Description. Wingspan ♂ 37 mm, (forewing length ♂ 17–20 mm) ( figs 84, 85). Antennae bipectinate in males (female unknown). Frons rather flat, projecting about one quarter diameter of eye, smoothly scaled. Chaetosemata present as two small patches. Labial palpi about the size of eye diameter. Proboscis absent. Ground colour of wings brown, intermixed with dark brown scales, basal and medial areas slightly darker. On both wings antemedial line faint; postmedial line dark brown; postmedial line on forewing slightly angled outwards between M1-M2. Underside of wings unicolorous, light to dark brown, postmedial line partially visible. Terminal line dark brown. Discal spot black, more prominent on hindwing.

In male genitalia ( figs 123, 124 View FIGURES 120-126 ) uncus long, basally broad, medially curved, apically pointed. Gnathos strongly sclerotized, tongue-shaped. Saccus wide,anteriorly flat. Costa of valva strongly sclerotized, straight, apically broad and spinose, exceeding apex of valva. Ampulla superior broad, slightly curved, apically spinose; ampulla inferior narrow, half length of ampulla superior. Juxta anchor-shaped, stalk very thin, apical part extended. Aedeagus long and narrow (width-length ratio 1:11), cornutus one third length of aedeagus.

Female genitalia. Unknown.

Diagnosis. The type locality of the new species is in Israel, where only N. amygdalaria   is (co-)distributed, but due to their wing pattern and colour these species cannot be confused. The wing pattern and coloration of N. convergata   sp. nov. overlaps with that of N. divergaria   and N. eberti   sp. nov. ( figs 52–85). Although the last two species are not yet reported from Israel, here we present a differential diagnosis for their male genitalia: In N. convergata   sp. nov. costa of valva basally narrow, apically clubbed, exceeding apex of valva (costa of valva basally and apically narrow, digitiform, reaching slightly over apex of valva in N. eberti   sp. nov.; costa of valva basally and apically wide, reaching apex of valva in N. divergaria   ) (see figs 113–123 View FIGURES 108-114 View FIGURES 115-118 View FIGURE 119 View FIGURES 120-126 ). N. convergata   sp. nov. with ampulla superior digitiform, twice as broad as ampulla inferior, both ampullae located at the centre of valva (ampulla superior twice as broad as ampulla inferior, both ampullae located in the distal half of valva in N. eberti   sp. nov.; ampulla superior very long and broad, ampulla inferior highly variable, both ampullae located at the centre of valva in N. divergaria   ) (see figs 113–123 View FIGURES 108-114 View FIGURES 115-118 View FIGURE 119 View FIGURES 120-126 ). N. convergata   sp. nov. with long and narrow aedeagus; cornutus-aedeagus ratio 1/3 (aedeagus thick and strongly curved, cornutus-aedeagus ratio 2/ 3 in N. divergaria   ; aedeagus thick and slightly curved, cornutus-aedeagus ratio 1/ 2 in N. eberti   sp. nov.) (see figs 113–123 View FIGURES 108-114 View FIGURES 115-118 View FIGURE 119 View FIGURES 120-126 ).

Phenology. Univoltine late spring species. From May to early June.

Biology. Unknown.

Habitat. Montane. Dry rocky or stony slopes with scattered steppe vegetation. From 500 up to 2200 m (Mt. Hermon, upper cable station).

Distribution. So far only collected on Mt. Hermon and on Golan heights (map 1). The unclear record of ‘ Nychiodes   (?) divergaria   ’ in Wehrli (1934) for ‘Haifa’, may belong here, too, but the occurrence in the Carmel requires further confirmation.

DNA barcoding. Genetically homogeneous in the Levant (n=2 from Israel). Nearest species (minimum pairwise distances): N. eberti   sp. nov. (3.3%) ( fig. 145 View FIGURE 145 ).

Etymology. The name alludes to the species name of its sister species N. divergaria   , and to the latin verb convergere = to agree with.
