Abstract
A critical descriptive revision of New World spp. of the subgenera Diagyne; Solenopsis; EUOPHTHALMA (p. 43), type Myrmica globularia Fred. Smith; and OEDALEOCERUS (p. 43), type Solenopsis angulata Emery; with a key to these subgenera and keys to the spp. in each. S. (S.) bondari*, redescribed; S. gayi and var. fazi, figured; S. g. ssp. bruesi* (p. 52), Peru; S. geminata* (=S. g. var. nigra Forel), a typically West Indian sp., key to subspp., redescription of forms; S. g. ssp. rufa* (Jerdon.) (=S. g. var. diabola Wheeler); S. g. ssp. eduardi* (S. e. Forel,[long dash]S. e. var. perversa Santschi) (p. 67); S. g. ssp. medusa* Mann ( = S. eduardi v. bahiaensis Sant.) ; S. saevissima* (F. Smith) (=. moelleri v. gracilior Forel), key to vars.; S. s. var. moelleri (S. m. Forel, =S. geminatus v. incrassata Forel, S. saevissima v. morosa Sant., S. s. var. pylades Sant.) (p. 83) ; S. s. var. richteri Forel ( = S. pylades v. tricuspis Forel) ; S. s. ssp. interrupta* Sant. ( = S. s. var. macdonaghi Sant.) ; S. s. ssp. electra*; S. xyloni* Mac Cook, key to vars. Under the subg. Euophthalma are arranged the following: S. andina*; S. globularia* ( = S. g. ssp. lucayensis v. curta Forel) ; S. g. ssp. littoralis* (p. 113), Alabama (type) and Mississippi; S. g. ssp. steinheili Forel (= S. g. var. borinquenensis Wheeler, S. g. var. cubaensis Wheeler) ; S. huachucana*; S. macrops*; S. metanotalis*, redescribed; S. m. ssp. shiptoni* (S. s. Forel) (p. 127) ; S. nigella*, redescribed; S. n. ssp. gensterblumi* (S. picta ssp. g. Forel, =S. n. ssp. praeva-lens Sant.) (p. 132); S. oculata*; S. silvestrii*, redescribed. In subg. Diagyne, S. succinea Emery ( = S. inermiceps Wheeler & Mann). Subg. Oedaleocerus is confined to S. angulata*. The distribution of the species shows that 20% are peculiar to North America, 20% are indeterminate, occurring either in the Antilles or Central America or ranging over both continents, and 60% are indigenous to South America. The author favors the Antillean origin of the group.
