Commatoceropsis perrieri Fairmaire, 1898: 344 (Type locality: Madagascar, Suberbieville [Maevatanana]. Type serie: no information in the original description, five syntypes should be located in MNHN ( Jeannel 1954: 302).

Type material examined. LECTOTYPE: MADAGASCAR: ♂, here designated, seven labels: “Madag / illegible text“ [dirty white, handwritten], “ Commatoceropsis / Perrieri / illegible text Madag“ [dirty white, handwritten], “TYPE“ [red, printed], “ Fusifer / Perrieri F.“ [white, handwritten], “ Sufifer Newt. / = Fusifer Raffr. / perrieri Fairm. / Cl. Besuchet [white, handwritten and printed], “PHOTO (P. Krásenský) / P. Hlaváč, Prague“ [yellow, printed], “ SYNTYPE / SUFIFER / perrieri (Fairmaire) / P. Hlaváč des., 2022“ [red, printed] ( MNHN). Note . Lectotype with small red square label which means that a microscopic preparation of the aedeagus should be held in MNHN, it was not available for this study. PARALECTOTYPE: MADAGASCAR: 1 ♀, six labels: “Madagascar“ [white, handwritten], “ Commatoceropsis / Perrieri / illegible text Madag“ [dirty white, handwritten], “TYPE“ [red, printed], “ F. Perrieri / A. Raffray det.“ [white, handwritten and printed], “MUSÉUM PARIS / 1917 / COLL. A. RAFFRAY“ [bleu, printed], “ SYNTYPE / SUFIFER / perrieri (Fairmaire) / P. Hlaváč des., 2022“ [red, printed] ( MNHN) .

Diagnosis. Antenna short, about 0.35 mm long, terminal antennomere less than twice as long as wide; pronotum with ill-defined median sulcus, with well-defined median fovea; first visible paratergite strongly protruding laterally, distal lobe of aedeagus very short, more times shorter than basal bulb.

Redescription. Body length 2.1–2.2 mm. Head capsule sub-rectangular, about 1.2 times as long as wide, slightly longer than pronotum, with two sub-parallel carinae; lateral sides moderately dentate from under eyes to posterior margin of head capsule; anterior margin of rostrum triangular.Antenna 0.35 mm long, antennomere 3 confluent with 4, terminal antennomere about 0.2 mm long, from half of length slightly narrowed to truncate apex.

Pronotum about 1.15 times as wide as long, sides slightly convergent posteriad, widest in about midlength, with about 5 small teeth, lateral, short, slightly dentate carinae only in posterior half; lacking median carina, with ill-defined median sulcus, median fovea well-defined.

Elytra about 1.5 times as wide as long, shorter than abdomen, glabrous, lacking sutural striae, with eight carinae bearing setae, four sutural carinae reaching about half of elytral length, fifth reaching three fourth of elytral length and three lateral carinae entire, lateral elytral margin non-dentate, lacking longitudinal impression.

Abdomen long, about 1.6 times as long as elytra, anterior part of composite tergite with transverse impression, lateral foveae small with ill-defined trichome; first visible paratergite clearly longer than second, with well-defined lateral protrusion bearing well-defined trichome, second visible paratergite parallel-sided, about 1.3 times as long as third visible paratergite.

Legs short and stout; mesofemur with sharp, long, straight basal spine; mesotibia with small preapical spine.

Aedeagus known only from lateral view ( Jeannel 1954: 303, Fig. 163), elongate, apical lobe strongly curved downwards, short; basal bulb about 3.3 times as long as apical lobe.

Sexual dimorphism. Females with mesofemora and mesotibiae simple, lacking spines.

Host ant. Crematogaster hova -complex Blaimer, 2010 [as Crematogaster (Decacrema) schencki Forel, 1891 ].

Distribution. Madagascar.
