mm wide. First patella and tibia missing; second, 2.3 mm; third, 
1.7 mm; fourth, 2.5 mm.

Theridion myersi Levi 
Theridion myersi Levi, 1957, Bull. Amer. Mus. Natur. Hist. 112: 31, figs. 
95-98, $ $. Male holotype from Fort Myers, Lee Co., Florida, in the 
American Museum of Natural History. 
This rare species was known only from Florida; Monterrey 5 Nueva 
Leon; Tamaulipas and Ixtepex, Oaxaca, Mexico, without informa- 
tion about its habitat. I collected an adult male under coral stones 
on the side of the highway. 18.III.1964, on Bahia Honda Key, 
Monroe Co., Florida. 
Theridion melanosternum Mello-Leitao, emend.* 
Figures 9-12 
Theridion melanosternon Mello-Leitao, 1947, Arq. Mus. Paranaense 4: 237, 
figs. 4, 5 $. Female holotype from Bariqui, Curitiba, Brazil in the 
Inst. Defeso do Patrimonio Natural in Curitiba, examined by M. E. 
Galiano in 1968. 
The types of the species were deposited in the Museu Paranaense. 
The museum no longer exists and the specimens are now kept in the 
Instituto de Defeso do Patrimonio Natural, Secretaria de Est. dos 
Negocios da Agricultura, Curitiba, Parana, Brazil. It was never 
possible for me to examine the specimen. Miss Maria Elena Galiano 
paid a visit to this institution and made drawings for me of the type 
of Theridion melanosternum. The specimen is labeled Theridium 
nigristerni. Mello-Leitao gave total length 3.6 mm, and first patella 
and tibia 4.7 mm. The long legs and epigynum (Fig. 10-11 ) resemble 
those of Theridion longipedatum Roewer (-T. longipes Keyserling) , 
described from Santa Fe de Bogota (a locality where the specimen 
presumably was bought or traded and not where it was found). 
However the measurements Keyserling gives are total lengthy 5.3 mm 
and first patella and tibia, 5.2 mm.
