Diagnosis.

Larva. The following combination of characters distinguishes P. cyclopomontana sp. nov. from other species of Papuanatula s. str.: body dorsally with irregular row of long, fine, simple setae along midline; abdominal terga without protuberances; paraglossa with three straight setal rows (not bent at apex of paraglossa); femur basally with wedge-shaped blank and less contrasting blank on distal ¹ ⁄ 3; tergalii with extensive, brown pigmentation; paracercus with 6–8 segments; abdominal terga II – IX with various denticles, from long and pointed to short and blunt.

Description.

Larva (Figs 33 – 35). Cuticular coloration. Head, pronotum, mesonotum and metanotum brownish, with darker and paler areas; fore protoptera nearly uniformly brown (Fig. 32 c, d). Thoracic pleura brownish, sterna mostly colorless. Cuticle of femur mostly brownish, with clearly outlined wedge-shape blank on proximal ¹ ⁄ 3 and less contrasting blank on distal ¹ ⁄ 3; apex of femur bordered with darker brown (Fig. 32 e – g). Tibia and tarsus mostly brownish (Fig. 32 e – g). Abdominal terga either mostly brownish, or with brown anterior margin and paler remainder part; terga V and VI paler than others (Fig. 32 a). Sterna mostly colorless. Cerci uniformly pale brownish.

Hypodermal coloration. Judging by hypodermal coloration of male imago and female subimagines, legs without hypodermal markings; each abdominal tergum I – IX with dark brown transverse band close to posterior margin (Fig. 36 b, c, g). Tissues surrounding tracheae of tergalii (main trachea and its branches) with extensive brown pigmentation (Fig. 32 a).

Head. Dorsally with irregular row of long, fine, simple setae along midline. Antenna (Fig. 32 d). Length ~ 1.5 × head length. As typical for subgenus. Developing turbinate eyes in last instar male larva (Fig. 32 d) with facets equally developed on middle and peripheral areas. Labrum (Fig. 33 a) widened distally; long, feathered setae on dorsal surface numerous and forming integral, regular transverse row. Right mandible. As typical for subgenus. Left mandible. As typical for subgenus. Hypopharynx (Fig. 33 b). As typical for genus. Maxilla (Fig. 33 c). Maxillary palp shorter than galea-lacinia. Otherwise, as typical for genus. Labium (Fig. 33 d). Paraglossae with proximal 1 / 2 nearly parallel-sided; three apical setal rows straight (not bent at apex of paraglossa). Glossa as long as half of paraglossa, with finger-like (distal) portion as long as triangular (proximal) portion. Labial palp without distomedial projection on segment II; segment III with median margin longer than lateral margin.

Thorax. Sterna. With small protuberances on sides of prosternum and close to openings of mesothoracic and metathoracic sternal apodemes (as Fig. 108 a). Terga without protuberances. Long, fine, soft, colorless setae irregularly situated along midline of all terga (as in Fig. 65 b). Metanotum without hind protoptera or their vestiges. Legs (Figs 32 e – g, 34 c – e). Fore femur widened in proximal part; hind tibia shorter than others. Femur. Outer side of each femur with single regular row of long, hair-like setae bearing numerous fine, short branches on all sides (as in Figs 41 g, 68 b). Tibia. Patella-tibial suture present on all legs, terminated near middle of inner margin of tibia. Tibia-tarsal condylus turned to anterior side. Anterior side of each tibia with regular row of setae similar to that on femur. Tarsus. Anterior side of each tarsus with regular row of similar, but smaller (shorter and narrower) setae. Posterior side of each tarsus with regular row of short, stout, oval setae (looking pointed in profile) and one much longer, thinner, pointed seta distad of them. Claw with row of 5–8 short denticles and one somewhat larger denticle distad of them; long, arched, posterior seta.

Abdomen. Terga (Figs 32 a, 35 a, b). Long, fine, soft, colorless setae irregularly situated along midline of all abdominal terga (as in Fig. 65 b). Abdominal terga without dorsal unpaired or paired protuberances, only with slightly expressed unpaired, median elevations. Abdominal terga with small, roundish scales with small sockets and radial striation (visible in dry condition, but not in Canada balsam). Posterior margins of abdominal terga II – IX with various denticles, from long and pointed to short and blunt, more numerous and long on middle terga, few and short on terga II and IX. Posterior margin of tergum X with smaller, blunt denticles. Tergalii (Fig. 32 a, h) II – VII subequal, oval. Each tergalius with costal and anal ribs narrow, smooth, present on proximal 1 / 2 of tergalius only. Paraproct (Fig. 35 c) with regular row of small, pointed, equal denticles on median margin, without posterior prolongation. Caudalii (Fig. 34 a, b) without swimming setae; vestiges of swimming setae present on distal part of cerci. Paracercus short, consisting of ~ 6–8 segments.

Pose of subimaginal gonostyli under larval cuticle. Unknown.

Subimago. Cuticular coloration. Pronotum and prosternum partly brown (as in Fig. 60 f). Mesonotum pale brown with medioparapsidal suture colorless, other sutures darker brown (Fig. 36 f). Meso- and metathoracic pleura and sterna with colorless, pale brownish and dark brown areas (Fig. 36 e). Cuticle of wings colorless, with microtrichiae brownish. Legs nearly colorless, with pale brown bordering on femur and base of tibia (Fig. 36 d). Abdomen diffusely colored with very pale brownish in distal part.

Hypodermal coloration. As in imago.

Texture. On all legs of both sexes, each tarsomere covered mostly with blunt microlepides, with pointed microlepides near apex (as in Fig. 70 i).

Imago. Imago, male. Head pale ochre. Antennae ochre. Turbinate eyes yellow, widened apically. Thorax ochre, equally pale dorsally, laterally, and ventrally. Fore wing with membrane colorless, veins ochre. Pterostigma with three or four incomplete, oblique cross veins. Legs ochre (Fig. 36 b, c). Abdominal terga mostly ochre, terga II – IV with median part pale brown; each tergum I – IX with darker brown transverse band close to posterior margin; sterna ochre (Fig. 36 g).

Genitalia (Fig. 37). Sterno-styligeral muscle absent. Each unistyliger nearly equally wide at base and at apex, with median margin concave. At lateral side of gonostylus, its 1 st segment roundly-convex and separated from 2 nd segment by concavity; at median side of gonostylus, 1 st segment gradually turns to 2 nd segment. 2 nd segment equally wide all over its length. Third (terminal) segment of gonostylus nearly as wide as 2 nd, with length slightly exceeding width. Penial bridge without projection between unistyligers. Gonovectes dark brown. Each gonovectis parabolic, with lateral (basal) and median (apical) portions equally long, apex bent medially.

Imago, female. Head and thorax dorsally ochre-brownish. Abdomen mostly ochre, terga and sterna with brownish markings, each tergum I – IX with dark brown transverse band close to posterior margin (Fig. 36 h, i). Coloration of legs, wings, and cerci as in male.

Egg (Fig. 37 b). Irregularly oval. Chorion without regular relief.

Dimension.

Fore wing length (and approximate body length) of male and female 3.5 mm.
