Formmoderate sized, sides subparallel. Headwith front short, declivous in middle, mid-cranial sulcus (or median line) deeply canaliculate or well defined, extending from postclypeus towards vertex past antennal tubercles, each side above postclypeus below antennal insertion with a deep pit, frontoclypeal sulcus transversely excavated between pits; genae very short, anterior margins of lower eye lobes almost contiguous with base of mandibles; palpi short, subequal, last segments not expanded, outer edges of maxillary palpi impressed, apices truncate; mandibles with sides strongly angulated near base then arcuate towards apices, outer edges vaguely impressed and striate-punctate; apices simple, narrowly rounded or truncate; eyes moderately large, finely faceted, upper lobes small, well separated, lower lobes large; antennal tubercles divergent, moderately elevated above vertex, apices angulate; integument between tubercles deeply impressed; antennae elongate, slender, 11-segmented, 11 thantennomere vaguely to non-appendiculate. Pronotumhexagonal, slightly broader than long, narrower than base of elytra at humeri, sides obtusely tuberculate to angulate; disc arcuately impressed above lateral tubercles and basal two-thirds distinctly flattened or impressed in middle; prosternum with intercoxal process level with coxae, narrower than coxal cavity, occasionally impressed medially, apex vertically concave, coxal cavities wide open behind; mesosternum with intercoxal process prominent, protuberant above coxae, vertical or abruptly declivous and excavated anteriorly; posterior-lateral margins vaguely overlapping coxae. Scutellumtriangular, glabrous, apex attenuating to a narrow point. Elytraeach with three, distinct, longitudinal, glabrous costae; apices obliquely truncate, serrate with sutural angles minutely dentate, exterior angles obtusely angulate to rounded or minutely dentate. Legsmoderately short; metafemora falling short of elytral apices in both sexes; metatarsomere I subequal to or slightly longer than tarsomeres II and III combined. Abdomennormally segmented.   Discussion.  LophaliamorphaEya  new genusis characterized as follows: (1) head with front short, declivous in middle ( Fig. 121, 135); (2) mid-cranial sulcus (median line) deeply canaliculate or well defined, extending from postclypeus to vertex past the antennal tubercles ( Fig. 119); (5) mandibles with sides strongly angulated near base ( Fig. 121, 135); (3) genae narrow, lower eye lobes almost contiguous with mandibles ( Fig. 120, 134); (5) antennal tubercles moderately elevated, divergent, and the integument between tubercles deeply impressed forming a V-shaped valley sloping down to mid-cranial sulcus ( Fig. 121, 135); (6) pronotum hexagonal with sides impressed above lateral tubercles ( Fig. 122, 136) and basal two-thirds distinctly flattened or impressed in middle ( Fig. 123, 137); (7) mesosternal intercoxal process that is protuberant above coxae, vertical or abruptly declivous anteriorly ( Fig. 123, 137); (8) each elytron with three, distinct, longitudinal, glabrous costae ( Fig. 124, 138) with apex truncate to obliquely truncate with exterior angle obtusely angulate ( Fig. 126, 138), minutely dentate ( Fig. 125) or rounded; (8) scutellum triangular with apex attenuating to a narrow point; and (10) metatarsomere I subequal to or slightly longer than tarsomeres II and III combined ( Fig. 127).   Lophaliamorphacan be separated from  LophaliaCaseyby the three, distinct, longitudinal, glabrous costae on each elytron, hexagonal pronotum that is cribriform or alveolate punctate with basal two-thirds distinctly flattened or impressed in middle, and obliquely truncate elytral apices with exterior angles usually angulate and unarmed. The front is declivous in middle and the mid-cranial sulcus is deeply canaliculate from the frontoclypeal sulcus on to vertex. The mandibles are strongly angulated at sides, and genae narrow with anterior margins of lower eyes almost contiguous with the base of mandibles. The antennal tubercles are moderately elevated and divergent with the integument between tubercles deeply impressed.  Lophaliacan be differentiated from  Lophaliamorphaby the subparallel form, dark polished integument, broadly rounded sides of pronotum, and strongly dentate exterior angle of elytral apices. The front of  Lophaliais convex and subvertical with integument between antennal tubercles is not or barely impressed.  Lophaliahas mandibles that are arcuate at sides, and the mid-cranial sulcus is shallow or vague. The metatarsomeres are more elongate in  Lophaliamorpha( Fig. 127) compared to  Lophalia(Fig. 128).  Lophaliamorphacan be differentiated from  Zalophiaby the elongate and slender basal antennomeres ( Fig. 68) and cribriform or alveolate punctate pronotum that are not obscured by pubescence.  Zalophiahas short and stout basal antennomeres ( Fig. 65) and pronotum that are densely hirsute.   Etymology.The etymology of the name  Lophaliamorpharefers to the shape or appearance that resembles  Lophalia. The suffix “ -morpha” is Latin from “- morphus” or “shaped” from Ancient Greek μορφή ( morphḗ, “shape, appearance”).  Lophaliamorphais a genus-group name with Latinized feminine ending.
