Zaifu Xu, Massimo Olmi, Junhua He

Abstract


Two new species, Dryinus chenae and Dryinus expolitus, are described from Jianfengling National Nature Reserve (Hainan Province, China). Dryinus chenae can be recognized from the related Oriental species D. lini Olmi and D. lianus Xu, Olmi & He by the different OPL/TL ratio (OPL as long as TL in D. chenae, much shorter than TL in D. lini, much longer than TL in D. lianus). Dryinus expolitus can be recognized from the related Oriental species D. choui Olmi by the different sculpture (scutum granulated, with a few small areolae near the posterior margin in D. expolitus; almost completely reticulate rugose, with only the anterior surface of the median region granulated in D. choui) and color (pronotum black in D. expolitus, broadly testaceous in D. choui). Keys are provided for the determinations of the above species with illustrations of female chelae.
