Table 1. Summary of morphological features for differentiating Chitoniscus Stål, 1875 sensu stricto from Trolicaphyllium gen. nov. as these two have been mistakenly associated for more than a century. Listed morphologically from the anterior to posterior.
FemaleTrolicaphyllium gen. nov.Chitoniscus Stål, 1875 sensu strictoAntennaeAntennomeres III, VIII, and IX widened, broader than the antennomeres between; Fig. 4A.Antennomeres III, VIII, and IX not widened, with similar diameter as the antennomeres between; Fig. 4BAntennae: third antennomereBroadened, sr not shifted anteriorly, sf meeting sr in anterior third; Fig. 5A. Sf long, ≥ 35 teeth; Fig. 5ANot broadened, sr shifted anteriorly, sf meets sr at half of its length; Fig. 5B. Sf short, ≤ 30 teeth; Fig. 5BAntennae: third antennomere (sf teeth)Teeth with a smooth apex; Fig. 5CTeeth with a weakly bilobed apex; Fig. 5DAntennae: first antennomereDorsal surface without notable expansion, flush with anterior of the segment; Fig. 6A, CDorsal surface with expansion projecting anteriorly alongside the 2nd antennomere, projecting beyond the anterior end of the segment; Fig. 6B, DProtibial interior lobeAlways spanning the full length of the protibial shaftEither absent or even in the most well-developed forms only on the proximal half, never fully spanningPrescutum anterior rim sagittal spineSpine and rim distinct, but not large; Fig. 7A. Rim and spine situated on the anterior margin, not strongly protruding posteriorly; Fig. 8ASpine and rim prominent; Fig. 7B. Rim strongly protruding and angled posteriorly; Fig. 8BVentral coxae colorGreen, similar shade as the remainder of the insect; Fig. 9ASky blue in color; Fig. 9BTegmina: R and MR runs parallel with M until the split of Rs, at which point Rs bends away distinctly; Fig. 10AR diverges steadily from M for the full length, therefore the split of the Rs is not a significant bend; Fig. 10BTegmina: R-M crossveinR-M crossvein does not fade, but fully reaches to and connects with M; Fig. 10AR-M crossvein thins and fades before reaching M; Fig. 10BTerminal abdominal segmentBroad; almost two times as wide as long; Fig. 11ANarrow; approximately as long as the greatest width; Fig. 11BCerci textureWeakly granular/smooth; Fig. 11AHeavily granular; rough textured; Fig. 11BTarsusEuplantula 2 and 3 with ridgelike expansion along the entire tarsomere; Fig. 12BEuplantula 2 and 3 without ridgelike expansion; Fig. 12BMaleOcelliWell developed; Fig. 13AAbsent; Fig. 13C, DProtibial interior lobeAlways spanning the full length of the protibial shaftTypically, absent or in well-developed forms only on the proximal half, rarely fully spanning and if so only as a thin lobePrescutumAnterior margin more typical of a phylliid with the margin not strongly curved, making the prescutum appear less compacted; Fig. 13A, BAnterior margin angled posteriorly, making the prescutum appear very stout; Fig. 13C, DAlae: R split into R1 and RsSplit is approximately ⅖ of the way through the wing; Fig. 14Split is approximately halfway through the wingAlae: MA and MPMedia anterior (MA) and media posterior (MP) veins fuse with the cubitus (Cu) at different locations along the cubitus and run fused to the wing margin; Fig. 14Media anterior (MA) runs unfused to the wing margin; media posterior (MP) fades without fusing or reaching the wing marginEggsOperculumRaised on the ventral end, not centrally raised, no pit, minimal granulation throughout; Fig. 15CCentrally raised and with a pit in the center; Fig. 15FGeneral chorionic textureSmall spherical surface structures; Fig. 16A, B, also present on the micopylar cap Fig. 16CTuberculate chorionic surface, rough; Fig. 16D, E, pinnate micropylar cap; Fig. 16FMicrostructuresMushroom-like smooth granula; Fig. 17BSmall pinnae arranged in ridges; Fig. 17EFreshly hatched nymphMeso-, metafemoral colorationProminent white patch on the center of the exterior lobe and onto the femoral shaft; Fig. 18AMostly black in color, no prominent white patches; Fig. 18BMesonotumSlender, posterior width similar to length; Fig. 18AStout, posterior width greater than length; Fig. 18BAbdominal colorationAbdomen black with the margins of segment II-IV and VI-IX green; Fig. 18AAbdomen uniformly black, no green margins; Fig. 18BDistributionNew Caledonia; Fig. 21Fiji
