• A New Killifish From the Congo In March of this year a friend of mine whose sister is married to a Protestant minister in Brazzaville, Congo, went to visit them for four months. Though he is an aquarist, he didn’t think of taking fish with him on the way back. Therefore, I decided to write to him and ask him to look around for fish, requesting him to take everything he could get, especially killifishes. As he didn’t answer, I did not know what to expect. Then came a telegram advising me of his return trip. The day came and I was eagerly awaiting but I was a little disappointed when he arrived with just one small plastic sack. There were not more than ten fish in it. After a few days in my tanks, I concluded that there sure was something new there! Six of them were a fish very close to Aphyosemion roloffi, most likely that fish. They were divided into 4 males and 2 females. The other 4 remaining fish were a mystery, however. There was 1 male and 3 females and after looking through various books and talking to my friend, Alfred Radda, I still didn’t know what they were. This fish resembles more a Nothobranchius than an Aphyosemion, something like our Aphyosemion walkeri. The females are very close to those of walkeri and hardly differ. The only difference is a light, reddish coloration in the dorsal, anal and caudal fins. In all other aspects, including also the small red dots on the body, the female is hard to tell from one of walkeri. The coloration of the male differs from walkeri although there is a little similarity. The whole body is more greenish than blue, and on the belly, the green changes into a dark-orange. All fins are bright-yellow with reddish, sometimes wormlike, dots and lines. The dorsal, anal and caudal fins are dark-red or often black- bordered. The caudal fin doesn’t have filaments such as does wal- keri, but is more like one of Aphyosemion gardneri or better still, Aphyosemion coeruleum. The length of the male is about

• A NEW SPECIES OF APHYOSEMION (TELEOSTOMI: CYPRINODONTIDAE: RIVULINAE) FROM GHANA, AND A REDEFINITION OF SUBGENUS FUNDULOPANCHAX MYERS, 1924. Akosombo1 and David Blair Glasgow2 Aphyos!'mion seymouri sp. nov., an annual cyprinodontid from the Accra Plains of Ghana, is described. Data on habitat, ecology, range and life history are presented. Affini ties with other rivulins are considered. Major evolutionary lines within the subgenus Fundulopanchax Myers sensu lulu are discussed. This subgenus is considered to include only Aphyosemion sjoestedti Lonnberg, A. gulare Blgr., an undescribed species from Meko in Western Nigeria, and A. seymouri sp. nov. Stenholt-Clausen (1967) defined the range of Aphyosemion as east of the Togo-Dahomey gap (the western boundary of this zone of in trusive savannah is taken as the Volta River) with the e�ception of Aphyosemion walkeri (Blgr., 191 1) described from the rain - forest isolate in Western Ghana. In June 1968, one of us (DB) collected a Nothobranchius-like rivulin from a small temporary pool in the Accra Plains, 55 miles east of Accra, the capital of Ghana. A few fish were sent to the United Kingdom in 1968 and 1969 and introduced to killi fish hobbyists as Aphyosemion BKA- U 1. Some of this material was also sent to Colonel J. J. Scheel for study. On the basis of cephalic squamation and egg type, Scheel (in litt.) identified the fish as an Aphyosemion and recognized it as an undescribed species. The laboratory work for this description was undertaken by the senior author while the second author provided range data and ob servations on the fish's biology and furnished the specimens of the type series. DESCRIPTION - Aphyosemion seymouri sp. nov. (Fig. 1 ) Holotype: Adult male 34.0 mm standard length captured in a small temporary pool several dozen yards south of the Accra-Ada Road at a point midway between Mile 5 4 and Mile 55 markers, Accra Plains, 1 Volta Lake Research Project
