Figures 24–30 , 105G ; map 4

TYPES: Female holotype: D.R.C., Kivu, terr. Lubero, Biambwe, 00 ° 169N, 028 ° 579E, July–August, 1967, dans humus, Celis M.J. (PBI_OON 28844, MRAC 136.725). Paratype: same data (PBI_OON 33813, MRAC 230.608), 1 male.

ETYMOLOGY: Named after the Dutch painter and naturalist Johannes Goedaert (1617–1668). His book Metamorphosis naturalis (1662) includes one of the earliest scientific accounts of insect metamorphosis.

DIAGNOSIS: The male can be recognized by the hornlike median projections (fig. 25B, E) and the narrow, elongated P2 projections (figs. 25E, 26A, D). Females can be recognized by the large, triangular epigastric scape (figs. 30F, 105G).

MALE (figs. 24– 29, 30E): TL 1.45. Habitus as in figures 24A, 27C. Carapace stripes as in Z. redii . Six eyes; ALE largest, PLE smallest; ALE approximately one diameter apart; PME round, not touching; PLE round, well separated from PME; posterior eye row slightly procurved in dorsal view. Prongs as in figure 24E. Endites with a median projection (mp), a P1 projection, a P2 projection, and three additional projections (Pa, Pb, Pc); mp robust, hornlike, directed anteriorly (fig. 25B, E); P1 situated very close to mp (figs. 25B, E, F, 26E, F); P2 situated anterior to seta s4, elongated, projecting toward tip of mp, anterior edge partly serrated, median surface strongly ribbed (figs. 25B, E, 26A, B, D); Pa situated anterior to P2, somewhat crestlike (figs. 25B, E, 26A, D); Pb situated posterior to P2, shape as in figures 25E and 26A, D; Pc a very small protrusion (fig. 25E). Booklung covers relatively small, lighter than surrounding scutum. Ventral lip not constricted. DS long, covering almost entire dorsum, fused to ES (fig. 27C, D). PES fused to ES, forming single ventral scutum that covers nearly full length of abdomen (fig. 27E). PLS with two spigots.

FEMALE (figs. 30A–D, F, 105G): TL 1.38. Habitus as in figure 30A, B. Carapace without stripes. Eyes as in male. Booklung covers relatively small, lighter than surrounding scutum. DS long, covering almost entire dorsum (fig. 30B). PES long, most of ventral abdomen covered (fig. 30D). Lateral apodemes very long. Epigastric scape as in figures 30F and 105G, about half as long as PES.

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the type locality in the Kivu region, D.R.C. (map 4).
