PROC. BIOL. SOC. WASH. 95(1), 1982, pp. 81-88 A NEW DWARF SPHAERODACTYLUS FROM HAITI (LACERTILIA: GEKKONIDAE) Richard Thomas Abstract. — Sphaerodactylus omoglaux is described from the southeastern Cul-de-Sac Plain and adjacent montane foothills of Haiti. It is a ground dwelling species of xeric to semi-xeric situations and belongs to a group of Hispaniolan Sphaerodactylus including S. altavelensis Noble and Hassler, S. armstrongi No-ble and Hassler, S. cryphius Thomas and Schwartz, S. darlingtoni Shreve, S. nycteropus Thomas and Schwartz, and S. streptophorus Thomas and Schwartz. Recent fieldwork in Haiti resulted in the discovery of an undescribed small species of Sphaerodactylus in the southeastern part of the Cul-de-Sac Plain and adjacent foothills of the Massif de la Selle. This new sphaerodactyl is related to the recently described Sphaerodactylus cryphius and S. streptophorus (Thomas and Schwartz, 1977). Abbreviations. — ASFS refers to the Albert Schwartz Field Series, CM to the Carnegie Museum of Natural History, RT to Richard Thomas's personal collec-tion, UMMZ to the University of Michigan Museum of Zoology, and USNM to the National Museum of Natural History.
