description: <i>Xenovena</i> Marín &amp; Nakahara, genus novum. Type species <i>— Magneuptychia murrayae Brévignon, 2005</i>, by present designation. <b>Zoobank registration</b>: https://zoobank.org/Nomenclatural Acts/A165ADDA-88EC-4401-8DFD-D8B11C63F124 <b>Systematic placement and diagnosis</b>. The monotypic genus <i>Xenovena</i> <b>gen.n.</b> is a member of the so-called ‘ <i>Pareuptychia</i> clade’, and strongly supported as belonging to a clade including the genera <i>Pareuptychia</i>, <i>Euptychoides</i>, ‘ <i>Erichthodes</i> ’, <i>Neonympha</i>, <i>Megeuptychia</i> and <i>Satyrotaygetis</i> (Figure 9, SH-aLRT 100, UFB 98). <i>Xenovena</i> <b>gen.n.</b> is easily distinguished from all other known euptychiine taxa by its partially fused hindwing veins Rs and M 1, resulting in these two veins sharing the same origin, as shown in Figure 23a. Furthermore, both the forewing and hindwing of <i>Xenovena</i> <b>gen.n.</b> are somewhat elongated compared with many other euptychiine species (Figure 23). The female abdomen of <i>Xenovena</i> <b>gen.n.</b> possesses a patch of modified scales on both sides of the seventh abdominal segment (Figure 24f), in addition to the signa being absent (Figure 23h), both unusual features for the subtribe. In particular, the patch of modified scales apparently tightly attached to the abdomen at this location is not known in any other euptychiine species. The absence of signa is also a rare character state, although it is known to occur in a few euptychiine species (Nakahara, Llorente-Bousquets, et al., 2015). Phenotypically, <i>Xenovena</i> <b>gen.n.</b> resembles evolutionary distantly related taxa such as species in the genus <i>Hermeuptychia</i> Forster, 1964, but the aforementioned characters distinguish this taxon from any other externally similar euptychiine species. <b>Etymology</b>. The generic name <i>Xenovena</i> is a combination of the Greek word ‘xenos’ (meaning ‘strange’) combined with the Latin word ‘vena’ (meaning ‘vein’), in reference to the strange hindwing venation. The generic name should be regarded as a feminine noun in the nominative singular. <b>Description</b> (Figures 23 and 24). Some notable characters include: eyes setose; pterothoracic tibia with two principal longitudinal rows of spines ventrally, in addition to some spines dorsally, pair of spurs of similar length at distal end of tibia, first tarsomere with three principal longitudinal rows of spines ventrally until distal end, distal end of first tarsomere and remaining tarsomeres with four principal longitudinal rows of spines ventrally. Medium-sized Euptychiina (FW length typically 20 <i>–</i> 21 mm), male HW somewhat elongate, hindwing veins Rs and M 1 partially fused, thus sharing same origin and branching off close to wing margin. No strong sexual dimorphism in wing pattern: VFW with five submarginal ocelli in cells Rs, M 1, M 2, M 3 and Cu 1, otherwise wing pattern and shape as illustrated (Figure 23). Male with eighth tergite a narrow strip at basal side of eighth abdominal segment, broad weakly sclerotized patch absent, male 8th sternite present as two sclerotized patches; uncus and brachia short; costa rather reduced in lateral view; cornuti present, otherwise genitalia as illustrated (Figure 24). Female with abdomen bearing a patch of modified scales on either sides of seventh abdominal segment; intersegmental membrane of seventh and eighth abdominal segment pleated, folded but expandable, no visible weakly sclerotized region; lamella antevaginalis appearing as rounded, ‘thumb-like’ small plate apparently not fused with lateral plates of eighth abdominal segment, as illustrated (Figure 24); ductus bursae somewhat broad and membranous; corpus bursae small, signa absent. <i>Xenovena</i> Marín &amp; Nakahara, <b>gen.n.</b> <i>murrayae</i> (Brévignon, 2005), <b>comb.n.</b>, was <i>Magneuptychia</i> [Brévignon (2005, Lambillionea, 105(3)(1): 393-404)]
