Manzumbadoa bradysioides
sp. n.
(
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.

, 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.

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.
