Type host.

Turdus viscivorus Linnaeus, 1758, mistle thrush ( Turdidae ).

Type locality.

Zabljak, Montenegro.

Description.

Both sexes. Head flat dome-shaped (Fig. 71 ), lateral margins of preantennal area convex, frons flat to slightly concave. Marginal carina moderate in width, median margin slightly undulating, deeply displaced and widened at osculum. Ventral anterior plate small, shield-shaped with concave anterior margin. Head chaetotaxy and pigmentation patterns as in Figure 71 ; pigmentation very uniform, and difference between different areas slight. Preantennal nodi slightly bulging. Pre- and postocular nodi large. Marginal temporal carina wide, with undulating median margin. Gular plate broad, with concave lateral margins. Thoracic and abdominal segments as in Figures 69 and 70 . Thoracic and abdominal pigmentation more or less uniform, and not denoted in Figures 69 , 70 .

Male. Thoracic and abdominal chaetotaxy as in Figure 69 ; aps on tergopleurites V-VI absent in some specimens, and only present on one side of tergopleurite VI in holotype. Basal apodeme with shallowly concave lateral margins (Fig. 72 ). Proximal mesosome as in Figure 73 . Mesosomal lobes wide, converging distally, with extensive rugose area in distal end. Gonopore large, crescent-shaped. Parameres stout, elongated distally (Fig. 74 ); pst1-s as in Figure 74 . Measurements (n = 12): TL = 1.47-1.64 (1.56); HL = 0.33-0.37 (0.35); HW = 0.28-0.32 (0.30); PRW = 0.19-0.22 (0.21); PTW = 0.28-0.31 (0.30); AW = 0.37-0.44 (0.41).

Female. Thoracic and abdominal chaetotaxy as in Figure 70 . Subgenital plate rounded pentagonal (Fig. 75 ), with connection to cross-piece moderate in width. Vulval margin gently rounded to flattened medianly, with 4 or 5 short, slender vms and 2 or 3 short, thorn-like vss on each side; 3 or 4 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. Measurements (n = 15): TL = 1.53-1.93 (1.73); HL = 0.35-0.41 (0.38); HW = 0.28-0.35 (0.32); PRW = 0.20-0.24 (0.22); PTW = 0.28-0.35 (0.32); AW = 0.40-0.51 (0.46).

Type material.

Holotype ♂, Žabljak, Montenegro, 3 July 1958, S. Brelih (6342), F.B. 1523. Paratypes. 1♀ same collection data as holotype, S. Brelih (6344), F.B. 1524. 3♂, 1♀ Brno - Obora, Czechia, 15 Jun. 1954, F. Balát, 1416, 1417a, b, 1419.

Non-types examined. Ex Turdus viscivorus viscivorus : 2♂, 2♀, Crno Jez, Durmitor, Montenegro, 8 July 1958, S. Brelih, 333, 1990, 1992-1993 (PMSL); 6♂, 10♀, Crno Jez, Durmitor, Montenegro, 3 July 1958, S. Brelih, 428-429, 628-629, 1997-1998, 6338-6339, 6341, 6343, 6345-6347, 6350-6352 (PMSL); 1♀, Crna Gora, Zabljak, Montenegro, 1 Mar. 1958, S. Brelih (NHML).

Remarks.

Balát (1981) explicitly designated the male on slide 1523 ( Brelih’s collection number 6342) as the holotype, and this is confirmed by the handwritten note on the slide label. Another female from the same host specimen (slide no. 1524; Brelih’s collection number 6344), and 20 males, 26 females, and 6 nymphs were designated as paratypes. Presently, six slides with the holotype and five paratypes are at the MMBC. All other specimens are missing from the MMBC, and must be regarded as lost.
