Remarks. Originally described from the USA: ‘Detroit, Michigan, 2; Ann Arbor, Michigan, 1. <the digits mean number of specimens in the original type series>’; the holotype of S. pauperculus was captured from uncertain locality, probably in Michigan. Then it was also recorded (under the name of S. pauperculus ) for Massachusetts and Wisconsin ( Puthz 1971b), as well as for three provinces of Canada ( Puthz 1975, Campbell & Davies 1991). Acting as First Reviser, Casey (1892) himself synonymized S. pauperculus with S. brumalis . But Bernhauer & Schubert (1911) cited S. brumalis erroneously as a junior synonym of S. pauperculus , and this misapprehension was kept by all the subsequent authors. Thus, under Articles 24.2.1 and 24.2.2 of ICZN, the valid name for the species under consideration is Stenus brumalis Casey, 1884 .

New for Indiana.
