Cis matchanus Reitter, 1915 stat. nov.

( Figs 1–5 )

Reitter (1915) described Cis lineatocribratus v. matchanus , a variety of Cis lineatocribratus Mellié, 1849 on the basis of specimens from the current area of Bosnia and Herzegovina (Čelič), Romania, Georgia (Tbatani) and Azerbaijan (Talysh Mts.).

According to Reitter (1915), Cis lineatocribratus v. matchanus differs from the typical form in the sculpture of the elytra. Whereas in the typical form the rows of points on the elytra are coarse and deep and the interspaces are occupied by only a few, barely visible points and usually appear smooth, the rows of points in Cis lineatocribratus v. matchanus are somewhat less strongly and deeply pronounced but the spaces between them have dense and fine points. Thus, the sculpture of the elytra is more similar to that in Cis jacquemartii and Cis castaneus . But the coarser points on the elytra of these both species do not form distinct rows. Cis lineatocribratus v. matchanus has the clypeus with two teeth that are sharper than in the typical form. Its large, arched, laterally rounded pronotum, whose lateral margins are not visible from above, permits one to identify this form as Cis lineatocribratus .

From my examinations of specimens of the type series, including both external and male genitalia morphology ( Figs 3–5 ), I was able to conclude that the species is distinct from Cis lineatocribratus and conspecific with Cis hanseni Strand, 1965 . As a result, the following synonymy should be established:

Cis matchanus Reitter, 1915 stat. nov.

= Cis lineatocribratus v. matchanus Reitter, 1915: 66

= Cis hanseni Strand, 1965: 61 syn. nov.

An appropriate description of C. matchanus (under the name Cis hanseni ) was given by Strand (1965) along with the key to the determination of all European species related to Cis castaneus and drawings of details of the pronotum and male terminalia.

Type specimens studied (coll. HNHM). Lectotype by present designation: ♂, [p] Čelič, Bosn. Jar. Matcha. // handwritten text “ Matchanus m. lineatocribratus var.” // rectangular label with a red border, “ Holotypus ” printed in red and the handwritten text “ Cis lineatocribratus v. Matchanus Reitter 1915 ” // [p] Coll. Reitter—Fig. 1, original labelling: Fig. 5 . Paralectotypes: 1♂ 1♀, the same data as lectotype; 1♂, [p] Rumaenia Reitter // rectangular label with a red border, “ Paratypus ” printed in red and the handwritten text “ Cis lineatocribratus v. Matchanus Reitter 1915 ” // [p] Coll. Reitter; 1♀, [p] Caucasus Tbatani [18]79 Leder, (Reitter) // [the same label as in the previous paralectotype] // [p] Coll. Reitter; 2♂ 1♀, [p] Talysch Reitter. // [the same label as in the previous paralectotype] // [p] Coll. Reitter.

It should be noted that Reitter did not designate the holotype. In the late 1940s (O. Merkl, personal information), all syntypes of C. lineatocribratus v. matchanus and five other specimens from Reitter’s collection were marked with red framed labels, on which the words “ Holotypus ” and “ Paratypus ” were printed in red ink, whereas the name of the taxon, the name of the author and the year of description were written by hand.

I am not certain whether I managed to locate all the specimens belonging to the typical series because Reitter (1915) did not state the number of specimens which he used to describe the species. Fortunately, however, the specimens I was able to examine come from all the localities listed by Reitter in his paper of 1915. One male specimen is designated here as the lectotype in order to preserve nomenclatural stability. Among the five specimens not belonging to the type series and marked with a rectangular red-bordered label with “ Paratypus ” printed in red and the handwritten text “ Cis lineatocribratus v. Matchanus Reitter 1915 ” is 1♂ Cis jacquemartii Mellié, 1849 : Bosnien. Reitter. Leder. Coll. Reitter, det. A. Kompanzev, conf. RK. The data relating to the other four specimens are given below.

Distribution. Cis matchanus (as Cis hanseni ) has been recorded from Denmark, Finland, France, Germany, Norway, Poland, Russia (both the northern and southern parts of European Russia) and Switzerland ( Strand 1965, Królik 1999, Callot & Reibnitz 2008, Jelínek 2008, Reibnitz et al. 2013). It turns out that it is widely distributed in southern and eastern Europe ( Bosnia & Herzegovina, the Czech Republic, Italy, Romania, Ukraine), in Asia Minor ( Turkey) and the Caucasus ( Georgia), reaching the coast of the Caspian Sea at Mt. Talysh and Alborz ( Azerbaijan, Iran).

Based on previous reports and my own observations, this species occurs in northern Europe and in foothills and mountainous areas with warmer climates. It is found in the fruiting bodies of Fomes (Fr.) Fr. , sometimes lying on the ground, together with C. castaneus , C. jacquemartii and C. lineatocribratus , with which it can be confused.
