Here designated. Male. French Guiana, Cayenne, (MNHP).

Derivation of specific epithet.

The species epithet ‘‘ tuberculata ’’ is a Latinized singular feminine adjective, referring to the bumpy attributes of the elytra.

Proposed English vernacular name.

Tuberculate humps-backed beetle.

Diagnosis.

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, elytron just posterior to scutellum with only the suture pale in color, otherwise markedly infuscate.

Description.

(Figs 9A , 10D ). Size: See Appendix 1. Length (SBL) long for genus, ABL = 4.32-5.88 mm, SBL = 3.94-4.85 mm, TW = 2.18-3.12 mm.

Color: See diagnosis, above.

Luster: Without any metallic highlights, shiny.

Microsculpture: Mostly isodiametric and stretched, shallowly impressed, cells somewhat more stretched around elytral tubercles.

Head: Rugae moderately coarse, mostly chaotic. 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 transversely finely rugose.

Prothorax: Pronotum markedly broad, disc centrally moderately depressed with coarse angulate rugae. Lateral margins broadly explanate and evenly rounded then straight to obtuse hind angle, base medially produced and rounded posteriorly.

Pterothorax: Normal for Agrina , fully winged. Elytron intervals 3 with 8(9) and interval 5 with 6(7) prominent discal unisetiferous tubercles, interval 4 and 6 with subapical pale colored “lens,” other intervals moderately convex, side margin broadly explanate laterally only at middle third. Elytron broad and moderately short, moderately 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 outer pair of longer setae.

Male genitalia: Phallus (Fig. 10D ) robust with ostium of 1/6 its length, catopic, apex very short, broadly rounded in dorsal and lateral aspects; endophallus with flagellum (obvious in illustration), flagellum not barbed. Parameres asymmetric, right very small, left larger.

Female genitalia: Not investigated, likely similar to that of H. lucida (Fig. 8 ).

Dispersal potential.

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 and lower midlands (7-914 m a.s.l.) and appear to be generalists in a variety of rainforest biotopes including terra firme, dry and humid tropical forests, in gallery forests, and savanna forest patches. In these forests, they are commonly found in big trees with vines and epiphytes, in suspended medium to large-sized dry leaves, and in dense vine tangle plus leaves with light bamboo occurrence. Individuals can be found from January to December, 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: Pouteria reticulata ssp. reticulata cf.; Sloanea cordia ; Browneopsis ucayalina ; Talisia bitter; Mouriri guapira ; Trichilia solitudinis ; Eriotheca globosa cf.; Sloanea 1; Trichilia solitudinis ; Simira cordifolia /rubescens cf.; Sarcaulus brasiliensis aff. “burnt”; Catatola costaricana aff.; Pourouma mollis ssp. triloba cf.; Alchornea triplinervia cf.; Duguetia surinamensis cf.; Casearia avitensis cf.; Nectandra crassiloba cf.; Trichilia rubra cf.; Coccoloba densifrons cf. traditional; Iriartea deltoidea ; Micropholis venulosa cf.; Sagotia racemosa ; Virola obovata ; Pouteria baehniana cf.; Pourouma bicolor ssp. bicolor cf.; Inga bourgonii cf.; Garcinia macrophylla cf.; Chrysobalanaceae surreptitious ; Oenocarpus bataua ; Neea dive-tuberculate; Semaphyllanthe megistocaula cf.; Lauraceae redvein.

Geographic distribution

(Fig. 11 ). This species is currently known from the type locality in French Guiana and nearby areas and from Bolivia, Brazil - (Amazonas, Sergipe), Colombia, Ecuador, Guyana, Perú, and Suriname.

Notes.

Reichardt (1971) synonomized the following species with H. tuberculata Dejean. We do not agree with this based on the numerous attributes we studied and included in the descriptions.
