ABSTRACT

A new oil-collecting bee, the smallest in the winter rainfall region, is described. It is
restricted to mountainous areas, from Clanwilliam to Springbok. Females collect oil from
Hemimeris racemosa and Colpias mollis (Scrophulariaceae) and are the only known
pollinators of the latter. The species can be recognized by its small size, the presence of
white hair bands on the apical margins of the metasomal terga and the shape of the genitalia
and terminal sterna of the male.

INTRODUCTION

For the past ten years we have been investigating the relationship between
oil-collecting bees of the genus Rediviva and oil-secreting host plants in the
Scrophulariaceae and Orchidaceae in southern Africa (Whitehead & Steiner
1985, 1992, 1993; Steiner & Whitehead 1990, 1991). In the arid areas of the
western Cape, we have discovered several new species of Rediviva. One of the
most distinctive of these, a small dark bee with prominent white banding on the
abdomen, is described below.

METHODS

Details of the methods of preparation and measurement of the various body
parts are given in Steiner & Whitehead (1990) and Whitehead & Steiner (1992).
The location and structure of hairs specialized for oil-collecting were deter-
mined by sampling pubescence from several areas on the tarsi of the anterior
and middle legs. These hairs were dehydrated in 96 per cent ethyl alcohol and
mounted in Euparal. Illustrations were made using a drawing tube at a magnifi-
cation of 125 times. Morphological terms follow Michener (1981), except for
numbering of individual tarsal segments, which was necessary to characterize
more precisely the location of the various forms of the oil-collecting hairs
(Whitehead & Steiner 1993). Surface sculpturing terms used are those of Harris
(1979).

DESCRIPTION

Rediviva albifasciata sp. nov.
Figs 1-5

Diagnosis

Rediviva albifasciata is the smallest of the oil-collecting bees in the winter
rainfall region, with a body length of 8-10 mm in females and 7-8 mm in
males. In addition, it is the only bee in this area that has white hair bands on the
apical margins of metasomal terga 1-4. Forelegs of females are not attenuate
and are approximately three-quarters the length of the body. The dorsally
flattened apical half of the gonostylus, the shape of the apical and lateral lobes
of S7 and the entire (not emarginate) apical margin of S8 in males, are
additional characters that make this bee distinctive.

Rediviva albifasciata may be confused with the small form of R. politissima
(Cockerell) of the eastern Cape, which also has white hair bands on the apical
margin of the metasomal terga. However, the latter species can be distinguished
by the smooth, shiny appearance of the metasomal terga, longer front legs of the
female, and differences in genitalia and sterna 7-8 of males.

Type locality
Cape Province, 23 km south of Springbok, farm Mesklip, 2917DD.

Etymology

Albus and fascia, Latin for white and a band, referring to the prominent
bands of white hairs on the apical margin of the metasomal terga.

Host flower records

Females collect oil and pollen from Colpias mollis E. Meyer ex Benth. and
Hemimeris racemosa (Houtt.) Merrill (Scrophuiariaceae) and nectar from Oxalis
pes-caprae L., Oxalis sp. (Oxalidaceae) and Cysticapnos vesicularis (L.) Fedde
(Fumariaceae). Males have been captured taking nectar from Othonna arbuscula
(Thunb.) Schultz-Bip. (Asteraceae), Oxalis pes-caprae L. and O. comosa
E. Meyer ex Sond. (Oxalidaceae). Males also patrol the two oil-producing
plants presumably in search of receptive females.

A NEW SPECIES OF BEE FROM NORTH-WESTERN CAPE PROVINCE iE

Distribution

Rediviva albifasciata occurs mainly in the mountainous regions of northern
Namaqualand, but also has disjunct populations 300 km south in the Clan-
william area (Fig. 5).

ACKNOWLEDGEMENTS

The Department of Nature and Environmental Conservation of the Cape
Province is thanked for permission to work on the Goegap Reserve (formerly
Hester Malan) at Springbok. The assistance of Senior Conservators J. (Kobus)
Kritzinger and N. J. (Klaas) van Zyl, who were in charge of the above reserve
during our period of research, is much appreciated. We are grateful to
Dr Michael Struck of Botany Department, University of Cape Town, for the
donation of several male specimens of the new species. We would also like to
express our appreciation to the referees for their constructive comments and
suggestions and for detection of some basic errors in the table.

6. SYSTEMATIC papers must conform to the /nternational code of zoological nomenclature (particu-
larly Articles 22 and 51).

Names of new taxa, combinations, synonyms, etc., when used for the first time, must be followed
by the appropriate Latin (not English) abbreviation, e.g. gen. nov., sp. nov., comb. nov., syn. nov.,
etc.

An author’s name when cited must follow the name of the taxon without intervening punctuation
and not be abbreviated; if the year is added, a comma must separate author’s name and year. The
author’s name (and date, if cited) must be placed in parentheses if a species or subspecies is trans-
ferred from its original genus. The name of a subsequent user of a scientific name must be separated
from the scientific name by a colon.

Synonymy arrangement should be according to chronology of names, i.e. all published scientific
names by which the species previously has been designated are listed in chronological order, with all
references to that name following in chronological order, e.g.:

Family Nuculanidae
Nuculana (Lembulus) bicuspidata (Gould, 1845)

Figs 14-15A
Nucula (Leda) bicuspidata Gould, 1845: 37.
Leda plicifera A. Adams, 1856: 50.
Laeda bicuspidata Hanley, 1859: 118, pl. 228 (fig. 73). Sowerby, 1871: pl. 2 (fig. 8a—b).
Nucula largillierti Philippi, 1861: 87.
Leda bicuspidata: Nicklés, 1950: 163, fig. 301; 1955: 110. Barnard, 1964: 234, figs 8-9.

Note punctuation in the above example:
comma separates author’s name and year
semicolon separates more than one reference by the same author
full stop separates references by different authors
figures of plates are enclosed in parentheses to distinguish them from text-figures
dash, not comma, separates consecutive numbers.

Synonymy arrangement according to chronology of bibliographic references, whereby the year is
placed in front of each entry, and the synonym repeated in full for each entry, is not acceptable.

In describing new species, one specimen must be designated as the holotype; other specimens
mentioned in the original description are to be designated paratypes; additional material not regarded
as paratypes should be listed separately. The complete data (registration number, depository, descrip-
tion of specimen, locality, collector, date) of the holotype and paratypes must be recorded, e.g.:

Holotype
SAM-—A13535 in the South African Museum, Cape Town. Adult female from mid-tide region, King’s Beach, Port Eliza-
beth (33°51’S 25°39’E), collected by A. Smith, 15 January 1973.

Note standard form of writing South African Museum registration numbers and date.

7. SPECIAL HOUSE RULES

Capital initial letters

(a) The Figures, Maps and Tables of the paper when referred to in the text
e.g. ‘. . . the Figure depicting C. namacolus .. .’: ‘. . . in C. namacolus (Fig. 10)...’

(b) The prefixes of prefixed surnames in all languages, when used in the text, if not preceded by
initials or full names
e.g. DuToit but A.L.du Toit; Von Huene but F. von Huene

(c) Scientific names, but not their vernacular derivatives

e.g. Therocephalia, but therocephalian

Punctuation should be loose, omitting all not strictly necessary

Reference to the author should preferably be expressed in the third person

Roman numerals should be converted to arabic, except when forming part of the title of a book or
article, such as
‘Revision of the Crustacea. Part VIII. The Amphipoda.’

Specific name must not stand alone, but be preceded by the generic name or its abbreviation to initial
capital letter, provided the same generic name is used consecutively. The generic name should
not be abbreviated at the beginning of a sentence or paragraph.

Name of new genus or species is not to be included in the title; it should be included in the abstract,
counter to Recommendation 23 of the Code, to meet the requirements of Biological Abstracts.
