Treatment

Pseudoacanthocephalus nguyenthileae Amin, Ha & Heckmann, 2008 View in CoL ( Figs. 7 View Fig , 8 View Fig ; Table 1)

Host of present specimens: Bufo melanostictus (Schneider) ( Anura : Bufonidae ).

Locality of present specimens: Shuiman, Wuzhishan Mountain, Hainan Province.

Site in host: Intestine.

Prevalence and intensity of infections: Ten out of 39 individuals of B. melanostictus infected with intensity of 1–8 (mean 2.7) acanthocephalans.

Voucher specimens: Nine male, 10 females ( HBNU – A–A2023015 ZL); deposited in the College of Life Sciences , Hebei Normal University, Hebei Province, China .

Representative DNA sequences: Representative genetic data were deposited in the National Center for Biotechnology Information ( NCBI) database (http://www.ncbi. nlm.nih.gov) under the accession numbers: PP447459, PP447460 (18S); PP466919, PP466920 ( ITS); PP476963, PP476964 (cox1); PP486177, PP486178 (cox2); PP471562, PP471563 (12S); PP476192 (mitogenome).

Remarks

In the present study, the morphology of P. nguyenthileae was observed using light microscopy and, for the first time, scanning electron microscopy based on newly collected specimens from Bufo melanostictus (Schnei- der) in China. Te morphology and morphometric data of the present specimens agreed well with the original description of P. nguyenthileae [ 1], including the size of the trunk, neck, lemnisci, proboscis receptacle and testis; the size and armature of the proboscis; the number and arrangement of cement glands (4 long and 4 clavate); and the size of eggs (See Table 1 for details). Furthermore, the present specimens and some of Amin et al.’s specimens were both collected from the same host B. melanostictus in a neighboring region of Southeast Asia [ 1]. Consequently, we considered that the present specimens belong to P. nguyenthileae . Te position of the genital pore of this species appears variable in both males and females from different hosts. Te present study also sequenced the partial cox1, cox2 and 12S data of P. nguyenthileae for the first time, which displayed low level of intraspecific variation only in the partial cox 1 (1.52%) regions between different individuals of P. nguyenthileae . Tese genetic data are very useful for molecular identification of this species in the future. Tis is the first report of this species in China.
