Ventral shield, L = 242 (242–260); posterior W = 480 (467–512), triangular, truncated posteriorly, surface shagreened (Fig. 17 C), with 12 pairs of small setae (Fig. 14 A). One pore underneath posterior margin of coxa IV. Metapodal-peritremal-exopodal shield (MPES) reticulated, with a pair of pores (Fig. 17 C) and a seta. Anal shield, L = 149 (149–164); anterior W = 416 (390–429), with five pairs of simple setae plus longer antero anal seta, aa, L = 31 (29–32), two pairs of pores, one near anterior margin, another below the anus.

Hypostomal setae hyp 1 longest, simple, L = 65 (62–65); hyp 2 medium length and barbed, L = 37 (36–40); hyp 3 short and slightly serrated, L = 15 (14–16) (Fig. 15 G). Chelicera with barbed seta, movable digit with four teeth, fixed digit with six teeth. Most palpal setae simple, except al 1 and al 2 on trochanter are branched and serrate respectively. Femur setae av 1 and pd 1 barbed, ad 1 serrated. Anterior margin of palp trochanter with blunt process (b) and denticulated process (s) (Fig. 15 H).

Leg IV: trochanter pv 1, pl 1 slightly serrated; femur av 1 barbed; genu av 1, pv 1 slightly barbed; tibia al 3 barbed; tarsus al 2 serrated. Seta pv 1 is large and slightly serrated, L = 29 (28–29) (Fig. 17 B).
Male (n = 10) Body oval, similar to female. Idiosoma, L = 896–960, W = 621–659 (Fig. 14 B).
Ve n tr al idiosoma. Tetartosternum, L = 34–47, anterior W = 118–124, shagreened, anterior margin round. Tetartosternal notch small, dividing anterior shield margin in two parts, stp 1 near posterior margin. Sternal shield shagreened and reticulated, L = 148 (143–152). Sternal seta st 1 simple, L = 16–19, st 2, st 3 and st 4, are microsetae and simple; shield with two pores, stp 2 near anterior margin, stp 3 close to genital opening. Genital opening oval, L = 56–62, W = 78–87. Ventral shield, L = 326–357, posterior W = 486–550, shagreened, reticulated only near anterior margin, with 26–32 setae and two pores, one at level of anterior margin of coxa IV, the other below coxa IV (Fig. 14 B). Anal shield shagreened, L = 140–161, anterior W = 397–429, with six pairs of simple setae plus longer antero anal seta, L = 28–37, with two pores, one near anterior margin and one below anus. Metapodal-peritremal-exopodal shield reticulated with a pair of pores, with seta.
Gnathosoma. Hypostomal seta hyp 1 long and simple, L = 62–68, hyp 2 barbed and intermediate, L = 37– 43, hyp 3 simple and short, L = 12–14.
Etymology. This species is named in honour of Oscar F. Francke who collected the many of the passalid beetles that carried Klinckowstroemiidae.
Remarks. This species can be distinguished from all others because setae st 1 and st 2 are microsetae, and st 3 is the longest of the sternal setae. The tetartosternal, sternal, mesogynial and latigynial shields are shagreened and reticulated. the medial margins of the latigynial shield are pointed, and there are four small simple setae on this shield. The mesogynial shield has a broad posterior margin and its apex is anteriorly pointed. The male has st 1 medium sized and simple, with a small tetartosternal notch that divides the anterior margin in two parts; the tetartosternum and sternal shield are reticulated and shagreened. The other sternal setae are microsetae. The ventral shield has 26–32 setae, but many of the specimenss have 28. Klinckowstroemia franckei is similar to K. multisetillosa because they have similar size (K. franckei L= 908,W=627; K. multisetillosa L= 936, W= 634), st 1 is simple, and the medial margin of the latigynial shield is pointed. However, the new species has only one pair of seta a, while K. multisetillosa has six pairs. Furthermore, the latigynial shield of K. franckei has four setae and is larger than that of K. multisetillosa, which has five setae. The posterior margin of the mesogynial shield is broader and more convex in K. multisetillosa than in K. franckei. The capitular seta is also small and simple in K. multisetillosa, but in K. franckei it is twice as long and serrated.
The beetles carrying these mites were found in decaying trunks at the same locality; it is possible that some specimens occupied the same trunk as a family group. Almost all mites were found in the alcohol in the vials where the beetles were collected. Three mites were found on the body: one on the mesoepisternum, one on the mesosternellum and another near to coxa III. Each mite was found on a different passalid.
