  • Female T1–T2 punctationpunctation:
    overall pattern of the punctures on a surface of a bee, includes size of punctures and the distance between them
    coarse, as large or larger than punctationpunctation:
    overall pattern of the punctures on a surface of a bee, includes size of punctures and the distance between them
    on scutumscutum:
    the large segment on top of the thorax located between the wings and behind the head
    , with shiny interspaces.

  • Male gonostylusgonostylus:
    the apical-most appendage of the male genitalia, which is usually quite hairy
    approximately 1.5x wider at widest point than at the base. Notch at the apexapex:
    end of any structure
    deeper than wide.

  • Male S3S3:
    the plates on the underside of the abdomen, often abbreviated when referring to a specific segment to S1, S2, S3, S4, S5, S6, S7, or S8
    premarginal brush with unhooked hairs at the tips.

  • Male S3S3:
    the plates on the underside of the abdomen, often abbreviated when referring to a specific segment to S1, S2, S3, S4, S5, S6, S7, or S8
    with shiny hairless zone rounded and raised, not extending along midline.

  • Male laterallateral:
    relating, pertaining, or attached to the side
    combs on S5S5:
    the plates on the underside of the abdomen, often abbreviated when referring to a specific segment to S1, S2, S3, S4, S5, S6, S7, or S8
    small, with the apexapex:
    end of any structure
    no wider than the arm proceeding it. 

  • Male third coxacoxa:
    the basal segment of the leg
    with produced, flattened, round tooth at apexapex:
    end of any structure
    .

  • Male third trochantertrochanter:
    segment of the insect leg between the coxa and the femur
    hairs dense and even length but not velvety.

May be confused with

Male Pseudoanthidium cribratum can be distinguished from all similar other similar species by the produced, flattened lobe on the apexapex:
end of any structure
of the third coxacoxa:
the basal segment of the leg
. Female P. canariense are most similar to P. rozeni but they can be distinguished by the coarser punctationpunctation:
overall pattern of the punctures on a surface of a bee, includes size of punctures and the distance between them
on T2T2:
the segments on the top side of the abdomen, often abbreviated when referring to a specific segment to T1, T2, T3, T4, T5, T6, or T7
with shagreened interspaces.

Nesting behavior

Little is known about the nesting biology of Pseudoanthidium cribratum but most species of Pseudoanthidium nest in pre-existing cavities like in wood, stems, galls or crevices (Litman et al. 2021Litman et al. 2021:
