Phasmister kraliceki sp. nov.

( Fig. 10D, E )

Material: Kachin amber (c. 99 Mya). Amber piece dimensions: 11 × 9 × 1.5 mm. Amber clear with several insect fragments and air bubbles. Deposited at MEBHK ( P1424/E ) .

Dimensions. Head width: 0.42 mm; width between anterior pronotal angles: 0.55 mm; width between posterior pronotal angles: 0.9 mm; pronotal length: 0.5 mm; sutural elytral length: 0.8 mm; elytral width (in pair, across widest point): 1.15 mm.

Diagnostic description. The species is very similar to the recently described Phasmister hkamticus Caterino and Yamamoto, 2023 . However, it differs in several characters by which it can be distinguished. Pronotal disc lacks a short, curved costa in posterolateral corners; pronotal base more sinuate; anterior pronotal margin more broadly rounded, not crenulate and more emarginate above head.

Etymology: Named after Ivo Králíček, a good friend and biology tutor of J.S.P..
