Kema pamae Vásárhelyi , sp. n.

http://zoobank.org/ 5151127B-D4A8-4964-B210-CE283A52935E (Figs 17–19, 23–24)

Description – f. Macropterous, large, with characteristic pattern of decorative setigerous tubercles or granules along and on the body, arranged in rows or circles, sometimes randomly on surfaces; with almost wing-like fore lobes on pronotum; and with acute, caudally increasingly protruding PE angles of deltgs. Body in general dark brown, with paler colour on glabrous areas and deltgs on posterior segments of abdomen.

Head distinctly longer than wide, on vertex with an M formed by granules. Anterior process of head slightly widening anteriorly, reaching about 1/3 of first antennal joint, Figs 17–22. Kema pamae sp. n. (17–19), K. acutissima Kormilev, 1971 (20–22): 17, 20 = anterior part of body of female; 18, 21 = tip of abdomen, dorsal view; 19, 22 = tip of abdomen,

ventral view clypeus elevated above genae. Antenniferous tubercles reaching about to middle of genae. Postocular spines much surpassing lateral outline of eyes. Rostral groove closed, surrounded by multiple rows of granules. First two antennal joints densely covered by granules. Relative lengths of antennal joints I to IV as 40:19:36:14.

Pronotum about one third as long as wide across anterolateral lobes, with anteriorly protruding collar, somewhat wider across anterior lobes than posterior lobes. Anterolateral lobes widening towards apex. On the fore disc granules forming longitudinal rows on lateral carina and an X-shaped pattern, enclosing a small elevated area medially. Hind disc with elevating, short lateral carinae and transversely scattered granules in median part. Granules particularly coarse along edges of lobes.

Scutellum large, triangular, apex somewhat protracted, slightly longer than wide, with two strong, subparallel longitudinal rows of granules medially, overlapping hind border of pronotum, and with coarse granulation on anterior angles. Margins carinate except at apex. Surface of disc uneven, not rugose, except near apex.

Hemelytra reaching posterior border of tergum VII, with protruding, triangular lobe basolaterally, anterior border concave, posterior border convex. Corium almost reaching hind border of deltg IV, bearing sporadic setigerous granules, dark brown in colour except basally.

Abdomen with acute PE angles of deltgs, increasingly developed from segments II to VII. Glabrous areas irregularly surrounded by granules, which are small and scattered on PE angles. Deltg VIII slightly surpassing segment IX. Spiracle VIII near to tip, visible also from below, in male ventral, not visible from above.

Measurements – holotype f: length of head 2.7 mm, width of head 2.0 mm, length of pronotum 1.8 mm, width of pronotum across fore lobe 5.5 mm, width of pronotal disc 3.8 mm, with of pronotum across hind lobe 5.1 mm, length of scutellum 3.0 mm, width of scutellum 2.8 mm, maximum width of abdomen across segment IV 8.0 mm, total length of body 14.2 mm. Paratypes m: body length 12.0 and 13.0 mm.

Type material – Holotype f: “ INDONESIA Halmahera / Isl., Tobelo Dist. / Kampung Ruko / 11 April , 1981 / AC Messer & PM Taylor ”; deposited in the USNM . Paratypes: “Sidangoli / Batu putih, 100m / 22-23 XI 1999 // N-Moluccas / Halmahera / leg. A. Riedel ” (2 mm, CEHI). The holotype and paratypes were provided with type labels accordingly .

Etymology – This magnificent new species is dedicated to Ms Pam Tooley, earlier serving as a museum educator of the Heard Natural Science Museum and Wildlife Sanctuary in McKinney, Texas, who, together with her husband Dr W. Tooley, helped and hosted the first author generously during his stay, thus finally he could pay short visits to the Hemiptera Collections in New York and Washington.

Discussion – In the key of KORMILEV (1971) the examined individuals run to K. acutissima on the basis of the shape of the pronotum and the body size. K. pamae sp. n. differs, however, by the following characters (character states for K. acutissima are provided in brackets): antennal joint II being flattened laterally and distinctly thicker in dorso-ventral direction (subcylindrical). Anterior process of head slightly widened anteriorly (parallel); anterolateral lobes of pronotum wider and more widening towards apex (less so); surface of disc uneven, but not rugose on most part (distinctly rugose); deltg VIII slightly surpassing segment IX (more strongly surpassing); spiracle VIII placed near to tip, visible also from below in female (visible from above only).

Considering the ratio of the widths of the anterior and posterior lobes of the pronotum and the length and pointed nature of PE angles of deltgs, the female holotype is transitional between K. acutissima and K. lobulata ( Figs 23–26 , 29–30 ). The midlateral row of glabrous areas is about half as wide as the exterolateral one in K. lobulata, (similarly to K. bloetei), they are narrowing posteriorly in K. papuasica, whereas they are similar in width in the other two species. The anterior lateral lobes of pronotum are most widening towards apex in K. pamae sp. n.
