is beautifully coloured, having a brown abdomen with remaining body parts strikingly emerald green. The eyes are surrounded by white rings. Adult males have the carapace light brown, are overall somewhat darker but are rarely seen due to a short season. The unmistakably appearance makes it impossible to confuse it with any other species.
Female 5-6 mm; male 3-4 mm.
Characters of genus:
Carapace with long forward-directed spines. The medial eyes form a rectangle slightly longer than broad. The abdomen is oval and dilated at rear, and with some coverage of long hairs.
Sundevall, 1833 (Typical Crab Spiders).
Characters of family:
The thomisids belong to the group of araneomorph, ecribellate spider families having 8 eyes and 2 tarsal claws.
are arranged in two recurved rows of four with the posterior row usually more curved than the anterior row. The median eyes are the smallest, the laterals on confluent tubercles, with the posterior laterals facing somewhat backwards. The secondary eyes are provided with tapetum. Thomisids belong to a morphologically very diverse family of spiders generally characterized by broad, moderately flattened carapace and abdomen. The carapace is about as long as wide being semicircular, ovoid or slightly elongated sometimes with protuberances. Usually, it is thinly covered by a few erect simple or clavate setae sometimes arising from warts. Most species have lateral bands on the carapace; sometimes the bands reach the edge. The sternum is heart-shaped. Chelicerae are relatively small and weak, adapted for quick kills by biting prey in the head. Cheliceral teeth are absent except in one subfamily. Sometimes there are small teeth (denticles) present on promargin. Endites and labium are frequently longer than wide. Legs I and II are longer and sturdier than legs III and IV. Legs articulate in plane of the body (laterigrade legs). The anterior legs are often provided with series of strong spines on tibia and metatarsi (e.g.
). The abdomen is variable in shape and colour. It may be round, ovoid or elongate, nearly always widest at rear half. It is often covered by scattered
. Abdominal colours vary from bright hues of white, yellow, green, and pink to shades of grey and brown in obscure patterns. The anterior spinners are short and conical and situated close together. A colulus is present in front of the spinners. The tracheal spiracle is situated close to the spinners. The epigyne is small and weakly sclerotized in some species. The epigynes of
species can be highly variable in depth of sclerotization within the same species and females are therefore sometimes difficult to identify by examination of epigynes. The tibia of the male palp is provided with ventral and retrolateral apophyses. Embolus is often long and curved along the rim of the cymbium.
