Idiosoma  . Propodonotal shield with deeply concave anterior margin, sculptured at lateral margins, bearing bases of setae vi, ve, si, c 1 and se. Length ratio of setae vi:ve:si 1: 2.2: 2.9. Setae se and c 1 situated at same transverse level. Setae si situated slightly anterior to level of setae c 2. Hysteronotal shields clearly visible. Pygidial shield well sclerotized, triangular in shape. All terminal setae long, longer than 300. Genital setae g 1 slightly (1.1–1.2 times) longer than g 2, both shorter than aggenital setae ag 1 –ag 3. Length ratio of setae g 1:ag 2 1: 2.5–3.5. Setae ag 1 not significantly (1.1 times) longer than ag 2. Coxal fields I –IV apunctate. Setae 3 c slightly (1.3 times) longer than 3 b. Legs.

Setae d 2 2.8 times longer than e 2. Setae h 2 8 times longer than f 2. Coxal fields I –IV apunctate. Setae 3 c 1.7 times longer than 3 b. Legs. Setae tc” of legs III and IV 1.6 times longer than tc’III –IV. Lengths of setae: vi 55–65, ve 125–140, si 220–240, se 220–235, c 1 200, d 1 25, d 2 70, e 2 20 –25, f 2 25, h 2 200, ag 1 80–100, ag 2 40–60, ag 3 65, tc’III – IV 40, tc” III –IV 65, 3b 60, 3c 100, lR’III 70, l’RIV 60.

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 c 2, 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 g 1 is 80–90; fan-like setae p’ and p” of legs III and IV are with 16–17 tines; in males setae d 2 are 2.8 times longer than e 2. In females of S.

nitens  , each branch of the peritremes has 15–17 chambers; length of setae g 1 is 55; fan-like setae p’ and p” of legs III and IV are with 6–9 tines; in males setae d 2 and e 2 are subequal in the length.
