DIAGNOSIS. Neocollyris (Isocollyris) ornata sp. n. seems to be especially similar to both N. (I.) apiceflava Dheurle, 2017 and N. (I.) sharovae Matalin, 2021 .

From the former species, N. (I.) ornata sp. n. is clearly distinguished by the mostly larger size (TL – 9.1–11.7 mm), vs. smaller (TL – 9.0–10.3 mm) in N. (I.)

apiceflava; the shape of the labrum with three prominent, frontal, central teeth (Figs

7–8), vs. not prominent in N. (I.) apiceflava ( Fig. 9 ); the longer (EL/PL – 2.56–2.86)

and narrower (PL/PW – 2.63–3.13) pronotum ( Figs 1, 2, 4, 5 , 16, 17, 19, 20 ), vs.

shorter (EL/PL – 2.88–3.10) and wider (PL/PW – 2.33–2.56) in N. (I.) apiceflava

( Figs 3, 6 , 18, 21 ); the bright green or bluish green elytra ( Figs 1, 2, 4, 5 , 25, 26, 28,

29), vs. dark blue, cobalt-blue or blue-green in N. (I.) apiceflava ( Figs 3, 6 , 27, 30 );

the mostly longer aedeagus (AL – 2.0–2.15; EL/AL – 2.8–3.12) with a wider inner basal side and a longer apex ( Figs 31–33 ), vs. a mostly shorter aedeagus (AL –

1.95–1.96; EL/AL – 2.97–3.03) with a narrower inner basal side and a shorter apex in N. (I.) apiceflava ( Fig. 34 ).

From the latter species compared, the females of N. (I.) ornata sp. n. are easily recognized by the longer (LW/LL – 1.67–2.0) and bicoloured labrum ( Figs 7, 8 ), vs.

shorter (LW/LL – 2.08) and entirely yellow in N. (I.) sharovae ( Matalin, 2021: fig.

2); the longer and narrower (PL/PW – 2.63–2.88) blue or blue-violet pronotum

( Figs 1, 2, 4, 5 , 16, 17, 19, 20 ), vs. shorter and wider (PL/PW – 2.50), and bright green in N. (I.) sharovae ( Matalin, 2021: figs 1, 5–6); the narrower shoulders (EW/

EHW – 1.41–1.50), vs. wider (EW/EHW – 1.37) in N. (I.) sharovae ; the bilobed humerobasal spot and the mostly narrower and duller yellow elytral maculae (Figs

1, 2, 4, 5, 22, 23, 25, 26, 28, 29), vs. three-lobed humerobasal spot and clearly wider and brighter yellow elytral maculae in N. (I.) sharovae ( Matalin, 2021; figs 1,

6, 7); the stout and more widely spaced apical spines of sternum VIII ( Fig. 35 ), vs.

slender and more narrowly spaced in N. (I.) sharovae ( Fig. 36 ).

ETYMOLOGY. The name of the new species is derived from the Latin “ ornata ,

-us ” – decorated, because of its bright colouration.
