We examined the psychometric properties of a Brazilian Portuguese translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015). A sample of 990 Brazilian adults (560 women, 430 men; Mage = 31.10, SD = 8.94) completed the BAS-2 and measures of life satisfaction, self-esteem, actual-ideal weight discrepancy (women only), breast size dissatisfaction (women only), drive for muscularity (men only), and disordered eating behaviours. Exploratory factor analyses indicated that BAS-2 scores reduced to a single dimension with all 10 items in women and men. Confirmatory factor analysis supported the fit of this one-dimensional factor structure following freeing of error covariances between two pairs of items. BAS-2 scores achieved full scalar invariance across sex, and men had significantly higher BAS-2 scores than women. Internal consistency coefficients were adequate and test-retest reliability was supported up to three weeks in a subsample of 221 participants (140 women, 81 men). Evidence of construct validity was demonstrated through positive associations with indices of psychological well-being and negative associations with indices of negative body image and disordered eating behaviours. Availability of a Brazilian Portuguese translation of the BAS-2 should help to promote greater understanding of positive body image in the Brazilian context.

The monotypic genus Chandleriella Hlaváč, 2000 is reported from China for the first time, and a new species, C. yunnanica Yin, sp. nov. (type locality: Lincang, Yunnan), is described. It can be readily separated from C. termitophila (Bryant, 1915) of Sarawak by possessing a conspicuously modified antennomere 11 of the male.
The colubrid snake genus Dendrelaphis comprises of 45 species (Uetz et al. 2018) of which eleven currently occurs in India (Aengals et al. 2018). A member of this genus, Dendrelaphis caudolineatus (Gray, 1834), was once considered a wide-ranging species in Southeast Asia, the Philippines and the Indo-Australian Archipelago, until Van Rooijen Vogel (2012) resolved taxonomy of this species complex. Now its range is restricted from southern Thailand to Sundaland (Peninsular Malaysia, Sumatra, Billiton and Borneo; presence doubtful in Java of Indonesia) (Van Rooijen Vogel 2012).
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.
The Agrilus purpurifrons species-group comprising twelve species from the Oriental region is defined and revised. A key to species is provided and complemented with illustrations of habitus and genitalia. Three new species are described: Agrilus cameronius sp. nov. (Malaysia); A. puncak sp. nov. (Indonesia); and A. vendibilis sp. nov. (Indonesia). The following taxonomic changes are proposed: the specific names lacroixi Obenberger, 1936 syn. nov. and chapaensis Descarpentries Villiers, 1967 syn. nov. are junior synonyms in the synonymy of A. morio Kerremans, 1895; the name rousselatae Baudon, 1968 stat. rev. is removed from the synonymy of A. lacroixi Obenberger, 1936 and revalidated as the specific name of A. rousselatae Baudon, 1968.

Two new species of black flies, Simulium mainitense and S. tukurongense, are described from Palawan, the Philippines. Both species are placed in the Simulium nitidithorax subgroup of the Simulium tuberosum species-group of Simulium (Simulium). They are characterized by the female sensory vesicle of medium length, pupal thorax covered with round tubercles, and anterodorsal trichomes on the pupal thorax longer than frontal trichomes. This combination of characters separates these two new species from S. quasifrenum Delfinado, the only previously known member of the S. nitidithorax subgroup from Palawan, and nine other related species from Sabah, Sarawak, Peninsular Malaysia and India. Simulium mainitense sp. nov. is distinguished from S. tukurongense sp. nov. in the female by the somewhat larger body size, and greater length ratio of the labrum against the clypeus; and in the pupa by the much longer gill filaments.
Megasybacodes brevitarsis Kakizoe, Maruyama Masumoto, a new genus and new species of the tribe Rhyparini, is described based on a single female from Borneo. It is allied to the genus Sybacodes Fairmaire, 1896, but easily distinguished by its short protarsi, broad flattened basal tarsomeres of the meso- and metatarsi, broad flattened tibiae, and wrinkled pronotal and elytral surfaces. Checklist of rhyparine species from Borneo is also provided.
This study investigates the published literature and incorporates our field data from 1997 to September 2018 to generate an inventory report of primary freshwater fishes for Perak State in Malaysia. We critically examined and enumerated 186 species from 2 classes, 16 orders, 43 families and 114 genera in 57 localities. A total of 173 fish species (91.4%) are native to Perak and 17 species (8.6%) are non-native. The provisional checklist presented herein is conservative and excludes doubtful inventory records that lack synthesis and traceability. We encountered seven taxonomic discrepancies and we also could not confidently identify eight species. These are explicitly discussed to inform future workers.

The genus Theopea Baly, 1864 is redefined. Seventeen species from Sundaland and the Philippines are recognized and classified into four species groups (including seven new species): T. impressa (Fabricius, 1801), T. longicollis (Jacoby, 1896), T. louwerensi Jolivet, 1951, T. lunduensis Mohamedsaid, 1998, T. chungi sp. nov. in the T. impressa group; T. flavipalpis Laboissère, 1940, T. guoi sp. nov., T. lui sp. nov., T. sabahensis sp. nov. in the T. flavipalpis group; T. elegantula Baly, 1864, T. pulchella Baly, 1864, T. fairmairei Duvivier, 1885, T. kedenburgi Weise, 1922, T. houjayi sp. nov., T. tsoui sp. nov., T. yuae sp. nov. in the T. pulchella group; and T. costata (Allard, 1889) in the T. costata group. The following new synonyms are established: Theopea pulchella Baly, 1864 = T. nigricollis Jacoby, 1892 syn. nov.; Theopea impressa (Fabricius, 1801) = T. impressa flavicornis Laboissère, 1940 syn. nov. and T. impressa malaccana Laboissère, 1940 syn. nov.; T. lunduensis Mohamedsaid, 1998 = T. sepilokensis Mohamedsaid, 2000 syn. nov. Lectotypes are designated for Crioceris impressa Fabricius, 1801, Ozomena longicollis Jacoby, 1896, Theopea elegantula Baly, 1864, T. fairmairei Duvivier, 1885, T. nigricollis Jacoby, 1892, and T. pulchella Baly, 1864. Theopea obliterata Jacoby, 1884, T. variabilis (Jacoby, 1887), T. incostata (Allard, 1889), T. clypeata Jacoby, 1896, T. modiglianii Jacoby, 1896, T. dohrni (Jacoby, 1899), T. viridipennis (Jacoby, 1899), and T. weberi (Weise, 1913) are removed from Theopea and regarded as species incertae sedis.

Molecular phylogenetic analyses of the sister species Sphenomorphus stellatus and S. praesignis based on the mitochondrial genes 12S and 16S rRNA recover the former as paraphyletic with respect to the latter in that a specimen of S. stellatus from the type locality in Peninsular Malaysia is more closely related to S. praesignis than to Indochinese populations of S. stellatus. Furthermore, the phylogeny indicates that the Indochinese populations represent two species, thus resulting in four major lineages within this clade. These relationships are consistent with multivariate and univariate analyses of morphological and discrete color pattern data which statistically define and diagnose the four lineages and together with the molecular data, provide the foundation for robust, testable, species-level hypotheses. As such, S. stellatus is herein restricted to Peninsular Malaysia; S. annamiticus is resurrected for the circum-continental populations ranging through southeastern Thailand, southern Cambodia, and southern Vietnam; a new species-S. preylangensis sp. nov.-is described from an isolated mountain, Phnom Chi, from the Prey Lang Wildlife Sanctuary in central Cambodia; and the taxonomy of S. praesignis remains unchanged. The description of S. preylangensis sp. nov. underscores the necessity to conserve this remnant of lowland evergreen rainforest in the Prey Lang Wildlife Sanctuary.
The 'Cephennomicrus group' of Cephenniini includes nine genera distributed mostly in SE Asia (but with some species known also from other continents, except for the Americas). Four new Oriental species are described: Cephennococcus penangensis sp. n. (W Malaysia), Cephennomicrus matangensis sp. n. (E Malaysia), Cephennomicrus selangorensis sp. n. (E Malaysia), and Trurlia nova sp. n. (E Malaysia). Cephennomicrus selangorensis is unique in having the pronotum in both sexes with broad lateral impressions demarcated from the disc by a sharp ridge, a modification slightly similar to that of only one (Australian) congener.

Podolestes parvus sp. nov. is described and illustrated from both sexes from Sarawak, Malaysian Borneo (holotype male Maludam National Park, Betong Division, Sarawak, 10 vii 2012, deposited in RMNH). The new species is closest to P. atomarius Lieftinck, 1950 and is the smallest species yet known in its genus. A full set illustrations of P. atomarius is provided for comparison. [Species Zoobank URL: urn:lsid:zoobank.org:act:EE7ABAB0-8683-4D25-8A2C-76977931FD87].
Three new species of the genus Cyana Walker, 1854 are described: C. artemis sp. n. (southeastern China, Thailand, Laos, Vietnam), C. butyracea sp. n. (Vietnam) and C. kucheri sp. n. (Vietnam). The first two species are related to the Himalayan C. moelleri (Elwes, 1890) and the Indochinese C. intercomma Černý, 2009. Despite the external similarity of C. kucheri sp. n. to C. moelleri and its allies, by the genitalia structure this species is related to C. gazella (Moore, 1872). Adults and male and female genitalia of new and related species are illustrated.
Four new species of Grouvellinus Champion, 1923 with very long median pronotal carina are described from China: G. hongkongensis sp. nov. (Guangdong, Guangxi, Hong Kong), G. longiusculus sp. nov. (Jiangxi), G. mediocarinatus sp. nov. (Fujian, Guangdong), and G. robustus sp. nov. (Anhui). These species are obviously closely related to G. bishopi Jäch, 1984 described from Malaysia (Selangor). The latter is here recorded for the first time from Kedah and Perak (Malaysia). Habitus photographs, detailed line drawings of the male genitalia, as well as a key to the males of the species of Grouvellinus with very long median pronotal carina are provided.

Accurate identification of mosquitoes is crucial for the management and control of vector species. Although Singapore is a tropical country with high mosquito diversity, there are no identification keys specific to its mosquito fauna. An illustrated identification key to the genera of the adult female mosquitoes of Singapore is presented. Twenty genera are characterized and two genera found in Malaysia, Culiseta and Topomyia, are also included. The key will aid non-taxonomically trained operational officers in adult mosquito identification. The key to the genera provides the first crucial step in the process to species identification.
A key is provided to 13 species of Haplothrips recorded from Malesia, the tropical biogeographic region that extends from Peninsular Malaysia to New Guinea. Three new synonyms are established, and H. aliceae sp.n. is described from Sarawak, Timor-Leste and Thailand. In contrast to recent treatments of Haplothrips, one of the most common members of the genus in Australia, H. angustus Hood is recognised as a syn.n. of H. ganglebaueri Schmutz that is widespread from Iran to Indonesia. Difficulties in distinguishing between three of the most common flower-living, Southeast Asian, species of this genus are discussed: H. anceps Hood from northern Australia, H. chinensis Priesner from Hong Kong, and H. brevitubus (Karny) from Japan.

Orthoptera from Sandakan, Sabah are relatively understudied compared to some other parts of Borneo, and lack of information of species there can impede our understanding of the origins and biodiversity of orthopterans in Borneo and, in general, Southeast Asia. Based on a recent orthopteran survey in Sandakan, one new species of Lebinthus Stål is described: Lebinthus sandakan sp. nov. The male calling song of this new species is also presented. The calling song of Cardiodactylus borneoe Robillard Gorochov, 2014 is also described for the first time.
Seven new species of the genus Deltoplastis Meyrick are described: D. acutangulata Wang et Yu, sp. nov., D. anatoliana Wang et Park, sp. nov., D. multidentalis Wang et Yu, sp. nov. and D. similihoristis Wang et Yu, sp. nov. from China; D. aculeata Wang et Yu, sp. nov. and D. spatuliunca Wang et Yu, sp. nov. from Malaysian Borneo; and D. ovidiscalis Park et Wang, sp. nov. from Vietnam. Deltoplastis horistis (Meyrick, 1910) is newly recorded in China and its female is described for the first time. Images of adults and genitalia of the new species are provided.
