Brueelia (Brueelia) semicingulata sp. nov. urn:lsid:zoobank.org:act: D4F9F87E-6872-4D71-91BB-549F74E7C7A4 Figs 8–14 Differential diagnosis Brueelia semicingulata sp. nov. can be separated from both B. anomala sp. nov. and B. saharae sp. nov. by the following characters: antero-lateral extensions of gonopore does not reach lateral margins of mesosome in B. semicingulata (Fig. 12), but reaches beyond lateral margins in B. anomala (Fig. 5) and B. saharae (Fig. 19); anterior margin of proximal mesosome is flat in B. semicingulata (Fig. 12), but rounded in B. anomala (Fig. 5) and irregular in B. saharae (Fig. 19); patches of dark pigmentation on lateral tergopleurites less extensive in B. semicingulata (Figs 8–9) than in B. anomala (Figs 1–2) and B. saharae (Figs 15–16). Etymology The species epithet is derived from the Latin ‘ semi ’ for ‘half’ and ‘ cingulatus ’ for ‘belted’, referring to the areas of dark pigmentation that reach only half-way across the abdomen. Type material Holotype (ex Emberiza tahapisi arabica) “ ARABIA ” • ♂;locality unknown; Feb.1948; R.Meinertzhagen leg.;17428,17469, NHMUK010693760; NHMUK [marked with black dot on slide]. Paratypes (ex Emberiza tahapisi arabica) “ ARABIA ” • 1 ♂♂, 5 ♀♀; locality unknown; Feb. 1948; R. Meinertzhagen leg.; 17428, 17469, NHMUK010693760; NHMUK. Type host Emberiza tahapisi arabica (Lorenz von Liburnau & Hellmayr, 1902) – cinnamon-breasted bunting. Type locality “Arabia”. Description Both sexes Head slenderly trapezoidal (Fig. 10), lateral margins slightly convex, frons flat to slightly concave. Marginal carina slender, deeply displaced and much widened at osculum. Ventral anterior plate triangular. Head chaetotaxy as in Fig. 10. Preantennal nodi slender, not bulging. Pre-ocular nodi larger than post-ocular nodi. Marginal temporal carinae moderate, irregular. Gular plate lanceolate. Thoracic and abdominal segments as in Figs 8–9. Base pigmentation pale brown; posterior half of marginal carina, margins of antennal sockets, temples, anterior gular plate, proepimera, metepisterna, sternal and subgenital plates, and most of female tergopleurite IX+X medium brown; antero-lateral corners of tergopleurites medium brown as outlined by narrow lines in Figs 8–9. Male Thoracic and abdominal chaetotaxy as in Fig. 8; tergopleurite VII with 1 tps on each side. Basal apodeme slender (Fig. 11), constricted at mid-length. Proximal mesosome square-shaped (Fig. 12). Mesosomal lobes wide, rugose area limited to distal end, 2 pmes sensilla on each side of gonopore. Gonopore with antero-lateral extension not reaching lateral margins of mesosome, anterior margin convex medianly. Penile arms short, not reaching distal margin of mesosome. Parameres somewhat elongated, tapering gently, pst1–2 as in Fig. 13. MEASUREMENTS (n = 2). TL = 1.14–1.17; HL = 0.31–0.32; HW = 0.22–0.23; PRW = 0.14; PTW = 0.20–0.22; AW = 0.29–0.31. Female Thoracic and abdominal chaetotaxy as in Fig. 9. Lateral margins of anterior subgenital plate parallel to slightly convex (Fig. 14), with narrow connection to cross-piece. Vulval margin convergent to blunt median point (Fig. 14), with 3 short, slender vms and 3–5 short, thorn-like vss on each side; 3–4 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. MEASUREMENTS (n = 5). TL = 1.39–1.53; HL = 0.35–0.36; HW = 0.25–0.26; PRW = 0.16–0.17; PTW = 0.23–0.25; AW = 0.33–0.36. Remarks Pterothorax and abdominal segment II are obscured by gut content in all examined specimens, and here illustrated approximately.
