Gustafsson, Daniel R. & Bush, Sarah E., 2022, Chewing lice of the Brueelia-complex (Phthiraptera: Ischnocera) parasitic on members of the Campephagidae (Aves: Passeriformes), with description of a new subgenus and 14 new species, Zootaxa 5165 (1), pp. 1-55 : 29-31

Indoceoplanetes (Capnodella) subarcens Gustafsson & Bush, new species

( Figs 64–65 , 69 , 72 , 77–79 )

Type host. Edolisoma melas melas (Lesson, 1828) – black cicadabird.

Type locality. Vogelkop , West Papua Province, Indonesia .

Diagnosis. Indoceoplanetes (Capnodella) subarcens new species is most similar to In. (Cp.) saucia new species, both sharing the following characters: preantennal head gently rounded (cf. Figs 72–73 ); dorsal preantennal suture extends median to ads (cf. Figs 72–73 ); abdominal segment IV in both sexes with 2 ps on each side (cf. Figs 64–67 ); vulval margin gently rounded (cf. Figs 69–70 ).

These two species can be separated by the following characters: female abdominal segments V–VI with 2 ps on each side in In. (Cp.) saucia ( Fig. 67 ), but with 3 ps on each side in In. (Cp.) subarcens ( Fig. 65 ); proximal mesosome broadly flattened in In. (Cp.) subarcens ( Fig. 78 ), but rounded in In. (Cp.) saucia ( Fig. 81 ); shape of gonopores (cf. Figs 78, 81 ); female subgenital plate broader and more rounded distally in In. (Cp.) saucia ( Fig. 70 ) than in In. (Cp.) subarcens ( Fig. 69 ).

Description. Both sexes. Head flat dome-shaped ( Fig. 72 ), lateral margins of preantennal head convex, frons rounded. Marginal carina broad, narrowing conspicuously near dsms, interrupted submedianly. Dorsal preantennal suture reaching dsms and ads, continuing median to ads, but not completely separating dorsal anterior plate, and not reaching lateral head margins. Dorsal anterior plate broader than long, lateral margins irregular; sinuous thickening in posterior part. Ventral anterior plate diffuse, rounded rectangular. Head chaetotaxy as in Fig. 72 . Preantennal nodi large, elongated, bulging. Pre- and postocular nodi of roughly equal size. Marginal temporal carina slender, of roughly even width. Gular plate with slightly concave lateral margins converging on median point. Thoracic and abdominal segments as in Figs 64–65 .

Male. Thoracic and abdominal chaetotaxy as in Fig. 64 ; segment IV with 2 ps on each side. Basal apodeme roughly rectangular, but expanding markedly in distal section ( Fig. 77 ). Proximal mesosome broadly flattened ( Fig. 78 ). Mesosomal lobes only partially overlapping parameral heads. Gonopore as in Fig. 78 ; distal margin deeply incised medianly, antero-lateral extensions slightly curved. Parameres broad throughout; pst1–2 as in Fig. 79 . Measurements as in Table 1 .

Female. Thoracic and abdominal chaetotaxy as in Fig. 65 ; segment IV with 2 ps on each side; segments V–VI with 3 ps on each side. Subgenital plate pentagonal ( Fig. 69 ). Vulval margin gently rounded, with 1–2 short, slender vms and 3–5 short, thorn-like vss on each side; 5–10 slender vos on each side of subgenital plate; distal 2–4 vos positioned median to vss, and markedly longer than vms. Measurements as in Table 1 .

Etymology. The species epithet is derived from Latin “ sub -” for “almost” and Latin “ arcens ” for “enclosing”, referring to the almost transversally complete dorsal preantennal suture.

Type material. Ex Edolisoma melas melas [as Edolisoma melan ]: Holotype ♂, Vogelkop, West Papua Province [as Netherlands New Guinea], Indonesia, 19 Jan. 1962, L.W. Quate, BBM-NG-793 ( NHML). Paratypes: 3♂, 4♀, same data as holotype ( NHML) .
