Cenophengus xiinbali sp. nov.

( Figs. 28–32 )

Etymology. The term “Aj xíinbal” means traveler in the Maya language. This species is named in honor of the South American migrant people who have gone missing or perished in the pursuit of a better life.

Diagnosis. Cenophengus xiinbali is similar in appearance to Cenophengus longicollis Wittmeri 1976 , but can be distinguished by the interocular distance and terminal maxillary palpomere. In C. xiinbali the interocular distance is 3.5 times longer than eye width, whereas in C. longicollis it is three times longer. The terminal maxillary palpomere is as long as the preceding three combined in C. xiinbali , whereas in C. longicollis it is longer than the preceding three combined.

Description, male. Total body length 8.3 mm; total body width 0.93 mm. Brown body, except for the pronotum, legs and last two abdominal segments, which are orange colored ( Figs. 28, 29 ).

Head. Surface concave, longer (0.8 mm) than wide (0.73 mm), measured dorsally to exterior margins thinner (0. 73 mm) than pronotum (0.93 mm), integument chagrined, coarsely punctuate, each puncture bearing an amber seta; interantennal distance half-length of 1 st antennomere (0.12 mm); small sized eyes, hemispherical, finely faceted, almost as long (0.33 mm) as wide (0.12 mm); interocular distance greater than eyes length (0.6 mm); antennae (2.4 mm) extending beyond pronotal posterior margin; 1 st antennomere (0.21 mm) as long as next two combined, 3 rd cup-shaped, 4 th in length (0.1 mm), 5 th to 11 th about equal in length (0.21 mm), 12 th (terminal) lanceolate (0.26 mm), antennal rami lanceolate, ramus two times longer than respective antennomere; anterior border of frons concave; clypeus bilobed; terminal maxillary palpomere securiform, as long as the preceding three combined (0.3 mm); terminal labial palpomere spindle-shaped, three times longer than the preceding (0.06 mm).

Thorax. Pronotum longer (1.14 mm) than wide (0.93 mm); tegument chagrined, coarsely punctuate; each puncture bearing an amber seta, convex disc, with one longitudinal excavation on each side of the midline, anterior border concave, posterior border almost straight with a middle notch, lateral margins almost parallel, anterior angles rounded and posterior angles acute; scutellum almost quadrangular, posterior border truncated, shiny integument, thickly dotted, each puncture with a black seta; elytra almost four and a half times as long (2.68 mm) as wide (0.64 mm), convex; hindwings with radial cell closed, r3 vein absent, r4 vein reduced, the posterior radial vein (RP) reduced (length less than half the size of the vein MP1+2), medial field containing six main veins: MP3, MP4, CuA1, CuA2, CuA3+4, and AA 3+4; CuA and AA well marked and cubitoanal cell closed, AP3+4 long.; 1 st and 2 nd tarsomeres of prothoracic legs about equal in length, 1st tarsomere of meso- and metathoracic legs longer than 2nd.

Abdomen. Integument shiny, punctured, densely setose, penultimate sternite with posterior margin sinuate, last sternite cleft. Aedeagus: with three teeth at the apex of paramere ( Figs. 30–32 ).
