Theosbaena loko sp. n. a new stygobiotic microshrimp (Thermosbaenacea: Halosbaenidae) from southern Thailand

Thermosbaenaceans (Thermosbaenacea: Halosbaenidae) are crustaceans, widespread, and occur in various habitats, including oligohaline or anchialine caves, freshwater, thermal springs, or cold waters. Currently, four families, seven genera, and 45 species are recognized worldwide. During the observation in an isolated limestone of Tham Loko (Loko Cave), Khao Chiason District, Phatthalung Province, the Theosbaena loko n. sp. were found. Theosbaena is the only genus reported in the oriental region. There are only two known species, namely Theosbaena cambodjiana Cals & Boutin 1985 from Kampot province, southern Cambodia, and T. kiatwongchai Rogers & Sanoamuang 2016 discovered in a cave of Takhli district, Nakhon Sawan province, central Thailand. Theosbaena loko n. sp. is the third species recorded in the oriental region.A new species Theosbaena loko n. sp. is described from a limestone cave in Phatthalung province, southern Thailand. The new species differs from its congener by having a telson, 1.8 longer than its breadth, maxilla 1 palp distal segment 4 times longer than the proximal palpomere, and the maxillopodal exopod twice as long as its basal width. This micro shrimp is the third described species of the genus known from Thailand and the Oriental region. A key to the species is given and suggestions for the conservation status of the new species are discussed

The complete mitochondrial genome sequence of the karst-dwelling crab, Terrapotamon thungwa (Crustacea: Brachyura: Potamidae)

Terrapotamon thungwa is a new species of terrestrial long-legged crab discovered in a karst landscape of southern Thailand. Here, we report the first complete mitochondrial genome of this crab species. The mitochondrial genome size is 16,156 base-pairs (bp), including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA), and two ribosomal RNA (rRNA) genes. The AT and GC content of the mitochondrial genome sequence is 73.2% and 26.8%, respectively. Phylogenetic analysis with 26 crustacean species, based on 13 mitochondrial conserve genes, showed that T. thungwa was closely related to other freshwater crab species in the family Potamidae

The complete mitogenome of the Thai soldier crab Mictyris thailandensis Davie, Wisespongpand & Shih, 2013 (Crustacea: Decapoda: Mictyridae)

Mictyris thailandensis has been described recently in the family Mictyridae which is found only in the Andaman Sea, west coast of Thailand. In this study, we performed shotgun genome sequencing of a male M. thailandensis using a paired-end (150 bp) sequencing chemistry on MGISEQ-2000RS and report the complete mitochondrial genome of M. thailandensis (15,557 bp). A total of 37 genes have been annotated: 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and a control region. Comparative phylogenetic analysis with 29 crustaceans based on 13 conserved genes demonstrated that M. thailandensis is closely related to other soldier crabs in the family Mictyridae. The mitogenome of M. thailandensis presented here provides useful genetic information to help understand the evolutionary relationships among the Mictyridae family members
