Three productidine brachiopods ofHaydenella, Paraplicatifera,andCompressoproductusare recovered from the Tak Fa Formation (Wordian, Middle Permian) of the upper Saraburi Limestone Group exposed at Khao Wong of central Thailand (the western margin of the Indochina Terrane). The latter two genera are new to the Permian of Thailand, and the new speciesParaplicatifera thaicais proposed herewith. Some taxonomic and nomenclatural problems in relation to the three genera are discussed. The assemblage suggests endemism for a Middle Permian marine faunule of the Indochina Terrane.

A new Permian gastropod assemblage from the Roadian (Middle Permian) Khao Khad Formation, Saraburi Group (Lopburi Province, Central Thailand) which is part of the Indochina Terrane, has yielded one of the most diverse Permian gastropod faunas known from Thailand. A total of 44 gastropod species belonging to 30 genera are described herein, including thirteen new species and one new genus. The new genus is Altotomaria. The new species are Bellerophon erawanensis, Biarmeaspira mazaevi, Apachella thailandensis, Gosseletina microstriata, Worthenia humiligrada, Altotomaria reticulata, Yunnania inflata, Trachydomia suwanneeae, Trachyspira eleganta, Heterosubulites longusapertura, Platyzona gradata, Trypanocochlea lopburiensis and Streptacis? khaokhadensis. Most of the species in the studied assemblage represent vetigastropods  (35.6%) and caenogastropods (26.7%) and most of the species belong to Late Palaeozoic cosmopolitan genera. The studied faunas come from shallow water carbonates that are rich in fusulinids, followed by gastropods, ostracods, bivalves and brachiopods. The gastropod assemblage from the Khao Khad Formation shares no species with the gastropod assemblages from other Permian formations in Thailand, the Tak Fa Limestone and the Ratburi Limestone. However, it is similar to the Late Permian gastropod faunas from South China of the Palaeo-Tethys, therefore it suggests that the Indochina Terrane was not located far from South China.

We describe Gekko pradapdao sp. nov. from Tham Khao Chan (Khao Chan Cave), Tha Luang District, Lopburi Province, in central Thailand. The new species, a member of the subgenus Gekko, differs from all currently recognized Gekko species by the following combination of morphological characters and pattern: maximal known snout-vent length of 127.1 mm, lack of contact between nostrils and rostral, 24–28 interorbital scales between supraciliaries, 89–91 scale rows around midbody, 16–18 dorsal tubercle rows at midbody, 30–34 ventral scale rows at midbody, 11–13 precloacal pores in males, a single postcloacal tubercle on each side of the base of the tail, 13–16 subdigital lamellae on 1st toe and 17–19 on 4th toe, no Y-shaped mark on head, non-banded dorsal pattern on a dark chocolate brown to black background, and a dark brown iris. Urgent actions should be taken to evaluate the conservation status of the new species.

Two New Species

We describe two new species of the genus Pristimantis from the western margin of the Eastern Cordillera of Colombia. The species have a sympatric distribution and are found in the humid tropical forests of the lower part of the Tamá National Natural Park (PNN Tamá) and its buffer zone. The new species were described from morphological comparisons and phylogenetic reconstruction from the sequencing of three mitochondrial and two nuclear genes. With these two new species, the number of Pristimantis species known in the department of Norte de Santander has increased to 10. In addition, we included new sequences for the species P. anolirex, P. nicefori, P. mondolfii, and P. yukpa. Our explorations in the last decade indicate that there are probably between five and 10 species that have not been described in the northeastern part of Colombia, especially in areas where the armed conflict has predominated in the last five decades.

Thermosbaenaceans are subterranean crustaceans, widespread and occur in freshwater, oligohaline or anchialine caves or thermal springs. Currently, four families, seven genera,and 45 species are recognised worldwide. During our studies of the isolated karst, Tham Loko (Loko Cave) in Khao Chiason District, Phatthalung Province, we found an undescribed thermosbanacean species in the genus Theosbaena. Theosbaena is the only genus reported from freshwater in the Oriental Region. Previously, there were only two known species, Theosbaena cambodjiana Cals & Boutin, 1985 from Kampot Province, southern Cambodia and Khon Kaen, Thailand and T. kiatwongchai Rogers & Sanoamuang, 2016 discovered in a cave of Takhli District, Nakhon Sawan, central Thailand. Our new species is the third species recorded in the Oriental Region. Theosbaena loko sp. n. differs from its congeners by having a telson 1.8x longer than its breadth, maxilla 1 palp distal segment 4x longer than the proximal palpomere and the maxillopodal exopod twice as long as its basal width. This microshrimp is the third described species of the genus. A key to the species is given and suggestions for the conservation status of the new species are discussed.

Abstract The mirine plant bug genus Prolygus Carvalho, 1987 (Hemiptera: Heteroptera: Miridae: Mirinae: Mirini) and superficially reminiscent taxa in eastern Asia (mainly in Japan, P. R. China and Taiwan) are reviewed. Four species in the region are now assigned to Prolygus. Three new genera, Anthophilolygus gen. nov., Miyamotolygus gen. nov. and Poppiolygus gen. nov., are proposed to accommodate Prolygus bakeri (Poppius, 1915), Neolygus rufilorum (Lu & Zheng, 2004) and Lygus bengalicus Reuter, 1885, respectively. Ten new combinations and three new synonymies are established: Apolygopsis eoa (Poppius, 1915) comb. nov. [transferred from Apolygus China, 1941]; A. fuhoshoensis (Poppius, 1915) comb. nov. [Apolygus]; A. nigra (Poppius, 1915) comb. nov. [Prolygus]; Anthophilolygus bakeri (Poppius, 1915) comb. nov. [Prolygus] = P. tainanensis (Poppius, 1915) syn. nov.; Micromimetus rubrotinctus (Carvalho, 1956) comb. nov. [Lygus sensu lato]; Miyamotolygus bui (Lu & Zheng, 2004) comb. nov. [Neolygus Knight, 1917]; M. pictus (Lu & Zheng, 2004) comb. nov. [Neolygus]; M. rufilorum (Lu & Zheng, 2004) comb. nov. [Neolygus]; Poppiolygus bengalicus (Reuter, 1885) comb. nov. [Lygus sensu lato] = Prolygus kirkaldyi (Poppius, 1915) syn. nov.; Prolygus disciger (Poppius, 1915) comb. nov. [Neolygus]; P. palauensis (Carvalho, 1956) comb. nov. [Lygus sensu lato]; P. nigriclavus (Poppius, 1915) = Neolygus nigroscutellaris (Lu & Zheng, 2004) syn. nov. Two additional new species, Anthophilolygus alaneylesi sp. nov. (central Thailand) and Micromimetus sunweni sp. nov. (Lanyu Island, Taiwan), are also described. The lectotype is designated for Lygus bengalicus Reuter. Lygus sacchari Matsumura, 1910 is regarded as nomen dubium.

A New Species

AbstractFive genera of anthaspidellid and streptosollenid demosponges are described from the Ordovician Lenoir Limestone near Lenoir City, Loudon County, Tennessee, USA including: Rhopalocoelia regularis Raymond and Okulitch, Rugocoelia loudonensis n. sp., Psarodictyum sp. (Anthaspidellidae), Allosacus pedunculatus n. sp., and Zitelella varians Raymond and Okulitch (Streptosolenidae). These findings confirm the major paleobiogeographic picture for Laurentian sponges (i.e., the differential distribution of sponge faunas along both North American margins), because none of these eastern margin species has been reported from western margin faunas. Only one genus typical of the Great Basin fauna, Rugocoelia Johns, 1994, is reported from Tennessee, but as a new species. Possible explanations are discussed for this differential distribution, mainly related to climatic constraints or sedimentary differences, preventing the free distribution of sponge species between Laurentian continental margins.UUID: http://zoobank.org/2b990a4c-7bc8-4eb6-b8a9-fe4ecf7bdbf9

Abstract The Early Permian (Kungurian) Khao Khad Formation of Central Thailand consists mostly of carbonates deposited on the western margin of the Indochina Terrane. This formation has yielded unusual microbial-fusulinid limestones with large gastropods which contribute most to the rock volume. With a height of more than 6 cm, the gastropods are amongst the largest Early Permian gastropods ever reported. Gastropods as major rock formers are rare in the Palaeozoic. This, and other recently reported invertebrate faunas from Thailand show that gastropods may dominate Permian fossil assemblages not only in diversity, but also regarding abundance and in some cases also regarding biomass. Besides gastropods, fusulinids, various calcareous algae, intraclasts and thick microbial-cyanobacterial (Girvanella and Archaeolithoporella) coatings and reticular microbial patches as well as thick inter- and intragranular radial fibrous cement crusts are present. The gastropods represent at least four species and belong probably to undescribed taxa. The fusulinid genus Pseudofusulina and Misellina (M.) termieri are reported from the Khao Khad Formation for the first time and indicate a Bolorian age. Calcareous algae are dominated by dasycladaceans followed by gymnocodiaceans and solenoporaceans. The studied limestone almost completely lacks metazoan reef builders such as corals and sponges. Likewise, brachiopods and bivalves are absent in the studied samples and echinoderms are very scarce. The carbonate is interpreted as product of shallow water, back-reef lagoonal platform community with a high productivity providing the large gastropods with sufficient food. However, conditions were too eutrophic for sessile filter feeders including metazoan reef builders.

Okanagana boweni sp. n. is described from the western margin of the Great Basin of North America. The new species is diagnosed from allopatric O. simulata Davis and sympatric O. utahensis Davis using morphological, bioacoustical, and molecular characters. The distribution of this new species coincides with the Walker Lane region that lies along the border of California and Nevada, USA. Based on geography, bioacoustics, morphology, and molecular phylogenetics, we hypothesize that O. boweni sp. n. is the allopatric sister species of O. simulata.
