Tachinus er en gruppe (slekt) av biller som hører til underfamilien Tachyporinae i den store familien kortvinger (Staphylinidae). De er middelsstore, glatte og blanke, svarte biller med et stort og bredt brystskjold (pronotum) og et forholdsvis lite, rundt hode.
Utseende
Middelsstore (5-12 millimeter), litt brede, svarte og blanke kortvinger. Kroppen er blank og glatt, ofte med fin mikroskupltur men nesten helt uten hår og tydelig punktering. Dekkvingene kan være rødbrune eller ha gule flekker, og pronotum har ofte gul kant, ellers er de svarte. Hodet er forholdsvis lite og holdet gjerne litt nedbøyd slik at det ofte såvidt er synlig foran pronotum. Antennene er forholdsvis lange, uten tydelige børster, litt tykkere mot spissen men ikke kølleformede. Pronotum er hvelvet, nær halvsirkelformet sett ovenfra, uten påfallende børster. Dekkvingene er hårløse, men kan være litt matte på grunn av markert mikroskulptur. Bakkroppen er mer eller mindre jevnt avsmalnende bakover, i alle fall de bakerste leddene har noen lange og kraftige børster ved bakhjørnet. De bakerste rygg- og bukleddene varierer mye i formen og gir nyttige karakterer for å skille både kjønn og arter. Beina er middels lange, vanligvis rødlige på farge.
Levevis
Tachinus-artene er særlig knyttet til gjødsel og er derfor vanlige der det beiter husdyr. De lever ikke av selve gjødselen men av andre insekter, særlig fluelarver, som lever der. De flyr godt og kan ofte påtreffes flygende. Noen arter er vanlige i skog, men mange finnes først og fremst i kulturlandskapet.
Systematisk oversikt / norske arter
Det er beskrevet vel 150 arter totalt.

Measurements of female paratype: BL 4.89; FL 3.61; FL 3.61; PL 0.89; EL 1.67; SEL 0.28; HW 0.89; PW 1.45; EW 1.72; relative length of antennomeres I–XI: 23: 16: 16: 10: 13: 12: 12: 12: 10: 12: 26.
Body (Figs 1A, 1B) dark brown; mouthparts and elytra reddish brown; basal four antennomeres and legs reddish yellow.
Head shorter than wide, HW: PW = 0.58–0.62, disc with microsculpture consisting of irregular striae, punctation fine and sparse. Antennae moderately short, antennomeres X slightly shorter than wide.
Pronotum distinctly wider than long (PL: PW = 0.61–0.62); apical margin transversely concave, base slightly convex; surface with microsculpture consisting of irregular transverse striae, punctation slightly finer than that of head.
Elytra slightly elongate; EL: EW = 0.96; EL: PL = 1.73; EW: PW = 1.13 in male; EL: EW = 0.97; EL: PL = 1.88; EW: PW = 1.19 in female. Surface with microsculpture composed of fine meshes, punctation coarser than that of head.
Surface of abdomen with microsculpture radiating from punctures.
Male. Posterior margin of sternite VII (Figs 9A, 10A) broadly and deeply emarginate, apical margin bent ventrad, with moderately broad area of coarse granules. Tergite VIII (Fig. 11A) with four short lobes, median lobes slightly longer than lateral ones. Sternite VIII (Fig. 13A) broad. Median lobe of aedeagus (Fig. 15A) broad and projecting beyond apex of parameres, parameres fused, forming one apically truncate plate.
Female. Body (Fig. 1B) slightly larger than that of male. Elytra only slightly longer than in male; inner part of posterior margin produced, forming a distinct angle. Microsculpture more distinct than in male. Lobes of tergite VIII (Fig. 18A) completely reduced, posterior margin sinuate, lateral angles each with pair of long setae. Sternite VIII (Fig. 20A) with fimbriate median lobes fused and as long as sublateral ones.
