Leucotrichia mutica Flint, 1991

Fig. 12

Diagnosis.

This species is similar to L. melleopicta; both species display ranges that include Panama. As discussed under L. melleopicta, these species share similarities in the dorsal sclerite of the phallus apex, although this sclerite is much smaller than that seen in L. melleopicta (Fig. 12E), and the general shape of the inferior appendage. Leucotrichia mutica can be recognized separately from L. melleopicta by the tapering mesoventral process on segment VII (Fig. 12A), and by the prominent basal loop of the phallus (Fig. 12D, E).

Remarks.

Leucotrichia mutica in Thomson and Holzenthal (2015) was drawn from the holotype of the species from Colombia. This specimen had the lower half of the phallus missing from the medial ring-like structure downward, leaving only the apical portion. The species was fairly common in Panama, and we were able to identify it from the apical portion of the phallus, which in Leucotrichia is typically diagnostic, as well as the other genitalic features. Based on the fact that Thomson and Holzenthal’s original description was based on this single specimen from Colombia, we redrew it in Harris and Armitage (2019) to better reflect variation in the species and to include the basal portion of the phallus. The latter can be very useful in the diagnosis of the species.
