Explanation of Names

trifasciata = 'Three-banded', Adjective - This is probably derived from the Latin tri (three) + fasciata (banded)(Inflection of fasciātus). This refers to the three yellow abdominal bands on the females of this species.

Numbers

2 sspp., both found in our area:(1)

1. Dielis trifasciata nassauensis: FL (Key Vaca); Bahamas

2. Dielis trifasciata trifasciata: FL; Greater Antilles

Identification

The females are separated from other members of the genus in Florida in that they have only three abdominal bands. The pronotum has a strong fringe of pale rather than brown setae.

♀

The males have four bands on the abdomen, much like other members of the genus. The yellow markings are a deeper yellow than in males of the other eastern species, D. plumipes and D. dorsata. The strong and extensive yellow on the legs and on the clypeus further distinguish D. trifasciata males.(2)

♂

Range

FL;(3) Greater Antilles and Bahamas(2)

See Also

The more widespread species, Dielis plumipes have lighter, white-to-ivory colored abdominal bands (not as yellow). The females of D. plumipes usually have four abdominal bands and orange-colored hairs behind the head. Males of D. plumipes have an entirely black clypeus.(2)

Males of D. dorsata are very similar to those of D. plumipes and have more white-to-ivory markings. They also have the margins of the clypeus marked with yellowish bands on the lateral margins.(2)
