Description of the male

Body. – TL 1.9 mm, EW 0.9 mm. – Oblong-oval, weakly convex dorsally, weakly glossy brown, covered with brown recumbent setation. – Elytra brown with yellowish-orange patterns covered by yellow setation.

Reviewer:

Head. – Brown, with dense and coarse punctures; covered by brown, recumbent setation. – Labrum brown. – Eyes prominent laterally in dorsal view, coarsely faceted and slightly emarginate near antennal insertions. – Antennae with 11 antennomeres, light brown (Fig. 5). – Palpi light brown, apical maxillary palpomere large, cylindrical.

Pronotum. – Brown, yellowish-orange latero-apically covered by yellow setation with yellowish-orange spot near scutellum, convex dorsally, rugose, withlarge, dense punctures, otherparts coveredwithbrownrecumbentsetation; widestat middle, gradually narrowedanteriad and posteriad. – Anterior margin slightlyarcuate. – Lateralsides roundly arcuate. – Basalmargin sinuate,without short and circular grooves on subbasal parts.

Scutellum. – Light brown, with short recumbent yellow setation.

Elytra. – Dark brown with yellowish-orange patterns, covered by brown recumbent setation, patterns covered by yellow setation, elongate, subparallel-sided, narrowed from apical 1/4 part to apex ( Fig. 2).

Epipleuron. – Brown, covered with brown recumbent setation.

Meta-meso ventrites. – Brown, with brown recumbent setation, finely punctate.

Legs. – Entirely light brown with light brown spines, covered with brown recumbent setation. – Tibiae with long brown spines apically.

Abdominal visible ventrites. – Light brown, finely punctate, covered with brown recumbent setation.

Pygidium . – Brown, covered with brown recumbent setation.

Genitalia. – As in Fig. 8.

Female. – Similar externally to male.

Differential diagnosis. – The new species is similar to Litargus (Litargus) raffrai Grouvelle, 1914 and L. (Litargus) crassus Grouvelle, 1914 , but differs from them by the heart-shaped elytral pattern and structure of the antennae.

Etymology. – Patronymic, dedicated to Cédric Cauquil, specialist of the Phasmidae , who supports us in our ongoing projects in the Sao Tome and PrincipeArchipelago.
