– Elytra almost reaching middle of abdominal ventrite 3.

Dimensions (mm) (holotype ♀ / paratype ♂ / paratype ♀). – Total length, 9.50/6.30/6.85;

– Prothoracic length, 1.70/1.20/1.25;

– Anterior prothoracic width, 1.10/0.80/0.90;

– Posterior prothoracic width, 1.25/0.95/0.95;

– Maximum prothoracic width, 1.40/1.00/1.10;

– Humeral width, 1.65/1.15/1.25;

– Elytral length, 4.75/3.30/3.50.

Etymology. – T h e n a m e "a b b r e v i a t a " (f r o m L a t i n “abbreviatus" (shortened) refers to the shorter elytra, not covering the entire abdomen in either sex.

Remarks. – According to Santos-Silva et al. (2012), the elytra in Giesberteclipta are long and cover or almost cover the entire abdomen. Although the elytra distinctly do not cover the entire abdomen in both sexes of G. abbreviata , all other features of Giesberteclipta are present in this new species. Therefore, we reason that the species truly belongs in this genus. This feature allows separating the new species from all other species of the genus.
