Diagnosis.
Aedeagus in ventral view strongly narrowing from middle to apex; with short asetose lateral subapical lobes; with long and slender lateral apical projections with narrow distal parts, each bearing submedian seta.
Description.
BL
0.78 mm
. Body of male (
Fig. 3
) moderately convex, dark brown, covered with vestiture slightly lighter than cuticle.
Head broad in relation to pronotum (PW/HW 1.33), broadest across the large and strongly convex eyes, HL
0.13 mm
, HW
0.19 mm
; vertex weakly convex; frons flattened and with a pair of shallow but distinct circular pits between eyes; supraantennal tubercles indistinct. Punctures on vertex and frons inconspicuous, fine and sparse; setae sparse and short, suberect. Antennae slender, AnL
0.30 mm
, antennomeres I–II elongate, III–V as long as broad, VI–VIII slightly transverse, IX–X strongly transverse; XI about as long as IX–X together.
Pronotum semi-oval, broadest near base, barely noticeably broader than long; PL
0.23 mm
, PW
0.25 mm
; anterior margin weakly and evenly rounded; lateral margins strongly rounded in anterior half and weakly rounded in posterior third; posterior pronotal corners distinctly obtuse and blunt; posterior margin distinctly arcuate with short and shallow emargination in front of mesoscutellum; base with shallow but distinct transverse impression connected at each side with a distinct and nearly circular sublateral pit, lateral pits distinct and elongate, located anterolaterally in relation to sublateral pits. Punctures on pronotal disc fine and sparse; setae sparse but relatively long, suberect.
Elytra oval, broadest near middle; EL
0.43 mm
, EW
0.34 mm
, EI 1.26; humeral calli prominent, elongate. Punctures on elytral disc much more distinct than those on pronotum, small and shallow but obvious, separated by spaces subequal to puncture diameters; setae similar to those on pronotum, sparse, long and suberect.
Hind
wings well developed.
Legs moderately long and slender, unmodified.
Aedeagus (
Figs. 9–10
) elongate; AeL
0.16 mm
; in ventral view median lobe slightly asymmetrical in basal part and strongly narrowing distally; ventral membranous area (
Fig. 9
;
vma
) small, circular and located at base; lateral subapical lobes (
Fig. 9
;
lsl
) present, short, without apical setae; lateral apical projections (
Fig. 9
;
lap
) present, symmetrical, flexible, slender and recurved, each with long seta located on external margin of submedian part; assemblage of median apical projections (
Fig. 9
;
map
) nearly symmetrical, composed of lateral pair of elongate sclerites and median copulatory piece; parameres slender, each with very long apical and very short subapical seta.
Female. Unknown.
Distribution.
Australia
, Far North Queensland (Cape York) (
Fig. 4

Etymology.
The name
angustifurculata
refers to the slender lateral apical lobes of the aedeagus, after Latin

(narrow) and
furcula
(forks).
