Abstract
The paper presents comparison of main diagnostic characters of all recognizable species of genera Euophrys C.L. Koch, 1834, Pseudeuophrys Dahl, 1912 and Talavera Peckham & Peckham, 1909, also delimiting new genus Euochin from China. All that purports to illustrate the current state of classification suggests progress and improvements. Discussed postulates include adding color macrophotograps of live specimens to the routine tools of research, and routine use of precisely documented palps and internal structures of epigyne. Implementation of the above will require change of research protocol of all Salticidae, the conclusions drawn are applicable to studies of other families of spiders. New taxa described. Gen. Euochin gen. n. Subgroup of genera EUOPHRYEAE new. Nomenclatorical corrections documentedEuophrys monadnock: Edwards, 1980: 12 (S, in part). = Euophrys nearctica Kaston, 1938c (removal from synonymy, documented - Figs 12B-C with E, as well as relevant facsimiles Figs 32-33).Icius hamatus (C. L. Koch, 1846) (one of synonyms reinstated, female only) = Euophrys altera (Simon, 1868). Euophrys talassica Logunov, 1997 = Pseudeuophrys talassica (Logunov, 1997) - comb. n., Euophrys vittata Caporiacco, 1935 - reinstated from "nomen dubium" to "pending revision" status. Talavera petrensis (C. L. Koch, 1837) = Euophrys petrensis C. L. Koch, 1837 (reinstated original combination). Overdue nomenclatorical corrections: Ballognatha typica Caporiacco, 1935 - nomen dubium, Ballognatha Caporiacco, 1935 - nomen dubium, Ballognathine Caporiacco, 1935 - nomen dubium.
Highlights
This paper purports to survey diagnostic characters of 55 species of Euophrys C.L
The only vividly colored parts of their bodies are faces of males, together with palps and frontal surfaces of legs, visible from the perspective of encountered spiders: mates and competitors. These colors are well visible on live specimens, but dull and unnoticeable when preserved in alcohol
The digestion of information concentrates on diagnostic characters found previously to be the most representative in a survey of over 4800 recognizable species of Salticidae, complemented with macro photographs of live specimens accessible nowadays
Summary
This paper purports to survey diagnostic characters of 55 species of Euophrys C.L. Koch, 1834, 9 species of Pseudeuophrys Dahl, 1912, 14 species of Talavera Peckham & Peckham, 1909 and delimits new genus Euochin gen. n. from China, containing 4 species. The only vividly colored parts of their bodies are faces of males, together with palps and frontal surfaces of legs, visible from the perspective of encountered spiders: mates and competitors These colors are well visible on live specimens, but dull and unnoticeable when preserved in alcohol. Euophrys has a number of species living in Africa The knowledge of these spiders is scanty and insufficient, in part due to difficulty in identification, relating to quick loosing of their natural coloration by specimens submerged in alcohol, to similarity of their palps, differing by indistinct characters, to similarity of external epigyne, and to reluctance of arachnologists to use the only distinct difference - internal structures of epigyne (which require making temporary microscopic slides - simple and easy procedure). For the first time handling and storage of large number of photographs will be easy, owing to electronic technology
