Male: Antennule with peduncle having three articles; flagellum with three articles, article- 1 with proximal and distal cluster of aesthetascs; article- 2 with distal cluster aesthetascs; article- 3 minute, terminating with four simple setae of varying length. Antenna with one mid-dorsal and two distal (one dorsal and one ventral) setiform spines on the second article. Buccal mass (mouthparts) obsolete. Maxilliped reduced, appearing nonfunctional. Cheliped forcipate with carpus lateral face having length greater than depth; propodus with length about Character Cocotanais Heterotanais Makassaritanai s Ogleus Pseudonototanais Cacoheterotanais gen. n. Antennule peduncle 3 articles 3 articles 3 articles 3 articles 2 articles 3 articles twice depth, ventro-distal margin with pair of subacute processes (one disto-laterally and other disto-medially) to seat long, slightly curved dactylus when closed; fixed finger of propodus directed downward, nearly at right angle to posterior (ventral) margin of propodus, with low tooth or apophysis sub-distally on incisive margin. Uropodal endopod with three subequal articles; exopod uni-articulate, small not reaching past endopodal article- 1. Female: Maxilliped with inner plate having three pairs of long simple setae distally. Uropodal endopod, as in male, with three articles. Type species. Cacoheterotanais rogerbamberi sp. n. Etymology. From the Greek Cacos = bad, plus the generic name Heterotanais. Gender. Masculine. Known range. North America, Gulf of Mexico, Eastern Continental shelf off the Florida West Coast. Remarks. Systematically, the genera within the Pseudonototanais complex (i.e. Cocotanais; Makassaritanais; Ogleus Morales-Núñez & Heard, 2013; Pseudonototanais and Heterotanais) appear to represent a highly derived group displaying a mixture of characters (see Table 1) confounded by the probability of homoplasy. Cacoheterotanais shares a unique combination of some of these characters. The males of Cacoheterotanais and Pseudonototanais have an antennule with three flagella articles, uropods with three endopodal articles, and article- 2 of the antenna with three setiform spines, which appear to distinguish them the other male members of the genus-group. The male of the Cacoheterotanais differs from that of Pseudonototanais by having three instead of two apparent antennular peduncle articles (Figs 10 G, A, respectively) and a chela with a distinctly different fixed finger. The male of Cacoheterotanais, like those of Cocotanais, Makassaritanais, and Pseudonototanais, has an antennule with the first apparent flagella article bearing both proximal and distal clusters of aesthetascs (Figs 10 G, E, D–F, A, respectively). In contrast, only a single distal cluster of aesthetascs is present on first flagella article- 1 for the males within the genera Heterotanais and Ogleus (Figs 10 C, B, respectively). The chela for the male of Cacoheterotanais appears to be transitional between M. bamberi, and those of the genera Cocotanais and Pseudonototanais. The latter two genera lack the sub-distal apophysis or low blunt tooth on the subdistal grasping margin of the fixed finger (Figs 11 E, C, A, respectively). This structure is present in Makassaritanais, Ogleus, and Cacoheterotanais (Figures 11 D, F, B, G, respectively) and maybe homologous with the “teeth” occurring on the fixed finger of males within genus Leptochelia sensu lato. Table 1 presents a synopsis of these and additional characters for separating the genera within the Pseudonototanais complex. The female of Cacoheterotanais differs from those of other genera of the complex by having its uropodal endopod with three articles of similar length; those for the other genera have from 4–5 articles or incipient articles often of variable length. Cacoheterotanais and the other members of the Pseudonototanais complex appear to have more affinities of the Leptocheliinae than the other currently recognized subfamilies as defined by Bamber (2013). There, however, still appears to be confusion in the systematics of this genus-group (see Morales & Heard 2013). Based on the variable morphological features exhibited within it, the generic status of many of the species is uncertain; however, we reluctantly decided to establish the genus Cacoheterotanais to accommodate the new species from the Gulf of Mexico. The designation of a new genus within this group of six mostly monotypic genera is based on sound morphological differences, but at this time we are unable to determine whether or not they are systematically or phylogenetically definitive. Nevertheless, we follow Morales-Núñez & Heard (2013) in believing that until molecular studies can be conducted, the status of genera within the “ Pseudonototanais complex” (as well as for the Leptocheliidae as a whole), cannot be resolved with a high degree of certainty.Published as part of Morales-Núñez, Andrés G. & Heard, Richard W., 2015, Cacoheterotanais rogerbamberi, a new genus and species of leptocheliid Tanaidacea (Crustacea: Peracarida) from shelf-waters of the Gulf of Mexico, pp. 169-188 in Zootaxa 3995 (1) on pages 170-172, DOI: 10.11646/zootaxa.3995.1.16, http://zenodo.org/record/23598

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

Etymology. This species is named in honor of Richard Modlin in recognition of his contributions to the study of the genus Heteromysis of the northwest Atlantic. Habitat. Heteromysis (Olivemysis) modlini collected from rock/sponge/algal washings in back reef and sand/ seagrass habitats in depths of 1– 2 m. Collecting techniques were too general to determine if the species was associated with a specific sessile host. Distribution. This species is known only from waters immediately adjacent to the south coast of Grand Cayman Island. Remarks. Of the 27 nominal species of Heteromysis reported from the western Atlantic, H. (Olivemysis) modlini is most closely related to H. agelas Modlin, 1987, H. bredini Brattegard, 1970, H. (Olivemysis) guitarti Bäcescu, 1968, and H. tuberculospina Modlin, 1987. These species share the following characters: article 3 of antennular peduncle with normally flagellated spiniform seta for both sexes; margins of telsonic cleft with spinules along at least 0.75 length; lateral margins of telson armed with spiniform setae along at least 0.8 length; uropodal endopod with 6 or fewer spiniform setae along medial margin; male pleopods 3 and 4 with modified setae or spines (see Table 1). Heteromysis (Olivemysis) modlini is unique among these species in having bent, attenuated spines (non-articulated cuticular extensions) on male pleopods 3 and 4 while three of the other four species are known to possess flagellated setae (articulated cuticular extensions) or spines. Males of H. bredini have not been described. The new species differs from H. agelas and H. (Olivemysis) guitarti in having the outer apical seta on the telsonic lobes two times or less the length of the inner seta rather than 2.2 times or more. It is distinguished further from H. agelas by the setation of the uropodal endopod (3–4 setae compared to 2) and from H. (Olivemysis) guitarti by having the antennal scale reaching beyond the antennal peduncle as well as more lateral setae on the telson (14–19 compared to 9–14). Heteromysis (Olivemysis) modlini is distinguished from H. bredini by having 10–16 rather than 31 spinules in the telsonic cleft and 6–7 rather than 10 flagellated setae on the carpo-propodus of thoracic endopod 3. Heteromysis tuberculospina differs from the new species in having tubercles on the flagellated seta of article 3 of the antennular peduncle, an antennal scale length:width ratio greater than 3.0 rather than less than 3.0, and 18–20 rather than 10–16 spinules in the telsonic cleft.Published as part of Price, Wayne & Heard, Richard W., 2011, Two new species of Heteromysis (Olivemysis) (Mysida, Mysidae, Heteromysinae) from the tropical northwest Atlantic with diagnostics on the subgenus Olivemysis Băcescu, 1968, pp. 32-46 in Zootaxa 2823 on pages 33-37, DOI: 10.5281/zenodo.20703

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
