. The ground colour of the abdomen is the same as the light parts of the carapace. However, most parts are mottled with whitish, reddish-brown and blackish brown spots. The whitish spots form a reticular pattern. Abdomen has one pair of rather small tubercles. Sternum is brown with an arrow-shaped marking in midline.
Female 3.2-3.6 mm; male 2.5-2.8 mm.

Characters of genus:
The species of this genus resemble comb-footed spiders (Theridiidae) due to their globular abdomen, which is higher than long. The abdomen bears one or two pairs of conical tubercles. The dorsal parts of the abdomen are furnished with curved bristle-like hairs. The anterior medial eyes projects on a small tubercle. The distance between the anterior edge of the carapace and the anterior medial eyes (height of clypeus) is about the same as the distance between the anterior and posterior medial eyes. The length of leg I is slightly less than 1⅓ times that of leg IV. The two commonest Danish species of the genus,
, are difficult to separate as they overlap both in general appearance and habitat. The carapaces of the species are light yellowish brown with variable blackish lateral bands, which often reach the margins. I the midline and especially the eye region there are additional irregular blackish markings. Since these markings on the carapace are quite similar for the species, they are not useful for separating the species. The egg sacks of
are very characteristic. The more or less egg-shaped sack is about 4 mm in diameter, and made of yellowish brown silk which is surrounded by loosely woven silk of a darker colour giving the sack a woolly appearance. The sack is suspended by a cord of silk about 1-2 cm long, typically fastened to vegetation, including branches and bark of trees. The sacks are not guarded but abandoned by the female, which set out for more prey to be able to produce more egg sacks. Since
species are nocturnal, and remain hidden during the daytime, the egg sacks often reveal the presence of the species before specimens are found.

Characters of family:
Metatarsi I and II are furnished with a prolateral row of spines. In between the spines there are series of smaller curved spines, which increase in length distally.
