Description.

Body elongate elliptic, moderately convex. Mandibles, head, pronotum, scutellum, elytra, ventral surfaces including coxae, femora and tibiae dark reddish brown; labrum, most of frons, antennomeres 6–10 and basal half of 11, and distal end of femora brown; basal antennomeres, apex of antennomere 11, palpi and tarsi pale brown. Length: 4.1 mm; width: 2.1 mm (male paratype: 4.5 mm long, 2.3 mm wide; female paratypes: 4.1–4.8 mm long, 2.2–2.6 mm wide).

Note.

Objective coalescent-based species delimitation separated as different species the sequences obtained from individuals of C. spadicea sp. nov. from Pic du Pin and from the Haute Rivière Bleue. The specimens from both localities are morphologically very similar, including the atypical homogeneous brown colour of dorsal surfaces and also the overall shape and attributes of penis (Fig. 7 i View Figure 7 ) and spermatheca (Fig. 1 w View Figure 1 ). However, the difference in size and also their occurrence in apparently different biomes, drier in the case of the former and humid forests in the case of the latter, together with the results of objective species delimitation, compelled us to establish a taxonomic differentiation between these populations as different subspecies.

Diagnosis.

The individuals of this subspecies are fundamentally identical to the nominotypical species, but smaller in size. The studied series are small, but it appears as if in this subspecies the sides of the fifth abdominal ventrite had more defined serrate margins compared to the nominotypical subspecies.

Derivatio nominis.

The subspecies name is a Later Latin adjective (f.), bruna, meaning brown, to insist on the uncommon brown colouration of the specimens.

Distribution.

This species is at present only known from two nearby low elevation localities in the southeastern part of the Réserve naturelle du Pic du Pin and in Pic du Grand Kaori, in the south of Grande Terre (Fig. 8 e View Figure 8 ).
