QUICHUANA PARISII CERESA, 1934: 389

FIGURES 44 AND 82

Five females were examined by Ceresa (1934), four of which comprise the type series. These four specimens are deposited in MCSN. Each specimen of the type series is red-labelled as ‘cotypus’ with the letters ‘co’ crossed out. Although the specimens were collected in ‘S. Paulo, S. Sebastiaõ ( Brasile)’ ( Ceresa, 1934), the actual specimens are labelled as collected in ‘S. Paulo’. We designate a lectotype and three paralectotypes to stabilize the name (see ‘Material examined’).

Diagnostic features

Female

Body extensively black ( Fig. 82 ), although sometimes copper; frons and face shiny black, with a narrow band of white pollinosity on the eye margins; ocellar triangle with dark-brown hairs; bf = 1.2 (lectotype) ( Fig. 44 ); face with white hairs, except for a central bare stripe extending from the antennae to the mouth edge; facial tubercle conspicuous; scutum with lightyellow hairs and, on PP and the area above the wings, black hairs; pleuron with long black hairs on AEP; tufts of hairs absent on scutum and pleuron, only PAPT posterodorsally with a denser group of lightyellow hairs; legs extensively black; wings extensively microtrichose, with a characteristic pattern of pigmentation – anterior half of the wing with cells and veins yellow pigmented on the basal half and darkbrown on the apical half ( Fig. 82 ); tergum I with a moustache arrangement of sparse light-yellow hairs ( Fig. 82 ); terga wholly covered with light-yellow hairs, especially longer on the lateral margins of tergum II anteriorly and the lateral margins of tergum V.

Male

Unknown.

Taxonomic notes

Small to medium size species (10.5 mm, lectotype) with moderately broad abdomen ( Fig. 82 ); the only similar species is Q. invenusta sp. nov., from which Q. parisii can be separated following the ‘Taxonomic notes’ under Q. invenusta sp. nov.
