Teinomordeus entelosetus Gustafsson & Bush  , new species

( Figs 75–82View FIGURES 75 – 76View FIGURES 77 – 82)

Type host. Eurocephalus rueppelli Bonaparte, 1853  —northern white-crowned shrike. Type locality. “ Somaliland ”, Somalia. 

Diagnosis. Teinomordeus entelosetus  n. sp. is superficially similar to some Brueelia  s. str., particularly Br. nebulosa  and species from Turdoides Cretzschmar, 1826  , which also have abdominal setae in more anterior segments. However, Te. entelosetus  in the only known species in the Brueelia  -complex which has ps on female abdominal segment II, and females are separated from all Brueelia  s. str. on the lack of a cross-piece. Male Te. entelosetus  are separated from all Brueelia  s. str. by the presence of s3 and the shape of the mesomeral lobes and gonopore ( Fig. 80View FIGURES 77 – 82).

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 77View FIGURES 77 – 82. Preantennal nodi long, slender. Pre-ocular nodi prominent, post-ocular nodi absent. Thoracic and abdominal segments as in genus description and Figs 75–76View FIGURES 75 – 76. Sternal plates moderately pigmented, tergopleurites paler.

Male. Preantennal area short ( Fig. 77View FIGURES 77 – 82). Scapes approximately twice as long as in female ( Fig. 78View FIGURES 77 – 82). Pteronotum with 5–6 mms on each side. Abdominal chaetotaxy as in Table 32 and Fig. 75View FIGURES 75 – 76. Male genitalia as genus description and Figs 79–81View FIGURES 77 – 82. Rugose area of mesosomal lobes restricted to lateral and distal margins. Parameres more or less translucent distally; pst1 sensillus, submarginal near distal tip; pst2 seta, lateral near distal tip. Measurements ex Eurocephalus rueppelli  (n = 11, except TL = 10): TL = 0.99–1.15; HL = 0.28–0.32; HW = 0.27–0.31; PRW = 0.17–0.20; PTW = 0.26–0.32; AW = 0.38–0.43.

Female. Preantennal area of females ( Fig. 76View FIGURES 75 – 76) longer than that of males. Antennae as in Fig. 53View FIGURES 51 – 55. Pteronotum with 5 mms on each side. Abdominal chaetotaxy as in Table 2 and Fig. 76View FIGURES 75 – 76; ps present on segment II. Subgenital plate rounded triangular, reaching vulval margin but not flaring into cross-piece ( Fig. 82View FIGURES 77 – 82); vague reticulation in at least mid-section. Vulval margin ( Fig. 82View FIGURES 77 – 82) gently rounded, with 3–5 slender vms on each side, 5–6 thorn-like vss on each side; 5–6 vos on each side, the 1–2 distal vos median to vss. Measurements ex Eurocephalus rueppelli  (n = 24): TL = 1.20–1.45 (1.35); HL = 0.32–0.35 (0.34); HW = 0.28–0.32 (0.30); PRW = 0.16–0.20 (0.18); PTW = 0.27–0.32 (0.30); AW = 0.39–0.51 (0.44).

Etymology. The species epithet is formed by Greek “ entēles ” for “complete” and Latin “ seta ” for “bristle”. This refers to the fact that the females have pleural setae on all segments, that is, the “complete set” ( Fig. 76View FIGURES 75 – 76).

Type material. Ex Eurocephalus rueppelli  [as Eurocephalus angutimiens rueppelli  or Eurocephalus angutimiens erlangeri  ]: Holotype ♂, “Somaliland”, Somalia, Feb. 1949, R. Meinertzhagen, 18680 (NHML). Paratypes: 1♂, 16♀, same data as holotype, 18680–1, 18690–1 (NHML); 9♂, 5♀, Somaliland, Somalia, Jan. 1949, R. Meinertzhagen, 18145 (NHML).
