Indoceoplanetes (Indoceoplanetes) pterophora Gustafsson & Bush, new species

( Figs 15–21 )

Type host. Coracina macei nipalensis (Hodgson, 1836) – large cuckooshrike.

Type locality. Nepal .

Diagnosis. Indoceoplanetes (Indoceoplanetes) pterophora new species belongs to a species group with In. (In.) wandoensis new species and In. (In.) fodincana new species. This group is characterised by having the following combination of characters: similar proximal mesosomes ( Figs 19 , 33 , 40 ), mesosomal lobes as in Figs 19 , 33 , 40 ), and 2 sts on each side on male sternite IV ( Figs 15 , 29 , 36 ). Indoceoplanetes (Indoceoplanetes) pterophora can be separated from the other two members of this group by the following characters: male abdominal segment V with 2 ps on each side in In. (In.) pterophora ( Fig. 15 ), but with 1 ps on each side in In. (In.) wandoensis ( Fig. 29 ) and In. (In.) fodincana ( Fig. 36 ); proximal mesosome longer and narrower in In. (In.) pterophora ( Fig. 19 ) than in In. (In.) wandoensis ( Fig. 33 ) and In. (In.) fodincana ( Fig. 40 ).

However, In. (In.) pterophora can be separated from In. (In.) wandoensis by the following characters: head proportionately broader in In. (In.) pterophora ( Fig. 17 ) than in In. (In.) fodincana ( Fig. 31 ); female subgenital plate more flattened distally and vulval margin with median concavity in In. (In.) pterophora ( Fig. 21 ), but rounded distally and with vulval margin concave in In. (In.) wandoensis ( Fig. 35 ); male tergopleurites V–VI with 2 ss on each side in In. (In.) pterophora ( Fig. 15 ), but with 3 ss on each side in In. (In.) wandoensis ( Fig. 29 ); female sternite III with 1 sts on each side in In. (In.) pterophora ( Fig. 16 ), but with 2 sts on each side in In. (In.) wandoensis ( Fig. 30 ).

Furthermore, In. (In.) pterophora can be separated from In. (In.) fodincana by the following characters: female subgenital plate and vulval margin of different shapes (cf. Figs 21 , 42 ); male sternite III with 1 sts on each side in In. (In.) pterophora ( Fig. 15 ), but with 2 sts on each side in In. (In.) fodincana ( Fig. 36 ); male tergopleurites IV and VI each with 2 ss on each side in In. (In.) pterophora ( Fig. 15 ), but male tergopleurite IV with 1 ss on each side and tergopleurite VI with 3 sts on each side in In. (In.) fodincana ( Fig. 36 ).

Description. Both sexes. Head flat dome-shaped ( Fig. 17 ), in some female specimens, more rounded trapezoidal, lateral margins of preantennal area slightly convex, frons rounded to slightly flattened. Marginal carina slender, deeply displaced and widened at osculum. Ventral anterior plate roughly crescent-shaped. Head chaetotaxy as in Fig. 17 . Preantennal nodi slender, bulging. Pre- and post-ocular nodi large, connected dorsally by broad ocular band. Marginal temporal carina slender. Gular plate with convex lateral sides converging to median point. Thoracic and abdominal segments as in Figs 15–16 . Base pigmentation translucent; all specimens were stained red prior to mounting, so true pigmentation is unknown; head nodi, ocular band, gular plate, proepimera, metepisterna, sternal plates IV–VI and subgenital plate dark.

Male. Thoracic and abdominal chaetotaxy as in Fig. 15 ; sternite III with 1 sts on each side; abdominal segment V with 2 ps on each side; tergopleurites IV–VI with 2 ss on each side. Basal apodeme rounded rectangular, lateral margins slightly concave or straight ( Fig. 18 ). Proximal mesosome narrow, with antero-lateral extensions as in Fig. 19 , anterior margin concave. Mesosomal lobes slightly divergent distally. Distal margin of mesosome deeply concave. Gonopore with antero-lateral extensions short and blunt. Dorsal fringe distinctly tilted posteriorly, without thumb-like process. Chaetotaxy: 2 ventral gpmes microsetae on each side of distal gonopore; 2 ventral lpmes sensilla on each side on mesosomal lobes; 1 dorsal ames microseta on each side anterior to dorsal fringes. Parameres and pst1–2 as in Fig. 20 . Measurements as in Table 1 .

Female. Thoracic and abdominal chaetotaxy as in Fig. 16 ; sternite III with 1 sts on each side. Subgenital plate trapezoidal, with irregularly undulating lateral margins in distal section ( Fig. 21 ). Vulval margin slightly concave medianly, with 2–3 short, slender vms and 1–2 short, thorn-like vss on each side; 5–7 slender vos on each side of subgenital plate; distal 2 vos distal to vss and near vms, but substantially longer that vms. Measurements as in Table 1 .

Etymology. The species epithet is derived from Greek “ ptero ” for “wing” and “ phora ” for “bearer”, referring to the wing-shaped median ends of the mesosomal lobes.

Type material. Ex Coracina macei nipalensis : Holotype ♂, Nepal, Mar. 1937, R . Meinertzhagen, 9408 ( NHML). Paratypes: 14♀, same data as holotype ( NHML) .

Remarks. The single male examined has a distorted thorax; therefore, the thoracic segments are illustrated approximately.
