A new thelastomatid species, Aoruroides cochinchinensis sp. n., is described from the hindgut of Vietnamese Panesthiinae cockroaches collected in Bi Doup-Nui Ba National Park. It is the first report of nematodes of the genus Aoruroides Travassos & Kloss, 1958 from mainland Asia. Aoruroides cochinchinensis sp. n. males are characterized by thorn-like cuticular projections on the head end, maximal value of de Man index a (19.5) within the genus, and the nerve ring situated on the border of corpus and isthmus. Earlier, only knob-like cervical cuticular projections were described for males of A. queenslandensis Jex, Cribb & Schneider, 2004.

First Time

Leptotrombidium subquadratum larvae were collected for the first time in 1994 from dogs in Bloemfontein. The larvae have been collected annually, during the summer months, over a period of 6-7 years. Previously the only known hosts were scrub hare (Lepus saxatilis) (locality unknown) and short-snouted elephant shrew (Elephantulus brachyrhynchus) (Kruger National Park). These mites cause severe itching and dermatitis in humans and dogs.

The anatomy of Radopholus gracilis is described, the description being based chiefly on the study of living specimens and intravital staining with methylene blue and neutral red. Cajal's silver impregnation method and Golgi's bichromate silver method, both with slight modifications, prove useful.Cuticle striated with four longitudinal incisures; 16–18 muscle cells in anterior region; head supported by six-ridged cuticular framework with six lips and 16 sense organs; excretory system with anterior and posterior canals opening into an ampulla, all on left side of the body, and a cuticular terminal duct; ovaries opposed and outstretched; vas deferens differentiated into three regions and no central rachis in the gonads; nerve ring associated with a group of 7, 13, and 27 cells on dorsal, ventral, and lateral sides respectively; phasmid nerve supply from lateral nerves; 'hemizouid' organ present. The nematodes appear to be adapted to an aquatic environment and seem to be unaffected by low temperatures and low oxygen content in their habitat.

First Report

According to the last information of IUCN Red List, Eurasian lynx has been endangered since 2010. The population of this animal is heavily affected by infectious parasites. Two adult Eurasian lynx (one male and one female) were illegally hunted and found dead in Parvar National Park, Semnan Province, Iran. After the autopsy, the tissue and parasite samples were collected from gastrointestinal tract and transferred to 70% alcohol. Samples were recovered and identified as Joyeuxiella spp. Sonsino, 1889. Tissue samples were taken from the place of sticking of parasites on the intestinal wall, for histopathological examination, and were transferred to 10% buffered formalin. Following routine processes and H&E staining, the slides were examined microscopically. Main histopathological observations were epithelial hyperplasia and destruction, inflammatory cell infiltration in mucosa and submucosa of jejunum. To the best of the author’s knowledge, this is the first report and histopathological study of Joyeuxiella spp. in the world in Eurasian lynx.

Established Population

A relatively large and established population of Houttuynia cordata from Itatiaia National Park in Brazil represents the first record of naturalized Saururaceae in South America. Although the species is potentially invasive, unknown mechanisms have prevented its spread to other localities between 1940, when it was recorded in cultivation in Brazil, and the present. The nearest known naturalized population is situated 5,600 km away, in Costa Rica, Central America.

The chemical constituents of essential oils obtained by hydrodistillation from Zingiber vuquangensis Lý N.S., Lê T.H., Trịnh T. H., Nguyễn V.H., Đỗ N.Đ. and Zingiber castaneum Škorničk. & Q.B. Nguyễn collected from Vu Quang National Park, Hà Tĩnh Province, Vietnam were analysed by GC and GC-MS. β-Pinene (24.7% and 26.1%) and β-caryophyllene (12.3% and 13.9%) were the main constituents in the leaf oil and stem oil of Zingiber vuquangensis. On the other hand the root oil contained bornyl acetate (20.9%), zerumbone (14.1%) and α-humulene (9.6%) while β-pinene (19.6%), 1,8-cineole (15.6%), α-pinene (10.3%) and β-caryophyllene (10.4%) were the significant compounds of the fruit oil. The leaf oil Zingiber castaneum was dominated by β-pinene (30.6%), α-pinene (9.5%), β-caryophyllene (9.4%) and bicycloelemene (9.1%). The compounds occurring in higher quantity in the stem oil were β-caryophyllene (14.7%), δ-cadinene (9.8%), bicycloelemene (8.4%) and α-cubebene (7.8%). However, camphene (15.1%), 1,8-cineole (13.6%), linalool (11.3%) and δ-3-carene (8.5%) were the main compounds of the root oil while ( E)-nerolidol (23.2%), ( Z)-9-octadecenamide (17.3%) and β-caryophyllene (10.8%) were the main constituents of the fruit oil. The essential oil did not exhibit noticeable antimicrobial effects. This is the first report on the volatile compositions of Z. vuquangensis and Z. castaneum.
