Cercyon (Cercyon) quisquilius ( Linnaeus, 1761)

( Figs 7 View Fig , 13 View Fig )

Scarabaeus quisquilius Linnaeus, 1761: 138 . Transferred to Cercyon by STEPHENS (1829: 153).

Cercyon guangxiensis Wu & Pu, 1995 in JIA et al. (1995:128).Synonymized with C.quisquilius by JIA et al. (2011:48). For complete synonymy see HANSEN (1999).

Type locality. Sweden.

Type material. Scarabaeus quisquilius : SYNTYPES: The species was described from Sweden based on an unspecified number of specimens. Based on the on-line catalogue of the Linnaeus collection, there are two pinned specimens present in the collection, one with labels ‘83 [p] // quisquilius’, the second without any label data. We consider both these specimens as syntypes. Based on the photographs available on-line, both correspond well with the European specimens treated under the name Cercyon quisquilius by the body form and coloration (yellow elytra, dark pronotum with pale lateral sides).

Lateral margins of pronotum with narrow bead overlapping anterior and posterior corners, anterior and central part of posterior margin of pronotum without bead. Prosternum with strong longitudinal carina medially; antennal groove distinct, moderately large, rounded laterally. Mesoventral plate narrowly elongate, ca. 5.5–6.2× as long as wide, widest at midlength ( Fig. 7F View Fig ). Metaventrite with raised, glabrous, sparsely punctate median pentagonal area; femoral lines absent. Elytra with ten punctate striae, striae 1–9 impressed and reaching base, stria 10 very short; intervals flats, ground punctures on intervals very fine; humeral bulge indistinct. Epipleura flat, horizontal. Femora with sparse and shallow punctures ventrally, with distinct tibial groove. Tarsi with densely arranged whitish setae ventrally, first metatarsomere about as long as metatarsomeres 2–3 combined.

Abdomen. Abdomen with five ventrites, first ventrite distinctly longer than other ventrites, ca. 2× as long as second ventrite, bearing distinct median longitudinal carina, fifth ventrite arcuate, not emarginate apically.

Male genitalia ( Figs 7B–D View Fig ). Phallobase slightly longer than parameres, asymmetrical basally. Paramere rather wide basally, slightly sinuate on outer margin, asymmetrically rounded apically; apex membranous, with setae. Median lobe widest near apex, slightly narrowing towards base, with long ароdemes, apex triangular, obtusely pointed; gonopore small, situated subapically. Median projection of sternite 9 narrowly rounded apically, bearing 4 short subapical setae; base strongly arcuate, median portion shorter than lateral struts.

Variation. The species varies in size, but otherwise is very uniform across its range; in some specimens, the base of the metaventral pentagon is yellowish-red.

Biology. Polysaprophage. It inhabits mainly the excrements of mammals (cows, horses, sheep and others). It frequently occurs in compost, rotting plant debris, rotten mushrooms ( SMETANA 1978, 1988; NIKITSKY et al. 1996; RYNDEVICH 2004с, 2007). Some specimens were also collected in the nest of black stork Ciconia nigra ( Linnaeus, 1758) ( LUNDYSHEV & RYNDEVICH 2010) . The species comes frequently to light.

Distribution. The species is widespread in the whole Palaearctic Region and in North America south to Mexico. In Asia, it is recorded from ca. 62°N in Russia (Western and Eastern Siberia, Far East) south through Mongolia to China including its southern provinces (Gansu, Henan, Jiangxi, Inner Mongolia, Qinghai, Shaanxi, Sichuan, Guangxi, Shanghai, Yunnan), Japan (Hokkaido, Honshu and Kyushu) and Nepal, and through Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan) to Turkey, Iran, Israel and Syria; no records are known from northern and central Kazakhstan and from the proper Tibetan Plateau. Cercyon quisquilius is also introduced outside of its native range to the Pacific (Hawaii: HANSEN 1995), Australia (Fikáček, unpubl. data) and Neotropics (Argentina, Caribbean: FIKÁČEK 2009, ARRIAGA- VARELA et al. 2017). New for Chinese province of Anhui, Gansu, Guangdong, Hebei, Heilongjiang, Henan, Hubei, Jiangxi, Shaainxi, Sichuan and Yunnan, and for Kyrgyzstan, Turkmenstan, Syria and Iran.
