sp. nov.

Astrotischeria furcata Stonis & Diškus  , sp. nov.

( Figs. 16, 17View FIGURES 16–19, 176–189View FIGURES 176–181View FIGURES 182–189, 233View FIGURE 233, 239, 240View FIGURES 239–244)

Type material. Holotype: ♂, BELIZE: Cayo District, Chiquibul Forest Reserve , Las Cuevas, 16°43'59"S, 88°59'01"W, elevation 590 m, 3–16.iv.1998, R. Puplesis & S. Hill, genitalia slide no. AD 925♂ ( BMNH)GoogleMaps  .

Diagnosis. The combination of a large uncus, unique-shaped dorsal lobes (see Figs. 16, 17View FIGURES 16–19), and the wide apical fork of phallus in the male genitalia distinguishes A.furcata  sp. nov. from all other Astrotischeria  , including other members of the A. trilobata  group.

Male ( Fig. 176View FIGURES 176–181). Forewing length about 3.5 mm; wingspan about 7.5 mm. Head: face and palpi yellowish cream; frontal tuft comprised of lamellar scales, glossy, yellowish cream centrally, ochre to ochre-brown laterally; antenna longer than half the length of forewing; flagellum yellowish grey to grey, basally yellowish cream; sensillae long, greyish white. Thorax glossy, orange-yellow, with a few scattered blackish brown scales; tegula orange-yellow distally, densely covered with blackish brown scales basally. Forewing glossy, mostly yellowish cream with patchy shade of ochre-orange; black-brown scales scattered laterally and form an oblique, subapical spot along costal margin, and a small, indistinct spot on tornus; fringe grey on costal margin, dark grey to pale brown grey on tornus, but yellowish cream on termen; fringe-line absent or indistinct; forewing underside coarsely covered with dark brown scales with weak greenish and purple iridescence, no androconia. Hindwing pale grey to brown (depends on angle of view), without androconia; fringe pale brown to brown. Legs glossy, golden cream, with brown to dark brown scales and some purple iridescence on upper side.

Female. Unknown.

Male genitalia ( Figs. 16, 17View FIGURES 16–19, 177–189View FIGURES 176–181View FIGURES 182–189). Capsule about 520 µm long, 285 µm wide. Uncus ( Figs. 181View FIGURES 176–181, 184, 186View FIGURES 182–189) consisting of two long, slender lateral lobes, and two very short, rounded median lobes. Valva divided ( Figs. 16, 17View FIGURES 16–19, 178View FIGURES 176–181, 182–187View FIGURES 182–189): ventral lobe ( Fig. 180View FIGURES 176–181) wide at basal half, slender at apical half, about 260 µm long (excluding basal process); dorsal lobes consisting of two elements: wide, distally pointed transverse lobe ( Figs. 16, 17View FIGURES 16–19, 185–188View FIGURES 182–189), and short, bifurcate lobe ( Figs. 16View FIGURES 16–19, 183, 184View FIGURES 182–189); transtilla absent; basal process of valva rather long ( Figs. 181View FIGURES 176–181, 187View FIGURES 182–189). Anellus rather indistinct, chitinized laterally, with a few setae on each side. Phallus ( Fig. 177View FIGURES 176–181) about 425 µm long, distally widely furcated, with two lobe-like processes.

Bionomics. Host plant unknown. Adults fly in April.

Distribution ( Fig. 233View FIGURE 233). Known from a single locality in Belize (Las Cuevas Biological Station), the moist tropical forest habitat, at an elevation of about 600 m ( Figs. 239, 240View FIGURES 239–244).

Etymology. The species name is derived from Latin furcatus (forked) in reference to the furcate dorsal lobe of valva in the male genitalia.
