description: Papuanecta inelryjelnor Tinerella, sp. nov.   
(Figs. 1c–d, 4–7)  
 Diagnosis: Similar in habitus to other Papuanecta; however, readily distinguished by the combination of characters given in the key. Females distinguished by size, ground color, and the combination of the prothoracic lobe (Fig. 5a) and metaxyphus (Fig. 5b).   
 Size: (Table 3). Macropterous form. 1.87–1.98. Brachypterous form unknown.   
L= length, LP= length of pronotum, W= body width, WH= width of head, S= synthlipsis, WE= width of eye, WP= width of pronotum, L:W= ratio body length to width, S:E= ratio of synthlipsis to eye width, OcI= ocular index.  
 Derivation of specific epithet: A phonetic spelling of an anagram created from the combination of lionel and jerry lynn, honoring my parents, Mr. and Mrs. Lionel and Jerry Lynn Tinerella, for their generous support and encouragement.

 Description: Based on macropterous form. Measurements. Length: male 1.89–1.98; female 1.87–1.94; Width: male 0.86–0.88; female 0.84–0.88; Width of head: male 0.66–0.68; female 0.67–0.69; Synthlipsis: male 0.27–0.29; female 0.27–0.28; Width of eye: male 0.21–0.22; female 0.21–0.22; Width of pronotum: male 0.71–0.73; female 0.72–0.73; Length of pronotum: male 0.27–0.29; female 0.28–31.   
 Color. Ground color dark brown (Figs. 1c–d). Head pale yellow, eyes dark brown. Clypeus lighter brown. Labium dark brown to black. Genal regions same color as vertex. Antennae brownish, slightly darker than head. Pronotum darker brown, with narrow pale band along apical margin. Clavus with basal diagonal area reddish-ochre colored, apical portion darker brown, as in corium and membrane. Claval-corial commisure with narrow, pale band spanning entire length. Corium solid brown basally, with faint reddish longitudinal markings in apical portion, markings consisting of narrow, broken, darker bands. Scutellum dark brown, paler along basal margin. Prenodal embolar area broad, infuscated with very short pruinose area basally. Postnodal embolar area shallow, pale with lateral darkened areas. Left membrane in both sexes subhyaline, darker brown, inner margin paler, right membrane coriaceous, brown. Venter black, legs same color as head, natatorial setae same color as leg.   
 Structural characteristics. Ratio of body length/width: males 2.23; females 2.23. Head narrower than pronotum, interocular space greater than width of eye, synthlipsis 1.3 times as wide as posterior width of eye. Ocular index: males 1.45; females 1.37. General facies of head (vertex frons, labium) reduced, very short. Antennae densely pilose, segments one and two very short, segment three longer, subparallel-sided, with upper angle rounded and lower angle nearly straight. Pronotum very large, convex, widest at middle, lateral margins truncate, about 2.5 times as wide as long (W/L males 0.72/0.28; females 0.79/0.29). Prothoracic lobe compact, setose, anterior margin acuminate, posterior margin subquadrate, broadly rounded (Fig. 5a). Hemelytra with fine reticulate microsculpturing. Nodal furrow marked by a diagonal suture not contacting wing margin. Prenodal embolar area well developed, wide, postnodal embolar area shallow, very short. Short, minute setae evenly distributed over clavus, corium, and right membrane. Metathoracic wings well developed, reaching apices of hemelytra. Lateral spines and setae on abdominal segments IV–VIII: IV: one long, stout spine, one short, thin seta; V: one long, stout spine, two short, thin setae; VI: two short, stout spines, one long, stout spine; VII: two short, stout spines, three long, stout spines; VIII: two short, stout spines, two long thin setae. Metaxyphus of both sexes short, triangular, setae absent (Fig. 5b).   
Male foreleg (Fig. 5c): femur with two short, stout spines in basal third near ventral surface. Tibia with one long, thin seta dorsally towards anterior portion. Pala with two thin setae dorsally, palmar area with about seven setae in dorsal row and 12–14 setae in lower row, lower row setae more pronounced than those of dorsal row. Apex of pala with single thickened seta. Palar claw (Fig. 5d) narrow, tapered proximad, widening slightly along length, with curved distal lower margin. Female foreleg with same general setal arrangement as male. Mesotarsal claws long, slightly shorter than length of mesotarsus.  
Lateral lobes of abdominal tergum IV short, broadly rounded, right lobe slightly longer than the left. Right lobe with about 10 long setae and left lobe with about 14 long setae, more or less evenly spaced. Prestrigilar flap of abdominal tergum V compact, with upper and lower margins oppositely curved (Fig. 5e). Strigil indistinct, narrowed, elongate, elliptical in outline. Median lobe of abdominal sternum VII (Fig. 5f) short, apex sharply acuminate, setae restricted to mediobasal portion and consisting of numerous short and long hairs. Free lobe of abdominal tergite VIII (Figs. 5g, 6a) broad, outer and lower margins nearly square, setae dispersed along inner and lower margins, numbering about 22–25. Three to five short spines in lateral portion of upper angle. Entire lobe with scattered small dark areas. Pars stridens processus cleaner ridges of abdominal segment VIII not discernible with light microscopy. Left paramere (Figs. 6b–g) shorter, shaft curved upward and laterally. Tip broad in outline, with peculiar troughlike formation as seen from inner lateral view. Paramere base hatchet-shaped. Right paramere (Figs. 6b–d, f–g) long, twisted, laterally flattened, tip broadly rounded, as seen in ventral view. Base of right paramere long, rectangular (Figs. 6f–h), with about 20 plectral ribs confined to medial portion. Aedeagus broad, very short (Figs. 6b–d, f).  
 Distribution and habitat: (Fig. 7). Indonesian New Guinea. Known only from the type locality. All specimens taken at lights.   
 Discussion: This species is very similar in habitus to other Papuanecta. The morphology of the sternal process of abdominal segment VII and free lobe of abdominal tergite VIII is similar to those of P. minajerwioides; however, the two species can easily be separated by the male parameres. The shape of the prothoracic lobe and metaxyphus serves to distinguish the females of the two species.   
 The species is closely related to P. minajerwi and P. minajerwioides on the basis of the sternal process of abdominal segment VII, and the free lobe of abdominal tergite VIII. The sternal process of abdominal segment VII in P. sinistra is also similar.
