( Figs 1-8 ) Description (for characters not mentioned here, see genus description above) Male. Body length: 2.9-3.1 mm . Head: Antenna with fourth flagellomere 2.2 times as long as wide ( Fig. 1 ). Maxillary palpus as in Fig. 5 . Legs: Fore tibia with anteroapical depression bearing distal comb of some 20 setae ( Fig. 2 ). Wing: See Fig. 3 . Terminalia: Gonocoxites ( Fig. 6 ) with setae of various lengths; with megaseta each ventro- and dorso-distally. Gonostyli ( Figs 6, 7 ) elongate, in distal half tapering to tip, inside and distally with very short setae and long setae elsewhere, with 1 short, thick spine outside subterminally and 3 spines in line apically. Ejaculatory apodeme ( Fig. 8 ) as long as tegmen. Tegmen ( Fig. 8 ) with long, sclerotized ventral apodemes, membranous elsewhere and wrinkled laterally. Tergite 9 ( Fig. 4 ) with setae of various lengths, in distal third very weak and lacking setae and trichia. Tergite 10 ( Fig. 4 ) extending distolaterally beyond tergite 9. Cerci ( Figs 4 , 8 ) large, setose, rounded terminally. Hypoproct ( Fig. 8 ) weak, two-lobed, with 2 setae each. Female. Vor characters not mentioned here, see the above description of the male. Figs 1-4: Manzumbadoa bradysioides sp. n. , male. - 1: fourth antennal flagellomere, lateral view (0.1 mm); - 2: fore tibial anteroapical depression (0.1 mm); - 3: wing (0.5 mm); - 4: terminalia, tergites 9 and 10, dorsal view (0.05 mm). 1 and 2: holotype; 3 and 4: paratypes. Abbreviations in Fig. 3: tb = basal transversal vein; frm = fused radio-media. In parentheses: length of scale bar. Figs 5-8: Manzumbadoa bradysioides sp. n. , holotype male. - 5: maxillary palpus, lateral view (0.1 mm); - 6: terminalia, left side: ventral view, right side: dorsal view, right gonostylus and tergite 9 omitted (0.1 mm); - 7: apex of gonostylus, lateral view (0.05 mm); - 8: ejaculatory apodeme, tegmen and associated structures, ventral view (0.05 mm). Numbers referring to structural elements as follows: 1 = cercus; 2 = hypoproct; 3 = aedeagal teeth; 4 = tegmen; 5 = ejaculatory apodeme; 6 = gonocoxal apodeme; 7 = ventral parameral apodeme; 8 = transverse bridge; 9 = dorsal parameral apodeme. In parentheses: length of scale bar. Body length: 3.0 mm. Abdomen: Segments 1-6 much broader than following segments. Terminalia: Without striking features that deviate from those in other sciarids. Etymology. The species epithet ‘bradysioides’ indicates the similarity between the new species and typical species of the genus Bradysia , a fact that is most strikingly expressed in the outline of male terminalia.
