TULANE STUDIES IN ZOOLOGY Volume 14, No. 1 APR 1 9 1967 HARVARD UNIVERSITY April 6, 1967 THE LEIOCEPHALUS ( LACERTILIA, IGUANIDAE) OF HISPANIOLA 11. THE LEIOCEPHALUS PERSONATUS COMPLEX. ALBERT SCHWARTZ 10000 SW Hh St., Miami, Florida Abstract Examination of 1240 specimens of Leiocephulns from Hispaniola revealed that the species L. personatus Cope is actually composed of four species : 1 ) L. personatns, with its subspecies per-sunatns (north shore of the Tiburon Peninsula), trujilloensis (vicinity of Santo Domingo), mentalis (extreme eastern Republica Dominicana), tara-chodes (north and south of the Bahia de Samana and including the Peninsula de Samana), actites (northern coast of Republica Dominicana), scalaris ( northern Hispaniola, from Cap-Hai-tien in Haiti east through the Valle de Cibao in Republica Dominicana), budeni (northern slope of Cordillera Central at intermediate elevations), and agraulns (uplands of Cordillera Central near Constanza and southern slopes of same range) ; 2) L. lunatns, with its subspecies lioiatus (southeast-ern Dominican coast near Santo Do-mingo), ayeiiicolor (southeastern Do-minican coast from San Pedro de Ma-coris to Boca Chavon), thomasi (vicin-ity of Boca de Yuma), melaenacelis (Isla Catalina), lonisae (Isla Saona) ; 3) L. barahonensis with its subspecies ba}-ahoriensis (northern and eastern foothills of Sierra de Baoruco), uxy-y aster (Peninsula de Barahona), a»-rens (southern Haiti from Jacmel east into southern Republica Dominicana near Pedernales), beatanns (Isla Bea-ta) ; 4) L. vinculmn with its subspecies vinculum (He de la Gonave), endu-mychus (interior Haiti), altavalensis (Isla Alto Velo). The status of L. eremitus (Navassa Island) is discussed and this species is considered distinct from any Hispaniolan species. A his-tory of the personatns complex is pre-sented and comparisons of the Leioce-phalus faunas of the Antilles are made; Hispaniola is shown to have the greatest diversity of species, none of which shows any obvious relationship to the Cuban Leiocephalus. Introduction Of the five species of the lizard ^enus Leiocephalus occurring on Hispaniola, L. personatns Cope, 1862, is the most widely distributed. The description was based upon two syntypes from near Jeremie, Departe-ment du Sud, Haiti, near the tip of the Tiburon Peninsula. In the same paper, Cope also described "Liocephalus trigemina-tiis", also from near Jeremie; presumably (the type cannot presently be found) this description was based upon a female of L, personatns, since the description includes notes on the dorsal pattern and coloration which agree with females rather than with males of that species. No further names w^ere proposed for this group of lizards until barahonensis Schmidt, 1921, from the western portion of the Republica Domini-cana, and this was followed by beatanns Noble, 1923, from Isla Beata and vincnlnm Cochran, 1928, from He de la Gonave. Dur-ing the next decade, the populations from the northern portion of Hispaniola {scalaris Cochran and mentalis Cochran, 1932), from Isla Alto Velo {altavelensis Noble and Hass-ier, 1933), southern Haiti {anrens Cochran, 1934), southern Republica Dominicana {Innatns Cochran, 1934) and Isla Saona Editorial Committee for this Paper: Richard Etheridge, Division of Life Sciences, San Diego State College, San Diego, California Ernest Williams, Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts
