Head distinctly longer than broad, tapering upward; Paraclypei almost equal to clypeus
, lateral margins almost smooth and without tooth; anteocular region of head twice more than remainder of head, antennae five segmented, 1st antennal segment not reaching apex of head, anteocular distance 3.
14), sharply enlarged above clypeus
(near level of antennae in frontal view), with distinct median carina running from fastigium to level of antennae, obsolete ventrad of antennae.
47 wider than longer; clypeus
dark yellow (female) or yellow (male) T.
The neotropical genus Disceratus Scudder 1869 comprises five species of yellowish or reddish brown, short-legged and brachypterous katydids that are distinguished by two knobs or spiniform processes on the clypeus
, and elongated mandibles in males.
Moreover, the female has lateral vertical seta reduced, almost indistinguishable from the setulae around it; clypeus
yellow; and stemites 3-6 with small anterior apodemes (Figs.
Head and pronotum colour: (0) ochraceous, punctures reddish brown in the form of light and dark stripes, clypeus
pale; (1) unicoloured black/blackish-brown, punctures black, thick, with a small ochraceous fascia on posterior margin; (2) brown, with dark-brown punctures.
The genus Cyphonotus Fischer von Waldheim, 1824 differs from all other Palaearctic and NW Oriental genera of Melolonthini by the following combination ofcharacters: body large and stout (26-40 mm), outer margin of protibia with three strong teeth, subapical calcar of protibia missing in both sexes, clypeus
with widely rounded anterior angles, antennal club 4-segmented and very short in both sexes (Baraud, 1992; Medvedev, 1951).
Body surface sculpture as in female, except for densely-haired clypeus
1) (n=2; plus holo-type measurements in parentheses): Length from apex of clypeus
to apex of hemelytral membrane 3.
Color predominantly reddish-brown, except yellowish to light reddish-brown on clypeus
distally, labrum, outer surface of mandible, anterior surface of scape, legs, propodeal triangle, and sterna.
corythus because its cephalic carina is positioned near middle distance of the head; thus the frontal region of head (frons) is longer than the clypeus
(Figure 2a); in C.
Coloration: Head with face mostly white with medium longitudinal brown spot; clypeus
white, mandibles white with apex light brown; antenna ventrally with margin of scape and pedicel white, flagellomeres black with flagellomeres 12-21 white, flagellomeres 11 and 22 light brown.
