Diagnosis. This new Peromyia is classified in the P. caricis group ( Jaschhof 2017b: 65) for the flagellomeres have a single girdle of hair-shaped translucent sensilla ( Fig. 25 View FIGURES 24–27 ), and because of the presence of both a simple, subcylindri- cal gonostylus and an ovate tegmen with indistinct ventral shield ( Fig. 26 View FIGURES 24–27 ). A combination of genitalic characters is specific to P. lindstroemi , as follows. The slightly bent gonostylus is twice as long as wide ( Fig. 26 View FIGURES 24–27 , ↓ 3), without a lobe dorsobasally ( Fig. 27 View FIGURES 24–27 ); the tegmen is slightly constricted subbasally and broadly rounded apically; the ventral shield, of which only the posterior edge is discernible, extends almost to the tegminal apex (↓ 4); the broad, ventroanterior edge of the gonocoxal synsclerite is somewhat angular (↓ 5); and below the ventral gonocoxal emargination is a large, membranous area of subtriangular shape. Females and preimaginal stages of this new Peromyia are unknown.
Other male characters. Body size 0.9 mm. Head. Postfrons non-setose. Eye bridge 2–3 ommatidia long dorsally. A single row of 8 postocular bristles. Neck of fourth flagellomere longer than node ( Fig. 25 View FIGURES 24–27 ). Palpus short, 4 segments successively decreasing in length. Wing. R 1 twice as long as Rs. Anterior portion of C extends beyond R 5 for once the vein width. Legs. Claws toothless. Genitalia ( Fig. 26 View FIGURES 24–27 ). Ninth tergite interrupted medially. Dorsal gonocoxal bridge broadly rounded anteriorly. Tegmen without microtrichose lobe ventrally (which is usually present in species of the caricis group).
Etymology. This species is named to honor Mattias Lindström, of Länsstyrelsen Hallands län (Halmstad, Swe- den), an enthusiastic explorer of nematocerous Diptera diversity and ecology, and collector of the holotype specimen of this new species.
