This new species belongs to the
A
. (
Atopsyche
)
bolivari
Group as indicated by the second article of the inferior appendage constricted at the middle, “bean-shaped” (
sensu
Ross & King 1952
).

in the shape of the ventral projection of the parapod, but it can be distinguished by the additional projection at the apex. This new species has conspicuous inferior appendages, each with the first article short, tall, and broad, and the second article extremely long, slender, downcurved, and slightly constricted at the middle; and parapods each have a ventromesal projection.
Description.
Length of each forewing
7.97 mm
(n = 1). Overall body color yellowish brown. Frons and vertex of head with brown setae. Antennal scapes with some long brown setae; pedicels light brown, basal flagellomeres light brown, apical flagellomeres yellowish. Maxillary palp segments 1 and 2 with brown setae. Dorsum of thorax with long brown setae. Overall color of wings brown; erect setae of veins dark brown. Forewing venation complete (
Fig. 1A
); R1 branched slightly beyond middle of wing, discoidal cell originating at middle. Hind wings each with R1 merging apically with Sc; 1A arising from Cu2 basally and merging with Cu2 apically (
Fig. 1B
). Sterna VI and VII each with posteromesal projection; anterior projection slightly longer than sternum VI, and posterior projection shorter than anterior, slightly shorter than sternum VII.
Genitalia. Segment IX longitudinally short, with anterior margin convex and posterior margin nearly straight in lateral view (
Fig. 4A
). Proctiger rectangular, constricted slightly at middle, vertically taller posteriorly, with truncate apex in lateral view. Parapods broad, each with 3 projections, first one dorsal at mid length with acute point upcurved, second at apex with acute point upcurved, and third ventrally with acute point upcurved in lateral view (
Fig. 4A
); slender, with three projections, serrate margin in dorsal view (
Fig. 4A
). Filipods about as long as parapods in lateral and dorsal views (
Figs. 4A, 4D
). Preanal appendages short and rounded in lateral and dorsal views (
Figs. 4A, 4D
). Inferior appendages, each with first article short, tall, and wide, with mesoventral projection in lateral and ventral views (
Figs. 4A, 4B
); second article long, slender, almost twice as long as first, constricted at middle in lateral and ventral views (
Figs. 4A, 4B
). Phallic apparatus complex (
Figs. 4C, 4E
): Phallotheca round basally, with dorsal process projecting posterad, broad subapically, acute and downcurved apically in lateral view (
Fig. 4C
); pair of “beaks” slender apically in dorsal view (
Fig. 4E
), with acute and upcurved apices in lateral view (
Fig. 4C
); aedeagus short and upcurved in lateral view (
Fig. 4C
).
