Diagnosis.

Larva. The following combination of characters distinguishes P. copis 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 protuberances, with long, fine points, oriented dorsoposteriad, on abdominal segment (s) IX (X) vestigial; labial palp segment II without distomedial protuberance; segment III globular; femur with angulate blank in basal part; paracercus vestigial.

Description.

Larva (Figs 7 – 13). Body length 6.0– 6.5 mm, cerci much longer than body length (~ 2 ×).

Cuticular coloration (Figs 7 a, b, 8 a – c). Head, thorax and abdomen dorsally brown to dark brown. Thorax with complex markings. Abdominal segments I – VI (– IX) anteriorly and laterally darker, VII – IX at least laterally darker. Head and thorax ventrally ecru; abdomen ventrally pale yellow-brown, laterally with brown markings. Legs yellow-brown to brown, femur with angulate blank in basal part. Caudalii yellow-brown.

Hypodermal coloration. Abdominal segments I – IX dorsally with transverse band on posterior margins (Fig. 8 a).

Head. Antenna (Fig. 10 e). Length ~ 1.5 × head length. As typical for subgenus. Developing turbinate eyes in last instar male larva (Fig. 10 e) rather narrow, with big distance from each other. Labrum (Fig. 9 a, b). Length 0.4 × maximum width, laterally slightly angulate. Dorsal, sub-marginal arc with> 50 densely articulated, feathered setae (30–35 setae according to Lugo-Ortiz and McCafferty 1999: 65). Right mandible (Fig. 9 d, e). Margin between prostheca and mola smooth, without denticles. Otherwise, as typical for subgenus. Left mandible (Fig. 9 f, g). Margin between prostheca and mola, smooth, without denticles. Subtriangular process often undeveloped. Otherwise, as typical for subgenus. Hypopharynx (Fig. 9 c). As typical for genus. Maxilla (Fig. 10 c, d). Maxillary palp slightly longer than galea-lacinia; palp segment II slender, partly sclerotized, approx. as long as segment I, segment I thicker. Otherwise, as typical for genus. Labium (Fig. 10 a, b). As typical for genus. Paraglossa with two spine-like setae near inner margin. Labial palp with segment I 0.8 × length of segments II and III combined. Segment II without distomedial protuberance, dorsally with row of 2–5 spine-like setae near outer, distolateral margin. Segment III globular, slightly pointed, 0.7 × length of segment II; inner dorsal margin with few feathered setae.

Thorax. Sterna. Protuberances poorly developed. Terga (Figs 7 a, b, 8 a, b, 13 b). Metanotum medially with conspicuous, long protuberance, oriented dorsoposteriad. Immature larva with short, acute, posteromedial protuberance on pro- and mesonotum. Legs (Fig. 11 a – h). Ratio of leg segments: fore leg 0.9: 1.0: 0.3: 0.1, middle leg 0.9: 1.0: 0.3: 0.1 and hind leg 1.1: 1.0: 0.3: 0.1. Femur. Length ~ 3 × maximum width. Claw with one row of seven or eight denticles and one posterior seta.

Abdomen. Terga (Figs 12 a, b, 13 a). Abdominal terga I – VIII medially with conspicuous, long protuberances, with long, fine points, oriented dorsoposteriad, on abdominal segment (s) IX (X) vestigial. Posterior margin of terga I – IX with small, triangular, pointed denticles. Surface with scattered small, conical, apically rounded scales. Tergalii (Fig. 11 i, j) ovoid, tracheation developed; with brown pigmentation in middle area; margins with minute serration and many short, fine, simple setae. Paraproct (Fig. 12 e – g). Posterior margin with prolongation and with row of many minute denticles. Caudalii (Fig. 12 c, d). Cerci without swimming setae; sometimes few vestigial swimming setae or insertions still present. Paracercus vestigial.
