Marmessoidea hainanensis yinggelingensis Ho subsp. nov. E/T

Type. Holotype: ♂, Yinggeling Nature Reserve , Baisha, Hainan, China, 29.IX.2010, George Ho Wai-Chun (BFU).

Description. Male. Medium-sized. Slender and slim. General colour of body and legs dull green. Head smooth and rounded. Compound eyes big and rounded, about 1.5 times length of genae. Occipital furrows and swellings indistinct. Antennae blackish brown with yellowish brown rings, filiform, longer than body length; scapus about 1.5 times length of pedicellus, shorter than third segment. Pronotum rectangular, longer than wide, as long as head, sparsely covered with indistinct small granules, with transverse and longitudinal sulci crossing before centre, anterior margin weakly curved inwards, posterior margin rounded. Mesonotum elongated, parallel-sided, 4 times length of pronotum, sparsely covered with inconspicuous small granules, mediolongitudinal line distinct. Mesopleurae, mesosternum, metapleurae and metasternum lacking granulation. Abdomen smooth. Second to sixth terga roughly equal in length. Seventh tergum as long as combined length of eighth and ninth terga. Eighth tergum as long as ninth tergum. Anal segment shorter than ninth tergum, with a small notch and sparse short bristles on posterior margin. Poculum cup-shaped, posterior margin rounded, reaching middle area of anal segment. Cerci cylindrical, curved inwards, apices rounded. Legs slender and long. Unarmed, sparsely covered with short bristles, bristles on ventral carinae shorter than bristles on dorsal carinae.
