Basal cell on fore wings heptagonal, cubitus anterior and median veins originate separately. Cubitus posterior and median veins closer at base. Cubitus posterior anal veins not combined at base or apex. Fore wings with 8 apical cells and CuA1 wider than other apical cells (Fig. 1-C). Hind wing hyaline with yellowish venation and with 6 apical cells.
Operculum. Opercula yellow generally with brown spot on lateral base and white pile, broadly rounded apically, approaching one another and meeting medially.
Abdomen. Abdominal tergites blackish with white pile more or less located near the anterior edge of each tergum. Generally tergites one to seven with a light area on posterior apical part. Timbal cavity exposed. Timbal cover incomplete, blackish or brownish yellow with white short pile dorsally. Timbal with 11 ribs (Fig. 12). Abdominal sternites yellowish. On sternite II blackish area and on sternite III blackish spot at the base in the middle. Epipleurites yellowish.
Pygofer.blackish brown dorsally, yellowish brown ventrally. Posteriorly bow-shaped and sparsely setae dorsa-laterally, smooth dorsally, ventral slightly wavy (Fig. 2). Dorsal beak higher than upper lobe of pygofer and acute. The aedeagus bipartite basally, ex tending apically in a pipe shape, at apex pointed appendages like lamellae (Fig. 3). Sternite VIII concave basally, widened in the middle and slightly narrows to apex (Fig. 4).

Males of Cicadatra platyptera make sounds by using the timbals and fore wings. We were able to record clearly three different types of song, these are: calling song with repeating echemes, produced obviously by timbals like in the close related species Cicadatra atra; courtship song produced obviously by a combination of timbale echemes and wing clicks, which is also typical for courtship songs of some other Cicadatra species (Boulard 1995); and alarm song, which is produced in most cicadas when disturbed or handled. These signals are loud sounds that are widely thought to deter predators (Claridge 1985, Fonseca 1991). Both calling song and courtship songs can last without interruption for many minutes while alarm sounds can last only for one or two seconds.
The phrases of this song are produced by the timbals (Fig. 5B, D). The calling song consists of echeme sequences and intervals between echemes. Echeme duration is in average 122.7 (50-188) ms and interval duration between echemes average 91.2 (40-213) ms (Figs 6, 7). Echeme duration of the calling song if produced after the courtship song (Fig. 5D) is slightly different, in average 133 (75-277) ms and intervals between echemes are in average 80 (36-212) ms long. Calling song sometimes starts with irregular echemes lasting 5-15 ms (Fig. 5A).
The spectrum of these acoustic signals includes frequencies from about 5.5 to 12 kHz with a maximum 6 kHz, 8 kHz and 10 kHz (Fig. 18).
The phrases of this song are produced by the timbals and fore wings in succession. This song develops from the calling song, lasts for some minutes and an individual can continue with another sequence of calling song. The calling song consists of an echeme sequence, and wing clicks in the middle of the intervals between echemes (Figs 8-10). Each echeme averages 104 (83-132) ms and interval durations between echemes average 132 (48-176) ms. The duration of the courtship song is about one or a few minutes (Figs 5C, 8, 9, 10).
The spectrum of these acoustic signals includes frequencies from about 5.5 to 12 kHz with a maximum between 6 kHz and 6.5 kHz (Fig. 19). The courtship song wing clicks, amplitude spectra showing audible frequencies ranging from about 1.7-4.6 kHz and with a maximum 3 kHz (Fig. 20).
When the animals are disturbed, they may produce these sounds. We evaluated a total of 6 recordings of alarm sounds of 6 different animals. The alarm sounds consist of irregular echemes in terms of duration, but generally one can find similar sound patterns or elements in different animals. The alarm song lasts 1300-1350 ms, and consists of 7 elements (Fig. 11A). Elements A last 74-81 ms, elements B last 46-50 ms (Fig. 11B), elements C last 206-210 ms (Fig. 11C), elements D last 77-80 ms, elements E last 60-62 ms (Fig. 11D), elements F last 36-38 ms and elements G last 36-38 ms (Fig. 11E). The interval between elements A and B is 104-107 ms, between B and C is 50-53 ms, between C and D is 63-64 ms, between D and E is 107-109 ms, between E and F is 319-323 ms and the interval between elements F and G is 91-94 ms.
The spectrum of these acoustic signals includesfrequencies from about 5.5 to 12 kHz with a maximum about 8 kHz (Fig. 21).
