''Leucauge'' () is a spider genus of
long-jawed orb weavers, with over 160 species and fully
pantropical
A pantropical ("all tropics") distribution is one which covers Tropics, tropical regions of both hemispheres. Examples of species include caecilians, modern sirenians and the plant genera ''Acacia'' and ''Bacopa''.
''Neotropical'' is a zoogeogra ...
distribution.
The genus was first documented in Scottish zoologist
Adam White's 1841 ''Description of new or little known Arachnida''.
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended fr ...
had suggested the name of the genus and collected the first specimen in May 1832, later named ''L. argyrobapta''.
A vague description and the loss of the only specimen left the genus ill-defined. ''Leucauge'' developed into something of a
wastebasket taxon containing 300 loosely related species, until research in the year 2010 resolved ''L. argyrobapta'' as a synonym of the quite common ''
L. venusta'' and allowed revision and reclassing of the genus. However, a 2018 paper restored ''
Leucauge argyrobapta'' as a separate species.
The body and leg shapes and the silver, black and yellow markings of ''Leucauge'' females make identification of the genus relatively easy. They have two rows of long, slender curved hairs on the femurs of the fourth leg. In most cases the web is slanted rather than vertical and the spider rests in the middle of the web with its underside facing upwards.
