Contribution to the knowledge of the endemic Australian genus Binburrum Pollock, 1995 (Coleoptera: Pyrochroidae: Pilipalpinae), with description of three new species
No full textBinburrum Pollock, 1995 is a small group of fire-coloured beetles (Tenebrionoidea: Pyrochroidae: Pilipalpinae) endemic to Australia with five described species. Herein, three new species of Binburrum – B. articuno (southeastern South Australia), B. moltres (northeastern Queensland, Australia), and B. zapdos (northeastern Queensland) – are described based on comparative anatomy, highlighting the underestimated diversity of this genus. Binburrum angusticollis Pollock, 1995 is newly recorded from New South Wales, Australia. Descriptions of new species are supplemented with digital photographs and scientific illustrations of habitus and salient structures. A key for the identification of Binburrum is provided
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

This species is named in honor of the late Karl H. Stephan, collector extraordinare of many obscure groups of “little brown beetles” (among others). I had the privilege of visiting him in 1986, in the company of Milt Campbell; his multiple beetle trap lines and boxes of prepared beetles, many of which were labeled “Red Oak, Oklahoma ”, were very impressive.</p> <p> <b>Diagnosis</b>. Elytra with irregular, lighter colored fasciae anteriorly and isolated spots posteriorly (Figs 13–14); antennae dimorphic, more elongate in males, extended beyond posterior pronotal margin; lateral pronotal margins with 2 tubercles anterad hind angle; male tegmen (Fig. 33) relatively long and narrow, basal piece of tegmen relatively short (length of apicale> 1.5x length of basale).</p> <p> <b>Description</b>. TL 4.1–5.0 mm; GEW 1.2–1.5 mm; TL/GEW (n=6) 3.1 5–3.46.</p> <p> <b>Color</b>. Head and pronotum medium to dark brown dorsally; base color of elytra medium to dark brown; light areas consisting of irregular fasciae (Figs 13–14), in most specimens broken into isolated spots in posterior half of elytra; antennae and mouthparts dark red-brown; legs brown.</p> <p> <b>Head</b> with eyes relatively large, distinctly convex; frons relatively flat, with slight swellings mediad eyes; punctation relatively coarse and deep, punctures separated by less than diameter of single puncture; setae relatively short, directed anteriorly and medially, of two different colors – white/silver and golden; antennae elongate (TL/AL 2.41–2.50 males, 3.47–3.61 females), extending posteriorly to, or posterior of (in some males) pronotal base; antennomeres 4–8 moniliform/subfiliform, slightly sexually dimorphic, shorter in females; antennomeres 9–10 slightly longer than wide in males, slightly wider than long in females.</p> <p> <b>Pronotum</b>. GPW/PL 1.11–1.30; disc slightly convex; punctation relatively deep and dense, punctures separated by much less than single puncture diameter; lateral margins evenly arcuate (in some specimens, lateral margins somewhat sinuate between lateral tubercles), widest point near midlength, marked by tubercle; each lateral carina with 2 or 3 tubercles, the posterior-most of which represents the hind angle; hind angles distinct, short, acute; setae moderately elongate, directed anteriorly and/or medially, color mixed white and golden; posterior bead distinct.</p> <p> <b>Elytra</b>. TL/EL 1.69–1.75; EL/GEW 1.81–2.04; disc moderately convex, evenly sloping to lateral margins; punctation relatively dense and coarse; setae moderately elongate, colors corresponding to dark and light base colors of elytra.</p> <p> <b>Male genitalia</b> (Fig. 33) with apicale very elongate, ca. 1.8X length of basale; apicale relatively slender, ca. 4.0X longer than wide; basale very slightly wider than long.</p> <p> <b>Natural history</b>. No natural history information is known for this species; months of collection range from April to June.</p> <p> <b>Taxonomic notes</b>.

Personal BioBlitz: A New Way to Encourage Biodiversity Discovery and Knowledge in K-99 Education and Outreach
No full textBroad and detailed knowledge about common species in everyday life has decreased among the public. Even biology researchers may be largely unaware of our everyday biodiversity. To counter such 'species blindness' and create long-term excitement and learning about the biodiversity we see every day, we arranged 76-day BioBlitzes at Rutgers University (New Jersey, USA) in 2014 and 2015 where participants identified and listed all species they discovered. The result was 7270/11748 observations from 30/78 participants and 7/13 countries, including 3458/3057 unique taxa, 91%/99.9% identified to species and 80%/54% listed only by one person (2014/2015). Observations of organismal groups did not strongly correspond to number of estimated species worldwide, but appeared to be related to perceived charisma, body size, and organism mobility. Participants reported increased ability to 'see' species and to identify new groups, learning new tools of species identification and strongly increasing their biodiversity knowledge and eagerness to learn more.Peer reviewe
