Diagnosis. Bonzia flechtmanni sp. nov. differs from all species of this genus by having the dorsal setae f1 and f2 on the hysterosomal shield ( Fig. 6 ). Bonzia flechtmanni sp. nov. resembles Bonzia yunkeri Smiley (1992) and Bonzia woodi Smiley (1992) by the presence of a smooth trichobothrium on tibiae IV, but is distinguished from B. yunkeri by having the dorsal setae f1 and f2 on the hysterosomal shield, seven sts on basifemora II, no sts on basifemora IV, five sts on telofemora I and II, four sts on genua I and II, and 20-22-18-18 on tarsi I-IV respectively. It can be distinguished from B. woodi by having the dorsal setae f1 and f2 on the hysterosomal shield, smooth dorsal setae, two sts on coxae IV, 2–3 sts on basifemora III–IV respectively, 4-4 sts on genu I–II respectively, and 20-22-18-18 on tarsi I-IV respectively.

Female. (n=6) Idiosoma 271 (262–282) long, 185 (180–192) wide.

Gnathosoma . ( Fig. 7 A–C) Subcapitulum. ( Fig. 7 A). 123 (120–127) long and with 4 pairs of setae (hg1–4); hg1 geniculate. Palp. ( Fig. 7 B). 102 (100–105) long, 5-segmented. Dorsal multi-branched seta present on the telofemora. Chaetotaxy: trochanter 0; basifemora 1 dorsomedial sts; telofemora 1 dorsal multi-branched; genua 2 dorsal and 2 ventral sts; tibiotarsi with 2 dorsal and 3 ventral sts and 1 tubercle. The tibiotarsi ends in a claw. Chelicera. ( Fig. 7 C). 115 (112–120) long, slender distally, integument granulated dorsally on the basal portion, each one with a narrow claw; dorsal setae absent.

Dorsum. ( Fig. 8 A). Apparently covered by a single shield with dense dot like striations. Propodosomal setae as well 2 pairs of setose trichobothria, at and pt, and tactile setae c1, c2, d1, e1, f1 e f2 present on shield. Setae h1 on integument. Setae h2 located laterad to anal region. Setae lps, mps, c1, c2, d1, e1, f1, h1, h2 simple. Setal lengths are as follows: at 149 (145–153), pt 138 (137–141) lps 41 (40–42), mps 73 (70–80), c1 73 (67–80), c2 53 (50–60), d1 86 (81–95), e1 85 (84–87), f1 78 (75–88), f2 26 (21–29), h1 49 (47–52) and h2 24 (20–27). Cupule im, between e1 and f1.

Venter. ( Fig. 8 B). Partially covered by clearly demarcated plates. Coxal plates I and II fused with 6 pairs of setae; coxal plates III and IV fused. Coxae I–IV setal formula 3-2-3-2. Genital plates weakly sclerotized with 4 pairs of setae (g1–g4) and 2 pairs of papillae. Integument between coxal and genital shields with 4 pairs of setae. Anal region with pair of anal setae. Cupule ih laterad to posterior edge of genital shield.

Legs. ( Fig. 9 A–D). Leg I 232, leg II 204 (200–207), leg III 213 (208–225), leg IV 245. Chaetotaxy: trochanters I-IV, 1-1-2-1; basifemora I-IV, 5-7-2-0; telofemora I-IV, 5-5-4-3; genua I with 4 ats, 5 sts; genua II 2 ats, 5 sts; genua III with 1 bsl, 5 sts; genua IV with 2 ats, 5 sts; tibiae I with 2 ats, 5 sts; tibiae II with 1 bsl, 5 sts; tibiae III with 1 bsl, 5 sts; tibiae IV with 1 smooth T, 4 sts; tarsi I with 1 lbls, 1 bsl, 1 ats, 1 dep (depression with peg-like setae), 1 dtsl, 20 sts; tarsi II with 1 lbsl, 1 dtsl, 22 sts; tarsi III with 21 sts; tarsi IV with 18 sts.

Male and developmental stages. Unknown.

Etymology. The specific name honours an eminent Brazilian Acarologist, Dr. Carlos Holger Wenzel Flechtmann, in recognition for his contributions to Brazilian and worldwide Acarology.
