Xenelmis granatoides Sampaio, Passos & Ferreira-Jr, 2015, sp. nov.
No full textXenelmis granatoides sp. nov. (Fig. 2 a–c) Diagnosis. This species is distinguished by the combination of three characteristics: (1) pronotum with a pair of median carina, (2) third interval of elytra with a short row of granules, (3) male genitalia with median lobe longer than parameres, apex arrow tip-like, slightly concave apically; parameres wide at base, narrowing toward outward projected apices. Description. Holotype male: total length 1.64 mm; head greatest width 0.34 mm, length 0.19 mm; pronotum greatest width 0.63 mm, length 0.50 mm; elytra greatest width 0.84 mm, length 0.95 mm. Body black, appendages light brown. Head: surface micropunctuated between the eyes; anterior margin of labrum feebly sinuate, with small seta all over the margin; clypeus with small, fine, and sparse seta, anterior margin inconspicuously arcuate; antennae filiform, inserted near dorsal margin of eyes, eleven-segmented, last antennomere fusiform, longer than segments IX–X together; eyes ovate; dorsal margin straight; anterior, ventral, and posterior margin rounded. Pronotum with anterior margin sinuate, strongly convex medially, lateral margin crenate and arcuate, posterior margin three-arcuate; one concavity in each side of median concavity in front of scutellum. Surface opaque, with feeble iridescence and sparse recumbent setae; disc with pair of longitudinal, slightly sinuate carinae, made of row of oblong and flattened granules, beginning on projections on posterior margin, extending up to anterior 1 / 5; sublateral carinae, on posterior 1 / 5, very short, made by row of granules. Elytra shining with anterior margin sinuate, humerus feebly acute, lateral margin crenate, apices projected and rounded; six striae on disc, plus one sublateral; stria made by row of punctures bigger than facet of eyes, separated by less than once its own diameter; elytral intervals with sparse setae, mainly on posterior third; third interval with short carina, as long as three times scutellum length, made by row of granules; fifth and seventh intervals carinate, inner carina longer than outer. Scutellum slightly longer than wide, anterior margin strongly arcuate, lateral margin converging to apex; epipleura tomentose with few sparse granules, broad up to apices projection. Prosternum as long as wide, with granulose and setose surface; prosternal process wide with broad, feebly rounded apex. Hypomeron tomentose with granules smaller than facet of eyes, separated by more than twice its diameter. Mesosternum with wide groove to receive the prosternal process. Metasternum with sparse granules and setae; median smooth impression more conspicuous on posterior 3 / 5. Legs: coxa, trochanters and femora with fine and sparse setae; fore tibia with a fringe of tomentum in apical third of anterior face; median tibia with two fringes of tomentum—one in distal third on anterior face, second in distal half on posterior face; hind tibia with fringe of tomentum on apical 2 / 3 on posterior face; tarsomeres 1–4 with few seta on ventral face, apical tarsomere with dorsal pair of seta, near claws. Abdomen tomentose, with granules and seta similar to those of metasternum; last ventrite with sparse, fine and small seta all over the surface and near strongly convex posterior margin. Male genitalia moderately long and wide. Median lobe much longer than parameres; arrow tip-like apex, slightly concave apically; basolateral apophyses very long (approximately 2 / 3 of phallobase length). Parameres wide at base, narrowing distally, with apices projected outward. Phallobase twice as long as wide. Variation. Female externally similar to male. Total body length varies between 1.53–1.68 mm; head width 0.33–0.35 mm; pronotum width 0.53–0.63 mm and length 0.44–0.51 mm; elytra width 0.76–0.84 and length 0.88–0.95 mm. Comparative notes. Xenelmis granatoides sp. nov., like X. micros, bears a single pair of longitudinal row of granules on pronotum, but the new species has a short row of granules on the third interestrial interval; the last characteristic is absent in X. micros (Hinton 1946). The male genitalia of Xenelmis granatoides sp. nov. resembles that of X. granata, but the pair of sublateral carina on pronotum—characteristic of X. granata group—is absent in new species. With this set of characteristics it is not possible to place the new species in any of species groups. Type material: Holotype. Male.

Elytra longer than wide (1.5: 1), with lateral margin crenulate and subparallel, apices projected and slightly oblique, and elytral sutures apart at apex. Granules all over the elytral surface, bigger than facet of eye, separated by one diameter or less. Striae formed by rows of shallow punctures. First interstrial interval convex basally; second interval with a short submarginal carina extending to the anterior fifth; third interval carinate to anterior third; fifth and seventh intervals carinate from the humerus to the apical 1 / 8, outer carina feebly longer than the inner. Epipleura without tomentum and with granules similar to those of elytra. Scutellum as long as wide with truncate anterior margin, and convex lateral margin. Hypomeron and prosternum with granules bigger than facet of eyes, separated by one diameter. Prosternal process wide, extending beyond the forecoxae; apex of prosternal process rounded with a small median projection. Mesosternum with small deep groove on anterior third, for reception of prosternal process. Metasternum with sparse granules on lateral areas and with a shallow median longitudinal impression. Granules on coxae, trochanters, femora, and tibiae bigger than facet of eyes, separated by 1–2 diameters. Tomentum fringe on apical half on anterior face of foretibiae; apices of middle tibiae with fringe of tomentum on anterior and posterior faces (anterior fringe smaller than the posterior); all tibiae with an apical pair of spines.

Ventrite I with a pair of carinae, each one beginning on the inner margin of hind coxae but not reaching the posterior margin of this ventrite. Ventrite V with acute lobes and convex posterior margin with small seta. Male genitalia with median lobe extending little beyond the parameres; wider at basal third, narrowing toward a truncate apex. Basolateral apophysis approximately 1 / 4 median lobe length. Parameres wider at basal third, narrowing toward apex that bears small setae; parameres apices digitiform, feebly curved inward, with some sensilla. Phallobase longer than wide (1.5: 1), slightly longer than half of genitalia length. Variation. Female externally similar to male. Measurements of body may vary in total length 2.95–3.65 mm; head width 0.62–0.66 mm and length 0.37–0.46 mm; pronotum width 1.07–1.13 mm and length 0.88–0.90 mm; and elytra width 1.31–1.44 and length 2.05–2.30 mm. Comparative notes. Cylloepus nessimiani sp. nov. and C. olenus Hinton, 1945 are the only species that have non-tomentose epipleura, but they differ in the median pronotal impression that is shallow and restricted to the middle 2 / 5 in the new species, and wide and complete on the posterior 2 / 3 in C. olenus (Hinton, 1945). The median impression of C. nessimiani sp. nov. is similar to that of C. typhon, whose impression is less distinct near the anterior and posterior margins. These two species can be distinguished by the lack of a median longitudinal depression on ventrite V in C. nessimiani sp. nov., which is present in C. typhon. The male genitalia of C. nessimiani sp. nov. and C. typhon differ as follows: in the new species the median lobe is wide from base to apex, and the parameres narrow toward the apex, whereas in C. typhon the median lobe narrows toward the apex and the parameres are wide from base to apex, with small processes turned outward. C. nessimiani sp. nov. can be distinguished from C. reitteri due to lacking three characteristics present on C. reitteri: median pronotal impression extending from posterior to anterior margin, a gibbosity on the metasternum, and a tooth on the middle of anterior margin of the prosternum.

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
