摘 要：
皮蝽科Piesmatidae是半翅目中的一个小科,已知约三十余种,主要分布于全北区,也有少数分布于东洋区和非洲区。本科种类的特征是身体背面具特大的网状刻点,头侧叶发达,通常伸出于头中叶的前方;眼及触角之间呈刺状突起,有单眼;触角四节,第三节细长,第四节纺锤形,端半部被半直立长毛;喙四节,伸达或超过前足基节。前胸背板具二条,三条或五条纵脊;有前胸侧板窝。附节二节,具爪垫。本科与长蝽科接近,但头、前胸背板及足的构造不同。它和网蝽科种类的外形颇相似,但小盾片外露,前翅

摘 要：
The present paper gives a general discusion of the family and enumerates nine species of Piesmis from China. Among them four species are recorded for the first time from this country and three are described as new to science. The new species may be diagnosed as in the following key.1(8) Pronotum bicarinate, antenniferous tubercles subconical, not branched, (f. 1.2) :2( 3 ) Paranota narrow, about 1/4 of the distance between the 2 carinae and with onerow of areolae which sometimes doubled anteriorly: pronotum narrowed anteriorly,width between anterior angles nearly 1.5 X the width between lateral angles (f. 1).....................................................P. capitata Wolff (n. rec.)3(2) Paranota broad, not less than 1/3 of the distance between the 2 carinae, often with 2-3 rows of areolae; pronotum anteriorly a little broader than posteriorly (f. 2):4(5) Lateral margin of pronotum gently rounded ..........P. chiniana Drake et Maa5( 4 ) Lateral margin of pronotum nearly straight or sinuate at middle:6( 7 ) Juga greatly longer than tyius, with apices curved inward in front of tylus or pointed forward with tips often feebly upturned; pronotum with lateral margin distinctly sinuate at middle; head narrower, about 1.4X of its length; paranoia with 1 row of areolae after middle (f. 2); me tasternusn flat, with posterior margin broadly rounded (f. 3) ..........................................P. macalata (Laporte)7(6) Juga slightly longer than tylus and not curved inward in front of tylus; head wider, about 2.4X its length; lateral margin of pronotum slightly sinuate at middle (f. 4), paranota with 3 rows of areolae for its whole length; metasternum longitudinally sulcate with apex truncate (f. 5). Length 2.4-2.5mm. Yellowish-brown, tylus and antennae brown. Type: ♂; Kwangtung (Xisha Is.)..........................P. xishaena sp. nov.8(1) Pronoturn tricarinate, (f. 6,8.) antenniferous tubercles bifurcate, the upper branch Smaller, (f. 9) :9(12) Pronotum with lateral area somewhat flat, without lateral carinae (f. 6, 8.). Ma-cropterous form common:10(11) Pronotum anteriorly narrower lateral margin straight and posteriorly divergent; head with juga longer than tylps. not attaining apex of 1st antennal segment and curved inward in front of tylus and contact each other; mc'tasternum with apexnarrow, about as wide as the diameter of posterior coxae (f. 7)..................................................................P. guadrata (Fieber) (n. rec.)11(10) Pronotum with apex as wide as base, lateral margins sinuate at middle (f.8); head with juga much longer than tylus, surpassing apex of 1st antennal segment pointed straight forward or slightly curved inward; posterior margin of metasternum broad, about 2X as broad as diameter of posterior coxae (f. 10). Length2.48-2.66 mm. Yellowish brown to greenish brown ........................................................................P. variabile (Fieber) (n. rec.)12 ( 9 ) Surface above propleural cavity distinctly raised so as to form a lateral carina (f. II, 13). Brachypterous form common:13(16) Smaller, body length under 3.0mm; anterior angles of pronotum broadly rounded (f. 12) ; median carinae spotted. Matasternum posteriorly narrowed or pointed. Costal area of hemelytra with 6-8 dark spots: 14(15) Antenniferous tubercles with upper branch smaller, about 1/4 as long as lowerbranch; rostrum not passing apex of fore-coxae; membranes of brachpterous formwith apecies of inner margin angulately projected and overlapped one another (f.II). Length 2.48-2.79 mm. Ochraeeous to grayish brown..............................................................................P. josifovi Pericart (n. rec.)15(14) Antenniferous tubercles with upper branch longer, about 1/2 as long as lower branch(f. 12) rostrum passing apex of fore coxae; membrances of brachypterous formwith inner margin straight and in contact each other forming a straight line.Length 2.17-2.66mm. Yellowish brown to grayish brown. Type: ♂, Peking...................................................................P. longicarina, tp. n
