Through the courtesy of Dr. Johann
. Becker, entomologist in the National Mu: seum at Rio de Janeiro, I have been able to
; study in the present paper a small lot of
; Opiliones collected in Pogos de Caldas, State
: of Minas Gerais, Brazil. The town of Pogos
i de Caldas is situated in a region of great
; radioactivity, and this is the reason why the
' present work was partially sponsored by the
:.u. S . Atomic Energy Commission.
The majority of the specimens reported
. on are the results of the collecting efforts
of Dr. Johann Becker.
The collection I have at hand, consisting
· almost exclusively of Opiliones of the family
, Gonyleptidae, though small, is an interesting
one. Only one specimen of the female sex
of the family Phalangodidae was sent, so I
· decided ·to study it on another opportunity,
' when more representative material is avail. able.
As to the records of the species, I will
refer only to the localities within Pogos de
Caldas, avoiding to repeat frequently the
town name.
All examples, including the types, are
deposited in the arachnological collection of
the National Museum at Rio de Janeiro,

Subfamily Pachylinae
Beckeresia g. n.
Eye tubercle with a median high spine
directed upwards and forwards. First, se·
cond and fifth areas without median armature, third with a pair of tubercles, fourth
with a very robust conical median apophysis
in the male .. First area with a median line.
First, second and third free tergites, femora
of palpi and anal operculum without median
armature. Tarsal segments: 5-6-6-6. Basitarsus of first tarsus not enlarged.
Type-species: Beckeresia beckeri sp. n.
Beckeresia notwithstanding its rounded
form and the presence of a strong forwards
directed spine on the front margin of the
cephalothorax, seems, according to the armature, to be more related to Berlaia MelloLeitao, 1940: 9, from which it differs by having the third free tergite unarmed and the
fourth area with a very robust conical median apophysis. In Berlaia boj;h the third free
tergit and the fourth area (in the male and
in the female sex) have a median spine.
Both Beckeresia and Berlaia have rounded
bodies, but in this respect they differ in their
shapes.

Eopachyloides g. n.
Eye tubercle with a median spine directed upwards and forwards. First area with
a median line (rarely without a median
line). First, second and fifth areae without
median armature, third with a pair of blunt
apophyses in the male, unarmed in the female, fourth with a pair of broad, low and
elongate tubercles in the male. Free tergites,
femora of palpi and anal operculum unarmed. Tarsal segments: 5-6-6-6. Distitarsus of
first tarsus not erilarged.
Type-species: Eopachyloides trochanteralis sp. n.
This genus, according to the exhibited
characters, appears to be very closely related
to Eopachylus Mello-Leitao, 1931: 94, from
which it differs: 1st - by the third area
which instead of pair of spines has in the
male two large blunt apophyses; 2nd - by
the presence of two median broad, low and
elongate tubercles in the fourth area in the
male; 3rd -by the not enlarged distitarsus
of first tarsus. The female could be easily
taken by a Progyndes Roewer, 1916: 107,
·but in the latter the third area is unarmed
even in the male.

spine on each side near the angles. Eye tubercle marginal, high, with a high spine directed upwards and forwards. Cephalothorax
with rare minute piliferous granules on the
hind portion (these granules are only visible
when the material is slightly wet with
alcohol). First area very long with a median
longitudinal line that can be seen when the
area is. slightly wet with alcohol. First, second and fifth areae unarmed, first and second with minute granules irregularly distributed. Third area with a pair of strong
granulate blunt divergent apophyses and
minute scattered granules. Fourth area with
two low and elongate median tubercles as
long as the area and provided with small
granules. Fifth area and free tergites with a
row of piliferou:s polished granules. Lateral
margins of the abdominal scute with two
rows of small granules, those of the outer
row larger and polished at the level of the
second area. Anal operculum unarmed,
granulate. Free sternites with a row of minute hair-tipped granules. First and second
coxae with acute piliferous granules, third
coxae with minute hair-tipped granulations.
Palpi small: trochanteres with a low ventral
piliferous tubercle; femora unarmed with
two ventral piliferous granules (one basal
another submedian); tibiae with 3-3 and tarsi
with 3-4 ventral spines. First legs granulate:
femora substraight and tibiae with a
ventral outer row of tubercles. Second legs
granulate. Third legs granulate, the femora
and tibiae with two ventral rows of small
spines (those of the tibiae stronger and larger). Fourth legs: coxae with minute hair-tipped-granulations irregularly distributed,
