The Shannoni complex, comprising sand flies belonging to the subgenus Psathyromyia (Psathyromyia) Barretto, consists of several species, of which the females have banana-shaped spermathecae and the males have digitiform parameres on the terminalia. Among these species, Psathyromyia shannoni (Dyar) and two taxa considered as its junior synonyms (Phlebotomus limai Fonseca and Phlebotomus bigeniculatus Floch & Abonnenc), Psathyromyia pestanai (Barretto & Coutinho), and a new species are the focus of this study. On the basis of morphological and morphometric characters, Psathyromyia bigeniculata (Floch and Abonnenc) stat. rev.; comb. n. and Psathyromyia limai (Fonseca) stat. rev.; comb. n. are resurrected from the synonymy of Pa. shannoni. Pa. pestanai is proposed as a new junior synonym of Pa. limai. Psathyromyia ribeirensis sp. n., occurring in the middle and upper Ribeira Valley in the state of São Paulo, Brazil is described. Pa. limai, described from the Serra da Cantareira (São Paulo municipality) and also found in the lower Ribeira Valley and on the adjacent coastal plain, is morphologically very close to the new species.
沙氏复合体，包括属于亚属 Psathyromyia（Psathyromyia）的沙蝇，由几个物种组成，其中雌性具有香蕉形的受精囊，雄性具有末端的指状副叶。在这些物种中，沙氏沙蝇（Dyar）和两个被认为是其同物异名的分类群（利马氏蚋蝇和双节蚋蝇）、佩斯塔奈沙蝇（Barretto 和 Coutinho）以及一个新物种是本研究的重点。基于形态和形态特征，重新确立了大双节蚋蝇（Floch 和 Abonnenc）的状态；并将利马氏蚋蝇（Fonseca）的状态恢复为同物异名。佩斯塔奈沙蝇被提议为利马氏蚋蝇的新同物异名。在巴西圣保罗州的中上游里贝拉山谷发现了一种新的沙蝇，名为里贝朗普斯蝇。从坎塔雷拉山脉（圣保罗市）描述的利马氏蚋蝇，也在下游里贝拉山谷和相邻的沿海平原发现，其形态与新种非常接近。
