Ditylenchus sarvarae sp. n. (Tylenchina: Anguinidae) from Iran

During a survey of soil nematodes in Iran, a new species of Ditylenchus Filipjev, 1936 was discovered. Ditylenchus sarvarae sp. n. is characterised by its body length (1.0–1.4 mm), lateral field with seven incisures and without areolation, long postuterine sac (1.8–2.8 times the corresponding body diameter) and conical female tail with pointed tip (68–89 μm long, c = 13.7–18.2, c' = 4.2–5.1). Male specimens have conical tails (64–70 μm long, c = 14.5–16.7, c' = 4.0–4.5), spicules (22–26 μm long) and gubernaculum (8–10 μm long). Measurements and illustrations are provided for this new species. A molecular study of the 28S rDNA region of D. sarvarae sp. n. demonstrates that the Iranian species belongs to a separate group compared with the other molecularly characterized species of genus Ditylenchus.

A New Species

During a survey of soil nematodes in Iran, three species of predatory nematodes, including a new species of the genus Mylonchulus Cobb, 1916 were recovered. Mylonchulus kermaniensis sp. n. is characterised by its body length (1.2–1.4 mm), six rows of rasp-like denticles, the sixth line consisting of four denticles, female tail slightly sigmoid, sharply bent ventrad with digitate posterior portion slightly but clearly bent dorsad, (37–49 μm long, c=27.9–38.9, c'=1.2–1.7) with a terminal opening of spinneret. Two advulval papillae present, one is pre-vulval and the other one is located posterior to vulva. Furthermore, two other mononchid species namely M. cf. hawaiiensis (Cassidy, 1931) Goodey, 1951 and Mononchus truncatus Bastian, 1865 were also recovered from soil in the province of Kerman, Iran, the former representing a new geographical record for Iran. Measurements and illustration are provided for these three species. Molecular study of 18S rDNA region of M. cf. hawaiiensis demonstrated that the Iranian population compared with the nearest populations identified as M. hawaiiensis from Japan, shows 5 to 8 nucleotide differences. In addition, phylogeny of Mylonchulus is discussed and a checklist of the species of Mononchida from Iran is provided.

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.

A New Species

A new species of the genus Nothotylenchus, N. persicus n. sp. was collected around the roots of grapevine and is described and illustrated herein based on morphological and molecular studies. The new species is characterised by a body length of 776-900 μm, delicate stylet 5-6 μm long, six lines in the lateral field, post-vulval uterine sac short, 10-18 μm long, female tail elongate-conoid with pointed terminus, and bursa covering 40-45% of tail length. Morphologically, N. persicus n. sp. appears closer to four known species of the genus, namely: N. hexaglyphus, N. affinis, N. medians and N. taylori. The results of phylogenetic analyses based on sequences of D2-D3 expansion region of 28S rRNA gene confirmed the close molecular relationship between N. persicus n. sp. and other anguinids, but Nothotylenchus claded separately from Ditylenchus species.

AbstractRuehmaphelenchus thailandae n. sp., isolated from deciduous dunnage from Thailand, is described and figured. The new species is characterised by the relatively stout body (a = 28.6 and 27.6 for males and females, respectively), three lines in the lateral field, spicules relatively small (12.0-13.3 μm) with weakly developed condylus and rostrum, bursa absent, vulva located at 79.5% of body length, vulval lips slightly swollen, length of post-uterine branch more than half of vulva to anus distance, female tail conoid, ca two anal body diam. long and with a broad terminal process up to 12 μm long. The new species is the third known for the genus. It can be distinguished from R. martinii and R. asiaticus mainly by the different shape and size of its spicules and different shape of the female tail terminus. The separate species status is also supported by ITS-RFLP pattern. Additional measurements of paratype R. asiaticus are appended.

AbstractBursaphelenchus anamurius sp. n. isolated from wilted Turkish pine (Pinus brutia Ten.) wood is described. The new species shares several characters with the hofmanni-group sensu Braasch (2001). It is characterised by a body length of 633 (540-749) μm and 744 (638-867) μm for males and females, respectively, stout body (a = 29 in male and 27 in female), stylet 14 μm long in both males and females, lateral field with three lines, length of postuterine branch one-third to one-half of the vulva to anus distance, conoid female tail (c′ = 3.4) with a finely rounded or pointed terminus, very delicate and relatively straight spicules 10 (9-11) μm long with compact capitulum, broad, not distinctly offset condylus and strong rostrum with a more or less rounded tip lacking a cucullus, shovel-shaped bursa and the presence of seven caudal papillae. Bursaphelenchus anamurius sp. n. differs from other species of the hofmanni-group mainly by having smaller, unusually shaped spicules, shorter condylus and no cucullus. The new species can be differentiated from other Bursaphelenchus species morphologically and by means of ITS-RFLP patterns, particularly by digestion of the PCR product with RsaI, HaeIII, MspI, HinfI and AluI.

A New Species

We describe a new species of Auriculostoma Scholz, Aguirre-Macedo & Choudhury, 2004 based on several sources of information including morphology (light and scanning electron microscopy [SEM]), sequences of two nuclear genes, host association, and geographical distribution. Morphologically, the new species most closely resembles Auriculostoma astyanace Scholz, Aguirre-Macedo & Choudhury, 2004, but differs by having deeply lobated testes and cirrus-sac extending posteriorly to seminal receptacle level. Auriculostoma lobata n. sp. can be readily distinguished from all the other congeners by the combination of the following characters: testes located in tandem, testes deeply lobated, and larger body size. A phylogenetic analysis using 28S rDNA sequences along with those available for other allocreadiid trematodes, revealed that the new species is a sister taxon of A. astyanace, a species described from the banded astyanax, Astyanax fasciatus (Cuvier) in Nicaragua. Auriculostoma totonacapanensis Razo-Mendivil, Mendoza-Garfias, Pérez-Ponce de León & Rubio-Godoy, 2014 from the Mexican tetra, Astyanax mexicanus (De Filippi) in Mexico is the sister taxon of A. astyanace plus the new species. Genetic divergence levels for the 28S rDNA and ITS2 were estimated among the Middle-American species of Auriculostoma infecting characiforms. The validity of the new species is then established by reliable morphological differences, its host association to bryconids (Brycon guatemalensis Regan), restricted geographical distribution (Usumacinta and Lacantun River basins), and genetic divergence levels, albeit relatively low. A morphometric comparison between the new species and the other seven congeneric species was undertaken and, in addition, a taxonomic key to identify the species contained in the genus Auriculostoma, widely distributed across the Americas, is provided.
