Head: Eyes large, nearly connate; eye bridge about 7 facets long; facets circular, closely approximated except separated at vertex by diameter of ½ to 1 facet. Occiput without dorsal protuberance.Antenna with 12 flagellomeres, all binodal (Fig. 2) but 12 th with a narrow apical prolongation, basal node shorter than distal, with 1 circumfilum, distal node with 2, circumfila all with uniformly short loops; internode and necks long, each about as long as basal node (Fig. 2). Frons with 6–8 strong setae on each side. Mouthparts (Fig. 3): Labella broad in frontal view, with several short, thin setae; palpus 4-segmented with scattered, uniformly thin setae of similar size as on labella, without scales, palpiger prominent.</p><p>Thorax: Scutum with 4 discrete longitudinal ranks of setae, median ranks with mostly 2 rows of continuous setae, lateral ranks with multiple rows but interrupted near midlength. Scutellum covered with setae on dorsum. Thoracic pleura bare except for 19–23 setae (n=2) on anepimeron. Wing (Fig. 1): length, 5.0– 5.3 mm (n=2); C broken at juncture with R 5; R 5 strongly curved apically to join C posterior to wing apex; Rs reduced to stub, closer to arculus than to apex of R 1; wing fold faint; M 4 and CuA forming a fork. Legs: equally slender throughout, elongate, hindleg nearly twice wing length; acromere (Fig. 4) with robust, gradually and gently curved claws lacking basal tooth, empodia as long as claws, pulvilli about ¼ as long as claws.</p><p>Male abdomen:Tergites 1–6 entire, rectangular, each with mostly double, closelyset row of setae along posterior margin, a group of many lateral setae, a pair of widely spaced anterior trichoid sensilla, and elsewhere covered with long setiform scales; tergite 7 with posterior third membranous and consequently without posterior rows of setae, with group of lateral setae on each side, anterior pair of trichoid sensilla and sEtIfOrm sCALEs COVErIng AntErOmEsAL ⅔; tErgItE 8 fOrEshOrtEnEd, bArE ExCEpt fOr A few anterolateral setae on each side and pair of trichoid sensilla anteriorly. Sternites 2–8 with several rows of strong posterior setae, and pair of closely set anterior trichoid sensilla, these not visible on sternite 8 of the two available slide-mounted specimens, elsewhere covered with setae and setiform scales. Terminalia (Figs 5–11): cerci partly hidden by ninth tergum (two rounded bulges of Fig. 9), rhomboid, longest laterally, with several short setae near pointed apex and fewer along caudal edge; hypoproct (Fig. 5) elliptical, much longer than cerci, dorsoventrally flattened, thickly covered with long, retrorse microtrichia on both surfaces, with several, short, apicolateral, ventral setae; aedeagus elongate, dorsoventrally flattened, nearly parallel-sided throughout, divided apically into median conical lobe and 2 laterally flared and pointed lobes, distal fourth of aedeagus with about 20 bare papillae on each side; gonopods greatly enlarged, broader than and more than a quarter as long as remainder of abdomen, the gonocoxites (Figs 6–8) cylindrical, inclined towards one another apically, concave mesally, longest apicoventrally, distal fourth more densely covered with stout setae than elsewhere; gonostylus (Figs 8, 10) robust, brOAd, COmprEssEd dOrsOVEntrALLY, sOmEwhAt pInChEd nEAr ⅓ Of Its LEngth, bAsAL third covered with strong setae and microtrichia, distal two thirds with some carinae, glabrous, with short setae laterally and basad of apical tooth, tooth consisting of a multitude of minute, parallel, cylindrical fibers (Fig. 11).</p><p>Female, pupa and larva unknown.</p><p><b>Material examined:</b> 4♂ (USNM), <b>Taiwan:</b> “ Noko, 8,000 ft, VI-26-1927, S.

Sauter (Kieffer 1913 <i>a</i>). These are presumed lost as is most of Kieffer’s type material.

Hans Sauter (1871–1943), collector of the original type series, was a German entomologist and ichthyologist, who moved to Formosa (now Taiwan) in 1905 and remained there until his death. Lynsley Gressitt (1914–1982), collector of three of the four extant specimens on three separate occasions, was born in Japan and died in an airplane crash in China. He was an outstanding American entomologist and collector of an enormous number of Oriental and Pacific insects (W.C. Gagné 1982). The collector of the fourth extant specimen was Syûti T. Issiki, a Japanese microlepidopterist who served between 1920–1948 as Professor of Agriculture at the Imperial University at Taipei (Davis 1973).</p> |
