Thus the 4,000 or so
described Jumping Spiders in the world are grouped under the family Salticidae.
(Scientific family names of animals always end with the suffix -idae).
the basis of their structure and habits, the 30,000 or so named species
of spiders in the Order Araneida in the world are placed in more than
70 families which in turn are subdivided into smaller groups called
genera. Each genus comprises one or more species.
The little iridescent green Fighting Spider (right) which many Singapore
children are familiar with is a member of Family Salticidae and is
given the scientific name Thiania
bhamoensis. Thiania is the name of the genus to which
the Fighting Spider Thiania bhamoensis belongs.
scientific name is often followed by the name of the person who first
described the animal, and the year of description. Thus, the Fighting
Spider is referred to by scientists as Thiania bhamoensis Thorell
1877, meaning the spider was first described by the Swedish arachnologist
T. Thorell in 1877. If the name of the person is given in brackets,
it means the spider was first described as a member of a different
genus and has since been transferred to the genus now represented
in the current scientific name. An example is the Huntsman Spider
(Linne) 1767. Linne first gave the name Aranea venotoria to
the spider in 1767 but Thorell decided to transfer the spider to the
genus Heteropoda in 1878. Linne's name thus appears within
Under the binomial system, the name of each plant and animal should have
two components (the generic and scientific name) as described before. However,
many Singapore spiders depicted on this website are given only a generic
name, followed by the letters "sp." (short for "species").
This means the spider belongs to that particular genus, but it cannot be
given a specific name. This is sometimes because it is new to science and
has not been properly described and named. In other cases, the spiders may
have been named, but the original descriptions are so vague that accurate
identification becomes impossible.
