(2019): A Review Of The Genus Bolshecapnia Ricker, 1965 (Plecoptera: Capniidae), And Recognition Of Two New Nearctic Capniid Genera. Illiesia 15 (1): 1-26, DOI: http://doi.org/10.5281/zenodo.4761256
03C787A8FFA4FFCFFC13FBD70EFDF961.taxon	description	Male characteristics: 1. Epiprocts are relatively wide, tongue-shaped structures that bear a pair of sclerotized, acute lateral hooks (Figs. 1 - 2, 7, 28). 2. Patches of spongy-appearing tissue occur dorsoapically along the lateral margins of the epiproct (Fig. 12). 3. A relatively wide and long median dorsal groove is present on the epiproct (Figs. 7 - 8). 4. A well developed, hairy vesicle arises from the intersegmental membrane between the 8 th and 9 th abdominal sterna (Figs. 22, 32). 5. Tergum 9 modified with patches of short, thick setae, or with thimble, or cone-shaped dorsal knobs (Figs. 2, 9 - 10, 27 - 28). Female characteristics: 1. Subgenital plates project slightly beyond the posterior margin of sternum 8, often reaching to, or beyond the sclerotized base of sternum 9 (Figs. 5 - 6, 33 - 34). 2. Subgenital plate usually sclerotized, but rather uniformly, without a distinctive pattern of pale and dark pigment. Wings: 1. Most known specimens of Bolshecapnia are macropterous, but at least some individual males of the Iceberg Lake, Montana population of B. spenceri have wings that reach about mid-length of the abdomen and some females of that population have wings that reach almost to the abdominal tip. 2. The R 1 forewing vein is correctly described as “ curved upward at origin ” by Baumann et al. (1977) in their generic key, however their fig. 295, which purportedly illustrates this character, shows a straight, but anteriorly slanted R 1 vein. The same language is used by Stewart & Oswood (2006) in their generic key to regional capniid genera. Their (fig. 3.7), illustrates this character correctly as an anterior curvature of the R 1 vein beyond its junction with Rs. The wording of this character and figure used to illustrate it are also in agreement in Stewart & Stark (2008), however the degree of cephalad curvature of the R 1 vein in Bolshecapnia is slightly less than that shown in species of Mesocapnia Raušer, 1968, by Stewart & Stark (2008). Larval characteristics: Only one Bolshecapnia species, B. spenceri, has been described in the larval phase (Stewart & Stark 1988, 2002, Stewart & Oswood 2006). A key to larvae of the genus is included in Stewart & Stark (1988, 2002, 2008) and in Stewart & Oswood 2006). 1. The cerci of B. spenceri have more than 18 segments and each has an apical whorl of a few moderately long setae, and a few (1 - 3) short intercalary setae along the outer and inner margins of each cercal segment (Stewart & Oswood 2006). 2. A relatively wide, almost rectangular area is enclosed within the Yarms and the anterior transverse ridge of the mesosternum (Stewart & Oswood 2006).

03C787A8FFA3FFC2FED6F9230E10F8DD.taxon	description	Male epiproct (n = 3). Length 544 - 593 μm, width at midlength 185 - 213 μm, greatest width near base 147 - 253 μm. A pair of curved, acute, sclerotized hooks arise from either side of the median groove at about half the distance between the epiproct apex and the base of the spongy area from either side of the median groove. The hooks extend slightly beyond lateral margins of the epiproct body (Figs. 1 - 3), and their tips reach to about 0.8 of the epiproct length. Median groove wide near apex and narrowed near dorsobasal knobs (Fig. 4). Median groove divides a pair of spongy-appearing clumps of tissue near hooks (Fig. 2). Apex without a protruding membranous process; dorsobasal humps low, smooth and not outlined by a prominent posterodorsal ridge (Fig. 2 - 3). Paraprocts with a hairy, plate-like basal area and slender apices. Tergal process (n = 3). Absent, but tergum 9 bears a median patch of short, thick setae (Fig. 1) and lacks a median anterior notch. However, tergum 10 bears a median anterior notch filled with membranous tissues projecting into the notch from tergum 9 (Fig. 7). Vesicle (n = 1). Length 305 μm, width at midlength 311 μm, basal stalk short and 168 μm wide. Surface entirely covered with thick setae except for the short stalk that extends under the basal roll of tissue (Fig. 4). Female subgenital plate (n = 2). This structure is a triangular plate that extends beyond the anterior margin of sternum 9 (see fig. 10 in Ricker 1965, fig. 173 in Baumann et al. 1977, and fig. 3.12 in Stewart & Oswood 2006). The images we present show an almost triangular plate, rounded and glabrous at the apex with convergent lateral margins (Figs. 5 - 6). The transverse striations observed on the subgenital plate in Fig. 6 may be an artifact of dehydration. Larva. Unknown.	en	Broome, Hannah Jean, Stark, Bill P., Baumann, Richard W.

03C787A8FFA3FFC2FED6F9230E10F8DD.taxon	discussion	Comments. The figures and descriptions of the male of this species by Ricker (1965) and Stewart & Oswood (2006), and our SEM figures indicate that it is related to B. milami and B. spenceri. Ricker (1965) states the species “ … is closely related to C. spenceri … ”. The two species are thought to be allopatric in British Columbia with the western limit of B. spenceri extending into the Selkirk Mountains and the eastern limit of B. gregsoni extending to the Valhalla range (Ricker 1965). According to Ricker (1965) the major distinction between B. gregsoni and B. spenceri males is the presence of a “ deep groove ” that extends posteriorly from the midpoint of tergum 9 in males of the latter; females of B. spenceri have a very narrow, and often asymmetrical, subgenital plate (figs. 15 - 16 in Ricker 1965). Males of these species each have epiprocts with a pair of sharply pointed, sclerotized hooks near midlength and conspicuous, spongy-appearing dorsal patches of anterolateral tissue (Figs. 3, 9, 21, 28), consequently these two capniid species have the distinction of being relatively easy to distinguish as females and somewhat more difficult to distinguish as males. The epiprocts of B. milami differ from the other two species in having a downturned mesoapical hook. The original material of B. gregsoni reported by Ricker (1965) includes 21 ♂ and 30 ♀ specimens; most of these were collected from Vancouver Island at “ … sites at or near high mountain lakes ” (Ricker 1965).	en	Broome, Hannah Jean, Stark, Bill P., Baumann, Richard W.

03C787A8FFACFFC7FC5FFB720B37FC74.taxon	description	Male epiproct (n = 6). Length 524 - 543 μm, width at midlength 224 - 250 μm, greatest width near base 295 - 300 μm. Sclerotized hooks arise subapically from either side of the median groove, and are bent sharply laterad, and extend beyond the lateral margins of the epiproct body (Figs. 25 - 29); tips of basolateral hooks extend forward for about 0.75 of the total epiproct length. Median groove wide near apex, narrowing gradually to the widest point near the epiproct base (Fig. 26). Small clumps of spongy appearing tissue located along lateral margins near base of hooks (Figs. 27 - 28). Base of epiproct body bearing a pair of dorsal ridges separated by terminus of median groove (Figs. 27, 29). Apex with a protruding membranous process (Figs. 29 - 30). Tergal process (n = 3). Absent, but tergum 9 covered with a broad band of short, thick setae (Figs. 27 - 28). Vesicle (n = 1). Length = 219 μm, basal width =. 214 μm, median width = 252 μm. Process relatively wide, slightly wider near midlength (Fig. 31 - 32). Ventral surface covered with thick setae. Female subgenital plate (n = 3). This structure is an apically narrowed, tongue-shaped process, about twice as wide at midlength as near the apical margin (Figs. 33 - 34); the structure extends beyond the anterior margin of sternum 9 (see fig. 169 in Baumann et al. 1977), and is hairless except for a few scattered long setae on the basal half. Several variations in the structure are shown in figs. 15 - 16 (Ricker 1965). Larva. Described by Stewart & Stark (1988, 2002) and Stewart & Oswood (2006). The larval characteristics listed above for the genus are based on these descriptions.	en	Broome, Hannah Jean, Stark, Bill P., Baumann, Richard W.

03C787A8FFA9FFC5FF3CFC4F0A53FD28.taxon	description	Male characteristics: 1. The male epiproct is almost uniformly slender from base to apex except for an apical area capable of being folded laterally to increase the apical width (Figs. 37, 40 - 42). 2. The ventral and lateral margins of the finger-like epiproct are formed by a pair of thick sclerites that are separated along the dorsum by a wide groove (Figs. 37 - 40); width of the groove varies based on position of the sclerites (compare Figs. 51 - 52). 3. Abdominal tergum 9 bears a pair of conical knobs separated by a gap slightly wider than the folded epiproct tip (Figs. 37 - 38, 40, 43, 45). 4. The ventral vesicle is almost circular in outline and is attached to the intersegmental membrane between sterna 8 and 9 (Figs. 47 - 48). The vesicle surface is covered with thick setae. Female characteristics: 1. The subgenital plate is uniformly pigmented and extends across the entire width of sternum 8 between the two pleural membranes (Figs. 35 - 36). 2. The posterior margin of the plate is rounded and scarcely exceeds the posterior margin of sternum 8. Wings: 1. The venation of E. maculata, the only known species, is very similar to that of Bolshecapnia and Sasquacapnia, however the wings of Eurekapnia have scattered brown maculations that give them a distinctive appearance.

03C787A8FFB3FFDFFF3BFE860B66FE58.taxon	description	Male epiproct (n = 3). Length 718 μm, width at midlength about 147 μm, width near base 158 μm, greatest width 194 μm, subapical width at narrowest point 70 μm. Epiproct body broad basally and narrowed gradually to subapical bottleneck (Figs. 67, 70 - 71) in dorsal and lateral aspect; apex bearing complexly lobed membranous tissue above a well formed ventral lip (Figs. 69, 71). Median groove well developed, with a pair of parallel ridges extending subapically to near base of dorsobasal sclerites (Figs. 67, 70). Dorsobasal sclerites short, broad and apically pointed (Figs. 68, 72). Tergal process (n = 2). A pair of hairy, low rounded hump-like structures located on tergum 9 (Figs. 67, 71). Vesicle (n = 3). Similar to S. missiona but slightly more rounded in ventral aspect. Female subgenital plate (n = 1). Correctly associated and illustrated in figs. 13 - 14, by Baumann & Potter (2007). Ricker’s earlier figure for this structure is now attributed to S. missiona (Baumann & Potter 2007). The posterior margin of the plate is truncate and scarcely projects beyond the posterior margin of sternum 8. Larva. Unknown.	en	Broome, Hannah Jean, Stark, Bill P., Baumann, Richard W.
