SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION

The emphasis upon publications as a means of diffusing knowledge was expressed

by the first Secretary of the Smithsonian Institution. In his formal plan for the Institution, Joseph Henry articulated a program that included the following statement:

"It is proposed to publish a series of reports, giving an account of the new discoveries

in science, and of the changes made from year to year in all branches of knowledge."

This keynote of basic research has been adhered to over the years in the issuance

of thousands of titles in serial publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing

with the following active series:

Smithsonian Annals of Flight

Smithsonian Contributions to Anthropology

Smithsonian Contributions to Astrophysics

Smithsonian Contributions to Botany

Smithsonian Contributions to the Earth Sciences

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Studies in History and Technology

In these series, the Institution publishes original articles and monographs dealing

with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired

facts, synoptic interpretations of data, or original theory in specialized fields. These

publications are distributed by mailing lists to libraries, laboratories, and other interested institutions and specialists throughout the world. Individual copies may be

obtained from the Smithsonian Institution Press as long as stocks are available.

Notes on Neotropical

Mesostigmata VI:

Four New Venezuelan

Species of the Genus

Periglischrus

(Acarina; Spinturnicidae)

In a previous paper one of us (Machado-Allison,

1965b) pointed out that careful collecting of bats

and their ectoparasites might possibly lead to the discovery of new species of Periglischrus Kolenati. The

description of four new mite species parasitic on the

bat genera Trachops, Mimon, Lonchorina, and

Rhinophylla, all belonging to the Phyllostomidae,

confirms this prediction. In the present paper we

shall also discuss the contention of Furman (1966)

that the genus Cameronieta Machado-Allison, 1965,

is a synonym of Periglischrus; the validity of species

described by Furman (1966) and by one of us

(Machado-Allison, 1964, 1965b); and several existing

points of confusion relative to the publication date

of some species descriptions. Observations on geographic distribution, host-parasite relationships and

intraspecific variation of some forms will be the subject of later communications.

This paper is a contribution of the Smithsonian

Venezuelan Project, supported by a contract (DA49-193-MD-2788) of the Medical Research and

Development Command, Office of the Surgeon General, United States Army.

Genus Cameronieta Machado-Allison

Cameronieta Machado-Allison, 1965:243.-Dusbabek, 1967:149.

Periglischrus.—Furman, 1966:166.

C. E. Machado-Allison and Rafael Antequera. Inslituto de

Zoologia Tropical, Universidad Central de Venezuela, Caracas.

Furman (1966) considered Cameronieta to be a synonym of Periglischrus, stating that the figure and

description of C. thomasi agrees "with the specimens

I have described as heteromorphic females of Periglischrus elongatus." In another paragraph, describing P. elongatus, Furman referred to the characteristics of both specimens considered as "abnormal females" which are, in effect, similar to those specimens which I have considered adult females of C.

thomasi. There is no doubt that the material described by him, Periglischrus strandtmanni Tibbets and the new species described by Dusbabek

(1967) from Cuba (Cameroniela machadoi, C. torrei, and C. tibbetsi), all have been obtained from

chilonycterine bats and that all possess morphological characteristics similar to C. thomasi. On the other

hand it is extremely difficult, with our present state

of knowledge of the biology of the Spinturnicidae,

to accept the idea that incrusted adult females with

developed sclerotized camerostome, pectinated hairs,

sternal plate fused to the first pair of coxae and

wider than long, etc., are simple heteromorphic forms

of a typical Periglischrus. To the above, we should

add the fact, undoubtedly of biological importance,

that the so-called abnormal or heteromorphic forms

are precisely those which we have found with larvae

inside them. From our point of view, this justifies

the selection of these forms as representatives of the

species. A negative observation, i.e., failure to find

non-incrusted females (which differ from incrusted

larvae inside them, would be equally valid if these

forms really belong to the same species. Even though

the former observations and the host-parasite specificity are sufficient to retain Cameronieta as a valid

genus, we offer in the tabulation above a further

analysis of the morphological characteristics of the

"typical Periglischrus," and the "incrusted" and

"free" forms of Cameronieta

The tabulation shows that there is much greater

affinity between the non-incrusted and incrusted

forms of Cameronieta than between either of these

and any of the Periglischrus species, a circumstance

strengthened by the absence of any species which

combines intermediate morphological characteristics. But it must also be pointed out that between

the males of the two genera, the differences are much

less important, for the shape of the ventral plate and

the chaetotaxy of the legs and of the posterior intercoxal area is similar in the males of both genera. In

general, the main differences are the presence of

small thorns on the tegument and a certain dilatation and striation of the ventral plates; these could

indicate a close relationship between Cameronieta

and Periglischrus, and thus we consider them as a

taxonomic unit within the family, but at the same

time definitely separated from each other. There is

also a certain likeness between the males of Cameronieta and of Eyndhovenia, a genus which parasitizes

the bat family and is distributed throughout the Old

World.

Finally, it is useful to point out the existence of

very peculiar host-parasitic relationships between the

genus Cameronieta and the Chilonycterinae. In a

previous paper one of us (Machado-Allison, 1967)

analyzed the relationships between the Spinturnicidae and Phyllostomidae, and concluded that the

Desmodidae must be considered as a part of the

family Phyllostomidae, while the Chilonycterinae,

until now considered as a subfamily of Phyllostomidae, should be considered as a separate family. On

the other hand, in their analysis of the host-parasite

relationships of the Streblidae (Diptera), Wenzel,

Tipton, and Kiewlicz (1966) "supported the view

of Dalquest and Werner (1954) and De La Torre

(1962) that the Chilonycterinae should be regarded
NUMBER 93

as a separate family of Vespertilionoidea rather than

a subfamily of Phyllostomidae."

Genus Periglischrus Kolenati

Periglischrus Kolenati, 1857:60.

Periglischrus acutisternus Machado-Allison

P. caligus Kolenali, 1857:60.—Rudnick, 1960:196.—Furman,

1966:166.

P. tiptoni Funnan, 1966:144.

Furman in his "addendum" (1966:166) pointed out

that "P. tiptoni is a synonym of P. acutisternus

Machado-Allison." In a previous paper one of us

(Machado-Allison, 1965b) gave the year 1965 as publication date for acutisternus, referring to a paper

then in press; however, the original description of

P. ojastii, P. acutisternus, and P. parvus appeared in

December 1964 (see Literature Cited), hence this

correction.

Periglischrus caligus Kolenati

P. caligus Kolenati, 1857:60.-Rudnick, 1960:196.—Furman,

1966:142.

P. setosus Machado-Allison, 1964:199; 1965:271.

Machado-Allison (1965:271) pointed out "la descripci6n original de Kolenati no permite la identificacidn de esta especie y conservamos a setosus como

una especie valida hasta poder compararla con el

tipo de caligus." Furman (1966:142) says, without

further comment: "I consider P. setosus MachadoAllison to be a synonym of caligus Kolenati." On the

basis of the description and figures given by Furman,

and on material identified by Kolenati as caligus,

we consider this opinion valid; however, there is

doubt as to whether P. vargasi Hoffmann (a closely

related species), which is also collected on Glossophaga, might be identical to the type of caligus, the

location of which has been unknown until now.

Periglischrus ojastii Machado-Allison

P. ojastii M.ichado-Allison, 1964:197; 1965:268.-Furman, 1966:

166.

P. aitkeni Furman, 1966:137.

Concerning the date of publication of this species,

see comments under P. acutisternus.

Periglischrus parvus Machado-Allison

P. parvus Machado-Allison, 1964:195; 1965:268.

The correct date of publication is the same as that

for acutisternus and ojastii. Furman (1966:166)

pointed out that "P. micronycteridis Furman may

be a synonym of P. parvus Machado-Allison. Both

occur on Micronycteris species, but the photomicrographs and key characters given for P. parvus are

inadequate for certain identification." It is evident,

in spite of Furman's comments, that parvus and

micronycteridis have many common characteristics,

but the shape of the sternal plate and the medial

plate in the females (compare Figures 6 and 23 of

Machado-Allison, 1965, and Plate-figures 45:1 and

2 of Furman, 1966) are different in the two species.

In addition, the pale band of the scutum of parvus

is absent in micronycteridis and the peculiar sculpture of the fore section of the scutum of micronycteridis is absent in parvus. We have had the opportunity to compare a para type of micronycteridis from

Micronycteris megalotis, several specimens from

Venezuela collected also on M. megalotis, a few others from M. minuta, and material collected on M.

nicefori, all with the type of parvus. It is clear to

us that these two species are quite different.

Periglischrus torrealbai Machado-Allison

P. torrealbai Machado-Allison, 1965:276.-Furman, 1966:166.

P. inflatiseta Furman, 1966:134.

Without a doubt, the synonym of inflatiseta with

torrealbai (Furman, 1966:66) is valid. It is interesting to note that we have observed one female, also

collected on Phyllostomus hastatus, which differs

somewhat in that the setae are acicular instead of

inflated as the rest of the known specimens.

Periglischrus par acutisternus^ new species

FIGURES 47-61

Periglischrus tiptoni Furman 1966:144 (part) .

Periglischrus acutisternus Machado-Allison.—Furman 1966:166

(part).

On the basis of material collected on Phyllostomus

hastatus and Trachops cirrhosus, Furman described

P. tiptoni. Paratypes of P. tiptoni from T. cirrhosus

belong to a related but new species of Periglischrus.

Since P. tiptoni (the holotype) was described from

specimens collected on P. hastatus which are identical to P. acutisternus Machado-Allison, the material

from T. cirrhosus should be described as a new

species.

DESCRIPTION (Female).—Idiosoma 935±25 [i long.

Dorsum: Scutum 400±9 n long, with eleven pairs

of pores on anterior plate (six large and five small),

eleven on the posterior plate; pale band present but

short. Sculpturing poorly defined. Propodosomal

setae 20, 28, 25, 25, and 25 p. in length, respectively,

from first to fifth pairs. Metapodosomal setae 25 it

long. Opisthosomal setae very small, hard to see at

high magnifications; one very small pair of postanal

setae, 5 p. long. Peritreme long and thin.

Venter: Sternal plate 134±3 /* long by 82±2 ft wide

at level of first and 82±3 p wide at level of second

pair of pores; anterior edge presents subtriangular

projection very much like that existing in P. acutisternus, but varying in size; sternal setae very thin,

14 n long; metasternals somewhat shorter, 12 /x long.

Epigynial setae very small but somewhat more robust

than sternals. Opisthosoma with sclerotized plates

well developed with setae longer than dorsals, 16 p

long. Medial plate robust 172±3 ^ long, 86±2 /x wide

at level of anterior pair of setae. Anterolateral plate

with a characteristic postero-external sinuosity. Opisthosoma with eight pairs of setae in addition to

adanal pair.

Legs: External edge of coxa 1 68±0.6 p. long; trochanter 1 123 ^ wide at base; tarsus 1 68 n wide at

base. Dorsal and ventral chaetotaxy as in figures.

Gnathosoma: Dorsal setae reaching 16 JX, basals

shorter, not more than 10 ^ long.

DESCRIPTION (Male) .—Idiosoma 442 JU. long.

Dorsum: Scutum long, 399 fi in length, edges

slightly marked; pale band conspicuous. Propodosomal setae erect, the first two pairs groups, 24 and 34 it

long, respectively; third to fifth pairs also grouped,

33, 29 and 29 i± long respectively. Metapodosomal

setae 33 ii long.

Venter: Holoventral plate 196 ti long, of which

only 37 /* corresponds to the genital area, 160 p wide

at level of anteroexternal setae. Genital setae 55 ju,

long; anteroexternals and posteroexternals 49 /* long;

medials and posteriors 43 (i long. One pair of very

small setae behind ventral setae. Area between posterior coxae with six pairs of setae in addition to

adanal pair.

Legs with strong erect ventral setae on legs III and

IV; chaetotaxy as in figures.

Gnathosoma with thin basal setae, 19 ^ long; distals stronger, short, 16.5 /i long.

Publication in Smithsonian Contributions to Zoology

Manuscripts for serial publications are accepted by the Smithsonian Institution Press

subject to substantive review, only through departments of the various Smithsonian museums.

Non-Smithsonian authors should address inquiries to the appropriate department. If submission

is invited, the following format requirements of the Press should govern the preparation of copy.

Copy must be typewritten, double-spaced, on one side of standard white bond paper, with

\W top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompanied by the original artwork. Duplicate copies of all material, including illustrations, should

be retained by the author. There may be several paragraphs to a page, but each page should

begin with a new paragraph. Number all pages consecutively, including title page, abstract,

text, literature cited, legends, and tables. A manuscript should consist of at least thirty pages,

including typescript and illustrations.

The title should be complete and clear for easy indexing by abstracting services. Taxonomic

titles will carry a final line indicating the higher categories to which the taxon is referable:

"(Hymenoptera: Sphecidae)." Include an abstract as an introductory part of the text. Identify

the author on the first page of text with an unnumbered footnote that includes his professional

mailing address. A table of contents is optional. An index, if required, may be supplied by the

author when he returns page proof.

Two headings are used: (1) text heads (boldface in print) for major sections and chapters

and (2) paragraph sideheads (caps and small caps in print) for subdivisions. Further headings

may be worked out with the editor.

In taxonomic keys, number only the first item of each couplet; if there is only one couplet,

omit the number. For easy reference, number also the taxa and their corresponding headings

throughout the text; do not incorporate page references in the key.

In synonymy, use the short form (taxon, author, date, page) with a full reference at the

end of the paper under "Literature Cited." Begin each taxon at the left margin with subsequent lines indented about three spaces. Within a taxon, use a period-dash (.—) to separate

each entry. Enclose with square brackets any annotation in or at the end of the taxon. For

synonymy and references within the text, use the author-date system: "(Jones 1910)." Use

the colon system for page references: "(Jones 1910:122)," and abbreviate further data:

"(Jones 1910:122, fig. 3, pi. 5: fig. 1)."

Simple tabulations in the text (e.g., columns of data) may carry headings or not, but they

should not contain rules. Formal tables must be submitted as pages separate from the text, and

each table, no matter how large, should be pasted up as a single sheet of copy.

Use the metric system instead of (or in addition to) the English system.

Illustrations (line drawings, maps, photographs, shaded drawings) usually can be intermixed throughout the printed text. They will be termed Figures and should be numbered

consecutively; however, if a group of figures is treated as a single figure, the individual components should be indicated by lowercase italic letters on the illustration, in the legend, and

in text references: "Figure 9b." Submit all legends on pages separate from the text and not

attached to the artwork. An instruction sheet for the preparation of illustrations is available

from the Press on request.

In the bibliography (usually called "Literature Cited"), spell out book, journal, and article

titles, using initial caps with all words except minor terms such as "and, of, the." (For capitalization of titles in foreign languages, follow the national practice of each language.) Underscore (for italics) book and journal titles. Use the colon-parentheses system for volume number

and page citations: "10(2):5-9." Spell out such words as "figures," "plates," pages."

For free copies of his own paper, a Smithsonian author should indicate his requirements on

"Form 36" (submitted to the Press with the manuscript). A non-Smithsonian author will

receive fifty free copies; order forms for quantities above this amount, with instructions for

payment, will be supplied when page proof is forwarded.
