( Figure 7 )

Type specimens. Holotype Ƥ, Panamá, Pr. Nat. Metropolitano, 19 May 1996, leg. F. Oedegaard, on Arrabidaea candicans ( MCCI). Paratypes: 1 Ƥ, idem, 2 Februar 1995, leg. F. Oedegaard on Pithecoctenium crucigerum ( FODC); 1 Ƥ, Panamá, Parque Nat. Metropolitano, Dosel, Castilla elastica , 23.IV.1999, H. Barrios ( MCCI); 1 Ƥ, idem, on Seranja mexicana, leg. F. Oedegaard ( CHAH).

Description of holotype. Length 4.3 mm. Head copper, pronotum dark bronze, elytra black with a bronze reflection anteriorly if strongly lighted and another transversal bronze stripe before middle. Body narrow, elongated. Vertex more than half the width of head, with punctiform sculpture. Eyes barely visible from above, rounded in lateral view. Frons glabrous, with copper reflections. Clypeus flat, without a transverse carina. Antennae short, serrate from antennomere 5. Pronotum gibbous anteriorly, depressed posteriorly, widest before middle, with lateral margins rounded and widely sinuate before posterior angles, which are acute. Anterior margin advanced in middle, between eyes. Sculpture oblique, superficial, with a spot of white pubescence on anterior angles. Premarginal carinula absent. Marginal carinae subparallel, separate from base. Anterior prosternal lobe rounded and entire. Prosternal plate with lateral margins parallel. Scutellum with two transversal carinae: first in anterior margin and second after middle. Elytra with apices rounded and microdenticulate. Disc with rounded spot of white pubescence in humeral callus and at ¾ of length. Another spot, more lengthened, rests before middle, along suture, on stripe of bronze color. Other brief thin and scattered brilliant spots of pubescence are found at apical fifth. Spot of white pruinose pubescence at base of first lateroterga. Ventral surface black, with spot of white pubescence covering integuments at sides of second ventral sterna and at metecoxa. Legs bronze, claws bifid. Metatarsus brief, shorter than metatibia, with first article as long as sum of following two (1=2+3).

Description of paratypes. Both specimens are 4.1 mm in length. In these specimens scattered pubescence at apex is not observable and median spot is divided in two, resembling configuration of 4 (2+2) closed spots.

Etymology. “ Grandinatus ” meaning hailed, for round pubescent spots.

Comments. The description of this species is published in this work, despite the fact it is not found in CMNG. It is included because the presence of a specimen coming from “ Argentinien, Missiones, Puerto Ignazu, 3–18.XII.1990, Foerster leg.” in CMNG that is very similar to these specimens from Panamá. The South American specimen (Ƥ) has not been added to paratypes for being larger and having a more elongated body, waiting further material confirming the identity.
