Monanema australis Spratt 2008
No full textMonanema australis Spratt, 2008 Monanema australis Spratt, 2008 pp. 1–6, Figs. 1–9, from Melomys cervinipes and Uromys caudimaculatus Severin Ck., Danbulla State Forest, north Queensland. Type host. Melomys cervinipes (Eutheria: Muridae). Other hosts. Melomys burtoni (Ramsay), Uromys caudimaculatus (Eutheria: Muridae). Site in host. Lung parenchyma, hepatic blood vessels and lymphatics. Distribution and hosts. Monanema australis is known from the original description from the lung parenchyma of the fawn-footed melomys and from hepatic blood vessels and lymphatics of the giant white-tailed rat on the Atherton Tablelands, north Queensland. It appears also to be known from the note and illustration by Mackerras (1962) of unidentified, sheathed microfilariae from the blood of Melomys cervinipes, M. burtoni (as M. lutillus litoralis (Thomas, 1913)) and U. caudimaculatus in the Inisfail region of north Queensland. Remarks. This is the only species of Monanema described from Australian hosts, the other four species of the genus occurring in sciurids in North America and murids in the Ethiopian region. Ixodid ticks act as intermediate hosts and vectors of the three species for which life cycles are known (Ko 1972; Bianco & Muller 1977, Bianco et al. 1983, Petit et al. 1988), with microfilariae occurring in the small lymphatic vessels of the skin. Spratt (2008) also noted a much larger, sheathed microfilaria from the blood of Mesembriomys gouldii (Gray) from Mareeba airport on the Atherton Tablelands, possibly representing an undescribed species of Monanema in this murid host.Published as part of Spratt, David M., 2011, New records of filarioid nematodes (Nematoda: Filarioidea) parasitic in Australasian monotremes, marsupials and murids, with descriptions of nine new species 2860, pp. 1-61 in Zootaxa 2860 (1) on page 47, DOI: 10.11646/zootaxa.2860.1.1, http://zenodo.org/record/528650

No full textTranscript of a letter by an unidentified author to David Fentress regarding sharing federal newspapers and the banning of federal newspapers in some areas. The author passes on the news of the war including the destruction of the Federal merchantmen by the Confederate fleet.

Breinlia (Breinlia) oweni Spratt 2011, sp. nov.
No full textBreinlia (Breinlia) oweni sp. nov. (Figs 38–47) Type host. Dactylopsila trivirgata Gray (Marsupialia: Petauridae). Site in host. Peritoneal cavity. Material examined. Holotype: ♂, from Dactylopsila trivirgata, Balamuk, Western Province, Papua New Guinea (08 0 55’S, 141 0 17’E), coll: I. Owen, December,1988, AHC 45861, allotype: ♀, AHC 45862; paratypes: 2♂, AHC 45863; 3♂, QM G232521; 1♀, 4♀ anterior and posterior fragments, AHC 45864, 1♀, 1♀ anterior and posterior fragments QM G232520; 1♂ broken, ♂ and ♀ fragments (N3069). Etymology. The species is named after Mr. Ifor Owen who collected the material and who has been, for several decades, a diligent collector of parasites from wildlife in Papua New Guinea. Differential diagnosis. Breinlia (Breinlia) oweni is most similar to B. (B.) mackerrasae from short–nosed bandicoots in eastern Australia and B. (B.) presidentei from murid rodents in northwest Western Australia. It is distinguished from the former by much shorter males and females, shorter right spicule, much longer filament of left spicule (0.21 vs 0.13 as measured from Fig. 2 of Walker and MacMillan, 1974), fewer post–cloacal papillae and none located close to posterior extremity, shorter muscular oesophagus and tail in males, more anterior position of vulva, much shorter tail and shorter muscular and glandular oesophagus in females. It is distinguished from B. (B.) presidentei by slightly shorter males and much shorter females, presence of rectangular rather than square peribuccal fields in apical view of cephalic end, shorter right spicule and muscular oesophagus in males and much shorter tail in females, the tail tip in both sexes terminating in a pair of latero–ventral papillae and a median papilla. Description. General: Moderately long nematodes with posterior extremity more attenuated than anterior. Oral opening small, round, bounded by delicate membrane. Four pairs of submedian papillae arranged in outer circle of four large and inner circle of four smaller papillae. Rectanglar, cuticular, peribuccal field present, joining bases of papillae of inner circle. Second, less conspicuous, rectangular peribuccal field present, formed by slight elevation of cuticle joining bases of papillae of outer circle. Internolateral papillae absent. Amphids large, lateral, opening at level between two circles of papillae. Buccal capsule small, narrow, with small, refractile, ring at its base. Oesophagus divided into thin muscular and thicker glandular regions. Intestine broad. Cuticle with transverse striations especially pronounced in females, longitudinal, refractile cuticular bosses present on ventral surface of male only, commencing approximately 9 mm anterior to cloaca and terminating approximately 1 mm anterior to cloaca, increasing in density posteriorly. Lateral cords with 3 columns of nuclei, a narrow, central column of widely–spaced, elliptical nuclei with prominent nucleoli and wider, peripheral columns of closely–spaced, elliptical nuclei with prominent nucleoli. Spicules unequal, dissimilar, sclerotised. Gubernaculum present. Lateral alae and caudal alae absent. Phasmids and deirids not observed. Male: (Holotype measurements presented first in italics, followed by 6 paratypes). BL 44, 47 (42–50) mm. MW 265, 255 (239–292). NR 186, 207 (186–239). EP not observed. MO 413, 331 (212–385).

Posterior end generally tightly coiled. Gub 30, 30 (30–33). Cloacal papillae 11–13 in number, variable in disposition, generally three pairs pre–cloacal, one pair ad–cloacal, one pair immediately post–cloacal and one to three single median papillae ranging 52–212 posterior to cloaca. T 493, 428 (395–477), terminating in single pair small latero-ventral papillae and single smaller median papilla. Female: (Allotype measurements presented first, in italics, followed by 2 complete paratypes and 5 large paratype fragments). BL 90, 95 (82–107). MW 451, 455 (449–477). NR 228, 209 (196–228). EP not observed in allotype, 350 (345–355). MO 322; 411 (345–451). GO 1378, 1196 (928–1457). V 3318, 3148 (2095–4487). T 742, 553 (436–610), terminating in two small latero-ventral papillae and a single smaller median papilla. Microfilariae: (5 specimens from uterus). BL 212 (208–214). MW 5 (4–5). Tail long, filamentous, nuclear column terminating in 5–6 single, elongate nuclei. LNT 23(21–24). Microfilaria unsheathed. Site in host unknown. Distribution and hosts. Breinlia (B.) oweni is known from a single Dactylopsila trivirgata in Papua New Guinea. Although the striped possum occurs also in northern Australia, filarioid nematodes have not been reported from it (Spratt et al., 1991) and filarioids have not been seen in fourteen animals examined from north Queensland. Remarks. Breinlia (B.) oweni is most similar to B. (B.) mackerrasae and B. (B.) presidentei and distinguished from them under the differential diagnosis provided.Published as part of Spratt, David M., 2011, New records of filarioid nematodes (Nematoda: Filarioidea) parasitic in Australasian monotremes, marsupials and murids, with descriptions of nine new species 2860, pp. 1-61 in Zootaxa 2860 (1) on pages 21-23, DOI: 10.11646/zootaxa.2860.1.1, http://zenodo.org/record/528650
