Etymology. This species is named in honour of Alfonso Ballesteros, who helped to collect almost all the passalid beetles used in this research.
Remarks. This species can be distinguished from all others because the sternal setae are long and serrated, and seta st 1 is the longest. In females the tetartosternal and sternal shields are shagreened and reticulated, and the other shields are only shagreened. The latigynial shield with has four or five simple setae. The mesogynial shield is broad posteriorly, and the form of the tetartosternal shield is very different to others species. In the male st 3 and st 4 long and serrated, and the tetartosternal, sternal, ventral and anal shields are shagreened. The tetartosternal notch is small, V-shaped, and divides the anterior margin in two parts. The ventral shield has 17 pairs of setae. Klinckowstroemia ballesterosi is similar to K. santibanezi and K. candidoi because they have setae a 1 and st 1 long and barbed, but the new species is smaller (896–1088 versus 1164– 1517 and ca. 1290 respectively), and all sternal setae are serrated and long, with fourto five simple setae on the latigynial shield. In contrast, in K. santibanezi the sternal setae are barbed and serrated, and there are eight serrated setae on the latigynial shield; and in K. candidoi the sternal setae are serrated and simple and there are three to four simple setae on the latigynial shield. Klinckowstroemia ballesterosi has more setae on the ventral shield (K. ballesterosi 14, K. santibanezi 11–14, K. candidoi 11). In K. ballesterosi the tetartosternum and sternal shield are reticulated, while in K. santibanezi and K. candidoi the ventral and anal shields are reticulated.
The beetles carrying this species were found in decaying tree trunks in two different states of Mexico. In Veracruz they were found on Odontotaenius zodiacus and almost all specimens were found in the alcohol, with only one specimen on the humerus of one of the beetles. From Oaxaca it was found with Petrejoides recticornis free in the alcohol.
