Microhoria oertzeni oertzeni (Pic, 1901)

sensu Bucciarelli (1978) ( Figs. 21‒22 )

= Microhoria oertzeni sporadensis (Pic, 1901)

‘ Anthicus OErtzeni ’ – Pic 1901b: 181 (description: Samos).

‘variété sporadensis ’ – Pic 1901b: 181 (description: Samos).

Microhoria (Platyhoria) oertzeni – Bucciarelli 1978: 162 (informal new combination, taxonomy (new subspecies from Italy, M. oertzeni sicula ), record: ‘ Macedonia M. Athos’, Greece).

Microhoria oertzeni – Bucciarelli 1980: 217 (comparative diagnosis, type material); Uhmann 1985: 201 (records: Albania, Bulgaria); Uhmann & Guèourgiev 2000 (checklist for Bulgaria).

Microhoria oertzeni oertzeni – Chandler et al. 2008: 441 (new synonym of M. oertzeni var. sporadensis , checklist, distribution: Albania, Bulgaria, Greece, North Macedonia); Telnov 2020a: 611 (checklist, distribution: Albania, Bulgaria, Greece, North Macedonia).

104 Type material examined, M. oertzeni oertzeni . Syntype 1♂ MNHN ( Fig. 21B ): Samos, Marathokampos [printed] // type [handwritten] // TYPE [printed, label red] // Oertzeni Pic [handwritten]. Bucciarelli (1978: 217) reports a male holotype which should be read syntype, since M. oertzeni was described from unspecified number of specimens ( Pic 1901b).

Type material examined, M. oertzeni sporadensis . Holotype [monotypy] ♀ MNHN: Samos, Marathokampos v. Oertzen [printed] // coll. Reitter [handwritten] // type [handwritten] // v. sporadensis Pic [handwritten].

Additional material examined. 1♂ MSNM ( Fig. 21A ): ATHOS [handwritten] // Prop. microscp. No. [printed] 1062 [handwritten] [label blue] // A. Oertzeni Pic [handwritten] [label pale blue] [this specimen discussed and figured by Bucciarelli (1978, 1980).

Taxonomy. A male syntype of M. oertzeni oertzeni discussed herein was inspected by Bucciarelli (1980: 217). However, his concept of M. oertzeni is possibly incorrect. The studied syntype at the MNHN is remounted (glued on a rectangular paper card different from those used by Pic) and dissected, but the aedeagus was not available for the present study (moved or lost). The holotype of var. sporadensis (conspecific with M. oertzeni oertzeni ) is a female. Therefore, the comparison of male genitalia of the typical M. oertzeni from Samos (Aegean islands) with the drawing of aedeagus of the specimen from Mount Athos (mainland Greece) presented by Bucciarelli (1980) was not possible in our study. It also remains unclear why Bucciarelli (1978) did not figure aedeagus of the syntype but that of the specimen from Mt. Athos (maybe the cause was the lost-duringdissection aedeagus of the syntype). Additionally, we noted the following differences of significant importance between the studied syntype and holotype and the specimens of M. oertzeni sensu Bucciarelli (1978) from Mt. Athos: tempora somewhat converging posteriorly, rounded in one arc with head base (syntype M. oertzeni ) / tempora subparallel posterior to eyes, converging

Notes on Some Greek Microhoria Chevrolat, 1877 ( Insecta: Coleoptera : Anthicidae ) with New Descriptions and Synonymy posteriorly at rounded temporal angles, head base subtruncate or comparatively broader rounded (specimen from Mt. Athos); dorsal forebody glossy, punctures moderately large and dense (syntype M. oertzeni ) / subopaque, punctures comparatively larger and denser (specimen from Mt. Athos); pronotum slightly longer than wide, slenderer (syntype M. oertzeni and holotype ‘var. sporadensis ’) / slightly transverse, shorter and wider (specimen from Mt. Athos); apical sutural angle of elytron rounded (syntype M. oertzeni and holotype ‘var. sporadensis ’) / nearly obtusely angulate (specimen from Mt. Athos). Unfortunately, we only possess images of the type specimens of M. oertzeni and its synonym var. sporadensis in insufficient quality. The concept of M. oertzeni sensu Bucciarelli (1978) requires further confirmation with remains impossible until the missing aedeagus of the syntype M. oertzeni is found or topotypic specimens from Samos become available for study.

Supplementary description. We present photographic images of the Greek specimen from Mount Athos ( MSNM; det. I.Bucciarelli) of M. oertzeni oertzeni sensu Bucciarelli (1978) and the male aedeagus of this species for the first time ( Fig. 22A ). Additionally, we studied the ♂ holotype of M. oertzeni sicula Bucciarelli, 1978 at MSNM: Colla 920 F. Vitale [handwritten, black frame] // Prep. microscp. No. [printed] 526 [handwritten] [label blue] // HOLOTYPUS [printed] Microhoria (Platyhoria) oertzeni sicula n.subsp. [handwritten] Det. Bucciarelli I. [printed] 1977 [handwritten] [label red], and provide an image of the aedeagus of this taxon ( Fig. 22B ).

Ecology. Unknown.

Distribution. Albania, Bulgaria, Greece (mainland, Aegean islands: Samos). The record from North Macedonia in Chandler et al. (2008) which was consequently followed by Telnov (2020a) is erroneous and based on misinterpretation of Bucciarelli’s (1978: 168) ‘ Macedonia, M. Athos’ in Athos Peninsula in a Greek geographic region of Macedonia and not in the country of North Macedonia. The record from Sporades Islands ( Pic 1901b) is based on Pic’s misinterpretation of the geographic position of Samos Island which Pic possibly considered to be a part of the Sporades but which in fact belongs to the eastern Aegean islands. Occurrence of this species in W Turkey is very likely. Subspecies sicula Bucciarelli, 1978 is considered endemic to Sicily.

Chorotype. E-Mediterranean (3.03 EME).
