Toliaridectes meridionalis n. gen. n. sp., here described.

Holotype male. Madagascar, province Toliara,région Anôsy, Réserve de Berenty ; 25.0096°S, 46.3079°E, 26.iii.2005, N. Cliquennois leg., MNHN (MNHN-EO-ENSIF 10799). GoogleMaps

Male paratype. [ Madagascar, province Toliara, region Androy, district Beloha], Beloha ; iii.56. AR.

Female (not a type). Madagascar, province Toliara, région Anôsy, Réserve de Sainte-Luce ; 24.8028°S, 47.1636°E, 15.iii.2005, N. Cliquennois leg., coll. SH GoogleMaps .

Remark: since the female has been collected in a relatively distinct area (ca. 90 km apart), in a more humid and coastal environment, I prefer to exclude it from the type series since further specimens may prove it to belong to another species.

Other females possibly belonging to that species but from more northern localities: [ Madagascar, province Toliara, region Atsimo-Andrefana,] Sakaraha, Lambomakandro, III-56 A.R., MNHN; Lohela, Mahala, 11. VI .1964 ; Madagascar Sud, D. Wintrebert Rec., MNHN; LoHena, Mahala, 11. VI .1964 Madagascar Sud, D. Wintrebert Rec., MNHN.

Diagnosis. Color: hind femur with distinct shiny black longitudinal pattern on external (outer) field ( Fig. 22 View FIGURES 10–24 , similar pattern in T. wendenbaumi n. gen. n. sp., pattern weaker in T. antsycurvis n. gen. n. sp.). Male. Xth abdominal tergite emargination as deep as wide ( Fig. 36 View FIGURES 34–54 ; similar in T. wendenbaumi n. gen. n. sp., wider in T. antsycurvis n. gen. n. sp.); paraprocts with a long digitiform projection ( Fig. 35 View FIGURES 34–54 ; wide and short projection in T. wendenbaumi n. gen. n. sp., shorter digitiform projection in T. antsycurvis n. gen. n. sp.). Cercus median projection long ( Fig. 37 View FIGURES 34–54 ; as long as in T. antsycurvis n. gen. n. sp., shorter in T. wendenbaumi n. gen. n. sp.). Subgenital plate wider than long ( Fig. 34 View FIGURES 34–54 ; similar in T. antsycurvis n. gen. n. sp., longer than wide in T. wendenbaumi n. gen. n. sp.). Titillators distal end pointing ( Fig. 55 View FIGURES 55–57 ; similar in T. wendenbaumi n. gen. n. sp., enlarged distally in T. antsycurvis n. gen. n. sp.). Female. Subgenital plate wider than long, with U shaped emargination ( Fig. 58 View FIGURES 58–63 ; wider than long in T. antsycurvis n. gen. n. sp., about as long as wide in T. wendenbaumi n. gen. n. sp.). Ovipositor very long for the genus ( Fig. 59 View FIGURES 58–63 , Table 1 View TABLE 1 ).

Description. Size average for the genus ( Table 1 View TABLE 1 ). Color (male holotype and females only; the male paratype is discolored): head genae without distinct black pattern; hind femur with distinct shiny black longitudinal pattern on external (outer) field ( Fig. 22 View FIGURES 10–24 ). Male. Xth abdominal tergite emargination as deep as wide ( Fig. 36 View FIGURES 34–54 ); paraprocts with a long digitiform projection ( Fig. 35 View FIGURES 34–54 ). Cercus dorsal lobe with angulose tip; median projection long, bilobate ( Fig. 37–40 View FIGURES 34–54 ). Subgenital plate wider than long; with shallow but distinct emargination; styli separated by less than styli length ( Fig. 34 View FIGURES 34–54 ). Titillators distal end pointing; internal part shaped as inverted narrow Y ( Fig. 55 View FIGURES 55–57 ). File with ca. 38 teeth ( Fig. 27 View FIGURES 25–33 ). Female. Subgenital plate wider than long, with U shaped emargination ( Fig. 58 View FIGURES 58–63 ). Ovipositor very long for the genus, ventral margin with a long strait area ( Fig. 59 View FIGURES 58–63 , Table 1 View TABLE 1 ).
