( Figs. 6-10 View Figs )

Alloperla concolor Ricker, 1935:256 View in CoL .

Holotype ♂ (Royal Ontario Museum), Ontario, Dufferin Co., “E” Creek, headwaters of Pine River, Horning’s Mills

Material examined. Newfoundland: Rocky Brook, north of Deer Lake, Reidville Road, 8 June 1998, B.C. Kondratieff, R. W. Baumann, 56♂, 3♀, 5 larval skins from field associated adults, 1 pharate male larva ( CSU). Boot Brook , Hwy 1 jct Hwy 401, northeast of Deer Lake, 8 June 1998, B.C. Kondratieff, R . W. Baumann, 5 larvae ( CSU) .

Mature larva. Body length 9.0- 9.5 mm. General color brown without distinctive pattern. Head slightly paler forward of median ocellus ( Fig. 6 View Figs ). Anterior pronotal margin with about 11-15 moderately long setae at corners and posterior margin with 2 long and 2 short setae at corners ( Fig. 6 View Figs ). Mesonotal wingpads with ca. 12-16 outer marginal setae, metanotal wingpads with ca. 20 outer marginal setae beyond apex of mesonotal wingpad; inner marginal setae apparently absent ( Fig. 7 View Figs ). All legs with sparse ventral tibial fringes ( Fig. 9 View Figs ). Abdominal terga without mesal pale spots; posterior fringes on terga 8-9 with ca. 6 long thin setae and mixed shorter thick setae primarily located laterad to innermost long setae ( Fig. 8 View Figs ); mesal section of posterior fringe occupied by a few very thin setae. Abdominal intercalary setae restricted to lateral areas of segments. Cerci consisting of 15 apparent segments, vertical fringe developed on segments 10-15 ( Fig. 10 View Figs ); longest dorsal setae in segmental whorls of mid cercal segments about as long as segment.

Comments. The larva of this species was previously described by Fiance (1977) from Hubbard Book, New Hampshire specimens. Figure 2C View Figs of that publication shows a lateral view of the cercus with 18 apparent segments and the vertical fringe present on segments 12-18. Although this is at variance with our specimens, in all other respects our findings are in agreement.
