Holotype male labeled: PANAMA, Darién, Parque Nacional Darién, Estación Rancho Frío, Río Perresénico, 117 masl, (08°01.714’ N, 77 ° 72.417 ’ W), 20 -XI- 2014, R. Novelo col. (IEXA). Paratypes, 19 males, same data as holotype; 8 (IEXA), 8 (Museo de Invertebrados, Universidad de Panamá), 3 (NHMW). Ecology. The specimens of P. panamaensis sp. nov. were collected flying over turbulent rapids in the center of the stream, on a sunny day in the tropical rain forest, together with some specimens of Hexanchorus crinitus Spangler & Santiago, and Disersus longipennis Sharp 1882 (Elmidae: Larainae). Etymology. Because this is the first record of the subfamily for Panama, the species name is used as a noun in apposition. Remarks. Psephenops panamaensis sp. nov. can be separated from other known Psephenops species by the combination of the following features [other species in brackets]: body length shorter than 2.4 mm, according to our measurements [all others longer than 2.4 mm]; antennae long, reaching posterior margin of pronotum [short, hardly surpassing basal half of pronotum, P. mexicanus, P. prestone, P. smithi, P. maculicollis, P. spiniparameri, P. argentinensis]; antennae moniliform-serrate [moniliform or filiform in all others except P. grouvellei]; pronotum without tubercles [with 3 small tubercles grouvellei]; elytra with striae [lacking striae, P. mexicanus, P. lupita, P. prestone, P. spiniparameri, P. shepardi; not described for P. smithi and P. grouvellei]; protibiae with denticles [without denticles, P. prestonae; not described for P. grouvellei, P. smithi, P. haitianus, P. argentinensis]; ventral lobes of tarsomere 2 enlarged (e.g. extending distally completely covering tarsomeres 3 and 4, and basal 0.80 of tarsomere 5) [ventral lobes of tarsomere 2 shorter, not reaching more than 0.5 basal of tarsomere 5 or less, P. grouvellei, P. lupita, P. shepardi, P. smithi; not described for P. haitianus and P. argentinensis]; parameres truncate [not truncate in all others except P. smithi]. Similar male genitalia characteristics indicate that P. panamaensis may be closely related to P. smithi (cf. Figs. 7–10), although both species are clearly differentiable by the length of midlobe (penis) in relation to the parameres’ length, the type of antenna and the length of antennae and tarsomeres. However, for a better interpretation of the relationships among the species of Psephenops, a revision of the entire genus would be necessary. The comparisons mentioned here are based mainly on original descriptions and illustrations; the features of P. s m i t hi were taken from Deléve (1967) and Bameul (2001).

International audience; Aim. We tested the hypothesis that shredder detritivores, a key trophic guild in stream ecosystems, are more diverse at higher latitudes, which has important ecological implications in the face of potential biodiversity losses that are expected as a result of climate change. We also explored the dependence of local shredder diversity on the regional species pool across latitudes, and examined the influence of environ- mental factors on shredder diversity. Location: World-wide (156 sites from 17 regions located in all inhabited continents at latitudes ranging from 67° N to 41° S). Methods: We used linear regression to examine the latitudinal variation in shredder diversity at different spatial scales: alpha (a), gamma (g) and beta (b) diversity. We also explored the effect of g-diversity on a-diversity across latitudes with regression analysis, and the possible influence of local environmental factors on shredder diversity with simple correlations. Results: Alpha diversity increased with latitude, while g- and b-diversity showed no clear latitudinal pattern. Temperate sites showed a linear relationship between g- and a-diversity; in contrast, tropical sites showed evidence of local species saturation, which may explain why the latitudinal gradient in a-diversity is not accompanied by a gradient in g-diversity. Alpha diversity was related to several local habitat characteristics, but g- and b-diversity were not related to any of the environmental factors measured. Main conclusions: Our results indicate that global patterns of shredder diversity are complex and depend on spatial scale. However, we can draw several conclusions that have important ecological implications. Alpha diversity is limited at tropical sites by local factors, implying a higher risk of loss of key species or the whole shredder guild (the latter implying the loss of trophic diversity). Even if regional species pools are not particularly species poor in the tropics, colonization from adjacent sites may be limited. Moreover, many shredder species belong to cool-adapted taxa that may be close to their thermal maxima in the tropics, which makes them more vulnerable to climate warming. Our results suggest that tropical streams require specific scientific attention and conservation efforts to prevent loss of shredder biodiversity and serious alteration of ecosystem processes.
