    Bembidion perspicuum LeConte 1848

    Bembidion perspicuum LeConte, 1848 Ochthedromus perspicuus LeConte, 1848: 466. Type locality “ Rocky Mountains ”. Holotype male, in MCZ (type number 5510), external structure and aedeagus examined. Bembidion acomanum Casey, 1918: 59. Type locality Jemez Springs, New Mexico, so restricted by Lindroth (1975). Lectotype female, designated by Lindroth (1975), in USNM (type number 36916), examined. Bembidion excursum Casey, 1918: 59. Type locality Tucson, Arizona. Holotype female, in USNM (type 36915), examined. This species is known from Texas, Kansas, Colorado, New Mexico, Arizona, Utah, Nevada, California, and Oregon. Its range in México has not been examined. Specimens from northern California and Oregon are dark, with only elytral apices being pale. They are thus very similar in appearance to paler specimens of Bembidion lugubre, from which they are most readily distinguished by genitalic characters.Published as part of Maddison, David & Swanson, Alexander, 2010, A preliminary characterization of Bembidion perspicuum LeConte, with a reclassification of related species (Coleoptera, Carabidae) north of México, pp. 15-31 in ZooKeys 43 (43) on page 27, DOI: 10.3897/zookeys.43.390, http://zenodo.org/record/57665

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
