Nemuus imperator Gustafsson & Bush  , new species

( Figs 338–345View FIGURES 338 – 339View FIGURES 340 – 345)

Type host. Artamus maximus Meyer, 1874  —great woodswallow. Type locality. Wanuma, Madang District, Papua New Guinea.

Diagnosis. Nemuus imperator  n. sp. is separated from Ne. hoedhri  n. sp. by the following characters: preantennal area shorter than postantennal area in Ne. imperator  ( Fig. 340View FIGURES 340 – 345), but about as long as postantennal area in Ne. hoedhri  ( Fig. 348View FIGURES 348 – 353); dorsal anterior plate longer than broad in Ne. hoedhri  ( Fig. 340View FIGURES 340 – 345), but about as long as broad, or shorter than broad, in Ne. imperator  ( Fig. 348View FIGURES 348 – 353); male scape more swollen in Ne. imperator  ( Fig. 340View FIGURES 340 – 345) than in Ne. hoedhri  ( Fig. 348View FIGURES 348 – 353); accessory sts present on segment II in both sexes of Ne. hoedhri  ( Figs 346–347View FIGURES 346 – 347) but absent in Ne. imperator  ( Figs 338–339View FIGURES 338 – 339); tps  present on female tergopleurites II –V in Ne. hoedhri  ( Fig. 346View FIGURES 346 – 347), but absent on these tergopleurites in Ne. imperator  ( Fig. 339View FIGURES 338 – 339); indentation of posterior margin of the female subgenital plate reaches farther than mid-length in Ne. hoedhri  ( Fig. 353View FIGURES 348 – 353) but only to about mid-length in Ne. imperator  ( Fig. 345View FIGURES 340 – 345); Ne. hoedhri  with 3–4 vms, 8–10 vss, and 6–8 vos on each side ( Fig. 353View FIGURES 348 – 353), and Ne. imperator  with 4–5 vms, 10–12 vss, and 5–6 vos on each side ( Fig. 345View FIGURES 340 – 345); mesosome with large distal nodi and no rugose area in Ne. imperator  ( Fig. 343View FIGURES 340 – 345), but with slender thickenings and large rugose areas in Ne. hoedhri  ( Fig. 351View FIGURES 348 – 353); parameral heads moderate, folded distally more than medianly, in Ne. hoedhri  ( Fig. 352View FIGURES 348 – 353), but wide, folded medianly in Ne. imperator  ( Fig. 344View FIGURES 340 – 345); distal parameres blunt in Ne. hoedhri  ( Fig. 352View FIGURES 348 – 353) but pointed in Ne. imperator  ( Fig. 344View FIGURES 340 – 345).

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 340View FIGURES 340 – 345. Preantennal area very short, flattened. Frons flat or shallowly concave. Dorsal anterior plate wider than long. Ventral, marginal, and occipital carinae, ventral anterior plate, mandibular framework, and gular plate with medium-brown pigmentation. Head nodi with deep-brown pigmentation. Thoracic and abdominal segments as in genus description and Figs 338–339View FIGURES 338 – 339. Lateral section of tergopleurites, metepisterna, proepimera, meso- and metasterna, sternal plates, subgenital plate, and broad band along vulval margin with light-brown pigmentation, progressively darker posteriorly.

Male. Scape swollen ( Fig. 340View FIGURES 340 – 345). Subgenital plate with distinct lateral indentation at about half-length ( Fig. 338View FIGURES 338 – 339). Abdominal chaetotaxy as in Table 2 and Fig. 338View FIGURES 338 – 339. Basal apodeme notched anteriorly ( Fig. 342View FIGURES 340 – 345). Proximal mesosome broadly flattened, overlapping with basal apodeme ( Fig. 343View FIGURES 340 – 345). Gonopore narrowly open distally. Mesosomal lobes slender, elongated, with distinct nodi in anterior and posterior ends. Posterior nodi large, triangular; anterior nodi rounded; 2 ames microsetae on each side submedianly anterior to gonopore; 2 pmes microsetae on each side on lateral margins of mesosomal lobes just anterior to distal nodi. Parameral heads ( Fig. 344View FIGURES 340 – 345) roughly triangular, folded medianly. Parameral blades long, pointed distally; pst1 as in genus description; pst2 marginal. Measurements ex Artamus maximus  (n = 21 except n = 20 for AW and n = 17 for TL): TL =1.36–1.62 (1.53); HL = 0.36–0.42 (0.40); HW = 0.41–0.49 (0.46); PRW = 0.28–0.34 (0.31); PTW = 0.44–0.54 (0.48); AW = 0.54–0.71 (0.65).

Female. Scape not swollen ( Fig. 341View FIGURES 340 – 345). Abdominal chaetotaxy as in Table 2 and Fig. 339View FIGURES 338 – 339; tps  absent on segments II –V. Posterior margin of subgenital plate narrowly indented medianly to about mid-length ( Fig. 345View FIGURES 340 – 345). Broad band of light brown pigmentation follows vulval margin. Vulval margin gently rounded ( Fig. 345View FIGURES 340 – 345); 4–5 short, slender vms on each side, and 10–12 short, thorn-like vss on each side; 5–6 short, slender vos on each side; distal vos median to vss. Measurements (n = 26): TL = 1.69–2.66 (2.18); HL = 0.43–0.48 (0.45); HW = 0.47–0.55 (0.51); PRW = 0.30–0.35 (0.32); PTW = 0.49–0.57 (0.52); AW = 0.70–0.90 (0.79).

Etymology. The species epithet derived from Latin “ imperator  ” for “emperor”, referring to the large size of this species.
