Hylaeus

Subgenus Prosopis Fabricius (6 sp.)

Keys to the subgenus Prosopis in Florida

In addition to the species in the key, Mitchell listed H. modestus as also occurring in Florida. No specimens of this species from Florida have been seen.

Key to females (From Mitchell 1960)

1. Collar entirely black….2



Collar maculated…3



2. Base of abdomen red; pleura rugose, the punctures very closely crowded..H. nelumbonis

Abdomen entirely black; thorax coarsely sculptured; wings fuliginous except at base..H. schwarzii



3. Tegulae maculated…4



Tegulae not maculated…5

4. Entire clypeus and basal segments of abdomen bright ferrugineous, the lateral face marks, maculations of collar and the pronotal tubercles pale yllow or ivory..H. volusiensis

Clypeus and abdomen black..H. confluens



5. Clypeus entirely ferrugineous, the lateral face marks ivory..H. volusiensis

Clypeus black, lateral face marks yellow..6

6. Segments 1 and 2 of abdomen and mid and hind legs entirely bright ferrugineous; wings hyaline…H. flammipes

Second abdominal segment, and mid and hind femora black; apical half of wings infuscated…H. ornatus

In the above key to females, H. volusiensis comes out in two places due to variation in whether the tegulae are maculated or not.

Key to males (From Mitchell 1960)

1. Pleura coarsely rugose….2



Pleura with distinctly separated punctures, though these punctures possibly coarse and and quite close…5



2. Collar black…3



Collar maculated…4



3. Base of abdomen usually red; pleural punctures closely crowded, more definitely rugose..H. nelumbonis

Abdomen entirely black; pleura not so definitely rugose, the coarse punctures slightly separated in part. .H. schwarzii



4. Tegulae maculated (occasionally an individual will have weak maculation or lack maculae entirely); punctures on scutum and scutellum coase and crowded; hind tibiae dark apically..H. confluens



Tegulae entirely dark; punctures on scutellum distinctly more coarse and sparse than those on scutum; base of abdomen red…H. ornatus



5. Base of abdomen ferrugineous, in marked contrast to the blackish 2^nd and following segments; facial and thoracic maculae ivory-colored..H. volusiensis
6. 

Abdomen of uniform color, either black or dark ferrugino-piceous; maculae usually yellow; larger (7mm), collar entirely black, pleura dull and densely rugose..H. schwarzii

 

Note that males of H. flammipes have not been described. H. schwarzii comes out in 2 locations in the key based on variation in rugosity of the pleura. I have also verified that the maculation of the tegulae varies in H. confluens (absent in a few individuals)
