Redescription. Female from Hetaoba, length of body 4.1 mm, and of fore wing 3.1 mm. Head. Antenna as long as fore wing; first flagellomere 1.2 × as long as second one, first, second and penultimate flagellomeres 7.7, 6.4 and 3.2 × as long as wide (Fig. 2); OOL:OD:POL = 19:8:19; length of eye in dorsal view 1.2 × temple (Fig. 9); temple, face and vertex smooth, shiny and setose (Figs 9, 10). Mesosoma. Length of mesosoma 1.5 × as long as high (Fig. 4); pronotal side largely smooth, but posteriorly and medially crenulate and with some rugae (Fig. 3); mesopleuron largely smooth, but medially moderately punctate; median part of mesopleuron glabrous; mesoscutum smooth and with distinct notauli; scutellum smooth, weakly convex and nearly semicircular; scutellar sulcus wide, deep and coarsely crenulate; metapleuron reticulate-rugose; propodeum coarsely reticulate-rugose and with a medio-longitudinal carina. Wings. Fore wing: pterostigma triangular and 2.4 × longer than its maximum width (Fig. 11); vein cu-a distinctly antefurcal; vein r of fore wing 0.6 × width of pterostigma and slender; vein 1-R1 0.9 × as long as pterostigma; basal cells sparsely setose, except near costal cell. Legs. Length of femur, tibia and basitarsus of hind leg 4.6, 5.9 and 7.0 × their width, respectively (Fig. 12); hind basitarsus 1.9 × as long as second tarsus. Metasoma. First metasomal tergite in dorsal view 4.1 × as long as its maximum width and in lateral view 3.7 × as long as wide (Figs 5, 6), and with nearly longitudinal rugae; remainder of metasoma smooth and have many setae (Fig. 7); hypopygium slight shiny and setose. Colour. Black; scape and pedicel largely dark brown, flagellum pale yellowish but yellowish brown apically; mandible ivory except brownish teeth; palpi, and tegulae yellowish; base of hind tibia pale yellowish; apical third of hind coxa, basal half of hind femur and narrowly its apex, yellowish brown; hind trochanter trochantellus and tarsus yellowish; remainder of hind leg more or less dark brown; veins brown; basal 0.6 of pterostigma dark brown, remainder of pterostigma largely yellow and paler than vein 1-R1 (Fig. 11). Variation. First flagellomere 3.6–7.7 × as long as wide; vein 1- R1 of fore wing 1.0-1.2 × length of pterostigma; pterostigma 2.4–3.6 × longer than its maximum width; vein cu-a of fore wing slightly antefurcal or interstitial, but rather frequently distinctly antefurcal (Fig. 11), but usually less than depicted in Fig. 6 in He & Xu (2015); first discal cell of fore wing 2.0–2.7 × longer than high; first metasomal tergite in dorsal view 4.1–4.5 × as long as its maximum width and in lateral view 3.7–4.3 × as long as wide; length of fore wing 4.3–5.5 mm. The types of H. antefurcalis have the hind femur largely or entirely black apically, but especially in females (the depicted type specimens in the original description is a male) the apex is more or less yellow. The fore leg of females is always yellow in the series from Shaanxi (except one female from Luonan with dark brown fore and middle coxae), but in the type series the femur and tibia are more or less darkened. In general, the males of this species have darker legs and pterostigma than the females, but the female from Luonan has the pterostigma entirely dark brown. Male. Pterostigma entirely black or dark brown; fore and middle femora largely and apex of hind femur dark brown; first metasomal tergite less slender; vein 1-R1 of fore wing 0.9–1.2 × length of pterostigma; length of fore wing 3.8–5.0 mm. Biology. Unknown. Distribution. China (Ningxia, Shaanxi, Sichuan). New for Shaanxi. Discussion. After examination of the series from Shaanxi it is obvious that the position of the vein cu-a of the fore wing (distinctly antefurcal or interstitial) as key character is close to useless (as was noticed by Buffington & Copeland (2016) for the Afrotropical H. elgoni). The position of vein cu-a of the fore wing is in both H. elgoni and H. alborzicus highly variable: from far antefurcal to interstitial and in both species specimens are found to have the position very different between both wings (Buffington & Copeland 2016; personal observation). However, their conclusion that because of this observation H. elgoni is a junior synonym of H. rufipes is not accepted. From their well-illustrated redescription it is obvious that two species are involved: H. elgoni with the pterostigma more than 3 × longer than wide and the posterior margin of pterostigma nearly straight (Fig. 13 in Buffington & Copeland 2016) and H. ruficornis (pterostigma about twice as wide as long and its posterior margin curved; Figs. 14, l.c.). Therefore, we re-instate H. elgoni as valid species and include it in the key.Published as part of Zhang, Ruo-Nan, Achterberg, Cornelis Van, Tian, Xiao-Xia, He, Cheng-Yi & Tan, Jiang-Li, 2020, Sexual variation in two species of Helorus Latreille (Hymenoptera, Heloridae) from NW China, with description of female of Helorus caii He & Xu, pp. 570-584 in Zootaxa 4821 (3) on pages 573-577, DOI: 10.11646/zootaxa.4821.3.8, http://zenodo.org/record/440111
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
