Crown pale with two broad black bands longitudinally, pronotum cover with deep brown granules ( Fig. 8 View FIGURES 1–12. 1,3,5 ). Face black with tiny brown spots, clypellus distal half eXpanded, apeX emarginate ( Fig. 10 View FIGURES 1–12. 1,3,5 ). Elytra piceous with fine pale spots ( Fig. 12 View FIGURES 1–12. 1,3,5 ). Legs brown. Ratio of crown, pronotum and mesonotum+scutellum midline about 1:1.36:2.35.
Male genitalia. Pygofer large with caudoventral and caudodorsal processes small ( Fig. 38 View FIGURES 37–42 ). Segment X broad, lateral margins slightly convergent distally ( Fig. 37 View FIGURES 37–42 ). Aedeagus robust, with evaginations throughout, apeX concavely eXcavated ( Fig. 40 View FIGURES 37–42 ), distal third of shaft strongly recurved, hook-like in ventral view, lateral margin with numerous strong spines ( Fig. 39 View FIGURES 37–42 ). Shaft of aedeagus with helical arrangement of numerous macrosetae ( Fig. 39 View FIGURES 37–42 ). Gonopore cryptic, ventral in basal third ( Fig. 39 View FIGURES 37–42 ). Dorsal connective stick-like ( Fig. 40 View FIGURES 37–42 ). Style broad, shorter than half of aedeagus shaft, apophysis irregularly tapered distally ( Fig. 39 View FIGURES 37–42 ). Connective triangular basally, anterior stem shorter than arms, anterior margin rolled ( Fig. 41 View FIGURES 37–42 ). Subgenital plate slender, with row of lateral setae eXtended over most of length, apeX rounded with fine spines ( Fig. 42 View FIGURES 37–42 ).
Material examined. Holotype: male, Republic of the Congo: Department Pool, Abio Lesio-Loun Wildlife Reserve , 330m, 3°06.020′S 15°34.440′E, 340m, 05–12 Aug. 2008, coll. M. Braet and M. Sharkey. GoogleMaps
Etymology. The new species name is a Latin word, meaning hook, referring to the hooklike apeX of the aedeagus.
Remarks. This species is similar to T. brevita Nielson in having hooked apeX of aedeagus and convoluted arrangement of macrosetae but the new species with a longer aedeagus over twice length of style, and apical hook very strong and curved basad reaching to midlength of shaft, whereas the latter species with a shorter aedeagus and apeX of shaft slightly curved.
