Figs 9–10
Diagnosis
Male: head without proclinate orbital setae; wings with vein R 1 bare; terminalia with epandrium orange, basiphallus and distiphallus fused dorsally without a dorsal membranous strip (Fig. 9D), and vesica with a superior and inferior projection, the superior one C-like in lateral view and the inferior one with pointed lobes (Fig. 9D–E).
Etymology
The species epithet ‘ jimi ’ (‘jim’ + ‘i’), masculine genitive, is given in honor of Jim O’Hara (CNC).
Type material
Holotype PERU • ♂, abdomen dissected and stored in a microvial with glycerin pinned under the specimen; “ La Huerta, Puno / Peru 3800 m. / 24-28.XI.1955 / L.E.

Description
Male (n = 1)
MEASUREMENTS. Length: 9 mm.
HEAD. Parafacial, fronto-orbital plate and postocular orbit dark brown with silvery pruinosity (Fig. 10A– C); facial ridge with setae on lower third; parafacial with row of setulae close to eye, similar in size to subvibrissal setae; frons about 0.32 head width at level of ocellar triangle; frontal vitta blackish (Fig. 10B–C); 9–10 well-developed frontal setae reaching level of apex of pedicel; rows of frontal setae parallel except anteriormost 3 divergent; reclinate orbital seta present, proclinate orbital setae absent; ocellar setae as developed as upper frontals; outer vertical seta 2 × as long as postocular setae; gena and genal groove with silver pruinosity (Fig. 10A, C); gena with black setae; postgena silvery-gray pruinose with black setae; antenna black (Fig. 10A, C); first flagellomere approximately 2 × as long as pedicel; arista micro pubescent on basal half (Fig. 10C); palpus blackish (Fig. 10A, C).
THORAX. Dark brown with silvery pruinosity (Fig. 10A–B); chaetotaxy: acrostichals 2 (anteriormost shorter) + 0, dorsocentrals 2+3, intra-alars 1+2, supra-alars 1+2, postpronotals 3, notopleurals 4; postalar wall bare; postalar callus with 2 setae; scutellum with pair of basal and pair of subapical setae, apical setae absent, and discal setae absent; katepisternum with 3 setae almost in straight line; meral setae 7–8; proepisternum bare.
WING. Hyaline, with dark brown veins (Fig. 10A–B); tegula dark brown; basicosta yellowish; vein R4+5 with setulae dorsally at ⅓ of distance to crossvein r-m; vein R1 bare; cell r4+5 open at wing margin; costal spine differentiated; third costal sector bare ventrally.
LEGS. Blackish-brown, pulvilli yellowish-brown (Fig. 10A); mid femur with 2 median anterior setae, row of anteroventral setae, 2 preapical posterior setae, row of posteroventral setae, and without ctenidium; mid tibia with 2 median anterior setae, 2 median posterior setae and 2 posterior setae in apical third; hind trochanter without ventromedian pad of short, spiniform setae.
ABDOMEN. Dark brown with silvery pruinosity; T4 with pair of median marginal setae and pair of lateral marginal setae; T5 with row of marginal setae; ST2–4 with marginal setae more developed than discal setae; ST5 with membranous window, arms approximately 2 × of base length, and dense setae pattern (Fig. 9A).
TERMINALIA. Syntergosternite 7+8 and apex of phallus black, other structures orange; cercus with numerous setae in basal half and sparse setae in apical half; cercal prongs divergent dorsally and rounded (Fig. 9B–C); surstylus almost rectangular, with apical setae (Fig. 9B); pregonite straight and longer than postgonite (Fig. 9D); postgonite with apex rounded and curved and short seta inserted on anterior margin in middle (Fig. 9D); postgonal apodeme short and oval (Fig. 9D); basiphallus and distiphallus fused dorsally without dorsal membranous strip (Fig. 9D); vesica with superior and inferior projection, superior one C-like in lateral view and inferior one with pointed lobes (Fig. 9D–E); juxta distinctly separated from paraphallus with median anterior projection (Fig. 9D); acrophallus formed by median stylus, median process, pair of lateral styli and pair of lateral processes (Fig. 9D–E); median stylus, median process, lateral stylus and lateral process almost straight with lateral stylus with spines in apex (Fig. 9D–E).
Female
Unknown.
Remarks
Microcerella jimi sp. nov. is morphologically similar to M. carchia Pape, 1990 but can be separated by the juxta being apically straight and its median anterior projection having a conspicuous spine in the apical half (Fig. 9D–E), whereas in M. carchia the juxta is apically bilobed and its median anterior projection has no spine (Lopes 1982: figs 56–58).
Distribution
Peru (Puna).
