Description

Description. Male / female approximate measurements: length 13 / 12 mm, ring 12 paranota width 1.3 / 1.3 mm. Live colour not known; in alcohol, completely decoloured. Most non-gonopod details as for T. armatum, but antennomere 3 longest, ring 12 paranota 1.3 × as wide as prozonite, leg 6 tarsus 1.5 × as long as femur. Ring 6 sternite with legs 6 closer together than legs 7; legs 6 and 7 tabs long with sparse fine setae (not in discrete brushes); no setae on anterior margin of sternite. Gonopod telopodites straight, tapering distally; base extended posterolaterally as distally concave shelf; posterior surface with thickened longitudinal ridge to ca 1 / 2 telopodite height. Telopodite apex with four processes: (a) pointed, rod-like process arising on anterior surface and directed distally; (b) large, rod-like, pointed process arising on posterior surface, bent at base and directed laterally; (c) laminate process arising apically and curving posteriorly, the tip sometimes notched; (d) small solenomere arising posteromedially and directed posterodistally. Apex produced as small, rounded knob between solenomere and laminate process. Basal shelf concavity with long, fine setae; row of short, stout setae on posteromedial surface to ca 3 / 4 telopodite height, increasing in length and thickness distally. Prostatic groove on medial surface of telopodite, curving gradually to solenomere base. Female with sternites as wide as long; posterior margin of epigynum produced as short trapezoid.
