SUGENUS Ecplectica (The bees of the World by Michener 2007)

MALES

Clypeus usually not protruding in front of eye by as much as half of eye width, as seen in side view, or if protruding by half of eye width or more, then mionimum length of first flagellar segment one-third or more of maximum length of second segment
terga often not fringes by apical pubscent bands
bands when present interrupted medially and/or preapical
clypeus usually protuding one-half or less of width of eye, as seen in side view, or if protruding more, then maximum length of first flagellar segment less than 0.4 of maximum length of second segment
Maximum length of first flagella segment less than maximum length of second segment and distinctly less than that of third.
clypeus usually pale, ocasionally partly or wholly black
minimum length of first flagellar segment half of maximum length of second segment or less
T2 to T5 with pale pubescent bands usually not all apical or not subequal in width, often interrupted medially and usually subapical
median apical lobes of S7 thin, hyaline with short to moderately long hairs on ventral surfaces, not curles ventrally, relatively large
gonostylus often less than half as long as gonocoxite in lateral view at least twice as broad near base as near apex, narrowing abruptly near middle, not capitate
median lobes of S7 relatively small with several short hairs ventrally

FEMALE

scopal hairs branched, usually abundantly so, but if weakly branched, then clypeus in profile not protruding in front of eye by as much as two thirds width of eye, as seen in lateral view.
clypeus protruding in front of eye by less than half width of eye, as seen in lateral view, or if protruding by as much as half width of eye, then inner orbits distinctly converging below and/or inner surface of hind basitarsus with hairs bright red to yellow
scopal hairs strongly branched and hiding outer surfaces of hind basitarsus or, if weak, and with few branches, then terga coarsely punctate at least basally, or moderately shiny to shiny and strongly banded with abundance pubscence, or pygidial plate narrowly U-shaped
T2 to T4 with distal pale pubscent bands (at least on T2) not reaching apices of terga, or if reaching apices of terga, then diffuse over entire tergum or much wider than basal area of dark pubescence or of varying width across each tergum or between terga
