( Figures 80–81 View FIGURES 76–83 , 121 View FIGURES 120–129 , 135 View FIGURES 134–135 )

Diagnosis. Length male, 2.5–2.8 mm, female, 3.0 mm. Width male, 1.2–1.4 mm, female 1.6 mm. Body approximately 2.0x longer than wide, black. Head with dark brown scales; vertex with patch of yellow scales on middle of vertex, dense to contiguous; frons moderately concave; rostrum moderately robust, moderately carinate, apical area puncticulate; eyes moderately convex. Pronotum in lateral view strongly convex, outline with anterior constriction, without posterior constriction ( Figure 10 View FIGURES 1–11. 1–5 ); in dorsal view with sides slightly divergent from base to midlength, then convergent to apex, constricted beyond middle; disc with longitudinal impression; surface with dense and deep punctures on flanks, becoming smaller, scattered towards middle, with yellow to light brown scales, very dense on lateral area and flanks, anterior area forming a thick longitudinal fringe along middle and narrow strip that diverges from middle base to flanks, and with dark scales on the middle and posterior areas of disc ( Figure 14 View FIGURES 12–19. 12 ); surface without granules. Elytra with basal margin slightly sinuate ( Figure 3 View FIGURES 1–11. 1–5 ); tubercle distribution as follows: I2 with small, round tubercle on declivity base, I3 with two tubercles: first subbasal, second on middle of elytra, I4 with two small tubercles, first between tubercles on I3, second on declivity base, longer than tubercle on I2 (but in some specimens of equal size), I5 with two small tubercles in same position as tubercles on I3, tubercles on I3 longer than other tubercles, I6 with subbasal tubercle; surface without granules. Metasternum flat, median section glabrous; metasternal tooth absent. Male abdomen with ventrites 3–5 in same plane as ventrites 1–2, ventrite 1 weakly concave, glabrous at median section; ventrite 2 feebly concave, as long as ventrites 3–4 combined, with transverse line of scales along middle; ventrite 5 longer than ventrite 1, flat, with anterior impression. Femora armed, hind femur length reaching elytral apex, middle and hind tibiae subparallel, premucro absent. Male genitalia ( Figure 121 View FIGURES 120–129 ) similar to that of T. rufus . Female with sternite eight trapezoidal, median membranous area ½ as long as basal plate length, spermatheca very shallowly curved.

Comments. Male genitalia in T. complicatus , T. rufus , T. noctis and T. dominicus are very similar; however, T. noctis is distinguished from its allies by body coloration

Geographic distribution. México (Chiapas).

Habitat and elevation. Specimens were collected from leaf litter in mixed cloud forest between 1500–1900 m.

Derivation of specific name. Name derived from Latin word noctis = night
