ZooKeys 589: 97–106. doi: 10.3897/zookeys.589.7739 Abstract Myrmecophilus americanus and M. albicinctus are typical myrmecophilous insects living inside ant nests. These species are ecologically important due to the obligate association with tramp ant species, includ- ing harmful invasive ant species. However, the taxonomy of these “white-banded ant crickets” is quite confused owing to a scarcity of useful external morphological characteristics. Recently, M. albicinctus was synonymized with M. americanus regardless of the apparent host use difference. To clarify taxonomical relationship between M. albicinctus and M. albicinctus, we reexamined morphological characteristics of both species mainly in the viewpoint of anatomy. Observation of genitalia parts, together with a few external body parts, revealed that M. albicinctus showed different tendency from them of M. americanus. Therefore, we recover M. albicinctus as a distinct species on the basis of the morphology. -

A checklist of 82 ant species recorded from Gambia is given. Key words: ants, faunistics, Gambia, new country records. INTRODUCTION Ants fauna of Gambia (West Africa) is poorly known. Literature data, AntWeb and other Internet resources recorded only 59 species from this country. For comparison from Senegal, which surrounds three sides of Gambia, 89 species have been recorded so far. Both of these records seem poor when compared with 654 species known from the whole western Africa (SHUCKARD 1840, ANDRÉ 1889, EMERY 1892, MENOZZI 1926, SANTSCHI 1939, LUSH 2007, ANTWIKI 2017, ANTWEB 2017, DIAMÉ et al. 2017, TAYLOR 2018). Most records from Gambia come from general web checklists of species. Unfortunately, they lack locality data, date of sampling, collector name, coordinates of the locality and notes on habitats. -

Cannon Nutritional Ecology of the Carpenter Ant Camponotus pennsylvanicus (De Geer): Macronutrient Preference and Particle Consumption Colleen A. Cannon (ABSTRACT) The nutritional ecology of the black carpenter ant, Camponotus pennsylvanicus (De Geer) was investigated by examining macronutrient preference and particle consumption in foraging workers. The crops of foragers collected in the field were analyzed for macronutrient content at two-week intervals through the active season. Choice tests were conducted at similar intervals during the active season to determine preference within and between macronutrient groups. Isolated individuals and small social groups were fed fluorescent microspheres in the laboratory to establish the fate of particles ingested by workers of both castes. Under natural conditions, foragers chiefly collected carbohydrate and nitrogenous material. Carbohydrate predominated in the crop and consisted largely of simple sugars. A small amount of glycogen was present. Carbohydrate levels did not vary with time. Lipid levels in the crop were quite low. The level of nitrogen compounds in the crop was approximately half that of carbohydrate, and exhibited seasonal dependence. Peaks in nitrogen foraging occurred in June and September, months associated with the completion of brood rearing in Camponotus. -

DUBOVIKOFF1 & JOHN T. LONGINO2 1 Department of Entomology, Faculty of Biology and Soil Sciences, Saint Petersburg State University, 7/9 Uni- versiteskaya nab., St. Petersburg, 199034, Russia, [email protected] 2 The Evergreen State College, Olympia WA 98505 USA, [email protected] Abstract Bothriomyrmex paradoxus Dubovikov and Longino sp. nov. is described from Costa Rica, based on two collections from widely separated localities. These are the first collections of the genus Bothri- omyrmex in the Americas. The genus Bothriomyrmex can be divided into Palearctic species (Both- riomyrmex s.s.) and Oriental and Australian species, based on differences in palp formula and queen wing venation. Bothriomyrmex paradoxus shares palp and wing characters with the Palearc- tic species. It is probably native to Central America and long separated from its Old World relatives. Key words: Bothriomyrmex, Formicidae, Dolichoderinae, Costa Rica Introduction The subfamily Dolichoderinae is comprised of 22 genera, the majority of which are Old World (Shattuck 1992, Bolton 2003, Brandão et al. 1999). The dolichoderine genera with significant indigenous radiations in the New World are Azteca, Dolichoderus, Dory- myrmex, Forelius, Linepithema, Liometopum, and Tapinoma. Three additional genera have been reported as rare or introduced elements. Technomyrmex, a diverse genus in the Old World, is represented in the New World by one introduced tramp species and, paradoxi- cally, one native species from Panama and Costa Rica (Wheeler 1934, Longino pers. -
Systematics and Community Composition of Foraging
J. Sci. Univ. Kelaniya 7 (2012): 55-72 OCCURRENCE AND SPECIES DIVERSITY OF GROUND-DWELLING WORKER ANTS (FAMILY: FORMICIDAE) IN SELECTED LANDS IN THE DRY ZONE OF SRI LANKA R. K. SRIYANI DIAS AND K. R. K. ANURADHA KOSGAMAGE Department of Zoology, University of Kelaniya, Sri Lanka ABSTRACT Ants are an essential biotic component in terrestrial ecosystems in Sri Lanka. Worker ants were surveyed in six forests, uncultivated lands and, vegetable and fruit fields in two Districts of the dry zone, Anuradhapura and Polonnaruwa, from November, 2007 to October, 2008 by employing several sampling methods simultaneously along five, 100 m transects. Soil sifting, litter sifting, honey-baiting and hand collection were carried out at 5 m intervals along each transect. Twenty pitfall traps were set up throughout each site and collected after five hours. Air and soil temperatures, soil pH and soil moisture at each transect were also recorded. Use of several sampling methods yielded a higher value for species richness than just one or two methods; values for each land ranged from 19 – 43 species. Each land had its own ant community and members of Amblyoponinae, Cerapachyinae, Dorylinae, Leptanillinae and Pseudomyrmecinae were recorded for the first time from the dry zone. Previous records of 40 species belonging to 23 genera in 5 subfamilies for the Anuradhapura District are updated to 78 species belonging to 36 genera in 6 subfamilies. Seventy species belonging to thirty one genera in 9 subfamilies recorded from the first survey of ants in Polonnaruwa lands can be considered a preliminary inventory of the District; current findings updated the ant species recorded from the dry zone to 92 of 42 genera in 10 subfamilies. -

Dias, W.P.S.P. Premadasa Department of Zoology and Environmental Management, Faculty of Science, University of Kelaniya, Kelaniya 11600 Sri Lanka. E-mails: [email protected], [email protected] Abstract. Agricultural practices are blamed for the reduction of ant diversity on earth. Contribution of four coconut plantations (CP) and four non-agricultural lands (NL) for sustaining diversity and relative abundance of ground-dwelling and ground-foraging ants was investigated by surveying them from May to October, 2018, in a CP and a NL in Minuwangoda, Mirigama, Katana and Veyangoda in Gampaha District that lies in the wet zone, Sri Lanka. Worker ants were surveyed by honey baiting and soil sifting along two transects at three, 50 m2 plots in each type of land. Workers were identified using standard methods and frequency of each ant species observed by each method was recorded. Percentage frequency of occurrence observed by each method, mean percentage frequency of occurrence of each ant species and proportional abundance of each species in each ant community were calculated. Species richness recorded by both methods at each CP was 14–19 whereas that recorded at each NL was 17–23. Shannon-Wiener Diversity Index values (Hʹ, CP: 2.06–2.36; NL: 2.11–2.56) and Shannon- Wiener Equitability Index values (Jʹ, CP: 0.73–0.87; NL: 0.7–0.88) showed a considerable diversity and evenness of ant communities at both types of lands. -

THE TRUE ARMY ANTS of the INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae)
Pacific Insects 6 (3) : 427483 November 10, 1964 THE TRUE ARMY ANTS OF THE INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae) By Edward O. Wilson BIOLOGICAL LABORATORIES, HARVARD UNIVERSITY, CAMBRIDGE, MASS., U. S. A. Abstract: All of the known Indo-Australian species of Dorylinae, 4 in Dorylus and 34 in Aenictus, are included in this revision. Eight of the Aenictus species are described as new: artipus, chapmani, doryloides, exilis, huonicus, nganduensis, philiporum and schneirlai. Phylo genetic and numerical analyses resulted in the discarding of two extant subgenera of Aenictus (Typhlatta and Paraenictus) and the loose clustering of the species into 5 informal " groups" within the unified genus Aenictus. A consistency test for phylogenetic characters is discussed. The African and Indo-Australian doryline species are compared, and available information in the biology of the Indo-Australian species is summarized. The " true " army ants are defined here as equivalent to the subfamily Dorylinae. Not included are species of Ponerinae which have developed legionary behavior independently (see Wilson, E. O., 1958, Evolution 12: 24-31) or the subfamily Leptanillinae, which is very distinct and may be independent in origin. The Dorylinae are not as well developed in the Indo-Australian area as in Africa and the New World tropics. Dorylus itself, which includes the famous driver ants, is centered in Africa and sends only four species into tropical Asia. Of these, the most widespread reaches only to Java and the Celebes. Aenictus, on the other hand, is at least as strongly developed in tropical Asia and New Guinea as it is in Africa, with 34 species being known from the former regions and only about 15 from Africa. -

Vos1;∗ 1 Endless Forms, Naturalis Biodiversity Center, Leiden, 2333 BA, Netherlands *[email protected] Abstract 1 The well-documented, species-rich, and diverse group of ants (Formicidae) are important 2 ecological bioindicators for species richness, ecosystem health, and biodiversity, but ant 3 species identification is complex and requires specific knowledge. In the past few years, 4 insect identification from images has seen increasing interest and success, with processing 5 speed improving and costs lowering. Here we propose deep learning (in the form of a 6 convolutional neural network (CNN)) to classify ants at species level using AntWeb 7 images. We used an Inception-ResNet-V2-based CNN to classify ant images, and three 8 shot types with 10,204 images for 97 species, in addition to a multi-view approach, for 9 training and testing the CNN while also testing a worker-only set and an AntWeb 10 protocol-deviant test set. Top 1 accuracy reached 62% - 81%, top 3 accuracy 80% - 92%, 11 and genus accuracy 79% - 95% on species classification for different shot type approaches. 12 The head shot type outperformed other shot type approaches. -

Behavioral Ecology Symposium ’96: Cushing 165 MYRMECOMORPHY AND MYRMECOPHILY IN SPIDERS: A REVIEW PAULA E. CUSHING The College of Wooster Biology Department 931 College Street Wooster, Ohio 44691 ABSTRACT Myrmecomorphs are arthropods that have evolved a morphological resemblance to ants. Myrmecophiles are arthropods that live in or near ant nests and are considered true symbionts. The literature and natural history information about spider myrme- comorphs and myrmecophiles are reviewed. Myrmecomorphy in spiders is generally considered a type of Batesian mimicry in which spiders are gaining protection from predators through their resemblance to aggressive or unpalatable ants. Selection pressure from spider predators and eggsac parasites may trigger greater integration into ant colonies among myrmecophilic spiders. Key Words: Araneae, symbiont, ant-mimicry, ant-associates RESUMEN Los mirmecomorfos son artrópodos que han evolucionado desarrollando una seme- janza morfológica a las hormigas. Los Myrmecófilos son artrópodos que viven dentro o cerca de nidos de hormigas y se consideran verdaderos simbiontes. Ha sido evaluado la literatura e información de historia natural acerca de las arañas mirmecomorfas y mirmecófilas . El myrmecomorfismo en las arañas es generalmente considerado un tipo de mimetismo Batesiano en el cual las arañas están protegiéndose de sus depre- dadores a través de su semejanza con hormigas agresivas o no apetecibles. La presión de selección de los depredadores de arañas y de parásitos de su saco ovopositor pueden inducir una mayor integración de las arañas mirmecófílas hacia las colonias de hor- migas. Myrmecomorphs and myrmecophiles are arthropods that have evolved some level of association with ants. Myrmecomorphs were originally referred to as myrmecoids by Donisthorpe (1927) and are defined as arthropods that mimic ants morphologically and/or behaviorally. -
Floral Volatiles Play a Key Role in Specialized Ant Pollination Clara De Vega
FLORAL VOLATILES PLAY A KEY ROLE IN SPECIALIZED ANT POLLINATION CLARA DE VEGA1*, CARLOS M.

E-mail [email protected] Tel: +34 954466700 Fax: + 34 954621125 1 ABSTRACT Chemical signals emitted by plants are crucial to understanding the ecology and evolution of plant-animal interactions. Scent is an important component of floral phenotype and represents a decisive communication channel between plants and floral visitors. Floral 5 volatiles promote attraction of mutualistic pollinators and, in some cases, serve to prevent flower visitation by antagonists such as ants. Despite ant visits to flowers have been suggested to be detrimental to plant fitness, in recent years there has been a growing recognition of the positive role of ants in pollination. Nevertheless, the question of whether floral volatiles mediate mutualisms between ants and ant-pollinated plants still remains largely unexplored. 10 Here we review the documented cases of ant pollination and investigate the chemical composition of the floral scent in the ant-pollinated plant Cytinus hypocistis. By using chemical-electrophysiological analyses and field behavioural assays, we examine the importance of olfactory cues for ants, identify compounds that stimulate antennal responses, and evaluate whether these compounds elicit behavioural responses. Our findings reveal that 15 floral scent plays a crucial role in this mutualistic ant-flower interaction, and that only ant species that provide pollination services and not others occurring in the habitat are efficiently attracted by floral volatiles.
