Figs 87–95

Diagnosis

Female

Head yellowish ( Figs 88–89).Antenna ( Fig. 91) with funicle brown and clava whitish. Macropterous; fore wing ( Fig. 95) with intricate pattern of brownish bands and spots covering more than half of wing surface. Clypeal margin shallowly emarginate ( Fig. 90). Upper face and vertex with ten large setae ( Fig. 89). Occiput margin abrupt, but not sharply margined ( Fig. 89). Mesepimeral sulcus inconspicuous, although some transverse costulae present ( Fig. 92). Propodeum ( Fig. 94) 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.

Etymology

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

Material examined

Holotype

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.

Description

Female (habitus: Fig. 87)

COLOUR. Head ( Figs 88–89) mainly orange-yellow. Mandibles yellowish, teeth reddish-brown. Antenna ( Fig. 91) with scape whitish; pedicel dorsally brown, ventrally yellowish; anellus yellowish; flagellum dark brown except clava yellowish. Mesosoma ( Figs 92–94) 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. 95) with intricate pattern of brownish bands and spots; venation brown; setation brown. Hind wing hyaline. Metasoma ( Fig. 87) 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. 90); gena almost smooth ( Fig. 90). Lower face reticulate, without distinct piliferous punctures. Upper face, including shallow scrobes and adjacent areas, and vertex gradually becoming densely punctulate-reticulate ( Fig. 89). Occiput alutaceous; margin abrupt, but not sharply defined ( Fig. 89). Toruli with lower margins below lower margins of eyes ( Fig. 88). Antenna moderately clavate, with clava slightly asymmetric ( Fig. 91). Upper face and vertex with ten large setae ( Fig. 89). 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. 93). Mesonotum moderately setose dorsally ( Fig. 93). Mesoscutum and axillae with dense punctulate reticulation ( Fig. 93). Scutellum as for mesoscutum, except for smoother frenal area ( Fig. 93). Upper mesepisternum smooth; lower mesepisternum reticulate ( Fig. 92). Mesepimeron mainly smooth, becoming shallowly striate posteriorly; mesepimeral sulcus inconspicuous, although with some transverse costulae ( Fig. 92). Propodeum mainly smooth, with large smooth areas among carinae ( Fig. 94). Macropterous; fore wing ( Fig. 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. 87); 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.

Male

Unknown.

Distribution

Dominican Republic.

Remarks

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. 95).
