Insecta Mundi 2019 2019-05-31 707 707 1 54 6PVPC Flint Flint 1991 [192,547,478,503] Insecta Hydroptilidae Leucotrichia Animalia Trichoptera 21 20 Arthropoda species mutica   Fig. 27 We found  Leucotrichia muticato be similar to that of  L. melleopictaMosely. Thestructure of the inferior appendages, which appeared to be fused ventrally and the details of the phallus seemed to vary from the figures in Thomson and Holzenthal (2015). We found  L. muticato be most easily recognized by the setose basal loop of the phallus. Thomson and Holzenthal (2015)mentions in their revision that the posterior portion of the phallus is missing from  L. mutica, and that the description was based on a unique holotype. The species was fairly common in our collections from Quebrada Rambala.   Material examined.   Panama, Bocas del Toro Province, Quebrada Rambala, near RambalaJungle Lodge,  3.74 kmSSE Rambala, 8.91627°Nand 82.15469°W,  120 m, Malaise trap,  February 6–12, 2017, E.
