Abrolophus balkanicus sp. nov.

Material examined. Holotype larva and five paratype larvae, Vitoja, 15 km east of Podgorica , June 2012, Montenegro, one paratype, Tuzi, June 2012, one paratype, Bijelopavlići n. Podgorica; all off hosts on grasses, collected by M Šundić. The holotype is deposited in the Museum of Natural History of Podgorica, Montenegro, and six paratypes are deposited in the Museum of Natural History , Wrocław University of Environmental and Life Sciences, Wrocław, Poland.

Diagnosis. fD 48 (45– 48 paratypes), fV 20 (18-20), palpfemur with projection, odontus and accessory claw not divergent, Ta I 54 (51–58), Ti III 74 (70–79), IP 964 (950–1026).

Description. Larva (n = 8)

Dorsum. Idiosoma with 48 distinctly barbed dorsal setae (45–48 in paratypes). Eyes posterolateral to scutum, circular, not on platelets, 13 µm in diameter ( Figure 1 ). Scutum longer than wide, with two pairs of barbed scutalae, AL> PL in holotype (longer, shorter, or equal in paratypes). Anterior sensillae (ASE) distinctly shorter than posterior sensillae (PSE), both with setules on their ½ distal part ( Figure 2 ).

Ventral side of idiosoma. Sternal setae 1a, 2a, and 3a all barbed. Four setae between coxae I and II, 10 setae between coxae II and III, and 20 behind coxae III (18–20 in paratypes); all these setae barbed. Setae 1b> 3b> 2b; all setae barbed ( Figure 3 ). NDV = 68 (64–68 in paratypes).

Gnathosoma. Dorsally with adoral nude setae cs and supracoxal peg-like setae elcp. Ventrally a pair of short and nude setae as1, longer setulose setae as2, and setulose setae bs ( Figure 4 ). Palpfemur with projection having rounded tip and two setulose setae. Palpgenu with two barbed setae and one nude seta, palptibia with two nude setae and a narrow accessory claw. Odontus and accessory claw not divergent. Palptarsus with 8 nude setae (including eupathidium and solenidion) ( Figure 5 ).

Leg setal formula: Leg I: Ta 1ω, 1ε, 1Cp, 2ζ, 19; Ti 2φ, 1Κ, 12; Ge 1σ, 1Κ, 10 (11); Tf 8; Bf 4; Tr 2; Cx 1 ( Figure 6 ). Leg II: Ta 1ω, 1Cp, 2ζ, 17 (18); Ti 2φ, 12; Ge 1σ, 9; Tf 5; Bf 4; Tr 2; Cx 1 ( Figure 7 ). Leg III: Ta 1ζ, 19 (16); Ti 1φ, 11 (12); Ge 1σ, 8 (9); Tf 5; Bf 4; Tr 2; Cx 1 ( Figure 8 ).

Measurements are given in Table 1 .

Etymology: Named after its occurrence in Balkan Peninsula.

Remarks: Abrolophus balkanicus sp. nov. 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: A. norvegicus ( Thor, 1900) ; A. gracilentus ( Willmann, 1937) ; A. parvum Schweizer and Bader, 1963 ; A. kazimierae ( Haitlinger, 1986) ; A. wratislaviensis ( Haitlinger, 1986) ; A. viburnicolus Fain and Çobanoğlu, 1998 ; and A. baardi ( Haitlinger, 2004) ( Thor, 1900; Willmann, 1937; Schweizer and Bader, 1963; Haitlinger, 1986, 2004; Fain and Çobanoğlu, 1998). A. gracilentus and A. parvum were described very incompletely and they cannot be compared with the new species. It differs from A. norvegicus in odontus entire vs. odontus very slightly divergent, the shorter L (58–65 vs. 67–88), W (49–59 vs. 58–84), AW (28–36 vs. 42–57), PW (42–49 vs. 62–80), PL (30–36 vs. 44–63), shorter longest dorsal setae (35–43 vs. 50–66), as2 (17–23 vs. 34–60), OD (12–15 vs. 18–33), and Prd (W) (3–4 vs. 7–12); from A. kazimierae in projection on palpfemur bluntly pointed vs. sharply pointed, the shorter AL (33–41 vs. 55–71), PL (30– 36 vs. 45–65), ASE (20–25 vs. 33–50), PSE (38–44 vs. 61– 86), GL (82–92 vs. 99–116), PsFd (32–39 vs. 40–65), OD (12–15 vs. 16–19), and shorter longest dorsal setae (35– 43 vs. 65–77); from A. wratislaviensis in the presence of projection on palpfemur vs. palpfemur without projection, the longer AL (33–41 vs. 20–28), PL (30–36 vs. 22–30), 1a (33–39 vs. 24–33), 2a (26–33 vs. 18–24), 3a (25–36 vs. 18–22), 2b (24–32 vs. 18–23), 3b (31–36 vs. 22–28), Ti III (70–79 vs. 52–70), shorter ASE (20–25 vs. 28–40), PSE (38–44 vs. 53–65), ISD (41–46 vs. 44–54), GL (82–92 vs. 99–108), PaFe (L) (32–37 vs. 39–48), and bs and as2 setulose vs. bs and as2 nude; from A. viburnicolus in entire odontus vs. odontus slightly divergent, palpfemur with projection vs. palpfemur without projection, fV (18–20 vs. 31), the shorter L (58–65 vs. 75), AW (28–36 vs. 42), ISD (41–48 vs. 63), AL (33–41 vs. 52), PL (30–36 vs. 45), shorter longest dorsal setae (35–43 vs. 69), Ti I (55–66 vs. 90) and Ti III (70–79 vs. 85), and longer AP (33–41 vs. 27); and from A. baardi in palpfemur bearing projection vs. palpfemur without projection, the shorter L (58–54 vs. 80–90), ISD (41–48 vs. 58–64), AP (18–24 vs. 26–30), AL (33–41 vs. 54–68), PL (30–36 vs. 54–64), ASE (20–25 vs. 48–54), PSE (38–44 vs. 80–98), GL (82–92 vs. 120–130), 1a (32–39 vs. 46–54), 1b (33–40 vs. 50–58), PsFd (32–39 vs. 46–58), PsGe (L) (11–15 vs. 18–24), Ta I (51–58 vs. 58–78), and Ti III (70–79 vs. 114–130).
