description: Indoceoplanetes (Indoceoplanetes) ephippiformis Gustafsson & Bush, new species
(Figs 57–63)
Type host. Edolisoma montanum montanum (Meyer, 1874) – black-bellied cicadabird.
Type locality. Nakata Range, Wau, Morobe Province, Papua New Guinea.
Diagnosis. Indoceoplanetes (Indoceoplanetes) ephippiformis new species is not morphologically close to any other species in the subgenus, and can be separated from all other known species of In. (Indoceoplanetes) by the following characters: male tergopleurite IV–VI each with 1 ss on each side and tergopleurites VII–VIII with 2 ss on each side (Fig. 57); shape of proximal mesosome (Fig. 61); large, hook-shaped antero-lateral extensions of gonopore (Fig. 61); medianly bulging distal margin of mesosome (Fig. 61); proportionately broad and bulky parameres (Fig. 62).
Description. Both sexes. Head rounded trapezoidal (Fig. 59), lateral margins of preantennal head convex, frons slightly concave. Marginal carina broad, narrowing anterior to dsms, deeply displaced and widened at osculum. Ventral anterior plate rounded triangular, with concave anterior margin. Head chaetotaxy as in Fig. 59. Preantennal nodi wide, bulging. Pre- and post-ocular nodi large, connected dorsally by broad ocular band. Marginal temporal carina slender. Gular plate triangular, lateral margins concave. Thoracic and abdominal segments as in Figs 57–58. Base pigmentation translucent; preantennal and preocular nodi dark brown; area delimited by dotted line in Fig. 59, gular plate, proepimera, and metepisterna medium brown; sternal plates III–VI and subgenital plates pale brown.
Male. Thoracic and abdominal chaetotaxy as in Fig. 57; tergopleurite IV–VI each with 1 ss on each side and tergopleurites VII–VIII with 2 ss on each side. Basal apodeme rounded rectangular (Fig. 60), lateral margins slightly concave. Proximal mesosome with oblique, bluntly rounded antero-lateral extensions (Fig. 61), proximal margin concave. Mesosomal lobes divergent distally. Distal margin of mesosome concave laterally but bulging medianly. Gonopore shaped as in Fig. 61, with large hook-shaped antero-lateral extensions. Dorsal fringe small, tilted slightly distally, without thumb-like process. Chaetotaxy: 2 ventral gpmes microsetae on each side of distal gonopore; 2 lpmes sensilla on each side on mesosomal lobes; 1 dorsal ames microseta on each side distal to dorsal fringe. Parameres and pst1–2 as in Fig. 62. Measurements as in Table 1.
Female. Thoracic and abdominal chaetotaxy as in Fig. 58. Subgenital plate as in Fig. 63, distal end flattened. Vulval margin bulging, median section may be slightly concave, with 1–2 short, slender vms and 1 short, thorn-like vss on each side; 4–7 slender vos on each side of subgenital plate; distal 2–3 vos distal to vss and substantially longer than vms. Measurements as in Table 1.
Etymology. The species epithet is derived from “ ephippion ”, Greek for “saddle”, and the ending “ -formis ” for “having the shape of”, referring to the shape of the proximal mesosome.
Type material. Ex Edolisoma montanum montanum [as Coracina montana]: Holotype ♂, Nakata Ridge, elev. 5000 ft., Wau, Morobe Province, Papua New Guinea, 15 May 1963, P.J.

Paratypes: 2♂, 3♀, same data as holotype (BPBM). 1♀, top of Kassam Pass, elev. 1300 m, Eastern Highlands Province, Papua New Guinea, 25 Aug. 1967, P.H. Colman, BBM-NG-60042 (BPBM).
