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
Copidosomopsis orientalis Yu & Zhang, sp. nov.
No full textCopidosomopsis orientalis Yu & Zhang, sp. nov. (Figs 1−6) Description. Female. Body length 0.8 –1.0 mm. Body dark brown, head and thorax with purplish green sheen; scape yellow except dorsal margin at apex brownish, pedicel and flagellum dark brown; tegula dark brown; coxae of all legs dark brown; fore leg with femur except apex dark brown, tibia generally yellow except dorsal margin marked dark, and tarsus generally yellow except apex brown (Fig. 3); mid leg with femur except apex dark yellowish-brown, tibia generally yellow but median part often brownish, tibial spur yellow, and tarsus generally yellow except apex brown (Fig. 4); hind leg with femur except base dark brown, tibia yellow but subbasally often brownish, tarsus generally yellow except apex brown (Fig. 5). Head. Head in dorsal view nearly 2 × as wide as frontovertex; ocelli forming an angle of about 100 º; antenna (Fig. 1) with scape about 5.5 × as long as broad; pedicel about 1.2 × as long as F 1; funicular segments shortening distad, F 1 about 1.5 × as long as broad, F 6 broader than long; clava solid, obliquely truncate at apex, the truncated part about half clava length. Thorax. Mesoscutum with raised sculpture of polygonal cells, scutellum with same sculpture but apically smooth; fore wing about 2.2 × as long as broad (80 / 36), venation as in Fig. 2. Gaster. Gaster about as long as thorax; ovipositor sheaths (Fig. 6) slightly exserted. Relative measurements: HW 35, FW 18, OOL 1, OCL 2, OD 2.5, MT 32, OL 24. Male. Unknown. Host. Unknown. Distribution. China. Holotype. Ƥ, CHINA, Anhui, Xuancheng, vi. 2003, ZL Sha. Paratypes. 6 Ƥ, same data as holotype; 3 Ƥ, CHINA, Fujian, Jiangle, 10.vii. 1991, coll. CM Liu. Recognition. Copidosomopsis orientalis is similar to C. arenicola (Trjapitzin, 1967) in general coloration and habitus. Copidosomopsis arenicola was originally described by Trjapitzin (1967) from Primor'ye Kray of Russia and redescribed by Kazmi & Hayat (1998) based on material from India. Based on the original description of C. arenicola, C. orientalis can be separated from C. arenicola by the postmarginal vein being absent (Fig. 2) as compared to present though short in C. arenicola, basal cell of fore wing with more setae (Fig. 2) than in arenicola (basal cell with sparse setae as in Fig. 8) and truncated part of clava occupying half its length (Fig. 1) rather than ¾ its length as in C. arenicola.Published as part of Yu, Fang, Zhang, Yan-Zhou, Zhu, Chao-Dong & Tu, Li-Hong, 2010, A taxonomic study of Chinese species of Copidosomopsis Girault (Hymenoptera: Encyrtidae), pp. 55-62 in Zootaxa 2490 on page 59, DOI: 10.5281/zenodo.19558
