Cenophengus mboi sp. nov.

( Figs. 12–16 )

Etymology. The term mboi means black in the Hñähñu (Otomí) language, which is spoken in the valley of Mezquital, Hidalgo, Mexico. This term refers to the color of the body in this new species.

Diagnosis. Cenophengus mboi is similar in appearance to Cenophengus pedregalensis Zaragoza 1975 , but can be distinguished by the color of the body and terminal maxillary palpomere. In C. mboi the body is dark brown, whereas in C. pregalensis it is dark brown and the pronotum yellow-orange. Terminal maxillary palpomere is as long as the preceding three combined in C. mboi , in C. pedregalensis it is longer than the preceding three combined. The first tarsomere of the middle and hind legs are clearly longer than the second. In C. pedregalensis the two longitudinal excavations are near the center of the pronotum and the first and second tarsomeres of the middle and hind legs are of similar length.

Description, male. Total body length 9.6 mm; total body width 1 mm. Dark body ( Figs. 12, 13 ).

Head. Surface concave, as wider (0.8 mm) as long (0.8 mm) measured dorsally to exterior margins almost as wide (0.8 mm) as pronotum (1 mm), integument chagrined, coarsely punctuate, each puncture bearing a black seta; interantennal distance (0.1 mm), half of the length of 1 st antennomer; small eyes, hemispherical, finely faceted, longer (0.32 mm) than wide (0.14 mm); interocular distance greater than to the length of the eyes; long antennae (2.80 mm) extending slightly beyond the pronotal posterior margin; 1 st antennomere (0.25 mm) longer than the next two combined, 3 rd cup-shaped, 4 th to 11 th about equal in length (0.23 mm), 12 th (terminal) lanceolate (0.27 mm), antennal rami lanceolate, two times longer than respective antennomere; anterior border of frons concave; clypeus bilobed; terminal maxillary palpomere robust and securiform, as long as the preceding three combined (0.35 mm); terminal labial palpomere spindle-shaped (0. 15), three times longer than the preceding.
