Diagnosis.

This is a distinctive new species in the genus, belonging to the Atopsyche longipennis Ulmer group of the subgenus Atopsaura . Atopsyche galharada sp. n. resembles Atopsyche ayahuaca Schmid and Atopsyche plancki Marlier in the absence of filipods and in the simple phallotheca. The new species can be distinguished from the others by the broader parapod with 2 carinas bearing tooth-like processes. The new species and Atopsyche plancki are similar in the short and broad first article of the inferior appendage, with an apical process, but in the new species this process is longer and the second article of the inferior appendage is broad in ventral view, and slightly hooked in lateral view. Also, Atopsyche galharada has the proctiger with a broad lateral sclerotized projection, and the phallotheca posteriorly divided into long, paired flangelike processes, broadest subapically, in dorsal view.

Male.

Forewing length 6.5-7.5 mm (n=23). Overall body color brown; antennal scape light brown, with long stramineous setae, pedicel brown, basal flagellomeres yellow, apical flagellomeres brown; setae of palps dark brown; frons and vertex of head with long, erect stramineous setae; legs yellowish brown, coxae of all legs darker brown. Forewings brown; erect setae on veins forming irregular pattern of alternate dark brown and yellow setae, with dark brown setae along costal margin; apex of wing with fringe of alternating patches of dark brown and yellow setae. Forewing venation complete (Fig. 6A); R1 branched; stem of fork I equal to its length; fork II long, sessile; stem of fork III equal in length to stem of fork I; fork IV long, sessile; stem of M slightly curved between m-cu crossvein and first fork of M; fork V long, narrow; Cu2 long, converging near fused anal veins, crossvein near apex forming small cell on posterior margin of wing; apex of fused anal veins very short. Hind wing (Fig. 6B) with Sc and R1 fused apically; forks I, III, and V present, the first with a short stem, the last long with a short stem, stem of fork III equal to its length; forks II and IV absent; M3+4 reaching wing margin; Cu2 long and almost straight; 1A long and sinuate. Nygmas indistinct in both wings. Sternum V with pair of small rounded glands on anterolateral margins, with a keel-like projection (Fig. 9). Sterna VI and VII with prominent spine-like ventral processes on posteromesal margins.

Male genitalia.

Segment IX, in lateral view, long (Fig. 3A). Parapod broad basally, narrow apically, with two carinas bearing tooth-like processes along dorsolateral edges and short, stout setae (Figs 3A, 3B). Filipod absent (Fig. 3A). Preanal appendage short, rounded, setose (Figs 3A, 3B). Inferior appendage, first article short, uniformly broad, with narrow apical process, nearly equaling second article in length (Figs 3A, 3C); second article large, bulging basally and downturned apically, in ventral view, broad (Figs 3A, 3C). Proctiger, in lateral view, uniformly wide, with broad lateral sclerotized projection and truncate apical margin, covered with minute setae, apicodorsal margin with long setae (Fig. 3A). Phallic apparatus simple (Figs 3D, 3E); phallotheca broadly rounded basally, not articulating with inferior appendages (Fig. 3D); posteriorly di vided into long, paired flangelike processes, broadest subapically, in dorsal view (Fig. 3E); aedeagus an elongate, stout, spine-like structure, with strong basal loop (Fig. 3D).
