Infective third-stage larvae of Dipetalonema viteae (Nematoda: Filarioidea) were cultured to young adults in a cell-free culture system. Third-stage larvae from the tick vector grew, developed, and molted twice in a medium containing NCTC 135 and Iscove's modified Dulbecco's medium supplemented with fetal bovine serum under a gas phase of 95 percent nitrogen and 5 percent carbon dioxide. The availability of such a culture system for filariids should facilitate studies of their immunology, biochemistry, and sensitivity to drugs.

A 21-mm filarial worm appeared suddenly in the anterior chamber of the right eye of a 32-year-old man in western Oregon. By a simultaneous irrigation-aspiration procedure, it was removed alive and only slightly damaged and was identified as a female Dipetalonema in the fourth stage of development. It was the third such case to be reported from western Oregon. In this and one other case the worms were morphologically similar to adult worms identified as Dipetalonema arbuta Highby 1943 from the body cavity of the porcupine (Erethizon dorsatum) and a similar species, Dipetalonema sprenti Anderson 1953, from the body cavity of the beaver (Castor canadensis).

Dipetalonema (Acanthocheilonema) didelphis sp. n. recovered from the subcutaneous and periesophageal connective tissues of Didelphis virginiana from several localities in the United States and of D. marsupialis from Colombia is described. Dipetalonema didelphis sp. n. resembles D reconditum and D. mansonbahri in size, in lacking a two-segmented buccal capsule, and in the female having a long, digitiform tail. Dipetalonema reconditum, however, has a much longer glandular esophagus and D. mansonbahri has a rounded cephalic extremity delimited by a necklike region. The male of D. didelphis sp. n. differs from both in the structural details of the spicules and in having a higher spicular ratio. The microfilaria is much shorter than that of either D. reconditum or D. mansonbahri. Dipetalonema (A.) pricei adults are redescribed from the paratype specimens, and the microfilaria is also described. Dipetalonema pricei most closely resembles D. dracunculoides in size and in the presence of a well-developed, two-segmented buccal capsule, but the latter species has a much longer glandular esophagus. These two species also differ in the appearance of the spicules.

The clinical and pathologic effects of the filarioid nematode Dipetalonema spirocauda were studied in the harbor seal, Phoca vitulina concolor. Aberrant behavior of both adults and microfilariae resulted in previously unreported pulmonary, vascular and hepatic lesions.

Review
Fifty-six cases of human intraocular filariasis have been reported. In 6, the objects interpreted as filariae may have been artifacts. In 8, a motile worm that apparently was not a filaria was observed. In the remainder, a motile filaria or filaria-like worm was observed, but in only 6 cases were the filariae removed from the eye, described, and identified. Three of these were identified as Dipetalonema spp., and one each as Wuchereria, Dirofilaria, and Loaina. In 10 cases, filariae were removed and identified as Loa loa (6) or Wuchereria bancrofti (4) but without a supporting description. A filaria was removed but not satisfactorily described or identified in 8 cases, spontaneously disappeared in 4, died following treatment in 4, and met unreported fates in seven. For 3 the original reports were inaccessible. Records of intraocular filariae that are not supported by morphological description are questionable.

Through comparing the morphological evolution to the host range and the geographical distribution we can suggest Dipetalonema sensu-largo may be interpreted as a gondwanian lineage which may have evolved after the three main austral continents drifted apart. Therefore, we propose the following systematic splitting: --Sprattia n.gen., type species: S. venacavincola parasite of Australian Marsupials, which may be related to Litomosa; --Breinlia Yorke and Maplestone, 1926, and Breinlia (Johnstonema) (Yeh, 1957), parasite of Australian Marsupials; --Skrjabinofilaria (Travassos, 1925), parasite of American Marsupials; --Macdonaldius (Khanna, 1933), parasite of American Reptiles; --Dipetalonema (Orihelia) n.sub. gen., type species: D. (O.) anticlava, parasite of Dasypodidae; --Dipetalonema (Acanthocheilonema) (Cobbold, 1870), parasite of Insectivora, Carnivora, Pinnipedia, sometimes Rodents; --Dipetalonema (Molinema) (Freitas and Lent, 1939), parasite of Caviomorpha and Beavers; --Dipetalonema (Loxodontofilaria) (Berghe and Gillain, 1939), parasite of Ethiopian Ungulates; --Dipetalonema (Chenofilaria) (Kou, 1958), parasite of Asiatic Pholidota and Australian Marsupials; --Dipetalonema (Dipetalonema) (Diesing, 1861), parasite of American Primates; --Monanema Anteson, 1968, parasite of Rodents other than Cariomorpha; --Ackertia (Vaz, 1934), parasite of Caviomorpha; --Tetrapetalonema (Sandnema) n.sub.gen., type species: T. (S.) digitata, parasite of Asiatic Insectivora and Primates; --Tetrapetalonema (Tetrapetalonema) (Faust, 1935), parasite of Tupaidae, Platyrhinii, and, sometimes, American Rodents and Carnivora; --Tetrapetalonema (Esslingeria) n. sub.gen., type species: T. (E.) perstans, parasite of African African Anthropoidea and Humans; --Filarissima (Chabaud, 1974), parasite of Caviomorpha.

Dipetalonema gracile (Rudolphi, 1809) (Filarioidea: Onchocercidae) is one of six species of cavities filarial parasites of Neotropical non-human primates. The present study recorded the occurrence of D. gracile, provides morphological and morphometric data and extends the geographical distribution. Adult filariae were obtained from the thoracic and abdominal cavities of 38 specimens of woolly monkey, which were used for local human consumption, in the northeastern Peruvian Amazon. Male and female filarids were processed and analysed using light and scanning electron microscopy. Details of the cephalic papillae, post-cloacal bands and papillae, vulva, phasmid position and lateral appendages are showed by scanning electron microscopy and is recorded the occurrencce of Lagothrix poeppigii monkey as a new host of this filaria in the Yavari-Mirin river basin, Peruvian Amazon.
