Leptorhoptrum robustum  (Westring, 1851)

Beschreibung

Cymbium kürzer als Pedipalpentibia. Embolus stark sklerotisiert. Paracymbium sehr einfach. Epigyne mit breiter Epigynenplatte, Hinterrand ± gerade. Durchscheinende Receptacula seminis klein und kugelig. Prosoma braun, mit dunklem Rand und Radiärstreifen. Sternum braun, schwärzlich übertönt. Cheliceren braun, kräftig. Beine gelbbraun, ± kurz, kräftig. Opisthosoma grau bis fast schwarz.

Körperlänge Männchen: 3-4.2 mm
Körperlänge Weibchen: 3-4.8 mm
Zusätzliche Informationen

In Moos und Laub feuchter, kühler Orte vom Flachland bis zur alpinen Zone.

Es ist beschrieben worden, dass diese kleine Art wiederholt Arbeiter in einer Abwasserreinigungsanlage gebissen haben soll (Duffey & Green 1975). Es scheint sehr unwahrscheinlich, dass eine 3 mm kleine Linyphiide Menschen beissen kann, andere Effekte wie etwa allergische Reaktionen können jedoch nicht ausgeschlossen werden.
