Distribution
This native Nearctic species is reported in Canada for the first time from New Brunswick, Quebec, and Ontario (Map 1). In the USA, new records are provided for Massachusetts and Minnesota, and an additional record is provided for New York. The species was previously reported from Indiana, Michigan, New York and Wisconsin (Erichson 1839[1], Casey 1910[5], Bland 1865[2], Blatchley 1910[3], Moore and Legner 1975[4]).
Natural history
Most adults from Quebec were collected in yellow birch and balsam fir dominated forest using pitfall traps (Klimaszewski et al. 2007b[6]). In New Brunswick, adults were found: under decaying seaweed on sea beach; under driftwood on a riverbank; in grass, moss and leaf litter near water in alder and cedar swamps and Carex marshes; in Spagnum moss and leaf litter in a young regenerating mixedwood forest; and in other decaying material in forests. In Ontario, adults were captured in litter around raspberry bushes near a bog, in a Typha marsh, and in a nest of Microtus pennsylvanicus. Adults were active from March to October in Canada. In Minnesota, adults were captured on a lakeshore and in a Microtus nest, and in Indiana were taken by sifting dump vegetable debris from March to November (Blatchley 1910[3]).

Comments
In new material of Mocyta from Quebec and New Brunswick, we discovered an unrecorded bicoloured species from Canada that was similar in body size, coloration and shape of spermatheca to the native Mocyta luteola (Erichson) and the European Mocyta negligens (Mulsant & Rey) and Mocyta gilvicollis (Scheerpeltz). After examining the types and additional specimens of the two European species and Mocyta luteola and comparing them with Canadian individuals of our new species, we have concluded that our populations represent Mocyta luteola and that they are not conspecific with the two European species, as they differ in external morphological features such as body proportions, microsculpture, and shape and pubescence of pronotum. After examining the types of both nominal species (Mocyta negligens, Mocyta gilvicollis), and additional specimens from Europe, we found no significant morphological differences between the two species. Therefore these two European species are considered as conspecific, and Mocyta gilvicollis is considered as a new synonym of Mocyta negligens with details listed below (Figs 9a–g, 10–14).
Colpodota negligens Mulsant and Rey 1873[7]: 156 (Figs 10–14); Benick and Lohse 1974[8] (as Mocyta); Smetana 2004[9] (as Acrotona).
LECTOTYPE (male): the specimen does not have any original label but it is from the historical Rey collection (CCL) and it is pinned next to the original name label by Rey. It bears V. Gusarov’s lectotype designation label (2000), and his identification label as Atheta fungi (Gravenhorst), 2000. Because this designation was never published, we formally designate this specimen as a lectotype and put our determination label as Mocyta negligens (Mulsant and Rey), J. Klimaszewski 2014.
PARALECTOTYPES: there are 4 syntypes (1 male, 3 females) in Rey’s collection that are here designated as paralectotypes. One of the syntypes (female) bears a black dot label, which indicates that the specimen was taken in Provence, in southeast France. The specimens bear Paralectotype designation labels by V. Gusarov (2000) but because these designations were not published, we formally designate them as paralectotypes. All are determined as Mocyta negligens (Mulsant and Rey), det. J. Klimaszewski 2014.

LECTOTYPE (male): Typus; Atheta (Acrotona) gilvicollis; O. Scheerpeltz [red label]; female sign; Üttligen; IX.1943; ex coll. Scheerpeltz [blue card] (MNHV) examined, present designation.
PARALECTOTYPES: Erlach; X.1951; male sign; gilvicollis ex coll. Scheerpeltz [blue card]; Vienna Museum (NHMV) 1 male, examined; Frauenfeld; VII.1955; gilvicollis Scheerpeltz, ex coll. Scheerpeltz (NHMV) sex undetermined, examined, present designation.
