Confluens is a genus of caddisflies belonging to the family Oeconesidae. [1] The genus was described by Keith Arthur John Wise in 1962, after noticing differences in two species previously placed within the genus Pycnocentrodes . [2] Both species of Confluens are endemic to New Zealand.
Keith Arthur John Wise originally described the genus in 1962, naming Confluens hamiltoni as the type species. [2] Both of the species he placed within the genus, C. hamiltoni and C. olingoides , had been identified in 1924 by Robert John Tillyard as species within the genus Pycnocentrodes. [3] [2]
Phylogenetic analysis indicates that Confluens forms a clade with the genera Alloecentrella , Beraeoptera , Olinga , Pycnocentria and Pycnocentrodes . [4]
Wise's original text (the type description) reads as follows:
Ocelli absent; ♂ frons with a small hole on each side. Maxillary palpi, ♂, membranous, apparently two-jointed with transverse suture, as in Pycnocentrodes, but appearing as one in internal view; no brush of hairs from base. Wings, ♂ (fig. 1); anterior with a callosity at base, discoidal cell exceedingly narrow and long but abnormal apically, R2+3 and R4+5 rejoin to form a single stem from which apical forks 1 and 2 both arise, apical forks 1, 2, 3 and 5 present; posterior with R2+3 missing or only apical remnant present (as figured), discoidal cell open above, discoidal cross-vein and apical forks 1, 2 and 5 present. Wings, ♀, anterior as Pycnocentrodes, discoidal cell normal, apical forks 1, 2, 3 and 5 present ; posterior as Pycnocentria, short discoidal cell present. Spurs 2. 2. 4. [2]
Wise notes that the fusion of R2+3 and R4+5 is a distinguishing feature of this genus. [2]
The genus is found in New Zealand. [1]
