Cysteochila copal   nov.sp. (Figs 4,5)

M a t e r i a l e x a m i n e d: Holotype female, embedded in a block of epoxyd resin, 13x13x 6mm, head and prosternum ventrally obscured by impurities of the Copal, the structural details are not recognizable.

D e s c r i p t i o n: Body length, 4.05 mm; width, 1.55 mm, coloration uniformly brownish, the posterior part of hemelytra darker; base and third quarter of costal area yellowish.

H e a d: Short, armed with five small and slender tubercles, an occipital pair, a frontal pair and a median tubercle; bucculae short, not extending in front of clypeus, contiguous in front; rostrum reaching metasternum; antennae long and slender, length of antennal segments I 0.18 mm; II 0.15 mm; III 0.95 mm; IV 0.45 mm.

P r o n o t u m Length, 2.0 mm; width, 1.5 mm; swollen, punctate, with areolae on collar and on posterior process; disk tricarinate, carinae raised and uniseriate, the areolae subquadrate; lateral carinae diverging posteriorly; collar inflated forming a small hood; paranota wide with 12 areolae at its widest part, reflexed onto the pronotum, concealing the lateral carinae but not meeting on the top, composed by two inflated parts, one lateral, the other one above the level of lateral carinae; rostral sulcus not visible.

H e m e l y t r a: Length, 2.8 mm; width 1.55 mm, divided into the usual areas; costal area narrow, of the same width along its whole length, with two rows of small round areolae at anterior fourth, uniseriate and with larger areolae opposite to apex of discoidal area; subcostal area biseriate, uniseriate posteriorly to apex of discoidal area; discoidal area longer than half the length of the hemelytra, six areolae wide at its widest part, these areolae slightly larger than on subcostal and costal area; sutural area large, nine areolae wide at its widest part, areola larger than on other areas.

E t y m o l o g y Refers to the Madagascan Copal resin, where this new species was trapped.

D i s c u s s i o n: This species is similar to C. impressa   , but the costal area is mostly uniseriate while it is completely biseriate in C. impressa   . It resembles also C. expleta DRAKE & MAA 1954   , described from India by the uniseriate costal area, but C. expleta   has a biseriate part at the middle of the costal area. In addition, it has paranota not concavely impressed and ridge-like in the middle like C. impressa   .
