(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.
