Diagnosis.

Larva. The following combination of characters distinguishes P. lenos from other species of Papuanatula s. str.: body dorsally without row of long, fine, simple setae along midline; body dorsally without protuberances; thorax ventrally without protuberances; pronotum dorsally with large, medial, dark brown marking at anterior margin, and fine, dark brown band along posterior margin; mesothorax with dark brown band along anterior margin; femur anteriorly with large, oblong, red brown to dark brown marking in basal 1 / 2, and pale red brown to dark brown marking in mediodistal area; paracercus with 6–8 segments; paraproct without posterior prolongation.

Description.

Larva (Figs 90 View Figure 90 – 96 View Figure 96 ). Body length 4.0– 5.5 mm, cerci much longer than body length.

Cuticular coloration (Figs 90 a – c View Figure 90 , 91 a View Figure 91 ). Head and thorax dorsally yellow-brown to grey-brown; Abdomen dorsally yellow-brown to dark brown; segments II – IV entirely dark brown, or segment IV with dark brown, crown-like marking; segments I – IX with oblique, dark brown to blackish lateral markings. Head and thorax ventrally ecru, abdomen ventrally pale yellow-brown. Legs yellow-brown to brown; Caudalii yellow-brown.

Hypodermal coloration (Figs 90 a – c View Figure 90 , 91 a View Figure 91 ). Pronotum with large, dark brown marking medially at anterior margin and fine, dark brown band along posterior margin; mesothorax with narrow, dark brown band along anterior margin. Abdominal terga I – IX with wide dark brown transverse band close to anterior margin and narrower dark brown transverse band close to posterior margin. Femur anteriorly with large, oblong, red brown to dark brown marking in basal 1 / 2 (somewhat variable in shape), and pale red brown to dark brown marking in mediodistal area; posteriorly with two red-brown to dark brown streaks close to dorsal margin.

Head. Antenna (Fig. 90 a, c View Figure 90 ). Length ~ 2 × head length. As typical for subgenus. Developing turbinate eyes in last instar male larva (Fig. 93 e View Figure 93 ) large, subquadrangular, nearly touching each other in the middle. Labrum (Figs 92 a, b View Figure 92 , 96 f View Figure 96 ). Length 0.5 × maximum width, laterally convex. Dorsal, sub-marginal arc with 15–17 feathered setae. Right mandible (Fig. 92 d, e View Figure 92 ). Margin between prostheca and mola smooth. Otherwise, as typical for subgenus. Left mandible (Fig. 92 f, g View Figure 92 ). Margin between prostheca and mola smooth, with several spines close to subtriangular process. Otherwise, as typical for subgenus. Hypopharynx (Fig. 92 c View Figure 92 ). As typical for genus. Maxilla (Fig. 93 c, d View Figure 93 ). Maxillary palp slightly longer than galea-lacinia; palp segment II slightly shorter than segment I. Otherwise, as typical for genus. Labium (Fig. 93 a, b View Figure 93 ). As typical for genus. Paraglossa with one spine-like seta on inner, distolateral margin. Labial palp with segment I subequal in length to segments II and III combined. Segment II without distomedial protuberance, dorsally with row of four spine-like setae near outer, distolateral margin. Segment III slightly bulbous, pointed, 0.8 × length of segment II; inner dorsal margin with few feathered setae.

Thorax. Sterna without protuberances. Terga without protuberances. Legs (Fig. 94 a – h View Figure 94 ). Ratio of leg segments: fore leg 0.9: 1.0: 0.3: 0.1, middle leg 1.0: 1.0: 0.3: 0.1 and hind leg 1.1: 1.0: 0.3: 0.1. Femur. Length ~ 2.6 × maximum width. Many medium, pointed, spine-like setae along ventral margin. Claw with one row of 5–7 denticles, distalmost denticle with distance to other denticles; one posterior seta.

Abdomen. Terga (Figs 95 a – c View Figure 95 , 96 a – e View Figure 96 ). Abdominal terga without protuberances. Posterior margin of terga: I – III smooth, without denticles; IV – IX with triangular, pointed denticles. Surface with scattered small, trapezoid, striated, apically serrate scales. Tergalii (Fig. 93 f, g View Figure 93 ). Ovoid, tracheation rather poorly developed; costal margin with minute serration and short, fine, simple setae; anal margin smooth, with short, fine, simple setae. Paraproct (Fig. 95 f View Figure 95 ). Posterior margin without prolongation, smooth, without denticles. Caudalii (Fig. 95 d, e View Figure 95 ). Cerci without swimming setae; sometimes one or two insertions still present. Paracercus with 6–8 segments.

Pose of subimaginal gonostyli under larval cuticle (Fig. 94 i View Figure 94 ). As typical for subgenus. Segment III conical.
