Brueelia fasciata Sychra , new species

( Figs. 1, 3–4, 12–13)

Type host: Amadina fasciata (Gmelin) : cut-throat finch.

Male (n = 5). Head triangular with straight-sided forehead ( Fig. 12). Preantennal region longer than postantennal region. Lateral sides of preantennal region almost straight with marginal carina interrupted in midline. Clavi triangular, diaphanous, longer than the first antennal segment. Pronotum with 1 seta on each posterolateral corner; metanotum with 7 setae (3 long, 4 short) on each posterolateral margin. Metathorax with straight lateral sides ( Fig. 3). All abdominal tergites divided centrally. Tergal setae on each side as follows: tergites II (first apparent tergite)–IV, 0; V, 3–5; VI –VII, 5–7; VIII, 4–5; IX 5–6 ( Fig. 1), terminally with 6 setae. Abdominal sterna with a pair of setae. Male genitalia as in Fig. 4. Endomeral complex contains a pair of broad sacs of rectangular shape, with smooth posterior margin.

Dimensions: PAW, 0.21–0.22; PAL, 0.17–0.18; TW, 0.26–0.28; POL, 0.15–0.18; HL, 0.33–0.36; PW, 0.18–0.19; MW, 0.30–0.33; AWV, 0.43–0.44; TL, 1.29–1.35; GW, 0.075 –0.085 .

Female (n = 2). Similar to male ( Fig. 12) except tergal setae on each side of abdominal segments as follows: II–IV, 0; V, 1; VI –VIII, 1; IX, 4 (2 long, 2 short). Subgenital plate ( Fig. 13) wide, slightly convex posteriorly with medial part almost straight.

Dimensions: PAW, 0.25; PAL, 0.22; TW, 0.30–0.31; POL, 0.16–0.19; HL, 0.38–0.41; PW, 0.20; MW, 0.33–0.34; AWV, 0.50; TL, 1.76–1.84.

Type material. Male holotype, from Amadina fasciata , SENEGAL: Matam (15° 37ʹ N, 13° 20ʹ W), 6 September 2007, Literák, Č apek & Koubek leg. Paratypes: 3 males, 1 female with same data as holotype, deposited in the Moravian Museum, Brno, Czech Republic ( MZM) (O.Sychra-SE55–SE58); 1 male, 1 female, same data as holotype, deposited in the Natural History Museum, London ( NHML) (O.Sychra-SE59–SE60) .

Remarks. A characteristic feature of Brueelia lice from estrildid hosts is a triangular head with a straightsided forehead, and the lateral sides of the marginal carina interrupted in the midline. Brueelia fasciata is morphologically similar to five species from estrildid hosts: B. stenozona ( Kellogg & Chapman, 1902) ; B. eichleri Lakshminarayana, 1969 ; B. astrildae Tendeiro & Mendes, 1994 ; B. lonchurae Tendeiro & Mendes, 1994 and B. amandavae Rékási & Saxena, 2005 . However, B. fasciata can be separated from them by the following combination of features: 1) absence of setae on tergite II–IV of male; 2) male genitalia with broad endomeral complex with smooth posterior margin (male of B. stenozona has endomeral complex strongly serrated and male of B. amandavae has slender endomeral complex; the other species of Brueelia were described on the basis of single females); 3) female subgenital plate wide, slightly convex posteriorly with medial part almost straight (females of other estrildid Brueelia have subgenital plate with conspicuously convex margin medially); 4) broad head with temple width at least 0.30 mm.
