Figs. 13 , 29 , 43 , 45 , 53–54 , 79 , 95 Holotype (male): Indonesia : Papua , Neth. Ind.-Amer. New Guinea Exped., Araucaria Camp , 800m , 11.III.1939 , lg. L.J. Toxopeus , labelled: " Paramacroxiphus brunneus sp. n. " . Holotype in Museum Zoologicum Bogoriense [Cibinong], Indonesia . Specimens Examined ( Paratypes ): 1 female , Neth. Ind.-Amer. New Guinea Exped., Bernhard Camp, 50m , 27.III.1939 , lg. L.J. Toxopeus (MBBJ); 1 larva (female last instar), do. Araucaria Camp, 800m , 15.III.1939 , lg. L.J. Toxopeus ( MBBJ ) . Description. Fastigium verticis: eye length = 1.8: 2.4 mm ; projecting 1.0 mm in front of eyes. Tegmen rather broad; anterior margin sinuate and tegmen narrowest in circa middle of length. Femora with the following number of spines on ventral margins: profemur 8 external, 6–7 internal; mesofemur 6–7 external, 3–4 internal; postfemur 13–14 external, 14–16 internal. Male. Stridulatory file circa 3.95 mm long, sinuate; teeth large and spaced near base, medium-sized in middle and small and very dense near apex ( Fig. 13 ); with about 120 teeth or 30.4 teeth per mm; in middle with 25.0 teeth per mm; in basal half with 14.0 teeth per mm. Tenth abdominal tergite globose; apical margin concave at each side and slightly prolonged and curved ventro-craniad in middle ( Fig. 29 ). Cerci short, broadconical and somewhat dorso-ventrally compressed; with a lobate baso-internal process, a stout longitudinal carina on internal margin, and somewhat below this carina with a small, finger-shaped, acute, apico-internal tooth ( Fig. 29 ). Subgenital plate with medial carina and deviating margins; in apical half divided into two narrow branches that are deviating and later approaching each other; apical half also curved dorsad; styli thin ( Fig. 43 ). Titillators hardly sclerotised [freshly moulted?] and indistinct; apically connected with a white-hyaline, circa ovoid, lobate sheath; ventrally of this sheath the membrane forms a complex, irregular, yellow-hyaline structure, which carries a small, rugose, lateral lobe and a baso-internal, curved, hyaline spine ( Figs. 45 , 53– 54 ). Female. Tenth abdominal tergite with apex subtruncate but triangularly furrowed in middle. Epiproct small, rounded. Cerci long-conical, slightly curved, apex pointing. Subgenital plate curved dorsad in specimen at hand such that the internal [= dorsal] side is visible; not well preserved. Subgenital plate in central area rhombic, consisting of two separate sclerites connected by membranous areas widening towards base; lateral of the central area with transverse folds with concave surface that might on external [= ventral] side carry additional sclerotised plates ( Fig. 79 ). Ovipositor long; highest in circa middle of length; dorsal margin convex, at base concave; ventral margin concave, at base convex; both margins smooth. Coloration. Reddish brown. Frons including mandibles dark brown; labrum with ventral half of dorsal part yellow; antennal scrobae, scapus and pedicellus partly black. Femora (in larvae also pronotum) dark brown with pale spots (most distinct in larva, in male hardly distinct). Tegmen with dorsal area pale; lateral area dark reddish brown with paler veins and light transverse veinlets in circa basal half, unicolorous in apical area. Measurements: body male 36, female 35; pronotum male 11.7, female 11.3; tegmen male 48, female 51; postfemur male 26.5, female 30; ovipositor 55 mm .
