( Figs 8, 10, 12 , 37–42 ) Description. Measurements. Male body length 10.82 mm ; head width 2.53 mm ; crown length×width 0.83× 1.13 mm ; eye width 0.82 mm ; frontoclypeus length 2.15 mm ; clypellus length 1.04 mm ; pronotum length×width 1.13× 3.15 mm ; mesonotum length 1.95 mm . Female unknown. Crown pale with two broad black bands longitudinally, pronotum cover with deep brown granules ( Fig. 8 ). Face black with tiny brown spots, clypellus distal half eXpanded, apeX emarginate ( Fig. 10 ). Elytra piceous with fine pale spots ( Fig. 12 ). Legs brown. Ratio of crown, pronotum and mesonotum+scutellum midline about 1:1.36:2.35. FIGURES 37–42. Tialidia hama sp. nov. Holotype: 37. Pygofer and segment X, ventral vieW; 38. Pygofer and segment X, lateral vieW; 39. Aedeagus, style and connective, ventral vieW; 40. Aedeagus and dorsal connective, lateral vieW; 41. Connective, caudal vieW; 42. Subgenital plate, ventral vieW. Scale bars = 1 mm. Male genitalia. Pygofer large with caudoventral and caudodorsal processes small ( Fig. 38 ). Segment X broad, lateral margins slightly convergent distally ( Fig. 37 ). Aedeagus robust, with evaginations throughout, apeX concavely eXcavated ( Fig. 40 ), distal third of shaft strongly recurved, hook-like in ventral view, lateral margin with numerous strong spines ( Fig. 39 ). Shaft of aedeagus with helical arrangement of numerous macrosetae ( Fig. 39 ). Gonopore cryptic, ventral in basal third ( Fig. 39 ). Dorsal connective stick-like ( Fig. 40 ). Style broad, shorter than half of aedeagus shaft, apophysis irregularly tapered distally ( Fig. 39 ). Connective triangular basally, anterior stem shorter than arms, anterior margin rolled ( Fig. 41 ). Subgenital plate slender, with row of lateral setae eXtended over most of length, apeX rounded with fine spines ( Fig. 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. 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.
