Tylodinus canaliculatus Champion 1905: 467 View in CoL , lam. 23, figs. 2, 2 a.; Blackwelder 1947: 860; O’Brien and Wibmer 1982: 139.

Diagnosis. Length male, 3.9–4.5 mm, female, 4.4–5.1 mm. Width male, 1.9–2.5 mm, female 2.1–2.4 mm. In addition to Champion’s description: As for T. triumforium with the following exceptions: rostrum with punctures large and deep. Pronotum weakly carinate. Female with ventrite 5 with large transversely ridged swelling. Male with ventrite 2 longer than 3–4 combined, ventrite 5 flat. Hind tibia with an external tooth.

Comment. The specimen from Tacaná, Chiapas has the scales more scattered and basal margin less sinuate than the specimens described by Champion. Females have a very distinctive transversely ridged swelling on abdominal ventrite 5.

Geographic distribution. Guatemala and México.

Habitat and elevation. Specimens were collected from leaf litter in cloud forest at 1800 m.

Derivation of the specific name. Champion (1905) did not indicate the derivation of the specific name canaliculatus , but it appears to be derived from Latin meaning channeled or grooved.

Material examined. Total 3 males, 3 females. Guatemala: Cerro Zunil, elev. 4000 ft. — 2 males, 3 females ( BMNH, syntypes); México: Chiapas, Unión Juárez , Volcán Tacaná , lower slopes, ca. 4 km N. Unión Juárez, elev. 1800 m (15°5'47.29''N, 92°5'17.04''W), 18.ix.1992, coll. R GoogleMaps . S. Anderson (92–108)— 1 male ( CMNC) .
