Drassodes cupreus is a species of spider in the genus Drassodes, family Gnaphosidae.[1] A ground-living nocturnal hunter, it spends the day in a silken retreat.
Females are 10–18 mm, males 10–13 mm. The carapace (the upper surface of the prosoma) is brownish with a darker border. The abdomen (opisthosoma) is hairy and similarly coloured. The posterior median eyes are closely spaced. In general appearance, D. cupreus cannot be distinguished from other Drassodes species, such as Drassodes lapidosus. Identification relies on the shape of the epigyne in the female, and the arrangement of the teeth on the chelicerae and shape of the palpal bulb in the male.[2][3]
Like other species of Drassodes, Drassodes cupreus is a nocturnal hunter, spending the day in a silken retreat. Mature females are found throughout the year, mature males only in spring and summer.[2]
Drassodes cupreus was first described by John Blackwall in 1834,[1] on the basis of specimens found near Manchester and Llanrwst in Great Britain.[4]
Drassodes cupreus has a Palearctic distribution. It is considered to be generally more common than the related D. lapidosus.[1] It occurs at ground level, under stones, in leaf-litter and around the bases of grass tussocks, often in particularly dry sites.[2] In the south of Great Britain, it is found in heathland.[3]

De gewone muisspin (Drassodes cupreus) is een spinnensoort in de taxonomische indeling van de bodemjachtspinnen (Gnaphosidae).[1] De spin jaagt 's nachts en verschuilt zich overdag onder rotsen en bladeren. Het lijf van de spin is ovaalvormig, smal en puntig aan de achterzijde.
Het dier behoort tot het geslacht Drassodes'. De wetenschappelijke naam van de soort werd voor het eerst geldig gepubliceerd in 1834 door Blackwall.

Drassodes cupreus er en av edderkoppene i gruppen flatbukedderkopper (Gnaphosidae).
Drassodes cupreus er en middelsstor, litt flat edderkopp med kraftige bein. Forkroppen er ganske bred bak, sterkt tilsmalnet forover (smalt hode). Kroppen er todelt i en bakkropp (abdomen) og en forkropp (prosoma eller cephalothorax). De åtte øynene danner to tverr-rader. De midtre øynene i den bakerste raden er mer eller mindre uregelmessig (ikke sirkelrundt) formet.
Artene i denne slekten er ganske like hverandre, samtidig som de kan være fargevariable av utseende. For sikker artsbestemmelse kreves ofte nærmere undersøkelse av de kjønnsmodne edderkoppens genitalier, hos hunner epigynet og hos hanner pedipalpenes siste ledd.
Drassodes cupreus er nattaktiv og bygger ikke fangstnett, men jakter ute i det fri. De bygger seg et skjulested av edderkoppsilke under steiner, mellom død vegetasjon eller lignende steder. Hunnen spinner en eggsekk av edderkoppsilke, hvor hun legger eggene.
