Identification
Members of Mystacides can be distinguished from other Leptoceridae by the combination of a reduced maxillary palp (5-segmented in males, 3-segmented in females) and specific wing venation patterns. -level identification within Mystacides requires examination of male genitalia, particularly the structure of the inferior appendages and phallic apparatus. M. alafimbriatus is distinguished from by details of the male genitalia, including the shape and setation of the inferior appendages.
Distribution
North America; Nearctic region. Specific locality records are sparse in available sources.

Taxonomic History
Described by Hill-Griffin in 1912. The Mystacides was revised by Morse (1975), who provided keys to North American . The specific epithet 'alafimbriatus' refers to fringed wings ('ala' = wing, 'fimbriatus' = fringed).
Larval Biology
Larvae of Mystacides are generally predatory or , constructing portable cases from plant material or sand. Larval identification to species is difficult and rarely confirmed; specific larval associations for M. alafimbriatus have not been documented in available sources.
