Macrostomus limbipennis (Bezzi)

( Figs 6A–M View FIGURE 6 )

Rhamphomyia limbipennis Bezzi, 1909: 329 . Type locality: Peru, Pasco, Pichis, Puerto Bermudez .

Rhamphomyia (Lundstromiella) limbipennis: Melander, 1928: 183 .

Macrostomus limbipennis: Collin, 1933: 210 ; Smith, 1961: 54; 1967: 30 (cat.); Rafael & Cumming, 2004: 446 (cit.); Yang et al., 2007: 145 (cat.); Rafael & Cumming, 2012 (redescr.); Rafael & Marques, 2019: 273 View Cited Treatment (cit.).

Diagnosis. Male. Postgenal and antepronotal setae as strong as dorsal thoracic setae; cell dm slightly projected ( Fig. 6A View FIGURE 6 ); tergite 8 fused with sternite 8, humped with microspinulose expansion ( Figs 6B–C View FIGURE 6 ); epandrium ( Fig. 6D View FIGURE 6 ) with anterior and posterior lobes of the same height; anterior cercus ( Figs 6E, F View FIGURE 6 ) bearing a posterior protuberance, seen in lateral view ( Fig. 6G View FIGURE 6 ), and a wide mesial process of anterior cercus apparently connected medially, seen in posterior view ( Fig. 6H View FIGURE 6 ); median cercus ( Figs 6E, F View FIGURE 6 ) elevated, somewhat membranous with long setae; posterior cercus ( Figs 6E, F View FIGURE 6 ) widened distally; ventral projection of cercus ( Figs 6H, I View FIGURE 6 ) down and obliquely directed with elongated distal setae; dorsal hypoproctal lobe ( Fig. 6H View FIGURE 6 ) smaller than ventral hypoproctal lobe and transversely placed in relation to ventral lobe, both with slender setae; hypandrium ( Figs 6J, K View FIGURE 6 ) somewhat narrow, subequal in diameter along entire length, with biseriate row of setae placed at basal half, dorsal pair longer; ejaculatory apodeme ( Fig. 6J View FIGURE 6 ) with short dorsal lamella.

Female. Tergite 8 ( Fig. 6L View FIGURE 6 ) widened laterally, with distinct sulcus distally; sternite 8 ( Figs 6L, M View FIGURE 6 ) divided; genital fork ( Fig. 6M View FIGURE 6 ) as a small rod with apex slightly wider, with genital chamber highly sclerotized; spermathecal duct elongated, widened medially and with spherical spotted receptacle distally ( Fig. 6M View FIGURE 6 ).

Geographical records. Bolivia, Brazil, Ecuador, Peru.

Material examined. All specimens listed in Rafael & Cumming (2012) and the additional following specimens: PERU: Cuzco, Quincemil , 13–31.viii.[19]62, L. Pena, 780 m (4♂, 1♀ INPA) ; idem, 1–15.xi,[19]62, L. Pena, 700 m (8♂, 6♀ INPA) ; Pasco, Puerto Bermudez , 800 m, 6.xi.1984, M. Cooper (1♂ NHMUK) ; idem (1♀ NHMUK) ; Cuzco, Quincemil , 13º13′03.4″S – 70º43′40″W, 633 m, 23–31.viii.2012, sweep, JA Rafael, RR Cavichioli, DM Takiya (2♂, 3♀ INPA) GoogleMaps ; Quincemil, Pte la Cigarra , 13º08′27″S – 70º23′14″W, 350 m, 01.ix.2012, sweep, JA Rafael, RR Cavichioli (7♂ MUSM) GoogleMaps ; Quincemil, Rio Araza , 13º21′18″S – 70º53′27″W, 1000 m, 22–26.viii.2012, sweep, JA Rafael, RR Cavichioli (1♂, 2♀ MUSM) GoogleMaps .

Remarks. Unlike most species of Macrostomus , M. limbipennis is widespread in the Amazon Basin, with records from Bolivia, Brazil, Ecuador and Peru. The Brazilian specimens are from the western border of the country, bordering the Amazonian environment of the other countries and conspecific with Peruvian specimens.
