Two new Niphargus species from Switzerland. The drawings are scaled to the same size. Top: N. luchoffmanni sp. n. (holotype, male 6.7 mm), bottom: N. tonywhitteni sp. n. (holotype, male 9.1 mm). Both specimens were rearranged digitally after drawing. Missing parts were taken from the right hand side of the specimen and are depicted in grey.
