Holotype.

Male. Ecuador, Orellana, Yasuni National Park (edge), 95.43 km E (heading 101.46°) Coca, Tiputini Biodiversity Station, Erwin Harpia Plot: transect 4, station 4, 0.6316°S, 76.1443°W, 208m, 8 February 1999 (TL Erwin, et al.)(NMNH: ADP135781).

Derivation of specific epithet.

The specific epithet, " tiputini " is used as a noun in apposition and is based on the Tiputini Biodiversity Station in the Yasuni area of eastern Ecuador in reference to one of the places in which members of this species are found.

Proposed English vernacular name.

Tiputini humps-backed beetle.

Diagnosis.

With the attributes of the genus and angulicollis species group as described above and adults with patches of bright metallic green para-medially on pronotum, elytra markedly shiny, violaceous, some individuals with hint of metallic green near basal margin, broad, with markedly arcuate lateral margin.

Description.

(Figs 4A , 5D ). Size: See Appendix 1. Length (SBL) long for genus, ABL = 4.21-5.64 mm, SBL = 3.33-4.72 mm, TW = 1.868-2.92 mm.

Color: See diagnosis, above.

Luster: Matte with a few green reflections, markedly iridescent.

Microsculpture: Mostly irregular isodiametric, often stretched, shallowly impressed, cells especially stretched around elytral tubercles.

Head: Rugae moderately coarse, transverse. Eye very 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 markedly broad, disc medially shallowly depressed along midline, and with dense transverse rugae. Lateral margins broadly explanate and obtusely angulate medially then subtlely arcuate to obtuse hind angle, base medially produced and rounded posteriorly.

Pterothorax: Normal for Agrina , fully winged. Elytron interval 3 with 7(8) and interval 5 with 5 unisetiferous tubercles, other intervals shallowly to moderately convex, side margin broadly explanate laterally only at middle third. Elytron broad and short, slightly narrower than 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 unknown.

Male genitalia: Phallus (Fig. 5D ) with ostium of 1/5 its length, catopic, apex moderately long, narrowly rounded, broad in dorsal aspect; endophallus with flagellum (mid-part 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 probably capable of flight. They are moderately swift and agile runners.

Way of life.

Adults are common in the lowlands and lower midlands (20 to 900 m a.s.l.) and appear to be generalists in a variety of rainforest biotopes including terra firme, várzea, and igapó. In these forests, they are commonly found in big trees with vines and epiphytes, in suspended dry leaves, 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: Pseudolmedia laevis ; Iriartea deltoidea ; Castilla ulei cf.; Sorocea steinbachii cf.; Matisia malacocalyx cf. Swartzia león; Eschweilera coriacea cf.; Mouriri guapira ; Trichilia solitudinis ; Eriotheca globosa cf.; Sloanea 1; Vismia weedy; Tabebuia moby ; Pourouma bicolor ssp. bicolor cf.; Alchornea triplinervia cf.?; Naucleopsis krukovii cf.; Hyeronima oblonga ; Clarisia biflora ; Pouteria baehniana cf.; Inga cuadra ; Maquira calophylla ; Brownea grandiceps cf.; Talisia bitter; Virola decorticans cf.; Pouteria cuspidata ssp. robusta cf.; Diospyros sericea ; Guarea silvatica ; Scheelea sp.
