Derivation
of specific epithet.
The species epithet
''
vestiverdis
" is a Latinized feminine noun meaning green vest, referring to the two lobes of color on the pronotal disc on individuals of this species with central line of pale color bisecting the pattern and appearing as an open vest.
Proposed English vernacular name.
Leprechaun humps-backed beetle.
Diagnosis.
With the attributes of the genus and
angulicollis
species group as described above and adults with only dark slightly-metallic markings on the pronotal disc, elytra olivaceous, markedly shiny, some individuals with hint of metallic green near basal margin, narrow, with slightly arcuate lateral margin.
Description.

Size
: See Appendix 1. Length (SBL) short for genus, ABL = 3.46-4.62 mm, SBL = 3.14-3.99 mm, TW = 1.83-2.55 mm.

Hyboptera vestiverdis

B
Hyboptera scheelea
Erwin & Henry, sp. n., female, ADP007575.
Color: See
diagnosis, above.
Luster
: Very shiny elytra, not iridescent.
Microsculpture
: Mostly isodiametric and slightly stretched, shallowly impressed, cells somewhat more stretched around elytral tubercles.
Head
: Rugae moderately coarse, mostly transverse, somewhat curved on occiput. Eye very large, nearly perfectly hemispheric, evenly rounded. Antenna short, barely reaching humerus. Labrum rectangulate, shallowly bilobed, anterior margin slightly emarginate. Neck finely transversely rugose.
Prothorax
: Pronotum markedly broad, disc planar, with dense transverse rugae. Lateral margins broadly explanate and obtusely angulate medially, then markedly arcuate to obtuse hind angle, base medially produced and rounded posteriorly.
Pterothorax
: Normal for
Agrina
, fully winged. Elytron intervals 3 with 7 and 5 with 5(6) elongate unisetiferous tubercles, other intervals 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 unknown; males with only the lateral pair of longer setae on sternum 6.
Male genitalia
: Phallus (Fig.
5C
) with ostium of 1/5 its length, catopic, apex moderately long, narrowly rounded; 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 capable of flight. They are moderately swift and agile runners. Specimens have been acquired in Malaise traps and using insecticidal fogging methods.
Way of life.
Adults are common in the lowlands (116 to 356 m.a.s.l.) and appear to be generalists in a variety of rainforest biotopes including terra firme and
varzea
. In these forests, they are commonly found in big trees with vines and epiphytes, in
suspended
dry leaves, in dry
Scheelea
sp. and
Astrocaryum chambira
Burret palm frond skirts, in dry leaves scattered in vine tangles, and in dry leaves of the bamboo
Guadua weberbaueri
Pilg. Individuals can be found in January-February, May-July, and September-October, 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:
