038187CBAD32C949E045FE16FE16F827.taxon	diagnosis	Diagnosis This new species belongs to the group of Oxyethira caledoniensis. It is similar to O. houailou Wells & Johanson, 2015 by the presence of strong sclerotized margins of the inferior appendages, each one bearing one seta in the mesal region as seen in ventral view; and by the general shape of the phallus apex, with a subdistal spine curved to the left in dorsal view. Oxyethira (Trichoglene) hamus sp. nov. is recognized by the hook-shaped apex of the long inferior appendages in lateral view (short and with pointed apex in O. houailou) and by the posterior margin of segment IX having a trilobed appearance in ventral view (forming a subtriangular projection in O. houailou).	en	Cavalcante, Bruna Maria Silva, Johanson, Kjell Arne (2022): Three new species of Oxyethira Eaton, 1873 (Trichoptera: Hydroptilidae) from New Caledonia.

038187CBAD34C94FE06EFEF7FC70F933.taxon	diagnosis	Diagnosis Oxyethira (Trichoglene) rectangulata sp. nov. belongs to the group of Oxyethira spinifera. It is similar to O. tiwaka Wells & Johanson, 2015 by the quadrangular shape of segment IX in ventral view, and in lateral view by the inferior appendages being divided into a dorsal part forming a hump and a ventral part forming a pointed projection. This species can be recognized by the rectangular shape of the inferior appendages in dorsal and ventral views, which are totally fused, bearing two pairs of small setae on the inner face (in O. tiwaka these appendages are much smaller and the ventral part forms a quadrate-shaped sclerotized projection in ventral view); by the shape of the subgenital process in lateral view, which is thinner and almost straight in O. rectangulata sp. nov., and thicker, C-shaped in O. tiwaka.	en	Cavalcante, Bruna Maria Silva, Johanson, Kjell Arne (2022): Three new species of Oxyethira Eaton, 1873 (Trichoptera: Hydroptilidae) from New Caledonia.

038187CBAD36C94DE049FEF7FD02F998.taxon	diagnosis	Diagnosis Based on general similarities, Oxyethira (Trichoglene) spiralis sp. nov. is tentatively placed in the group of Oxyethira caledoniensis. It is similar to O. caledoniensis Kelley, 1989 by the shape of segment IX in ventral and lateral views, with the anterior margin only slightly produced anteriorly and by the shape of the apparently fused inferior appendages. In O. caledoniensis the inferior appendages are widely separated and form bilobed sclerotized structures that are absent in O. spiralis sp. nov. The new species can be recognized in lateral view by the subquadrate shape of the inferior appendages, by the strongly curvilinear shape of the subgenital process in dorsal and lateral views, and by the long process spiralling around the ejaculatory duct at the phallus apex.	en	Cavalcante, Bruna Maria Silva, Johanson, Kjell Arne (2022): Three new species of Oxyethira Eaton, 1873 (Trichoptera: Hydroptilidae) from New Caledonia.
