Figs. 3 View FIGURES 3 B–C, 6 B–C, 8 P, 9 A, 10 I, 13 A–D, 44 A–G.

Male and female. General habitus uniformly deep ochraceous. Eyes and ocelli black. Face creamy white with yellowish tinge, lateral margin pale brown. Pronotum, mesonotum and forewing with numerous pale, yellow spots. Hind coxae and bases of setae on hind tibiae fuscous. Hind femur with apices and claws, dark brown ( Figs. 3 View FIGURES 3 B–C, 6 B–C, 8 P, 9 A). Female seventh sternite posterior margin with concave, medial lobe ( Fig. 10 I View FIGURES 10 ).

Male genitalia. Pygofer in lateral view more or less triangular with small rounded caudodorsal lobe and small blunt, ventral digitate process ( Fig. 44 G View FIGURES 44 ). Subgenital plate long, slightly curved and narrowed towards rounded apex ( Fig. 44 D View FIGURES 44 ). Style symmetrical, apophysis broad at base and slightly tapered with blunt apex ( Fig. 44 E View FIGURES 44 ). Connective longer than wide at base with prominent median ledge extending entire length ( Fig. 44 F View FIGURES 44 ). Aedeagus slightly curved near apex in lateral view with four subapical processes, three on one side glabrous, large single subapical process on opposite side extending far beyond three processes, with numerous lateral secondary spines in distal 1/3 ( Figs. 44 View FIGURES 44 A–C).

Female genitalia. Valvulae I slightly curved, sculptured in apical ¼ ( Figs. 13 View FIGURES 13 A–B). Valvulae II with four prominent, basal teeth followed by fewer prominent teeth on dorsal margin, toothed area confined to apical ¼ ( Figs. 13 View FIGURES 13 C–D).

Measurements. Male 6.5−6.7 mm long, 1.7 mm wide across eyes and 1.9 mm wide across posterolateral angles of pronotum. Female 8.9−9.2 mm long, 2.1 mm wide across eyes and 2.6 mm wide across posterolateral angles of pronotum.

Etymology. The species name is descriptive for the long, dialated setaceous process of the aedeagal shaft.

Remarks. T. dialata   sp. nov. is a pale species. The aedeagus has four subapical spines—three narrow spines and one large, inflated process with secondary processes. This species is nearest to T. piperica   sp. nov. which also has similar processes. From T. piperica   , T. dialata   can be separated by the short row of secondary processes laterally on the distal 1/3 of the inflated process, whereas T. piperica   has secondary processes laterally on the entire process. The specimen from Rajasthan has the secondary setae on the distal ¾ of the proximal process of the aedeagal shaft. This species was attended by ants, Camponotus   sp. ( Hymenoptera   ) ( Figs. 54 View FIGURES 54 A–B).
