Brueelia rosickyi Balát, 1955: 517.

Type host.

Sylvia nisoria (Bechstein, 1792), barred warbler ( Sylviidae ).

Type locality.

Těšice u Hodonína, Czechia.

Description.

Both sexes. Head slender, rounded triangular (Fig. 57 ), lateral margins of preantennal area convex, frons narrowly concave. Marginal carina slender, deeply displaced at osculum, median margin slightly undulating. Ventral anterior plate not visible. Head chaetotaxy and pigmentation patterns as in Figure 57 . Preantennal nodi not bulging. Pre- and postocular nodi small, of roughly similar size. Marginal temporal carina of moderate width, median margin undulating. Gular plate broadly lanceolate. Thoracic and abdominal segments and pigmentation patterns as in Figures 55 , 56 .

Male. Thoracic and abdominal chaetotaxy as in Figure 55 . Basal apodeme widening distally, with lateral margins slightly concave at mid-point (Fig. 58 ). Proximal mesosome large, trapezoidal with slightly concave lateral margins (Fig. 59 ). Mesosomal lobes slender, converging distally; rugose area extensive along distal margin. Parameres slender, elongated (Fig. 60 ); pst1-2 as in Figure 60 . Measurements (n = 3): TL = 1.28-1.36; HL = 0.33-0.35; HW = 0.22-0.24; PRW = 0.15-0.16; PTW = 0.23-0.24; AW = 0.33-0.35.

Female. Thoracic and abdominal chaetotaxy as in Figure 56 . Subgenital plate pentagonal, with narrow connection to cross-piece (Fig. 61 ). Vulval margin convergent to rounded median point, with 3-5 short, slender vms and 3 or 4 short, thorn-like vss on each side; 2 or 3 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. Measurements (n = 17): TL = 1.57-1.77 (1.66); HL = 0.36-0.38 (0.37); HW = 0.25-0.28 (0.26); PRW = 0.16-0.18 (0.17); PTW = 0.25-0.28 (0.26); AW = 0.36-0.42 (0.39).

Type material.

Lectotype ♂, Těšice u Hodonína, Czechia, 15 May 1953, F. Balát, 1133a (MMBC). Paralectotype. 1♀, same data as lectotype, 1133b (MMBC).

Non-type material. 1♂, 14♀, same data as lectotype, F. Balát, 1133c-q (MMBC). 1♂, 2♀, Járok u Nitry, Slovakia, 17 June 1953, F. Balát, 1070 (MMBC). 1♀, Liteň, Czechia, 19 May 1938, K. Pfleger (MMBC).

Remarks.

Balát (1955) did not designate any holotype, but mentioned a male and a female as “types”; these two specimens comprise the syntype series. The specimens on slides 1133a and 1133b are marked accordingly in handwriting, and the male is here designated the lectotype with the female becoming the paralectotype. All other specimens mentioned by Balát as additional specimens have no type status. Slide 1133d is marked "allotype female" and slides 1133e-n are marked “paratypes”, but this does not seem to be in Balát’s hand. Presently, 20 slides with a total of four males and 18 females are deposited at the MMBC. We have been unable to trace the remaining one male and three females and consider them to be lost.
