Abstract
Survey made on certain plants at different localities
in Egypt gave knowledge about more hosts and aiming
to find new records of species in the Egyptian fauna.
This work indicates also that, the collecting host
plants are related to families, Umbelliferae, Labiatae,
Geraniaceae, Leguminosae, Cruciferae, Compositae,
Malvaceae and Tamaricaceae; it was observed that the
species of the family Colletidae visiting the blooming
plants from January till April, this work indicates that
the species of family Colletidae were collected from
many Governorates in Egypt extending from Alexandria
Governorate in north to Qena Governorate in south.
The present work revealed that family Colletidae in
Egypt represented by two subfamilies including sixteen
species : 1. Subfamily Hylaeinae (Prospinae) includes ten species
in Egypt within one genus, three species are new
records :
:1. Prosopis albonotata Walk.
2. l. brevlcornis (Nyl.) (new record).
3. P. cypricola Walck.
4. P. dinkleri Fr.
5. P. gibba (Saund)•
6. P. klugi Fr.
7 • P. nigrifacies :b1r.
8. P. pWlCtata Br. (new record) .
9· P. variegata (F.) (new record) •
10. ~.xanthopoda Vach.
2. Subfamily Colletinae recorded by one genus which includes
six species, three of them were first record :
1. Colletes cariniger Perez (new record) 2. C. lacunatus Deurs.
J. Q. maidli Hosk. (new record) .
4. C. nanus Fr.
5. Q. perezi Morice.
6. Q. pumilus Morice (new record).
Keys are constructed to separate the above species
based upon the external taxonomic characters of males
and females. These taxonomic characters which are used
for separating the Egyptian species belonging to genus
Prosopis were, the lateral face marks that portion between
orbit, clypeuB,supraclypeal area and compound eyes;
frontal hook; punctures and net-like on face; wing
venation; size and colour of scape; the colour of
mandibles and labrum; yellow markings on collar, tegula
and tubercles; yellow mark on legs.
But the taxonomic characters which are used for
separating the Egyptian species belonging to genus
Colletes were, wing venation; facial fovea; punctures
and net-like on face; colour of mandibles, labrum and
scape of antennae; the length of the joints of flagellum;
the length and colour of tarsus and the abdominal bands.
The present work also report redescription in
detail of all the species belonging to the family Colletidae
in Egypt including the external characters of adult,
and male genitalia with illustrated plates.
