Females (n=5, minmax): Total length 1.8-2.3, carapace length 0.7-0-8, width 0.7-0.8, length femur I 0.9- 1.0, tibia I 0.5-0.6 mm. <b>Somatic features, colouration</b> (Figs 63-64). Overall colouration of carapace, sternum, gnathocoxae and chelicerae bright red in living specimens. This striking colour fades in specimens preserved in alcohol. Legs and palps lighter, with distal femora, patellae and distal tibiae reddish, but no dark annulations. Abdomen uniformly dark brown to ruby coloured. Male epigaster sclerotised, seminal vesicle (part of male genital system) conspicuously dark, translucent. <b>Male palp</b> (Figs 60-62). Tibia very short, wider than long, with one retrolateral trichobothrium. Embolar base with anchoring process for tegular notch, as in other <i>Theridion</i> species. Distal part of embolus rather short (0.2 mm long) and stout. Conductor covered with minute scales. Theridiid tegular apophysis straight and pointed, closely adjoining conductor. Median apophysis sickle-shaped. <b>Epigynum /vulva</b> (Fig. 43). Entrance of copulatory ducts distinctly sclerotised, visible through integument. Ducts 0.46 mm long, forming several overlapping, short coils. Receptacula seminis globular. <b>Distribution.</b> Mediterranean region, most records coming from Southwest Europe and North Africa: France (Simon 1914; Denis 1934; type locality Corsica “commun en Corse sur les buissons” Simon 1873a), Spain (Simon 1914), Portugal (Cardoso 2009), Italy (Caporiacco 1922, 1936b), Croatia (present paper), Morocco (Simon 1909, 1914), Algeria (Simon 1914) and Tunisia (Pavesi 1884). More recently, <i>Theridion musivum</i> has also been shown to occur in Sinai, Egypt (Levy 1998).
