Multiple original spellings, living authors and the Code: The case of Malachius raniansis Mawlood, Hammamurad amp; Abdulla, 2017 (Coleoptera: Melyridae).

The present communication is primarily nomenclaturial-classical taxonomy is only touched in a side note on a diagnosis. It uses technical terminology coined by Alain Dubois, who is interested in the study of the concepts and theory of biological nomenclature (i.e. the "objective connection between the real world of populations of organisms and the world of language" (Dubois Ohler 1997)), and who discusses the current 'International Code for Zoological Nomenclature' [hereafter just called 'the Code'] in great detail. The terms are explained where necessary-but see also the glossaries in Dubois et al. (2019) and the works by A. Dubois cited below.

An annotated checklist of the Iranian Dasytidae and Rhadalidae (Coleoptera: Cleroidea).

We herein provide an annotated checklist for the Iranian Dasytidae and Rhadalidae (Coleoptera: Cleroidea). A total of 54 species and three subspecies of Dasytidae in 16 genera, four tribes and three subfamilies, and 11 species of Rhadalidae in five genera and three subfamilies are reported and discussed where necessary. Of these, 27 (sub-) species of Dasytidae (48%) and eight species of Rhadalidae (73%) are currently known only from Iran, and are here considered as endemic species. However, some species occurences are doubtful or need confirmation. One species (Dasytes xanthocnemus Kolenati, 1846) is reported from Iran for the first time. Furthermore, Danacea micans astrabadensis Pic, 1922 is resurrected from synonymy and given subspecific status.

Effect of monitor display on detection of approximal caries lesions in digital radiographs.

OBJECTIVES: The aim was to compare the accuracy of five flat panel monitors for detection of approximal caries lesions. METHODS: Five flat panel monitors, Mermaid Ventura (15 inch, colour flat panel, 1024 x 768, 32 bit, analogue), Olórin VistaLine (19 inch, colour, 1280 x 1024, 32 bit, digital), Samsung SyncMaster 203B (20 inch, colour, 1024 x 768, 32 bit, analogue), Totoku ME251i (21 inch, greyscale, 1400 x 1024, 32 bit, digital) and Eizo FlexScan MX190 (19 inch, colour, 1280 x 1024, 32 bit, digital), were assessed. 160 approximal surfaces of human teeth were examined with a storage phosphor plate system (Digora FMX, Soredex) and assessed by seven observers for the presence of caries lesions. Microscopy of the teeth served as validation for the presence/absence of a lesion. RESULTS: The sensitivities varied between observers (range 7-25%) but the variation between the monitors was not large. The Samsung monitor obtained a significantly higher sensitivity than the Mermaid and Olórin monitors (P<0.02) and a lower specificity than the Eizo and Totoku monitors (P<0.05). There were no significant differences between any other monitors. The percentage of correct scores was highest for the Eizo monitor and significantly higher than for the Mermaid and Olórin monitors (P<0.03). CONCLUSIONS: There was no clear relationship between the diagnostic accuracy and the resolution or price of the monitor. The Eizo monitor was associated with the overall highest percentage of correct scores. The standard analogue flat panel monitor, Samsung, had higher sensitivity and lower specificity than some of the other monitors, but did not differ in overall accuracy for detection of carious lesions.
