Bembidion obscurellum obscurellum (Motschulsky, 1845)

Peryphus obscurellus Motschulsky, 1845a: 27. Type locality: "Kamtschatka [Russia]" (original citation). One syntype in ZMMU (Keleinikova 1976: 208).

Peryphus maritimus Motschulsky, 1850a: 11 [primary homonym of Peryphus maritimus Stephens, 1839]. Type locality: "Kamtschatka [Russia]" (original citation). Syntype(s) location unknown (possibly in ZMMU though not listed in Keleinikova 1976). Synonymy established by Netolitzky (1935a: 32).

Peryphus fuscicrus Motschulsky, 1855b: 79. Type locality: "ad castellum Nicolajevsk peninsulae Kenai [Alaska]" (original citation for Peryphus lucidus (LeConte) sensu Mannerheim, 1853). Syntype(s) in ZMMU (Lindroth 1963b: 338). Synonymy established by Netolitzky (1918: 25). Note. This taxon was described by indication for Bembidion lucidum (LeConte, 1847) sensu Mannerheim (1853: 150).

Bembidium mixtum LeConte, 1863b: 14. Type locality: "castellum Nicolajevsk peninsulae Kenai [Alaska]" (original citation for Bembidium lucidus (LeConte) var. b of Mannerheim, 1853). Two possible syntypes in MCZ [# 5516]. Synonymy established by Hayward (1897: 134). Note. This taxon was described by indication for Bembidium lucidum (LeConte, 1847) var. b of Mannerheim (1853: 114) and therefore the type series consists of the specimen(s) denoted by the reference (ICZN 1999: Article 72.4.4). The two specimens labeled "R[ussian] A[merica]" in MCZ are possibly syntypes received by LeConte from Mannerheim.

Bembidium repandum J.R. Sahlberg, 1875: 78. Type locality: "af floden Varsuga invid hafstranden i ryska Lappmarken (66°20') [= Varsuga River in Kola Peninsula, Russia]" (original citation). Two syntypes [8 originally cited] in ZMH (Silfverberg 1987: 23). Synonymy established by Lindroth (1963b: 338).

Bembidion cribrulum Netolitzky, 1910: 217. Replacement name for Bembidion maritimum (Motschulsky, 1850).

Bembidion caducum Casey, 1918: 80. Type locality: "Cheyenne [Laramie County], Wyoming" (original citation). Lectotype (♂), designated by Lindroth (1975: 119), in USNM [# 36906]. Synonymy established, under the name Bembidion fuscicrus (Motschulsky), by Fall (1922c: 172), confirmed by Lindroth (1963b: 338).

Bembidion albidipenne Casey, 1918: 80. Type locality: "Montrose (6000 ft.) [Montrose County], Colorado" (original citation). Lectotype (♀), designated by Lindroth (1975: 119), in USNM [# 36907]. Synonymy established, under the name Bembidion fuscicrus (Motschulsky), by Fall (1922c: 172), confirmed by Lindroth (1963b: 338).

Bembidion parowanum Casey, 1918: 80. Type locality: "Little Salt Lake, Parowan [Iron County], Utah" (original citation). Lectotype (♂), designated by Lindroth (1975: 119), in USNM [# 36909]. Synonymy established by Lindroth (1963b: 338).

Bembidion petulans Casey, 1918: 81. Type locality: "apparently Colorado" (original citation). Holotype [by monotypy] (♂) in USNM [36908]. Synonymy established, under the name Bembidion caducum Casey, by Nicolay and Weiss (1934: 197), confirmed by Lindroth (1963b: 338).
