In Stein’s key (1911), <i>C. mallochi</i> runs to <i>C. iniqua</i>, but the presence of vittae on the scutum and spots on the abdomen can separate it from <i>C. iniqua</i>. In Malloch´s key (1934), <i>C. mallochi</i> runs to <i>C. inaequalis</i>, but the presence of black strong setae on coxae can separate it from the male of <i>C. inaequalis</i>.</p>Published as part of <i>Patitucci, Luciano Damián, Couri, Marcia Souto & Mulieri, Pablo Ricardo, 2021, The killer flies Coenosia Meigen (Diptera: Muscidae) of southern South America: the Coenosia chaetosa species group with two new species, and notes on male terminalia patterns, pp. 1499-1519 in Journal of Natural History 55 (23 - 24)</i> on pages 1508-1510, DOI: 10.1080/00222933.2021.1954711, <a href="http://zenodo.org/record/5469868">http://zenodo.org/record/5469868</a>

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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

Body length-to-width ratio 1.6. Forebody 196. Tegument armed with minute spines densely covering entire body. Oral sucker subterminal, rounded, 59 × 74. Ventral sucker round, 66 × 65. Oral sucker width-to-ventral sucker width ratio 1.1. Prepharynx very short, 10; pharynx rounded, 44 × 42. Oesophagus short, 30. Caecal bifurcation immediately anterior to ventral sucker; caeca short, terminating approximately at level of middle of ovary.</p> <p>Two testes, very large, distinctly lobed, opposite, longitudinally elongated, immediately post-ovarian; anterior margin of testes reaching anteriorly level of mid-section of ventral sucker. Right testis 169 × 125, less testis 201 × 125. Copulatory pouch 125 × 50, median, directly dorsal to ventral sucker; proximal end of copulatory pouch extends posteriorly beyond ventral sucker; anterior end comma-shaped, curved. Genital pore submedian, sinistral, immediately extracaecal, at level of caecal bifurcation.</p> <p>Ovary 83 × 67, subspherical, immediately posterodextral to ventral sucker, pretesticular.Seminal receptacle not well observed. Mehlis’ gland and Laurer’s canal not observed. Vitellarium extensive, in the form of numerous irregularly shaped follicles forming fields of follicles from the level of the pharynx to posterior end of body. There are almost no follicles in the testicular area, although there is a narrow field of follicles immediately posterior to the testes. Some vitelline follicles are positioned in the middle third of the body between the two main fields. Uterus ventral to gonads, reaching posteriorly between testes to level of mid-length of testes. Metraterm weakly defined, 50 in length. Uterus containing numerous eggs, 38–39 × 17–19. Excretory pore terminal. Excretory vesicle Y-shaped. Details of its organization could not be examined due to overlap with other organs.</p> <p> <i>Remarks</i></p> <p> <i>Paracryptotropaperuviana</i> clearlybelongswithintheCryptotropidae based on its morphological characteristics and the results of our molecular phylogenetic analysis (Fig. 1). At the same time, the phylogenetic analysis strongly suggests that <i>Pa. peruviana</i> represents an independent genus-level lineage (Fig. 1). <i>Paracryptotropa peruviana</i> differs from sequenced representatives of other cryptotropid genera by 4.7%–7.7% of nucleotide positions in the partial 28S gene (Table 2) and by 19.0%–20.3% in the partial <i>cox1</i> gene (Table 3).</p> <p> Morphologically, the new genus is most similar to members of <i>Cryptotropa</i> and <i>Pseudocryptotropa</i>. The new genus differs significantly from species of <i>Cryptotropa</i> in the position of the copulatory pouch and the genital pore. Unlike <i>Pa. peruviana</i>, the copulatory pouch in members of <i>Cryptotropa</i> are nearly or entirely preacetabular, and the genital pore is very close to the less margin of the body. In the new genus, the genital pore is submedian, very close to the less caecum. The new genus can be differentiated from <i>Pseudocryptotropa</i> most easily in the position and orientation of the copulatory pouch. In the new genus, the copulatory pouch is oriented longitudinally and is mostly overlapping with the ventral sucker, whereas in <i>Pseudocryptotropa</i> it is transversally oriented, with only the proximal end of the copulatory pouch sometimes slightly reaching the ventral sucker. Eggs in <i>Pa. peruviana</i> lack polar filaments characteristic of members of <i>Pseudocryptotropa</i>.</p> <p> The new genus differs from <i>Cephalouterina</i> in several morphological characteristics. With the exception of the metraterm, the uterus in <i>Pa. peruviana</i> does not extend anteriorly past the level of ventral sucker bifurcation, whereas in <i>Cephalouterina</i> it reaches oral sucker. The testes in the new genus are situated more posteriorly than in <i>Ce</i>. <i>dicamptodoni</i>. Vitelline follicles in the new genus extend posterior to the testes and reach the posterior end of the body, whereas in <i>Ce. dicamptodoni</i> they barely reach the level of the posterior margin of the testes.</p> <p> The new genus differs from <i>Renschetrema</i>, <i>Rohdetrema</i> and <i>Armadoatrium</i> (see Discussion and diagnosis below) in a number of morphological features, the most obvious being the lack of the stylet and stylet sac.</p> <p> Thus, a combination of molecular phylogenetic evidence and morphology strongly suggests that <i>Pa. peruviana</i> represents a new genus within the Cryptotropidae. The diagnosis of the new genus is provided below.</p>Published as part of <i>Tkach, Vasyl V., Chermak, Taylor P., Patitucci, Kaylyn K., Greiman, Stephen E., Binh, Tran Thi & Olson, Peter D., 2023, Jumping continents and major host lineages: phylogeny and diversity of the enigmatic Cryptotropidae (Platyhelminthes: Digenea), pp. 533-552 in Zoological Journal of the Linnean Society 199 (2)</i> on page 547, DOI: 10.1093/zoolinnean/zlad037, <a href="http://zenodo.org/record/8426187">http://zenodo.org/record/8426187</a>
