Cross section shape: circular elliptical unknown Siphuncle position: central marginal unknown Fig. 4 Morphometrics of orthoconic cephalopods from the Besano Formation. Measurements are compared with discrete characters of the shell. Orange circles represent definite and orange crosses likely orthoceratoids, while blue triangles represent definite and blue crosses likely coleoids. Black crosses are indeterminable. A Apical angle, calculated from length and diameters of the specimens.

Scale bars equal 20 mm.

Figure 2 in Character assassination: a personal witness account with a taxonomic note on the genus Laufeia s. lat. (Araneae: Salticidae)
Figure 2. Photographs of live specimens of: A - Laufeia aenea, female, B - Junqattus daiquini, male and female, C - "Laufeia" [NOT!] concava, male [note proportions of carapace, especially high thorax], D - Orcevia cf. keyserlingi, male and female. COMMENT. External appearance does not support congeneric status of the above specimens, note that identifications are not confirmed by genitalic characters of the specimens.
Figure 3 in Character assassination: a personal witness account with a taxonomic note on the genus Laufeia s. lat. (Araneae: Salticidae)
Figure 3. Facsimile of description of the genus Laufeia and synonymy with genera Orcevia and Junxattus. The description is general, with diagnostic characters meaningless, quoted in general terms, like: usually, relatively, long or short, coiled or uncoiled, usually indistinct, show high interspecific variation [actually belonging to different genera! J. P.]. Note (given by authors) informs of what the authors were thinking, but does not give actual documentation. Authors refers generally to molecular arguments without giving precise and verifiable data (reference Zhang, J. X. & Maddison, W. P. (2013)), so readers are expected to believe but cannot verify these data. Actually a few species tested are insufficient for taxonomic generalizations, some based on misclassified species ("Laufeia" concava is not congeneric with L. aenea - compare figs 1 E-F with 1 W-X, above). HOWEVER, outside the present description, the second author commands too good knowledge of Salticidae to be dismissed without checking each case.
Figure 1 in Character assassination: a personal witness account with a taxonomic note on the genus Laufeia s. lat. (Araneae: Salticidae)
Figure 1. Simultaneous observation of diagnostic characters is necessary for assessment of morphological similarities and differences: five different genera lumped by WSC into single genus Laufeia. Palps, ventral view of epigyne and internal structure of epigyne in: A - Laufeia aenea - type specimens by Prószyński, B - Laufeia aenea - type specimens by Zhang, C - Laufeia [?] "squamata" [mismatched] by Logunov, D - Junxattus daiqini - type specimens by Prószyński, E - Laufeia aenea - type specimens by Prószyński, F - Laufeia aenea - type specimens by Zhang, G - Junxattus daiqini by Prószyński, H - Junxattus daiqini by Zhang, I - Orcevia keyserlingi - type specimens by Prószyński, J - Orcevia keyserlingi by Zhang, K - Orcevia kuloni - type specimens by Prószyński, L - Junxattus daiqini by Zhang, M - Orcevia keyserlingi - type specimens by Prószyński, N - Orcevia keyserlingi by Zhang, O - Orcevia kuloni - type specimen by Prószyński, P - Lechia squamata - type specimen by Zabka, Q - Lechia squamata by Logunov, R - Orcevia keyserlingi - type specimens by Prószyński, S - Orcevia keyserlingi by Zhang, T - Orcevia kuloni - type specimen by Prószyński, U - Junxattus daiqini - type specimen by Prószyński, V - Junxattus daiqini by Zhang, W, X - "Laufeia" [NOT!] concava by Zhang, Y - Lechia squamata - type specimen by Zabka, Z - Lechia squamata by Logunov.
Figure 4 in Character assassination: a personal witness account with a taxonomic note on the genus Laufeia s. lat. (Araneae: Salticidae)
Figure 4. How to evade correcting of own error? New trick invented by editors of WSC: Simon erase of the genus Orcevia corrected? Yes. Repetition of the same error by Zhang & Maddison corrected? Yes. But " revalidation" [whatever that means] of the genus Orcevia (of which O. keyserlingi is a type species) could always be demanded (see Figs 1I-K, M-O, R-T above). Reminds case of the genus Emertonius (above). An additional aspect demonstrated at B - clear trespassing of editorial competence (not to forget arrogance): "assigned to Laufeia" which, by the way, is not a synonym of Lechia.
