Derivation of specific epithet.
The specific epithet, verrucosa , is a feminine Latin adjective referring to the tuberculate elytra.
Proposed English vernacular name.
Verrucose humps-backed beetle.
With the attributes of the genus and tuberculata species group as described above and adults with only dark non-metallic markings on the pronotal disc, pronoum with rounded margins, elytron just posterior to scutellum with a V-shaped pale area encompassing the scutellum and sutural and first interval, venter substantially infuscate, and elytra narrow, not broadly arcuate.
(Figs 9B, 10E). Size: See Appendix 1. Length (SBL) long for genus, ABL = 4.47-5.66 mm, SBL = 3.79-4.90 mm, TW = 2.06-2.85 mm.
Color: See diagnosis, above.
Luster: Without any metallic highlights, shiny and matte.
Microsculpture: Mostly isodiametric and stretched, shallowly impressed, cells somewhat more stretched around elytral tubercles.
Head: Rugae moderately coarse, mostly without patterned arrangement. Eye markedly large, sub-hemispheric, evenly rounded anteriorly, subtly more prolonged posteriorly. Antenna short, barely reaching humerus. Labrum rectangulate, shallowly bilobed, anterior margin slightly emarginate. Neck finely transversely rugose.
Prothorax: Pronotum moderately broad, disc centrally depressed with coarse angulate rugae. Lateral margins broadly explanate and evenly rounded to obtuse hind angle, base medially produced and rounded posteriorly.
Pterothorax: Normal for Agrina , fully winged. Elytron intervals 3 with 8, and interval 5 with 6 prominent discal unisetiferous tubercles, interval 4 with sub-apical pale colored “lens,” other intervals moderately convex, side margin broadly explanate laterally only at middle third. Elytron broad and moderately short, much narrower in width than that of the pronotum at the broadest part, apex truncate, slightly rounded with distal corner broadly and obtusely rounded, disc not significantly convex, basal third slightly depressed. All interneurs well-impressed.
Legs: Femur dorso-ventrally moderately depressed, tibia coequal in length, more depressed; tarsus less than half the length of the tibia, fourth tarsomere markedly bilobed and with tarsal pad of setae.
Abdomen: Sparsely setiferous; normal ambulatory setae on sterna 3-5; female with two pairs of ambulatory setae on sternum 6, medial pair of setae less than the length of lateral pair; males with only the lateral pair of longer setae.
Male genitalia: (Fig. 10E). With ostium of 1/5 its length, catopic, apex short, rounded; endophallus with flagellum, flagellum not barbed. Parameres asymmetric, right very small, left larger.
Female genitalia: Not investigated, likely similar to that of H. lucida (Fig. 8).
These beetles are macropterous and capable of flight. They are moderately swift and agile runners. Adults of this species are attracted to C.D.C. light traps.
Way of life.
Adults are common in the lowlands (6 to 829 m.a.s.l.) and appear to be generalists in rainforest biotopes such as terra firme and secondary rain/pine forest. In these forests, they are commonly found in big trees with vines and epiphytes, in suspended dry Cecropia leaves, and in dry Astrocaryum chambira Burret palm frond skirts. Individuals can be found in January-November, in both the rainy and dry seasons. Member of this species have been recorded from the canopy of the following tree species using insecticidal fogging techniques: Chrysophyllum argenteum cf.; Sterculia colombiana cf.; Parkia multijuga cf.; Naucleopsis herrerensis cf.; Matisia malacocalyx cf.; Pseudolmedia laevigata ; Browneopsis ucayalina ; Simira cordifolia /rubescens cf.; Brownea grandiceps cf.; Talisia bitter; Virola decorticans cf.; Pouteria cuspidata ssp. robusta cf.; Diospyros sericea ; Guarea silvatica ; Lacistema nena cf.; Guatteria glaberrima cf.; Luehea seemanni ; Cordia alliodora .

(Fig. 11). This species is currently known from the restricted type locality (see above) in Colombia, and from Brazil - Amazonas; Ecuador, French Guiana, Panamá, Perú, Suriname, Trinidad and Tobago, and Venezuela.
Reichardt (1973) reported additional localities under his treatment for this name; however, he also synonymized H. verrucosa with H. tuberculata in Reichardt (1971). Since we do not accept his action and regard them both as good species, we cannot use his locality records without access to the specimens he saw in order for us to correct his identifications.
