Diagnosis

The subspecies differs from the nominotypical subspecies mainly by the sternites of the abdomen, which are smooth at the middle. In addition, the antennomeres five to ten are elongate. The gonocoxites are less pointed apically.

Etymology

The name is a noun and refers to the city Medan in the North of Sumatra where many of the specimens were found.

Taxonomic remark

Kult already recognized the form as a new species. He added a red type label and a name to one of the specimens. However, the species was never described and the name was never published. The name provided to the specimen by Kult is therefore not valid.

Description

MEASUREMENTS. Holotype: body length 6.95 mm, width 2.08 mm; L/W of pronotum 0.99; L/W of elytra 1.84. Other material: body length 6.5–7.23 mm (ẍ: = 6.9 mm *), width 1.92–2.17 mm (ẍ: = 2.04 mm *), L/W of pronotum 0.95–0.99 (ẍ: = 0.98*), L/W of elytra 1.83–1.89 (ẍ: = 1.88*); (*n = 10).

The subspecies differs from the nominotypical subspecies mainly in the following characters:

HEAD. Antennomeres five to ten elongate (L/W around 1.3). Clypeal wing just traceable, not completely fused with lateral lobe.

PRONOTUM. Lateral margin with indistinct concave part in anterior half.

ELYTRON. Outline slightly more oval than in the nominative subspecies. Intervals at humerus and apex less intense reticulated. Reticulation restricted to intervals six to eight.

HIND WINGS. In all of the 18 female specimens available, the alae are fully developed.

LOWER SURFACE. Sternites of abdomen smooth at middle, glossy.

MALE GENITALIA. Unknown.

FEMALE GONOCOXITE AND EPIPLEURITE (Fig. 49). Epipleurite more elongated than in the nominative subspecies, with distinctly widened angulated rod.

Distribution

Known to occur in the North of Sumatra ( Indonesia).
