The specific epithet quadrilobatus means “with four lobes” and refers to the structures on the pronotum. Diagnosis. Dichotomius quadrilobatus differs from other species of the D. boreus species group by the following combination of characters: (1) clypeus with symmetrically transverse carina, upper margin of clypeal carina concave medially (Figs. 1 A–B, D), (2) anterior pronotal edge with margin beaded and distinctly widened medially; superior pronotal lobes with anterior edge obtusely acuminate (forked to transversally truncate in D. boreus) and divergent (closer and not divergent in the other members of the D. boreus species group); external apices of the lobes marked and pointing forward. In addition, remarkable differences are found in the morphology of the male genitalia: apex of parameres pincer shaped (normal in D. boreus); dorsal edges of the parameres parallel and close proximally, clearly divergent near the apex, and convergent apically (dorsal edges close throughout and divergent at the apex in D. boreus); lamella copulatrix differs in shape of the left lobe, whose margin of inferior branch of the bifurcation is broadly rounded (clearly acuminate in D. boreus). To date, D. quadrilobatus, is the largest species within the D. boreus species group, with some specimens exceeding 31 mm in length. Description. Body measurements. Male (Figs. 1A, C–D): length 19–32 mm (holotype 31.2 mm); width 11–19 mm (holotype 18.6 mm). Female (Fig. 1B): length 22.1–27.0 mm in length; width 12.8–17.9 mm. Color. Dorsal side of body black to reddish brown (holotype matt black), antennomeres and mouthparts reddish brown, antennal club dark yellow and dull. Head. (Fig. 1D) Semicircular, wider than long. Clypeal margin feebly sinuate at middle, clypeal surface strongly wrinkled. Clypeal carina high and trapezoidal, located behind clypeal edge. Clypeogenal suture marked, slightly swollen medially. External edge of genae rounded, with small tubercle in proximity of the clypeogenal junction. Frons with trituberculate carina; central tubercle higher than the lateral tubercles, triangular shaped, and with acute apex; lateral tubercles low and wide. Pronotum. Wider than long; anterior pronotal margin beaded, posterior margin wider at the middle, posterior margin of bead obtusely pointed backwards, lateral edges of the pronotum with brown setae. Pronotal surface smooth and bright, with simple, irregular punctures; anterior region declivous. Medial suture deep, dividing the lobes longitudinally forming a “T” with lobes anterior margins (Figs. 1 A–B). Lobes square, outer edges normally with rounded projection at apex. Mediobasal region of pronotum with punctures simple and rounded. Lateral fovea of pronotum located on pronotal anterior ridge that connects superior lobes, ridge above foveae forming carina-like projection. Deeply excavated fovea located between anteromedial and posterolateral edge of pronotum. Thoracic sterna. Proepisternum with small spiniform process between procoxae, procoxae with rounded apex, proepisternal surface heavily punctate anteriorly, punctures ocellate with long setae. Propleural surface pubescent on anterior and lateral regions, glabrous in posterior region. Prosternal surface rough, smooth in the middle, sparsely pubescent, with carina at middle. Mesosternal surface rough, anterior edge feebly rounded, central and posterior regions smooth, anterolateral regions with strong and ocellate punctures associated with long, dense setae. Mesepisternum densely punctate. Metasternal disc finely punctate, with feeble groove at middle. Elytra. Surface smooth, without microsculpture. Striae shallow, more impressed on the elytral disc and apex, striae punctures rounded, separated by at least 1.5 times the size of the puncture. Interstriae feebly convex and with fine punctures. Legs. Profemora, mesofemora, and metafemora completely smooth, with long setae on anterior and posterior edges, Protibial surface smooth dorsally and rugose ventrally, protibial spur acute, directed inwards. Mesotibial and metatibial surface smooth, external edge strongly serrate and internal edge finely serrate, both edges with long setae. Metatibial spur feebly emarginate at apex. Abdomen. Sternites 2–6 without microsculpture and with small, rounded punctures along anterior and posterior edges; posterolateral regions pubescent and with ocellate punctures. Pygidium. Wider than long, surface smooth, with small, dense punctation, margins complete. Male genitalia (Fig. 1E). In dorsal view, parameres narrower apically, sides rather straight and not sinuate, apices rounded and curved inward, assuming the shape of pincers. Dorsal edges of parameres simple, parallel and close proximally and medially, divergent near apex and convergent apically. In lateral view, ventral side of parameres straight, excavated near the phallobase, dorsal side of parameres evenly curved toward apex. Endophallites. Lamella copulatrix (Fig. 1F): horseshoe shaped, with left inferior lobe elongate and developed upward, right lobe distinctly wider, bent upward at the bottom; apex of right lobe bifurcated, superior branch acuminate and directed upward, while inferior branch is widely rounded and directed internally. See Fig. 1F for the remaining endophallic structures. Intraspecific variation. Males and females of D. quadrilobatus are morphologically very similar, but males can be recognized by the shape of the posterior margin of the anterior pronotal bead, which is pointed backward (it is simply curved in females) (Fig. 1B), clypeal carina is narrower in males (clearly wider in females), and the last abdominal sternite is narrower at middle in males (evenly wide in females). Small specimens (about 21 mm) may lack of clypeal carina and have reduced and somewhat rounded pronotal projections. Remarks. Sarmiento-Garcés & Amat-García (2009, 2014) provided a short description, along with two illustrations of the head and pronotum of a Dichotomius species, which was considered by the authors themselves to be a close relative of D. boreus. Although apparently aware of describing a new species, the authors did not provide any new name for this Dichotomius, nor selected any name-bearing type specimen to fix the identity of this species, which was initially called “ Dichotomius af. boreus ” (Sarmiento-Garcés & Amat-García (2009) and later “ Dichotomius (Boreus) sp.” (Sarmiento-Garcés & Amat-García (2014). In both papers, the authors included the species in their identification keys, which would lead one to suppose that they considered the series of specimens examined to belong to a distinct species. It is unknown why these authors did not validate a name for this species under the articles of the International Commission on Zoological Nomenclature (1999). Distribution. This species is distributed in Brazil, Colombia, Ecuador, and Peru and inhabits lowland forests (terrafirme forests), white sand forests (in Peru, locally known as “varillal”), and foothill forests in the Amazon and Orinoco regions (Fig. 5). According to the biogeographical analysis proposed by Morrone (2014), and considering our current knowledge on its distribution, D. quadrilobatus occurs in the biogeographical provinces of Sabana, Napo, and Imeri. This new species has been recorded from 85– 750 m. The record from Santiago, Putumayo Department (1°9’N, 77°0’W), Colombia, which is located at 2000 m, may be erroneous. Temporal data. Collected all months of the year except June and July.Published as part of Chamorro, William, Lopera-Toro, Alejandro & Rossini, Michele, 2021, A new species and distribution records of Dichotomius Hope, 1838 (Coleoptera Scarabaeidae: Scarabaeinae) in Colombia, pp. 193-206 in Zootaxa 4942 (2) on pages 200-202, DOI: 10.11646/zootaxa.4942.2.3, http://zenodo.org/record/460044
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

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

The species epithet “ strenua ” refers to a Roman goddess of the new year, purification, and well-being, and should be treated as a noun in apposition. The name is dedicated to the courageous women from this area of Colombia, that have overcome the armed conflict that affected their region in the 1980s and 1990s. Ecology and distribution. The landscape inhabited by S. strenua is part of the “Rio Melcocho” watershed. Vegetation cover is mostly forest classified by Espinel (2011) as Very Humid pre-Montane forest with influence of sub-Andean and Andean forests (van der Hammen & Rangel 1997). Scattered pastures and plantations are located on the few flat areas of these mountains. The tree canopy average height is 25 m with emergent trees of up to 35 m. Although the canopy is mostly continuous with abundant epiphytes, most timber producing trees have been already harvested, and the remaining forest can be considered as a mature secondary forest. The soils are well drained and covered by a leaf litter layer 10–15 cm thick. Biogeographically, these forests belong to the Magdalena Valley mountain forests in the Tumbes-Chocó-Magdalena province, a key biological hotspot. The new species is part of a dung beetle (Scarabaeinae) ensemble of approximately 45 species including other endemic beetles such as Dichotomius andresi Sarmiento & Amat and Cryptocanthon parvus Howden, and moist forest beetles such as Sylvicanthon aequinoctialis (Harold), Scybalocanthon moniliatus (Bates), and Sulcophanaeus noctis (Bates), frequently collected in the Magdalena Valley. On the phylogenetic placement of Scatimus strenua within the genus Scatimus. The cladistic analysis resulted in a single parsimonious cladogram with length: 122 steps, CI = 0.680, RI = 0.811. The topology of the strict consensus cladogram (Fig. 5) is similar to the one obtained by Génier and Kohlmann (2003). The three species groups were recovered, the S. ovatus clade was recovered as monophyletic with the following non-ambiguous synapomorphies: mesoventrites with a deep anteromedian fossa and with setae medially (232), dorsal portion of paramere widely membranous at juncture medially (551), hook of paramere strongly developed (562). The S. cucullatus clade also was recovered as monophyletic, but with ambiguous synapomorphies: body in dorsal view elongate, lateral edges parallel on median third (11), head with a single straight frontal carina (60), and anterolateral angle of elytron subquadrate (181). Scatimus strenua clustered within the S. strandi clade, supported by a single non-ambiguous synapomorphy: head with a single frontal arcuate carina with lateral extremities anteriorly directed (63), and forming a monophyletic unit with S. onorei + S. erinnyos + (S. strandi + S. strenua), supported by the following two ambiguous synapomorphies: non setiferous punctures of pronotal lateral declivity each with a minute granule medially (141), and posteromedial area of metepisternon flat or concave (301). Updated species checklist. Two species of the S. ovatus clade, S. ovatus and S. fernandezi were already confirmed for Colombia by Medina et al. (2001). Escobar (2000) first reported S. strandi in Colombia but neither he nor Medina et al. (2001) included a locality, possibly causing Génier & Kohlmann (2003) to miss the presence of the species in Colombia. Recently, the presence of S. strandi was confirmed in the department of Meta (Cárdenas et al. 2020) and we here report three additional localities for the species in the departments of Caquetá and Nariño. Scatimus fernandezi previously was recorded in Casanare (Medina et al. 2001; Génier & Kohlmann 2003) and we here add new departmental records from Meta and Putumayo. Scatimus ovatus was reported in Medina et al. (2001) without a precise locality; Génier and Kohlmann (2003) registered it in Magdalena; Solís et al. (2011) mentioned “confer” Scatimus ovatus in Atlántico; González-Alvarado & Medina (2015) reported the species in Bolívar, Magdalena, Sucre, Tolima, and Santander; and Mendivil et al. 2020 from Caldas. Antioquia, Boyacá, and La Guajira are new departmental records (Table 1). A fifth species could be added to the Colombian list when expeditions are performed on the border with Panama. Scatimus erinnyos is registered in Cerro Pirre and the Estación Ambiental Cana (7°45.32’N, 77°41.07’W), Panama, approximately 8 km from the department of Chocó in Colombia. It is possible that S. erinnyos is distributed throughout the continuous Chocó-Darién moist forest, that includes the departments of Antioquia, Cauca, Chocó, Nariño, and Valle del Cauca in Colombia.Published as part of Martínez-Revelo, Diego Esteban, Lopera-Toro, Alejandro & Medina, Claudia A., 2020, Review of Scatimus Erichson (Coleoptera: Scarabaeidae) in Colombia with the description of a new species, pp. 521-534 in Zootaxa 4890 (4) on pages 523-529, DOI: 10.11646/zootaxa.4890.4.5, http://zenodo.org/record/430655

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
