Xenotingis kokodae sp. n. ( Fig 13, 14 )

Material examined: 1F, New Guinea, Papua, Kokoda­Pitoki, 450m, 24. III.1956, J.L. Gressitt, BPBM.

Description: Body shiny, hemelytra hyaline and clear brown, pronotum, head, hind tarsi, and last antennal segment dark brown, body beneath clearer than pronotum but darker than hemelytra. Body length, 3.83; width, 1.77.

Head armed with five long and slender spines, directed forward, frontal and median spines converging; bucculae triseriate, areolae small, closed in front; antennae long and slender, antennal segments measurements: I, 0.17; II, 0.12; III, 1.70; IV, 0.43; rostral sulcus narrow, slightly wider on metasternum, open behind, laminae wide and foliate, areolae quite large; rostrum reaching suture between third and fourth abdominal segment.

Pronotum short, a little gibbose, tricarinate; median carina raised, uniseriate, areolae subquadrate and large; lateral carina raised, a little higher than median carina, uniseriate, areolae subquadrate and large; collar triseriate, areolae small, raised on top as to form a hood; hood inflated, cyst­like, longer than wide, also longer than high, connected with median carina and higher, partly covering head, reaching level of base of antennae, constricted by paranota; paranota wide, strongly developed, raised, as high as wide, covering pronotum, except posterior process, areolae polygonale and large, first two basal rows rectangular, hyaline areolae, other areolae enbrowned, margins meeting posterior, but not meeting on top and anteriorly, and invaginated as to form a hole in the middle of pronotum.

Hemelytra moderately widened in the middle; costal area triseriate, two basal rows of areolae irregularly arranged, sloping upwards, third outer row of larger quadrate areolae, reflexed, the outer margin meeting RM vein, and, on the same plane as the discoidal and sutural areas; subcostal area as wide as basal part of costal area, biseriate, areolae smaller, vertical and perpendicular to discoidal and sutural areas; discoidal area longer than half the length of hemelytra, wide, seven to eight areolae wide at widest part, areolae as large as on subcostal area; sutural area large, five areolae wide at widest part, areolae larger than on discoidal area.

Etymology: The name refers to the location where the specimen was found.

Comments: X. papuana Drake and X. tinae Drake and Ruhoff do not have the same paranota shape. Xenotingis bakeri Drake has a different pronotal hind process and no hemelytral subdivision. Xenotings malkini Drake differs by its triseriate inner part of the costal area and the shape of its paranota. Xenotingis horni Drake differs by its widely open paranota above the pronotum. Xenotingis luzoana Drake differs in having the paranota shorter than long and covering the hind pronotal process. Xenotingis missai Péricart differs by the biseriate costal area, whereas the costal area is triseriate in X. kokodae , the outer row made of large cells, reflexed inward and touching the RM vein. However, the paranota have the same shape with the outer margins in contact only posteriorly and crescent­like above the pronotum, allowing to see from above a part of the pronotum and the median carina.
