Most leg setae simple, except: Leg I trochanter ad 1 and pl 1 serrate; femur pv 1 and pv 2 serrate; genu av 1, pl 1 and pv 1 serrate. Leg II: femur av 1 and pv 1 serrate; genu av 1 and pv 1 serrate; tibia pl 3 serrate. Leg III: femur av 1 serrate; genu av 1 and pv 1 serrate; tibia ad 3 serrate; tarsus ad 3 serrate. Leg IV genu pv 1 serrate; tarsus ad 3 serrate. Seta pv 1 on trochanter IV is large and serrate, L = 25 (20–25) ( Fig. 9 B). Male (n = 11) Body oval similar to female. Idiosoma, L = 627–691, W = 429–467 ( Fig. 7 B). Ve n tr al idiosoma . Tetartosternum, L = 31–37, anterior W = 78–87, shagreened ( Fig. 11 B).

Hypostomal seta hyp 1 simple, L = 43–53, hyp 3 finely serrate and intermediate in length, L = 21–33, hyp 2 is simple and shorter, L = 9–12,. Etymology. This species is named in honour of Alejandro Valdez, who helped to collect almost all the passalid beetles used in this research. Remarks. The latigynial shield of this species is long and wavy, st 1 is long and serrated; and sternal setae st 3 and st 4 are microsetae. All shields are shagreened. The mesogynial shield has wide anterior and posterior margins. The male has a very deep tetartosternal notch, almost 1/3 of the length of the shield, and 28 pairs of setae on the ventral shield. Klinckowstroemia valdezi is similar to K . montanoi and K . scotti because they have wavy medial margins on the latigynial shield, and the same number of setae on the anal shield. The new species can be separated from these two species because st 1 is long and serrated (L = 31–40), the others setae are microsetae and simple. Klinckowstroemia montanoi has st 1 slightly shorter and serrate (L = 21–29), the other sternal setae are short and simple. Klinckowstroemia valdezi is similar to K . scotti because they have 12 pairs of setae a on the ventral shield, but they differ because K . scotti has four pairs of setae on the hyaline hood and the latigynial shield has eight pilose setae, while K . valdezi has one pair of setae a and three simple setae on the latigynial shield. Klinckowstroemia valdezi is similar to K . montanoi because they have one pair of setae a on the hyaline hood and st 3 is a microseta, but K . montanoi has five to eight setae on the latigynial shield and st 1 (23.8) is moderate and serrate, while K . valdezi has three setae on the latigynial shield and st 1 is long (36) and serrate. The specimens were found in decaying trunks, on three beetle species and at different localities: two from the state of Hidalgo and one from the state of Veracruz. The mites were found in the alcohol, but in some cases these were found on the passalid’s body: one mite was on femur III, one on the episternum and another under the elytron. Two Klinckowstroemia species were found on two passalids: the larger K . victoriae (idiosoma ca. 850) and the smaller K . valdezi (idiosoma 563–710). One passalid specimen had three mite species: K . bifurcata , K . hunteri and K . valdezi .
