37. Ademula distincta View in CoL , new species ( fig. 8 View FIGURE 8 , a, b).
Head and pronotum above with only short pubescence, under surface of head, front coxae and femora and first antenna! segment with,long, erect hairs.
Head as long as wide, antenniferous tubercles projecting prominently above bases of juga. Eyes large, half again as broad as interocular space, hind lobe of head rounded behind, feebly longitudinally impressed along middle. Antennae over half again as long as body, 209: 130, proportion of segments one to four as 83: 83: 30: 13; slender throughout. Proportion of rostral segments about 13: 10: 13; middle segment only moderately swollen at middle, not exceeding greatest thickness of first segment.
Pronotum strongly constricted in front of middle, the front lobe about two thirds as long as hind lobe, rounded and smooth laterally, slightly granular at middle and impressed just behind middle. Hind lobe more coarsely granular, moderately convex with a broad longitudinal impression along middle nearly as long as broad across humeri, 24:26; laterally only faintly carinate. Anterior disk pubescent, especially laterally, posterior disk without pubescence and without spines or processes. Hind margin shallowly but distinctly angulately emarginate.
Mesonotum three fourths as long as broad, with an erect spine at middle, the spine half as long as mesonotum. Metanotum scarcely spined, with a very short subacute tubercle at apex. First abdominal tergite with a prominent, erect spine about the size of mesonotal spine.
Hemelytra very long and slender, six times as long as greatest width, the venation as figured for Ademula reticulata McAtee and Malloch (Philippine Jour. Sci. 30:pl. 3, fig. 23 View FIGURE 23 , 1926).
Legs relatively long and slender, the hind femora exceeding tip of abdomen by about one seventh their total length. Middle and hind femora not conspicuously enlarged apically. Front femora with four well-developed spines on basal half. Front tarsi apparently two segmented.
Abdomen more than twice as broad subapically as subbasally. Male with a short, rounded tubercle on either side of hind margin of pregenital segment. Genital capsule biemarginate apically as seen from behind with a broad, apically rounded process between, this process twice as long as broad at apex. Claspers elongate, about as long as posterior process, rounded apically. Female with a small, rounded process on either side of subapical tergite.
Color pale, testaceous, with brown head, brownish base and apex of rostrum, and irregularly and faintly infuscated first antenna! segment except for pale apex. Subbasal, median, and subapical brown annulations on front femora and tibiae, at ieast subapical annulations on middle and hind femora and various brown hemelytral markings as follows: main veins at middle of basal third, broad suffusion slightly in front of middle of hemelytron rather broadly broken by large reticulations at middle, and along inner margin of apical half of discal cell and across this vein to middle of inner apical cell.
Size: length 6.3 mm.
Holotype male, allotype female, and seven paratypes, Mt. Tenjo , May 3, Usinger ; two paratypes, Mt. Chachao , May 16, Usinger ; three paratypes, Dededo , May 11, on Ochrosia and Cycas, Usinger ; one specimen, Upi Trail, May 5, Usinger.
Very close to Ademula reticulata McAtee and Malloch , from Singapore, Borneo, and the Philippines, despite the apparently two-segmented front tarsi and the absence of uniformly long hairs on head and anterior lobe of pronotum. The hemelytra are only about four times as long as greatest width in that species, and the fuscous markings of the hemelytra are more extensive. From the present material I am not able to judge whether this is an unwarranted extension of the generic concept of Ademula or not. I collected a new species which is very close to this at Los Banos, Luzon, but this species has much longer hairs on the legs and on the first antennal segment, the mesonotal spine is longer, the black subapical annulations are strikingly narrow on the first antennal segment and on the middle and hind femora, and the posterior process of the male genital capsule is narrower at base and broader and rounded apically.
Both of these species will run directly to Empicoris in McAtee and Malloch's key but they obviously have nothing to do with this genus, the venation, in particular, referring them directly to Ademula . Kirkaldy's Fijian calamine is related to distincta but has shorter hairs on the first antennal segment, has a smoother pronotum with long, fine hairs anteriorly and laterally, and is shorter and broader with differently colored hemelytra.
