Pterostichus malkini
No full textDistinguishing Pterostichus malkini from other species of P. (Anilloferonia) Four characters readily distinguish P. malkini from P. diana and P. testacea: the number of supraorbital setae, the shape of the male metafemur, the form of the last visible abdominal ventrite of the male just anterior of the apical margin, and the form of the median lobe of the aedeagus. There are other distinguishing characters but these are subtle, are often variable, and sometimes cannot be accurately assessed without access to reliably identified reference specimens. They will not be addressed herein as that would be more appropriate in a broader treatment of Anilloferonia. All known specimens (6) of P. malkini have only one pair of supraorbital setae (Figure 2). All specimens of P. diana (111) (Figure 3) and P. t e s t a c e a (21) (Figure 4) I examined have two pairs of supraorbital setae, with the exception of one specimen of P. diana with two setae on one side and three on the other. The median posterior margins of the metafemora of the three male P. malkini examined are obliquely angulate and the ventral faces of the metafemora are broader at that point than at either end (Figure 5). The posterior margins of the metafemora of female P. malkini (Figure 6) and both females and males of P. diana (male, Figure 7) and P. testacea (male, Figure 8) are shallowly, smoothly arcuate throughout and the metafemora are more or less narrowly cylindrical throughout. The last abdominal ventrite in the three available specimens of male P. malkini has a small, ventrally projecting ridge between the pair of paramedial preapical setae (Figures 9–10). Female P. malkini lack this ridge (Figure 11), although a small preapical protuberance is present. The last abdominal ventrites of females and males of P. diana (male, Figure 12) and P. testacea (male, Figure 13) lack preapical ridges or protuberances. The shape of the median lobe of the aedeagus of P. malkini differs from those of P. diana and P. t e s t a c e a as follows: the median lobe is shorter and less sinuate in lateral view (Figures 14–19) and dorsal view (Figures 20– 22), the right ventrolateral tumidity is much smaller and is very close to the base of the median lobe (versus large and more medially located) (Figures 17–19), the meeting of the shaft of the median lobe and the base is narrowly perpendicular in right lateral perspective (Figure 17) versus being arcuate and broader (Figures 18–19), the apex is shorter in both lateral and dorsal perspectives (Figures 14–22) and in dorsal perspective, the apex is less twisted to the anatomical left and the tip of the apex is more rounded (Figures 23–25).Published as part of Labonte, James R., 2013, Pterostichus (Anilloferonia) diana LaBonte (Coleoptera: Carabidae: Pterostichini), a replacement name for P.

First western Canadian records of Nebria brevicollis (Coleoptera: Carabidae) and establishment of populations in Coquitlam, British Columbia, Canada
No full textThe first western Canadian records of the European carabid, Nebria brevicollis (Fabricius) (Coleoptera: Carabidae), are reported from Vancouver, Coquitlam, and Delta, British Columbia, Canada. A species description is provided to facilitate identification of this new invasive species. In addition, pitfall trap data are presented that demonstrate establishment of populations at four locations in Coquitlam. Trap catches were substantially higher at one anthropogenic meadow site than at three urban forest sites. Potential for further expansion of the range of N. brevicollis in British Columbia and beyond is discussed.Peer reviewedFinal article publishe

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Pterostichus (Anilloferonia) malkini Hatch
No full textRedescription of Pterostichus (Anilloferonia) malkini (Hatch) (Fig. 1) Color: Rufous to dark rufous throughout. Total body length (mandible apices to occiput + middle of pronotum from anterior margin to posterior margin + base of scutellum along suture to elytral apex): 6.2–7.8 mm. Head: Mandibles elongate, with sharp, hooked apices. Frontolateral carinae distinct, well-defined, parallel except anterior of antennal insertions, where each forms an arcuate obtuse angle with the medially directed anteriormost portion; each extending from frontoclypeal suture to supraorbital seta and highest at antennal insertion. Each frontal impression distinct and deeply impressed, extending from posterior half of clypeus about halfway to occiput, straight on posterior half of clypeus and then arcing from antennal insertion mediad, becoming arcuately divergent at posterior extent. Moderately wide, at widest point 0.6–0.7 as wide as widest point of pronotum. Antennae extending about two segments beyond posterior margin of pronotum. Eyes minute, 0.07–0.125 mm long at greatest length, narrowly ovate and from 0.05–0.075 mm wide, facets faintly visible. One pair of supraborbital setae, anterior pair absent. Pronotum: Greatest width 1.1 times greater than length along midline, greatest width about 0.7 of total length from posterior margin, just posterior of anterolateral setae. Anterior angles distinctly protruding beyond truncate anteromedial margin, narrowly rounded at approximate acute angle. Anterolateral setae about 0.75 of total length from posterior margin and adjacent to lateral margin. Lateral margins evenly slightly convex from anterior angles to about midlength of pronotum, thereafter straight and slightly convergent to posterior angles (varying to faintly sinuate at about anterior limits of posterlateral depresssions and parallel just anterior of posterior angles). Posterior angles about 90 0 or narrowly obtuse, narrowly rounded. Posterolateral setae in posterior angles, about twice distance from lateral margins as posterior margin. Posterior margin faintly convex laterad of each posterolateral impression, faintly emarginotruncate between impressions. Lateral explanations more or less evenly narrow from anterior angles to anterolateral setae, then gradually broadening to about anterior limits of posterolateral impressions, rapidly broadening thereafter until reaching posterior margin. Anteromedial impression at most very faint, indicated by row of shallow, large punctures. Median line strongly impressed, extending from about anteromedial impression to just anterior of or reaching posterior margin. Dorsal surface shallowly evenly convex either side of median line to about 0.6 distance to lateral margin, somewhat flattened laterad from there. Posterolateral impressions linear, deeply incised. Dorsal surface between median line and impressions somewhat flattened, but tumid compared to flat or faintly concave areas laterad of impressions. Impressions extend 0.3–0.4 total pronotal length from posterior margin. Areas between median line and impressions with sparsely to moderately dense fine and coarse deep punctures, areas laterad of impressions with sparse fine shallow punctures, sometimes virtually impunctate. Posterior margin with complete marginal bead. Elytra: Total length about 1.7 times combined greatest width of elytra. Anterior margins slightly concave. Humeral teeth from very small and barely visible to sharp and distinct. Expression of parascutellar striae and angular bases of striae 1 highly variable among specimens, including asymmetrical expression in some individuals. Parascutellar stria may coalesce with stria 1, be distinct but not coalescent with stria 1, or be intermittent and not coalescent with stria 1. Angular base of stria 1 may coalesce with stria 1 or be discontinuous with the anterior portion of stria 1. No basal punctures or setae are present. Striae with faint, evenly spaced, elongate punctures. Epipleuron with distinct, narrow, preapical plica, not denticulate at plica. Umbiculate series of stria 8 with five setiferous punctures in anterior series, one at about anterior third, a pair behind middle, a triad anterior of plica. A pair of subapical umbiculate setiferous punctures in stria 7 posterior of plica. Ventral thoracic sclerites: Prosternal process varying from faintly to strongly margined. Prosternum impunctate except for variable scattered coarse, deep punctures along lateral portions. Proepisterna with moderately dense coarse, deep punctures concentrated in anterior 2 / 3. Mesosternum impunctate. Mesoepisterna with dense coarse, deep punctures, most in anterior half along mesepisternal depression. Metasternum impunctate except along lateral portions, which have moderately dense coarse, deep punctures. Metaepisterna with variably distributed scattered coarse, deep punctures. Abdominal ventrites: Ventrites 1 and 4– 6 impunctate. Ventrites 2 and 3 with variable scattered punctures about midway between median and lateral margins. Ventrites 3–5 with a pair of paramedial setae. Female ventrite 6 with two pairs of apical paramedial setae. Male ventrite 6 with a single pair of apical paramedial setae. Male ventrite 6 with a low, vertically directed lobe between the setae and just anterior of posterior margin, this lobe broadly truncate when viewed from purely anterior or posterior perspectives. Female ventrite 6 without a lobe, but with a very small tumidity between the median pair of paramedial setae. Legs: Female protarsomeres 2–4 broadly triangular and lacking ventral squamose setae, protarsomeres 1 and 5 moderately elongate, 5 glabrous ventrally. Male protarsomeres 1 moderately elongate and expanded in apical half, 2–4 larger and broader than in female, 5 as in female; ventral squamose setae on expanded portion of 1 and 2 –3, 4 and 5 lacking such setae. Mesotarsomeres 2–4 in both females and males somewhat short and broad, rest moderately elongate. Metatarsomeres in both females and males moderately elongate. Metatrochanters slender and cylindrical, narrowly rounded at apex. Female metafemora slender, more or less cylindrical, ventral margin smooth and shallowly, evenly convex. Female metatibiae straight in dorsal view. Male metafemora flattened and broadest in anterior and posterior views, with distinct obtuse angle at about 2 / 3 along ventral margin from femoral base, femoral base about 1 / 4 as wide and apex about half as wide as at angle; ventral face with very well defined carinae on either side extending from angle to apex and delimiting a concavity, carinae merging medially at angle to form interior delimitation of concavity. Male metatibiae slightly arcuate in dorsal view. Aedeagus: In lateral view, ventral margin of median lobe meets base at right angle. Right medioventral tumidity of median lobe very small, near base, thus in lateral view ventral margin of median lobe unisinuate with a single concavity near apical third. In dorsal view, tip of median lobe very short, rounded at apex, strongly convex at right extreme and straight along entire apical half of median lobe. Internal sac with a single large, slender sclerotized spine.Published as part of Labonte, James R., 2013, Pterostichus (Anilloferonia) diana LaBonte (Coleoptera: Carabidae: Pterostichini), a replacement name for P.

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
