This species was described on the basis of an unspecified number of specimens, of both males and females. Sack (1941) only refers to material of Q. fasciata from ‘Laristhal’, which means ‘Lares Valley’, Peru, belonging to Schnuse’s collection, and also to Peruvian material in the ‘Stettiner Museums’ collection. In Dresden Museum (SNSD) there were five specimens, a male and four females, from which the male and one female were identified as Myathropa fasciata , presumably by Sack, but these latter two were Bolivian specimens (the male is here described as Q. dissimilis sp. nov. and the female as Q. boliviana sp. nov.). Only one of the females, without an identification label, came from ‘Laristhal, Peru’ and belonged to Schnuse’s collection. This was the only specimen that matched the original description both in morphological characters (except for some trivial variation in leg colour) and locality data. As the other Peruvian type material of Q. fasciata seems to be lost, or was even destroyed during the 20 th century (the city of Stettin, Szczecin in Polish, was heavily damaged during World War II), we designate this Peruvian female as the lectotype of Q. fasciata .

Diagnostic features

Female (lectotype)

Head: Frons brown pollinose, with both black and light-brown laterally directed hairs intermixed; frons with a line of shorter, light-brown hairs on the eye margins; hairs on the dorsal area of the frontal prominence anteriorly directed; antenna red, only blackish on the basoflagellomere dorsally; basoflagellomere oval ( Fig. 11 View Figures 9–14 ); bf = 1.3; frontal prominence ventrally black, except for the red area surrounding the antennae; black face with white hairs, except for a central shiny bare stripe; the rest of the face covered with very sparse white pollinosity, except for the dense pollinosity on the eye margins; gena with a lateral densely pollinose stripe from the eye margins to the mouth edge.

Thorax: Scutum with two brown pollinose stripes faintly reaching the posterior margin of the scutum; scutum extensively pale haired, but with a few short black hairs on the area above the wing insertion; PAPT posterodorsally, NP, and PC with dense and conspicuous tufts of whitish yellow hairs; AEP with whitish yellow hairs; brown scutellum, black on the lateral corners; scutellum covered only with long yellowish hairs; anterior and posterior spiracles pale; the apical two-thirds of pro- and mesofemur, the full length of the pro- and mesotibia, and the pro- and mesotarsus red; apical third of metafemur red; metatibia red with black markings on the apical twothirds; metatarsus red; legs extensively pale haired, except for black hairs present on the following areas – the apical half of the profemur posteriorly, the protibia (scattered black hairs), the apex of the mesofemur posteriorly, the apical third of the metafemur ventrally, the apex of the metafemur dorsally, most of the length of the metatibia ventrally, and the apical half of the metatibia dorsally; wings extensively microtrichose; wings very lightly brown pigmented anteriorly.

Abdomen ( Fig. 77 View Figures 73–79 ): Tergum I with a moustache arrangement of whitish yellow hairs, with a central gap; terga II–IV each black with two lateral red markings, which extend from the anterior to the posterior margins in terga II–III, and only reach the anterior margin in tergum IV; terga II–III narrowly red on the full length of the posterior margin, even narrower in tergum III; terga II–IV extensively brownish pollinose except for the shiny band on the posterior margin of tergum IV; tergum V shiny except for an anterior narrow dull band; all other terga extensively covered with yellowish white hairs, except for black hairs on the following areas – posterior black areas of terga II–IV centrally and the posterior half of the lateral margins of tergum II (black hairs also on the posterior corners of tergum II); posterior margins of terga II–IV laterally fringed with adpressed yellowish white hairs; tergum V with long black hairs, but pale hairs anteriorly; sterna with long pale hairs; sternum V with scattered black hairs intermixed with pale hairs.

Taxonomic notes

Large species (13.4 mm) with broad abdomen ( Fig. 77 View Figures 73–79 ); Q. fasciata can be separated from the similar Q. hermosa by the following characters: in Q. fasciata the hairs on the NP, PAPT, PC, and tergum I are whitish yellow, the metafemur is red on the apical two-thirds, the protibia are red, the cells BM and CuP are wholly microtrichose, and tergum IV has red markings, whereas in Q. hermosa the hairs on the NP, PAPT, PC, and tergum I are white, the metafemur is extensively black, the protibia has a black marking on the apical half, the cells BM and CuP have some areas bare of microtrichia, and tergum IV is wholly black.
