Description.
Length. Male:

Coloration. General color light brown with darker brown and orange-red marks (
Fig. 29

Morphology. Head narrower than pronotum, subconical, anterior margin rounded to face, angled (
Fig. 29

Fig. 29
A–D). Apex of anteclypeus widened, extending slightly beyond normal curve of genae (

Fig. 29
A–D). Forewing macropterous, usually exposing apex of abdomen in female (
Fig. 29
A–D).
Male genitalia. Pygofer side without macrosetae, long, dorsal margin deeply concave, posterior margin rounded (
Fig. 30A
). Subgenital plate subquadrate, macrosetae arranged in irregular band and well separated from lateral margin (
Fig. 30C, D
). Style preapical angle indistinct, apophysis robust, digitate, laterallylaterally curvedcurved (
Fig. 30E
). Con-Con-Connective H-shaped, stem broadened distally and nearly as long as arms (
Fig. 30F
). Aedeagal shaft broadly curved dorsad in lateral view divergent from aedeagal base, slightly sinuate, apex attenuate, dorsal view slender with apex abruptly tapered to acute point, with subapical membranous area (
Fig. 30G, H
).

Etymology.
The species epithet is based on the
type
locality.
Distribution.
Madagascar
.
Remarks.
This species can be distinguished from other species of
Stirellus
by the following combination of characters: general color brown without extensive markings (
Fig. 29
A–E); subgenital plate distinctly convex laterally, macrosetae not uniseriate (
Fig. 30
C–D); aedeagal shaft with subapical membranous area (
Fig. 30G, H
). Only one other species of Stenometopiini has been recorded from
Madagascar
so far:
Stirellus minimus
(Evans)
. It differs from
S. madagascarensis
sp. nov.
in its less elongated body, less reflexed costal crossveins, rounded subgenital plate, and strongly acute angle between the aedeagal atrium and shaft.
Malagasiella
was treated as a junior synonym of
Doratulina
by
Zahniser & Nielson (2012)
. The latter genus was considered a junior synonym of
Stirellus
by
Duan
et al
. (2016)
.
