Redescription. Male: Length 12–17 mm. Form moderate sized, elongate, tapering posteriorly; integument black, abdomen dark reddish brown, metasternum black, occasionally partly dark reddish, scutellum black, elytra black to dark reddish brown, each elytron with two glabrous, elevated,yellowish vittae, and a narrower, elevated, impunctate costa between yellow vittae. Head small; vertex densely, confluently punctate with glabrous area in middle between eyes; front finely, densely punctate; postclypeus finely, contiguously punctate with a median opaque, impunctate area on upper half; genae nitid, sparsely irregularly punctate to impunctate, lower half triangular, finely, closely punctate beneath; pubescence short, dark, erect around base of antennal insertion and postclypeus; labrum finely punctate with longer, golden, suberect setae; antennae exceeding elytral apices by three to four antennomeres; scape conical densely, deeply, contiguously punctate with very short, depressed setae; antennomeres II–V finely, densely punctate, densely clothed with short, dark, depressed setae, remaining antennomeres minutely, densely punctate, densely covered with minute, appressed pubescence and few longer, depressed setae on apices; antennomeres IV–VI vaguely carinate on outside, V–X carinate on inside; antennomere III longer than I; IV subequal to III; V longer than IV; VI, VII, VIII, IX and X subequal to V; XI longest, apical three-fifth vaguely appendiculate. Pronotum wider than long (L/W: 0.8), sides broadly angulate; disc with basal two-thirds impressed in middle, sides above lateral angles arcuately impressed, surface cribriform or alveolate punctate with yellowish seta arising from each puncture; apex with margin collared, narrowly constricted behind; base impressed at sides; proepisternal area rugulose, coarsely, densely punctate; prosternum shallowly impressed, apical half transversely plicate or striate-punctate, basal half on each side above coxae with delimited, finely punctate, transverse, subrectangular area with erect, yellowish setae; mesosternum finely, densely punctate, pubescence short, erect, integument between mesepisterna and mesocoxae glabrate; metasternum sparsely punctate and nitid in middle, sides discretely, shallowly punctate, pubescence depressed and suberect; metepisterna densely clothed with appressed, golden pubescence. Scutellum black, very sparsely punctate to impunctate. Elytra 2.4 times as long as broad; each elytron with raised subsutural yellow vitta not attaining apex, raised submarginal yellow vitta, and dark, glabrous, narrower costa in between; punctures on sutural intervals fine, rather sparse near base, denser and contiguous apically, punctures between costae coarser, deeper than sutural intervals; pubescence minute, dark, suberect. Legs slender, femora slightly clavate, coarsely, densely punctate, dorsum sparsely clothed with short, depressed setae, inner surface clothed with suberect golden setae, meso- and metafemora arcuate near base, metafemora falling far short of elytral apices; tibiae coarsely, deeply, contiguously punctate clothed with short, depressed setae; protibiae with inner surface densely clothed with short depressed, golden pubescence. Abdomen nitid, sparsely punctate in middle, pubescence golden, sparse, short, depressed intermixed with few, longer, suberect setae, sides more densely punctate, more densely clothed with short, appressed setae; apex of last sternite truncate, and vaguely emarginate at middle.

Female: Length 13–18 mm. Form slightly more robust than male, parallel-sided, abdomen usually all black. Prosternum with basal half densely, coarsely, contiguously punctate, and lacking the delimited, finely punctate area before coxae; proepisternal area coarsely, shallowly punctate. Antennae shorter, attaining apices to an antennomere longer than elytra. Abdomen with apex of last sternite broadly truncate.

Discussion. According to Bates (1892: 179), this species is similar in appearance to Lophalia quadrivittata (Bates) . Each side of elytra is flavo-bicostate but differs by the subopaque, densely, sub-rugosely punctate thorax. The body is black except for the two elevated yellowish vittae on each elytron. Head and base of antennae are densely, confluently punctate. Thorax is wider with sides broadly rounded in middle and posterior of the disc is foveate (i.e., pitted with numerous, regular depression or pit) and depressed. The yellow vittae on both sides of elytra almost reach the apices. The subsutural vittae near base is not as dilated (i.e., as in L. quadrivittata ). The interspaces of vittae are densely punctate with a sub-elevated impunctate line in the middle. The apices are obtusely truncate with external angles without spine. The sternum is moderately, densely punctate with gray setae arising from each puncture. Length is 14–16 mm for both sexes. Habitat reported by Bates is Mexico, Venta de Pelegrino, Dos Arroyos (1000 ft) and Tierra Colorado (2000 ft), all from Guerrero.

Lophaliamorpha cribricollis new combination can be distinguished from L. luteicollis (Bates) by the dark elytra with a pair of raised, glabrous, yellowish vittae on each side. The glabrate, alveolate punctate pronotum that is depressed will differentiate this species from the other Sphaenothecus -like trachyderines with the paired yellow costae on each elytron. The front is declivous in middle and antennal tubercles divergent on each side of mid-cranial sulcus ( Fig. 135 ); however, the lateral profile appears subvertical due the perpendicular frontogenal ridge and antennal tubercle ( Fig. 134 ).
