description: Teinomordeus entelosetus Gustafsson & Bush, new species
(Figs 75–82)
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. 80).
Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 77. Preantennal nodi long, slender. Pre-ocular nodi prominent, post-ocular nodi absent. Thoracic and abdominal segments as in genus description and Figs 75–76. Sternal plates moderately pigmented, tergopleurites paler.
Male. Preantennal area short (Fig. 77). Scapes approximately twice as long as in female (Fig. 78). Pteronotum with 5–6 mms on each side. Abdominal chaetotaxy as in Table 32 and Fig. 75. Male genitalia as genus description and Figs 79–81. 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. 76) longer than that of males. Antennae as in Fig. 53. Pteronotum with 5 mms on each side. Abdominal chaetotaxy as in Table 2 and Fig. 76; ps present on segment II. Subgenital plate rounded triangular, reaching vulval margin but not flaring into cross-piece (Fig. 82); vague reticulation in at least mid-section. Vulval margin (Fig. 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. 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).

Ex Eurocephalus rueppelli: 2♂, 4♀, Zuai, Ethiopia, 20 Nov. 1960, S. Brelih, 3076–7, 3079–82 (PMSL).
