03C5181CFFA22976FEE1F9DAFCE86290.taxon	etymology	Etymology. We dedicate this species to the late Professor Dr. C. F. Wu in recognition of his enormous contribution to the knowledge of Chinese Plecoptera.	en	Stark, Bill P., Sivec, Ignac (2009): Sweltsa Wui And Haploperla Valentinae (Plecoptera: Chloroperlidae), Two New Stoneflies From Sichuan Province, China.

03C5181CFFA22976FEE1F9DAFCE86290.taxon	diagnosis	Diagnosis. This species is similar in pronotal pigment pattern to Sweltsa insularis (Zhiltzova & Levanidova 1978), S. nikkoensis (Okamoto) (Ham 2008), and also to the Japanese species S. abdominalis (Okamoto) and S. sapporoensis (Okamoto), however the general shape and setal pattern of the epiproct is different among these species [except S. sapporensis (Figs. 22 - 24) and S. nikkoensis (Figs. 25 - 27) which are quite similar]. Sweltsa wui is the only known Asian species in which the epiproct apex is as wide as, or wider than, the base (Figs. 5 - 6). The species of genus Sweltsa are quite variable in epiproct structure and several species complexes in the group may at some time be given generic rank. The structure of tergum 9 in S. wui suggests it could be placed in another genus. A few, unrelated Nearctic species are also known to lack the transverse process (Kondratieff & Baumann 2009), but these species have the posterior margin of tergum 9 strongly concave as in other Nearctic members of the genus. Our study of Asian Sweltsa indicates two Japanese species, S. abdominalis (Figs. 19 - 21) and S. sapporoensis (Figs. 22 - 24) share the tergum 9 modifications with Nearctic members of the group but also share a similar color pattern with S. wui. In addition, S. insularis, a similarly pigmented Russian species, also lacks the tergal 9 modification (Figs. 28 - 30), but S. colorata (= S. nikkoensis), another Russian species with similar pigment, has a well developed process on tergum 9 (Figs. 25 - 27). Consequently, in the absence of data from other life stages, we are tentatively placing the new species in genus Sweltsa.	en	Stark, Bill P., Sivec, Ignac (2009): Sweltsa Wui And Haploperla Valentinae (Plecoptera: Chloroperlidae), Two New Stoneflies From Sichuan Province, China.

03C5181CFFA52976FEDDFC26FB146297.taxon	description	Adult habitus. General color pale yellow patterned with pale brown. Pronotum bearing an obscure pale brown, median band, meso and metanotae dark brown U-patterns with a strong mesal prong (Figs. 11, 14). Abdomen with a median longitudinal brown band from segments 1 - 8, but terga 1 and 8 with brown areas reduced to small anterior spots; brown areas on terga 2 - 7 cover most of tergal length but include a pair of small, circular pale areas on each segmental band. Legs and wings pale. Male. Forewing length 6 mm. Tergum 9 without posterior lobe, but bearing a mesal patch of short, thick setae (Fig. 12). Epiproct short, length ca. 186 µm and about as wide as long (Figs. 9, 12); outline subtriangular with rounded margin in dorsal aspect; margin strongly sclerotized but posterodorsal area membranous and clothed with sparse patch of short, brown setae (Figs. 9 - 10, 13, 17). Female. Forewing length 7 mm. Subgenital plate slightly produced as a small rounded lobe clothed with long setae (Fig. 15). Intersegmental area posterior to sternum 9 bearing a large median microtrichia patch. Larva. Body length ca. 7 mm. General color brown, pattern questionable due to pharate adult features. Pronotum bearing well developed setal rows on anterior and posterior margins, but interrupted on lateral margins leaving a large gap (Fig. 16). Cerci with ca. 12 segments; each segment with prominent dorsal and ventral seta in lateral aspect (Fig. 18).	en	Stark, Bill P., Sivec, Ignac (2009): Sweltsa Wui And Haploperla Valentinae (Plecoptera: Chloroperlidae), Two New Stoneflies From Sichuan Province, China.

Haploperla lepnevae and H. ussurica, the two species reported from China, both have triangular epiprocts with narrow tips (Zhiltzova & Zwick 1971) and H. zwicki Stark & Sivec, known from Thailand, has a much more distinctly pigmented pronotal disk than the new species.	en	Stark, Bill P., Sivec, Ignac (2009): Sweltsa Wui And Haploperla Valentinae (Plecoptera: Chloroperlidae), Two New Stoneflies From Sichuan Province, China.
