description: Gen. Euochin gen. n. - Prószyński, 2018   
Figures 19-20  
 Type species Euophrys atrata Song & Chai, 1992.   
 Documentation studied: original diagnostic photos and drawing (Figs 19 & 20).   
 Etymology: name coined of parts of words Euo [-phrys] and Chin [-a] related to the genus these species were originally placed in, and the country of their occurrence.   
 Remarks. Excellent color macrophotographs and drawings, provided by the original authors (Figs 19-20), perfectly illustrate features of species transferred here to the newly delimited genus Euochin, as well as their differences with rich diversity of all recognizable species of Euophrys (Figs 1-18) and type species of related genera. Original descriptions of these China living species provides additional help to taxonomist able to read Chinese descriptions.   
 Diagnosis. Main diagnostic character of this genus are oval shape of spermathecae, elongate along their longitudinal axes, and shape and position of their short and straight ducts, arising antero-medially from spermathecae (Figs 19C, G), their features reflects on superficial appearance of their epigyne. Palps confront to genera type of these parts in EUOPHRYINES, with coil of embolus somewhat wider than in Euophrys and their center somewhat deeper. There is a dense layer of longer white setae in proximal half of dorsal surface of cymbium and distal edge of palpal tibia (Figs 19B, F, 20 A-C). General appearance of body - with average proportions and cryptic coloration does not display any particular diagnostic characters (Figs 19A, E), frontal view of males is not documented. Placement of E. poloi in this genus requires more consideration.   
 Composition. Type species: Euochin atrata (Song & Chai, 1992) comb. n. (Figs 19 A-D, 20A, D). Other species: Euochin albopalpalis (Bao & Peng, 2002) comb. n. (Figs 19C), E. bulbus (Bao & Peng, 2002) comb. n., (Figs 19 E-H, 20B, E), E. poloi (Żabka, 1985) comb. n. (Figs 20F- I).   
 Species pending placement confirmation: Euophrys longyangensis Lei & Peng, 2012: 2, f. 1a-b, 5a-e and E. robusta Lei & Peng, 2012: 4, f. 2, 6a-c, both described from China in Oriental Insects.
