Numbering greater than 9 thousand defined species, ants rank one of the so much plentiful and common of insect groups—the collective weight of ants in tropical forests and grasslands might represent up to 10 to fifteen percentage of the animal biomass. Written through thirty major ant biologists, this complete e-book describes techniques for surveying the variety of ground-dwelling ants. It introduces a standardized protocol for amassing ant samples in any a part of the area and for engaging in repeated sampling through the years, which allows researchers to research worldwide and long term styles. overlaying points of ant ecology and taxonomy, species id, specimen guidance, and resources of sampling apparatus, this booklet presents the mandatory beginning for readers from a variety of backgrounds.

For most type specimens their registration numbers indicate a date before the publication date, as these were specimens Walker described from the BMNH collection. W. Saunders’s collection, these came to the BMNH in 1868 and bear the registration number ‘68 4 ‘. For one specimen there seems some doubt that it is a type (see Sphenorhina duodecimpunctata Walker). With respect to Walker’s (1851) publication an unusual situation arises following the original description of Neosphenorhina ocellata (Walker).
381. ssp. propinqua (Walker, 1851: 671) (Triecphora propinqua); Metcalf, 1961: 150151. Holotype †, Venezuela (BMNH).

[The type genitalia (as ‘holotype’) were figured by China & Myers, 1934: 453, fig. 1b, 1i, 2c. The types are referable to Williams’s (1921) plate 1, figs 3-4. Distant’s varieties ‘a’ and ‘b’ were later named by Lallemand (1912) (see below).
Phalerata). We assume, that in all these cases the type data applies to all taxa that come above the data or up until the next set of data. This interpretation is contrary to Metcalf’s, 1961: 514 catalogue entry for Jacobi’s description of pica, which gives Bolivia (only) for the nominate form. In Jacobi’s 1942 publication (omitted from Metcalf’s (1961) catalogue) he unaccountably gives Sphenorhina in two different formats. It appears first as ‘T. (Sphenorhina)’ for three of the species listed under Tomaspis (trifasciata Melichar, pubescens (Fabricius) and discors Jacobi) and secondly as a general heading for several other species.
