Behavior and ecology of the enigmatic antLeptanilla japonica Baroni Urbani (Hymenoptera: Formicidae: Leptanillinae)
SummaryThe present study ofLeptanilla japonica has clarified for the first time the biology of the Leptanillinae. Males were obtained, which are the first specimens of the subfamily to be collected

TLDR
The nondestructive form of cannibalism can be regarded as a nutritive adaptation related to the lack of social food transfer in this species, and its specialized predation on large sporadic prey (centipedes).

SummaryThe predatory behavior and prey preferences of 6 species of Oriental dacetine ants of subtribe Strumigeniti are reviewed.Three species of typically long-mandibulateStrumigenys are
The ant genus Leptanilla: discovery of the worker‐associated male of L.japonica, and a description of a new species from Taiwan (Hymenoptera: Formicidae: Leptanillinae)
TLDR
The male and female of Leptanilla japonica Baroni Urbani are described, which is the first worker‐associated male to be discovered in subfamily Leptonillinae and implications of the male morphology and taxonomic positions of the other leptanilline genera based on males are discussed.
Analysis of brood development in the ant Amblyopone silvestrii, with special reference to colony bionomics
TLDR
An examination of the seasonal developmental patterns of immatures collected from more than 100 colonies collected in the field revealed that most or all of the newly hatched individuals overwintered as second to fifth instar larvae and emerged as adults in the next summer.
Larval hemolymph feeding in the ant Leptanilla japonica by use of a specialized duct organ, the “larval hemolymph tap” (Hymenoptera: Formicidae)

  • 1 February 1989
TLDR
The larvae of Leptanilla are properly qualified as a distinct class of caste in ant societies because of the function of this larval organ, which is non-selfish, contributing to overall colony-level functioning.
Predation of centipedes by the primitive ant Amblyopone silvestrii.
TLDR
The ponerine ant Amblyopone silvestrii in nature and in the laboratory observation showed skillful hunting behavior which is highly specialized on large, linear-shaped soil arthropods.
Polygyny and Monoandry in the Ant Formica japonica (Hymenoptera: Formicidae)
TLDR
Comparison of DNA fingerprints of adult and pupal workers with pupal gynes suggested that multiple queens in a nest may contribute unequally to gyne (new queen) production, suggesting the adoption of newly mated queens by established nests.
New exocrine glands in the legionary ants of the genus Leptanilla (Hymenoptera, Formicidae, Leptanillinae)
TLDR
The sternal gland is absent in the queen of L. japonica, and the poison gland is highly degenerated, but the queen is, however, endowed with a series of large, paired, intersegmental tergal and sternal glands, which occur between the IVth through the VIIth segments.
Specialized predation on Oribatid mites by two species of the ant genus Myrmecina (Hymenoptera: Formicidae)
Specialized predation on oribatid mites was confirmed in two Japanese species of the myrmicine genus Myrmecina, the first instance in the Formicidae. Using the mouthparts and legs, a worker
