Etymology. – The specific epithet is dedicated to Jennifer De Almeida of the Insectarium de Montréal ( Canada) for her collaboration and many professional courtesies.

Remarks. – Lasiolepturges dealmeidae sp. nov. is similar to L.zikani Melzer, 1928 ( Fig. 38- 41), but differs as follows: antennae distinctly longer in both sexes, especially in males (longer than 3.5 times elytral length); antennomere III in males distinctly longer than humeral width; lateral tubercles of prothorax distinct; and elytra without erect setae on wide central area ( Fig. 34 -35).In L. zikani , the antennae are shorter in both sexes ( Fig. 38) (in males, distinctly shorter than 3.0 times elytral length), antennomere III in males about as long as humeral width, lateral tubercles of prothorax absent or slightly distinct, and elytra have erect setae throughout ( Fig. 39- 41).
