  • Diptera: Syrphidae) with Notes on the Placement of the Subfamily by F
    A NEW GENUS OF MICRODONTINE FLIES (DIPTERA: SYRPHIDAE) WITH NOTES ON THE PLACEMENT OF THE SUBFAMILY BY F. CHRISTIAN THOMPSON I discovered the following new genus of Syrphidae while reviewing the Neotropical Microdontinae. I had planned to put aside its de- scription until my study of the subfamily was finished. However, publication of a second species, assignable to it by van Doesburg (1966) has necessitated publishing a name now for this genus so that it can be included in the Catalog of South American Diptera. Paragodon, new genus Very small (4-5 mm.) microdontine flies. Face simple (slightly produced in paragoides); cheeks absent, eyes bordering on the oral opening; eyes dichoptic in both sexes; occiput evenly developed. An- tennae short, about one-half as long as face; aristae short and thick- ened. Thorax about as long as broad; pleura bare except mesopleura pilose and meta.pleura with microscopic, pile; scutellum without apical spines and fringe; metasterna undeveloped and bare; metathoracic spiracles without hair fringes. Legs simple, with no basal setal patches on the femora and with cicatrices only on the hind femora. Vings without the spurious vein, with all apical crossveins straight. Abdomen oval, lateral margins slightly emarginate and rolled under ventrally, with ISt sternite bare and st spiracles without hair fringes. Genitalia simple; ejaculatory apodeme simple, apical por- tion not triangularly flared; ejaculato.ry sac not sclerotized; ejacula- tory process single, short, not posteriorly fused to ejaculatory hood; ejaculatory hood with anterior ventral portion elongate; sustentacu- lar apodeme present, double, fused anteriorly to base of ejaculatory Contribution no. 1392 from the Systematics and Morphology Research Laboratory, Department of Entomology, University of Massachusetts.

  • Twignesting Ants: the Hidden Predators of the Coffee Berry Borer

Philpott2 1 Department of Ecology and Evolutionary Biology, 830 N. University, University of Michigan, Ann Arbor, MI 48195, U.S.A. 2 Department of Environmental Sciences, 2801 W. Bancroft St., Mail stop 604, University of Toledo, Toledo, OH 43606, U.S.A. ABSTRACT Coffee is a globally important crop that is subject to numerous pest problems, many of which are partially controlled by predatory ants. Yet several studies have proposed that these ecosystem services may be reduced where agricultural systems are more intensively managed. Here we investigate the predatory ability of twig- nesting ants on the main pest of coffee, the coffee berry borer (Hypothenemus hampei) under different management systems in southwest Chiapas, Mexico. We conducted both laboratory and field experiments to examine which twig-nesting ant species, if any, can prey on free-living borers or can remove borers embedded in coffee fruits and whether the effects of the twig-nesting ant community differ with habitat type. Results indicate that several species of twig-nesting ants are effective predators of both free-living borers and those embedded in coffee fruits. In the lab, Pseudomyrmex ejectus, Pseudomyrmex simplex, and Pseudomyrmex PSW-53 effectively removed free-living and embedded borers. In the field, abundance, but not diversity, of twig-nesting ant colonies was influenced by shade management techniques, with the highest colony abundance present in the sites where shade trees were recently pruned.

C. 20013-7012 USA E-mail: [email protected] Abstract A new genus and species of flower flies is described from China (Furcantenna Cheng, type F. yangi Cheng). Another new genus is proposed for the Afrotropical species incorrectly placed in Ceratophya, Afromicrodon Thompson, type Microdon johannae Doesburg. A key is provided to the groups of the Subfamily Microdontinae, along with a checklist of genus-group names proposed within the subfamily and nomenclatural and taxonomic notes on them. Key words: Taxonomy, Syrphidae, Microdontinae, key, China, Afrotropics Introduction Microdontine flies are an unusual group among the flower flies. The adults are rarely encountered as they do not go to flowers and remain close to their breeding sites. The known larvae are predators of ant brood, and, hence, found in ant nests (Andries 1912, Duffield 1981). Adults are found commonly around those nests and do not range far from them. Normally microdontine flies are rare in Malaise and other kind of traps, but if the trap is close to ant nests, then adults can be abundant in the trap samples.

While 21 some dominant individuals (winners) get to monopolize resources, during dyadic interactions, 22 they can increase their relative fitness as compared to subdominant individuals (losers). In some 23 ant species, dominance hierarchies have been used to explain species coexistence and 24 community structure. However, it remains unclear whether or in what contexts dominance 25 hierarchies occur in tropical ant communities. Furthermore, it can be challenging to infer and 26 quantify reliable dominance hierarchies from observed interactions.

  • Diptera: Syrphidae) of Surinam, with a Key to the Neotropical Genera Menno Reemer
    Tijdschrift voor Entomologie 157 (2014) 27–57 brill.com/tve A review of Microdontinae (Diptera: Syrphidae) of Surinam, with a key to the Neotropical genera Menno Reemer The fauna of Microdontinae (Diptera: Syrphidae) of Surinam is reviewed, based on a recent field survey by the author and a re-evaluation of previously collected material, mostly deposited in the RMNH collection (Leiden). A key to all 28 Neotropical genera of the subfamily is given. A total number of 42 species belonging to 13 genera are recorded from Surinam. Habitus photographs of all species are given. Compared with the checklist of Van Doesburg (1966), 24 species are added and five are removed. The following new species are described: Domodon peperpotensis sp. n., Microdon (Microdon) colakriki sp. n., Peradon satyricus sp. n. and Peradon sciarus sp. n. Five possibly new species are left unnamed, pending revisionary work of the species groups they belong to. A neotype is designated for Aphritis angustus Macquart, 1846. The following new synonymies are proposed: Microdon instabilis Wiedemann, 1830 = Microdon aurifex Wiedemann, 1830 jun. syn. n., Microdon batesi Shannon, 1927 = Microdon beebei Curran, 1936 syn. n.

Ennis1, and Stacy M. Philpott Environmental Studies Department, University of California, 1156 High St., Santa Cruz, CA 95064, U.S.A. ABSTRACT Many factors drive the organization of communities including environmental factors, dispersal abilities, and competition. In particular, ant communities have high levels of interspecific competition and dominance that may affect community assembly processes. We used a combination of surveys and nest supplementation experiments to examine effects of a dominant ground-nesting ant (Pheidole synanthrop- ica) on (1) arboreal twig-nesting, (2) ground-foraging, and (3) coffee-foraging ant communities in coffee agroecosystems. We surveyed these communities in high- and low-density areas of P. synanthropica over 2 years. To test for effects on twig ant recruitment, we placed artificial nesting resources on coffee plants in areas with and without P. synanthropica.Thefirst sampling period revealed differences in ant species composition on the ground, in coffee plants, and artificial nests between high- and low-density sites of P. synanthropica. High- density sites also had significantly lower recruitment of twig ants and had species-specific effects on twig ant species.

Mex. (n.s.) 84 (2001) 10. THE SPECIES DESCRIBED BY CARL EDUARD ADOLPH GERSTAECKER Carl Eduard Adolph Gerstaecker died on July 20, 1895 at Greifswald, at the age of 67. He was educated for the medical profession and took his degree, but devoted himself to zoology, especially to entomology. For many years he was keeper of the entomological department of the Berlin Natural History Museum and also a professor of zoology at the University of Berlin. About the year 1876, differences with the then director of the Berlin Museum induced him to resign his appointment in Berlin, and he subsequently accepted the professorship of Zoology at Greifswald, which he held until his death. Gerstaecker was an industrious and thorough worker in all departments of entomology. Among his principal works may be noted the “Arthropoda” in the “Handbuch der Zoologie” (1863) and the same phylum in Bronn´s “Klassen und Ordnungen der Tierreichs”.
