The genus Planispectrum combines very small and compact species from Southeast Asia.

In addition to the small size, the flat body and the very short antennae, which are hardly longer than the femura of the forelegs, are characteristic of the genus.

[2][3] The distribution area of the genus extends from South China and Hong Kong over Vietnam, Malay Peninsula, Singapore, Sumatra and Borneo to Java.

A species also described by Redtenbacher in 1906 as Datames pusillus was transferred to the genus Planispectrum by Oliver Zompro in 2004.

[8] Since 2020, a parthenogenetic stock of Planispectrum hongkongense has been in culture as the first representative of the genus in the terrariums of European enthusiasts.

This traces back to a female collected in the Southern District of Hong Kong on November 20, 2019.

The stock is referred to as Planispectrum hongkongense 'Tai Tam' after its exact location and is considered easy to keep and breed.
