Position among New York species of Hoplitis 
Mitchell (1962) lists 6 native species of Hoplitis that are known 
from or might be expected to occur in New York State. Most are 
less robust and smaller than H. anthocopoides ; only H. cylindrica 
(Cresson) and H. truncata (Cresson) typically overlap it in size. 
In Mitchell’s key to the species of Hoplitis based on females, the 
second alternative of couplet 4 should lead to ( Hoplitis s.s.) as well 
as to {Alcidamea) , and should direct the user to 6a. 
Couplet 6a may be inserted to follow 6 as follows: 
6a (4) Apical margin of clypeus crenulate (Fig. 2) ; first flagellar 
segment of antennae subequal to 2 plus 3 ; mandibles long, nar- 
rowed medially (Fig. 4) . ( Hoplitis s.s.) anthocopoides Schenck 
Apical margin of clypeus not crenulate; first flagellar segment of 
antennae shorter than 2 plus 3 ; mandibles short and broad, not 
narrowed medially ( Alcidamea ) 7 
In Mitchell’s key to the males, couplet 4 should be modified as 
follows : 
4(2) Small (8 mm or less) ; antennae filiform, median segments nar- 
row and elongate; abdominal tergum 7 simple, broadly rounded 
( Robertsonella ) 5 
Larger (8 mm or more) ; antennae modified, median segments not 
much longer than broad; abdominal tergum 7 produced to pointed 
or truncate apex 7 
Hoplitis anthocopoides then runs to couplet 8, which should be 
changed as follows: 
8. Clypeus with appressed tomentum; margins of abdominal sterna 
1 and 2 with slender median spines 
( Monumetha ) albifrons Kirby 
Clypeus with long erect pubescence; margins of abdominal sterna 
1 and 2 without spines 9 
9. Apical segment of antennae curved, tapering to a point; pedicel 
nearly concealed by scape ( Alcida?nea ) truncata Cresson 
Apical segment of antennae straight, rounded; pedicel largely ex- 
posed (Fig. 3) ( Hoplitis s.s.) anthocopoides Schenck 
Distribution and Biology 
In Europe, Hoplitis anthocopoides collects pollen exclusively from 
2 species of blue-flowered Boraginaceae, Echium vulgare Linnaeus
