The spider genus Glenognatha Simon, 1887 (Tetragnathidae) currently has 34 nominal species distributed in Afrotropical region, Indo-Malaya, Nearctic, Neotropics, Oceania and Palearctic regions (Cabra-García Brescovit 2016; World Spider Catalog 2020). It has one representative in India: Glenognatha dentata (Zhu Wen, 1978) (World Spider Catalog 2020). The genus Pachygnatha Sundevall, 1823 currently comprises 46 nominal species distributed in Africa, Holarctic, South and South-East Asia (World Spider Catalog 2020). Biswas and Roy (2004) recorded this genus in India, while they described Pachygnatha silentvalliensis Biswas Roy, 2004. The species is known from its original verbal description only since the genitalic illustrations were apparently not published along with the description (Biswas Roy 2004), thus leaving its identity obscured. To redescribe and illustrate this species, we examined its type material and found that Biswas and Roy (2004) had misidentified the species and in fact it belongs to Tylorida Simon, 1894. In this paper, we describe a new Glenognatha species from the southern Western Ghats of India, transfer Dyschiriognatha ganeshi Bodkhe, Manthen Tanikawa, 2014 to Glenognatha and synonymise P. silentvalliensis with Tylorida marmorea (Pocock, 1901).

Four new species of the genus Mallinella Strand, 1906, from the natural forests of Malaysia, are described as Mallinella bicanaliculata sp. n. (♂♀), M. calautica sp. n. (♂♀), M. laxa sp. n. (♂♀), and M. obliqua sp. n. (♂♀). The four new species belong to four species groups and were collected from the forest litter in Sabah state by sieving.
Spiders have emerged as one of the leading model organisms in many research fields due to their compelling biology. Often, scientific investigations involving the use of spiders face inevitable problems associated with the lack of specimens from laboratory stock, resulting in difficulties in yielding reproducible investigations for predictive research. Thus, several species of well-studied spiders, including Parasteatoda tepidariorum, have been successfully bred for such purposes. Crossopriza lyoni is a Haplogyne spider, globally distributed and widespread in human inhabitants, prompting interest in various studies over the last decades. Despite its scientific importance, no laboratory-bred C. lyoni has been documented. Therefore, we describe a successful captive breeding system of the species under controlled conditions to establish a laboratory stock culture. Methods for mating induction, egg collection and segregation, artificial embryo incubation, and colony husbandry are discussed. The technique presented is a simple and low-cost approach that is reliable for C. lyoni propagation in the laboratory over several generations.
Two new genera of euophryine jumping spiders in the Laufeia group are established for species from Southeast Asia: Amoenema Yu & Zhang, gen. nov. and Lokina Yu, Maddison & Zhang, gen. nov., with descriptions of 12 new species: Amoenema erhai Yu & Zhang, sp. nov. (♂♀, type species), A. liuae Yu & Zhang, sp. nov. (♂♀), A. zizhongi Yu & Zhang, sp. nov. (♂♀), Lokina blombergi Yu, Maddison & Zhang, sp. nov. (♂♀), L. chiyou Yu & Zhang, sp. nov. (♂♀, type species), L. fuxi Yu & Zhang, sp. nov. (♂♀), L. kubah Yu, Maddison & Zhang, sp. nov. (♂), L. nyuewa Yu & Zhang, sp. nov. (♂♀), L. pixi Yu, Maddison & Zhang, sp. nov. (♂), L. tamasi Yu & Zhang, sp. nov. (♂♀), L. wuyi Yu & Zhang, sp. nov. (♂), L. zhishengi Yu & Zhang, sp. nov. (♂). In addition, three new combinations are proposed: Amoenema robusta (Lei & Peng, 2012) comb. nov. (transferred from Euophrys C. L. Koch, 1834), Lokina eximia (Zhang & Maddison, 2012) comb. nov. (transferred from Laufeia Simon, 1889) and L. tengchongensis (Lei & Peng, 2012) comb. nov. (transferred from Chalcovietnamicus Marusik, 1991).
The genus Savarna Huber, 2005 comprises only five species, from southern Thailand, Peninsular Malaysia and Sumatra. In this study, five new species are described from Thailand: Savarna bannang sp. nov. (Yala), S. chiangmai sp. nov. (Chiangmai), S. huahin sp. nov. (Prachuap Kiri Khan), S. satun sp. nov. (Satun), S. thungsong sp. nov. (Nakhon Srithammarat). All new species are described from males and females. The distribution of S. chiangmai sp. nov. represent the northernmost record of the genus.
Predator-prey interactions play important roles in ecological communities. Personality, consistent inter-individual differences in behaviour, of predators, prey or both are known to influence inter-specific interactions. An individual may also behave differently under the same situation and the level of such variability may differ between individuals. Such intra-individual variability (IIV) or predictability may be a trait on which selection can also act. A few studies have revealed the joint effect of personality types of both predators and prey on predator foraging performance. However, how personality type and IIV of both predators and prey jointly influence predator foraging performance remains untested empirically. Here, we addressed this using a specialized spider-eating jumping spider, Portia labiata (Salticidae), as the predator, and a jumping spider, Cosmophasis umbratica, as the prey. We examined personality types and IIVs of both P. labiata and C. umbratica and used their inter- and intra-individual behavioural variation as predictors of foraging performance (i.e., number of attempts to capture prey). Personality type and predictability had a joint effect on predator foraging performance. Aggressive predators performed better in capturing unpredictable (high IIV) prey than predictable (low IIV) prey, while docile predators demonstrated better performance when encountering predictable prey. This study highlights the importance of the joint effect of both predator and prey personality types and IIVs on predator-prey interactions.
A new species of Argiope Audouin 1826, A. hoiseni new species is described from Perak and Selangor, Peninsular Malaysia based on morphology and DNA information of the mitochondrial (16S rRNA, COI and COII) and nuclear-encoded (H3A, 18S rRNA) molecular markers. Epigynal structure suggested Argiope hoiseni to be similar to A. jinghongensis Yin, Peng Wang 1994, A. luzona (Walckenaer 1841), A. pulchella Thorell 1881 and A. taprobanica Thorell 1887. Molecular sequence data including the new species inferred that it is monophyletic with an intraspecific variation of 0.87-3.59 % based on the 16S+COI+COII+H3A dataset. Phylogenetic analyses also revealed insights into the evolutionary lineages of Argiope species in Southeast Asia as well as corroborated recent taxonomic changes and species synonymies associated with Argiope. Two new distribution records were also reported for A. chloreis Thorell,1877 and A. doleschalli Thorell, 1873 in Peninsular Malaysia.
The genus Myrmarachne MacLeay, 1839 (Araneae: Salticidae) is one of the most diversified salticid groups in Southeast Asia, with 23 species previously recorded from Borneo. Based on the collections accumulated from 2004 to 2014 in the Lambir Hills National Park, we herein describe six new species: M. amabilis sp. nov., M. hashimotoi sp. nov., M. lagarosoma sp. nov., M. leptosoma sp. nov., M. salaputium sp. nov. and M. tintinnabulum sp. nov. In addition, we describe the female of M. endoi Yamasaki Ahmad, 2013 for the first time. The male-female combination in M. amabilis sp. nov., M. tintinnabulum sp. nov. and M. endoi were confirmed by DNA barcoding.
Recent linyphiid collections from Laos as well as some additional specimens from Thailand and West Malaysia are examined. Six species and two genera are described as new to science: Bathyphantes paracymbialis n. sp., Nematogmus asiaticus n. sp., Theoa hamata n. sp.; Asiagone n. gen. is erected for Asiagone signifera n. sp. (type species) and A. perforata n. sp.; Laogone n. gen. is established for Laogone cephala n. sp. The following new synonyms are proposed: Gorbothorax Tanasevitch, 1998 n. syn. = Nasoona Locket, 1982; Paranasoona Heimer, 1984 n. syn. and Millplophrys Platnick, 1998 n. syn. = Atypena Simon, 1894; Gorbothorax ungibbus Tanasevitch, 1998 n. syn. = Oedothorax asocialis Wunderlich, 1974; Hylyphantes birmanicus (Thorell, 1895) n. syn. = H. graminicola (Sundevall, 1830). The following new combinations are proposed: Atypena cirrifrons (Heimer, 1984) n. comb. ex from Paranasoona; A. pallida (Millidge, 1995) and A. crocatoa (Millidge, 1995) both n. comb. ex Millplophrys; Nasoona asocialis (Wunderlich, 1974) n. comb. ex Oedothorax Bertkau, 1883; N. asocialis (Wunderlich, 1974), N. comata (Tanasevitch, 1998), N. conica (Tanasevitch, 1998), N. setifera (Tanasevitch, 1998) and N. wunderlichi (Brignoli, 1983), all n. comb. ex Gorbothorax. Eight linyphiid species are newly recorded from Laos: A. cirrifrons (Heimer, 1984), Bathyphantes floralis Tu & Li, 2006, Hylyphantes graminicola (Sundevall, 1830), Nasoona asocialis, N. crucifera (Thorell, 1895), Nasoonaria sinensis Wunderlich & Song, 1995, Neriene birmanica (Thorell, 1887), and N. oxycera Tu & Li, 2006. The linyphiid spider fauna of Laos currently contains 15 species and is unusually highly specific. All species, except the Palearctic H. graminicola, are probably represented by Southeastern Asian or Oriental autochthons.

Kemajuan negara dan perkembangan bangsa adalah berdasarkan sistem pendidikan yang diamalkan. Pendidikan yang baik dapat melahirkan generasi yang bertanggungjawab dan menghargai kehidupan. Hal ini telah mencetuskan Wawasan Pendidikan Negara yang merupakan inti pati kepada Wawasan 2020. Usaha menyemai nilai murni dan perubahan pendidikan dalam kalangan pelajar kini turut terletak di bahu guru. Sifat kepimpinan yang terdapat pada guru amat penting dalam pembentukan wawasan pendidikan terutama gaya kepimpinan yang digunakan terhadap pelajar. Berdasarkan hala tuju yang telah digariskan, guru perlu menggunakan gaya kepimpinan yang diamalkan secara menyeluruh bagi memastikan segala aktiviti atau strategi yang dirancang mengikut hala tuju tersebut. Peranan seorang guru dalam membentuk wawasan ini juga membantu memberi kefahaman kepada guru dalam segala tindak tanduk yang perlu dilakukannya bagi mencapai Wawasan Pendidikan Negara
Three new species of the genus Asceua Thorell, 1887, from the natural forests of Malaysia, are described as Asceuabifurcasp. n. (♂♀), A.curvasp. n. (♂), and A.trimaculatasp. n. (♀). The genus Asceua is reported from Malaysia for the first time.
Linyphiid spiders collected from the Indo-Malayan Region and kept at three European Museums are studied. Twenty-three known species are newly recorded from continental or insular parts of Southeastern Asia and from the Oriental area of India. Seven new species are described: Asiagone komannai n. sp. (from Thailand), Erigone apophysalis n. sp. and E. sumatrana n. sp. (Sumatra, Indonesia), Gnathonarium luzon n. sp. (Philippines), Ketambea acuta n. sp. (Thailand, Myanmar), Oedothorax myanmar n. sp. (Myanmar) and Theoa malaya n. sp. (West Malaysia).
A taxonomic revision and phylogenetic analysis of the spider genus Glenognatha Simon, 1887 is presented. This analysis is based on a data set including 24 Glenognatha species plus eight outgroups representing three related tetragnathine genera and one metaine as the root. These taxa were scored for 78 morphological characters. Parsimony was used as the optimality criterion and a sensitivity analysis was performed using different character weighting concavities. Seven unambiguous synapomorphies support the monophyly of Glenognatha. Some internal clades within the genus are well-supported and its relationships are discussed. Glenognatha as recovered includes 27 species, four of them only known from males. A species identification key and distribution maps are provided for all. New morphological data are also presented for thirteen previously described species. Glenognatha has a broad distribution occupying the Neartic, Afrotropic, Indo-Malaya, Oceania and Paleartic regions, but is more diverse in the Neotropics. The following eleven new species are described: G. vivianae n. sp., G. caaguara n. sp., G. boraceia n. sp. and G. timbira n. sp. from southeast Brazil, G. caparu n. sp., G. januari n. sp. and G. camisea n. sp. from the Amazonian region, G. mendezi n. sp., G. florezi n. sp. and G. patriceae n. sp. from northern Andes and G. gouldi n. sp. from Southern United States and central Mexico. Females of G. minuta Banks, 1898, G. gaujoni Simon, 1895 and G. gloriae (Petrunkevitch, 1930) and males of G. globosa (Petrunkevitch, 1925) and G. hirsutissima (Berland, 1935) are described for the first time. Three new combinations are proposed in congruence with the phylogenetic results: G. argyrostilba (O. P.-Cambridge, 1876) n. comb., G. dentata (Zhu & Wen, 1978) n. comb. and G. tangi (Zhu, Song & Zhang, 2003) n. comb., all previously included in Dyschiriognatha Simon, 1893. The following taxa are newly synonymized: Dyschiriognatha montana Simon, 1897, Glenognatha mira Bryant, 1945 and Glenognatha maelfaiti Baert, 1987 with Glenognatha argyrostilba (Pickard-Cambridge, 1876) and Glenognatha centralis Chamberlin, 1925 with Glenognatha minuta Banks, 1898.
