Description. Labium reaching mid coxae. Fore femur with three (sometimes four) spines and long hairs. Hind tibia with hairs and ¿ne spines; hairs shorter than spines, spines shorter than diameter of tibiae. Male pygophore: see Fig. 14 ; paramere: see Figs 12 í13.

Colouration. Body blackish brown (Fig. 9). Narrow fascia along hind margin of pronotum, apex of scutellum (sometimes also posterior half of lateral margin of scutellum) and basal half of endocorium pale stramineous. Corium with tiny transverse arched pale stripe behind clavus close to apical margin and with large subapical pale spot continuing in darker pruinose part which reaches apical margin. Pale part of subapical spot nearly triangular, on costal margin at least 2 times longer than dark apical part. Membrane dark ( Fig. 4 ), with two small spots (at apex of corium and a transverse one at level of hind border of subapical corial spot) and large apical whitish crescent spot. Antennal segment I dark brown, segments IIíIII pale brown, apically darker, segment IV blackish brown, basal 1/5í1/4 white. Fore femur blackish brown, inner part apically pale, mid and hind femora basally white, apically dark brown (with dark brown streak on basal part), fore and mid tibiae dark in variable extension, hind tibia with about basal 2/3 dark and pale stramineous apex, tarsi white, apical segment blackish. Measurements (in mm). Body length: 7.82í8.11. Head length: 1.32í1.34, width:

(Orig. K. Varga). tum length: 1.48í1.52, width 1.95í2.00. Scutellum length: 1.25í1.36, width: 1.95í1.10, length of claval commissure: 2.25í2.37. Lengths of antennal segments: I 0.87í1.10, II 2.65í2.77,

III 2.12í2.20, IV 2.45í2.54. Length of labium: 2.89í3.24, labial segments: I 0.88í1.00, II

0.91í1.00, III 0.66í0.77, IV 0.44í0.47.

Differential diagnosis. The labium of T. celebensis sp. nov. is longer than that of T. prolixicornis . Fore femur is armed with at least three spines in contrast to both previous species.

Scutellar margin is pale in apical half (other species have only the scutellar apex pale).

Colouration of antenna and corium is similar to that of T. redeii sp. nov. except for the shorter pale part of segment IV. The membrane is darker, having only two pale stripes in its basal half and a large apical crescent-shaped spot. Hind tibiae bicolorous, while previous species have unicolorous pale or brown hind tibiae. Ratio of antennal segments rather similar to T.

prolixicornis, strongly different from T. redeii (III: I 2.0í2.3; III: IV 0.8í0.9).

Etymology. The species is named after the distribution of the type series in Celebes Island.

Distribution. Indonesia: Sulawesi.
