Introduction
The picture-winged flies — Ulidiidae (= Otitidae) — are rather small family of some 700 species,
distributed predominantly in the New World and, to a lesser degree, in the Palaearctic Region, with few
species widespread into tropical Africa, Asia, and into Oceania. Based upon available collection material,
approximately 134 species of 31 genera of the family Ulidiidae are recognized in Central America, of which
at least 66 species and 2 genera are undescribed. The Mesoamerican fauna is estimated to include about
40 genera and 160 species (Steyskal, 1968, 1971; Kameneva, 2004; Kameneva, Korneyev, 2005).
While examining material in the collection of the Instituto National de Biodiversidad (Santo Domingo,
Costa Rica), some uncommon specimens attracted my attention, certainly belonging to an undescribed
species. This new species belongs to the tribe Lipsanini (= Euxestini) of the subfamily Ulidiinae, and is
related to Eumecosomyia Hendel, Eumetopiella Hendel, Stenomyia Hendel and Zacompsia Coquillett. It
certainly does not fit the diagnosis of any known genus and deserves establishment of a new monotypic genus.
Lipsanini are most abundant in tropical and subtropical parts of the Americas, reaching temperate zones
of the USA and Canada, and Argentina and Chile. Some genera are endemic to Pacific islands, while others,
like Acrosticta Loew, Euxesta Loew, Pseudeuxesta Coquillett, are introduced into Africa, Europe and islands
of Indian Ocean. Except for dull gray or brown Oceanian species, coloration in most species of this tribe is
metallic green or bluish.
The material is deposited in the collections of the Instituto Nacional de Biodiversidad, Santo Domingo,
Heredia, Costa Rica (INBio) and Tel Aviv University, Israel (TAU).
Morphological terminology follows J. F. McAlpine (1981).

gosternum 8 narrow, transversely wrinkled, with dorsal and ventral rows of sensillar
setulae; cercal unit separated, blunt oval, with 3 pairs of longer and one pair of short-
er setae, plus several short trichoid sensillae (fig. 1, 9). Two subspheric, smooth sper-
mathecae on two separate ducts (fig. 1, 7). Vagina with simple ventral receptacle as on
figure 1, 8.
D i s c u s s i o n. In the key to genera of Ulidiinae (excluding Seiopterini) of Central
America (Kameneva, Korneyev, in press) Vladolinia runs together with Zacompsia
Coquillett. Vladolinia differs from the latter by the following characters: eye longer than
high (higher than long in Zacompsia); scutellum cone-shaped, protruding dorsally
(almost flat in Zacompsia); aculeus narrow, with cercal unit blunt oval, non-flattened
(dorso-ventrally flattened, with flattened, apically pointed cercal unit in Zacompsia);
anal lobe wider than cell bcu in (anal lobe narrower than or as wide as cell bcu in
Zacompsia).
The new genus belongs to the tribe Lipsanini (= Euxestini) of the subfamily
Ulidiinae because the female abdominal sternites 4–6 are without antero-medial
apodemes, male have bare phallus without apical glans-like formation, surstyli without
prensisetae (teeth-like setulae) and body in both sexes has green metallic sheen.

setulae at apex. Proboscis capitate, reddish-yellow with brown and black setulae.
Thorax brownish black with greenish sheen, sparsely whitish microtrichose, with

shining. Mesonotum with two subshining brownish microtrichose stripes without green-
ish sheen; postsutural portion of scutum with two copper-reddish vittae on sides, bluish,
rather densely microtrichose between dorsocentral setae. Scutum 1.5 times as long as
wide. Scutellum brownish-black, with stronger greenish sheen on anterior surface and
often brown on posterior surface. All setae and setulae of the thorax brown to black.
Wing elongate; 2.9–3.1 times as long as wide; costal vein between vein Sc and vein
R1 apices unmodified, almost straight. Pterostigma brown, 5–7 times as long as wide.
Wing pattern almost uniformly brownish-gray with yellowish base, including basicostal

mur, proximal one third of mid and hind femora yellow; distal two thirds of mid and

shorter than tergite 4. Terminalia as shown on figures 1, 6–9. Tergosternite 7 brown,
with faint greenish sheen, black setulose, longer than each of tergites.
Mea s u r emen t s. Male. Body 6.0–7.2 mm, wing 4.0–4.6 mm. Female. Body (with
oviscape) 7.2–8.1 mm, wing 5.0–6.5 mm, oviscape dorsally 0.75–1.0 mm, aculeus
