  3. Monomia lucida sp. nov., a new swimming crab (Crustacea: Decapoda: Portunidae) from the South China Sea
    Koch M, ĎuriŠ Z
    Zootaxa, 2018 Feb 27;4387(3):567-579.
    PMID: 29690481 DOI: 10.11646/zootaxa.4387.3.9
    A new species of the portunid genus, Monomia Gistel, 1848, is described from the South China Sea in Vietnam. Monomia lucida sp. nov. is morphologically most similar to M. argentata (A. Milne-Edwards, 1861), which was originally described from Sarawak, on the island of Borneo. In addition to the stout, forward-directed anterolateral teeth of the carapace, the subrectangular sixth segment of the male pleon, and the long and slender laterally bent first gonopods, adults of the new species reach a greater size, and can also be distinguished from M. argentata by the colour pattern on the natatory dactylus. The independent specific status of M. lucida sp. nov. is also supported by molecular evidence. Aside from a comparison of this new species with other known congeners, new photographs of the holotype of M. samoensis (Ward, 1939) are also provided.

    Further results are presented of the first field course at Maliau Basin, Malaysian Borneo organized by Taxon Expeditions, an organization which enables citizen scientists to be directly involved in taxonomic discoveries. Three new species of the aquatic beetle genus Grouvellinus Champion, 1923, namely G. leonardodicaprioisp. n., G. andrekuipersisp. n., and G. questsp. n. were collected jointly by the citizen scientists and taxonomists during the fieldwork in Maliau Basin. Material was mainly sampled from sandstone bottom rocks of blackwater streams at altitudes between 900 m and 1,000 m using fine-meshed hand-nets. The genus is widely distributed in the Oriental and Palearctic regions, but these are the first records from the island of Borneo.

  6. Jumping in the Night: An Investigation of the Leaping Activity of the Western Tarsier (Cephalopachus bancanus borneanus) Using Accelerometers
    Costantini D, Sebastiano M, Goossens B, Stark DJ
    Folia Primatol., 2017;88(1):46-56.
    PMID: 28662508 DOI: 10.1159/000477540
    Accelerometers enable scientists to quantify the activity of free-living animals whose direct observation is difficult or demanding due to their elusive nature or nocturnal habits. However, the deployment of accelerometers on small-bodied animals and, in particular, on primates has been little explored. Here we show the first application of accelerometers on the western tarsier (Cephalopachus bancanus borneanus), a nocturnal, small-bodied primate endemic to the forests of Borneo. The fieldwork was carried out in the Lower Kinabatangan Wildlife Sanctuary, Sabah, Malaysian Borneo. We provide guidelines for the deployment of accelerometers on tarsiers that might also be applied to other primate species. Our collected data on 2 females show levels of leaping activity comparable to those previously described using direct observation of wild or captive individuals. The 2 females showed different patterns of leaping activity, which calls for work to explore individual differences further. Our work demonstrates that accelerometers can be deployed on small primates to acquire body motion data that would otherwise be demanding to collect using classic field observations. Future work will be focused on using accelerometer data to discriminate in more detail the different behaviours tarsiers can display and to address the causes and consequences of individual variations in activity.

    Learning anatomy is the basic and essential component of medical study when students start to learn in medical career. Since five hundred years ago, the human cadaver has been used as the silent mentor for students in learning anatomy. Later, pre-dissected specimens were used in addition to hands-on dissection of human cadaver. Current advances promote the use of anatomical models as well as plastinated specimens. This study focused on analyzing the preference of students towards different learning modalities available for anatomy teaching. It was conducted on first year medical students at the Faculty of Medicine and Health Sciences, University Malaysia Sabah (FPSK, UMS). A total of 76 students (27 males and 49 females) participated in this study. Out of 76 students, 57 (75%) students preferred using human cadaver for anatomy learning. Four students (5.3%) opted for plastinated
    specimen while 15 students (19.7%) chose the plastic model. Knowledge gained in learning Anatomy was said to be easier from cadaver (67.1%), followed by plastinated specimen (35.5%) and plastic models (52.6%). In the present study, 97.4% responded that plastic model was easier to apply their knowledge in objective structured practical examinations. The present study found that using cadaver was still favoured by medical students. Further studies are required to determine the preference between hands-on cadaveric dissections versus pre-dissected specimens.

    Pui YM, Karin BR, Bauer AM, Das I
    Zootaxa, 2017 05 03;4258(6):539-550.
    PMID: 28609896 DOI: 10.11646/zootaxa.4258.6.3
    A new species of the genus Tropidophorus is described from Putai, upper Baleh, Kapit districts, Sarawak, East Malaysia (Borneo). Tropidophorus sebi sp. nov. is diagnosable from congeners from Borneo by the combination of the following characters: head shields present, dorsal and lateral scales smooth; parietal scales in two pairs; supraciliaries eight; supraoculars four; supralabials seven; infralabials four; postmental undivided; longitudinal scale rows 58; ventrals 53; transverse scale rows at midbody 34; subcaudals 98; preanals enlarged, single; and subdigital lamellae of Toe IV 19. In addition, we determine the phylogenetic position of this species within the Tropidophorus group based on mitochondrial markers, and present a key to identification of the known Bornean species in the genus.

  10. The first Philippine species of Loeblites Franz (Coleoptera: Staphylinidae: Scydmaeninae)
    JaŁoszyŃski P
    Zootaxa, 2018 Sep 04;4471(1):185-188.
    PMID: 30313426 DOI: 10.11646/zootaxa.4471.1.11
    Loeblites Franz, 1986 is a genus of Glandulariini with adults sharing a very similar body form and most taxonomically important structures with Syndicus Motschulsky, 1851. One of the most conspicuous differences between these genera is the antennal structure. In Syndicus, the antennomere XI is strongly reduced, much shorter than X and lacks the basal stalk, so that the two terminal antennomeres are compactly assembled. They either form one oval structure that appears as a single antennomere because the base of subconical antennomere XI is as broad as apex of X (Syndicus s. str.) or the antennomere XI forms a distinct small 'papilla' on top of X (subgen. Semisyndicus Jałoszyński, 2004) because the base of antennomere XI is much narrower than apex of X. Adults of Loeblites have unmodified antennae, with the antennomere XI strongly elongate and with a narrow basal stalk; additionally the antennae are strikingly slender, nearly filiform. Morphological structures of both genera were described and illustrated by Jałoszyński (2004, 2005). While Syndicus is species-rich, often abundant in leaf litter and under bark in subtropical forests (Jałoszyński 2004, 2006, 2008, 2009, 2011, 2014; Jałoszyński Nomura 2006; Yin Li 2015; Yin et al. 2014; Yin Zhou 2016; Zhou Yin 2017), and broadly distributed from southeastern Australia, through Southeast Asia, Yunnan (China) and Ryukyus (Japan), up to Sri Lanka, India and the Himalayas, Loeblites comprises merely four species known to occur in Malaysia, Thailand and China (Jałoszyński 2005; Zhou Li 2015). Loeblites mastigicornis Franz, 1986 is known to occur in Chiang Mai (northern Thailand), L. sabahensis Franz, 1992 and L. minor Jałoszyński, 2005 in Sabah (northern Borneo), and L. chinensis Zhou Li, 2015 in Yunnan (southwest China). Two females representing an undescribed species were also recorded from Yunnan by Zhou Li (2015). Specimens of this interesting genus are found rarely, in small numbers and they are typically sifted from leaf litter in subtropical forests.

  11. Microclimate and Physiological Effects in the Roosts of Cave Dwelling Bats: Implications in Roost Selection and Conservation in Sarawak, Malaysian Borneo
    Rajasegaran P, Shazali N, Khan FAA
    Zoolog Sci, 2018 12 04;35(6):521-527.
    PMID: 30520355 DOI: 10.2108/zs170144
    Bats play crucial ecological and economic roles. However, this group of mammals is largely threatened due to anthropogenic activities inside or around their caves. In the present study, we investigate the effects of cave microclimate and physiological parameters on bat roost preference in Fairy Cave Nature Reserve (Fairy Cave NR). The microclimate and physiological parameters including temperature (°C), relative humidity (RH), light intensity (lux), air flow, passage dimension (m), roost height (m) and distance of roost from nearest entrance (m) were measured. Results showed that Emballonura monticola, Hipposideros diadema, Hipposideros larvatus and Penthetor lucasi roost in Fairy Cave NR. These bats can be distinguished by their colony size, roost posture, spatial arrangement and position of their roost. Penthetor lucasi makes up the largest colony in the bright zone, whereas E. monticola has the smallest colony, occupying the twilight zone throughout the cave. Members from the family Hipposideridae roost in the dark portion of the cave with zero light intensity. Emballonura monticola utilizes the hottest roost in the cave compared to the other microbats, whereas H. diadema inhabits the coolest roost. Physiological parameters such as light intensity, passage dimension, and distance from nearest entrance are significant parameters in roosting preferences. These parameters should be monitored to ensure the sustainability of not only the aforementioned species, but also other species that roost in nearby caves of Bau limestone (Wind Cave Nature Reserve: with 13 recorded species).

    Chang CY, Pui WC, Kadir KA, Singh B
    Malar J, 2018 Dec 04;17(1):448.
    PMID: 30509259 DOI: 10.1186/s12936-018-2600-2
    BACKGROUND: Plasmodium knowlesi, a malaria parasite typically found in long-tailed and pig-tailed macaques, is the most common cause of human malaria in Malaysian Borneo. Infections in humans result in a spectrum of disease, including fatal outcomes. Spontaneous splenic rupture is a rare, but severe complication of malaria and has not been reported previously for knowlesi malaria.

    CASE PRESENTATION: A 46-year-old man presented with fever and acute surgical abdomen with concomitant P. knowlesi malaria infection at Kapit Hospital. He was in compensated shock upon arrival to the hospital. He had generalized abdominal tenderness, maximal at the epigastric region. Bedside focused abdominal ultrasonography revealed free fluid in the abdomen. He underwent emergency exploratory laparotomy in view of haemodynamic instability and worsening peritonism. Intraoperatively, haemoperitoneum and bleeding from the spleen was noted. Splenectomy was performed. Histopathological examination findings were suggestive of splenic rupture and presence of malarial pigment. Analysis of his blood sample by nested PCR assays confirmed P. knowlesi infection. The patient completed a course of anti-malarial treatment and recovered well post-operation.

    CONCLUSIONS: Spontaneous splenic rupture is a rare complication of malaria. This is the first reported case of splenic rupture in P. knowlesi malaria infection. Detection of such a complication requires high index of clinical suspicion and is extremely challenging in hospitals with limited resources.

  13. Uncovering karst endemism within Borneo: two new Cyrtodactylus species from Sarawak, Malaysia
    Davis HR, Bauer AM, Jackman TR, Nashriq I, DAS I
    Zootaxa, 2019 Jun 10;4614(2):zootaxa.4614.2.4.
    PMID: 31716380 DOI: 10.11646/zootaxa.4614.2.4
    The island of Borneo lies within one of the most biodiverse regions in the world. Despite this, its documented gekkonid diversity is not commensurate with other areas of Southeast Asia. The megadiverse genus Cyrtodactylus is especially underrepresented. Limestone-karst ecosystems, in particular, harbor many endemic Cyrtodactylus species, but only one karst-dwelling species is currently recognized from Borneo. This paper adds two additional karst-dwelling Cyrtodactylus species-C. muluensis sp. nov. and C. limajalur sp. nov.-from Sarawak, Malaysia. Cyrtodactylus muluensis sp. nov. is endemic to Gunung Mulu and is distinguished from its congeners by having a precloacal groove, 31-38 ventral scales, a maximum SVL of at least 88 mm, enlarged subcaudals, 19-20 subdigital lamellae, and a banded dorsal body pattern. Cyrtodactylus limajalur sp. nov. is endemic to the Serian region and is distinguished from its congeners by having 33-42 ventral scales, enlarged subcaudals, a precloacal pit, a maximum SVL of at least 94 mm, 5-6 enlarged femoral scales, 19-22 subdigital lamellae, and five distinct bands on the dorsum. Both species are phylogenetically distinct and deeply divergent from all other congeners. The description of two new karst-dwelling species highlights the need to conserve karst habitats and the endemic species they harbor.

    PMID: 31667222 DOI: 10.1016/j.dib.2019.104449
    This article provides violent crime data in Malaysia from 2006 to 2017. The violent crimes include murder, rape, gang robbery, robbery and voluntarily causing hurt cases. A total of 330,395 violent crime cases were reported in this 12 year period and the data were tabulated state by state for all thirteen states of Malaysia, including two states in Borneo (Sabah and Sarawak) and one federal territory (Kuala Lumpur). In general, violent crimes show a decreasing trend from 2006 to 2017 in Malaysia. However, armed gang robbery and armed robbery show a fluctuating pattern from 2008 to 2011. A similar pattern was also recorded for unarmed gang robbery from 2008 to 2010. The violent crime data deposited here are available for further analysis, e.g., for identifying risk factors such as demography, lifestyle, socio-economic status, government policies etc. which may be associated with violent crime incidence and pattern across the country.

  19. Bioakumulasi Logam Berat Dalam Ikan Air Tawar di Perairan Sekitar Empangan Lohan, Ranau, Sabah (Heavy Metal Bio-accumulation in Fresh Water Fish Around the Lohan Dam, Ranau, Sabah)
    Jumat Salimon, Maimunah Sulaiman
    Sains Malaysiana, 1997;26(1):61-68.
    A study of the heavy metal bio-accumulation by fresh water fish, Tilapia nilotica around Lohan Dam was carried out in aquarium system. The study showed that the fish tissues cultured in contaminated water samples, (location S3 and 54) contain higher heavy metals concentration compared with the fish cultured in uncontaminated water samples (S1 and S2). The concentrations of Fe, Zn, Mn, Cu, Ni and Cr in fish tissues are higher compared with those of Co, Cd and Pb. The bio-accumulation rates of Zn, Mn, Cu, Ni and Co are 25 times higher than those of the base levels and 10 times higher than those of the controls. The heavy metal bio-accumulation order in T. nilotica is as follows: Mn> Cu> Cr> Ni> Co> Zn> Pb> Cd> Fe. The heavy metal intakes by fish during the experimental period did not exceed the level concentration levels.
