Diagnosis.

Larva. The following combination of characters distinguishes P. paracopis sp. nov. from other species of Papuanatula s. str.: body dorsally without row of long, fine, simple setae along midline; metanotum and abdominal terga I – VIII medially with conspicuous, long, hook-like protuberance, bent posteriad, on abdominal segment (s) IX (X) vestigial; labial palp segment II with small, distolateral protuberance; segment III oblong, conical; femur anteriorly with angulate blank in basal 1 / 2; paracercus vestigial.

Description.

Larva (Figs 83 View Figure 83 – 89 View Figure 89 ). Body length ~ 6.8 mm, cerci much longer than body length.

Cuticular coloration (Figs 83 a – c View Figure 83 , 84 a, b View Figure 84 ). Head, thorax and abdomen dorsally brown to dark brown, abdominal segments X and partly IX brighter. Thorax with complex markings. Abdominal segments I – IX anteriorly and laterally darker, segments IV – IX with two dark brown dots in anteromedial area. Head and thorax ventrally ecru, thorax with pale brown to dark brown, paired protuberances near distolateral corners of sterna; abdomen ventrally pale yellow-brown, laterally with brown markings. Legs yellow-brown to brown, femur medially with submarginal brown streak and basally with angulate blank. Caudalii yellow-brown.

Hypodermal coloration (Figs 83 a View Figure 83 , 84 a View Figure 84 ). Abdominal terga I – IX with wide dark brown transverse band close to anterior margin and narrower dark brown transverse band close to posterior margin.

Head. Antenna (Fig. 86 d View Figure 86 ). Length ~ 1.5 × head length. As typical for subgenus. Developing turbinate eyes in last instar male larva (Fig. 86 d View Figure 86 ) rather narrow, with big distance to each other. Labrum (Fig. 85 a, b View Figure 85 ). Length 0.6 × maximum width, laterally convex. Dorsal, sub-marginal arc with> 50 densely articulated, feathered setae. Right mandible (Fig. 85 d, e View Figure 85 ). Margin between prostheca and mola smooth, without denticles. Otherwise, as typical for subgenus. Left mandible (Fig. 85 f – h View Figure 85 ). Margin between prostheca and mola with minute denticles toward subtriangular process. Otherwise, as typical for subgenus. Hypopharynx (Fig. 85 c View Figure 85 ). As typical for genus. Maxilla (Fig. 86 c View Figure 86 ). Maxillary palp slightly longer than galea-lacinia; palp segment II slender, partly sclerotized, approx. 1.2 × as long as segment I, segment I thicker than segment II. Otherwise, as typical for genus. Labium (Fig. 86 a, b View Figure 86 ). As typical for genus. Paraglossa dorsally with two spine-like setae near inner, distolateral margin. Labial palp with segment I 0.8 × length of segments II and III combined. Segment II with very small, rounded, distomedial protuberance, dorsally with row of four or five spine-like setae near outer, distolateral margin. Segment III oblong, pointed, 0.6 × length of segment II; inner dorsal margin with few feathered setae.

Thorax. Sterna. Protuberances poorly developed. Terga (Figs 83 b View Figure 83 , 84 b View Figure 84 , 88 a View Figure 88 , 89 a View Figure 89 ). Mesonotum with small, posteromedial protuberance; metanotum posteromedially with hook-like, pointed protuberance, bent posteriorly. Immature larva with short, acute, posteromedial protuberance on pronotum. Surface of fore protoptera along developing veins and on inner margins with small, triangular, pointed scales. Legs (Fig. 87 a – e View Figure 87 ). Ratio of leg segments: fore leg 0.9: 1.0: 0.3: 0.2, middle leg 1.0: 1.0: 0.3: 0.2 and hind leg 1.1: 1.0: 0.3: 0.2. Femur. Length ~ 3.5 × maximum width. Claw with one row of nine denticles, 1 st denticle longer than other ones, and one posterior seta.

Abdomen. Terga (Figs 83 b View Figure 83 , 84 b View Figure 84 , 88 a – c View Figure 88 , 89 a – e View Figure 89 ). Abdominal terga I – VIII posteromedially with conspicuous, long, hook-like protuberance, bent posteriad, on abdominal segment (s) IX (X) vestigial; Posterior margin of terga: I smooth, without spines; II – IX with small, triangular, pointed denticles, increasing in length toward IX. Surface with scattered small, triangular, pointed scales. Tergalii (Fig. 87 f, g View Figure 87 ). Broad oblique ovoid; tracheation developed, hardly visible due to brown pigmentation in large middle part; margins with minute serration and many short, fine, simple setae. Paraproct (Fig. 88 g View Figure 88 ). Posterior margin with prolongation and with row of many minute denticles. Caudalii (Fig. 88 d – f View Figure 88 ). Cerci without swimming setae; sometimes few rudimentary swimming setae or insertions still present. Paracercus vestigial.
