:I would tend to agree that the sources here don't tell us much about S. dentata. The ZooGram article could be talking about S. gracilipes, although it's also possible that other species in the genus display the same behaviour. Bolin et al. () merely list S. dentata without giving any other details. This source lists a new synonymy, as follows: 
 ::Stenocara crenata (Thunberg, 1787) comb. nov.) 
 :::Erodius crenatus Thunberg, 1787: 41 
 :::Pimelia dentata Fabricius, 1792: 102, 16 syn. nov. 
 :::Pimelia dentata (F.) Herbst, 1799: 112, t. 124, f. 10 
 :::Adesmia dentata (F.) Haag, 1873: 31 
 :::Adesmia dentata (F.) Allard, 1885: 201 
 :::Adesmia dentata (F.) Gebien, 1910. 89 
 :::Stenocara dentata (F.) Gebien, 1937: 660 
 :::Stenocara dentata (F.) Penrith, 1979: 50, 52 
 :Based only on that, I would suggest writing a new article at Stenocara crenata, and redirecting Stenocara dentata there. I don't think there's anything in the current article worth moving across.
