Myrmilla (Pseudomutilla)
No full textMyrmilla (Pseudomutilla) sp. Material examined. ‘ YEMEN: Soqotra / Zum Hum, 8.iv.2008 / B. Massa leg.’, 1 ♀ (PLFG). Notes. The only examined female clearly differs from the congenerics recorded from Yemen (see LELEJ & HARTEN 2006), while it shows a remarkable similarity to Myrmilla capitata (Lucas, 1848) in the structure and shape of clypeus, mandibles, mesosoma, and sternal carina, as well as in the general pattern of punctuation, colour and pubescence. However, it is characterized by the occurrence of some light erect setae on T4 and T5, while the same are usually black in the latter species. This character was considered of diagnostic importance in the keys of Myrmillinae given by LELEJ (1985: 96) to distinguish the latter species from a large group that includes M. mavromoustakisi Hammer, 1950, M. tenuitruncata Skorikov, 1935, M. vutshetitshi Skorikov, 1927, M. badchysiana Lelej, 1980, M. atalanta Nagy, 1967, M. filippovi Lelej, 1985, M. meda Skorikov, 1927, and M. skorikovi Lelej, 1985. The identity of the studied specimen can be definitively confirmed only by examination of Myrmilla males from Socotra. In fact, M. capitata was not previously recorded from Yemen by LELEJ & HARTEN (2006), and so far has been known only from the Mediterranean area (LELEJ 2002).Published as part of Cascio, Pietro Lo, Romano, Marcello & Grita, Flavia, 2012, New species and new records of mutillid wasps from the Socotra Archipelago (Hymenoptera: Mutillidae), pp. 525-544 in Acta Entomologica Musei Nationalis Pragae 52 on page 528, DOI: 10.5281/zenodo.534029

Sokotra / Island, / Wadi Kam / 13.i.2010 / Saldaitis leg.’, 1 J (MRCI). Notes. Mutilla kassalina Magretti, 1898, described from Kessala (= Kassalā, Sudan), was recently treated as a junior synonym of Pseudophotopsis aurea (Klug, 1829) by LELEJ & HARTEN (2006); this synonymy is based on the overlapping distribution areas and on common morphological characters in both sexes. However, the status of Pseudophotopsis kassalina f. semiaurata Bischoff, 1920, described based on a male from Eritrea, has not yet been clarified. BISCHOFF (1920: 96) based the distinction of this taxon from the typical form on the absence of the apical fringe of golden pubescence on T1. After the examination of the types of both taxa, we can confirm their morphological identity, as well as that in both specimens fringe on T1 is lacking. Furthermore, according to the original description (MAGRETTI 1898: 42), the fringe has not been indicated as occurring on M. kassalina; that suggests that the distinction of the Bischoff’s taxon may have been based on a misinterpretation of the diagnostic characters truly given by Magretti. In any case, Bischoff expressly gave it an infrasubspecific rank; therefore, according to the articles 45.5 and 45.6.4 of ICZN (1999), the name is unavailable. Distribution. Pseudophotopsis aurea is known from Eritrea, Djibouti and Somalia, and has been recently recorded also from continental Yemen (LELEJ & HARTEN 2006).

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
Dentilla socotrana Cascio & Romano & Grita 2012, sp. nov.
No full textDentilla socotrana sp. nov. (Figs. 14–15) Type locality. Yemen, Socotra Island, Wadi Ayhaft, 12°36.5′N, 53°58.9′ E. Type material. HOLOTYPE: ♀ (NMPC), ‘ Socotra Is.

Lo Cascio & F.Grita’ (PLFG); ♀, ‘ Yemen: Soqotra / Wadi Zerig, 8.iv.2008 / leg. B. Massa’ (PLFG). Diagnosis. A female of Dentilla belonging to the group that includes species without spots of pubescence on T2, head and mesosoma red. Holotype description. Body length: 5.6 mm. Habitus as in Fig. 15. Head pale red, roundish, 1.14 broader than long and 0.9 narrower than pronotum. Surface of vertex shiny, with wide and irregularly lacunose punctuation, while on occipital area surface is matt and rugose and punctuation is smaller; genae finely punctate. Eyes oval, large, clearly protruding from head profile and strongly convex; maximum orbital diameter 0.6 of interocular distance; ratio between maximum and minimum orbital diameter 1: 0.69. Clypeus with prominent upper carina, clearly visible from above, ending in shiny basal tubercle. Mandibles ferruginous, weakly curved, darkish in apical half. Antennae entirely pale reddish, with curved scapes. Mesosoma pale red, subrectangular, 1.14 longer than broad; pronotum just slightly arched, with sharp angles, less rounded and evanescent than posterior ones; lateral margins straight. Surface shiny, with punctuation larger and denser than head; in posterior half, interpuctual spaces very small but protruding in jagged denticles, aligned in arcuate rows parallel to back edge. Scutellar scale large and rounded. Pleurae with slightly rugose surface on mesopleural area. Propodeum feebly arched, without a distinct angle between propodeal and dorsal surface of mesosoma. Legs including calcaria pale red, without salient characteristics. Metasoma in holotype has lost the original black colour (see Variability) and became brown due to permanence in alcohol; metasoma 1.30 broader than mesosoma on its maximum width. T1 0.34 narrower than T2. Surface of T2 sparsely and finely punctate, dorsally with variolate punctures that laterally are larger, denser, and sometime confluent. Pygidial area as in Fig. 14. Pubescence on head yellowish, with recumbent and backward-facing short setae mostly on vertex; erect setae uniformly occurring, longer ones close to eyes and on occipital side; shorter erect setae occur also on clypeal margin and around upper carina, as well as on scapes, pedicels and F1, while all following flagellomeres are just clothed by short pubescence. Mesosoma dorsally covered with recumbent pubescence, with long erect setae on lateral and posterior margins, shorter setae occur on dorsum and on pronotal margin. T2 with long erect scattered yellowish setae and black recumbent setae, sparsely covering surface; posterior margin covered by continuous yellowish-whitish fringe with short and recumbent setae, just slightly forward extended in middle. Pubescence of T3–T5 mixed between long erect and short recumbent yellowish-whitish setae. Felt lines golden, 1.35 longer than their distance from posterior margin of T2. Male. Unknown (see Remarks). Variability. Length range of paratypes 5.5–5.6 mm. Head 1.09–1.19 broader than long and 0.87–0.91 narrower than pronotum. There are no substantial differences from the holotype, except for the colour of metasoma, which is black, and for the occurrence of long erect setae also on legs. Differential diagnosis. Dentilla socotrana sp. nov. is morphologically comparable only with D. arabica (Hammer, 1962), originally described from continental Yemen as Smicromyrme (HAMMER 1962) and recently placed in Dentilla by LELEJ & HARTEN (2006). After the examination of a specimen of D. arabica kept at ZMAN (labelled ‘ Yemen, Wadi Bana / 24.X.1992 / A. van Harten’, det. A. Lelej), we can exclude with certainty the identicality between the new and the latter species, which differs in the following features: larger eyes, both in relation to the head size and in maximum orbital length; clypeus less pronounced and protruding; head in a lateral view truncated forward (more round-shaped in D. socotrana); mesosoma slightly narrowed in the anterior margin; surface of mesosoma finely and densely punctate; scutellar scale small and evanescent; propodeum more clearly truncated, with concave propodeal face; T2 less globose and slightly flattened; small pubescent spot on basal fringe of T2; different streaks pattern on pygidial area (Fig. 13). Etymology. The specific epithet is based on the current name of the island where the species has been found. Biological notes. Data from labels indicate a broad phenology for this species, extended at least from November to April, and a wide distribution on the island. One of the specimens was collected at Homhil (about 1000 m a.s.l.) in a stony area subject to intensive grazing. Other traits of its biology are still unknown. Remarks. Dentilla socotrana sp. nov. is the only female belonging to this genus found at Socotra so far. Therefore, it cannot be excluded that it could represent the opposite sex of the above-described D. purcharti sp. nov. Since the faunistic knowledge of the Mutillidae of the study area is not exhaustive, however, further studies could reveal the occurrence of other species. Furthermore, as males and females of this family are highly dimorphic, it is strongly recommended to establish their proper association after a direct observation of mating pairs under natural conditions (see ROMANO 2004, MANLEY & PITTS 2007), rather than based on the assumption of their sympatry.Published as part of Cascio, Pietro Lo, Romano, Marcello & Grita, Flavia, 2012, New species and new records of mutillid wasps from the Socotra Archipelago (Hymenoptera: Mutillidae), pp. 525-544 in Acta Entomologica Musei Nationalis Pragae 52 on pages 539-541, DOI: 10.5281/zenodo.534029
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
