Remarks. Hypermallus undulatus was described from Mexico (Trapiche). According to Selander and Vaurie (1962) it is not possible to know where Trapiche is placed in Mexico because there are several villages of this name in the country. Bates (1880) provided a single measure (5 ½ lin. = 11.65 mm ), suggesting that he had a single specimen. Even so, Chemsak (1967) designated a lectotype . Currently, the species is known from Mexico ( Veracruz , Oaxaca ), Honduras , Nicaragua , and Costa Rica ( Monné 2021 ). However, Bates (1885) also indicated that the species occurs in “Ventanas”, a place in the Mexican state of Durango (Selander and Vaurie 1962), and Hovore (2006) recorded Guatemala . The material examined expands the geographical distribution to the Mexican states of Quintana Roo and Yucatán . In the typical specimens, the general color in A. undulatus varies from brown to nearly black, the middle elytral pubescent macula may be very well-marked or not, and the distal pubescent macula on the elytra may be very well-marked, as in the lectotype (see photographs on Bezark 2021a ) or almost absent ( Fig. 29 ). At first glance, the female specimen from Yucatán ( Figs 29–33 ) appears to belong to a different species. This is because the general pubescence is sparser, the scutellum is glabrous, and the white maculae on the elytra are almost absent. However, I hypothesize that the specimen is just an extreme variation of the species. The prothoracic sculpturing is equal to that in the typical specimens, including that on sides of the prothorax ( Figs 33, 35 ), and the prothoracic and elytral maculae are in the same place, although are almost indistinct on the elytra. In side view, the female from Yucatán ( Fig. 31 ) also appears to be flatter than the typical specimens ( Fig. 34 ), but we believe this is also just a variation . FIGURES 29–39. 29–33) Anelaphus undulatus ( Bates, 1880 ) , female from Mexico (Yucatán): 29) Dorsal habitus; 30) Ventral habitus; 31) Lateral habitus; 32) Head, frontal view; 33) Prothorax, lateral view. 34–37) Anelaphus undulatus , female from Mexico (Quintana Roo): 34) Lateral habitus; 35) Prothorax, lateral view; 36) Dorsal habitus; 37) Ventral habitus. 38–39) Anelaphus subdepressus (Schaeffer, 1904) , female: 38) Prothorax, lateral view; 39) Dorsal habitus. Anelaphus undulatus is very similar to A. subdepressus (Schaeffer, 1904) , but differs especially by the sculpturing on the sides of the prothorax being somewhat coarser and sparser ( Figs 33, 35 ), and the sparser general pubescence, especially the white setae. In A. subdepressus ( Fig. 39 ), the sculpturing on the sides of the prothorax is slightly finer and denser ( Fig. 38 ), and the general pubescence is denser, especially the white setae.
