Each valve consisting of roundish or oval pieces of liverwort. Food and feeding behavior (Fig. 5 J). Larvae eat leaves of the liverwort, Scapania uliginosa (Sw. ex Lindenb.) Dumort. (Jungermannidales, Scapaniaceae). They pierce cell walls and swallow contents of cells one at a time. Emergence (Fig. 2 E). Emergence was observed in the laboratory (Corvallis, Oregon,) in late July, 2009. Teneral adults emerged on leaves of liverwort in the morning (5: 30 – 9: 30 AM). The newly emerged adults stretch their wings and abdomens in an upright position like mayflies, which takes ca. 3 minutes (n = 2). Annual life cycle (Fig. 6). Occurrence of 5 development stages in British Columbia (B); Washington (W); Mary’s Peak, Benton County, Oregon (M); other sites of Oregon (O); and California (C) were summarized in 10 - day periods based on the collecting data in “ habitat and biology ” and Table 1 in Fig. 6. Collection records that did not specify early or final instar larvae were omitted from the figure. Eggs and early instar larvae were found mainly in late July and September – early November, respectively. Final instar larvae were seen from September to the following July. Adults occurred mainly in June to September. Therefore, a univoltine life cycle with a summer emergence season was suggested as shown by the grey band in Fig. 6. However, another annual cycle could be supposed for a few populations, because some adults and early instar larvae were collected in April – May and June, respectively. Habitat and biology. The larvae live in springs, spring brooks and seepage areas of forested mountain streams, often just above the water surface and in hygropetric habitats, and they are exclusively associated with moss and liverwort. Observation at Mary’s Peak, Benton County, Oregon. Many springs and seeps enter the stream around 1100 – 1200 m elevation where the channel is 1 – 2 m wide; moss and the liverwort Scapania ulinosa are abundant; cold year-round water regime. Many larvae and pupae of P. nearcticus were found in the liverwort and moss on cobbles and logs mainly just above water. Specimens were collected and deposited by RWW unless otherwise indicated: 21 August 1952, V. Roth, 1 male; 03 September 1982, many 5 th and early instar larvae; 20 September 1981, 22 1 st – 4 th instar larvae; 31 October 1981, 26 empty pupal cases, no larvae found; 30 May 1982, many 5 th - instar larvae; 03 November 1982, 1 st to 4 th- - instar larvae and many 5 th - instar larvae with newly constructed cases; 27 April 1983, 15 5 th - instar larvae; 09 August 1983, about 60 adults; 29 July 2009, 2 males, 2 females, 10 pupae, 2 5 th - instar larvae, 5 eggs, RWW & TI (TI); 07 July 2010, no larvae or adults; 01 August 2010, 4 males, many adults seen.

(2014): The genus Palaeagapetus Ulmer (Trichoptera, Hydroptilidae, Ptilocolepinae) in North America. Zootaxa 3794 (2): 201-221, DOI: http://dx.doi.org/10.11646/zootaxa.3794.2.1
03D66A02FF88C86730C9006EFE2492F2.taxon	discussion	Remarks. The male of this species is characterized by tri-branched lateral appendages of tergite IX, which are never seen in other congeneric species. On the other hand, the female, pupa, final instar larva, early instar larva, egg and case are very similar to those of other congeneric species, including Nearctic P. celsus (Ulmer 1912; Ross 1938; Flint 1962; Ito & Hattori 1986; Botosaneanu & Levanidova 1987; Ito 1991 a, 1991 b, 1997, 1998, 2010; Ito et al. 1997). The habitat, feeding behavior and emergence behavior of this species are also very similar to those of other species studied (Ito 1998; Ito & Vshivkova 1999). The female pupal weights, used for an indicator of fecundity in the subfamily Ptilocolepinae (Ito 1998), were 1.43 – 2.00 mg (n = 4, average 1.73 mg), suggesting P. nearcticus resembles P. parvus in terms of fecundity (Ito 1998). The liverwort used for food and case materials by P. nearcticus is Scapania uliginosa (Sw. ex Lindenb.) Dumort., which is the first report of this host for a Palaeagapetus species. Another congeneric liverwort host, Scapania undulata (L.) Dumort., was reported for a population of Japanese species, P. parvus (Ito 1991 a). Life cycles have been studied for five Far East Asian species; three of them, P. flexus, P. parvus and P. kyushuensis, are distinctly univoltine with a short summer emergence period (Ito 1991 b, 1998; Ito et al. 1997), and the fourth species, P. finisorientis, has 3 – 4 generations in 2 years with a long flight period from March – October (Ito & Vshivkova 1999). For the fifth species, P. ovatus, two sorts of life cycles have been reported: 3 – 4 generations in 2 years with a long emergence period (from March to October) at many sites (Ito 1988, 1998; Kuhara 2011), but univoltine with a short summer flight period in a very cool headwater stream at high elevation (Kuhara 2011). According to the collecting data (Fig. 6), the annual cycle of P. nearcticus may be 1 generation per year at many sites, but with a more complicated life cycle and long emergence period at a few sites (similar to P. ovatus), and probably depending on local water temperature regimes.	en	Ito, Tomiko, Wisseman, Robert W., Morse, John C., Colbo, Murray H., Weaver Iii, John S.

03D66A02FF88C86730C9006EFE2492F2.taxon	distribution	Distribution and specimens (Fig. 8). The species has been reported from the following states and provinces: CANADA: British Columbia (Williams & Williams 1987; and as P. guppyi by Schmid 1951; Schmid & Guppy 1952; Blickle 1979), USA: Washington (Banks 1936; Ross 1944; Blickle 1979; Ruiter et al. 2005), Oregon (Anderson & Wold 1972; Anderson 1976; Blickle 1979; and as P. guppyi by Anderson 1976; Blickle 1979), and California (Denning 1956; Blickle 1979). The species is patchily distributed in mountain ranges along the western coast of North America from British Columbia (about 100 – 200 km north of the U. S. – Canadian border), southward in the Cascade and Sierra Nevada Mountains to Sequoia National Park in the southern Sierras; and southward in the Olympic Mountains and coastal ranges of Oregon and California to Mendocino County (Table 1). Most of the Cascade Mountain sites are on the wetter west slopes, though it has been found at several sites on the more xeric east slope of the Cascades. The majority of the springs and spring-streams where it occurs are in mature or old-growth coniferous forests. In the Cascade and Coastal Mountains in the northern part of its range, it is generally found at elevations <1200 m, below the alpine and subalpine zone. In The Sierra Nevada Mountains in the southern part of its range, it has been found in coniferous forests between 1265 – 2134 m elevation. TABLE 1.

The larvae of this species also live in springs, spring brooks and seepage areas of forested mountain streams and exclusively associated with moss and liverwort. Observation at Maul Spring, Westmoreland County, Pennsylvania (1) Population. A high population was observed at Maul Spring, Powdermill Nature Reserve of the Carnegie Museum of Pittsburgh, near the town of Rector, Westmoreland County (Weaver 1974). The origin (eucrenon) of Maul Spring is a sandy-bottom pool (about 12 m in diameter). Adults were collected from April to November, 1974, inclusively. The water temperature of the spring is relatively constant, ranging from 8 ° C in the winter to 10 ° C in the summer. This mild temperature regime supported an abundant growth of aquatic bryophytes which consequently supported aquatic herbivores, including P. celsus Ross and Adicrophleps hitchcocki Flint (Brachycentridae). Three benthic samples were collected each month from January to August of 1974, inclusively, in the riffle area of the springbrook (hypocrenon, about 12 m wide) just below the source of the spring, using a Modified Hess sampler (Merritt et al. 2008, fig 3.6). The number and density of P. celsus larvae collected each month are depicted in the followings: January (65 larvae collected, larval density 233.2 / m 2), February (24 larvae, 86.1 / m 2), March (27 larvae, 96.9 / m 2), April (23 larvae, 82.5 / m 2), May (4 larvae, 14.4 / m 2), June (6 larvae, 21.5 / m 2), July (4 larvae, 14.4 / m 2), August (35 larvae, 125.6 / m 2). The number and density of larvae were highest in January, lower in February, March and April, lowest in May, June and July, and then increased in August. The decline in numbers and density between January and February correlated with the phenology of the dominate aquatic liverwort in the springbrook, tentatively identified as Chiloscyphus pallescens (Ehrh. Ex Hoffm.) Dum. JSW observed that the liverwort was abundant and green in January, but in February less abundant and its leaves and stems had turned brown, including that sporulation had occurred. (2) Living Larvae. While examining live larvae under the microscope, JSW observed that the lateral processes of abdominal segments I – VIII do not resemble truncated fleshly tubercles of dead specimens as described by Flint (1962), but are actually much larger, membranous spheres. JSW also observed when a larva was prodded, to force it to exit its case, that the individual would sometimes turn 180 ° while staying completely inside its case. Then its head and thorax would emerge from the other end of its case and the larva would proceed to craw away in the opposite direction (in respect to its previous position). The larva had the ability to use either end of its case as an opening for its head and thoracic legs, and the two ends of the case seemed to be rather similar in structure and function, similar in these ways to the larval behavior and case structure of distantly related Glossosoma spp. (Glossosomatidae) and Setodes spp. (Leptoceridae) (Wiggins 1996). Could it be that the “ anterior ” and “ posterior ” ends of the larval case are only relative to the current orientation of the occupant? (3) Habitat of larvae. At Maul Spring there were massive amounts of aquatic mosses and leafy liverworts attached to rocks in the brook. In the winter the greenery of the springbrook made a striking contrast to the surrounding brown dead leaves and white snow. The aquatic mosses dominated in the higher areas of the rocks that were often exposed above the surface of the water and the leafy liverworts were more common in the lower areas that were usually submerged and covered by water; the larvae of P. celsus were usually found among the liverworts. JSW hypothesizes that the mosses flourished on the tops of the stones because they were well protected from erosional forces and ice accumulations that were minimized at Maul Spring, allowing them to flourish on the tops of the rocks. The leafy liverworts on the other hand, appeared to be more opportunistic in occupying lower areas where the mosses could not maintain their dominance. At other locations, this might explain why the larvae occur in marginal lotic erosional areas, sprawling above the water where the leafy liverworts can flourish. Perhaps the adaptation of lateral abdominal spheres of the abdomen of Palaeagapetus evolved so that the larvae could become better sprawlers - a mode of locomotion well suited to marginal lotic microhabitats.	en	Ito, Tomiko, Wisseman, Robert W., Morse, John C., Colbo, Murray H., Weaver Iii, John S.

03D66A02FF83C87C30C90651FA1193CA.taxon	discussion	Remarks. The male of this species is distinguished by the branched lateral appendages of segment IX from other congeneric species. On the other hand, the female, pupa, final instar larva and case are very similar to those of other congeneric species including the other Nearctic species, P. nearcticus (Ulmer 1912; Ross 1938; Ito & Hattori 1986; Botosaneanu & Levanidova 1987; Ito 1991 a, 1991 b, 2010; Ito et al. 1997; Ito & Vshivkova 1999). The liverwort used for food and case materials was tentatively identified as Scapania nemorosa (L.) Dum. The life cycle of this species has also been studied (Flint 1962).	en	Ito, Tomiko, Wisseman, Robert W., Morse, John C., Colbo, Murray H., Weaver Iii, John S.

This species has been reported from Quebec and New Brunswick south to Oklahoma, Tennessee, and North Carolina (Table 2), including the following states and provinces: CANADA: New Brunswick (Harris & Lawrence 1978); Quebec (Roy & Harper 1975, 1979; Wiggins 1977, 1996; Blickle 1979; Williams & Williams 1987).

The new material from Newfoundland represents a new record of P. celsus from that Canadian province and the northernmost record for the species. In addition, students of JCM have studied a population of this species in South Carolina (Oconee County, unnamed tributary of Wash Branch, 16 km NW of Walhalla, 34.9144 ° N, 083.1071 ° W, 664 m). JCM confirmed the identity of these students’ specimens, but no voucher specimens are in the Clemson University Arthropod Collection. We have been unable to find specimens of the species at this locality in recent years, suggesting that this southernmost population may no longer exist, possibly as a result of climate change as the ranges of cool-adapted species shift northward (Sheldon 2012; Comte & Grenouillet 2013).
