Two new species of Paraneseuthia are described from peninsular Malaysia: P. joeparkeri sp. n. from Bukit Larut (Maxwell Hill) and P. titiwangsana sp. n. from the Genting Highlands. The new species are morphologically allied to species known so far only from Sumatra; they all share emarginate apex of the aedeagus bordered at each side by a subtriangular projection and a pair of setae. This is the first record of this eutheiine genus from the Malay Peninsula and extends the known diversity of Paraneseuthia species within the historical Sundaland area.
Simulium (Nevermannia) ledangense sp. nov. is described from females, males, pupae and mature larvae from Peninsular Malaysia. This new species is assigned to the Simulium feuerborni species-group of the subgenus Nevermannia, and is characterized by the pupa having a very long stalk of the ventral paired gill filaments, which is almost five times longer than the interspiracular trunk and female tergites of segments 2 and 5 to 7 shiny. Taxonomic notes are given to distinguish this new species from three known species of the S. feuerborni species-group from Malaysia.
Taxonomic status of fanged frogs from the Peninsular Malaysia, previously assigned to Limnonectes kuhlii, is assessed using genetic and morphological approaches. Phylogenetic relationships inferred from sequences of the mitochondrial and nuclear genes revealed that the fanged frogs from the Peninsula form a monophyletic group and are clearly divergent from other species previously, or even now, assigned to L. kuhlii from Mainland Southeast Asia. In both mtDNA and nuDNA phylogeny, the Malay Peninsula clade diverges into two lineages, one from north (Larut Hill, Perak, and Hulu Terengganu, Terengganu) and another from south (Genting Highlands, Pahang, and Gombak, Selangor). These lineages are separated by large genetic distances, comparable with those observed between some other species of L. kuhlii-like frogs. Although the two lineages are very similar morphologically, they are distinguishable in several morphological traits and are considered heterospecific. We therefore describe them as L. utara sp. nov. and L. selatan sp. nov. These new species differ from all other species of kuhlii-like frogs from Mainland Southeast Asia by the surface of tibia, which is densely covered by large warts.
A well-supported and well-resolved phylogeny based on a concatenated data set from one mitochondrial and two nuclear genes, six morphological characters, and nine color pattern characters for 44 of the 50 species of the Southeast Asian Rock Geckos (genus Cnemaspis Strauch, 1887) is consistent with the previous taxonomy of Cnemaspis based solely on morphology and color pattern. Cnemaspis is partitioned into four major clades that collectively contain six species groups. The monophyly of all clades and species groups is strongly supported and they are parapatrically distributed across well-established, biogeographical regions ranging from southern Vietnam westward through southern Indochina, southward through the Thai-Malay Peninsula, then eastward to Borneo. Eight new species (Cnemaspis omari sp. nov. from the Thai-Malaysian border; C. temiah sp. nov. from Cameron Highlands, Pahang, Malaysia; C. stongensis sp. nov. from Gunung Stong, Kelantan, Malaysia; C. hangus sp. nov. from Bukit Hangus, Pahang, Malaysia; C. sundagekko sp. nov. from Pulau Siantan, Indonesia; C. peninsularis sp. nov. from southern Peninsular Malaysia and Singapore, and C. mumpuniae sp. nov. and C. sundainsula sp. nov. from Pulau Natuna Besar, Indonesia) are described based on morphology and color pattern and all but C. sundagekko sp. nov. are included in the phylogenetic analyses. Cnemaspis kendallii is polyphyletic and a composite of six species. An updated taxonomy consistent with the phylogeny is proposed for all 50 species and is based on 25 morphological and 53 color pattern characters scored across 594 specimens. Cladogenetic events and biogeographical relationships within Cnemaspis were likely influenced by this group's low vagility and the cyclical patterns of geographical and environmental changes in Sundaland over the last 25 million years and especially within the last 2.5 million years. The phylogeny indicates that nocturnality, diurnality, substrate preferences, and the presence of ocelli in the shoulder regions have evolved independently multiple times.
The small pseudoscorpion family Pseudochiridiidae Chamberlin, 1923 comprises two genera and 12 extant species recorded from Asia (Burma, Christmas Island, Indonesia, India, Nepal, Malaysia, New Guinea, Philippines, Nicobars and Sumba), eastern, central and southern Africa (Chad, D.R. Congo, Kenya, South Africa, Tanzania), Madagascar, Seychelles (Aldabra), North America (Florida) and the Caribbean Islands of Dominican Republic and Cuba (Harvey 2013, Barba & Barroso 2013); one unidentified species is mentioned for the fauna of Mexico (Ceballos 2004). A fossil species has been described from Dominican amber by Judson (2007), who predicted the presence of this family in South America.
The genus Paraheligmonelloides Fukumoto, Kamiya and Suzuki, 1980 (Nippostrongylinae) is revised and split into four genera, mainly based on characters of the synlophe not previously considered at the supraspecific level. These characters mainly include the homology of the left ridge with ridge 1', the relative size of the right ridge to the left ridge and to ridge 1' and the distribution of the largest ridges. Paraheligmonelloides sensu stricto, characterized by the homology of the left ridge with ridge 1', contains only the type species, Paraheligmonelloides kenyensis Fukumoto, Kamiya and Suzuki, 1980, parasitic in a lagomorph from Kenya. Krishnasamyos n. gen., characterized by ridge 1' forming a comarete, two minute left ventral ridges and ridge 1 larger than other dorsal ridges, only includes the species Krishnasamyos triangulus n. comb., parasitic in Malaysian murids. Hughjonestrongylus n. gen., characterized by numerous ridges markedly unequal in size, with the largest ridges grouped in relation to the lateral fields, includes Hughjonestrongylus ennisae n. comb., Hughjonestrongylus amplicaudae n. comb., Hughjonestrongylus mirzai n. comb., and Hughjonestrongylus singauwaensis n. comb., all parasitic in murids from Papua Indonesia and Papua New Guinea. Syafruddinema n. gen., characterized by ridge 1 as long as other dorsal ridges and a gap associated with the left lateral field, between ridges 2' and 3', includes Syafruddinema paruromyos n. comb., Syafruddinema annandalei n. comb., and Syafruddinema eropeplios n. comb., parasitic in murids from Malaysia and Indonesia. A key to the proposed genera is provided.
A new species of Narrow-mouthed frog of the genus Kaloula is described from northern Peninsular Malaysia. Kaloula latidisca sp. nov. is genetically and morphologically most similar to K. baleata and K. indochinensis but differs from those and other congeners by the unique combination of the following characters: (1) adult males SVL 49.2-56.2 mm (x̅=53.5 ± 3.0; N=4); (2) finger tips expanded into large, transversely expanded discs (disc width 2.8-3.1 mm, x̅=3.0 ± 0.1); (3) inner metatarsal tubercle large, oval, distinctly raised, slightly shorter than first toe; (4) three subarticular tubercles on fourth toe; (5) toe webbing formula: I 1-2 II 1-3 III 2-3.5 IV 4-2 V; and (6) yellow to orange irregularly shaped patch on the axillary, inguinal and posterior region of thigh.

We describe two new species and provide one new species record of the family Comesomatidae from a submarine canyon habitat on the Southern Hikurangi margin, New Zealand. Vasostoma hexodontium n. sp. is characterized by having an amphideal fovea with three turns, buccal cavity with six teeth and gubernaculum with long and straight caudal apophyses. Sabatieria dispunctata n. sp. is characterized by the absence of cuticle punctations, large amphideal fovea with 4.5 turns, pharynx with posterior bulb, absence of pre-cloacal supplements, strongly arcuate and cuticularized spicules, simple gubernaculum with short caudal apophyses, and vulva opening directed posteriorly. Laimella subterminata Chen & Vincx, 2000, which was originally described from the Beagle Channel and the Magellan Strait (Chile), is recorded from the Southwest Pacific for the first time.
To date, only the type species Lissonotocoris membranaceus Usinger & Matsuda 1959 is known and recorded from Vietnam and China, Hainan Island. Four new species of the previously monotypic genus Lissonotocoris are described and figured: loebli n.sp. (Thailand), glabronotus n.sp. (N.Vietnam), pachycerus n.sp. (Malaysia) and siamensis n.sp. (Thailand). A key for the identification of all 5 species is provided.

Two new species of Pharta, P. sudmannorum sp. nov. (♂♀, Borneo) and P. koponeni sp. nov. (♂, Thailand) are described. Furthermore, Ibana senagang gen. nov. & sp. nov. from Malaysia is described based on its exceptional palp, which has a reduced, movable conductor and thick-long spines on the distal, ventral surface of the tibia, reminiscent of Epidius Thorell, 1877.
The nematode Pseudoplatycoma malaysianis n. gen. n. sp. is described from the Sulu Sea (Malaysia). The new genus is classified in the subfamily Platycominae Platonova 1976. Revision of the new genus and four other genera in Platycominae, resulted in four species from the genus Platycomopsis being transferred to other genera: P. dimorphica and P. mazjatzavi to the genus Platycoma; P. effilata to the genus Micoletzkyia; and P. gibbonensis to the genus Anticoma. Pilosinema is regarded as a asynonym of Platycomopsis and Platycomopsis paracobbi is regarded as a synonym for P. cobbi. A key for identification of the genera and species of Platycominae is presented.
Phaenandrogomphus safei is described from a male from the Kalabakan Forest Reserve, Sabah, Malaysian Borneo. It is the first species of Phaenandrogomphus to be recorded from Borneo. Onychogomphus treadawayi, known from Busuanga Island in the Palawan region of the Philippines, is transferred to Phaenandrogomphus.
Simulium (Gomphostilbia) hiroyukii is described based on females, males, pupae and larvae collected in Mount Murud, Sarawak, Malaysia. This new species is assigned to the Simulium darjeelingense species-group of the subgenus Gomphostilbia, and is characterized by the darkened fore coxae and the pupal gill with eight long filaments, of which middle and dorsal triplets have elongated primary and secondary stalks, respectively.
Four new species of Cephennomicrus are described from Malaysia: C. curvidens sp. n., C. gentingensis sp. n. (both from the Genting Highlands, West Malaysia), C. santubongensis sp. n. and C. muluensis sp. n. (both from Sarawak, East Malaysia). Male genitalia of all new taxa are illustrated and diagnostic characters are discussed.
A new genus Trachyibana gen. nov. is described and illustrated on the basis of Trachyibana sarawakiensis sp. nov. from Malaysia. The new genus belongs to the family Trachyuropodidae, on the basis of its fringed internal malae, the T-shaped dorsal setae and the position of hypostomal setae h3 (lateral to h1-h2-h4). The new genus differs from the other trachyuropodid genera and species by its lemon-shaped idiosoma, the presence of deep opisthogastric ventral furrows, and the absence of strongly sclerotised dorsal structures.
