Notes
Locality where specimen was collected in Canada - British Columbia
Flight Season - Month - April
Body length, in mm - 13
Head, labral process, margin - Entire, edge continuous from side to side
Head, vertex height, distance from lateral ocelli to rear margin of head - About 1 ocellar diameter
Head, facial fovea, width at level of antennal sockets - or at bottom for species with short fovea - BROAD, fovea broader than antennal socket
Head, clypeus, surface texture between pits - SHINY in center or apically and DULLED at least along dorsal and lateral margins
Head, facial fovea, length - Extremely long, reaching to below level of top margin of clypeus
Head, facial fovea, minimum distance to lateral ocellus - ABOUT ONE ocellar diameter
Thorax, propodeal triangle, percentage of LENGTH coarsely sculptured
5 - 50 percent
Wings, forewing, number of submarginal cells - 3
Wing, forewing, vein m-cu meets second submarginal cell - At middle of cell

Notes from Discover Life key
Flight Season - Month = April
Locality where specimen was collected in Canada = British Columbia
Body length, in mm = 10
Head

• malar area, minimum length = Extremely short, no wider than rim of compound eye
• clypeus, surface texture between pits = SHINY throughout
• labral process, length = Moderate, between one-third and one-half length of labrum
• facial fovea, color of hair = All pale, white to yellow
• facial fovea, length = Long, reaching to below level of lower margin of antennal socket, sometimes to level of top margin of clypeus
• facial quadrangle - Note, the diagram is misleading the measurement is from the bottom of the middle ocellus = QUADRATE, about as broad as long
• labral process, margin = Bidentate
• vertex height, distance from lateral ocelli to rear margin of head = About 1 ocellar diameter

Thorax

• pronotum, ridge extending down from humeral angle (?Absent, no trace of ridge present)
• Pronotum, Humeral Angle (? ABSENT, rear margin of pronotum smoothly rounded)
• propodeal triangle, percentage of LENGTH coarsely sculptured = 5 - 50 percent
• propodeal corbicula, form = Incomplete, without anterior fringe of hairs, internal hairs usually present
• scutum, form of hair = Short medially, half as long as hairs on mesepisternum, but not mat-like
• scutum, texture = Dulled throughout, tessellate
• scutum, pitting between parapsidal lines, except midline area = Separated by 1-3 pit widths

Wings

• forewing, number of submarginal cells = 3
• forewing, vein m-cu meets second submarginal cell = At middle of cell

Abdomen

• Tergum 2, Surface texture in middle of tergum = GRANULAR or with fine lines, usually dull but may still be somewhat shiny
• Tergum 2, Pale apical hair bands = Narrowly interrupted medially, no more than half of apical margin bare
• Tergum 2, pitting spacing on longitudinal center of segment - - Note, ignore pitting patterns along the rim and the very base of the segment = Absent or indistinct and difficult to see even at high magnification
• pygidial plate, internal triangle or ridge = Present, with median raised or textured triangle or longitudinal ridge
• colour of integument = All DARK, black to reddish-brown, without distinct red or orange coloration or metallic reflections

Legs

• rear legs, tibial scopal hair formation = Hairs simple and unbranched IN CENTER of outside face of tibia, but hairs along outer edges of tibia can be branched or unbranched
