Type material examined: Syntype ♀: " Sinai W. Isla, 28.2.1933, A. Schatzmayr / Syntypus ♀ Pinophilus schatzmayri Koch, rev. V. Assing 2012 / Pinophilinus schatzmayri (Koch), det. V. Assing 2012" (NHMB).
Comment: The original description is based on two female syntypes from "Wadi Isla, 28.2.1933 (Süd-Sinai)" (KOCH 1934). One of the type specimens was located in the Frey collection, which is currently housed in the NHMB. This species is characterized particularly by its large size (total length 7.5 mm; length of forebody 3.4 mm), palereddish coloration, long and slender antennae (2.1 mm) with distinctly oblong antennomeres I-IX, and by the dense and coarse punctation of the whole body, particularly of the abdomen. The habitus, the forebody, and the abdomen of the examined syntype are illustrated in Figs 6-8.

The chromosomes set of the species is 2n = 8. The chromosomes AB and CD are metacentric, the chromosome EF is submetacentric, the small chromosome G is telocentric (Fig.1). The centromeric regions of all chromosomes are dark bands, determined by the comparative analysis with the polytene chromosomes of the species presented by Kiknadze et al (2016). The “basic” sequences are located in the telomeres of the chromosome arms C, D, close to the telomeres of arms A and F and in the middle of arms B and E. Markers of the G chromosome are the Nuclear Organizer (NOR) and three Balbiani Rings (BRs) (BRa, BRb, BRc), as the BRa is not always expressed. NOR is located near the centromere separated from it by a dark band. The polytene chromosomes of the species were used to trace the impact of pollutants on the genomic characterization of the species by Ilkova et al. (2007). Seventy-three individuals were studied.

Chromosome set of the species is 2n = 8. Chromosomes AB, CD are metacentric, EF—submetacentric and G— telocentric. The “basic” sequences are located on the same part of the chromosome arms as that of C. piger (Fig.2). The centromere regions of the chromosomes occur as dark, large prominent bands with exception of a centromere region of chromosome G (Fig. 2). Chromosome G is very small and has one NOR and one BR. The marker of the chromosome is the two dark bands between which there are several lighter ones (Fig.2). A slightly polymorphous species (Michailova 1989). Five individuals were studied.
Collection sites: Varna, Sofia: South Part, larvae found in temporary water basin.

Chromosome set of the species is 2n = 8. Chromosomes AB, CD are metacentric, EF—submetacentric and G— telocentric. The species has four NORs: in chromosome arms A, C, E and arm G (Fig.3). Chromosome arm A has an inverted chromosome sequence A2.2. The “basic” sequences are located in the middle of the arm, next to NOR (Fig. 3). All other “basic” sequences are as in C.piger. Species markers are the three BRs located in the shortest chromosome G, one of which is located at the telomere and the other two are after the NOR. The series of dark and light bands between the BR and NOR of the chromosome G is a marker for the species. A high genomic instability was found in the species inhabiting regions highly polluted with heavy metals (Michailova et al. 2018). Seventy-two individuals were studied.

The species has 2n = 8. AB and CD chromosomes are metacentric, EF—submetacentric, G—telocentric. The centromere regions of all chromosomes are well identified (Fig. 5). The band sequences in arm A are in an inverted state (A2.2). The smallest chromosome, G has three BRs and one NOR, one of the BR is not always expressed. The NOR and two BRs are situated at both ends of the chromosome. The chromosome has partial incomplete conjugation of the homologues. A chromosome marker is the two dark bands of chromosome G with several light ones in between (Fig. 5). A high chromosomal polymorphism, appeared by homo- and heterozygous inversions, was found in the polytene chromosomes of the species from areas after Chernobyl nuclear power events, a highly radioactive area near Kyiv (Petrova & Michailova 1996). An additional B chromosome is reported for the first time in a species from this region (Michailova & Petrova, 1994). One hundred and forty-six individuals were studied.

The chromosome set is 2n = 8.AB and CD chromosomes are metacentric, EF—submetacentric and G chromosome— telocentric. The centromeric regions are dark thin bands, well defined (Fig. 6). A chromosome G has one NOR, near to the centromere and two BRs. The species is homosequential to Chironomus plumosus (Linnaeus) and distinguished by shape of its hypopygium (Michailova 1994). In Russian populations of the species, an additional B chromosome, characteristic of the genome of the species, was found (Kiknadze et al. 2016; Petrova & Zhirov 2022), but in the studied Bulgarian population such an additional chromosome was not found. It is characteristic of the species that chromosome G has incomplete conjugation almost throughout the chromosome, only in the area of the NOR homologues have conjugated (Fig. 6).In the middle of this chromosome there is a group of dark bands—makers of the species. Thirty-five larvae were examined.

The chromosome set is 2n = 8. Two chromosomes AB and CD are metacentric, EF—submetacentric and G chromosome is telocentric. The centromere regions of all chromosomes are distinct (Fig. 11). The arm A is with inverted sequences (A2.2). The species has four BRs—three in chromosome G and one in chromosome arm B. The homologues of chromosome G are unpaired. The NOR of chromosome G is near to the centromere region. Between the BR, located near to the NOR and the other BR there is a narrowing of the chromosome and many dark and light bands (Fig. 11)—markers of the species. The species is highly polymorphous, characterized by the presence of a polymorphous system of inversions which involved the transition of a standard homozygous type of the karyotype through heterozygotization into another homozygous type (Michailova 2014). This author reported for an additional B chromosome in Bulgarian populations (Fig. 11). Four hundred and two individuals were studied.

The chromosome set is 2n = 8. AB and CD chromosomes are metacentric, EF—submetacentric G—telocentric. The centromeric regions of all chromosomes are distinct large bands (Fig. 12). The polytene chromosomes of the species have the same band sequence as that of C.piger. They both species are homosequential. The localization of the “basic” sequences in every chromosome arm of the polytene chromosomes is the same as that of C. piger. The markers of chromosome G are the same as that of C. piger. The species is a model species for studying the influence of various environmental pollutants on the genome structure (Michailova et al. 2012, 2022; Duran et al. 2012). Since the species is easily grown in laboratory conditions, studies were conducted on the influence of various heavy metal ions in different concentrations on the structural-functional organization of its polytene chromosomes (Michailova et al. 2006). Deletions of BRb and BRc and formations of “pompon” chromosomes G were found only in larvae from the trace metal polluted stations—a good marker for environmental pollution (Michailova et al. 2022). In the C. riparius larvae from Pancharevo Lake, living in sediments containing high concentrations of Cu, Pb and Zn, salivary gland cells containing somatic rearrangements appeared at a significantly higher frequency (51.92%) (Ilkova et al. 2007). One hundred and fifty-four individuals were studied.

Chromosome set is 2n = 8. Chromosomes AD, BC are metacentric, chromosome EF—submetacentric, chromosome G—telocentric (Fig. 21). The centromere regions of the chromosomes are the dark thin bands. Chromosome arms A and E have NORs—a marker of the species. There is slightly expressed BR in chromosome arm B. Another marker of the species is the ectopic pairing between different chromosome arms. The chromosome arm F with inverted sequences (F2.2). No NOR in chromosome G, and only one BR. The homologues of chromosome G are pared except for a small section near to the centromeric region. A marker of the species is the narrowing in the middle of chromosome G, on both sides of which there are two dark bands, between which several lighter and dark ones (Fig. 21).
The polytene chromosomes of C. bernensis are very sensitive to pollutants and numerous somatic chromosome alterations were identified (Michailova et al. 2016). These authors found for first time an additional B chromosome in a species from a polluted region. Kiknadze et al (2016) reported for different heterozygous inversions in all chromosome arms.
