Taiwan's spiders fall into over 40 families. Relatively large numbers of species have been recorded in the families Psechridae (psechrid spiders), Oxyopidae (lynx spiders) and Theridiosomatidae (ray spiders), but in other families such as Lycosidae (wolf spiders), Salticidae (jumping spiders), and Heteropodidae (brown huntsman spiders-which include the familiar laya), only three to four species have been formally described in each.
台灣蜘蛛分屬四十幾科，除了褸網科、貓蛛科、球體蛛的紀錄較為齊全，其中狼蛛科、蠅虎科、包括大家最熟悉的剌蚜所屬的高腳蛛科，正式發表的都只有三、四種。
