Identification
Distinguished from the closely related Negalius marmoratus by structural modifications correlated with its distinctive , including for substrate-supported mounting and leg positioning during mating. Specific morphological diagnostic features require examination of primary taxonomic literature.
Distribution
North America
Behavior
Male courtship involves substrate-supported mounting where the male is supported primarily by the substrate rather than the female's body. The male positions its middle legs anteriorly and performs tactual stimulation by curling its around the female's antennae while simultaneously stimulating her maxillary with its middle legs. These display bouts alternate with periods of male throughout courtship. Genital insertion attempts are rare and occur only prior to copulation.
