TYPE MATERIAL. Holotype, male, with the following labels: white square (printed)

“South Kuriles, Kunashir Isl., between Rikorda River and Belozerskaya River, 24–30. V

2016, Yu. Sundukov leg.”, red square (printed) “ HOLOTYPUS Odacantha puziloi aino subsp. n. det. K. Makarov et Yu. Sundukov, 2019” [ ZIN]. Paratypes, with the following labels: South Kuriles , Kunashir Isl. , Veslovskii Peninsula, 1.5 km north of Cape Veslo ,

21.VII 2008, K. Makarov leg. [1 ex., MPU]; between Rikorda River and Belozerskaya River ,

24–30. V 2016 , Yu. Sundukov leg. [89 ex., ZIN, MPU, FEB]; ibid, 19.VIII 2017, Yu.

Sundukov leg. [1 ex., FEB] .

DESCRIPTION. Head with rounded temples, usually regularly tapering towards neck.

Eyes slightly smaller than temples (TEL/OCL ratio, 0.92–1.38, average 1.11).

Pronotum as in the nominative subspecies. Punctures on prosternum and proepisterna usually less strongly developed, the surface in front of coxae usually being smooth, less than

10% of individuals showing punctures there.

Elytra wider (ELW/ELL 0.50–0.56, average 0.52), markedly broadened in posterior part.

Their striae usually well-developed and reaching apices. Punctation variable, points often being quite large. Microsculpture similar to that of the nominative subspecies, but upper edge of cells more convex.

Aedeagus almost straight, in preputial field area markedly broadened, wider than in the nominative subspecies (EDW/EDL 0.14–0.17, average 0.16, n=11). Left paramere rounded trapezoidal, ca. 2 times as long as wide (LPW/LPL 0.41–0.52, average 0.49, n=11).

Body length 5.6–6.8 mm (average 6.2 mm, n=20). Measurements used here (n=27): OCL

– 0.38–0.48 (average 0.42); TEL – 0.40–0.55 (average 0.46); HEW – 0.95–1.10 (average

1.03); PNW – 0.75-0.93 (average 0.83); PNL – 1.03–1.23 (average 1.14); ELW – 1.58–1.89

(average 1.75; ELL – 3.05–3.63 (average 3.38).

DIAGNOSIS. Differs from the nominative subspecies by its relatively wide elytra, the weak punctures on the prosternum, the coarser punctures on the striae, and the more distinct microsculpture of the elytra. In addition, the aedeagus in O. puziloi aino subsp. n. is larger and thicker, while the left paramere is significantly wider ( Figs 26, 27, 34, 35 ).

DISTRIBUTION. Russia: South Kuriles (Kunashir Isl.). Not found on the islands of the

Lesser Kuriles (field studies of Yu. Sundukov on the islands of Shikotan, Yuri, Polonsky,

Tanfilyeva in 2012, 2016, 2017). The records from Japan (Habu, 1967, 1982) can refer to both nominative and new subspecies.

BIOLOGY. On the island of Kunashir, this form has only been found in the extreme south, along the shores of coastal wetlands and marshes ( Figs 46, 47 ).

and relative elytral width (EDW/EDL). paramere (LPW/LPL) and aedeagus (EDW/EDL).

Green – O. puziloi puziloi , red – O. puziloi aino subsp. n.; spots – female, circles – male; the asterisk denotes the lectotype and paralectotype. The differences between subspecies (t-test) are significant: p = 0.00041017 for TEL/OCL, p = 8.6047E- 12 for ELW/ELL, p = 0.00021324 for

LPW/LPL and p = 0.00014941 for EDW/EDL.
