Leucotrichia mutica Flint

Fig. 27

We found Leucotrichia mutica to be similar to that of L. melleopicta Mosely. The structure 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. mutica to 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 Rambala Jungle Lodge, 3.74 km SSE Rambala, 8.91627°N and 82.15469°W, 120 m, Malaise trap, February 6–12, 2017, E. Carlson, 6 males ; ibid., December 21–31, 6 males ; ibid., March 31–April 11, 2015, 2 males ; ibid., October 7–9, 2016, 17 males ; ibid., March 28, 2015, 1 male ; tributary of Quebrada Rambala, 2 nd footbridge, Rambala Jungle Lodge, 134 m, March 28, 2015, E. Carlson, 2 males .

Notes. As Leucotrichia mutica is similar to L. melleopicta , we have taken the opportunity to provide new drawings of L. melleopicta ( Fig. 28 ) from material collected in Quebrada Rambala at the following sites: near Rambala Jungle Lodge, 3.74 km Rambala, 8.91627°N and 82.15469°W, Malaise trap, October 7–9, 2016, E. Carlson, 38 males; ibid., December 21–31, 2016, 66 males ; ibid., February 6–12, 2017, 55 males, ibid., November 15–20, 36 males ; ibid., March 31–April 11, 2015, 50 males .
