Abstract:The genus Lanka Maulik includes 17 species and is a typical Oriental distribution pattern,which distributed in Yunnan,Taiwan of China;Japan,Vietnam,Thailand,Laos,Sri Lanka and India.This genus is also a sever pest of Piper,Piperacea in India.In present paper,two new species of this genus are described here,Lanka puncticolla Wang et Ge,sp.nov.,from Xishuangbanna,Yunnan;Lanka regularia Wang et Ge,sp.nov.,from Mêdog,Xizang.Until now,19 species of genus Lanka are recorded and five of them distribute in China.Also the catalogue,distribution and host-plants of the known species,key to the species,illustrations of male genitalia,habitus and important structures of some species are provide here.The type specimens are deposited in Institute of Zoology,Chinese Academy of Sciences,Beijing,China.Lanka puncticolla Wang et Ge,sp.nov.(Fig.1) Body ovid,dorsum chestnut brown;vertex,antennae,underside of body,fore-and mid-leg,tibiae and tarsi of hind-leg yellowish brown;apex four segments of antennae infuscate,hind femur dark brown.Vertex convex,smooth and impunctate,with deep longitudinal furrow on lateral side,becoming broader behind eyes;frontal tubercles almost rounded;with carina between anternnae;frontal clypeus convex,anterior with triangulated chamfer;antennae filiform,exceeding to mid part of elytra;antennomere 1 robust,two times longer than antennomere 2,3 slightly longer than 2,subequal to 4,antennomeres 5-11 subequal in length,longer than antennomere 3,two times longer than wide.Pronotum broad quadrate,two times broader than long;central disc very convex,lateral sides arched,lateral bead slightly upfold;with tricobothia closed to anterior angles,posterior angles flat,base curved posteriorly;disc with dense and fine punctures,shagreened among punctures.Scutellum triangular,smooth and impunctate.Elytra with humera calli present and convex;disc with regular striae,scute striole confused.Body length 3 mm.Holotype ♀,China,Yunnan,Xishuangbanna,Nabanhe National Natural Reserve,Anmaxinzhai(22.19°N,100.64°E;alt.772 m) ,16 Apr.2009,leg.MENG Ling-Hui.The new species is close to Lanka laevigata(Chen et Wang) ,but can be distinguished by the punctures of pronotum and elytra;the new species with dense and fine punctures,interspace of elytra wide and flat.But the latter with very fine and unclear punctures,interspace of elytra slightly convex.Etymology.From Latin,punctatus and collaris,means pronotum with clear punctures.Lanka regularia Wang et Ge,sp.nov.(Figs 2-5) Body elongate ovoid,dorsum convex.Body black,central of vertex,antennae,fore-and mid-legs,tarsi of hind-legs reddish brown;underside of body and tibiae of hind-legs black.Vertex convex,antero-lateral part with one big puncture on each side;smooth and impunctate;frontal tubercles elongate-ovoid,almost absent;with furrow closed to posterior of compound eyes,with one big puncture near furrow on each side(Fig.3) .Antennae exceeding to middle of elytra,antennomere 1 robust,2 short,half length of antennomere 2,antennomere 3 1.5 times as long as 2,slightly shorter than 4,antennomeres 5-11 robust,longer than 4.Pronotum broad quadrate,2 times broader than long,central disc convex,lateral sides slightly arched;behind anterior angles with tricobothia;middle of posterior margin anched before scutellum,with one longitudinal depression closed to lateral side;disc with dense and fine punctures,shagreened among punctures.Scutellum half rounded,surface granulate.Elytra with humeral calli convex,punctures of elytra slightly coarser than pronotum,with regular striae,interstice flat,impunctate.First segment of male tarsi broad,pear-shaped(Fig.4) .First segment of abdomen with one hippocrepiform carina antero-medially(Fig.5) .Body length 3 mm.The new species is close to L.nigra(Chj) from Taiwan,but can be distinguished by the following characters:elytra striae regular,scute striole regular.Holotype ♂,China,Xizang,Mêdog(29.2°N,95.3°E;alt.1 100 m) ,21 Jan.1982,leg.HAN Yin-Heng.Etymology.From Latin,regularis,means elytral striae regular.
