Abstract

The objective of this study is to observe variations between and within species using morphometry. Collections of Scirpophaga were carried out at rice fields in the Northern Coastal area of Java (Pantura): Kerawang, Cikampek, lndramayu, Cirebon, at sugar-cane plantations in Yogyakarta and Pasuruan and various gramineous crops in areas of South Bandung and Lampung from March 1998 to March 1999. Identification was done using morphology of adult characters. Variation within the population groups are recognized by taking measurement of parts of the head, for example measurement of the length and width of the head. Other characters used ill keying adult Lepidoptera to family are those of willg uenation. Also the morphology of male genitalia were used as main characters to differentiate species Results from this studies shown that: a) Scirpophaga innotata. Measllrement of parts of the head from sample collected showed very little variation, ihier were mentioned as a group. Variation based on wing size, length and width of forewing can be divided into two groups sizes; the large group size (950 - 1025 lI11n/100) and the smolt group size (850 - 860min/100). Variation based on the size of male gellitalia were more varied in ranging; between 20 - 26min/100 in length and 23 - 35 min/100 but they can be put into one group. b) Scirpophaga incertulas. Measurelllent of parts of the head show little variation in the scattered diagram distribution, and is considered as the same population group. Variation based on wing size, length and width of forewing collected from various places in Java indicated that populations of this insect does not indicate any differences in term of types of wing uenations and considered as similar populatious. Variation based on the size of male genitalia seemed to the same group in the scattered diagmm. c) Scirpophaga excerptalis Measurement of parts of the head (the length and width of the head) considerd as one population. Variation based on the size of nutle genitalia seemed to the smile group in the scattered diagrmn.

Abstract

Rats can serve as a reservoir of diseases because the parasites within rats can be transmitted to humans and other animals. One of the parasites comes from the phylum Nematoda. This study aimed to identify the nematode species found in rats, determine their prevalence and intensity in Kalimantan Island. This study used 20 carcasses of rats from Kalimantan Island stored in the wet collection of MZB (Museum Zoologicum Bogoriense) BRIN Cibinong-Bogor. Identification was carried out by observing and measuring the nematodes found using a light microscope and Scanning Electron Microscope (SEM). The nematode species were then calculated for prevalence and intensity in each host. In this study, four species of nematodes, including Subulura (Murisubulura) andersoni (10% and 11-35), Subuluridae gen. sp. (80% and 1-53), Mastophorus sp. (25% and 1), and Physocephalus sp. (25% and 5), were found. Kalimantan Island is a new record area for S (M.) andersoni, Mastophorus sp. and Physocephalus sp. This needs further research to identify Subuluridae gen.sp. and its distribution area in Indonesia.

Abstract

Sulawesi is an important endemicity hotspot in Southeast Asia, with over 100 endemic species distributed on the island. Despite a long history of avian research on Sulawesi that has played a significant role in the development of evolutionary theory, many ornithological aspects remain unknown. The last few decades have seen novel discoveries, for example, in the form of new species range extensions and species discoveries in the face of ongoing habitat loss and conversion. We here report on a range extension and notes of morphological descriptions of the endemic Diabolical Nightjar and Indonesian Serin in Southeast Sulawesi, adding to our knowledge of the distribution of Sulawesi’s avifauna, especially in the southeastern part in which visits from ornithologists are less frequent. A review of recent museum collections adds another new locality for Diabolical Nightjar in South Sulawesi. Future taxonomic studies are needed to elucidate the status of both species, especially in the Indonesian Serin, as the subtle differences in the coloration of the forehead, rump, and upper tail covert may indicate more than one taxon exists in Sulawesi. In addition, we provide an annotated checklist of birds observed during the fieldwork encompassing areas around Kolaka and Makassar.

Abstract

During a plankton trip around Sebatik Island, North Kalimantan, a copepod Labidocera rotunda Mori, 1929 (Calanoida, Pontellidae) was collected for the first time in Indonesian waters. Both sexes are redescribed and compared to previous descriptions. The geographical distribution of the species confirms that it is of Indo-Pacific origin. There has been a mix-up between L. rotunda described by Mori (1929) from Pusan, Korea and L. bipinnata from Sagami Bay, described by Tanaka (1936). Fleminger et al. (1982) have argued that the minor difference is based on the presence or absence of cephalic hooks and had synonymized L. bipinnata with L. rotunda.

Abstract

Papilio peranthus is endemic to Indonesia, where it occurs on several islands and island groups. This beautiful butterfly is extensively traded, thus efforts to breed this species are very desirable. Captive breeding research was conducted on P. peranthus during September 2016 to December 2018. In total, 221 individuals were available for observation. Data on the life cycle of the species, together with observations on females being approached for mating, and female oviposition after mating, are presented. The result demonstrate that P. peranthus is not monogamous. Observations on other biological aspects are also reported.

Abstract

The taxonomy of social wasps of the poiistine tribe Ropalidiini in the eastern part of ti,e Lesser Sunda Islands (viz., Sumba, Flores and Timor as included major islands) was studied based mainly on specimens recently collected by ourselves and those deposited in the Museum Zoologicum Bogoriense, Bogor. Parapolybia varia (Fabricius) and 11 species of Ropalictia are recognized ill tile region and their faunal characteristics are discussed. Nomenclatural changes included are: synonymy of Ropalidia laticincta floresinana van der vecht, 1962 under R. laticincta van der vecht, 1962; synonymies of Icaria nigroplagiata Cameron, 1900, R. mathematica binotata uau der vecin, 1941 and R. mathematica sumbaensis van der vecht, 1962, all under R. mathematica (Smith: 1860); revised status of R. socialis trimarulata van der vecht, 1962, and R. variegata dichrorna van der vecht, 1941, both being raised to species milk. New locality records are R. cyathiformis from Lombok and Flores Islallds, R. laticincta from Sobu (or Sawu) Island, R. rufoplagiata (Cameron) from Timor Island, and R. javanica van der vecht from Sumbawa island.

Abstract

Vespa affinis is a hornet with wide geographical distribution, occurring across the Indonesian Archipelago (Sumatra, Java, Kalimantan, Sulawesi, the Moluccas, and Papua) but excluding the Lesser Sunda Islands. Species with wide distribution typically show morphological variations that may differ across their range. This study aims to provide a detailed description of island-to-island diversity in morphometric characters and marking patterns among Indonesian populations of V. affinis. A total of 18 morphometric characters and 18 color patterns were analyzed. Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) were employed to distinguish variations in morphometric data. Marking pattern data were analyzed using the hierarchical clustering, to understand the clustering and relationship of marking patterns. The morphometric similarity recorded across the Indonesian archipelago suggests limited morphometric divergence among the populations. The marking patterns of V. affinis showed considerable variation across its geographical range, with brighter coloration in populations from eastern Indonesia compared to those from Sundaland.

Abstract

Flying foxes are important ecological keystone species on many archipelagoes, and Indonesia is home to over a third of all flying fox species globally. However, the amount of research on this clade belies their importance to natural systems, particularly as they are increasingly threatened by anthropogenic development and hunting. Here, we provide a review of the literature since the publication of the Old World Fruit Bat Action Plan and categorize research priorities as high, medium, or low based on the number of studies conducted. A majority of the research priorities for Indonesian endemics are categorized as medium or high priority. Low priority ratings were in multiple categories for widespread flying fox species found throughout Southeast Asia, though much of the data were from outside of the Indonesian extent of the species range. These research gaps tend to highlight broader patterns of research biases towards western Indonesia, whereas significant research effort is still needed in eastern Indonesia, particularly for vulnerable island taxa.
