C. L. Koch, 1843
Carapace dark greyish-brown with irregular light median and lateral bands. Legs dark greyish-brown. Abdomen light brown, mottled with greyish-black hairs. Paired light spots are present in the median line. Posteriorly, the spots combine to form chevrons. Sternum dark with wide median band which narrows posteriorly. The band is flanked by three light spots at each side. Male similar to female, but with relatively longer legs.

Female 12-18 mm; male 10-15 mm.

Characters of genus:
Anterior row of eyes recurv, posterior slightly procurved. Median ocular trapezium forms a square. Distance between posterior medians only slightly smaller than the distance to adjacent laterals. Clypeus less than diameter of one anterior medial eye. Dorsum of abdomen usually with a dark bordered folium. Venter and sternum with dark bands.

Characters of family:
The araneids belong to the group of ecribellate spider families having 8 eyes and 3 tarsal claws. The eyes are arranged in 2 rows of 4 with the lateral eyes widely separated from the medial eyes. The carapace is often flat with a distinct head region. The chelicers are strong having a lateral condyle (boss at base of chelicer). Labium is wider than long and rebordered (swollen at anterior edge). Maxilla (basal part of palp used for chewing prey) are widest anteriorly. Legs with 3 claws and often furnished with strong spines and trichobothria on all segments except tarsi. Often legs are clearly annulated. The abdomen is usually globose and nearly always with species-specific often bright colour patterns. The abdomens of some species are round-shouldered while others have humps, the latter species often referred to as angulate orb weavers. Some tropical species have large outgrows on the abdomen. A colulus (midline appendage or tubercle) is present in front of the anterior spinnerets. The tracheal spiracle is situated close to spinnerets. Araneids belong to the entelegyne group of spiders often having large and complex epigynes sometimes with a large flexible scapus (finger-, tongue-, or lip-like projection arising in the midline of the epigyne). The male palp is complex.
