Figs 6 , 27, 53

Diagnosis

The subspecies differs from the nominotypical subspecies mainly by interval seven hanging over laterally behind the humerus and covering interval eight nearly completely in dorsal view. In addition, the reticulation on interval eight is indistinct in general and covers only half of the width of the interval, and the lateral lobe of the clypeus is completely fused with the clypeal wing.

Etymology

The name refers to the reticulation on interval eight of the elytron which covers half of the interval by contrast to the nominate subspecies.

Type material

Holotype

INDONESIA • ♂; with two yellow labels, both handwritten in black ink and data: “ Java ” / “Reiche”; MNHN.

Remark. The left front leg and in the right front leg the four terminal tarsomeres are missing. The right elytron and the pronotum show pinholes and the pronotum a substantial crack. The specimen is very brittle and rotten inside.

Description

MEASUREMENTS. Holotype. Body length 8.83 mm, width 2.49 mm; L/W of pronotum 1.01; L/W of elytra 1.9.

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

HEAD. Clypeal wing completely fused with lateral lobe of the clypeus.

PRONOTUM. Lateral margin of pronotum nearly straight, slightly concave behind anterior setigerous puncture. Anterior transverse line more distinctly punctured than in the nominate subspecies.

ELYTRON. Interval seven hanging over laterally behind the humerus and covering interval eight nearly completely in dorsal view. The reticulation on interval eight covers only half of the width of the interval and is generally indistinct.

HIND WINGS. In the HT, the alae are completely missing.

LOWER SURFACE. Sternites of abdomen less densely punctured including the apical segment.

MALE GENITALIA (Fig. 27). The median lobe distinctly and long acuminated in the apical third, the apical lamella parallel sided.

FEMALE GONOCOXITE AND EPIPLEURITE. Unknown.

Distribution

Known from Java, Indonesia.
