Haitlinger, Ryszard & Šundić, Miloje, 2015, Abrolophus balkanicus sp. nov. from Montenegro, with redescriptions of A. stanislavae (Haitlinger, 1986) and A. wratislaviensis (Haitlinger, 1986) and notes on A. podorasensis (Haitlinger, 2007) (Acari: Erythraeidae), Turkish Journal of Zoology 39 (6), pp. 1018-1029 : 1026-1028

Abrolophus wratislaviensis ( Haitlinger, 1986)

Material examined. For measurements were used 19 specimens collected in the Czech Republic, Denmark, Estonia, Norway, Poland, Russia, Slovenia, Sweden, and Ukraine ( Haitlinger, 1986, 2000, 2003b, 2003c, 2008a, 2008b, 2010).

Diagnosis. Odontus and accessory claw not divergent, fD 42 (42–50), fV 16–18, Ta I 52–60, Ti III 52–70, IP 905– 1038.

Description. Larva. Dorsum with 42 (42–50) barbed setae. One pair of circular eyes (diameter 13 µm) on lateral scutum ( Figure 17 ). Scutum slightly longer than wide with pair of barbed scutalae and pair of sensillary setae. Anterior setae (AL) equal in length (in other specimens AL a little shorter than PL). Anterior sensillary setae (ASE) distinctly shorter than posterior sensillary setae (PSE), both with setules at distal half ( Figure 18 ).

Ventrum. Ventral side of idiosoma with setal pair 1a, 2a, and 3a, all slightly barbed. Between coxae I–II 4 setae, between coxae II–III 16 setae, and beyond coxae III 18 setae (16–19). Coxalae 1b> 3b> 2b, all mentioned setae slightly barbed ( Figure 19 ).

Gnathosoma. A pair of nude adoral setae cs, and a pair of club-shaped supracoxal setae (elcp). Ventrally two pairs of hypostomal setae nude as1 and slightly barbed as2 and barbed setae bs. Palpfemur with two setae, both slightly barbed. Palpgenu with 3 weakly barbed setae and palptibia with two nude setae and accessory claw. Palptibial claw not divergent ( Figure 20 ). Palptarsus with 7 nude setae (including eupathidium and solenidion) ( Figure 21 ).

Leg setal formula: Leg I: Ta 1ω, 1ε, 2ζ, 17; Ti 2φ, 1Κ, 13; Ge 1σ, 1Κ, 10; Tf 8; Bf 4; Tr 2; Cx 1 ( Figure 22 ). Leg II: Ta 1ω, 2ζ, 13; Ti 2φ, 11; Ge 1σ, 1Κ, 9; Tf 5; Bf 4; Tr 2; Cx 1 ( Figure 23 ). Leg III: Ta 1ζ, 11; Ti 1φ, 12; Ge 1σ, 9; Tf 5; Bf 4; Tr 2; Cx 1 ( Figure 24 ).

Distribution: Austria, Belgium, Bulgaria, Czech Republic, Denmark, Estonia, Great Britain, Holland, Italy, Latvia, Lithuania, Luxembourg, Moldova, Norway, Poland, Romania, Russia, Slovenia, Sweden, Switzerland, Ukraine ( Mąkol and Wohltmann, 2012).

Remarks. A. wratislaviensis belongs to the Abrolophus species group having palptarsus without comb-like seta or setae with long setules and odontus and accessory claw not divergent (or very slightly divergent). This group includes 7 species mentioned in the remarks about A. balkanicus . Comparison with A. balkanicus is given in the remarks for this species. It differs from A. norvegicus in the shorter W (46–56 vs. 68–84), AW (30–36 vs. 42–57), PW (40–55 vs. 62–80), PL (22–30 vs. 44–63), as2 (11–22 vs. 34–60), OD (13–17 vs. 18–33), and Ti III (52–70 vs. 84–108); from A. kazimierae in palpfemur without projection vs. palpfemur with projection; from A. viburnicola in fV (18 vs. 31), AW (30–36 vs. 42), AL (20–28 vs. 52), PL (22–30 vs. 45), ISD (44–54 vs. 63), shorter longest dorsal setae (35–53 vs. 80), 1b (26–36 vs. 48), 2b (18–23 vs. 33), and Ti III (52–70 vs. 80); and from A. baardi in the shorter L (57–72 vs. 80–90), W (46–56 vs. 56–62), AW (30–36 vs. 38–46), ISD (44–54 vs. 58–64), AL (20–29 vs. 54–68), PL (22–30 vs. 54–64), ASE (28–36 vs. 48–54), PSE (54–65 vs. 80–98), GL (99–111 vs. 120–130), 1a (24–33 vs. 46–54), 1b (26–36 vs. 50–58), 2b (18–23 vs. 28–36), PsFd (30–42 vs. 46–58), Ta I (42–60 vs. 68–78), and Ti III (52–70 vs. 114–1300).
