New Species And Records Of Hypselothyrea De Meijere (Diptera, Drosophilidae) Author Papp, L. text Acta Zoologica Academiae Scientiarum Hungaricae 2003 2004-06-30 49 4 271 294 journal article 10.5281/zenodo.12586958 2064-2474 12586958 Hypselothyrea (Deplanothyrea) amputata sp. n. ( Figs 24–27 ) Holotype male ( MHNG ): Indonesie , Sumatra (Lac Maninjau): Garonggong , sur le versant du lac, 22. VII. 1984 , leg. J. ROBERT (W), No. 18 [extraction par appareil Winkler-Moczarski]. Measurements in mm: body length 1.75, wing length 1.18, wing breadth (at broadest, i.e. subapically) 0.15. Body much fainted in alcohol, now light brown (probably dark brown when alive). Frontal shield trapezoid, smooth and shiny. Carina only on 1/2 of facial plate. Anterior fronto-orbital pair proclinate and slightly lateroclinate, distinctly shorter than posterior one; ocellar and vertical setae strong. First flagellomere joins pedicel ventrally, first flagellomere with 0.02 mm long bars: 0.4 mm ( Fig. 24 ), 0.05 mm ( Figs 25–26, 29 ), 0.1 mm ( Figs 27–28, 30–31 ) Figs 24–31. 24. Hypselothyrea (Deplanothyrea) amputata sp. n. , holotype male, wing. 25–31. H. (D.) terminalia: 25–27 = H. (D.) amputata sp. n. , holotype, 25 = apex of epandrium and surstylus, broadest extension, 26 = surstylus, broadest extension, medial view, 27 = hypandrium and genitalia, ventral view. 28 = H. (D.) formosana sp. n. , paratype, oviscapt, lateral view. 29–30 = H. (D.) longimana sp. n. , paratype: 29 = surstyli, in view of the broadest extension of the right surstylus, 30 = hypandrium and genitalia, ventral view. 31 = H. (D.) subaptera sp. n. , paratype female, oviscapt. Scale cilia. Palpus with strong apical seta. Arista with 6 dorsal and 2 ventral long branches (rays) behind apical fork. Mesonotum not granulated. Scutellum short, 0.12 mm long, 0.175 mm broad, not upright, but apical scutellars rather perpendicularly upright, 0.21 mm long; basal scutellars present only as 0.035 mm long setulae. Dorsocentrals in 2 pairs. Other thoracic setae: 1 anterior notopleural (posterior one present only as a small hair), 2 supra-alar (anterior one lateroclinate, posterior one upright and slightly inclinate), 1 postalar (only 1/2 as long as posterior dc and much thinner); 1 normal katepisternal pair of setae. Two rows of minute acrostichals. Legs light brown, tarsi even paler. Fore femur without anteroventral spinules, 1 strong posteroventral seta only Wing reduced, not only shortened, but also cubital and anal regions almost completely lost ( Fig. 24 ). C-index 0.41.

Female unknown. Distribution. Indonesia ( Sumatra ). Hypselothyrea amputata sp. n. is a strongly reduced-winged species. It is probably related to H. vanarasiensis GUPTA (2 pairs of dorsocentrals, wing hyaline, etc.). However, not only its wing reduction but also details of male genitalia make it easily identifiable (another note under H. (D.) longimana sp. n. ).
