Diagnosis.
Larva. The following combination of characters distinguishes P. arfak sp. nov. from other species of Papuanatula s. str.: body dorsally with irregular row of long, fine, simple setae along midline; abdominal terga without distinct protuberances; abdominal terga I – VI with hypodermal wide dark brown transverse band close to anterior margin, I – IX with medial narrow, dark brown, longitudinal streak; femur proximally with wedge-shaped blank; abdominal terga with triangular, apically rounded denticles on posterior margin; small scattered scales on abdominal terga oblong, striated, apically denticulate; paracercus with nine segments.
Description.
Larva (Figs 1 View Figure 1 – 5 View Figure 5 ). Body length 4.5–5.7 mm, cerci much longer than body length (~ 1.4 ×).
Cuticular coloration (Figs 1 a – c View Figure 1 , 3 a View Figure 3 ). Head, thorax and abdomen dorsally brown; thorax with indistinct, complex pattern. Femur proximally with wedge-shaped blank, surrounded by grey area, distally yellow-brown to grey-brown; tibia grey; tarsus grey-brown, distally darker. Head, thorax and abdominal segment I ventrally ecru, protuberances of thoracic sterna brown; abdominal segments II – X ventrally brown, laterally paler. Cerci yellow-brown.
Hypodermal coloration (Fig. 1 a View Figure 1 ). Abdominal terga I – VI (VII) with wide dark brown transverse band close to anterior margin, I – IX with narrow dark brown transverse band close to posterior margin and medially narrow dark brown, longitudinal streak.
Head (Figs 1 b View Figure 1 , 3 h View Figure 3 ). Dorsally with irregular row of long, fine, simple setae along midline.
Antenna. Length ~ 1.5 × head length. As typical for subgenus.
Developing turbinate eyes in last instar male larva (Fig. 3 h View Figure 3 ) large, subquadrangular, touching each other in the middle.
Labrum (Fig. 2 a, b View Figure 2 ). Length 0.5 × maximum width, laterally convex. Dorsal, sub-marginal arc with ~ 30 feathered setae.
Right mandible (Fig. 2 c View Figure 2 ). Margin between prostheca and mola straight, with row of minute denticles. Otherwise, as typical for subgenus.
Left mandible (Fig. 2 d View Figure 2 ). Margin between prostheca and mola straight, with row of minute denticles. Otherwise, as typical for subgenus.
Hypopharynx (Fig. 2 f View Figure 2 ). As typical for genus.
Maxilla (Fig. 2 g, h View Figure 2 ). Maxillary palp subequal in length to galea-lacinia; palp segment II slightly longer than segment I. Otherwise, as typical for the genus.
Labium (Fig. 2 e View Figure 2 ). Paraglossa dorsally with two spine-like setae near inner, distolateral margin. Labial palp with segment I subequal in length to segments II and III combined. Segment II with minute distomedial protuberance, dorsally with row of five or six spine-like setae near outer, distolateral margin. Segment III slightly pentagonal, pointed; 0.8 × length of segment II. Otherwise, as typical for the genus.
Thorax. Sterna (Fig. 1 c View Figure 1 ). With small protuberances on sides of prosternum and close to openings of mesothoracic and metathoracic sternal apodemes.
Terga (Fig. 1 b View Figure 1 ) without protuberance; with irregular row of long, fine, simple setae along midline.
Legs (Fig. 3 a – g View Figure 3 ). 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 ~ 4 × maximum width. Claw with one row of 5–8 denticles and one posterior setae. Otherwise, as typical for subgenus.
Abdomen. Terga (Figs 1 b View Figure 1 , 4 a View Figure 4 , 5 a, b View Figure 5 ) with irregular row of long, fine, simple setae along midline. Terga without protuberances, terga I – IV with slight, paired medioposterior elevations. Posterior margin of terga: I smooth, without denticles, II – IX with triangular, partly apically rounded denticles, becoming longer toward end of abdomen. Surface with scattered small, oblong, striated, apically serrate scales.
Tergalii (Fig. 4 e, f View Figure 4 ). Present on terga II – VII. Broad ovoid, tracheation well developed and pigmented; margin smooth, with short, fine, simple setae. Tergalius II nearly reaching end of tergum IV, tergalius IV as long as length of terga V and VI combined, tergalius VII nearly reaching end of tergum IX.
Paraproct (Fig. 4 g – i View Figure 4 ). Posterior margin with prolongation and dense row of minute denticles.
Caudalii (Fig. 4 b – d View Figure 4 ). Cerci apart from basal part with 1–6 swimming setae per segment, increasing toward distal part. Paracercus with nine segments.
Pose of subimaginal gonostyli under larval cuticle (Fig. 2 i View Figure 2 ) as typical for the subgenus.
Subimago. Unknown.
Imago. Unknown.
Egg. Unknown.
