( Figs. 16, 17 , 176–189 , 233 , 239, 240 ) 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 ) . Diagnosis. The combination of a large uncus, unique-shaped dorsal lobes (see Figs. 16, 17 ), 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. 176 ). 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, 17 , 177–189 ). Capsule about 520 µm long, 285 µm wide. Uncus ( Figs. 181 , 184, 186 ) consisting of two long, slender lateral lobes, and two very short, rounded median lobes. Valva divided ( Figs. 16, 17 , 178 , 182–187 ): ventral lobe ( Fig. 180 ) 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, 17 , 185–188 ), and short, bifurcate lobe ( Figs. 16 , 183, 184 ); transtilla absent; basal process of valva rather long ( Figs. 181 , 187 ). Anellus rather indistinct, chitinized laterally, with a few setae on each side. Phallus ( Fig. 177 ) about 425 µm long, distally widely furcated, with two lobe-like processes. Bionomics . Host plant unknown. Adults fly in April. Distribution ( Fig. 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, 240 ). Etymology. The species name is derived from Latin furcatus (forked) in reference to the furcate dorsal lobe of valva in the male genitalia.
