Material examined. Holotype. “Museum Paris Sainte-Marie-de-Madagascar Coll. Noualhier 1898”, “obscurus sp. n ", “Muz. Zool. H:fors Spec. typ. No 12121 Poeciloscytus obscurus Popp ”, male (MZHF).
First description of male terminalia. Right paramere (Fig. 20 I) small, about 0.28 times as long as left paramere. Body rather strongly dilate distally, with very small membranous apical part. Hypophysis shifted sideways.
Left paramere (Fig. 20 J, K). Sensory process from posterior view as in Ch. bimaculatus. Hypophysis from lateral view as in the latter species, but with longer inferior margin and more acute anterio-inferior angle and with less convex posterior part of superior margin.
Theca with apical margin having only one large triangular blade.
Vesica (Fig. 22 D, E) rather small. Secondary gonopore rather small, lies at left wall of vesica, with complete ring of concentrically curved spinulae. Anterior branch of anterior right lobe rather short, directed anteriad and to left, without membranous tubercle and anterior spicule at superior surface. Right branch of anterior right lobe shorter and wider then anterior branch, with widely rounded apex, directed posteriad and downwards. Anterior branch of basi-apical sclerotised band very short, not extends on anterior right lobe. Posterior part of vesica rather dilated, with very short, widely rounded apex. Medial right lobe short and wide, its right branch very short and wide, directed upwards and anteriad, widely rounded. Left branch conical, wide and extremely short. Medial spicule as in Ch. bimaculatus, but directed to left. Posterior spicule longer and thicker than in the latter species, slightly curved, directed anteriad and upwards. Posterior branch of basi-apical sclerotised band reaches base of posterior spicule. Posterior right lobe with two branches and very short base. Posterior branch moderately long, narrow, directed to right and downwards, curved before acute apex. Anterior branch very short and wider then posterior one, lies on anterior side of base of the latter and directed anteriad. Left carina serrated on all length, except for narrow and sharply curved upwards middle. Anterior part of carina reaches secondary gonopore, slightly narrower then posterior part and not forming process. Posterior wall of vesica membranous, without tubercle.
Female unknown.
Distribution. Madagascar.
Taxonomic notes. This species is transferred into the genus Charagochilus based on the following characters: collum about 1.5 times as long as width of the antennal segment (Fig. 41 C); punctures on pronotum deep and rather large; preocular part of head short; claw without denticle; left paramere with flattened laterally, dolabriform hypophysis; apical margin of the theca with only one blade; vesica with the left carina, medial right lobe bearing lamellar medial spicule, with the posterior spicule lying between bases of the medial right and posterior right lobes, without anterior and posterior left lobes; the secondary gonopore with complete ring of concentrically curved spinulae.
