    Soil Macrofauna as Bioindicator on Aek Loba Palm Oil Plantation Land Arlen Hanel Jhon1,2*, Abdul Rauf1, T Sabrina1, Erwin Nyak Akoeb1 1Graduate Program of Agriculture, Faculty of Agriculture, Universitas Sumatera Utara, Medan, Indonesia 2Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Sumatera Utara, Medan, Indonesia *Corresponding author email: [email protected] Article history Received Received in revised form Accepted Available online 13 March 2020 26 July 2020 31 August 2020 31 August 2020 Abstract.The sustainability of oil palm plantation was investigated on the condition of oil palm plantation soil. Soil macrofauna have been reported to be a potential bio indicator of soil health and quality. This research has been conducted at PT. Socfindo Kebun Aek Loba in February 2017- April 2018. The difference in the length of time of utilization and management of plantation land in each generation also determines the presence, both species, density, relative density, and the frequency of the presence of soil macrofauna. This research was conducted to determine the species richness, density and attendance frequency of soil macrofauna on oil palm plantation land of PT. Socfin Indonesia (Socfindo) Aek Loba plantation area. Determination of the sampling point is done by the Purposive Random Sampling method, soil macrofauna sampling using the Quadraticand Hand Sorting methods with a size of 30x30 cm. There are 29 species of soil macrofauna which are grouped into 2 phyla, 3 classes, 11 orders, 21 families, and 27 genera. The highest density value is in the Generation II area of 401.53 ind / m2 and the lowest density value is in the Generation IV area of 101.59 ind / m2.

Box 56–53, ROMANIA *corresponding author, e–mail: [email protected] Received: February 23, 2015; Accepted: June 24, 2015; Available online: April 15, 2016; Printed: April 25, 2016 Abstract. A commented list of 42 centipede species from order Geophilomorpha present in Romania, is given. This comes to complete the annotated catalogue compiled by Negrea (2006) for the other orders of the class Chilopoda: Scutigeromorpha, Lithobiomorpha and Scolopendromorpha. Since 1972, when Matic published the first monograph on epimorphic centipeds from Romania in the series “Fauna României” as the results of his collaboration with his student Cornelia Dărăbanţu, the taxonomical status of many species has been debated and sometimes clarified. Some of the accepted modifications were included by Ilie (2007) in a checklist of centipedes, lacking comments on synonymies. The main goal of this work is, therefore, to update the list of known geophilomorph species from taxonomic and systematic point of view, and to include also records of new species. Key words: Chilopoda, Geophilomorpha, Romania, taxonomy. INTRODUCTION Among centipedes, the Geophilomorpha order is the richest in species number, with 40% of all known species, distributed all over the world (with some exceptions, Antartica and Artic regions) (Bonato et al., 2011a). From the approx. 1250 geophilomorph species, a number of 179 valid species in 37 genera were recently acknowledged to be present in Europe, following a much needed critical review of taxonomic literature (Bonato & Minelli, 2014).

GEOPHILOMORPH CENTIPEDES OF LATVIA (CHILOPODA, GEOPHILOMORPHA). – Latvijas entomologs 42: 5-17. Abstract: The fauna of Geophilomorpha of Latvia was analysed on the basis of a direct study of 64 specimens from 32 localities and a critical revision of all literature data. A total of 10 geophilomorph species occur in Latvia. Geophilus flavus and G. proximus are the most widespread species, whereas four species are known from only one locality each. The Latvian fauna is very similar to that of the entire Baltic basin, with the exception of Strigamia transsilvanica, which is tentatively recorded here for the first time north of the Carpathians. The Latvian populations of G. proximus are most probably parthenogenetic. An illustrated key to the geophilomorph species of Latvia was compiled, including also species hitherto recorded from neighbouring countries only. Key words: Chilopoda, Geophilomorpha, Latvia, fauna, parthenogenesis. Introduction The only available records of geophilomorph centipedes occurring in Latvia are those published by O.Trauberg (1929; 1932). Based on specimens collected in 15 localities, this author identified 6 geophilomorph species, 4 of which were recorded from one locality only.

A new genus Diphyonyx is proposed here for a previously unrecognised lineage of geophilid centipedes. It is distinct from other geophilids in its unique combination of morphological characters, including the peculiar shape of the pretarsus of the legs on the anterior part of the trunk. The type species D. conjungens (Verhoeff, 1898), comb. n., is redescribed in detail and its geographical distribution updated (Balkan Peninsula, Anatolia, Crimea). Included in Diphyonyx are also D. sukacevi (Folkmanová, 1956), comb. n., and D. garutti (Folkmanová & Dobroruka, 1960), comb. n., both from southern Russia. D. garutti is raised here to species rank.

In: Tuf IH, Tajovský K (Eds) Proceedings of the 16th International Congress of Myriapodology, Olomouc, Czech Republic. ZooKeys 510: 95–114. doi: 10.3897/zookeys.510.9614 Abstract A new geophilomorph centipede, Geophilus hadesi sp. n., is described from caves in the Velebit Mountain, central Croatia. Together with Geophilus persephones Foddai & Minelli, 1999, described from Pierre Saint-Martin cave in France, they are the only two remarkably troglomorphic geophilomorphs hitherto known.

  • Hymenoptera: Formicidae: Leptanillinae
    ISSN 1997-3500 Myrmecological News myrmecologicalnews.org Myrmecol. News 31: 85-114 doi: 10.25849/myrmecol.news_031:085 8 April 2021 Original Article The head anatomy of Protanilla lini (Hymeno ptera: Formicidae: Leptanillinae), with a hypothesis of their mandibular movement Adrian Richter, Francisco Hita Garcia, Roberto A. Keller, Johan Billen, Julian Katzke, Brendon E. Boudinot, Evan P. Economo & Rolf G. Beutel Abstract The hypogaeic ant subfamilies Leptanillinae and Martialinae likely form the sister group to the remainder of the extant Formicidae. In order to increase the knowledge of anatomy and functional morphology of these unusual and phyloge- netically crucial ants, we document and describe in detail the cranium of a leptanilline, Protanilla lini Terayama, 2009. The mandibular articulation of the species differs greatly from that of other ants studied so far, and clearly represents a derived condition. We propose a mode of movement for the specialized mandibles that involves variable rotation and sophisticated locking mechanisms. While a wide opening gape and a unique articulation are characteristics of the mandibular movement of P. lini, the observed condition differs from the trap-jaw mechanisms occurring in other groups of ants, and we cannot, at present, confirm such a functional configuration. Protanilla lini displays hardly any plesiomorphies relative to the poneroformicine ants, with the possible exception of the absence of the torular apodeme. Instead, the species is characterized by a suite of apomorphic features related to its hypogaeic and specialized predatory lifestyle. This includes the loss of eyes and optic neuropils, a pronouncedly prognathous head, and the derived mandib- ular articulation. The present study is an additional stepping-stone on our way to reconstructing the cephalic ground plan of ants and will contribute to our understanding of ant evolution.

  • Chilopoda Geophilomorpha
    Records of the Western Austrailan Museum 18: 333-346 (1998). On the species of Tuoba (Chilopoda: Geophilomorpha) in Australia, New Zealand, New Caledonia, Solomon Islands and New Britain R. E. Jones 14 Post Office Road, Dersingham, King's Lynn, Norfolk PE31 6HP, England Abstract The centipede genus TlIoba is reexamined in the Australasian region and four species are found to occur: TZlOba sydneyensis, T latieeps T. xylophaga and a new species T. pa/lida from Western Australia. INTRODUCTION as Algerophilus leptochilus. He also suggested that The taxonomy of the geophilomorph centipedes Geophilus xylophagus and G. hartmeyeri should be found in the littoral zone in Australia has a long included in the same group. A further species and sometimes confusing history. Pocock (1891) mentioned by Brolemann (1931) is G. duponti described Geophilus sydneyensis from Port Jackson (Silvestri, 1897). I have seen this species and it is a and G. (7) laticeps from King Island, (the (?) completely different genus and not a Tuoba. presumably noting that he had strong doubts about Demange (1963) showed that A. leptochilus should the genus) and then he transferred both species to really be called Nesogeophilus leptochilus and later Necrophloeophagus only ten years later (Pocock (1981) stated that it also occurred around the 1901). Specimens from Western Australia referable Seychelles. to both Necrophloeophagus sydneyensis and N. laticeps In searching through the literature in the quest were then described by Attems (1911) as G. for Tuoba and in 'disentangling' Tuoba from hartmeyeri. The latter was placed in Nesogeophilus Tasmanophilus for a revision of the latter genus, I Verhoeff 1924 by Attems (1929), who applied the have examined types and unidentified material genus name to a group of coastal centipedes with a from Australia, Tasmania, New Zealand, New virtually world-wide distribution.
