a previous paper (Levi 1957b). In this paper the ventral view of the 
genitalia (cleared epigynum) was illustrated, not the dorsal as in 
most of my papers on theridiid spiders. Gertsch (i960) has taken 
issue with my treatment of species of the “fulva” group in the previous 
paper and has named several new species. However, insufficient 
ecological and life history data are available for the possible species 
involved to permit making a final decision now (Levi, i960). Thus 
the only species recognized are those of my previous revision. 
Steatoda brasiliana Keyserling, 1884, Die Spinnen Amerikas 
Theridiidae, 2(1) : 115, pi. 5, fig. 75, cf . Male type from Rio de 
Janeiro, Brazil in the Naturhistorisches Museum, Vienna, examined 
is a male Steatoda bipunctata (Linn.) from Europe (NEW SYN- 
ONYMY). The female described by Keyserling in 1886 as S. 
brasiliana is probably a specimen of S. inoesta (Keyserling). 
Species misplaced : Lithyphantes juninensis Keyserling— Enoplog- 
natha juninensis (Keyserling). 
Steatoda rubra Keyserling, 1886, Die Spinnen Amerikas, Theri- 
diidae, 2(2) : 239, pi. 20, fig. 294, $. Female type from Blumenau, 
Brazil — — T heridion rubra (Keyserling). 
Key to American Species of Steatoda 
1 a. Epigynum with a prominent, wide, transverse bridge; areas 
anterior and posterior to bridge shallow depressions (1957b, 
figs. 43, 44, 46, 47, 49, 50) ; palpus with thread-like embolus 
on venter, evenly curved, with a membrane inside embolus loop 
from base supporting a portion of embolus (1957b, figs. 32-41) ; 
North America S. fulva group 
ib. Epigynum without transverse bridge or if with bridge, then 
areas anterior and posterior to' it not depressed ; embolus other- 
wise or if similar South American 2 
2a. Seminal receptacles thickened, sclerotized, coiled ends of ducts 
(1957b, figs. 88, 92, 98, 1 16); epigynum having a U-shaped 
depression (1957b, figs. 105, 107-109) or a shallow circular 
depression containing anterior a deeper depression on each side 
of a septum (rarely absent) (1957b, figs. 93, 97, 99-103) or 
epigynum as in 1957b, fig. 89; palpus with a prominent U- 
shaped radix on mesal side (1957b, figs. 119, 124, 129, 134, 
145, 155) ; North America S. bipunctata group
