Indoceoplanetes (Indoceoplanetes) saburrata Gustafsson & Bush, new species

( Figs 8–14 )

Type host. Coracina lineata ombriosa (Rothschild & Hartert, 1905) – barred cuckooshrike.

Type locality. Pepele , Kolombangara Island, Solomon Islands .

Diagnosis. Indoceoplanetes (Indoceoplanetes) saburrata new species is most similar to In. (In.) microgenitalis new species. To distinguish between these two species, see In. (In.) microgenitalis , above.

Description. Both sexes. Head rounded trapezoidal ( Fig. 10 ), lateral margins of preantennal head slightly convex, frons slightly concave. Marginal carina broad, narrowing gradually anteriorly, deeply displaced and widened at osculum.Ventral anterior plate small, crescent-shaped. Head chaetotaxy as in Fig. 10 . Preantennal nodi large, bulging. Pre- and post-ocular nodi large, connected dorsally by broad ocular band. Marginal temporal carina slender. Gular plate triangular. Thoracic and abdominal segments as in Figs 8–9 . Base pigmentation translucent; preocular and preantennal nodi dark brown; mandibular framework, margins of antennal sockets, ocular band, postocular nodi, gular plate, proepimera, metepisterna, sternal plates IV–VI and subgenital plates medium brown; meso- and metasternal plates and sternal plates II–III pale brown.

Male. Thoracic and abdominal chaetotaxy as in Fig. 8 ; tergopleurites II–V with 1 ss on each side; tergopleurites VI–VII with 2 ss on each side; segment VI with 2 ps on each side. Basal apodeme rounded rectangular, lateral margins slightly concave ( Fig. 11 ). Proximal mesosome small, rounded, without lateral bulges or extensions ( Fig. 12 ), anterior margin convex. Mesosomal lobes more or less parallel. Distal margin of mesosome flat. Gonopore with antero-lateral extensions rounded. Dorsal fringe tilted posteriorly, without anterior thumb-like process. Chaetotaxy: 2–3 ventral gpmes on each side of distal gonopore; 2 lpmes sensilla on each side on mesosomal lobes; 1–2 dorsal ames on each side distal to dorsal fringe. Parameres and pst1–2 as in Fig. 13 . Measurements as in Table 1 .

Female. Thoracic and abdominal chaetotaxy as in Fig. 9 ; segment VI with 2 ps on each side. Subgenital plate as in Fig. 14 ; distal margin broadly flattened. Vulval margin gently rounded to somewhat flattened medianly, with 2–3 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 on each side distal to vss and near vms, but substantially longer than vms. Measurements as in Table 1 .

Etymology. The species epithet is derived from Latin “ saburro ” for “I ballast; I fill”, with the arbitrary ending “ -ata ”. This is reference to the bulky-looking male genitalia and the distally broad female subgenital plate.
