Ackertia globulosa sp. n. (Nematoda: Filarioidea) from rodents in Kenya.

Ackertia globulosa sp. n. (Nematoda: Filarioidea) is described from the pulmonary arteries of the striped mouse, Lemniscomys striatus striatus (L.), in Kenya. Distinguishing features are the small size of the adults; the short left spicule and arrangement of the caudal papillae (3 pairs preanal, 4 pairs postanal) of the male; small projecting lobes on the tail of the females; and 10 to 12 refractile globules in the microfilarial sheath. The microfilariae are found in the skin, mostly of the ear. The probable intermediate host is a hard tick, Haemaphysalis leachi.     

Dunnifilaria dilli sp. n. (Nematoda: Filarioidea) from Rattus koratensis in Thailand.

Dunnifilaria dilli, a new species of filariid from Rattus koratensis from Thailand is described. Adult worms were recovered from the lymphatic system. They differ from D. ramachandrani in their location in the host, the tail length, the shape of the spicules, and in the number of caudal papillae. Microfilariae are much smaller and unsheathed. Additional hosts include R. rattus and R. sabanus.     

Dirofilaria cancrivori sp. n. (Nematoda: Filarioidea from the crabdog, Procyon cancrivorus, in Guyana

Dirofilaria cancrivori sp. n. is described from subcutaneous tissues of the crabdog, Procyon cancrivorus, in Guyana, South America. The filarid is morphologically distinct from Dirofilaria tenuis, parasite of a related host, the raccoon, in the southern United States, and all other species of Dirofilaria. The parasite can be distinguished from other dirofilarias based on a combination of morphological features including its size, number, and arrangement of caudal papillae on the male tail, size and shape of the spicules, the presence of longitudinal ridges and transverse striations on the cuticle, and the microfilaria.     

Tetrapeltalonema (t.) mystaxi sp. n. (Nematoda: Filarioidea) from Brazilian moustached marmosets, Saguinus m. mystax.

Tetrapetalonema (T.) mystaxi sp. n. is described from the subscapular connective tissues of Saguinus mystax. The parasite is placed in the subgenus Tetrapetalonema and most closely resembles Tetrapetalonema atelensis, from which it can be differentiated by its long esophagus, size and shape of the spicules, and the size and arrangement of nuclei in the tail of the microfilaria.     

Mylonchulus sessus n.sp. (Nematoda: Mononchida) from Brunei

Summary Mylonchulus sessus n.sp. is described. It is close to M. sigmaturus and M. dentatus and was found in soil from around tomato from Brunei. It has an exceptionally well developed and differentiated female reproductive system which is rather unusual in Mylonchulus and, although close to M. sigmaturus and M. dentatus differs from both in having wider amphids and smaller submedian teeth.     

Trichodorus persicus n. sp. (Nematoda: Trichodoridae) from Iran

Trichodorus persicus n. sp. is described from the Caspian region of Iran, where it was found in woodland and orchard soil. Males of the new species usually have two ventral cervical papillae anterior to the excretory pore but posterior to the base of the onchiostyle; there are three ventromedian preanal supplements, the posterior one lying near the heads of the retracted spicules; the spicules are 51–61 m long with faint transverse striations distally. Females have two pairs of lateral body pores, large rounded sclerotized thickenings at the vulva and the vagina tapers inwards in lateral view.     

Xiphinema bacaniboia n.sp. (Nematoda: Dorylaimida) from Fiji

Summary Xiphinema bacaniboia n.sp. is described from rain forest in Fiji. Adult females are characterized by their spiral shape on heat death, slightly offset lip region, total stylet length of 270–292 m, post-median vulva, paired, opposed genital branches with greater development of the anterior one, absence of a Z organ and the presence of a broadly rounded tail, flattened ventrally with no blind canal. The species is differentiated from X. ingens Luc & Dalmasso, 1964, X. macrostylum Esser, 1966 and X. riocaquetae Hunt, 1982. ac]19830610     

Coslenchus capsici n. sp. (Nematoda: Tylenchidae) from India

Coslenchus capsici n. sp., from around the roots of Capsicum annuum at Kulu (H.P.), India, is characterized by a large number of cuticular ridges (17+17 + lateral fields), a smooth head with a well-sclerotized framework and a forwardly inclined vagina with swollen walls.     

Criconemella anastomoides n. sp. (Nematoda: Criconematina) from Pakistan

Criconemella anastomoides, described and illustrated herein, is characterized by the presence of regular anastomosis on the body, two zig zag lateral lines, stylet knobs sloping posteriorly, short stylet, and short body length.     

Acanthocheilonema delicata n. sp. (Nematoda: Filarioidea) from Japanese badgers (Meles anakuma): Description,molecular identification,and Wolbachia screening

Acanthocheilonema delicata n. sp. (Filarioidea: Onchocercidae: Onchocercinae) is described based on adult filarioids and microfilariae obtained from subcutaneous connective tissues and skin, respectively, of Japanese badgers (Meles anakuma) in Wakayama Prefecture, Japan. No endemic species of the genus had been found in Japan. Recently, some filarioids (e.g., Acanthocheilonema reconditum, Dirofilaria spp., and Onchocerca spp.) have come to light as causative agents of zoonosis worldwide. The new species was readily distinguished from its congeners by morphologic characteristics such as body length, body width, esophagus length, spicule length, and the length of microfilariae. Based on the molecular data of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene, A. delicata n. sp. was included in the clade of the genus Acanthocheilonema but differed from two other congeneric species available for study, A. viteae and A. reconditum. Acanthocheilonema delicata n. sp. did not harbor Wolbachia. It is likely that the fauna of filarioids from mammals on the Japanese islands is characterized by a high level of endemicity.     

Panagrellus ceylonensis n. sp. (Nematoda: Cephalobidae)

Panagrellus ceylonensis n. sp. is described from rubber latex in Ceylon. Its long, slender spicules are curved ventrally with a dorsal deflection at two-thirds of their length. The manubrium is thick and hooked, and the shaft is not widened at the shoulder. The terminal bifurcations are wide, with the dorsal one considerably longer and thicker than the ventral. The main ventral element is continuous with the terminal sheath with the ventral bifurcation arising within it.     

Halalaimus algeriensis n. sp. (Nematoda) from the Sahara

During a trans-Saharan expedition in 1980 a number of samples were collected from stagnant and running fresh and slightly saline water bodies. One of them, collected from the Oued En-Namous in a small oasis yielded several interesting nematodes, among which was a newHalalaimus species described herein asHalalaimus algeriensis n. sp. It comes close toH. minusculus Tchesunov, 1978, but differs in tailshape, absence of males and habitat. It also resembles the marine speciesH. gracilis de Man, 1888, but differs in the relative length of the anterior setae, the absence of a lateral field and absence of males. The new species can be differentiated fromH. stammeri Schneider, 1940, the only fresh water species found hitherto, by its shorter body, more anterior and wider fovea, and the length and position of the anterior setae. The various juvenile stages can be separated on the basis of body length, foveal length and genital primordium.
