Conchaspididae is a small family of scale insects known as false armoured scales because of their resemblance to Diaspididae (but not incorporating exuviae on their body).[2]
Description
[edit]Members of the family Conchaspididae secrete a waxy scale, in common with other scale insects, but the secreted scale does not include the exuviae.[3]
Ecology
[edit]Five of the 30 species are parasites on palms, but none are considered pests.[4] Conchaspis cordiae infests mahogany trees and has been accidentally introduced to Florida from the Caribbean, but does not appear to cause serious damage.[2]
Taxonomic history
[edit]Carl Linnaeus described a single member of the family, now called Conchaspis capensis, in his Centuria Insectorum, but no further species were described until the 1890s.[5] Eleven of the 29 species currently recognised were insects from Madagascar, described by Raymond Mamet. This probably reflects the sampling effort rather than a particular diversity of conchaspidid scale insects on Madagascar.[5]
Conchaspididae was first recognised as a subfamily of the family Coccidae, but it was raised to the rank of family by Gordon Floyd Ferris in 1937.[5]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
