Huge Variation

Summary Bursaphelenchus paraleoni n. sp. was isolated from Loblolly pine, Pinus taeda, logs from the USA. The new species is characterised by a lateral field with three lines, 13-16 μm long stylet with small basal swellings, and the excretory pore located slightly posterior to the nerve ring. The male spicules are mitten-shaped, the lamina smoothly tapering towards the distal tip. The condylus is broadly rounded, with a small dorsally bent hook, rostrum triangular or conical with finely rounded tip, and cucullus absent. One midventral precloacal papilla, one adcloacal pair and two postcloacal pairs of genital papillae are present. The bursal flap is long and spade-like with the posterior margin truncate or irregular. Females have a small vulval flap 4-6 μm long, a post-vulval uterine sac extending for 34-49% of the vulva to anus distance, a very long tail with slight ventral curvature, mostly filiform and with a finely rounded terminus, occasionally bluntly rounded. Huge variation in the tails of males and females were observed in a culture. It is similar to species of B. eidmanni, B. leoni, and B. silvestris in the leoni-group but detailed phylogenetic analysis based on 18S, ITS and D2-D3 28S sequences confirmed it as a new species.

Summary Ruehmaphelenchus taedae n. sp., isolated from Loblolly pine logs (Pinus taedae L.) from the USA, is described and figured. It is characterised by a relatively slim body (a = 42 and 43 for males and females, respectively), three lines in the lateral field, male spicules relatively small (12-18 μm) with high and dorsally bent condylus and weakly developed rostrum, bursal flap absent, short tail possessing a long terminal spike ending in a bluntly rounded tip and 8.7-13.3 μm long, vulva positioned at ca 83% of body length, vulval flap absent, vulval lips slightly protruding, post-vulval uterine branch extending for less than half of vulva to anus distance, and female tail conoid, ca 3-4 anal body diam. long, with 13.7-18.5 μm terminal projection. The new species can be separated from all other species of the genus by the male tail possessing a long terminal spike and the more anterior excretory pore. Detailed phylogenetic analysis based on 28S D2-D3 region sequences confirmed the status of this nematode as a new species.

A New Species

Bursaphelenchus singaporensis sp. n. isolated in China from packaging wood of deciduous trees, imported from Singapore is described and illustrated. This new species clearly belongs to the B. xylophilus group, having males with the typically shaped spicules with a cucullus at their distal extremity, the typical position and number of caudal papillae (three pairs and one single) and the anterior vulval lip of the females developed as a distinct flap. The new species is characterized by a body length of 792 (553–950) µm and 850 (690–961) µm of males and females, respectively, robust body (a= 34 and 31, resp.), 15–16 µm-long stylet, lateral field with four lines, long postuterine branch (averaging 102 µm) and a strongly conoid female tail (c= 20) with a finely rounded, only slightly ventrally-bent terminus, male with very strong spicules (41–48 µm long), distinct rostrum and small cucullus, and a dorso-ventral visible terminal bursa. Bursaphelenchus singaporensis sp. n. is closely related to other species of the B. xylophilus group (B. xylophilus, B. mucronatus, B. kolymensis, B. fraudulentus, B. conicaudatus, B. baujardi and B. luxuriosae) and similar to B. abruptus. The morphological differentiation is mainly based on the shape of the female tail. However, B. singaporensis sp. n. differs from all other species of the B. xylophilus group by larger spicules. The new species can be differentiated from B. abruptus, B. xylophilus, B. mucronatus, B. fraudulentus, B. conicaudatus and B. luxuriosae by means of ITS-RFLP patterns.

Summary Bursaphelenchus parayongensis n. sp. was isolated from packaging wood of a consignment from China exported to Germany. The new species is characterised by the lateral field with three lines, 9-13 μm long stylet with small basal swellings, and the excretory pore located near the posterior part of metacorpus. The male spicules are mitten-shaped, the lamina smoothly tapers towards the distal tip. The condylus is broadly rounded, with a small dorsally bent hook, rostrum triangular with sharply pointed tip, and without cucullus. One precloacal papilla, one adcloacal pair and two postcloacal pairs of male papillae present, with the posteriormost pair forming ‘gland papillae’. Bursal flap long, spade-like with posterior margin truncate or irregular. Females have a small vulval flap of 2-3 μm long, and a post-vulval uterine sac extending for 55-77% of the vulva to anus distance. Tail cylindrical, mostly (about 70%) with a robust mucron, very short to less than 3 μm, but occasionally tail terminus bluntly rounded, without mucron. It is similar to species in subgroup 3 of the eggersi group including B. carpini, B. clavicauda, B. cryphali and B. yongensis, but morphologically different. Detailed phylogenetic analysis based on partial 18S, ITS and D2-D3 region of 28S sequences has confirmed the status of this nematode as a new species.

1. A detailed morphological study has been made of certain nematodes occurring in the basidiomycetous fungi, Entoloma rhodipolium, Pleurotus corticalus, P. ostreatus, Hygrophorus virgineus and Tricholoma cunifolium.2. From the first three of these, males and females of two species of eelworms have been obtained which are placed in the genus Iotonchium Cobb, 1920. One of these is Iotonchium fungorum (Butschli, 1878) n. comb., originally described by Butschli under the name of Tylenchus fungorum', the other is a new species which is named I. bifurcatum n. sp.3. The males of both species have peculiar lobed, dorso-ventrally flattened heads and a poorly developed mouth spear. The bursa is very large, the spicules have posterior prolongations which arc extruded through the cloaca and ventral post-anal papillae are present. A gubernaculum is absent.

Abstract This species has had limited distribution from its native habitats in the southern region of the USA since its discovery and description (Lobdell, 1930). O. acuta appears to be restricted to feeding on species of pines and loblolly pine, Pinus taeda, is its preferred food source. In its native habitat, populations seldom reach pest status due to the presence of natural enemies. In 1988, it was transported to a pine seed orchard in China on slash pine, Pinus elliottii, scions purchased in the USA. Sun et al. (1996) noted that O. acuta-infested slash pine scions leaving the USA and entering China in 1988 were not subjected to the quarantine restrictions of either country. The loblolly pine mealybug quickly became established and rapidly spread throughout pine plantations in the Guangdong Province, China where it threatens both native and introduced species of pines in the region.

Summary A new species of free-living marine nematode, Diplolaimella ariakensis n. sp., is described from a muddy tidal flat of the Ariake Sea, southern Japan. Diplolaimella ariakensis n. sp. differs from its congeners by the following: presence of ocelli, absence of denticles in the buccal cavity, a long tail (11-14 cloacal body diam., c = 3.2-4.0 in male, 17-21 anal body diam., c = 2.9-3.4 in female), spicules as long as 1.4-1.8 cloacal body diam., gubernaculum 0.4-0.5 cloacal body diam. long with a dorsocaudal apophysis 0.5-0.7 cloacal body diam. long, presence of a precloacal supplement, absence of postcloacal papillae, presence of seven pairs of body pores in male, and the anterior position of the vulva (V = 43-46). A dichotomous key to Diplolaimella species is provided. Almost full-length 18S rRNA and partial cytochrome c oxidase subunit I gene sequences were determined for D. ariakensis n. sp. A maximum likelihood tree of 18S sequences supported a close relationship between D. ariakensis n. sp. and D. dievengatensis.
