    Abstract The aim of this study is to estimate the population size of Aegla longirostri Bond-Buckup and Buckup, 1994 in a subtropical low-order stream using the mark-recapture technique. We also tested if the Bayesian model is a promising estimator of population size. Data were collected in two periods, in spring 2010 (seven-day sampling) and in fall 2011(five-day sampling). The animals were sexed, measured, marked in the field, and released in the same spots from which they were collected. During the study period, 445 adults were captured (343 in the spring and 102 in the fall). The estimated population size was 1,005-1,028.8 individuals in the spring and 234-236 in the fall, according to the Schumacher-Eschmeyer and Schnabel methods, respectively. The estimated population size using the Bayesian analysis was 950.13 individuals in the spring and 210.08 in the fall. Although the Bayesian model is a more conservative approach, all methods showed similar and relevant estimations of population size.</div

    Aegla platensis Schmitt, 1942 Diagnosis. Anterolateral spine of carapace reaching half of cornea; protogastric lobes moderately raised; rostrum very long in adults, carinate along its entire length; anterior angle of ventral margin of epimera 2 with spine; fourth thoracic sternite raised medially, with scale; proximal outer margin of moveable finger of cheliped bearing lobe with tubercle; palmar crest rectangular, little developed; inner margin of ventral face of ischium unornamented (Bond-Buckup & Buckup 1994). New records. ARGENTINA: Province of Tucumán: River Las Tiapas and Los Membrillos with Ruta 341, 26º 51 ' 19 "S, 65 º 25 ' 51 "W; 707 m, 09.xii. 2001,(UFRGS 3231, 2 M); Loc.Rio Noque, La Cascada, La sala Sr. Javier, FML 0 0 150 (togheter with A. humahuaca). Former distribution. ARGENTINA: Northern and central Province of Buenos Aires, eastern Tucumán, southeastern Catamarca, and southwestern Misiones. BRAZIL: Southwestern Santa Catarina, and Rio Grande do Sul, except its northeastern part. PARAGUAY: Colonia Independencia. URUGUAY: Departments of Colonia and Canelones (Bond-Buckup & Buckup 1994). Present distribution. ARGENTINA: Paraguay River system, Mar Chiquita system, Dulce River – central Province of Buenos Aires (?), eastern Tucumán, southeastern Catamarca, and southwestern Misiones. BRAZIL: Southwestern Santa Catarina, and Rio Grande do Sul except its northeastern part. PARAGUAY: Colonia Independencia. URUGUAY: Departments of Colonia and Canelones. Remarks. Bond-Buckup & Buckup (1994) identified lots MACN 20959 -1, 11857, 23171, and 25931, all from the La Plata River, as A. platensis. However, the first author, during a recent revision of the MACN collection, determined that these specimens are not A. platensis, but another, very similar species. In sampling in tributaries along the right bank of the La Plata River, Province of Buenos Aires, only A. uruguayana was recorded, corroborating the absence of records of A. platensis from the watercourses located in northern Buenos Aires Province. This resulted in changes in its geographical distribution in Argentina, in addition to the new records from the Province of Tucumán. There still remain doubts as to the statement of Schmitt (1942), who mentioned in his description of A. platensis that the lot was collected on “ Isla Flores, which may equally be located near Buenos Aires or in the Department of Canelones in Uruguay. Aegla platensis has been used as an experimental model in the laboratory as well as in the field (for a review see Bueno & Bond-Buckup 2000; Bueno et al. 2000; Bueno & Bond-Buckup 2004; Ferreira et al. 2005; Oliveira et al, 2007; Almerão et al. 2007).Published as part of Bond-Buckup, Georgina, Jara, Carlos G., Buckup, Ludwig, Bueno, Alessandra A.

    ILO Employment Sector Working Paper No. 43, "The price of exclusion: The economic consequences of excluding people with disabilities from the world of work

    No full text
    A crossroads has been reached internationally in terms of the status of people with disabilities in society. Countries worldwide are reviewing laws, policies, programmes and services for people with disabilities with a view to promoting their inclusion in all sectors of society and enhancing opportunities for them to earn a decent living, to contribute to the income of their families, or to make a contribution in the workplace. In parallel, there is a growing recognition that the exclusion of people with disabilities from the labour market has been at great cost to societies. To contribute to the information base used by decision-makers in allocating resources to programmes relating to the employability and employment of people with disabilities, the ILO commissioned an exploratory study of the macro–economic costs of excluding people with disabilities from the world of work. Building on previous research, this study developed a new approach that takes two drivers of economic losses into account: the gap between the potential and the actual productivity of people with disabilities; and thedifference between unemployment and inactivity rates of non-disabled people and people with disabilities. Together, these drivers yield the costs that society has to bear for excluding people with disabilities from the world of work. The approach was tested using data from a selection of ten countries in Asia (China, Thailand, and Viet Nam) and Africa (Ethiopia, Malawi, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe). The overall losses and the relative importance of factors underlying these losses – disabling environment, unemployment and inactivity – are estimated for each country. The studyshows that by combining reasonable assumptions and adequate modeling, it is possible to generate data on the costs of exclusion, even for countries where reliable primary data are generally scarce, and suggests that these data are more robust than those generated by a global extrapolation approach.It is hoped that the exploratory study will be useful to governments in settingpriorities and in ensuring that people with disabilities are included in measures to tackle the effects of the global financial and economic crisis. It will hopefully stimulate debate and further research on the inclusion of people with disabilities from an economic viewpoint. Comments on the pilot study and its findings will be welcomed. Sebastian Buckup was the author of this working paper. The research, carried out with financial support from the ILO/Irish Aid Partnership Programme, was guided by Barbara Murray, Senior Specialist on Disability, and comments were received from Sara Elder, Economist, Employment Trends Unit, Ferdinand Lepper, formerly of the ILO Department of Statistics, and Debra Perry, Senior Disability Specialist. Anna Kealy edited the manuscript and Jo-Ann Bakker prepared it for publication.ILO_Jan_additions_2.pdf: 291 downloads, before Oct. 1, 2020

Dark lateral stripe from humeral region to caudal-peduncle base, overlain by series of chevron-shaped marks formed by dark lines along myosepta between myotomes extending from anterior third of anal fin; only distal tips of chevrons located to midlateral stripe visible, chevron-shaped marks less evident in adults (≥ 3 cm SL). Pigmented muscle septae that form series of chevrons not coinciding with horizontal rows of scales, not aligned with scale edges. Chevrons present in juveniles, immature specimens and adults, without distal extensions. Dorsal region of head and body chestnut brown. Sides of cranium and ventral surface of body light brown, not silvery. Melanophores of humeral region forming two spots. Anterior spot formed by two layers of pigment: brown melanophores distributed in thin superficial layer of the epithelium (Layer 1, Fig. 1), deeper layer of dark melanophores (Layer 2, Fig. 1). Layer 2 forms a polygon-shaped spot consisting of two groups of melanophores that do not precisely overlap, typically forming four-sided spot. Second humeral spot located one scale posterior to anterior humeral spot, arc- or sigmoid-shaped, inconspicuous, covering two to three scales above lateral line. Spot on caudal peduncle absent. Pectoral fins mostly hyaline; melanophores present on distal tips of pelvic-fin rays and interradial membranes of dorsal, caudal and anal fins. Sexual dimorphism Distribution of hooks on fins varying from 12–16 in the pelvic fin, 15–17 in the anal fin; males with longer unbranched rays in dorsal, pectoral and pelvic fins; distal tips of latter two fins extend posteriorly to pelvic-fin origin and anal-fin insertion, respectively. Distribution Amazon River drainages of Peru, Ecuador and Colombia (Fig. 4). Comments on type specimens of Astyanax villwocki Astyanax villwocki was described by Zarske & Géry (1999) based on specimens from the drainages of the Pachitea River in Peru, the Beni River in Bolivia and the Madeira River. However, examination of the type specimens revealed differences among specimens included in the original description. Specimens from the Madeira River (MTDF 2214- 22115; ZFMK 20781) do not have the diagnostic characters of A. villwocki; they lack the lateral stripe (vs dark lateral stripe present) and have a series of chevrons extending along the entire lateral stripe (vs chevron series not surpassing anterior third of anal fin). We therefore re-identify the specimens from the Madeira River as Astyanax boliviensis sp. nov. Astyanax yariguies (Torres-Mejía, Hernández & Senechal, 2012) comb. nov. Figs 4, 12, Table 1 Astyanacinus yariguies Torres-Mejía, Hernández & Senechal, 2012: 501 –506, figs 1–2. Original description, type locality: Rio Cascajales, Colombia. Diagnosis Astyanax yariguies is a member of the orthodus species-group of Astyanax, differing from the other members of the group, except for A. orthodus, in having a short polygonal caudal-peduncle spot (vs a cane-shaped mark that extends anteriorly to a vertical through the posterior anal-fin tip in A. superbus, an elongate mark that extends anteriorly to the humeral region in A. villwocki, and a short nail-shaped spot in A. bopiensis nom. nov. and A. boliviensis sp. nov.; spot on caudal peduncle inconspicuous in A. gandhiae sp. nov., and spot on caudal peduncle pentagonal, but extended towards dorsal and ventral margins of peduncle in A. embera sp. nov.). It differs from A. orthodus by the greater number of maxillary teeth (6 vs 2–3). It differs from most species of the orthodus -group in having 9–10 series of scales between the dorsal-fin origin and the lateral line (vs 7–8, except for A. bopiensis nom. nov. with 7–10). It is distinguished from A. moorii comb. nov. by orbital diameter greater than 31% HL (vs less than 31% HL), interorbital distance more 32% HL (vs less than 32% HL) and upper jaw length less than 35% HL (vs more than 45% HL). Etymology The species name refers to the Yariguíes, the indigenous group that inhabited an area that includes the watershed of the Cascajales River. They fiercely defended their pristine territory for more than 400 years, which likely contributed to the preservation of the species described here. The Yariguíes finally succumbed to invasion and extermination in the mid-20th century. The species name is treated as a noun in apposition (Torres-Mejía et al. 2012). Type material Holotype (not examined) COLOMBIA: 61.9 mm SL, Santander, El Carmen, Magdalena River system (Atlantic coast), Cascajales River drainage, Sucio River, under bridge on the road from El Carmen to Vereda Island (UIST 1752).

Dentary with anterior four pentacuspid teeth, followed laterally by 8–10 teeth smaller, progressively inclined posteromedially, varying from tri- to unicuspid; proportion of tri- vs unicuspid teeth quite variable. Pored lateral line scales 39(2), 40 (4); transverse scales from lateral line to dorsal-fin origin 9(1), 10 (5); scales from lateral line to anal-fin origin 7(1), 8(3), 9 (2); scales from lateral line to pelvic-fin insertion 6(1), 7(3), 8(2). Predorsal midline covered with bilobed medial scales for more than ¾ of its length, naked anteriorly. Dorsal-fin rays iii 9 (6), first simple ray small, easily visible only in C&S specimens, detectable with dissecting needle in non-C&S specimens; second simple ray about half length of third simple ray. Distal margin of dorsal fin slightly convex. Origin of adipose fin anterior to vertical through insertion of last ray of anal fin. Rays of pectoral fin i 10 (1), i 11 (1). Rays of pelvic fin i 7 (2). Rays of anal fin iii 28–30 (8), first simple rays only visible in cleared and stained material (Table 1). Origin of anal fin posterior to vertical line through insertion of last dorsal-fin ray. Total vertebrae 32(1), 35(1), including those of the Weberian apparatus: precaudal centra 16(1), 17(1); last three without pleural ribs; caudal centra 17(1)–19(1). Epipleurals 19–20. Epineurals 30–31, posterior-most epineural occasionally reaching anterior surface of urostyle. Hypurals 7 (2); first dorsal hypural with anterior margin swollen, without projections articulating with urostyle; second and third hypural with anterior margin swollen, contacting urostyle. Pigmentation in alcohol Sides of body yellowish, with reticulated pattern predominant over the lateral surface of the body. Silvery stripe between humeral region and caudal fin, overlain by series of chevron-shaped marks formed by dark lines along myosepta between myotomes extending from upper region of coelomic cavity to caudal peduncle; pigmented muscle septae forming chevrons not coinciding with scale rows. Chevrons without distal extensions both in juvenile and adult specimens. Dorsal region of head and body chestnut brown. Sides of cranium and ventral surface of body light brown, not silvery. Melanophores of humeral region forming two spots. Anterior spot formed by two layers of pigment: brown melanophores distributed in a thin superficial layer of the epithelium (Layer 1, Fig. 1), deeper layer consisting of dark melanophores (Layer 2, Fig. 1). Layer 2 forms a polygon shaped spot, consisting of two groups of melanophores that do not precisely overlap, typically forming foursided spot extending from third to sixth or seventh scale of lateral series. Posterior humeral spot situated two or three scales posterior to the anterior humeral spot, arc- or sigmoid-shaped, inconspicuous, covering two to three scales above lateral-line. Caudal-peduncle spot short, elliptical in shape, not extending anteriorly to vertical through posterior margin of adipose fin. Pectoral, pelvic, dorsal and anal fins hyaline. Pigment present on interradial membranes of middle caudal-fin rays. Sexual dimorphism Males with small hooks on distal tips of rays of all fins: dorsal fin with hooks on third simple ray and on all branched rays; pelvic, anal and pectoral fins with hooks on branched rays; caudal fin with hooks on four middle rays. Taxonomic comments This species is transferred from Astyanacinus to Astyanax because it shares the anteriorly directed V-shaped chevrons along myomere junctions with members of the orthodus species-group. The conspicuous polygon-shaped humeral spot is also similar (Fig. 1), consisting of dark melanophores.

Distribution North and Central-West Brazil. Remarks 1) The lectotype of M. cinctiger seems to be teneral, and differs from M. luizi in the pronotal spots not being completely pigmented and the central elytral spot absent. Aside from these colour variations, there was no detectable difference in the morphology of male genitalia and other morphological attributes. 2) Mycotretus tucuruiensis Alvarenga has a similar penile flagellum and is potentially related to M. cinctiger, but differs from it in the two elytral black bands being conspicuously “serrate” and in possessing a large black mark on the head (Fig. 3A). Aside from that, the examined specimen of M. tucuruiensis has the outer edge of the prosternal process conspicuously convex, compared to that of the examined individuals of M. cinctiger.Published as part of Pecci-Maddalena, Italo Salvatore de Castro, Lopes-Andrade, Cristiano & Skelley, Paul, 2023, Catalogue of Mycotretus Lacordaire, 1842 (Coleoptera: Erotylidae: Tritomini): an annotated, illustrated and historical approach, pp. 1-182 in European Journal of Taxonomy 876 (1) on page 29, DOI: 10.5852/ejt.2023.876.2149, http://zenodo.org/record/809564
