Osteology and Phylogeny of Oviparous Cyprinodont Osteology and Phylogeny of Oviparous Cyprinodont Fishes (Order Cyprinodontiformes) By RAM PRAKASH SETHI A DISSERTATION PRESENTED TO THE GRADUATE COUNCIL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA January, I960 ACKNOWLEDGMENTS It has been a long cherished dream of mine to be able to pursue graduate studies in the United States. For making this dream come true by providing me a Graduate Assistantship, I am extremely grateful to the Biology Department and the Graduate School of the University of Florida. The assistantship not only helped me financially and academically but also enabled me to come in contact with many friendly American students with whom I had the opportunity of exchanging ideas on numerous topics. Although lacking appropriate words to express the debt of gratitude which I owe to Dr. John D. Kilby, present chairman, and to Dr. Arnold B. Grobman, ex-chairman of my committee, I wish to thank them both for constant guidance and encouragement during the course of this study. Dr. Kilby originally suggested this problem to me and always answered my numerous questions most sympathetically while Dr. Grobman constantly stimulated me to enlarge its horizons. I also wish to thank the other members of my committee, Drs. Lewis Berner, Walter Auffenberg, Ernest S. Ford, and Howard K. Wallace for numerous courtesies, continued interest in my work, and valuable encouragement. Much of the material for this study was obtained from various institutions and a number of individuals have made available specimens or information to me. For such generous help, I am deeply obliged to Drs. Curt Kosswig, Zoologisches Staatsinstitut und Zoologisches Museum, Hamburg, ¥. Germany} E. Trewavas, British Museum, London, England) ii J. L. B. Smith and R. A. Jubbs, Rhodes University, Grahamstown, South Africa} J. J. Hoederaan, Zoologisch Museum, Amsterdam, Netherlands; James E. Bohlke, Academy of Natural Sciences of Philadelphia} L. P.

Lachner, United States National Museum j William Follett, California Academy of Sciences} Clark Hubbs, University of Texas} Royal D. Suttkus, Tulane University; Caryl P. Haskins, Carnegie Institution of Washington! Donn E. Rosen, Genetics Laboratory, American Museum of Natural History; Margaret Storey and George S. Myers, Stanford University} Howard E. Evans, Cornell University} and Robert R. Miller, University of Michigan. I am also obliged to Drs. Carl L. Hubbs, Scripps Institution of Ocean- ography, and Luis Rene Rivas, University of Miami, for sending to me several papers pertinent to my problem. I am grateful to Mr. Herbert R. Axelrod, Publisher, Tropical Fish Hobbyist, for sending to me many Kodachrome transparencies of cyprinodonts as a special gift. To Drs. Robert R. Miller, Donn E. Rosen, Pierce Brodkorb, and Coleman J. Goin I am especially grateful for answering many questions about my research work and for taking continuous interest in the problems which arose. Thanks are also due to Miss Esther Coogle for help in labeling the figures which are included in this study. For encouragement, for stimulating discussion, and for numer- our courtesies, I am deeply indebted to most of the faculty and the graduate students in the Biology Department at the University of Florida. iv To the Graduate School I am grateful for financial assistance which facilitated my trip to the Genetics Laboratory of the American Museum of Natural History, to study some of the cleared and stained specimens of Dr. Donn E, Rosen and to discuss with him many problems of common Interest. This assistance also enabled me to visit the United States National Museum, where I examined material and arranged for loans. To Dr. Olive I. Reddick, Executive Secretary of the United States Educational Foundation in India, and to the Institute of International Education, Washington, I am indebted for a Fulbright Travel Grant without which my coming to the University of Florida would have been delayed considerably. I am also thankful to the Government of Uttar Pradesh, India, for a small loan for my studies abroad and to the managing committee of Agra College, Agra, India, for sanctioning a leave of absence.

A genetic and morphometric study of populations of Zoogoneticus quitzeoensis (Bean, 1898) from the Lerma and Ameca basins and Cuitzeo, Zacapu and Chapala Lakes in Central Mexico was conducted. For the genetic analysis, 7 populations were sampled and 2 monophyletic groups were identifi ed with a genetic difference of DHKY= 3.4% (3-3.8%), one being the populations from the lower Lerma basin, Ameca and Chapala Lake, and the other populations from Zacapu and Cuitzeo Lakes. For the morphometric analysis, 4 populations were sampled and 2 morphotypes identifi ed, 1 from La Luz Spring in the lower Lerma basin and the other from Zacapu and Cuitzeo Lakes drainages. Using these 2 sources of evidence, the population from La Luz is regarded as a new species Zoogoneticus purhepechus sp. nov. _The new species differs from its sister species Zoogoneticus quitzeoensis_ in having a shorter preorbital distance (Prol/SL x = 0.056, SD = 0.01), longer dorsal fi n base length (DFL/SL x = 0.18, SD = 0.03) and 13-14 rays in the dorsal fi n.

(January 2018). 1 1 Native Range and Status in the United States Native Range From Fuller (2018): “This species is confined to a very small area, the Río Ameca basin, on the Pacific Slope of western Mexico (Miller and Fitzsimons 1971).” From Goodeid Working Group (2018): “This species comes from the Pacific Slope and inhabits the Río Ameca and its tributary, the Río Teuchitlán in Jalisco. More habitats in the ichthyological [sic] closely connected Sayula valley have been detected quite recently.” Status in the United States From Fuller (2018): “Reported from Nevada. Records are more than 25 years old and the current status is not known to us. One individual was taken in November 1981 (museum specimen) and another in August 1983 from Rodgers Spring, Nevada (Courtenay and Deacon 1983, Deacon and Williams 1984). Others were seen and not collected (Courtenay, personal communication).” From Goodeid Working Group (2018): “Miller reported, that on 6 May 1982, this species was collected in Roger's Spring, Clark County, Nevada, (pers. comm. to Miller by P.J. Unmack) where it is now extirpated. It had been exposed there with several other exotic species (Deacon [and Williams] 1984).” From FAO (2018): “Status of the introduced species in the wild: Probably not established.” From Froese and Pauly (2018): “Raised commercially in Florida, U.S.A.” Means of Introductions in the United States From Fuller (2018): “Probably an aquarium release.” Remarks From Fuller (2018): “Synonyms and Other Names: butterfly goodeid.” 2 From Goodeid Working Group (2018): “Some hybridisation attempts have been undertaken with the Butterfly Splitfin to solve its relationship.

Twenty-six characters derived from comparisons of osseous structures among some aplocheiloid fi shes provided evidence supporting hypotheses of relationships among three western African genera (Callopanchax, Scriptaphyosemion and Archiaphyosemion), as proposed in recent molecular analysis. The clade comprising Callopanchax, Scriptaphyosemion and Archiaphyosemion is supported by a laterally displaced antero-proximal process of the fourth ceratobranchial. The sister group relationship between Callopanchax and Scriptaphyosemion is supported by a constriction on the posterior portion of the parasphenoid, an anterior expansion of the hyomandibula, a rectangular basihyal cartilage, an anterior pointed process on the fi rst vertebra, and a long ventrally directed hemal prezygapophysis on the preural centrum 2. Monophyly of Callopanchax is supported by a convexity on the dorsal margin of the opercle, a long interarcual cartilage, and long neural prezygapophyses on the anterior caudal vertebrae. > Key words Killifi shes, Callopanchax, Africa, Osteology, Annual fi shes.
