The primary type material of the family Tachinidae (Diptera) housed in
the Canadian National Collection of Insects, as of 31 December 1994, is
cataloged. The Tachinidae collection contains 897 holotypes, 239 associated
allotypes, 35 lectotypes (no associated allolectotypes), 2 neotypes, and
117 species that are represented by syntypes. Reference to the original
description of each taxon is cited. Label data associated with the specimens
are quoted fully, except for paratypes and paralectotypes. A bibliography
and an index to named taxa are provided. Certain lectotype fixations,
particularly by Mesnil for nominal species described by Villeneuve, are
recognized for the first time.
This work is the fourth, and last, in a series of catalogues on the Diptera
types in the Canadian National Collection of Insects (CNC). The first,
published in 1991, dealt with the Nematocera. The second, published in
1993, documented the types of brachyceran Diptera exclusive of the Schizophora.
The third, currently in production, will cover the Schizophora exclusive
of the Tachinidae. A brief history of the Diptera collection in the CNC
is given in Part 1 of this series.
It is estimated that the Canadian National Collection of Insects houses
approximately 250,000 specimens of the family Tachinidae. A large portion
of these were collected by past members of the Diptera Unit, particularly
A.R. Brooks, C.H. Curran, J.F. McAlpine, G.E. Shewell, J.R. Vockeroth,
and D.M. Wood. The collection has been enhanced significantly by the addition
of the personal tachinid collections of H.J. Reinhard (acquired 1968;
specimens collected mostly from southwestern United States and Mexico),
L.P. Mesnil (acquired 1970-1986; Old World specimens, including many types
of J. Villeneuve), and W.R. Thompson (acquired 1969; Trinidad specimens),
and through purchase of South American specimens from such private collectors
as F. Plaumann and L.E. Peña. Holdings of Tachinidae in the CNC
are largest for the Nearctic and Neotropical regions, though all zoogeographic
regions of the world are represented.
The number of primary types of Tachinidae in the CNC, as of 31 December
1994, totals 1051. More than 90% of these represent nominal species described
by seven authors, namely H.J. Reinhard (267 primary types), L.P. Mesnil
(250), J. Villeneuve (178), W.R. Thompson (118), C.H. Curran (91), A.R.
Brooks (58), and J.D. Tothill (22).
The format of this work is very similar to that in previous Parts of
the series. Entries are arranged alphabetically by genus and species,
using the original combinations and spellings. Subgeneric names are included
if they were used in the original description of a new species, and are
placed in alphabetical order following names without subgenera. Each entry
includes the following information: name of taxon and author, year of
publication, abbreviated reference (volume number and page where description
begins), and current name of country of origin of holotype. Label data
associated with each primary type and allotype are cited in full, with
diagonal lines separating information given on separate labels (a diagonal
line not followed by a space indicates that the diagonal line is present
on the label). The number of paratypes or paralectotypes is given along
with their country or province/state of origin. The sex of each specimen
is given. Notes about nomenclature, genitalic dissections, major damage
to primary types, etc., are included under Remarks. For additional information
about the names of Mesnil, see "The tachinid taxa of Louis P. Mesnil,
with notes on nomenclature (Insecta: Diptera)" (O'Hara, in press).
Certain lectotype fixations, particularly by Mesnil for nominal species
described by Villeneuve, are recognized for the first time.
