Glenea quadriguttata Pic, 1926 revised status, lectotype designation

Glenea 4-guttata Pic, 1926: 22. Type locality: Vietnam, Tonkin, Djang. Type depository: MNHN.

Remarks.

Breuning (1956) had previously treated Glenea quadriguttata as a subspecies of Glenea lacteomaculata . We have found the following morphological differences between them - Glenea lacteomaculata : vertex and occiput of the head with two separate, longitudinal vittae of white pubescence; punctures at the base of the elytra denser and more irregularly spaced than in Glenea quadriguttata ; central-most, white elytral maculae more slender, transverse and oblique; elytral apex without acute or toothed angles; - Glenea quadriguttata : head with vittae fused, not separate; central-most, white elytral maculae almost rounded; elytral apex with small sutural and outer apical teeth. With these differences, Glenea quadriguttata is reinstated as an independent species.

Distribution.

China (Guangxi, Yunnan); Vietnam (Tonkin).

Lectotype designation.

The original description does not allow to know the number of specimens used by Pic (1926). In order to fix the species concept and ensure universal and consistent interpretation of this species, we designate the female specimen with Pic’s handwriting labels as the lectotype (Fig. 12a, b), and the first author did not find another syntype to be paralectotype when she worked in MNHN in 2007-2008. The lectotype has the following labels: "Ha Djang/ (Tonkin)" handwritten, " Glenea quadriguttata Pic" handwritten, “type” handwritten on yellow label, "Breuning valiv" handwritten, “TYPE” printed on pink red label. And a lectotype label will be added by the managers in MNHN after this paper.
