description: Klinckowstroemia oconnori sp. nov.   
 Female (n = 3)   
 Body oval. Idiosoma: L = 781 (781–806); W = 576 (563–576) (Fig. 7 A). Gnathosoma with different hypostomal setae: hyp 1 long and simple, L= 50 (47–54); seta hyp 2 long and serrated, L = 43 (40–43), seta hyp 3 medium and serrated, L = 16 (12–16), and seta hyp4 medium-sized and serrated, L = 16 (9–16).   
 Chelicera with excrescences, movable digit with four teeth and fixed digit with seven teeth. Palp setae are simple, but av 1 and av 2 on trochanter are branched and serrated, respectively; on femur pd 1, pd 2, and pv 1 are serrated. On genu the setae al 1, al 2, ad 1, pl 1, pd 1 and pv 1 are serrated.   
 Hyaline hood extending to level of coxa I, seta a 1 moderate and simple, L = 19 (19–22). Tritosternum base wider than long. Presternal (Pst) L = 37 (34–37), anterior W= 105 (102–109) shagreened and with line near the posterior margin; near posterior margin is a lyriform sternal pore stp 1. Presternal notch is a small concave depression. Sternal seta st 1, L = 53 (34–53), serrated (Fig. 7 A).   
 Sternal shield L = 59 (56–62), shagreened, with some reticulations (Fig. 7 A). Lyrifissure stp 2 near to anterior margin of the shield; st 2, L = 47, serrated, below. Sternal setae st 3, L = 37, and st 4, L = 40, both setae are large and serrated, and near to posterior margin of the shield. Intact sternal setae present in only one specimen.   
 Sternogynal shield (SgS), L = 68 (62–68); W = 158 (140–158) triangular and shagreened, posterior margin straight and slightly pointed, near to anterior margin is pore stp 3. Sternogynal apodeme thin and short. Latigynal shields shagreened, L = 130 (127–130); W = 65 (62–65), each with an oval pore and four simple setae, medial margin of shield straight. Mesogynal shield, L = 62 (59–62); W = 83. 7, triangular and shagreened, posterior margin wider and slightly pointed at apex. Mesogynal condyles extending almost to level of shield apex.   
Ventral shield, L = 171 (171–189); posterior W = 419 (403–419), shield triangular and shagreened, truncated posteriorly, with ten pairs of small setae (Fig. 7 A), with two pairs of pores at the level of posterior margin of coxa IV. The metapodal-peritrematal-exopodal shield (MPES) shagreened, with one pair of pores and one simple seta.  
Anal shield, L = 140 (124–140); anterior W = 341 (316–341), with 4 pairs of simple setae plus longer anteroanal seta, L = 22 (22–25); two pairs of pores, one near the anterior margin, and the other below the anus (Fig. 7 A).  
 Serrate setae on leg I are: trochanter ad 1, al 1 and pv 1; femur: av 3, pv 1 and pv 2; tibia ad 1, ad 2, ad 3, av 1, av 2, pl 1, and pl 2. Serrate setae on Leg II are: femur pv 1; genu pv 1. Serrate setae on leg III: trochanter ad 1 and ad 2; femur av 1; genu av 1, and pv 1; tibia ad 4; tarsus ad 3, and pl 1. Serrate setae on leg IV: femur av 1; genu av 1, and pv 1; tibia ad 4, and al 4; tarsus ad 2 and ad 3 serrated. Seta pv1 of the femur IV large L= 28 (27–28).   
 Male (n = 5)   
 Body oval, similar to female. Idiosoma L = 742–806, W = 493–563 (Fig. 7 B). Presternal (Pst) L = 31–37, anterior W = 102–109, presternal notch V-shaped, shagreened and with one line near anterior margin (Fig. 8 B) as in female; near to posterior margin is a lyriform sternal pore stp 1. Sternal seta st 1, L = 40–56, long and serrated (Fig. 8 C). Sternal shield shagreened (Fig. 8 D) and reticulated (Fig. 8 E), L = 121–127, with two pores, one near the anterior margin (stp 2) and other near the genital opening (stp 3). Sternal seta st 2 long and serrated, L = 48–50; sternal seta st 3 long and serrated, L = 39–47; sternal seta st 4 medium and serrated, L = 20–33. Genital opening oval, L = 50–62, W = 68–71. Ventral shield shagreened and reticulated, L = 264–285, W= 372–450 (Fig. 8 H), with 30 setae and two pores, one above the anterior margin of coxa IV, and other below coxa IV. Anal shield L = 102–140, anterior W = 322–363 (Fig. 8 G); with four pairs of simple setae plus longer antero-anal seta, L = 12–25, with two pores: one near the anterior margin and another below the anus. Hypostomal setae (Fig. 8 A): hyp 1 long and simple, L = 43–56; seta hyp 3 serrate and long, L = 32–43; seta hyp 2 simple and shorter, L = 11–12. Anterior margin of trochanter palp with blunt process (b) and spine-like process (s) (Fig. 8 F).   
 Diagnosis. The sternal shield in both sexes is reticulated, all sternal setae on the female are long and serrated, and the sternogynal shield extends posteriorly to the mesogynal shield. Males have sternal setae s t 1, st 2, and st 3 long and serrated, and seta st 4 medium and serrated.   
 Remarks. Klinckowstroemia oconnori sp. nov. is similar to K. montanoi Villegas-Guzman et al. because in both sexes the sternal shield is reticulated, but K. montanoi has sternal setae simple and short, in both sexes, whereas K. oconnori has sternal setae long and serrated. K. oconnori is similar to K. ballesterosi because both species have sternal setae long and serrated, but the sternal shield in K. ballesterosi is shagreened, whereas on K. oconnori it is reticulated, and K. oconnori (L= 781–806, A= 563–576) is smaller than K. ballesterosi (L= 896–1088, A= 640–774).   
 Etymology. This species is named name in honour of Barry M. OConnor who collected the passalid hosts of this species and gave us the mites.   
 Material examined. From Odontotaenius striatopunctatus: holotype Ƥ, and 2 33 paratypes from Panama, Panama, Cerro Azul 950 m, 6 May 1991,B. M. OConnor; mites were found in the alcohol. From Petrejoides subrecticornis 2Ƥ and 2 33 paratypes from Panama, Panama, Cerro Azul 950 m, 6 May 1991, B. M. OConnor; mites were found in the alcohol. Holotype female, and 3 paratypes males deposited in NMNH, one female (CNAC 006746) and a male (CNAC 006747) paratypes are deposited in CNAC. One female was lost when it was being prepared for scanning electron micrographs, but this specimen was considered for description.   
 Ecology. Specimens were found on two species of passalid beetles. The beetles were probably found in the same log, because they were collected at the same locality and on the same day; perhaps, for this reason they share the same species of mites
