Description

Spiders of the genus Eilica have a total length of 2.2-7.8 mm. The carapace is oval in dorsal view, widest at coxae II, flattened, and narrowed anteriorly. The coloration ranges from light orange to dark brown. The cephalic area is not elevated and the thoracic groove is short and longitudinal. [5]

The anterior eye row is usually only slightly procurved while the posterior row is slightly recurved. The posterior median eyes are irregularly rectangular while other eyes are circular. Lateral eyes are larger than medians. The labium is elongate and spear-shaped. The sternum is rounded and strongly bordered, not extending between coxae IV. The abdomen is light brown to black, longer than wide, with a shiny anterior scutum in males and often a distinct pattern of light spots. The leg formula is 4123. [5]

Eilica may be easily recognized by the two or three translucent laminae found on the cheliceral retromargin and the anteriorly produced chelicerae and convergent endites. [5]
