Four new inquiline social parasite species in the dolichoderine ant genus (Hymenoptera, Formicidae).

Four new inquiline social parasites are described in the dolichoderine ant genus from the Nearctic region, and keys are provided for queens and males of the Nearctic species. The new social parasite species represent the first inquiline species in the genus and the first confirmed inquilines known from the ant subfamily Dolichoderinae. The four new species appear to be workerless inquilines that exploit a single host, (Say), and they represent at least two distinct life history syndromes.

Two new species of socially parasitic ants from the southeastern United States.

In ants, social parasitism is an umbrella term describing a variety of life-history strategies, where a parasitic species depends entirely on a free-living species, for part of or its entire life-cycle, for either colony founding, survival, and/or reproduction. The highly specialized inquiline social parasites are fully dependent on their hosts for their entire lifecycles. Most inquiline species are tolerant of the host queen in the parasitized colony, forgo producing a worker caste, and invest solely in the production of sexual offspring.

sp. n., a new GR Waterhouse, 1841 mimic from Mindanao Island, Philippines.

A description of a new species from the genus Heller, 1912 (Coleoptera: Curculionidae: Pachyrhynchini) from Mt Kitanglad Range Natural Park, an ASEAN Heritage Site in northern Mindanao is presented and illustrated. The recent discovery is also the first mimic record of GR Waterhouse, 1841 which are both found in the same locality. A sp.
