Oryphantes aliquantulus most resembles O. angulatus but can be distinguished from all members of the genus by the combination of the following characters: male palpal patella without conical tubercule ( Fig. 10 ); male palp paracymbium bearing a long and wide tooth at mid-point ( Fig. 10 ); lamella characteristica large, bifurcate apically ( Figs 10, 13 ); embolus with large serrated thumb ( Fig. 12 ). Female are diagnosed by the basal part of scape strongly constricted ( Fig. 14 ). Description. Male (n=5) : Total length: 1.60–1.70; carapace length: 0.67–0.70; carapace width: 0.57– 0.60; carapace light yellow-orange (1235M), finely reticulate, shiny. Sternum light yellow-orange (1235M), suffused with gray (warm gray 7M). Chelicerae light yellow-orange (1235M), promargin with 3 large teeth, retromargin with 4 denticles. Cheliceral stridulatory organ visible, with ~ 42 striae, narrowly spaced; associated stridulatory pick present at base of palpal femur. Abdomen uniformly colored, light beige (482M) to light gray (cool gray 3M) moderately covered with long semi-erected setae; book lung cover finely reticulate. Legs yellow-orange (1235M), leg formula 4123; tibia I–IV with two dorsal macrosetae; metatarsus I with dorsal trichobothrium (Tm I 0.15–0.17); Tm IV absent. Chaetotaxy: Fe I: 0-1-0-0, Fe II–IV: 0-0-0-0, Ti I: 2-1-1-0, Ti II: 2-0-1-0, Ti III–IV: 2-0-0-0, Mt I-IV: 1-0-0-0. Palpus length: 0.39–0.44. Palpal patella with large retrolateral macroseta ( Fig. 10 ); palpal tibia with two retrolateral trichobothia and a dorsal one ( Fig. 10 ); paracymbium (P) with long, wide tooth at mid-point ( Fig. 10 ); embolic division characterized by: large radix (R) ( Fig. 11 ); Fickert’s gland (FG) present in radix ( Fig. 11 ); lamella characteristica (LC) large, bifurcate apically ( Fig. 10 ), apex slightly variable ( Fig. 13 ); terminal apophysis (TA) large and serrate ( Fig. 11 ); embolus (E) with large serrated thumb (Th), embolus proper (EP) short ( Fig. 12 ). Female (n=5) : Total length: 1.60–1.80; carapace length: 0.64–0.70; carapace width: 0.54–0.57; overall coloration as in male. Chelicerae promargin with 3 teeth, smaller than male, retromargin with 4–5 denticles. Cheliceral stridulatory organ visible, with ~ 20 striae, widely spaced; associated stridulatory pick present at base of palpal femur. Abdomen as in male, book lung cover finely reticulate. Leg coloration as in male, leg formula 4123; tibia I–IV with two dorsal macrosetae; metatarsus I with dorsal trichobothrium (Tm I 0.16– 0.18); Tm IV absent; palpal tarsal claw present, reduced to a small triangular point. Chaetotaxy as in male. Epigynum width: 0.25–0.30. Epigynum lateral wall (LW) with elongated outgrowth, parallel to scape ( Fig. 14 ); scape (Sc) folded; proximal part of scape basally narrowed, enlarging considerably ( 3x ) ( Figs 14, 15 ), ventral part bearing a scapus bag (SB) ( Fig. 18 ); distal part of scape with short stretcher (St) ( Figs 16, 17 ); spermathecae (S) oblong and bent ( Fig. 18 ). Distribution. U.S.A. : Maine; Canada : Québec to Alberta ( Fig. 20 ). Habitat. Forest litter, mainly conifers, and sphagnum. Etymology. The epithet aliquantulus means little or small in latin and refers to the small size of the species for a linyphiine.
