Sturnidoecus  mon Gustafsson & Bush, new species

( Figs 406–414View FIGURES 406 – 407View FIGURES 408 – 412View FIGURES 413 – 414)

Type host. Euplectes hordeaceus ( Linnaeus, 1758)  —black-winged bishop. Type locality. Lovi , Mole, Northern Region, Ghana. 

Diagnosis. Sturnidoecus  mon n. sp. is the only known species in its group, and is separated from all other Sturnidoecus  by the shape of the male genitalia ( Figs 389View FIGURES 384 – 389, 411–413View FIGURES 408 – 412View FIGURES 413 – 414). Apart from St. mon, the only Sturnidoecus  species-groups with largely flat posterior margins of the mesosome are the St. porphyrogenitus  ( Fig. 391View FIGURES 390 – 395) and St. simpl  ex ( Fig. 394View FIGURES 390 – 395) species-groups, however apart from this superficial similarity, these three species groups are very different in the male genitalia. Sturnidoecus  mon is the only known species in the genus with a clearly defined, subterminal gonopore ( Fig. 410View FIGURES 408 – 412), an irregular, somewhat frayed-looking anterior margin of the proximal mesosome, and paired ventral rectangular flaps of the anterior mesosomal lobes. Females can only be distinguished from other species of Sturnidoecus  by the median bulge of the vulval margin ( Fig. 412View FIGURES 408 – 412).

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 408View FIGURES 408 – 412; as1 absent. Preantennal nodi not broader than marginal carinae, not distinct. Coni slender, reaching just beyond distal margin of scapes. Preocular nodi small, square-shaped. Postocular nodi not distinct; pos located at posterior margin of eye. Gular plate broad, very angular. Thoracic and abdominal segments as in genus description and Figs 406– 407View FIGURES 406 – 407. Posterior margin of pterothorax rounded in both sexes. Sternal plates large, present on segments II –VI in both sexes.

Male. Abdominal chaetotaxy as in Table 11 and Fig. 406View FIGURES 406 – 407. Male genitalia as in genus and species group descriptions and Figs 409–411View FIGURES 408 – 412. Measurements ex Euplectes hordeaceus  (n = 5): TL = 1.14–1.22; HL = 0.38–0.41; HW = 0.37–0.42; PRW = 0.21–0.23; PTW = 0.30–0.36; AW = 0.44–0.47.

Female. Abdominal chaetotaxy as in Table 11 and Fig. 407View FIGURES 406 – 407. Subgenital plate roughly triangular, lateral margins irregular distally ( Fig. 412View FIGURES 408 – 412). Vulval margin bulging distinctly in median section ( Fig. 412View FIGURES 408 – 412), with 3–4 short slender vms on bulging section on each side, and 8–10 thorn-like vss on each side; 5–7 long, slender vos on each side; distal 1–2 vos median to vss. Measurements ex Euplectes hordeaceus  (n = 2): TL = 1.33–1.41; HL = 0.42– 0.44; HW = 0.42–0.43; PRW = 0.23 –0.24; PTW = 0.36–0.38; AW = 0.52–0.59.

Etymology. The species epithet is derived from Japanese “ mon ” for “gate”, as the overall shape of the mesosome and parameres ( Fig. 409View FIGURES 408 – 412) resemble the stylized shape of the Japanese torii gates.

Type material. Ex Euplectes hordeaceus  : Holotype ♂, Lovi , Mole [National Park], Northern Region, Ghana, 26 Aug. 1968, Oxford University Expedition, Brit. Mus. 1969-32 ( NHML)  . Paratypes: 9♂, 4♀, same data as holotype ( NHML)  .
