Nettorhamphos Kevin W. Conway & Glenn I. Moore & Adam P. Summers 2017, new genus
Nettorhamphos, new genus urn:lsid:zoobank.org:act:39474160-4609-4DA7-8A3F-F80AF79C069D Type species.— Nettorhamphos radula, new species Diagnosis.— A genus of the Gobiesocidae differing from all other genera in this family by unique features of the oral jaws, including: an upper jaw that is much wider and longer than the lower jaw, creating a large gap between the outermost teeth of the upper jaw and those of the lower jaw (vs. upper and lower jaws similar in width and length and without obvious gap between the outermost teeth of the upper jaw and those of the lower jaw or upper jaw only slightly wider and longer than the lower jaw creating a narrow gap between the outermost teeth of the upper jaw and those of the lower jaw); the presence of tiny dagger-like conical teeth of uniform size arranged in multiple rows in both the upper (premaxilla; ~ 1 5 rows) and lower jaw (dentary; ~ 10 rows; vs. single row of conical teeth along both the upper and lower jaws, a few short, staggered rows of incisiviform and/or conical teeth along both the upper and lower jaw, or conical teeth arranged in a broad patch anteriorly tapering to a single row posteriorly along both the upper and lower jaws). It differs further in having the following combination of character states: medial face of dentary lacking an anteromedially directed spine-like process; snout broad, rounded anteriorly, upper lip separated from snout by a shallow groove; adhesive disc double, papillae present along the entire anterior margin of disc region A; patches of papillae present in disc regions C and D; gill openings large, joined across isthmus; a well-developed spine laterally on head, formed by a heavily ossified Fig. 2. subopercle; dorsal and anal fins widely separated from caudal fin; dorsal fin with fewer fin rays than anal fin. Etymology.— A combination of the Greek words M˜gssA (netta), meaning duck, and q%ÁLuo1 (rhamphos), meaning bill, curved-beak. Gender neuter.Published as part of Kevin W. Conway, Glenn I.

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
