Brueelia breueri Balát, 1955: 505.

Type host.

Chloris chloris (Linnaeus, 1758), European greenfinch ( Fringillidae ).

Type locality.

Gabčíkovo, Slovakia.

Description.

Both sexes. Head flat dome-shaped (Fig. 15 ), lateral margins of preantennal area slightly convex, frons broadly concave. Marginal carina narrow, deeply displaced and widened at osculum, median margin undulating. Ventral anterior plate small, shield-shaped. Head chaetotaxy and pigmentation patterns as in Figure 15 ; head sensilla and pts not visible in examined specimens. Preantennal nodi not bulging. Preocular nodi much larger than postocular nodi. Marginal temporal carina moderate in width, with undulating median margin. Gular plate lanceolate, slender. Thoracic and abdominal segments and pigmentation patterns as in Figures 13 , 14 .

Male. Thoracic and abdominal chaetotaxy as in Figure 13 . Basal apodeme with deeply concave lateral margins (Fig. 16 ). Proximal mesosome roughly quadratic, with rounded corners, small (Fig. 17 ). Mesosomal lobes wide, highly convergent distally; rugose area limited to distal margin. Gonopore wider than long. Penile arms not reaching distal margin of mesosome. Parameres slender (Fig. 18 ), distal part elongated; pst1 -2 not visible in examined specimen. Measurements (n = 3, except HW where n = 2): TL = 1.29-1.55; HL = 0.31-0.34; HW = 0.28; PRW = 0.15-0.18; PTW = 0.24-0.30; AW = 0.32-0.37.

Female. Thoracic and abdominal chaetotaxy as in Figure 14 . Subgenital plate rounded pentagonal (Fig. 19 ), with broad connection to cross-piece; pigmentation patterns as in Figure 19 . Vulval margin gently rounded, with 3 short, slender vms and 3 or 4 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 = 6): TL = 1.59-1.95; HL = 0.35-0.38; HW = 0.28-0.32; PRW = 0.18-0.20; PTW = 0.27-0.32; AW = 0.38-0.47.

Type material.

Lectotype ♂ Gabčíkovo, Slovakia, 25 Mar. 1954, F. Balát, 676 (MMBC). Paralectotype. 1♀, Podunajské Biskupice, Slovakia, 20 July 1953, F. Balát, 1118a (MMBC).

Non-types. 1♀, same data as lectotype, 676 (MMBC). 1♂, same data as lectotype, Brit. Mus. 1955-662 (NHML). 1♂, 2♀, same data as paralectotypes,1118b, c (MMBC). 5♀, Neslovice, Czechia, 6 Aug. 1958, F. Balát 1179 (MMBC). 1♂, 1♀, Brno, Czechia, 9. Jan. 1960, F. Balát, 1327 (MMBC). 1♀, same data as paralectotypes, Brit. Mus. 1955-662 (NHML).

Remarks.

Balát (1955) designated a male from Gabčíkovo and a female from Podunajské Biskupice as types; these are therefore syntypes. The word “type” is written in pencil on the slides 676 and 1118a in the MMBC collection. In addition, Balát mentioned seven females and one male from the same two hosts, and one female from Tormafölek (Zala m., Hungary, 4 Apr. 1952, leg. Georg Breuer; not at MMBC) as "other material", which do not comprise type material. Presently, there are 4 slides of B. breueri with a total of two males and four females deposited at MMBC. The other four females, including that from Hungary, are lost. Therefore, to settle the identity of this species, we hereby designate the male on slide 676 as the lectotype of B. breueri . The other syntypes become paralectotypes. Some specimens deposited in the NHML are called “paratypes”, are not type specimens, as they are not referred to as such in the original publication.

Both antennae of the lectotype male are folded underneath the head and seemingly squashed. We have here reversed the dorsal view of the antenna and illustrated it in a more natural position; the antenna in the ventral view is illustrated as in the specimen. However, in both cases the antennae are likely narrower than illustrated here. As both antennae are displaced, the precise location of antennal setae cannot be established, and these have therefore not been illustrated here. Additional material is needed to fully redescribe B. breueri .
