Osoriellus tuxtlae View in CoL n. sp.

( Figs 66 View Fig A-C, 98B)

Type material: Holotype, male: Mexico: Chiapas, Tenejapa ca. 30 mi. ENE Tuxtla Gutierrez, 7000 ft. (92°22'W, 16°50'N), Dec. 31, 1972, leg. H. Frania ( AMNH). GoogleMaps

Paratypes: Mexico: 4 females, 4 males, with same data as holotype ( AMNH, UIC); GoogleMaps San Louis Potosi, Sierra de la Abra, Sotano de la Tinaja, flood debris on mud slope, 1500 ft. from entrance, female, Feb. 18, 1970, leg. J.A.L. Cook ( AMNH) GoogleMaps .

Diagnosis: The species can be differentiated from the species similar in size and absence of pronotal microsculpture, i.e. O. boliviensis , O. parumpunctatus , and O. minor , by the dense and coarse punctation. In O. tuxtlae the interstices are narrower than half of diameter of punctures, wheras in the other species the interstices between punctures are much wider than the diameter of punctures.

Description: Length: 4.6 mm. Colouration: Dark reddish to brown; head and pronotum brown; elytra lighter red; anterior abdominal segments light red; posterior segments dark red; legs and antennae yellow.

Head: 0.60 mm long, 0.82 mm wide; eyes not prominent; as long as temples; sides of fore-head sinuate; sides of clypeus approximately parallel; clypeal angles with granules; sparsely and deeply punctate with setiferous punctures; setae pointing to middle; impunctate areas at base of antennae and on central vertex; supraocular area with denser punctation than vertex; without microsculpture; surface shiny and polished.

Antennae with second antennomere oblong and thicker than third; third antennomere conical, narrower and shorter than second; following 3 antennomeres wider than long, but not wider than third antennomere; antennomere 7 quadrate; antennomeres 8 to 10 wider than long and distinctly wider than preceding antennomeres.
