Araneus praesignis mm) and females (7 mm) of "Araneus praesignis" have large black decorations on the upper rear (dorsal posterior) of the abdomen, thought to be a case of Batesian mimicry where an animal has markings making it appear larger and more threatening than it really is. The spider was described by Ludwig Koch in "Die Arachniden Australiens", 1872. "Araneus praesignis" shelters during the day in a silk-bound retreat made in a non-fully-closed leaf nearby where its web is erected at night. Its food is night-flying insects and other invertebrates. It is harmless to humans and can be handled by people without
Araneus Theridiosomatidae ("Theridiosoma gemmosum", described by L. Koch, 1877 as "Theridion gemmosum"), Titanoecidae ("Nurscia albomaculata", described by Lucas, 1846 as "Epeira albo-maculata") and Uloboridae ("Uloborus glomosus", described by Walckenaer, 1842 as "Epeira glomosus"). "Epeira cylindrica" was at a time placed in Linyphiidae and is considered "incertae sedis", as is ""Araneus" cylindriformis" . "Epeira" was synonymized with the genus "Aranea" by Leach, 1815, and with "Araneus" by Simon, 1904. Throughout the 19th century, "Epeira" was used as a catch-all genus, similar to the once ubiquitous salticid genus "Attus". However, from 1911, to its last mention in 1957, only very few authors continued
