The genus Asthenopus has been distinguished by indicates in the following characters (Dom guez 1988): 1) ratio foreleg/FW male: 3/5?/5; 2) male foretarsus 2.5 times longer than foretibia; 3) foretarsal segment two related for the other people, and 2/3 the length of tibia); 4) ratio length of Rs stem/fork to margin 1/4 (or fork Rs at 2/10 from base to margin) ; 5) cubital intercalaries slightly diverging toward hind margin, ICu2 and ICu1 basally fused to CuA by cross veins; 6) ICu2 ending at anal margin or inside the tornus, 7) marginal intercalary veins get LOR-253 absent; 8) forceps ratio width/length: 1/7; eight) penes robust on basal 2/3; 9) MA fork base to margin 10/100; 11) IMP P1 not fused basally; 12) MP2-IMP equivalent in length, not fused; 13) foretarsal claws of male not so expanded distally (as in Asthenopodes). Coxae I and II directed ventrally, coxae III directed laterally. Abdomen. Gill I decreased in size, double, both portions subequal in length and width. Gills II II effectively developed, ventral portion smaller than dorsal portion; tergum X with properly developed ventral spine on posterior margin (not visible dorsally, Fig. 15E). Caudal filaments quick (curved in mature nymphs) with whorls of stout spines and basic setae at joinings. Distribution. Amazonas and Parana biogeographic subregions (Argentina, Bolivia, Brazil, Colombia, Ecuador, Peru). Discussion. The genus Asthenopus has been distinguished by suggests on the following characters (Dom guez 1988): 1) ratio foreleg/FW male: 3/5?/5; 2) male foretarsus two.five times longer than foretibia; three) foretarsal segment 2 equivalent for the other folks, and 2/3 the length of tibia); four) ratio length of Rs stem/fork to margin 1/4 (or fork Rs at 2/10 from base to margin) ; 5) cubital intercalaries slightly diverging toward hind margin, ICu2 and ICu1 basally fused to CuA by cross veins; six) ICu2 ending at anal margin or within the tornus, 7) marginal intercalary veins absent; 8) forceps ratio width/length: 1/7; 8) penes robust on basal 2/3; 9) MA fork base to margin 10/100; 11) IMP P1 not fused basally; 12) MP2-IMP equivalent in length, not fused; 13) foretarsal claws of male not so expanded distally (as in Asthenopodes). Our phylogenetic analyses only recovered a few of these character states as synapomorphies of this genus (see diagnosis and Appendix 2). The proposal of fnins.2013.00251 Dom guez (1988) and Hubbard Dom guez (1988) concerning the intermediacy of Priasthenopus gilliesi with respect to Asthenopus curtus and Asthenopodes picteti is in concordance with our results. Priasthenopus gilliesi resulted sister for the Povilla-Asthenopus clade, presenting some plesiomorphic character states shared with Asthenopodes.
