( Figures 2 View Figure 2 , 3 View Figure 3 , 4 View Figure 4 A–I)

Diagnosis

Porphyrochroa sierra sp. nov. differs in having the distal region of the mid tibia and anterior region of the mid basal tarsomere gradually wider and in the the singular format of the sternite 6 projected posteriorly on sternite 7.

Description

Male. Body length 4.6 mm; wing length 4.2 mm. Head shiny brown, with metallic green lustre in diverse angles of incident light. Eyes dichoptic. Frons and face shiny brown. Frons slightly narrower than anterior ocellus width, subparallel-sided, with four proclinate setae. Face longer than frons and the same frons width. Proboscis light-yellow, length equal to height of head. Palpus light-brown, with one small and almost apical seta. Ocellar tubercule with vitreous yellow ocellus; two proclinate ocellar setae; two proclinate postocellar setae. Antenna brown, with conspicuous grey pruinescence; scape twice as long as pedicel; scape and pedicel medially verticillate; flagellum about four times longer than scape and pedicel combined. Postcranium shiny brown, with distinct brown setae and little grey pruinescence; a pair of proclinate vertical setae; postocellar setae distinct, with dorsal stronger. Gena and postgena with brown setae and grey and sparse pruinescence. Thorax shiny dark-brown, with metallic green lustre in diverse incident light angles and conspicuous postsutural grey pruinescence. Thoracic setae: 5 ktg; 4 ap sctl; 1 pprn; 3 prepst; 1 acr; 4 dc; 1 p spal; 1 spal; 1 pal; 1 npl. Fore end mid legs yellow with half of tibia and tarsi brown. Hindleg brown with trochanters yellow.

Terminalia: epandrium subtriangular ( Figure 4F View Figure 4 ). Hipandrium with setae posteroinferiorly with apex narrow ( Figure 4D,E View Figure 4 ). Cercus elongate ( Figure 4H View Figure 4 ); ejaculatory apodeme with three projections in anterior view ( Figure 4G View Figure 4 ); subepandrial sclerite with base longer than arms ( Figure 4i View Figure 4 ).
