Distribution; OR, CA, NV, Baja California-Norte-MX

Information: the habitat that these beetles reside in is greatly variable, ranging from backyards of all sorts, to coastal beaches and forests, to barren deserts and fields away from human activity. {[DUE TO damage on the T.maculicolle specimen in our collections, we temporarily do not have a dorsal studio photograph of the species.]}

Description: elongate-ovate, semi-robust or slender (males tend to have slightly narrower elytra and pronota than the females), body glossy or semi-glossy. Head triangular; dark orange, to orange, nearly black; face relatively short. Occiput weakly constricted. Eyes reduced, but not strongly; the eyes weakly bulge laterally, and are slightly angled forward. Two supraorbital setae over each eye. Most of the surface of the head should be smooth; frons wrinkled, which continue onto the clypeus. The clypeus possesses two seta-bearing fovea, one on either lateral margin. Mandibles not particularly long, curved. Palpi yellow. First three-four segments of the antennae should be of a paler yellow or yellow-orange colouration than the rest of the antennae; antennal pubescence begins on the second antennomere following the pedicel (segment #4).  Pronotum ovate; relatively pale orange to pale yellow, typically with two brown, ovate macules on the disk--one on either side of the median line. Front margin rounded inward slightly; front angles round; lateral margins round, beaded; hind angles obtuse; basal margin sinuous, dorsal base should have a short series of vertical wrinkles. Median line strong, disk surfaces on either side of the median line should be weakly convex; the dorsal surfaces inside of the hind angles are rough, slightly depressed. Scutellum exposed. 8 well-defined striae per elytron, intervals flat; matte to semi-glossy brown in colour, with smokey to pale yellow "["-shaped margins margins. Humeral shoulders rounded-obtuse, laterobasal ridges entire, curved apically; lateral margins rounded; apices weakly sinuate. Parascutellar pores small. Aside from the 4 seta-bearing fovea found along the 3rd elytral interval (as seen in the third studio photo included), as well as the typical lateral setae found on most carabids, no elytral pubescence is present on this species. Ventral colouration semi-glossy piceous, limbs yellow.
