Paragrilus laevicollis Waterhouse

( Figs. 10 )

Paragrilus laevicollis Waterhouse, 1889: 127 .

Diagnosis: Agriliform, flattened above, head with bluish reflections dorsally, pronotum black with bluish reflections on anterior half, dark blue on posterior half, elytra dark blue, black beneath; 5.9 mm long. Head with front somewhat convex, narrowly impressed along midline with deeper linear depression above middle; epistoma narrowly depressed between antennal insertions, ventral margin distinctly produced, quadrate, angulate­emarginate, angles broadly acute; surface finely punctate, indistinctly shagreened. Pronotum weakly convex, prehumeral callosity almost obsolete but indicated by weak lateral depression, depression stronger anteriorly; prehumeral callosity produced outward and anteriorly to form narrow ridge above and roughly parallel to marginal carina; anterior angles narrowly rounded­angulate; disc strongly transversely depressed along midline at basal margin before scutellum and more narrowly so at base of lateral depressions, surface indistinctly shagreened on basal half, becoming minutely transversely striolate and more strongly shining on anterior half. Elytra with posthumeral carina extending not quite as far beyond hind coxae as before, surface indistinctly shagreened, with fifth interval faintly raised, forming costa; apices broad, rounded­subquadrate. Posterior angles of hind coxae rounded­subquadrate.

Type: Two specimens mounted on one card with the label “Bugaba, Panamá: Champion” (BMNH). The left­hand specimen is mounted with the dorsal side up and is designated the Lectotype. Both specimens appear to be females.

Host: Unknown.

Discussion: This species, as angulaticollis , has not been recollected since Champion’s original collections.
