Sixteen New Species of Nepomorpha (Heteroptera) Mainly from Sulawesi (Indonesia)

Abstract

Measurements are in mm and are based on five specimens of each sex taken from the sample containing the holotype (if available). They are represented as the range of the sample with the sample mean in italics. Length and width refer to the maximum value of the specified body part oriented horizontally; if not specified they refer to body length and maximal body width. Body length is measured from anterior margin of vertex to apex of hemielytra. Extremities are measured with the ventral side upward, this is especially important in fore tibia of male Micronecta. The ocular index is computed as two times the synthlipsis (S) divided by the difference between width of head (D) and synthlipsis, in formula: 2S/(D-S). This measurement buffers against peaks in the ratio synthlipsis/ width of eye, due to imperfect orientation of the head. Where necessary, other measurements will be discussed under the separate families. The areas in Sulawesi used in indication of the localities are the administrative provinces. Some additional data on the localities sampled by Nieser in 1989 (with numbers N89xx) can be found in Nieser & Chen (1991). Pulau Sangir is a spice island belonging to Sulawesi Utara province. As it lies some 200 Km N. of the northern point of ‘mainland’ Sulawesi it is not on the map used in this paper (fig. 126). Remarks between braces {} after the locality data contain additional information not found on the labels. Abbreviations: brach. = brachypterous, macr. = macropterous; lvIV, lvV = 4th and 5th instar larva respectively; L = length, W is width.
