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).
