Measurements of female holotype: BL 4.63; FL 3.90; PL 1.07; EL 1.80; SEL 0.34; HW 0.93; PW 1.61; EW 1.78; relative length of antennomeres I-XI : 16: 9: 10: 6.5: 10: 8: 9: 9: 8.5: 8.5: 16. Body (Fig. 8A) dark brown to black; margins of elytra, mouthparts, basal four antennomeres and legs paler brown. Head slightly transverse, HW: PW = 0.58, surface almost without punctation, microsculpture consisting of irregular striae. Antennomeres X only slightly shorter than wide. Pronotum: PL: PW = 0.67; surface only with very fine and sparse punctation, microsculpture consisting of irregular, mostly transverse striae. Elytra elongate, EL: EW = 1.01, EL: PL = 1.68, EW: PW = 1.11; inner part of posterior margin distinctly produced, forming a distinct angle. Surface of elytra with uneven and sparse punctation, microsculpture distinct, consisting of fine rhomboid or somewhat transverse meshes. Abdomen with microsculpture consisting of transverse striae, punctation moderately coarse and dense. Male. Unknown. Female. Posterior margin of tergite VIII (Fig. 18I) sinuate, without obvious median lobes, but with short acute lobes at lateral angles, each with one pair of long setae. Sternite VIII (Fig. 20I) with fimbriate median lobes nearly fused; sublateral lobes as long as median ones. Remarks. Females of this species are distinguished from those of all other species by the slender habitus with exceptionally elongate elytra; from all species except the similar Tachinus armatus and Tachinus parahercules by the shape of tergite VIII.
