Trox hamatus Robinson : New Kansas and Nebraska Records

Robinson (1940) described T. hamatus based upon specimens from New Jersey, New York, Pennsylvania, Maryland, South Carolina, and Georgia. Vaurie (1955) did not report detailed locality records in her revision of Trox , but noted that it is a broadly distributed species in the eastern half of the USA and Canada. Ratcliffe and Paulsen (2008) documented the distribution of T. hamatus in Nebraska. However, those records from Brown, Cuming, and McPherson counties are here removed from the distribution of T. hamatus since they are now known to be T. paulseni . Increased collecting efforts in both states will discover new distributional records that will certainly fill in some of the existing gaps between counties.

The distribution of T. hamatus ( Fig. 8 ) follows with the new Nebraska county records since Ratcliffe and Paulsen (2008) and new Kansas records in bold: NEBRASKA: CASS CO. (3): Platte River State Park ; JEFFERSON CO. (6): Rock Creek Station ; JOHNSON CO. (2): Crab Orchard ; LANCASTER CO. (8): Lincoln, Nine Mile Prairie ; NEMAHA CO. (6): Indian Cave State Park ; OTOE CO. (2): Nebraska City ; RICHARDSON CO. (19): Indian Cave State Park ; SARPY CO. (7): Fontenelle Forest ; SEWARD CO. (1): Garland (7 mi. S). KANSAS: BARBER CO. (1): Wolgamott Ranch ; BOURBON CO. (1): Fort Scott ; CHEROKEE CO. (5): Galena, Schermerhorn Park ; DOUGLAS CO. (1): Woodridge Park ; JEFFERSON CO. (8): Lawrence .
