Description. FEMALE (holotype). Total body length 1070 (1015–1145 in 6 paratypes). Gnathosoma. Infracapitulum apunctate. Hypostomal apex with 1 pair of short protuberances. Each medial branch of peritremes with 4–5 chambers, each lateral branch with 17–18 chambers. Length of apunctate stylophore and movable cheliceral digit 240 (240–245) and 170 (170–180) respectively. Idiosoma. Propodonotal shield with deeply concave anterior margin, sculptured at lateral margins, bearing bases of setae vi, ve, si, c1 and se. Length ratio of setae vi:ve:si 1:2.2:2.9. Setae se and c1 situated at same transverse level. Setae si situated slightly anterior to level of setae c2. Hysteronotal shields clearly visible. Pygidial shield well sclerotized, triangular in shape. All terminal setae long, longer than 300. Genital setae g1 slightly (1.1–1.2 times) longer than g2, both shorter than aggenital setae ag1–ag3. Length ratio of setae g1:ag2 1:2.5–3.5. Setae ag1 not significantly (1.1 times) longer than ag2. Coxal fields I–IV apunctate. Setae 3c slightly (1.3 times) longer than 3b. Legs. Fan-like setae p’ and p” of legs III and IV with 16–17 tines. Setae tc” of legs III and IV 1.5 times as long as tc’III–IV. Apodemes I fused in anterior part of apodemes II.

Surface of propodonotal shield covered by minute punctations, bearing bases of setae vi, ve, si, se, and c1. Length ratio of setae vi:ve:si 1:2.2– 2.3:3.7–4. Setae se situated slightly anterior to level of setae c1. Setae si situated distinctly anterior to level of setae c2. Hysteronotal shield fused to pygidial shield, deeply concave on anterior margin, bearing bases of setae d1, f2 and h2, setae e2 located on or near this shield. Setae d2 2.8 times longer than e2. Setae h2 8 times longer than f2. Coxal fields I–IV apunctate. Setae 3c 1.7 times longer than 3b. Legs. Setae tc” of legs III and IV 1.6 times longer than tc’III–IV.

Type material. Female holotype and paratypes: 9 females, 3 males, 6 nymphs and 1 larva (AMU–SYR.331) from Margarops fuscatus (Vieillot); CENTRAL AMERICA, 19 March 1895, coll. C. Dalmas. Mites removed by M. Skoracki.
Type deposition. All material is deposited in the AMU, except 1 female in the ZSM and 2 females in the ZISP.
Etymology. The name mimidus refers to the family name of the host – Mimidae.
Differential diagnosis. This new species is morphologically similar to S. nitens Skoracki and Dabert, 2001 described from Malimbus nitens (Gray) (Ploceidae) from Togo (Skoracki & Dabert 2001). In females of both species, all terminal setae are long, genital setae are distinctly shorter than aggenital setae; setae si are situated slightly anterior to the level of setae c2, the hysteronotal shield is distinctly visible and the hypostomal apex is ornamented by one pair of protuberances. This new species differs from S. nitens by the following characters: in females of S. mimidus sp. nov., each branch of the peritremes has 21–22 chambers; the length of setae g1 is 80–90; fan-like setae p’ and p” of legs III and IV are with 16–17 tines; in males setae d2 are 2.8 times longer than e2. In females of S. nitens, each branch of the peritremes has 15–17 chambers; length of setae g1 is 55; fan-like setae p’ and p” of legs III and IV are with 6–9 tines; in males setae d2 and e2 are subequal in the length.
