe of segment X extending upward into a curled lamella.

Apicodorsal lobe of segment IX and preanal appendages fused into complex (com.), in lateral view it curved downward at middle, with broad base and thin apex, subapex with dorsal margin extended upward to form lamella; in dorsal view complex with the two lateral margins parallel to each other, and apex triangular, the lamella curled. Anal sclerites (as.) large, with base fused into complex of apicodorsal lobe and preanal appendages, in lateral view somewhat triangular, in dorsal view its apex incised.

Basal segment of each inferior appendage (bia.) in lateral view somewhat rectangular, base slightly broader than apex in lateral view, in ventral view bases fused mesally; apical segment of each inferior appendage (aia.) in lateral view trapezoidal, with distal margin shallowly concave, in ventral view somewhat triangular. Phallic apparatus simple: phallotheca (pht.) tubular in lateral view and trapezoidal in ventral view, endotheca (end.) membranous, aedeagus (aed.) tubular, with apex narrowed suddenly.
