B63587AFE441FF8CFF34FB30FC0255A8.taxon	discussion	Remarks. Adults of T. styloryncha are easily distinguished from other Nearctic Trichomyia by the shape of the genitalia, particularly the spatulate aedeagus and beaked gonostyli in the male, and the shape of the subgenital plate and spermathecae in the female. The Costa Rican species Trichomyia intricata Quate, 1996 is nearly indistinguishable from T. styloryncha according to Quate’s description and illustration; however, an examination of the paratype of T. intricata revealed the following character states that clearly differ from those of T. styloryncha: aedeagus with median filamentous projection; gonostyli tapered, not inflated apically, not strongly curved; lobes of gonocoxites tapered from base to apex.	en	Curler, Gregory R., Moulton, John K.

B63587AFE446FF85FF34FF22FED155A8.taxon	discussion	Remarks. Threticus thelyceratus is one of two Nearctic species of Threticus. It is sympatric with, but easily separable from T. bicolor (Banks) by the shape of the parameres, particularly the elongate, filamentous paramere in the male and the shape of the subgenital plate with protuberances and genital duct with hornshaped dorsal projections in the female. As illustrated by Wagner (1984), the male terminalia of Threticus species exhibits mirrored symmetry in some specimens, and can appear different in some specimens due to the aedeagus and parameres being retracted into the abdomen. Both of the aforementioned conditions were observed in T. thelyceratus, but most specimens died with the aedeagus and parameres fully exerted. Larvae of this species were collected from in between moist decaying leaves, which were lying along the margin of a first order stream.	en	Curler, Gregory R., Moulton, John K.
