Sinispa tayana ( Gressitt, 1939) 

( Fig. 33View FIGURES 32 – 36. 32)

Rhadinosa tayana Gressitt, 1939a: 172  .

Type locality. China, Hainan Prov., Wenchang, Qizhou Islands, approx. 19º52′– 20º00′N, 111º11′– 111º17′E.

Original type series. Described only from the holotype ( LMNH).

Type material examined. Holotype, pinned: ‘ Hainan Is.,S. China. | Put-ka-shan, Taya | Is. (near Hainan Is.) | July 27, 1934 | C. I. Li [w, p, cb] || HOLOTYPE | RHADINOSA  [hw] | TAYANA [hw] | J.L.Gressitt [r, p + hw by Gressitt, cb] || RHADINOSA  | TAYANA | GRESSITT [w, hw by Gressitt, cb] || [vernacular name in Chinese, hw] || Sinispa tayana  [hw] | Gressitt [hw] | det.

Current status. Valid species.

Remarks. Würmli (1975) transferred R. tayana  to Sinispa  and noted that it is questionable whether the taxon is distinct from S. yunnana Uhmann, 1938  , the only other taxon in the genus. Sinispa Uhmann, 1940  is quite distinct by formation of antennae as it has antennomere I with long spine, II unarmed, III with short curved spine, and IV – VI with two small and gradually shorter spines in combination with basally fused tarsal claws it is similar only to Polyconia Weise, 1905  , which differs in having all six basal antennomeres with spines.

Chen et al. (1986) recognized both S. tayana  and S. yunnana  , as valid species and separated them by the length of the spine on antennomere I (reaching antennomere IV in S. yunnana  or only III in S. tayana  ), number of rows of punctures on elytra (nine in the middle of the elytron in S. yunnana  and eight in S. tayana  ), and length of the lateral spines on elytra (almost as long as apical ones in S. yunnana  and slightly longer in S. tayana  ). We did not examine the type of S. yunnana  however, according to the description the nine rows of the punctures are present only in basal 1/4 length and then are merged with other rows thus around midlength there are only eight irregular rows of punctures just like in the holotype of S. tayana  . Other characters are quite likely subject to intraspecific variation and both taxa are possibly synonymous, however, we leave both valid until we have opportunity to examine type of S. yunnana  .
