Ventral shield, L = 211 (195–220); posterior W = 422 (416–435), shield triangular ( Fig.8 View FIGURE 8 D), truncated posteriorly, surface shagreened and reticulated, with 13–14 pairs of small setae ( Fig. 5 View FIGURE 5 A). One pore underneath posterior margin of coxa IV. Metapodal-peritremal-exopodal shield with a pair of pores and one simple seta. Anal shield ( Fig.8 View FIGURE 8 E), L = 124 (105–140); anterior W = 352 (320–365), with five pairs of simple setae plus longer anteroanal seta, L = 25 (20–25), two pairs of pores, one near anterior margin and the other below anus.

Male (n = 5) Body oval, similar to female. Idiosoma, L = 704–755, W = 474–518 ( Fig. 5 View FIGURE 5 B).

Ve n tr al idiosoma. Tetartosternum, L = 40–56, anterior W = 93–124, shagreened. Tetartosternal notch deep, V-shaped. Sternal seta st 1, L = 20–22, simple. Setae st 2, st 3 and st 4 are simple microsetae. Sternal shield shagreened and reticulated ( Fig. 5 View FIGURE 5 B), L = 78–81. Genital opening oval, L = 43–47, W = 71–78. Ventral shield, L = 279–285, posterior W = 384–403, shagreened, with 24–26 setae ( Fig. 5 View FIGURE 5 B), with two pores, one at level of coxa III and other below posterior margin of coxa IV. Anal shield, L = 124–127, anterior W = 333–352, with five pairs of simple setae plus longer antero anal seta, L = 24–25, with two pores, one near anterior margin and the other below anus.

Gnathosoma . Hypostomal seta hyp 1 long and simple, L = 47–50, hyp 3 serrate, L = 31–34, hyp 2 simple and shorter, L = 16–25.

Etymology. This species is named in honour of Héctor Montaño, who helped to collect almost all the passalid beetles used in this research.

Remarks. This species can be distinguished from all others because st 4 is a microseta, st 2 and st 3 are short and simple, st 1 is moderate and serrate and the medial margin of the latigynial shield is wavy. The sternal, latigynial and sternogynial genital shields are shagreened and reticulated, the tetartosternum is only shagreened. The mesogynial shield is wider in the anterior and posterior margins. In the male the tetartosternal notch is deep and distinct, V-shaped, almost reaching half the length of the shield, and there are 24–26 pairs of setae on the ventral shield. Klinckowstemia montanoi is similar to K. scotti and K. valdezi because all the species have wavy medial margins on the latigynial shield, st1 serrated, and number of setae on anal shield is equal. Klinckowstroemia montanoi (735.6) is longer than K. valdezi (685.9), but shorter than K. scotti (1292) . The latigynial shield has eight pilose setae in K. scotti , while K. montanoi have five to eight simple setae simple and K. valdezi has three simple setae. K. montanoi has 13–14 pairs setae on the ventral shield, while K. valdezi and K. scotti have 12 pairs.

The specimens were found in decaying trunks only in one locality in the state of Oaxaca, Mexico, on the same host, Ve r re s aff. intermedius . Mites were found in the alcohol, not on the beetles.
