description: 26. Tylodinus rufus Luna-Cozar, sp. nov.
(Figures 98 d-e, 76-77, 119, 134)
Diagnosis. Length male, 2.8-3.3 mm, female, 2.7-3.9 mm. Width male, 1.3-1.5 mm, female 1.4-2.0 mm. As for T. complicatus with following exceptions: body approximately 2x longer than wide, clothed only with yellow and narrowly elongate scales. Punctures on rostrum longer than punctures on head, apical area smooth. Pronotum red, in lateral view strongly convex. Elytra with basal margin slightly sinuate (Figure 3), tubercles on I2 and I3 red, declivity base with tubercle on I4 distinctly longer than tubercle on I2; striae 10 incomplete, surface with or without granules. Male genitalia (Figure 98 d-e, 119) with median lobe moderately stout, apical process in lateral view abruptly curved downward. Female with sternite eight oblong, median membranous area as long as basal plate.
Comments. The punctures on the pronotum are evenly distributed, but sometimes smooth and glabrous areas are present in the middle of the disc, which is occasionally weakly carinate. Male genitalia in T. complicatus, T. rufus, T. noctis and T. dominicus are very similar; however, T. rufus is recognizable from its allies by the pronotum coloration.
Geographic distribution. México (Chiapas).
Habitat and elevation. Specimens were collected from leaf litter in high elevation cloud forest between 1900- 2950 m.
Derivation of specific name. Name derived from Latin rufus = red
