View in context

The, timbals (acoustic organs) of fifteen genera of the family Cicadidae of Pakistan are examined and illustrated.

The timbals of Pakistani cicadas are shown to be distinct and of value in identifying the local genera.

For example, Moulds (2005, 2012) employed cladistic methodologies analyzing Australian Cicadidae including the use of a few timbal characters.

This paper aims to explore the utility of using variations in timbal and timbal cover structure of the sixteen genera of Pakistani cicadas.

The timbal was dissected from the cicada to produce the line drawings using a Wild Leitz binocular microscope.

A Key to the Cicada Fauna of Pakistan Based on Structural Variation in the Timbals (Hemiptera: Cicadoidea)

Sound is produced when the timbal muscles buckle the timbals, which are chitinous membranes at the base of the abdomen, generating changes in pressure in the abdominal cavity and exiting through the tympana (Young, 1990; Bennet-Clark and Young, 1992; Fonseca and Popov, 1994; Bennet-Clark, 1998).

venosa have been observed in many species of cicadas and probably function to increase intensity of the call by bringing the abdominal air sacs into resonance with the timbals (Pringle, 1954; Young, 1990; Bennet-Clark and Young, 1992).

For purposes of this research, a sound pulse includes the initial pulse produced by the timbal plate and smaller pulses produced by the timbal ribs.

Dominant frequency of a cicada call is determined by resonant frequency of the timbal and abdominal air cavity (Pringle, 1954; Bennet-Clark and Young, 1992; Young and BennetClark, 1995).

Patterns of radiation near the source are influenced by structures that radiate sound into the environment (Young, 1990; Bennet-Clark and Young, 1992; Fonseca and Popov, 1994; Bennet-Clark, 1998) and asymmetries in these near-animal measurements have been attributed to the timbal (Aidley, 1969), absorption of sound by musculature (MacNally and Young, 1981; Jiang, 1989), or absorption by the tympana or cuticle (Fonseca and Bennet-Clark, 1998).
