Chiriqui is the name of the southwestern Pacific province bordering with Costa Rica as well as of the major river in this province. In the Guaymi language Chiriqui means "Valley of the Moon". The species name is a noun in apposition.</p> <p> <b>Type material</b>. Holotype ɗ, <b>COSTA RICA</b>: Guanacaste, Santa Rosa National Park, Bahia Naranjo, 24.viii.1995, T. Pape (INBio; the holotype is in good condition, pinned through thorax and with the terminalia extended and fully visible).

Méndez, bred from <i>Cardisoma guanhumi</i> (SMNH; male teneral and shriveled, terminalia in glycerine); Chiriqui Province, Remedios, St. Lucia, 1ɗ, 24.ix.2003, J. Méndez (SMNH; specimen in poor condition except for terminalia).</p> <p> <b>Description</b>. Male: Length 5.0 mm. Similar to <i>S. kuna</i> except for differences in the male terminalia as described below. Holotype with terminalia partly light brown, paratypes with blackish brown terminalia. Phallic vesica with a long proximal extension much longer than swollen part of distiphallus when measured along the straight, proximal side; vesical extension bifurcated in two flat prongs of unequal length, the shortest one set at a right angle to the longitudinal axis of the vesical extension just proximal to its mid point.</p> <p>Female: Length 4.5 mm.

No full text<i>Hoplacephala oryx</i> sp. nov. <p>Figs 1–4.</p> <p> <i>Type material</i></p> <p> Holotype ♂, <b>NAMIBIA</b>: Khorixas district, Leeukop 664, 19°53' 15'' S– 14°21' 44'' E, 26–30.x.2001, A.H. Kirk­Spriggs & E. Marais, Malaise trap in river bed (NMNW). Paratypes: 5 ♂, data as holotype (2 in NMNW, 1 in NMSA, 2 in ZMUC). The entire type series is double­mounted on small blocks of foam; one paratype dissected and its genitalia glued to a piece of cardboard pinned below the block.</p> <p> <i>Non­type material</i></p> <p> 1 ♀, data as type series (NMNW). The female specimen is not given status as paratype, because conspecificity relies partly on the assumption of a male­female dimorphism similar to other species of <i>Hoplacephala</i>, and further corroboration is needed. See further explanation under the description of the female below.</p> <p> <i>Etymology</i></p> <p> From <i>Oryx</i>, the generic name of the gemsbok, which in itself is derived from the Latin (and Greek), <i>oryx</i> = pick or pick­axe. The species epithet is a noun in apposition and refers to the elongate pair of frontal setae, which may be reminiscent or at least suggestive of the long, slender horns of the gemsbok, with which the present species shares its habitat.</p>Published as part of <i>Pape, Thomas, 2006, A new species of Hoplacephala Macquart (Diptera: Sarcophagidae) from Namibia, with a discussion of generic monophyly, pp. 57-68 in Zootaxa 1183</i> on page 59, DOI: <a href="http://zenodo.org/record/2645993">10.5281/zenodo.2645993</a>

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Phylogeny of Rhinophoridae and Polleniidae (Diptera): toward the evolution of Oestroidea
No full textCalyptrates are a megadiverse, actively radiating, group of dipterans, which are widely spread and abundant in nearly all terrestrial environments. Despite huge diversity and economic importance, their phylogeny is far from resolved. Recent attempts employing few taxa seem converging in retrieving monophyly for most of the families and subfamilies, but deep relationships among these, especially for those of the oestroid clade (blow flies and relatives), are labile when not changing. The goal of the present project is to shed some light on the deep phylogenetic relationships among Calyptratae by using an anchored hybridization approach with a careful taxon sampling. Furthermore, we aim at resolving the generic phylogeny of two key families of parasitoid flies: Rhinophoridae and Polleniidae.
Rhinophorids are interesting because of their peculiar parasitoid habit: they are the only insects having exploited crustaceans (Crustacea, Isopoda, Oniscidea) as hosts. Moreover, adult rhinophorids are difficult to recognize from other oestroids due to the lack of autapomorphies. Differently, however, the preimaginal instars present sound autapomorphies. Notwithstanding the several phylogenetic investigations conducted so far, the phylogenetic position of the rhinophorids is ambiguous and there is an impelling need of improving both taxon sampling and sequence data in order to gain a better resolution.
In turn, the phylogenetic position of the polleniids as sister group of the Tachinidae is becoming consensus recently, but the phylogenetic relationships within the family are still unknown.
In conclusion we aim to reconstruct a solid phylogeny of these groups in order to build up a stable and predictive classification of the Oestroidea

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
