Seven new species of the segmented spider genus Liphistius (Mesothelae, Liphistiidae) in Thailand and Myanmar.

Seven new species of the primitive segmented spider genus Liphistius are described and assigned to species groups based on characters of the male palp and vulva plate. The bristowei group includes L.dawei Sivayyapram & Warrit, sp. nov. (♂♀) from southeastern Myanmar, L.choosaki Sivayyapram & Warrit, sp. nov. (♀) from northwestern Thailand, and L.lansak Sivayyapram & Warrit, sp. nov. (♀) from western Thailand; the trang group (Complex A) contains L.kaengkhoi Sivayyapram & Warrit, sp. nov. (♂♀), L.hintung Sivayyapram & Warrit, sp. nov. (♂♀), L.buyphradi Sivayyapram & Warrit, sp. nov. (♂♀), and L.champakpheaw Sivayyapram & Warrit, sp. nov. (♂♀) from central Thailand.

Complete mitochondrial genome of a sea cucumber, Euapta godeffroyi (Echinodermata, Holothuroidea, Apodida, Synaptidae).

We determined the complete mitochondrial genome sequence of a holothurian Euapta godeffroyi belonging to the order Apodida. The complete mitogenome of E. godeffroyi was 16,410 bp in length and consisted of 13 protein-coding genes (PCGs), two ribosomal RNA genes, and 22 transfer RNA genes. The orders of PCGs and rRNAs did not match those of any recorded holothurian mitogenomes. The maximum likelihood (ML) phylogenetic tree placed E. godeffroyi as the sister group to chiridotid species and supported the monophyly of the order Apodida.

First record of Coillina baka Ying amp; Peng, 1998 (Araneae: Gnaphosidae) from Myanmar, with a description of the previously unknown female.

The gnaphosid spider Coillina baka Yin Peng, 1998, originally described from Yunnan, China is newly recorded from Chin State, Myanmar. While its holotype (male) was the only known record of the spider so far, the female is described and illustrated herein for the first time. The detailed structures of the male palp and female genitalia of this species are depicted, and its possible relationship with some species of Synaphosus Platnick Shadab, 1980 is briefly discussed.

First record of Cynipidae from Myanmar with description of a new species of Lithosaphonecrus (Hymenoptera: Cynipidae: Synergini).

A new cynipid species, Lithosaphonecrus mindatus Ide, Aung Tanaka, sp. nov., is described from Chin State, northwestern Myanmar. This is the first record of Cynipidae from this country. The new species emerged from a bud gall of Lithocarpus thomsonii. The new species' morphological features closely resemble L. arcoverticus Liu, Zhu Pang, but differ from the latter due to the presence of a broad foveal septum on the mesoscutellum and short triangular median mesoscutal impression and absence of the anteroadmedian signum on the mesoscutum. Partial sequences of cytochrome c oxidase subunit I region (614 bp) show a 14-15% difference between the new species and other congeners.
