Colony composition, arthropod egg predation, and antennal structure of the ant Discothyrea sauteri (Hymenoptera: Formicidae)

Keiichi Masuko
In an evergreen, broadleaf forest in central Japan, we collected 21 colonies of the cryptic ant, Discothyrea sauteri, which nests in small cavities in the soil (ca. 100 mm depth), rotting logs, and dead branches lying on the forest floor. The largest colony contained 132 workers, and one third of the collected queenright colonies were functionally polygynous, as revealed by dissection of the queens. Ant nests collected between April and November contained many globular, arthropod...

Behavior of the queen of Leptanilla clypeata Yamane et Ito collected in the Bogor Botanical Gardens, West Java, Indonesia (Hymenoptera; Formicidae), with a note on colony composition and a description of the ergatoid queen

&
One colony of Leptanilla clypeata Yamane et Ito was collected in the type locality, the Bogor Botanical Gardens, West Java, Indonesia. The colony was composed of one ergatoid queen, 100 workers, and 120 almost uniformly sized larvae. Queen behavior was observed in the laboratory. As shown in L. japonica by Masuko (1989), the queen showed larval hemolymph feeding, and started to lay eggs after frequent feeding of larval and prepupal hemolymph. The morphology of the...

A Taxonomic Study on the Genus Strumigenys Smith, 1860 (Hymenoptera: Formicidae) from Korea with a description of new species

Min-Soo Dong &
Korean species of the genus Strumigenys Smith, 1860 are revised. One new species, Strumigenys calvus sp. nov. and two newly recorded species are presented in this study. The records of Strumigenys sp. in Choi (1995) are here identified as S. kumadori based on the examination of the description and taxonomic key provided by Choi (1995). In order to facilitate proper identification of Korean Strumigenys species, we provide a taxonomic key for all known South Korean...
