Parapyrellia oportuna Albuquerque & Lopes, 1979: 327. Type locality: BRAZIL, Mato Grosso, Sinop, 12o31'S, 55o37'W. Holotype Ƌ, MNRJ (seen).
Redescription. Colour: Black, with green reflections. Frontal vitta and fronto-orbital plate shining black; face and lower half of parafacial brown with silver pruinosity; rest of parafacial, face and inner portion of gena light brown with white pruinosity; outer portion of gena shining brown; antenna yellow; palpus yellow; mesonotum metallic black with a slight green reflection and with one silver-dusted central vitta in front of the acrostichals; legs brown; haltere and calypters whitish, upper calypter on outer half white and opaque; wing yellowish, with dark markings from Sc apex to tip of R1 and down to R2+3 apex, and on r-m and dm-cu cross-veins. Abdomen without pruinosity.
Male. Body length: 4.0–5.0 mm; wing length: 4.0– 4.5 mm.
Head. Eyes bare, separated at level of anterior ocellus by 0.24–0.25 of head width; frons divergent towards lunule; ocellar triangle with a pair of setae and a few setulae; 10–11 pairs of frontal setae; postpedicel about 2.25 times the length of pedicel; pedicel with 1 seta and a few setulae; arista plumose, with 8–11 cilia, bare apicad, and with no secondary plumes; vibrissa shorter than arista; 1 supravibrissal seta, and a few setulae that extend to level of middle of postpedicel; 4 subvibrissal setae followed by 9–10 genal setae. Palpus expanded at apex.
Thorax. No acrostichals; dorsocentrals 0+2; intra-alars 1+0; presutural 1; prealar 1, strong; supra-alars 2 (anterior very short); postpronotals 3; notopleuron with 2 long, subequal setae and covered with ground-setulae; postalars 2; no intrapostalar; scutellum with 1 basal, 2 latero-discal and 1 apical pairs of setae, and latero-ventrally with many setae, the basalmost ones downcurved; postalar wall and suprasquamal ridge with short pile; proepisternal depression bare; proepimeron with some short setulae; prosternum broad and bare; anepisternum with a posterior row of about 7 setae, without upcurved setae on upper-anterior corner, and covered with setulae; katepisternals 1+1 (the anterior one very small in some specimens); anepimeron extensively setulose; katepimeron with 1 setula; anatergite bare; katatergite setulose. Legs: fore femur with a posterodorsal row of setae, and a complete posteroventral row of setae; fore tibia with a dorsal row of short and strong setae, a posterodorsal row of setae, many setulae on ventral surface, and 1 dorsal, 1 posterodorsal and 1 posteroventral preapical setae; fore tarsus with some long setae on basal segment; mid femur without a tubercle, with 6 ventral setae on basal third, and 2 posterior to posterodorsal preapical setae; mid tibia with 3 strong posterior setae on middle third, and 1 anteroventral, 2 anterior, 2 posteroventral and 2 ventral apical setae; hind femur with an anteroventral row of setae; hind tibia with many long anteroventral-posteroventral setae, an anterodorsal seta on middle third, a dorsal row of short but strong setulae, 1 dorsal and 1 anterodorsal preapical setae, 1 anteroventral and 1 posteroventral apical setae, and a posterior brush-like ctenidium; hind tarsus with very strong setae ventrally (formed by the agglutination of many setae). Wing (Fig. 190) with a uniform covering of microtrichia; dm-cu sinuous; stem-vein bare before, and with 5 short setulae after, humeral cross-vein on dorsal surface, and ventrally with about 2 short setulae before humeral cross-vein; R2+3 bare on dorsal and ventral surfaces; R4+5 setulose from base to beyond r-m on dorsal surface and bare on ventral surface; 1–2 strong setae on basicosta.
Abdomen. With a few normal setulae on tergites; sternite 1 setulose; posterior margin of sternite 5 concave and with a few setae on membrane (Fig. 191).
Terminalia. Aedeagal apodeme narrow; aedeagus with spicules on anterior membrane of distiphallus; gonopod with 1 long and strong seta on basal third; paramere large with 2 setae on apical half (Fig. 192) (only part of the terminalia was drawn because the holotype slide was in bad condition and the male paratype was without its abdomen).
Female. Body length: 4.0 mm; wing length: 3.5–4.0 mm.
Similar to male, differing as follows: lower half of frontal vitta and fronto-orbital plate shining black and upper half of parafacial yellow; eyes separated at level of anterior ocellus by 0.33–0.37 of head width; fronto-orbital plate with 2 proclinate setae and 1 reclinate setula; hind tibia without many anteroventral-posteroventral setae but with 2 anteroventrals on middle third; hind tarsus without modifications.
Ovipositor. Tergite 6 shaped as 2 golf-club-like rods; tergite 7 as 2 rods, posteriorly with 2 small plates with setae; tergite 8 as 2 rods, posteriorly with 2 narrow plates with many small setae, two of them long; sternite 6 as 1 very small plate; sternite 7 as 3 small plates with spines; sternite 8 as 2 small plates with spines; epiproct triangular, incised anteriorly, with many very small spines; hypoproct with many setae; cercus cylindrical and long (Figs 193– 194).
