Type material. HOLOTYPE: ♀, INDONESIA: ‘ Coll. I.R. SC.N.B. / Mentawai Isls, S Siberut Isl. , / Salappa, vi. 2005, 50- 100m / leg. St. Jakl / I.G. 31.127’ // (label with red margin) Holotypus (hw): ‘ T. redeii sp. nov. / Varga et Kondorosy, 2013’ ( IRSN). PARATYPE: ♀, ‘INDONESIA, 5.2004 / Siberut isl. / Bojakan, 100 m / S. Jakl lgt.’ // (label with red margin) Paratypus (hw): ‘ T. redeii sp. nov. / Varga et Kondorosy, 2013’ ( MMBC).

Description. Labium reaching mid coxae. Fore femur with two spines and moderately long hairs. Hairs of hind tibia very ¿ne and shorter than tibial spines, spines of hind tibia shorter than diameter of tibia.

Colouration. Body blackish brown. Basal half of endocorium paler brown, narrow transverse fascia along hind margin of pronotum, apex of scutellum and corial spots stramineous. Corium with tiny transverse arched pale stripe posteriad of clavus close to apical margin and with large subapical pale spot reaching apical margin. Subapical spot nearly trapezoidal, on costal margin subapical spot at least 2 times longer than dark apical part. Membrane dark ( Fig. 6 ), with tiny spot at apex of corium, pale colourations of veins not connected to each other nor to the large pale apical spot (having straight basal margin). Antennal segment I brown, IIíIII light brown with dark brown apices, IV blackish brown with basal third stramineous. Legs: femora blackish brown, mid and hind femora pale in basal half, tibiae stramineous, only extreme apex brown, tarsi brown, segment I stramineous.

Measurements (in mm). Body length: 7.97í8.68. Head length: 1.44í1.66, width: 1.31í1.37, interocular space: 0.60í0.64. Pronotum length: 1.44í1.62, width: 1.86í2.02. Scutellum length: 1.22í1.24, width: 0.93í1.02, length of claval commissure: 2.25í2.45. Lengths of antennal segments: I 1.22, II 2.51, III 1.88, IV 2.85. Length of labium: 2.98í3.12, labial segments: I 1.02, II 0.97í1.11, III 0.66, IV 0.33.

Differential diagnosis. Labium longer than that of previous species, reaching mid coxae. Body slightly longer and darker. Subapical spot of corium larger. Membrane with extensively pale veins. Colouration of antennae and legs also different. Antennal segment III relatively short, about 1.6 times longer than I; 0.67 times shorter than IV ( T. prolixicornis: III : I 1.9í2.1; ratio III: IV 0.75í0.82).

Etymology. The species is named after Dr. Dávid Rédei, the excellent Hungarian heteropterologist, who is despite his young age a very signi¿cant and productive researcher of this order, and has been of great help in our work in linguistic and taxonomic matters, too.

Distribution. Indonesia: Mentawai Islands (Siberut Island).
