No full textAndrena (Rhacandrena) coruscata LaBerge 1977 Comments: This western species was flagged by LaBerge (1977) as potentially occurring in Minnesota, stating: “Two females from Minnehaha, Hennepin Co., Minnesota, seemingly are specimens of coruscata, although the head of one female is missing.” We have not examined these specimens and additional taxonomic investigation is required.Published as part of Portman, Zachary M., Gardner, Joel, Lane, Ian G., Gerjets, Nicole, Petersen, Jessica D., Ascher, John S., Arduser, Mike, Evans, Elaine C., Boyd, Crystal, Thomson, Robin & Cariveau, Daniel P., 2023, A checklist of the bees (Hymenoptera: Apoidea) of Minnesota, pp. 1-95 in Zootaxa 5304 (1) on page 76, DOI: 10.11646/zootaxa.5304.1.1, http://zenodo.org/record/804856

Alloscirtetica weyrauchi Michener, LaBerge & Moure
No full textAlloscirtetica weyrauchi Michener, LaBerge & Moure (Figs. 7–11) This species is distributed from central-southern Peru to central Bolivia, mainly in mountainous areas about 2600 meters above sea level. The description of this species was based on males collected in Tarata (Peru), the same that were studied by Urban, along with other male specimens, in her revision of the species of Alloscirtetica published in 1971. In that paper, she reported males of this species in Bolivia, although the females had never been observed. During travels in northern Chile in 2000, Laurence Packer (York University, Canada) collected males and females of A. weyrauchi in Zapahuira (Region of Arica and Parinacota). These are the first records of this species from Chile (Fig. 11). As the female of this species remained unknown until now, a description is given here to permit its identification. Female (Figs. 7–8) Dimensions: Approximate body length: 9.29; head width: 3.28; forewing length: 6.71; length of F 1: 0.37; length of F 2: 0.15; length of F 3: 0.14. Coloration: black, with distarsi, claws, veins, tegula and pygidial plate dark brown. Punctation: thick and dense on clypeus, forming vertical lines in the distal half. Labrum with finer and less dense punctation. Paraocular and oceloorbital areas with fine and dense punctation. Mesoscutum with fine and scattered punctation, being denser and thicker on scutellum and mesepisternum. Propodeum areolated and with similar punctation of scutellum. Terga with smooth and narrow distal band; the rest of the plate with fine and dense punctation. T 1 with a transversal carina marking the anterior decline of the tergum. Sterna with slightly denser punctation than of terga, and with a distal smooth and yellowish translucent band. Pilosity: white on gena and mesepisternum; the rest of the head and mesosoma with yellowish hairs. Legs with brown pilosity, slightly darker in the hindlegs. T 1 with long and yellowish pilosity in the anterior half, being shorter in the other terga. T 2 to T 4 with distal band of short pilosity, widely interrupted on T 2. T 5 with similar pilosity to the other terga, except for a spot of dark brown hairs in the distal half. T 6 completely covered with dark brown pilosity. Structure: Eyes divergent above. Mandible thick and short, with rounded apex and without subapical tooth. Tibial spur of middle legs slightly angled at the base and with apex straight. Hind tibiae with apically curved spurs. Basitibial plate rounded, flat and opaque; pygidial plate broad and with rounded apex. Material examined: 2 females and 2 males: Chile Region I Chapiquiña Hydro stn, nr Zapahuira 9.iv.00 L.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
