Bioacoustics of Glyphotmethis holtzi

Description and Diagnosis: Male ( holotype ): Pronotum ( Figs. 1a, c, e ). short and broad with distinct tubercles; prozona high its lobes distinct; lateral projections of mesozona very distinct; metazona flat, very short and broad, its lateral margins straight; angular at apex; male tegmina ( Fig. 1a, c, e ) very short, cover the first 4–5 abdominal tergites; axillary 1 and axillary 2 veins distinct and separated; distal excision of dorsal carina of hind femur distinct; inner side of hind femur strongly darkened with dark blue; inner side of hind tibia dark blue in basal 2/3, red in apical part. Male penis valves ( Fig. 1g , h ) stout apically, their apices strongly curved upwards in lateral view, widened in posterior view; lophi ( Fig. 1i ) with more than 15 dense spines, posterior projection of epiphallus ( Fig. 1i ) concave in middle. Female: ( Figs. 1b, d, f ) Prozona with distinct lobes; lateral projections of mesozona distinct; metazona flat, short and broad, only 1.4 times longer than prozona, 1.7 times wider than long; its hind margin angular; tegmina ( Figs. 1b, d, f ) small, reaching hardly to end of first abdominal tergite, usually shorter in other females, narrowly rounded at apex; distal excision of dorsal carina of hind femur distinct, its ventral carina clearly wavy; inner side of hind femur blackish dark blue, its anterio-ventral margin (stridulatory lamellae) with a small red spot; inner side of hind tibia dark blue in basal part; apical 1/3 turns to red. This subspecies is different from G. holtzi holtzi by the shorter and broader metazona, shorter male tegmina, darker inner side of hind legs (presence of much less red color), and its distribution. It is different from G. holtzi pulchripes by the larger body, flat shorter and broader metazona with its angular hind margin, shorter male tegmina, and its distribution. From G. holtzi turcicus by the larger body (especially in females), very distinct tubercles of pronotum, higher prozona and its distinct lobes, presence of lateral tubercles of mesozona, shorter and broader metazona, clearly shorter male tegmina (reaching always beyond hind knee in G. holtzi turcicus ) and its distribution. The coloration of hind legs is similar to G. holtzi pulchripes and G. holtzi turcicus but it is different from them by the characters given above.

Description and diagnosis: Male ( holotype ): Pronotum (Figs. 4a, c, e) long and narrow; with indistinct and blunt tubercles; prozona low with indistinct lobes, in some specimens prozonal lobes absent; lateral projections of mesozona very indistinct or absent in some others; metazona flat, narrow and long, lateral margins straight, hind margin acute angular; tegmina (Figs. 4a, c, e) long and broad, reaching beyond hind knee; axillary 1 and axillary 2 veins of hind wing distinct and separated; distal excision of dorsal carina of hind femur distinct, its ventral carina clearly wavy; inner side of hind femur dark blue; inner side of hind tibia dark blue in basal part, apical 1/4 red; penis valves (Figs. 4g , h) stout apically, their apices strongly curved upwards in lateral view, widened in posterior view; lophi (Figs. 4i) with more than 20 dense spines; posterior margin of epiphallus (Figs. 4i) with a broad rounded projection. Female: Body size small; pronotum (Figs. 4b, d, f) with small, indistinct tubercles; prozona very low, its lobes indistinct, absent in some specimens; lateral projections of mesozona indistinct; metazona flat, long and narrow, 1.7 times longer than prozona and only 1.2 times wider than long, its hind margin angular; tegmina (Figs. 4b, d, f) pointed at apex, reaching beyond end of first abdominal tergite, mostly to half of second tergite; distal excision of dorsal carina of hind femur distinct, its ventral carina clearly wavy; inner side of hind femur dark blue basally, with an indistinct red spot in anterioventral margin (stridulatory lamellae); inner side of hind tibia dark blue in basal part, apical 1/4 turns to red or reddish-blue in some specimens. This supspecies is different from G. holtzi holtzi by the indistinct tubercles of pronotum, lower prozona, indistinct lateral projections of mesozona and lobes of prozona, narrower and longer metazona, the hind legs with much less red color and distribution. It is different from G. holtzi pulchripes by the indistinct tubercles of pronotum, lower prozona, indistinct lateral projections of mesozona and lobes of prozona, flat and longer metazona with straight lateral margins and distribution. From G. holtzi brachypterus by the lower prozona, indistinct lateral projections of mesozona and lobes of prozona, narrower and longer metazona with acute angular hind margin, much longer male tegmina and distribution. This subspecies is near to G. holtzi holtzi by the long and broad tegmina; to G. holtzi brachypterus by the coloration of hind legs but it is different from them by the characters given above. It has similar long metazona with G. dimorphus but it is different from it by the lower prozona, indistinct pronotal tubercles, lateral projections of mesozona and lobes of prozona; flat metazona and smaller body size.
