Cicada (Homoptera: Cicadidae) fauna of This Madi Range, Sabah: A survey and overview

During this survey (in September 1996), a total of three cicada species of one genus of the family Cicadidae was recorded for the Trus Madi Range. The three species were Orientopsaltria angustata Duffels & Zaidi, 0. kinabaluana Duffels & Zaidi and 0. montivaga (Distant). Comparison of records indicated the following. All the three species form additional records for the mountain range, with one (0. angustata) as a new record for Sabah and another one (0. kinabaluana) as an endemic species to Sabah. With these, the previous records of cicadas of the mountain range (of one species, Pomponia graecina Distant [Cicadidae]), and Sabah as a whole (of 73 species) have thus increased to four species and 74 species, respectively. Thick cold fogs during the sampling hours at night in this survey (and probably so in the previous occasions), attributed to the fact that the sampling locations were all at high altitudes (1,400-1,600m above sea level), seem to be the main reason why very few cicadas came to the sampling lights, and hence the low species richness recorded
