THE TYPE SPECIES OF THE GENERA AND SUBGENERA 
OF BEES 
By Grace A. Sandhouse ^ 
INTRODUCTION 
This pcaper ^ lists the genera and subgenera of the bees (super- 
family Apoidea) and in each case cites what is considered to be the 
earliest correct genotype designation. Dalla Torre's Catalogus 
Hymenopterorum, the Zoological Record, and a card catalog of genera 
and species in the United States National Museum served as a basis 
for the preparation of this work. Emendations and some lapsi have 
been included, but not all the typographical errors. Nomina nuda 
are also recorded in order that possible uncertainty concerning the 
status of such names may be removed. 
The first generic name to be proposed for a group of bees was Apis 
Linnaeus, 1758. By 1800 only 4 other names had been added : Eucera 
and Nomada Scopoli, 1770; Amlrena Fabricius, 1775; and Hylaeus 
Fabricius, 1793. Beginning with 1800, however, the number of gen- 
J Died on November 9, 1940. 
* AUhough Miss Sandhouse had prepared the first draft of the manuscript before her 
death, she had no opportunity to review it critically and to put it into final form. 
P. W. Oman and I have attempted to do this. In the treatment of the names belonging in 
the Osmiiiiae and in the Bombidae we have been appreciably assisted by C. D. Michener 
f and Dr. T. H. Frison, respectively, and this aid is gratefully acknowledged. In accord 
with the practice followed in other lists of this kind a genus containing only one specific 
i* name treated as valid is regarded as monobasic, although one or more synonyms may hare 
been listed by the author of the generic name. Exceptions fiave been made, however, in 
the case of Ahrupta M6hely, and of Fasciata M6hely, two names proposed since December 31, 
] 1930, when Article 25c of the International Rules became effective. — C. F. W. Muesebeck,

eric and siibgeneric names increased rapidly. Fifty-nine genera were 
established from 1800 to 1810 inclusive; 28 genera and 1 subgenus 
from 1811 to 1840, inclusive; 191 genera and 60 subgenera from 1841 
through 1&'99 ; and 281 genera and 103 subgenera from 1900 through 
1938. 
As is frequently true in an undertaking of this kind, the current 
interpretations of some well-known genera have been found to re- 
quire modification. An attempt has been made to adhere strictly to 
the rules and opinions of the International Commission on Zoological 
Nomenclature, and reference is made to the rules or opinions on which 
the conclusions are based in the discussions under some of the genera. 
Recently some proposals for the suspension of the Rules of Nomen- 
clature with reference to generic names in the bees have been sub- 
mitted to the International Commission, and these are also mentioned 
under the names which would be affected. However, such proposals 
cannot be accepted until opinions on them have been rendered and 
published. 
The names of Jurine's genera that appeared in the "Erlangen 
List" ^ have recently been invalidated by Opinion 135 of the Inter- 
national Commission. The genotype designations of Latreille (1810) 
are considered valid by the International Commission (Opinion 11). 
Megachile^ Centris^ and Anthophora, however, were cited by Latreille 
with more than one species included under each and consequently 
cannot be regarded as having received type fixation in that publica- 
tion (Opinion 36). 
The necessity for a definite genotype designation for each genus or 
subgenus has been accepted by most systematic entomologists, and at 
its meeting in Budapest in 1927 the International Zoological Con- 
gress passed an amendment to Article 25 (law of priority) according 
to which a genus proposed after December 31, 1930, without a definite 
unambiguous designation of the type species, is to be considered as 
invalid under the Rules. Fortunately only a few names in the list that 
follows are affected by this ruling. 
The terminology used in the present list is essentially that contained 
in Article 30 of the International Rules with the following excep- 
tions : Mo7iohasiG is here used instead of mo)iof>/pw, and isogenotypio 
is used in reference to two or more genera that have the same species 
as genotype. 
The original work covered by each citation has been consulted, unless 
a statement to the contrary follows the reference. The dates of pub- 
lication given by Sherborn in his Index Animalium have been used 
for most of the names published before 1850. These, in most in- 
' Erlangen Litteratur-Zeitung, vol. 1, p. 164, 1801. 
GENERA AND SUBGENERA OF BEES — SANDHOUSE 521 
stances, are in agreement with those given in Nomenclator Animalium 
Genera et Subgenera, published by the Preussische Akademie der Wis- 
senschaften in Berlin (not yet complete), and Neave's Nomenclator 
Zoologicus, the final volume of which appeared in 1940. It should bo 
noted, however, that the latter cites 1805 instead of 1804 as the date of 
publication of Fabricius' Systema Piezatorum, in agreement with the 
conclusions published by Kichards.* 
In arrangement this catalog follows rather closely that adopted by 
Kohwer, Viereck, and Gahan and Fagan in earlier genotype catalogs 
of other groups of Hymenoptera. The generic and subgeneric names 
are listed alpliabetically with reference to the original description; 
and, if no species was originally included, the citation to the work in 
which the first species was assigned is given also. The number of 
species originally included is shown except in the case of monobasic 
genera. In each case mention of the genotype is followed by the date 
of original description and by an indication of the character and place 
of type fixation. If the genotype is considered to be a synonym, the 
name is enclosed in parentheses and is followed by the name of the 
valid species. Erroneous type designations are mentioned, together 
witli reasons for considering them invalid.

Curtis, Brit. Ent., vol. 8, expl. pi. 357, 1831, was not originally included in

Anthophora was proposed by Latreille to replace Podalirius Latreille which 
he considered to be preoccupied by Podalirius Lamarck, 1801, used for a 
genus of plants. The placement of Anthophora Latreille on the Official 
List of Generic Names is under consideration by the International Com-

The year of publication of the name Bremus Panzer is not certain. Sherborn, 
Ann. Mag. Nat. Hist., ser. 9, vol. 11, p. 5G7, 1923, has indicated that Heft 85 
of the Panzer work may have appeared as early as 1801, although Heft 86 
was not published until 1804. In view of this situation and taking into 
consideration the proposal by Richards {I. c.) that "Bombus Latreille, 1802 
(type Apis tcrrestris Linnaeus, 1758) be added to the Official List of Generic 
Names," and "Bremus Panzer, 1801 ... be set aside and have no status in

Isogenotypic with Ctenoplectra F. Smith. 
Since the only character given by Kirby for Ctenoplectra (the crescent-shaped 
inner calcar of the hind tibia, with its inner edge finely pectinate) is in 
agreement with Smith's description and illustration of that structure in 
his species chalybea, that species is transferred to Ctenoplectra Kirby and 
designated its type. Apparently Ctenoplectra Kirby has, until now, been 
a gonus without species.
