''Trichadenotecnum'' is a
genus of insects in the order
Psocoptera, the booklice, barklice, and bookflies. It is one of the largest genera, including over 200 described species.

''Studies on Neotropical Fauna and Environment'' 45(1) 61-66.
The biology of the genus is similar to that of many other booklice. ''T. alexanderae'', for example, feeds on
pleurococcine algae and the female reproduces by mating with a male.

thelytoky, producing eggs without fertilization.

[ The large genus is divided into several ]clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, ...
s, some of which are further divided into subclades. These groups are mainly separated on the basis of the morphology of the genitalia, which is quite variable in this genus. The male genitalia are the most important structures used to distinguish species. Some males have distinctly asymmetrical genitalia.[Yoshizawa, K., et al. (2008)]

In general, these insects have forewings that are about 2 or 3 millimeters long and have variable spotted patterns.[
