Papuanatula (Papuanatula) tuber Lugo-Ortiz & McCafferty, 1999.
Diagnosis (larval characters).
Distal part of antenna asymmetrical: each flagellomere with anterior side more convex than posterior side, with brown hypodermal spot near apex of anterior side (Fig. 2 b). Labrum dorsally with submarginal row of long, feathered setae (Fig. 3 b). Each seta consists of a stout stem and long processes on both sides. Mandibles. Both mandibles long, with incisor strongly elongated (in contrast to shortened in Papuafiliola nov.); full-length mandibles present only at the beginning of each instar, often worn at the end of instar. Right mandible (Fig. 3 e): kinetodontium deeply separated from incisor; incisor with three denticles; kinetodontium terminating with three or four denticles, with distal denticle longest. Left mandible (Fig. 3 f): incisor and kinetodontium fused at most of its length; incisor with three denticles; kinetodontium terminating with three or four denticles, with distal denticle longest. Labium: glossa usually approximately as long as half of paraglossa; with several long setae at apex and usually one long seta near middle of ventral side. Labial palp without real distomedian projection on segment II (Fig. 3 c) (in contrast to Papuafiliola subgen. nov.). Legs (Figs 4 a – e, 108 b): Outer side of each femur usually with single regular row of long, hair-like setae bearing numerous fine, short branches on all sides. Anterior side of each tibia usually with regular row of setae similar to that on femur. Anterior side of each tarsus usually with regular row of setae similar to femur and tibia. Posterior side of each tarsus with regular row of short, stout setae and one (rarely two) much longer, thinner, pointed seta distad. Paraproct (Fig. 12 e): posterior margin usually with prolongation. Pose of subimaginal gonostyli under larval cuticle (Fig. 76 b). Subimaginal gonostyli developing under cuticle of last instar male larvae folded in “ Labiobaetis - type ” (Kluge 2004: fig. 29 I): 1 st segment directed laterally, 2 nd and 3 rd segments directed medially, whereby the 2 nd segment is the closest to the posterior margin of the 9 th segment.
Eggs of examined species without regular relief (Fig. 37 d, e).
