Entomologists of the Division of Plant In-
dustry, Florida Department of Agriculture,
provide an identification serve lee for the State
of Florida of insect, mitee, spiders, scor-
pions, millipedes, centipedes and other ar-
thropods, Fairly frequently, scorpions and
other arachnids closely related to scorpions
are received for identification and informa-
tion is requested concerning the virulence of
their stings or bites, their recognition char-
acters, their habits and their control. The
accurate Identification of these groups in
Florida has been confused due to the inade-
quacy of identification keys,. the occurrence of
highly questionable records for Florida which
have appeared In the literature, and the Iack
of detailed descriptions of those species
which are known to occur in Florida; at least
two Florida species have been undescribed,
Dr. Martin H. Muma, Rewearch Associate of
The Florida State Collection of Arthropods
and Technical Advisor to the Florida Depart-
ment of Agriculture, was asked to prepare a
bulletin stressing the recognition and distri-
bution of the species found in the state,
Scorpions, whip scorpion and wind score'
pions are predaceous on other small animals.
mostly upon soft-bodied insects, but aa the
author indicates in this bulletin, only the
scorpions possess poison glands and consti-
tute any danger to man. None of the several
species of scorpions which occur in Florida
ia capable of inflicting a lethal sting. al-
thouhrb the site of the sting may be painful
for several hours. Scorpion venom, a neuro-
toxin, is comparable in toxicity and in its
mode of action to that of the cobra, but the
dose injected by the scorpion usually is in-
sufficient to prove fatal to the human adult.
The potency of the venom varies consider-
ably from one species to another, and even
cJosely related apecles may differ widely in
this respect In North America, species
highly dangerous to humana, eApscia~ly to
children, uccur only in arid regions of the
extreme southwestern United States and

Scorpions, Whip Scorpinrz and Wind Scor-
pions of Florida is the fourth of an irreg-
ularly appearing series of publications relat-
ing to the insects and other arthropods of
Florida and neighboring land areas-the
southeastern United States,. the Bahama Is-
lands, the Greater and Lesser Antilles, and
the land areas in an around the Gulf of Mex-
ico and the Caribbean Sea-with emphasis
on taxonomy, ecology, biology, and zoo-

The files and preserved specimens of the
Florida State Collection of Arthropods pro-
vided a basis for many of the records in this
publication. This collection is being devel-
oped by the staff members of the Entomology
Section, Division of Plant Industry, Florida
Department of Agriculture, and more than
fifty Rewearch Associates of the state ar-
thropod collection. Close support is provided
by staff members in several departments of
the University of Florida, including those in
the Department of Entomology, the Depart-
ment of Biological Sciences, the Department
of Zoology and the Florida State Museum,
The collection is housed in the entomnlogy
building of fhe new Division of Plant In-
dustry headquarters located on the campus
of the University of Florida.

The author, Dr. Muma, was born in To-
peka, Kansas. July 24, 1916. He received his
B, S. degree from Frostburg State Teachers
College in 1989, his M. S. degree from West-
ern Maryland College in 1940, and his Ph. D.
degree from the University of Maryland in
1943. From 1940 into 1945 he served as an
Instructor and Assiatant Entomotogist at the
University of Maryland, then as an Exten-
sion Entomologist and Associate Professor
and Entomologist at the University of Ne-
braska from 1945 into I95l. Since 1951 he
has been an Associate Prufensor, and then a
lull Profesor of Entomology at the Univer.
sity of Florida Citrus Experiment Station
located at Lake Alfred, working primarily
on research relating to the biological control

of citrus inses and mites. In the field of
taxonomy be has made important contribu-
tiona on the taxonomy and biology of citrus
mites, and he is one of the foremost North
American authorities on the taxonomy, bi-

spiders, scorpions and wind seorpluna. He is
the author or coauthor of forty articles in
the field of entomology and forty-five articles
in the field of arachnoslgy, in addition to 21

(Arachnida: Scorpionida, Pedipalpida, and Solpugida)

Martin H. Muma1
University of Florida Citrus Experiment Station
Lake Alfred

Arachnids of the orders Scorpionida, Pedi-
palpida, and Solpugida in Florida have re-
ceived no attention as a group since Nathan
Banks' (1904) presentation of "The Arach-
nida of Florida" 63 years ago. The present
publication reviews the recorded species of
scorpions and their allies in Florida, cites
additional distribution records and, where
possible, gives biological and ecological data
of both scientific and popular interest.
Although an intensive literature search
and a systematic, morphologic investigation
were required to properly identify and name
some included species, this is not primarily a
taxonomic paper. It is, rather, a zoogeo-
graphic presentation of the species found in
the state. Because of a general public in-
terest in scorpions and scorpion-like animals,
information on the habits and habitats of the
various species is included. For the same
reason, known effects of the stings or bites
are cited.
Morphologic drawings have been re-
stricted to those absolutely essential for ac-
curate, scientific diagnosis of new or little-
known species. Most species have been
illustrated by photographs of living or care-
fully arranged museum specimens. These
will help interested Florida residents to
identify these "scorpions" so that they may
read the appropriate paragraphs of this
report and better understand these overly
feared and often maligned animals.

Arthropods, Division of Plant Industry, Florida De-
partment of Agriculture.

Keys to orders, families, genera, and spe-
cies have been prepared for those interested
in technical species identification. Para-
graphs entitled "coloration" and "measure-
ments" also contain technical information.
Paragraphs entitled "remarks" and "rec-
ords" contain both general and technical
information on the occurrence, distribution,
and bites or stings of the cited forms.
Persons interested in learning more about
the lives, habits, and histories of scorpions
and their allies are referred to the following
general works which contain excellent sum-
maries and bibliographies: The Spider Book
by J. H. Comstock (1912, revised 1940) ;
American Spiders by W. J. Gertsch (1949);
The Arachnida by T. H. Savory (1935);
Spiders, Men and Scorpions by T. H. Savory

this form from C. Aentzi, with which it 1bas
been confused for many years. Study of C.
vittatus from Nebraska, Texas, and Mexico
and a compartIso of specimens of C. keysi
with description of C, fhoreli, C. s-uffusu
(Pocock), and C. ornatwu (Pocock) cDnvince
me, however, that C, keysi is equally as dis-
tinruishable from C, hentzi as C. hrntzi is
from C. vitlutzs or C. suffusus and C. oamatu
are from each other and from C. ,ittatua.
The author has been stung while collecting
this species. The sting may be comparable
to that of the honey bee, Apis mellifera (L.),
or a prolonged local staingrI and burning
with tenderness may occur at the A ing site
for several days, arnd a slight neeroeis of the
skin may develop a millimeter or two around
the site.
This species is collected under the aame
conditions aa C. hentra with perhaps more
specimens found on the ground. However,
it is found frequently under the bark of dead
pine and buttonwood trees, especially those
infested with large termites.

Family Schblomidae
Sehisomua floridanum new species
Fig, 13 to 1V

Female holotype in alcohol 3,43 mm long
from anterior projection of propeltidium to
tip of telson. Four slide-mounted female
paratypes measure in length a maximum of
3.31 mm, a minimum of 3,01 nnmm, and a
mean of 3.16 mm. Leg formula 1423. Telt-.
son with three segments.
COLORATION: Sclerites in alcohol some-
what variable in color but generally a pale
yellowish brown with the chelicerae. espe-
cially the movable finger, and pedipalpl pale
reddish brown (Fig. 13). Basal leg seg-
ments slightly darker than apical segments,
which also tend to be lighter toward the
ends. There are no identifiable leg markings
as occur on some species of this genus. See-

ond through sixth abdominal tergites exhibit
an indistinct to distinct circular dark spot on
each side near the lateral margin. Most
sternites and coxae similar in color to but
somewhat paler than dorsal aelerites, but
coxal endites of the palpi are pinkish along
their mesal margins. Obviously immature
specimens off-white to pale yellow in color.
Some apparently penultimate and ma-
ture specimens have a greyish or greenish
elAt. There are pale eye *pots on the pro-
peltidium, and the metapeltidium is pale
meassily but not divided.
STRUCTURE: Generalized and basically
the same as other female of the genus-
Diagnostic characters that distinguish fe-

MEASUREMENTS: Comparative measurements of schizomid appendages, those
studied and those previously recorded, indicate specrfir differences, These measurements

Morpholorical data have Indirnted that
