Bioacoustics of Philmontoides globosus

Description. Elongate species with tegmen nearly reaching end of hind femur ( Figs 9G–H ). Pronotum elongate; disc with anterior margin convex but faintly concave in middle, posterior margin broadly rounded, covering only very base of stridulatory area of tegmen in male; lateral lobes not very deep, ventral margin slightly concave, at end forming a rounded angle with posterior area that is projecting laterad and clearly visible from above. Prosternal spines long; mesosternal lobes obtuse; metasternal lobes rounded with an angle or fold. Femora with the following number of spines on ventral margins: (1) 3-8 / 6-8; (2) 6-9 / 1-4; (3) 11-13 / 9-15 (n = 4); hind knee lobes bispinose; in one male also anterior knee lobe of fore femur bispinose. Male. Stridulatory file in about basal two thirds with large and spaced teeth, after a sinusoidal step, teeth abruptly narrowing and becoming denser and hardly perceptible toward end; total file length 1.32 mm with 38 distinct and about 10 indistinct teeth; area with countable teeth 1.29 mm with 38 teeth; area with large teeth before step 0.92 mm with 17 teeth; area with largest teeth 0.68 mm with 12 teeth (n=1; Fig. 12C ). Tenth abdominal tergite strongly convex with short rounded excision from base, in apical area markedly down curved, hind margin on both sides concave, in middle prolonged into a process with concave lateral margins that shortly after divides into a pair of compressed projections that widen toward tip and embrace an oval space that is open at hind margin ( Fig. 11C ). Cerci with basal rim forming a narrow furrow with a small bump at both sides, afterward rounded, slightly conical and little curved mediad, terminating into a dorsal and a ventral projection; dorsal projection compressed, with narrowing margins, at end rounded with a small, curved spine; ventral projection wide, dorso-ventrally compressed, at end with a triangular ventral projection with straight hind margin and with a small spine below its dorsal hind angle ( Figs 10E–F ). Subgenital plate strongly, triangularly excised from base to almost mid-length, afterward with a fine carinula along midline; central disc at base slightly convex, afterward with little converging lateral margins; margins upcurved and at dorsal end curved laterad, forming in basal half a narrow concave, in apical half a wide convex rim; the plate terminates into a pair of narrow, about rounded projections that carry styli at oblique ventroapical end ( Fig. 11C ). Titillators with basal area long and narrow, running parallel but not fused with each other, at base for a short distance curved sideward; at posterior end curved moderately sideward and widened to vaulted laminar branches; these branches appear in apical view to have the dorsal rims curved in an about 180° angle against each other while the lateral surfaces are strongly bulging on both sides with internal surface more strongly bulging and shorter, external surface less strongly bulging and longer ( Figs 14D–G ). There is also a pair of narrow, wavy lateral sclerites near bases of titillators running vertically to the titillator axis. Female. Subgenital plate with baso-lateral expansions large, oval, and moderately swollen; disc little bent along mid-line forming a stout medial carina; lateral margins converging, ending into a pair of triangular extensions with obtuse tips, hind margin angularly excised in between ( Figs 16I–L ). Coloration. Face of general color, antennal scrobae light or darkened, internal surface of scapus and fastigium verticis brown or black; vertex, occiput and upper area of genae black or dark brown; dorsal surface of pronotum of general color, in posterior area with indication of a dark medial band, lateral lobes black with one or two light spots, margins black but partly of light color; tegmina along anterior and posterior margins of light color, partly with dark spots, in central area dark brown with light veinlets, along central area thickened and blackish brown; hind femur with black pre-genicular ring ( Fig. 16I ). Measurements ( 3 males , 1 female ).—Body w/wings: male 32.5–35.0, female 36; body w/o wings: male 26–30, female 33; pronotum: male 6.5–7.8, female 7; tegmen: male 22–25, female 26; hind femur: male 21.5–23.0, female 24; antenna: male 120–130; ovipositor: female 14 mm .
