Key for Psychodidae fauna of Fernando de Noronha

( Figs. 1–12 )

1 Ascoids with only the posterior branch, of variable shapes and number ( Figs. 1–3 ); terminal flagellomeres not reduced in size; last flagellomere with elongate apiculus ( Fig. 2 ); epandrial appendages with a group of several tenacula arranged from apical to subapical region ( Figs. 4, 5 ) ... Pericomaini ............................................................. 2

– Ascoids Y-shaped or ψ-shaped ( Figs. 6, 7 ); terminal flagellomeres reduced in size; last flagellomere without apiculus; epandrial appendages with very few apical tenacula—only one for Psychoda ( Fig. 8 ) ... Psychodini ............................ 3

2 Ascoids single-branched ( Fig. 3 ); wing vein R 5 ending beyond the apex ( Fig. 9 ); aedeagus with spines internally ( Fig. 4 ); epandrial appendages with eight tenacula.................................................... Telmatoscopus sp.

– Ascoids with two branches ( Fig. 2 ); wing vein R 5 ending in apex ( Fig. 10 ); aedeagus without spines ( Fig. 5 ); epandrial appendages with six tenacula............................................................ Clogmia albipunctata

3 Antenna with 13 flagellomeres and a pair of trident-shaped (ψ) ascoids ( Fig. 6 ); male terminalia with slender epandrial appendages about two times the length of epandrium; male abdomen with a group of dark setae on tergite 7; female subgenital plate with a pair of rosette-shaped ornamentation internally ( Fig. 11 ) ............................. Psychoda savaiiensis

– Antenna with 14 flagellomeres and a pair of Y-shaped ascoids ( Fig. 7 ); male terminalia with cub-like epandrial appendages smaller than epandrium length; male abdomen without a group of dark setae; female subgenital plate without internal rosette ornamentation ( Fig. 12 )................................................................. Psychoda buxoides
