The paramere of Rhagovelia tricoma sp. n. is similar to that of R. rosensis Padilla-Gil 2010 (compare Figs. 34, 35), however R. tricoma may be distinguished by hind femur bearing a row of five spines, and the characteristic proctiger shape with long setae on the posterolateral margin (Fig. 8). In R. rosensis the hind femur bears 9−10 spines and the proctiger lacks setae on the posterolateral margin (Fig. 9).Published as part of Padilla-Gil, Dora Nancy, 2015, Ten new species of Rhagovelia in the angustipes complex (Hemiptera: Heteroptera: Veliidae) from Colombia, with a key to the Colombian species, pp. 71-95 in Zootaxa 4059 (1) on pages 83-84, DOI: 10.11646/zootaxa.4059.1.4, http://zenodo.org/record/23265

The name “ jagua ” refers to San Predro de Jagua, where the type was collected. Comparative notes. Individuals of Rhagovelia jagua sp. n. may be recognized by the armature of the male hind leg, with the femur slightly incrassate and 5.4 longer than wider, with (1 + 7) spines (Fig. 59), and the tibia with a small spur at the apex. The male and female possess glabrous, shining black central spots on abdominal tergites V −VII; the lateral margins of the basal proctiger are slightly concave (Fig. 11), and the male paramere is rounded, bearing three long setae near at the central part (Fig. 38). Superficially this species resembles R. tantilla Drake & Harris, 1933 but the latter taxon is smaller and less robust than R. jagua, with rounded lateral lobes on the basal section of the proctiger (Fig. 12); and the paramere with a triangular apex, and bearing scattered, small setae (Fig. 39). Additionally, it is also similar to R. pacifica Padilla-Gil 2010, but in that species the posterior femur has five spines; the posterior tibia lacks spines; the ratio of the lengths of antennal segments I and II equals 1.7 (versus 2.6 in R. jagua); the male proctiger has the lateral lobes greatly developed and rounded (compare Figs. 11, 13); and the male paramere has a triangular-shape apex and is rounded on the basal section (compare Figs. 38, 40).Published as part of Padilla-Gil, Dora Nancy, 2015, Ten new species of Rhagovelia in the angustipes complex (Hemiptera: Heteroptera: Veliidae) from Colombia, with a key to the Colombian species, pp. 71-95 in Zootaxa 4059 (1) on pages 86-88, DOI: 10.11646/zootaxa.4059.1.4, http://zenodo.org/record/23265

Similar to apterous male in structure and color. Hind femur relatively shorter and less sinuous than in male, with about 6–8 spines on distal half. Shiny black central spot on dorsum of abdominal segments VI –VIII. Abdominal sterna without carina; VII with shiny brown mark. Comments. When describing R. carina, Padilla-Gil (2015) compared it with R. cardia and R. espriella (= R. rosensis, new synonym). According to this author, R. carina could be distinguished from R. cardia by the absence of a heart-shaped shiny black spot on the mesonotum (present in the latter), the male hind femur 7.3 times as long as wide (7.6 in the latter), and by the shape of the paramere. The mesonotum of the types of R. cardia deposited in the ICN is slightly more bare and reflective than in most Colombian species of the angustipes complex, but a heartshaped shiny black spot could not be observed. Evident shiny black mesonotal areas, similar to those that commonly occur on the abdominal mediotergites of species of the complex, are found, for example, in R. calopa (Fig. 5E) and R. sabrina Drake, 1958, but not in R. cardia. The mentioned difference in the length / width ratio of the male hind femur between R. carina and R. cardia (ca. 4%) is very small and can be regarded as intraspecific variation. The development of the hind femur in male Rhagovelia is related to sexual selection and can be quite variable in a single species, with more extreme cases occurring in the collaris and robusta complexes (Crumiére et al. 2019, Magalhães 2019). The differences in paramere shape between R. carina and R. cardia (compare Padilla-Gil 2015: Fig. 30 and Fig. 31) are due to innapropriate preparation of the drawings. The actual paramere of R. cardia (Fig. 19J) is more similar to that drawn for R. carina by Padilla-Gil (2015: Fig. 30). Considering that these differences are either misinterpretations or of minor importance for species discrimination in the angustipes complex, and that no other major differences have been found between the types of both species, we propose the synonymy between R. carina and R. cardia. As can be seen below, both were described from the same area in southern Colombia. Distribution.

Equity and CO2 Emissions Distribution in Climate Change Integrated Assessment
No full textEmissions distribution is a focus variable for the design of future international agreements to tackle global warming. This paper specifically analyses the future path of emissions distribution and its determinants in different scenarios. Whereas our analysis is driven by tools which are typically applied in the income distribution literature and which have recently been applied to the analysis of CO2 emissions distribution, a new methodological approach is that our study is driven by simulations run with a popular regionalised optimal growth climate change model over the 1995-2105 period. We find that the architecture of environmental policies, the implementation of flexible mechanisms and income concentration are key determinants of emissions distribution over time. In particular we find a robust positive relationship between measures of inequalities
