Echemus is a genus of ground spiders that was first described by Eugène Simon in 1878.[3]
Description
Spiders of the genus Echemus have a total length of 5.7 mm. The carapace is longer than wide and yellowish brown, with slightly darker chelicerae. The anterior row of eyes is strongly procurved, with medians light in colour, round, and less than a diameter apart. The laterals are light in colour, oval, slightly smaller than the medians, and very close to them.[4]
The posterior row is very strongly procurved, with medians subangular and close together, distant their long diameter from the anterior medians. The posterior medians are larger than the posterior laterals, which are subequal to the anterior laterals, and about their own diameter from the posterior medians.[4]
The abdomen is testaceous and slightly infuscated dorsally. The inferior spinnerets are short, cylindrical, and nearly their own length apart. The first pair of legs is considerably darker and redder distally.[4]
