(Délye 1971). Distribution. Algeria, Tunisia. Differential diagnosis. Gyne. According to the description (Délye 1971), Oxyopomyrmex emeryi, along with O. krueperi and O. santschii, belong to a group of species that have the genae covered with longitudinal striae without rugosity. In this group, O. emeryi is distinguished by punctation occurring between the longitudinal striation on the lateral surfaces of the thorax. The two other known species from this group are characterized by the lateral surfaces of the thorax bearing longitudinal striation with rugosity or a smooth surface between the striae. Male. Oxyopomyrmex emeryi is one of two known species that is devoid of propodeal spines (Délye 1971). In this group, O. emeryi differs from O. magnus by having the scutellum covered by longitudinal striae on the entire surface, whereas O. magnus has at least the center of the scutellum smooth and shiny, without striation. Worker. Oxyopomyrmex emeryi belongs to a group of species that have distinctly punctate pronotum. In this group, O. emeryi differs from O. polybotesi and O. pygmalioni in the lacking rugosity and longitudinal striae on dorsal surface of pronotum. In comparison with O. oculatus, O. emeryi differs in the occurrence of vertical striation on the dorsal surface of the pronotum and from O. negevensis it can be distinguished by the shining abdomen without a dense layer of appressed micropulpae on dorsal surface of the first tergite.Published as part of Sebastian Salata & Lech Borowiec, 2015, A taxonomic revision of the genus Oxyopomyrmex André, 1881 (Hymenoptera: Formicidae), pp. 1-66 in Zootaxa 4025 (1) on pages 8-11, DOI: 10.11646/zootaxa.4025.1.
Oxyopomyrmex pygmalioni Salata & Borowiec, 2015, sp. nov.
No full textOxyopomyrmex pygmalioni sp. nov. (Figs. 61, 62, 63, 84) Etymology. Named after the Cypriot king Pygmalion. According to Ovid’s narrative, Pygmalion was a sculptor who fell in love with an ivory statue which he had carved. Through Aphrodite’s blessing the sculpture changed to a woman and the king could fortunately married her. Oxyopomyrmex pygmalioni is the most densely and distinctly sculptured species, reminiscent of a raw sculpture. Type locality: Cape Drepano, Cyprus. Type material.

At first glance O. polybotesi is very similar to O. pygmalioni but it differs in following features: the shiny gena without rugosity (while O. pygmalioni has the gena dull and distinctly rugose), the occurrence of distinct longitudinal striae on the lateral surfaces of the pronotum (in O. pygmalioni the lateral surfaces of the pronotum are rugose with a slight longitudinal striae) and the dorsal surface of pronotum is shinier, weaker rugulose with longitudinal striae at the posterior edge (in O. pygmalioni the dorsal surface of pronotum is distinctly rugulose to rugose, and striation,if present, is oblique).Published as part of Sebastian Salata & Lech Borowiec, 2015, A taxonomic revision of the genus Oxyopomyrmex André, 1881 (Hymenoptera: Formicidae), pp. 1-66 in Zootaxa 4025 (1) on pages 50-53, DOI: 10.11646/zootaxa.4025.1.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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

Whole surface of petiolar node microgranulate and microreticulate, dull, postpetiole mostly microreticulate only top partly smooth and shiny. Whole surface of propodeum microreticulate, dull. First gastral tergite smooth and shiny. Male genitalia stout (Figs 10 –13), in lateral distinctly slightly constricted before apex with obtuse inner angle, top shortly and sparsely pubescent, ventral and dorsal margins of parameres shallowly incised, top of inner margin of paramere before apical denticle straight, without dentiform plate extending beyond the sharp edge of paramere (Fig. 13). Differental diagnosis. Tetramorium atlante and T. semilaeve at first glance look similar, and workers are especially difficult to identify. Males and gynes, however, have constant differences in the morphological characters and biometric data (see Table 1). Workers of T. atlante differ from workers of T. semilaeve (in parentheses characters for T. semilaeve) in brown to dark brown body (usually pale yellow to yellowish brown, occasionally brown), head sculpture with longitudinal rugosities, more distinct spread over the frontal surface with very small lateral areas without striation (rugosities less distinct on sides of frontal surface, usually with longitudinal areas without striation). Nevertheless, dark and strongly sculptured workers of T. semilaeve are extremely similar to T. atlante and a proper identification requires a nest sample with sexual forms. Workers of T. depressum Forel and T. punctatum Santschi, two other well-defined species of T. semilaeve complex, differ in reduced sculpture of head with at least half frontal surface smooth and shiny. Gynes of T. atlante distinctly differ from gynes of T. semilaeve (characters for T. semilaeve in parentheses) in larger size with ML 1.848–1.850, MW 1.11– 1.35, CW 1.148–1.187 and SPL 0.212–0.223 (1.053– 1.813, 1.0–1.14, 0.978–1.161 and 0.173–0.201 ), scutum at base and laterally with striation extending from base to at least half length of scutum (scutum completely smooth and shiny or with short striation at base never extending to half length of scutum), scutellum with distinct striation in angles (completely smooth and shiny or with rudiments of striation), anepisternum in posterior half with distinct striation and microreticulation (mostly smooth and shiny), katepisternum along posterior margin with broad area of distinct sculpture (narrow area or reduced to posterior corners), postpetiole less transverse and more sculptured with smooth and shiny area reduced to the middle of top (postpetiole more transverse, less sculpture with whole dorsal surface smooth and shiny). Males of T. atlante distinctly differ from males of T. semilaeve in higher petiole with NOH 0.19–0.235 and PEH 0.313–0.346 (0.156–0.179 and 0.257–0.313), lower SL/CS ratio 0.395–0.421 (0.436–0.478), head behind eyes trapezoidal (rounded), scutum between sutures mostly striate and microreticulate (mostly smooth and shiny), scutellum at whole base microreticulate and striate (completely smooth and shiny or in basal corners with fine sculpture), propodeum slightly angulate (round), anepisternum in posterior half with oblique striation (smooth and shiny, at most with few striae close to upper margin), katepisternum in both upper corners with broad microreticulate and striate area (narrow sculptured areas), male genitalia in lateral view distinctly constricted before apex (shallowly constricted) and top of inner margin of paramere without dentiform plate extending beyond the sharp edge of paramere (with dentiform plate). Biological notes. Although locus typicus Kairouan in Tunisia is placed only 70 m a.s.l. Cagniant (1970, 1997) noted than T. atlante prefers mountainous habitats. Its known localities are mostly between 1600 m (our material) to 2300 m (Haut Atlas). Ants were collected in agricultural habitat such as farmlands, pastures, and in scrubs, luminous forests, roadsides. Preference for mountain habitats additionally differentiates T. atlante from T. semilaeve, which, according to Borowiec et al. (2015), prefers littoral habitats located usually below 700 m a.s.l. and only occasionally reach to the elevation of just over 1000 m a.s.l.Published as part of Lech Borowiec & Christophe Galkowski, 2016, REDESCRIPTION OF TETRAMORIUM ATLANTE CAGNIANT, 1970, NEW STATUS (HYMENOPTERA: FORMICIDAE: MYRMICINAE), pp. 43-52 in Annales Zoologici 66 (1) on pages 44-50, DOI: 10.3161/00034541ANZ2016.66.1.003, http://zenodo.org/record/26954

Biological data. Borowiec collected this species in the desert wadi located near El Médano. Despite the low temperature (15 ° C) and windy, arid climate of the wadi, which is vegetated by a sparse, halophilic vegetation, worker ants were active, and could be caught between clumps of saline herbs. Other ant species collected at the site were: Camponotus rufoglaucus feae Emery, Monomorium subopacum (Smith), Plagiolepis maura Santschi, Solenopsis canariensis Forel, and Tetramorium depressum Forel. Distribution. Spain: Canary Is. Differential diagnosis. Male. Oxyopomyrmex insularis is the only species known to have the posterior margin of the head distinctly rugulose and completely devoid of striation. Only the center of the frons has a few, fine and oblique wrinkles. These two features easily distinguish the male of O. insularis from other Oxyopomyrmex males. Worker. Oxyopomyrmex insularis belongs to a species group that has a longitudinal striae on the head limited to the center of the frons. Oxyopomyrmex insularis differs from O. emeryi and O. oculatus in lacking punctation on dorsal and lateral surfaces of the pronotum and by occurrence of smooth and shiny surface at the center of the dorsal surface of its pronotum and mesonotum; from O. nitidior it differs in the lack of rugosity on dorsal surface of its pronotum and the lack of shiny and smooth surface at the center of its frons.Published as part of Sebastian Salata & Lech Borowiec, 2015, A taxonomic revision of the genus Oxyopomyrmex André, 1881 (Hymenoptera: Formicidae), pp. 1-66 in Zootaxa 4025 (1) on pages 11-15, DOI: 10.11646/zootaxa.4025.1.
