(Figs 578, 579, 992, 1093)
Diagnosis (female). Antennal clava solid (Fig. 1093); genal carina strong and long, reaching up to level of middle of eye; mesoscutellum (Fig. 578) with strong reticulation on median part and isodiametric meshes, lateral parts with strong reticulation, meshes elongate, submedian grooves indistinct, straight and diverging towards posterior part; dorsellum without median carina; propodeum (Fig. 578) with strong reticulation, callus with ten setae; gaster (Fig. 578) elongate, 3.1× as long as wide, medio-basal Gt1 with a strong transverse carina dorsally, Gt1-4 with a smooth median line, tergites with strong reticulation.
Female holotype: length of body 2.5mm (paratype 2.2mm).
Scape yellowish-white, pedicel and flagellum pale brown (antenna appears bleached by light). Face below level of toruli metallic bluish-purple, clypeus yellowish-brown, frons metallic-bluish-green, antennal scrobes black; vertex black with blue-green tinges. Thoracic dorsum metallic bluish-green. Legs with fore and mid coxae dark brown, hind coxa metallic bluish-green; trochanters yellowish-white; femora with basal half dark brown and apical half yellowish-white; tibiae and tarsi yellowish-white. Gaster with Gt 1 black with blue tinges, remaining tergites black; gonoplac black.
Antenna with solid clava. Face below level of toruli with weak reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a very weak median groove in posterior one-third, and with ten scattered adnotaular setae. Mesoscutellum with strong reticulation on median part and isodiametric meshes, lateral parts with strong reticulation, meshes elongate; submedian grooves indistinct, straight and diverging towards posterior part; with three setae scattered over lateral parts. Dorsellum with strong sculpture, without median carina. Propodeum with a strong and wide median carina; with strong reticulation; callus with ten setae. Fore and mid coxae with weak reticulation, hind coxa with strong reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.
Petiole not visible. Gaster elongate; medio-basal Gt 1 with a strong transverse carina dorsally; tergites with strong reticulation, Gt 1-4 with a smooth median line.

Hosts. According to the label data this species was reared from Perasphondylia odoratum (Diptera Cecidomyiidae). This name does not appear in the most recent catalogue of Cecidomyiidae (Gagné & Jaschhof 2021); however, one of the host plants of P. reticulata Möhn is Chromolaena odorata (Asteraceae) so presumably the label refers to the bud gall induced by this cecidomyiid on this plant; P. reticulata is recorded from Bolivia as well as Brazil, El Salvador and Mexico.
Distribution. Bolivia.
Material examined.
Holotype ♀ BOLIVIA: Santa Cruz, v.1971, from Perasphondylia odoratum (NHMUK). Paratypes: 1♀ 2♂ with same label data as holotype (NHMUK).
Etymology. Named after the host.
