Tagalopsyche Banks

Type species: Tagalopsyche sisyroides Banks, 1913 , monotypic.

Tagalopsyche Banks, 1913: 177 ; 1916: 213. — Ulmer 1930: 404, 468, 492 [diagnosis, key]; 1951: 411, 417; 1955: 508, 511 [larva, pupa]. — Kimmins 1963a: 150.

Adult ( Figs. 1–2 ). Length of forewing: male 5.5–8.5 mm, female 5.5–9.0 mm. Eye size normal to slightly enlarged ( Kimmins 1963a, fig. 79). Antennae long, 2– 3 X length of forewing in male; scape large, subspherical. Maxillary palps long, heavily setose, segment 1 shortest, segments 2–5 subequal. Labial palps much shorter, segment 3 longest. Anteromesal setal wart of head large, oval; anterolateral setal warts small, oval; posterolateral setal warts elongate oval. Tibial spurs 0, 2, 2 or 1, 2, 2; foretibial spur, if present, very small. Forewing narrow to broad, apex broadly to acutely rounded; with sparse to dense, short decumbent hairs on membrane, and with conspicuous erect setae along veins; coloration variable, from light brown with cream colored hairs to dark brown with scattered small patches or spots of white hairs. Forks I and V present in both wings; in forewing, thyridal cell 1.5 to nearly 3 times as long as discoidal cell, fork I with short stalk; forewing anastomosis straight or slightly oblique, veins not contiguous; hind wing with stem of Rs degenerate in some species; fork V long.

Male genitalia. Abdominal segment IX annular, setose, anterior and posterior margins generally parallel; tergum IX short to long, shortest at insertion of preanal appendages; sternum IX extended posteriorly, entire, shallowly or deeply excised apically, apicolateral corners generally rugose; posterior process of segment IX extended dorsad to form heavily sclerotized, ovate to triangular, generally rugose projection. Preanal appendages oblong, heavily setose. Inferior appendages spatulate, setose, apex directed mesad; mesolateral surface with setose ridge or processes, basoventrally and mesobasally with seta bearing processes. Tergum X saddleshaped, dorsolaterally with short protuberances; in dorsal view apex entire or trifid. Phallic apparatus short, compact; phallobase tubular, apparently fused with phallicata; basoventrally with sclerotized flange apparently articulating with base of fused inferior appendages; phallicata strongly down turned apically, with heavily sclerotized lateral flanges, dorsolateral corners projecting; parameres absent; phallotremal sclerite not discernable.

Female genitalia. Segment IX short. Tergum X triangular; in dorsal view rounded or triangular; basoventrally generally with papillate processes. Preanal appendage digitate, setose. Lamellae very large, constricted basally, directed ventrad, surfaces setose. Basolateral edges of gonopod plate produced into flanges, surface with fine striations. Spermathecal sclerite complex, in ventral view broadly oval to rectangular, laterally with semimembranous flanges, medially with key-hole shaped sclerite.
