Parapyrellia oportuna Albuquerque & Lopes, 1979: 327   . Type locality: BRAZIL, Mato Grosso, Sinop , 12o31'S, 55o37'W. Holotype Ƌ, MNRJ (seen). GoogleMaps  

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 View FIGURES 190 – 194 ) 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 View FIGURES 190 – 194 ).

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 View FIGURES 190 – 194 ) (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 View FIGURES 190 – 194 ).
