Figs 87–95View Figs 87–91View Figs 92–95



Head yellowish ( Figs 88–89View Figs 87–91).Antenna ( Fig. 91View Figs 87–91) with funicle brown and clava whitish. Macropterous; fore wing ( Fig. 95View Figs 92–95) with intricate pattern of brownish bands and spots covering more than half of wing surface. Clypeal margin shallowly emarginate ( Fig. 90View Figs 87–91). Upper face and vertex with ten large setae ( Fig. 89View Figs 87–91). Occiput margin abrupt, but not sharply margined ( Fig. 89View Figs 87–91). Mesepimeral sulcus inconspicuous, although some transverse costulae present ( Fig. 92View Figs 92–95). Propodeum ( Fig. 94View Figs 92–95) without a well-defined V-shaped area basally, with large smooth areas among carinae. Visible part of petiole very short, distinctly transverse, with more or less obliterate sculpture.


The name of the species (adjective) indicates the intricate brownish pattern of the fore wing of the female.

Material examined


DOMINICAN REPUBLIC • ♀; “ DOMINICAN REPUBLIC: Barahona, 7 km NW Paraiso , 200 m, 27.XI.1991, L. Masner & S. Peck, rainforest remnant”; entire, on triangular card, left fore wing glued aside; CNC. 


Female (habitus: Fig. 87View Figs 87–91)

COLOUR. Head ( Figs 88–89View Figs 87–91) mainly orange-yellow. Mandibles yellowish, teeth reddish-brown. Antenna ( Fig. 91View Figs 87–91) with scape whitish; pedicel dorsally brown, ventrally yellowish; anellus yellowish; flagellum dark brown except clava yellowish. Mesosoma ( Figs 92–94View Figs 92–95) dorsally mainly orange, brown on pronotal collar, axillae and propodeum; laterally orange except ventral edges of mesopleuron and metapleuron darker. Legs with fore and hind coxae bright white, mid coxa brown, rest of legs orange-yellow, except brown tarsal pretarsi. Fore wing ( Fig. 95View Figs 92–95) with intricate pattern of brownish bands and spots; venation brown; setation brown. Hind wing hyaline. Metasoma ( Fig. 87View Figs 87–91) with petiole dark brown. Gaster mainly orange-yellow, but brownish both basally and apically. Body setation brownish.

BODY LENGTH. 1.6 mm.

HEAD. Clypeus almost smooth; apical margin very slightly emarginated ( Fig. 90View Figs 87–91); gena almost smooth ( Fig. 90View Figs 87–91). Lower face reticulate, without distinct piliferous punctures. Upper face, including shallow scrobes and adjacent areas, and vertex gradually becoming densely punctulate-reticulate ( Fig. 89View Figs 87–91). Occiput alutaceous; margin abrupt, but not sharply defined ( Fig. 89View Figs 87–91). Toruli with lower margins below lower margins of eyes ( Fig. 88View Figs 87–91). Antenna moderately clavate, with clava slightly asymmetric ( Fig. 91View Figs 87–91). Upper face and vertex with ten large setae ( Fig. 89View Figs 87–91). Head in dorsal view with width about 2.3× length (70:30) and in frontal view about 1.2× height (70:60). POL about 3.2× OOL (19:6). Eye height 1.3× length (37:29), about 2.5× malar space (37:15) and subequal to scape length (37:36). Head width equal to length of pedicel plus flagellum (70:70). Fu1 length equal to width (6:6); fu7 width 1.7× length (10:6); clava length 2.2× width (22:10).

MESOSOMA. Pronotal collar narrower than mesoscutum, with six large setae ( Fig. 93View Figs 92–95). Mesonotum moderately setose dorsally ( Fig. 93View Figs 92–95). Mesoscutum and axillae with dense punctulate reticulation ( Fig. 93View Figs 92–95). Scutellum as for mesoscutum, except for smoother frenal area ( Fig. 93View Figs 92–95). Upper mesepisternum smooth; lower mesepisternum reticulate ( Fig. 92View Figs 92–95). Mesepimeron mainly smooth, becoming shallowly striate posteriorly; mesepimeral sulcus inconspicuous, although with some transverse costulae ( Fig. 92View Figs 92–95). Propodeum mainly smooth, with large smooth areas among carinae ( Fig. 94View Figs 92–95). Macropterous; fore wing ( Fig. 95View Figs 92–95) with basal cell mostly setose, setae denser apically; bare region reaching about middle of marginal vein; setae on infuscate areas darker and longer than those on hyaline areas; setae below parastigma normal, not forming a large patch of conspicuously thicker and longer setation than on other areas. Mesosoma length about 1.3× width (80:60) and 1.6 × height (80:50). Pronotal collar about 0.2× as long as mesoscutum (5:28) and about 0.8 × as wide as mesoscutum (46:60). Mesoscutum width about 2.1× length (60:28). Scutellum length 1.1× width (33:30). Propodeum length about 0.6× scutellum length (20:33). Fore wing length about 2.3× width (125:55); MV about 5.4× SV (43:8), SV equal to PV.

METASOMA. Petiole barely visible, transverse, with several longitudinal costulae. Gaster ovate, length 1.75 × width (105:60) ( Fig. 87View Figs 87–91); gt1 longest, width about 1.9 × length (60:32), with hind margin medially slightly produced; gt2–4 wider than long; gt5 strongly transverse; syntergum acutely pointed. Ovipositor sheaths slightly protruding beyond apex of gaster. Cercal setae not surpassing apex of gaster.




Dominican Republic.


The only known female is somewhat similar to that of N. amethysta  sp. nov., but constitutes one of the most unique-looking species of Netomocera  because of its unique, intricate brownish fore wing colour pattern ( Fig. 95View Figs 92–95).
