description: <i>Eupyrgota alienata</i> (Walker), comb. n. (fig. 2) <i>Oxycephala alienata</i> Walker, 1861: 22. — <i>Eupyrgota scioida</i> Hendel, 1908: 149, <b>syn. n.</b> Material. <b>Type.</b> Holotype Ơ <i>Oxycephala alienata</i> Walker: “Cer.” (paper circle), “alienata” (Walker’s handwriting), “alienata / Ceram Walker” (Walker’s handwriting), “Holo / type [red bordered circle]”, “Holotype Oxycephala alienata Walker verified J. E. Chainey 2002”, “BMNH # 252215”. Directly pinned, with holes in both wings. (BMNH). Holotype &amp;female; <i>Apyrgota scioida</i> Hendel: “ Buru, Molukken (leg. Frühstorfer), ungar. National-M&amp;imath;&amp;imath;seum”, not located; apparently lost. <b>Non-type</b>. Indonesia: Amboin, “Lichtfang” (at light), 15.07.1960, 1 Ơ (A. M. R. Wegner) (NHMB) (“ Apyrgota scioida ” [Keiser (?) det.]). D e s c r i p t i o n. M a l e. H e a d (fig. 2, <i>3–4</i>) higher than long, length: height: width ratio — 1: 1.45: 1.15, brownish yellow except black spot on subocular sclerite. Vertex with conspicuous transverse ridge. Frons depressed, matt, sparsely and short brown setulose; ocellar triangle and vertical plates poorly or not distinguishable. Orbits shining yellow, without sculpture; parafacial moderately wide, at its widest point shorter than flagellomere 1; eye 2.2 times as high as long and 4.5 times as high as gena; subocular sclerite subshining, three times as high as soft portion of gena; face shining, twice as high as wide in its widest point; antennal grooves separated by low and inconspicuous carina; epistoma low, 0.17 times as high as face, transverse bar-like; clypeus as high as epistoma, large, brown. Antenna yellow, pedicel 1.1 times as long as flagellomere 1; flagellomere 1 2.2 times as long as wide, blunt at apex, matt, but not conspicuously microtrichose; arista two-segmented, bare. Palp yellow, moderately densely and short brown setulose on apical half on lateral and ventral sides; long, wide and flat, 2.5 times as long as wide and slightly wider than flagellomere 1. Proboscis very large and densely brown setose. Short, poorly differentiated brown setae: 1 poc, vti, vte and 1–2 proclinate fr; oc absent. T h o r a x brownish yellow, with prosternum, anepisternum and katatergite partly, and anepimeron, katepisternum, mediotergite, meron and metapleuron black. Scutum brown, along posterior margin narrowly dark brown, brown setulose and setose; setulae with reddish-yellow sheen. Scutellum yellow. Setae short, 1.2–2 times as long as moderately long and dense setulae. 1 ppn, 2 npl, 1 prst, 1 sa, 1 pa, 1 ia, 1 dc, 0 ac; 4–5 short, upturned sctl (on each side of scutellum); proepisternum fine and short yellow setulose; 1 anepst, 1 anepm; no conspicuous posterodorsal kepst. W i n g (fig. 2, <i>5</i>) yellowish-brown on anterior half, grey on posterior half, slightly lighter in cell dm; narrow, 3.5 times as long as wide; wing length — 16.5 mm. Costal and medial vein conspicuously narrowed apically, but reaching each other at apex. Veins C and R 1 golden-brown setulose. L e g s. Fore and hind coxae dark brown basally (fig.2, <i>6</i>), yellow on apical two-thirds to onefourth, mid coxa entirely yellow; fore and mid trochanters yellow, hind trochanter partly brown; without modified setae. Femora yellow, with brown spot or ring at basal one-sixth; subbasal seta as long as femur width; other setae indistinguishable from surrounding setulae; setae in apicoventral rows very slightly thickened, not really spur-like. Tibiae entirely yellow, rather thick, short and densely setulose, conspicuously constricted on basal one-third; mid tibia with very short apicoventral setae (less than 0.3 times as long as tibia width). Tarsi yellow, tarsomeres symmetrical, with pair of dense brushes of setulae on ventral surface and sparse, thin and slightly curled hairs among them. All setae and setulae brown or yellow, with golden sheen. Abdomen yellow, syntergite 1 + 2 with double black crossbands, medially joined in H-like mark, 1.2 times as long as tergites 3 and 4 together or tergite 5. Tergites uniformly covered by moderately dense and rather short golden-brown setae. Synsternite 1 + 2 black on anterior half, yellow on posterior, Y-shaped, twice as long as width at anterior margin and 6.5 times as long as width at posterior margin. Sternites 3 and 4 twice as long as wide at their posterior margins, slightly narrowed anteriorly. Sternite 5 1.6 times as long as wide, at posterior margin slightly incised, 1.5 times as wide as wide at anterior margin. Sternites 3–5 posterolaterally with group of rather long setae in addition to moderately long ones on disk. P o s t a b d o m e n not dissected. Sternite 8 long gold setose. Epandrium (in situ) elongate, as illustrated for <i>E. latipennis</i> (Walker) and <i>E. caffra</i> (Loew) (Korneyev, 2006 a: fig. 6, <i>1</i> and 8, <i>6–8</i>); phallus not extracted for examination. R e m a r k s. <i>Eupyrgota alienata</i> is known to me from two males only. The original description of <i>Apyrgota scioida</i> is rather incomplete, but it is sufficient together with the figure of the holotype female (see Hendel, 1909: fig. 13, 14) to clearly indicate that it is conspecific with <i>E. alienata.</i> They share all the essential characters, and I synonymize these two species names. Though one of the three diagnostic characters of <i>Eupyrgota</i> (s. str.), namely the paired hooks on the oviscape, remains unexamined for this species, the males share well developed nipple-like ventral processes of the prosternum and the shape of the epandrium with the other species of the nominative subgenus and belongs here. I therefore transfer the type species of <i>Apyrgota</i> Hendel, 1909 into <i>Eupyrgota</i> Coquillett, 1898 (s. str.) and consider these genus-group names to be synonyms.
