Figs 14 , 45, 53

Diagnosis

The subspecies differs mainly from the nominotypical subspecies by the additional blunt carina in front of the clypeal sulcus, by the not completely fused lateral lobe of the clypeus with the wing, by interval eight, which is reticulated by half of the width of the interval, and by the more distinctly advanced anterior angles of the pronotum.

Etymology

The name is a noun and refers to the type locality of the subspecies, Kotte, near Colombo in the West of Sri Lanka.

Type material

Holotype

SRI LANKA • ♀; with labels and data: white, handwritten in black ink “Kotte Ceylon At Light 30-XI-21 ” / white, printed “Colombo Museum.” / white, printed “ H.E.Andrewes Coll. B.M.1945-97.” white, printed and handwritten in black ink “ Clivina striata Putz. H.E.Andrewes det.”; NHMUK.

Remark. The right front leg is broken and the claws of the left hind leg are missing.

Description

MEASUREMENTS. Holotype: body length 6.53 mm, width 1.84 mm; L/W of pronotum 1.04; L/W of elytra 1.92.

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

HEAD. Clypeus with blunt carina in front of sulcus, sulcus undulated. Wing of the clypeus traceable, visible by slight convexity and slight notch between wing and lateral lobe. Impression on the frons of the head more elongated, appearing as being two impressed diverging lines.

PRONOTUM. Base of pronotum longer, narrow. Anterior angles distinctly acutely advanced, anterior transverse line reaching anterior margin at declivity, disk basolaterally with group of few impressed punctures of moderate size, with paramedian circular group of punctures in basal half. Proepisternum distinctly visible in dorsal view.

ELYTRON. Striae one to three distinctly punctate up to apex. Intervals more distinctly convex as in the nominate subspecies. Reticulation on interval eight covers only half of width of the interval.

HIND WINGS. The alae fully developed (only HT available).

LOWER SURFACE. Sternites of abdomen laterally covered completely and densely with moderately large punctures, smooth at middle but with microscopic punctures, apical segment with dense moderately large punctures surrounding margin, smooth at middle.

MALE GENITALIA. Unknown.

FEMALE GONOCOXITE AND EPIPLEURITE (Fig. 45). Gonocoxite partly hyaline, foliform, long-narrowed basally, flattened dorsally and ventrally, with one long nematiform setae positioned at the median side, with two preapical long nematiform setae preapically and one very long nematiform seta at apex. Epipleurite nearly square, with conspicuously widened angulated rod.

Distribution

Known from the type locality Kotte, Sri Lanka.
