Introduction
TheCollembola, commonnameSpringtail, are
a group ofarthropods, little known because of
theirsmallsizeandcryptichabits.However,the
class is abundant, widespread and species-rich
with a high proportion ofspecies endemic to
Australia. Genera in some families include a
high proportion of endemic species (short-
range endemics), an example being the genus
Temeritas Delamare Deboutteville and Mas-
soud, 1963.
Species of Temeritas are easily recognised as
mm
they are globular, up to 2 long, usually
brightlycoloured with purple stripesandspots
and slender antennae that are longer than the
headandbodycombined(Figs 1,2,3).
The genus has a predominantly pantropical
distribution although, exceptionally, somespe-
cies inAustralia and NewZealand are restrict-
edtotemperateclimates.Atpresent, 47species F(iWgo.me1r.slPeeyn)abnydJMinBketdsrcahwing of Temeritas regalis
are known in the genus, ofwhich three have
been described from Australia (Bellinger etal

collectedfromTasmania.
Systematics
Among the other genera ofglobular Collem-
bola in Australia, Temeritas is distinct because
ofthe relatively large size ofspecies (nearly 2
mm
long), their strongly annulated antennae
that are longer than the body, and attractive
colour patterns and bands (Fig. 1). Species of
Temeritas can be distinguished from Sminthu-
rus,inwhichgenus Womersley(1934) firstde-
scribed thesouthernAustralian species, bythe
lack ofan internal spine on trochanter III and
theshorterantennae. Thereisonlyone species
