 Type material. HOLOTYPE: ♀, INDONESIA: ‘ Sulawesi Utara / G. Mogogonipa / summit, 1008m. (back side hw) 21. V. 1985 // at light // R. Ent. Soc. Lond. / Project Wallace / B.M. 1985-10 (back side hw) J.H. Martin / coll. // (red marginated label) Holotypus (hw): ‘ T. longirostris sp. nov. / Varga et Kondorosy, 2013’ (BMNH).   
 Description. Head covered with conspicuous silvery hairs. Fore femur with two or three spines and some long hairs. Scutellum with hardly visible short hairs only. Hind tibiae with short inconspicuous hairs, spines longer than hairs but shorter than diameter of tibiae. Labium much longer than half of body, reaching abdominal segment V, apex of segment I far surpassing anterior margin of prosternum.   
 Colouration. Body stramineous (Figs 7–8). Head, anterior half of pronotum, scutellum and thoracic sternum reddish brown. Scutellum apically and on posterior half of lateral margin white. Clavus and corium stramineous with brown punctures, small claval spot at apex of scutellum, indistinctly limited transverse band at apex of clavus (including tiny transverse arched pale stripe) and extreme apex of corium brown (pale part on costal margin at least 4 times longer than dark apex). Membrane brown, with stramineous streak reaching from base of costal margin to third vein at one third of inner margin, apex extensively pale with straight basal margin. Antennal segment I brown, segments IIíIII stramineous, apically dark brown, basal half of segment IV white, apical half dark brown. Legs: femora stramineous, basal half of mid and hind ones white; tibiae pale stramineous, fore tibiae on apex brown, tarsi white, apical segment(s) brown.   
 Measurements (in mm). Body length: 8.20. Head length: 1.28, width: 1.31, interocular space: 0.68. Pronotum length: 1.51, width: 2.02. Scutellum length: 1.48, width: 0.93, length of claval commissure: 2.57. Lengths of antennal segments: I 0.88, II 2.34, III 2.00, IV 2.33. Length of labium: 5.85, labial segments I 1.55, II 1.64, III 2.00, IV. 0.66.   
 Differential diagnosis. The greatly elongate labium (reaching abdominal segment V) is diagnostic for this species; labium of all other species does not surpass mid coxae. Body stramineous, contrary to the other known species which are much darker. Antennal segment IV with basal half white (all other species have much shorter white ring). Membrane with broad pale stripe and large apical pale spot, the other species have smaller pale spots and darker membrane.   
 Etymology. The species epithet is a Latin adjective, longirostris (= having long rostrum), because its labium is much longer than in any other known species of the genus.   
 Distribution. Indonesia: Sulawesi.
