A NEW KOHLSIA FROM THE REPUBLIC OF COLOMBIA (SIPHONAPTERA: CERATOPHYLLIDAE) EusTORGio Mendez Gorgas Memorial Laboratory, Apartado 6991, Panama 5, Republic of Panama Henry Hanssen Departamento de Microbiologia, Facultad de Medicina, Universidad do Antioquia, Medellin Colombia ABSTRACT — Description and illustrations of Kohlsia falcata Mendez and Hanssen, n. sp. are given. This species is compared with K. tiptcmi Mendez and Altman, its nearest known relative. The new species of Kohhia described in this paper represents the first record of the genus for the RepubHc of Colom1)ia. Another South American species, K. campaniger (Jordan), was described from Ecua-dor. Presently, the known range of Kohhia seems to extend from Mexico, throughout Central America and Panama to areas of Colombia and Ecuador in northwestern South America. Tipton and Machado-Allison (1972) present no record of Kohlsia from Venezuela. How-ever, it is possible that this genus is extant also in that country. Kohlsia falcata Mendez and Hanssen, new species Fig. 1-8 Type material: S Holotype, 9 allotype and 1 S paratype, ex Tamandua tetradactijla Linnaeus, Hacienda "La Concjuista" (humid tropical forest, elevation 642 m), 70 km North of Puerto Lopez, De-partmento del Meta, Colombia, July 1971, H. Hanssen, collector. Holotype and allotype deposited in the U.S. National Museum of Natural History. Paratype in the British Museum (Natural History). Length of types (in mm): <5 Holotype, 1.95, 9 allotype, 2.00; i paratype, 1.87. Diagnosis: Kohhia falcata, n. sp. is similar to K. tiptoni in several morphological features. Two of the most outstanding of these are the tibial comb, found on all legs, and the possession of a prominent bristle on the dorsal margin of the distal arm of the ninth sternum. It is readily separated from the latter species and from all other known Kohhia by the peculiar primary dorsal lobe of the aedeagus, which is definitely sickle-shaped. A squamose area of the aedeagal alate lobe also seems to be pecuHar to the present new species. MALE: Head (fig. 1): Anterior margin provided with short frontal tubercle. Preantennal area with numerous micropores, 3 rows of prominent bristles and several scattered minute bristles. Postantennal area having few micropores and 3 rows of unequal bristles. Both pre-and postantennal areas showing typical 91
