Oxyepoecus
''Oxyepoecus'' is a Neotropical genus of ant in the subfamily Myrmicinae. The genus is a member of the tribe Solenopsidini and currently includes 20 species. Distribution The genus of is known from the Neotropics, from Colombia to Chile, where it is collected infrequently. Identification ''Oxyepoecus'' is differentiated from other Solenopsidini by the 11-segmented antennae with a three-segmented apical club, the clypeus with four teeth, and the dentate propodeum. In addition, the petiole and postpetiole nodes are high and often anteroposteriorly compressed. Biology The biology of the genus is poorly known, but three species ('' O. inquilinus'', '' O. daguerrei'', and '' O. bruchi'') are suspected to be inquilines of ''Pheidole'' or '' Solenopsis'', although the exact nature of the relationship is unclear. These three species are considered as " Vulnerable D2" by IUCN, meaning they are suspected to be "facing a high risk of extinction in the wild in the medium-term future" be ...

Oxyepoecus Bidentatus
''Oxyepoecus bidentatus'' is a Neotropical species of ant in the genus '' Oxyepoecus''. The species is only known from workers from Paraguay. Distribution ''Oxyepoecus bidentatus'' is known from three localities of the Paraguayan dry Chaco. Because the maximal distance between localities was 340 km, ''O. bidentatus'' is suspected to be widely distributed in xeromorphic Chacoan forests, even if rarely found. Description Its worker morphology places the species within the ''rastratus'' species-group. ''Oxyepoecus bidentatus'' is the only species of the genus to have both the dorsal surface of the head entirely covered by sculpture and a bidentate subpostpetiolar process. The anterior subpostpetiolar process of '' O. bruchi'' of the ''vezenyii'' species-group is also prominent and bidentate, but the dorsal surface of the head is mainly smooth and shining except for two patches of fine, longitudinal rugulae which do not reach posteriorly to the vertex margin nor laterally to ...

Myrmicinae
Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.Goulet, H & Huber, JT (eds.) (1993) Hymenoptera of the world: an identification guide to families. Agriculture Canada. p. 224 Identification Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present. The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head. Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Petiole (insect Anatomy)
In entomology, petiole is the technical term for the narrow waist of some hymenopteran insects, especially ants, bees, and wasps in the suborder Apocrita. The petiole can consist of either one or two segments, a characteristic that separates major subfamilies of ants. Structure The term 'petiole' is most commonly used to refer to the constricted first (and sometimes second) metasomal (posterior) segment of members of the hymenopteran suborder Apocrita (ants, bees, and wasps). It is sometimes also used to refer to other insects with similar body shapes, where the metasomal base is constricted. The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders. The plump portion of the abdomen posterior to the petiole (and postpetiole in the Myrmicinae) is called the gaster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
