Syringophiloidus microcerculus Sikora and Skoracki  sp. nov.

( Figs 1–6View FIGURES 1 and 2View FIGURES 3 – 6)

Description. FEMALE (holotype, 9 paratypes). Total body length 570 (560–655). Gnathosoma  . Infracapitulum apunctate. Each medial branch of peritremes with 2–3 chambers, each lateral branch with 8–9 chambers with striae ornamentation. Stylophore 145 (145) long. Movable cheliceral digit 115 (115–120) long. Idiosoma  . Propodonotal shield weakly sclerotized, striae visible, apunctate. Length ratio of setae vi: ve: si 1: 1: 2–3. Propodonotal setae thin and with delicate ornamentation. Setae c 1 slightly (1.2 times) longer than d 2. Hysteronotal shield weakly sclerotized, not fused to pygidial shield. Pygidial shield reduced to small shield bearing bases of terminal setae (f 1, f 2, h 1 and h 2). Setae d 2 1.1–1.2 times longer than e 2. Setae f 1 and h 1 subequal in length. Genital plate absent. Both pairs of genital setae subequal in length. Length ratio of setae ag 1: ag 2: ag 3 1: 1: 1.3. Setae ps 1 and ps 2 subequal in length. Coxal fields I–IV sparsely punctate. Setae 3 c 2.3–2.7 times longer than 3 b. Legs. Fan-like setae p’ and p” of legs III and IV with 7–8 tines. Setae tc”III–IV 1.6–1.7 times longer than tc’III–IV. Lengths of setae: vi 15 (15), ve 15 (15), si 35 (35–70), se 200 (195–205), c 1 (190–205), c 2 180 (160–175), d 1 (130–150), d 2 170 (145), e 2 140 (125– 140), f 1 15 (15), f 2 185 (200–220), h 1 15 (15), h 2 315 (270–305), ps 1 15 (15), ps 2 15 (15), g 1 25 (20–25), g 2 25 (20–25), ag 1 125 (125–130), ag 2 (120–140), ag 3 165 (155–160), tc’III– IV 35 (35–40), tc” III–IV 55 (55–65), 3 b (30–35), 3 c (80), l’RIII 40 (40–50), l’RIV 40 (35–40).

MALE. Not found.

Type material. Female holotype and 15 female paratypes from Microcerculus  marginatus (Sclater); BRASIL, Para, Peixe-Boi, 5 May 1910, coll. L. Müller. Mites removed by M. Skoracki.

Type deposition. All type material is deposited in the AMU (AMU–SYR. 349), except 2 female paratypes in the ZISPAbout ZISP ( ZISPAbout ZISP AVB 011- 2908 -002) and 2 female paratypes in the ZSMAbout ZSM ( ZSMA 20112001).

Etymology. The specific name microcerculus  is taken from the generic name of the type host and is a noun in apposition.

Differential diagnosis. S. microcerculus  sp. nov. is morphologically similar to S. sialius Skoracki, Flannery & Spicer, 2009  described ex Sialia mexicana Swainson  ( Passeriformes  : Turdidae  ) from USA ( Skoracki et al. 2009). In females of both species each medial branch of the peritremes has 2–3 elongated chambers, setae si are distinctly longer than vi; setae vi and ve are subequal in the length; hysteronotal setae (d 1, d 2 and e 2) are subequal in length; the propodonotal shield is punctate; aggenital setae ag 1 and ag 2 are subequal in length. This new species differs from S. sialius  by the following characters: in females of S. microcerculus  , the infracapitulum is apunctate; each medial branch of the peritremes has 8–9 chambers; length of the stylophore is 145; propodonotal setae vi, ve and si are with delicate ornamentation; length of setae si is variable but no longer than 65; the hysteronotal shield is weakly sclerotized and the cuticular striae are visible; the coxal fields are sparsely punctate. In females of the S. sialius  , the infracapitulum is punctuate; each medial branch of the peritremes has 11–12 chambers; length of the stylophore is 165–170; propodonotal setae vi, ve and si are smooth; length of setae si is 145–180; the hysteronotal shield is well sclerotized and the cuticular striae are invisible; the coxal fields are densely punctate.
