Indoceoplanetes (Indoceoplanetes) fodincana Gustafsson & Bush, new species

( Figs 36–42 )

Type host. Coracina papuensis oriomo Mayr & Rand, 1936 – white-bellied cuckooshrike.

Type locality. Balimo , Western Province, Papua New Guinea .

Other hosts. Coracina papuensis angustifrons (Salvadori, 1876) . Coracina papuensis elegans (Ramsay, 1881) .

Diagnosis. Indoceoplanetes (Indoceoplanetes) fodincana new species is most similar to In. (In.) wandoensis new species and In. (In.) pterophora new species. For comparisons between In. (In.) fodincana and these two species, see above, under their respective diagnoses.

Description. Both sexes. Head rounded trapezoidal ( Fig. 38 ), lateral margins of preantennal head convex, frons straight to slightly concave. Marginal carina broad, narrowing anterior to dsms, deeply displaced and widened at osculum. Ventral anterior plate rounded, with concave anterior margin and sinuous lateral margins. Head chaetotaxy as in Fig. 38 . 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 36–37 . Base pigmentation pale yellow translucent; head nodi, proepimera, and metepisterna dark brown; marginal and anterior section of marginal temporal carinae, margins of antennal sockets, gular plate, sternal plates IV–VI, and subgenital plates medium brown.

Male. Thoracic and abdominal chaetotaxy as in Fig. 36 ; tergopleurite IV with 1 ss on each side, tergopleurite V with 2 ss on each side, tergopleurite VI with 3 sts on each side; sternite III with 2 sts on each side; abdominal segment V with 1 ps on each side. Basal apodeme rounded proximally, with concave lateral margins ( Fig. 39 ). Proximal mesosome with broad antero-lateral extensions ( Fig. 40 ), and anterior margin concave. Mesosomal lobes divergent distally. Distal margin of mesosome concave. Gonopore with antero-lateral extensions as in Fig. 40 . Dorsal fringe not tilted posteriorly and without thumb-like process. Chaetotaxy: 1 ventral gpmes microseta on each side of distal gonopore; 2 lpmes sensilla on each mesosomal lobe, situated inside the rugose area and difficult to see in some specimens; 1 dorsal ames microseta on each side distal to dorsal fringe. Parameres and pst1–2 as in Fig. 41 . Measurements as in Table 1 .

Female. Thoracic and abdominal chaetotaxy as in Fig. 37 . Subgenital plate as in Fig. 42 , with lateral margins concave distally. Vulval margin gently rounded, with 2 short, slender vms and 1–2 short, thorn-like vss on each side; 5–6 slender vos on each side of subgenital plate; distal 2 vos median to vss and substantially longer than vms. Measurements as in Table 1 .

Etymology. The species epithet is derived from “ fodio ”, Latin for “dig or mine”, and “ incanus ”, Latin for “grey”, referring to the grey plumage of the host species.

Type material. Ex Coracina papuensis oriomo : Holotype ♂, Balimo , elev. 30 ft., Western Province, Papua New Guinea, 12 May 1964, H. Clissold, BBM-NG-50186 ( BPBM) . Paratypes: 3♀, same data as holotype ( BPBM) ; 3♀, Oriomo Rover , elev. 20 ft., Western Province, Papua New Guinea, 6 Feb. 1964, H. Clissold, BBM-NG-29409 ( BPBM) .

Additional material examined (non-types): Ex Coracina papuensis angustifrons : 2♂, 1♀, Mt. Lamington, elev. 500 m, vicinity of Amboga Road , Northern District , Papua New Guinea, 4 Jul. 1966, P.J. Shanahan, BBM-NG-25244 ( BPBM); 3♂, 1♀, Wau CK, Morobe Province, Papua New Guinea, 9 Sep. 1962, [H.] Clissold, BM-NG-20557 ( BPBM) .

Ex Coracina papuensis elegans : 3♀, Tabalia , elev. 20 m, Guadalcanal Island, Solomon Islands [as New Guinea], 31 May 1964, P.J. Shanahan, BBM-NG-23917 ( BPBM) .

Remarks. Most of the specimens from C. p. angustifrons are poorly preserved, but tentatively identified as In. (In.) fodincana based on the characters that can be observed. More specimens are needed to confirm that the population living on this host subspecies is conspecific with those living on other host subspecies.
