Fig. 1, 4, 7, 10, 13, 16, 19, 22, 25–27, 34–40, 55, 58–59, 72, Tab. 1.
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).
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.
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, 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; similar in T. wendenbaumi n. gen. n. sp., wider in T. antsycurvis n. gen. n. sp.); paraprocts with a long digitiform projection (Fig. 35; 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; 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; similar in T. antsycurvis n. gen. n. sp., longer than wide in T. wendenbaumi n. gen. n. sp.). Titillators distal end pointing (Fig. 55; 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; 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, Table 1).
Description. Size average for the genus (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). Male. Xth abdominal tergite emargination as deep as wide (Fig. 36); paraprocts with a long digitiform projection (Fig. 35). Cercus dorsal lobe with angulose tip; median projection long, bilobate (Fig. 37–40). Subgenital plate wider than long; with shallow but distinct emargination; styli separated by less than styli length (Fig. 34). Titillators distal end pointing; internal part shaped as inverted narrow Y (Fig. 55). File with ca. 38 teeth (Fig. 27). Female. Subgenital plate wider than long, with U shaped emargination (Fig. 58). Ovipositor very long for the genus, ventral margin with a long strait area (Fig. 59, Table 1).
Deriviatio nominis. After the distribution of the species, in the South of Madagascar.
