Phyronota portensis Shannon & Del Ponte, 1926: 577
Lectotype designation of Phyronota portensis. Shannon & Del Ponte (1926) described Phyronota portensis from four females and seven males (syntypes) from Buenos Aires province, Argentina. The authors referred to "Adrogué, BA [Buenos Aires]" as type locality and pointed out that some specimens were captured “in copula” on September 12, 1926 by Dr. Eduardo Del Ponte. We located one male in ANLIS and three males in USNM. One male syntype is hereby designated lectotype of Phyronota portensis Shannon & Del Ponte, 1926. Lectotype male (ANLIS): in good condition, pinned, labels: “E. Del Ponte Coll [printed] / ♂ En copula [handwritten]” on white paper, black frame; “Adrogue (B A) [printed] / 12.9.26 [handwritten]” on white paper, black frame; “ Lectotype / Phyronota portensis / Shannon & Del Ponte, 1926 / L. D. Patitucci det. 2012” [red label, printed]. Paralectotypes in good condition (USNM): two males, pinned, labels: “E. Del Ponte Coll [printed]” on white paper, black frame; “Adrogue (B A) [printed] / 12.9.26 [handwritten]” on white paper, black frame; “ Paralectotype / Phyronota portensis / Shannon & Del Ponte, 1926 / L. D. Patitucci det. 2012” [red label, printed]. One male, pinned, in good conditions, labels: “E. Del Ponte Coll [printed]” on white paper, black frame; “Adrogue (B A) [printed] / 12.9.26 [handwritten]” on white paper, black frame; “ Phyronota / portensis / S & D P.” handwritten on white paper, “ Paralectotype / Phyronota portensis / Shannon & Del Ponte, 1926 / L. D. Patitucci det. 2012” [red label, printed].

Remarks. Psilochaeta chalybea was redescribed by Carvalho (1989), and presents a significant morphological similarity with Psilochaeta violescens (Dodge), endemic to Chile. This similarity is observed in their metallic coloration and terminalia morphology.
Biology. This species is associated with human envirounment (Figueroa-Roa & Linhares 2004). The specimens captured by authors were collected on decaying beef liver, chicken viscera, and dog faeces.
