Walker & Funk, 2014
Fast-tinkling Trig
Anaxipha tinnulacita is a small swordtail described in 2014 from eastern North America. Males produce both calling songs and distinct courtship songs when in the presence of females. This exhibits substrate-borne through drumming , which is unique among studied in commonly occurring during calling songs.

Identification
Males can be distinguished from similar by courtship song characteristics: pattern of echeme delivery and syllable details differ from calling songs and from . Courtship song and drumming bout characteristics statistically similar to A. tinnulenta in some measurements, requiring careful acoustic analysis for separation. Drumming during calling songs occurs predominantly during the first 40% and last 20% of long echemes, a pattern common only in this species among the four studied.

Distribution
Eastern North America; documented from Pennsylvania.
Behavior
Males perform courtship songs when in the presence of females; these songs are structurally distinct from calling songs in pattern of echeme delivery and syllable details. Males exhibit drumming (substrate-borne ) during courtship singing and variably during calling songs. Drumming is performed by using the sclerotized portion of the to impact the substrate. Unlike studied, drumming during calling songs is common in this and occurs predominantly during the first 40% and last 20% of long echemes.
