Limnogeton fieberi was described based on a male holotype (from Mayr���s collection) from Kordofan, Sudan according to Mayr (1853), probably deposited in NHMW. This specimen was not examined.

Distribution. Mabwe, Upemba (Democratic Republic of Congo) (Poisson 1954); Kordofan (Sudan) (Poisson 1967), Egypt (Mayr 1871; Linnavuori 1964; Poisson 1967), Cameroon, Central African Republic, Palestine (Poisson 1967); Brazzaville (Congo) (Poisson 1967); Bangweulu Lake [as R��gion du Lac Bangweolo] (Samfya, Zambia), R��gion de la Kafubu (Lubumbashi, Democratic Republic of Congo) (Poisson 1968 a); Luanza (Kaluko River, Zambia) (Poisson 1969). Measurements (m / f): Total length (from apex of head to apex of abdomen at rest): 40.6���55.9 / 45.0���53.0; greatest width of body: 18.2���25.7 / 19.5���23.1. General coloration. Almost uniformly brown. Body ovate, with wings covering completely abdomen. Head, thorax, and abdomen. Pronotum with longitudinal median carina usually developed on posterior portion; prosternal keel elongate and cylindrical, strongly spiniform, with apex acute (Fig. 2 B, PC). Pilosity poorly developed, covering almost half of connexivum, slightly constricted between spiracles, not extending posteriorly along genital operculum (see Fig. 3 C, compare with Fig. 1 C). Male genitalia: Parameres symmetrical with apex curved, directed upward, not edentate, smoothly curved; length of phallotheca about twice ventral diverticulum in dorsal view; ventral diverticulum not robust; dorsal arms of phallotheca poorly developed and poorly connected or fused along basal portion, rounded at apex, never Ushaped (Fig. 2 C, DA); lateral outer margins of ventral diverticulum straight, not sinuous (Fig. 2 C); ventral diverticulum with anterior margins not strongly sclerotized, narrower, obviously convergent posteriorly in ventral view (Fig. 2 D, MVD). Taxonomic notes. Members of this species are now thought to comprise part of a strange morphocline, including L. expansum and L. scutellatum, for we have always found forms with the dorsal arms of phallotheca short and never V-shaped in L. fieberi (Fig. 2 C), whereas they are either somewhat or quite long in L. scutellatum and L. expansum, respectively (Figs. 1 D, 5 C). This morphological continuum seems to be linked to body size, since males of L. expansum have the dorsal arms extremely V-shaped, divergent, and more promimently developed. By contrast, L. fieberi is the smallest species of this genus and bears dorsal arms that are much shorter., Published as part of Ribeiro, Jos�� Ricardo I., Meyin-A-Ebong, Solange E., Le-Gall, Philippe & Guilbert, Eric, 2014, A taxonomic synopsis of Limnogeton Mayr, 1853 (Insecta: Hemiptera: Heteroptera: Belostomatidae), pp. 573-584 in Zootaxa 3779 (5) on pages 576-578, DOI: 10.11646/zootaxa.3779.5.7, http://zenodo.org/record/225225, {"references":["Mayr, G.
