Etymology.
Named by Bondar (1942) in honour of his great friend Antonio Margarinos Torres.
Remarks
.
Bondariella torresi
(
Fig. 1
B),
Bondariella rudicula
sp. nov.
(
Fig. 2
B) and
Bondariella crenata
sp. nov.
(
Fig. 2
C) are similar by having integument evenly light reddish brown throughout. But
Bondariella torresi
is easily distinguished from
Bondariella rudicula
sp. nov.
and
Bondariella crenata
sp. nov.
by a number of characters: sutural interval of elytra with two rows of scales; remaining elytral intervals with 2–3 rows of scales on base, becoming variously two rows toward apex; rostrum curved (males), strongly curved and long (0.9 times as long as pronotum, females) (
Fig. 1
B); interprocoxal distance larger (1.2–1.3 times) than procoxal diameter; metatibae bearing a comb of long setae on distal ½ (male); abdominal tergites (
Figs. 3
G, 5A) with median fissure complete (reaching distal margin of tergite IV); ventrite V (
Fig. 5
B) transversally oblong (3.3–3.6 times wider than long); sternum VIII (
Fig. 5
C) trapezoidal bearing six posteroventral setae; tegmen (
Fig. 5
E) with dorsal parameroid lobes free (not connected medially on base) and; endophallus (
Fig. 5
F) membranous, with a pair of bags of spinules. On the other hand,
Bondariella rudicula
sp. nov.
and
Bondariella crenata
sp. nov.
have only one row of scales on sutural interval; remaining elytral intervals with 1–2 rows at base, becoming variously only one row toward apex; rostrum almost straight (males), straight and short (0.5–0.6 times as long as pronotum, females) (
Figs. 2
B–C); interprocoxal distance slightly shorter (0.9 times) than procoxal diameter; metatibae lacking comb of setae; abdominal tergites (
Fig. 3
F) with median fissure incomplete (not reaching distal margin of tergite IV); ventrite V (
Figs. 8
B, 9B) trapezoidal (2.4–2.6 times wider than long); sternum VIII (
Figs. 8
C, 9C) subquadrate and glabrous; tegmen (
Figs. 8
E, 9E) with dorsal parameroid lobes connected medially on base; endophallus (
Figs. 8
F, 9F) sclerotized, lacking membranous bags. Finally,
B. torresi
is distributed in Caatinga biome and has only been collected from
Syagrus vagans
while
Bondariella rudicula
sp. nov.
and
Bondariella crenata
sp. nov.
are distributed in Amazon biome and have only been collected from
Euterpe
species. The remaining species of
Bondariella
have been collected from different species of
Syagrus
.
Natural history.
Bondariella torresi
is recorded from the Caatinga biome, from Lajedo Alto and Morro do Chapéu, both localities in Bahia,
Brazil
. Adults and larvae of
B. torresi
were collected from
Santa Luzia
, Lajedo Alto on male flowers of
Syagrus vagans
, locally known as “ariri” (Bondar 1942, 1943, cited as
Cocos vagans
Bondar
). In the municipality of Morro do Chapéu, adults were collected on an unidentified palm. Larvae feed and complete their life cycle between petals of male flowers from open inflorescences of
S. vagans
(Bondar 1942, 1943). Bondar was able to rear larvae of
B. torresi
in the laboratory, but larvae and pupae not yet been described. Currently, Lajedo Alto (ex Lagedo Alto) is district of the municipality of Iaçu, which was dismembered from the municipality of Santa Teresinha (ex Santa Terezinha) (IBGE 2011). As spelled in the labels from
type
material we did not find the locality of Santa Tereza, so we believe that it could be the municipality of Santa Teresinha (ex Santa Terezinha) mispelled as Santa Tereza. To corroborate this interpretation, in the same paper, Bondar (1942) spelled Santa Teresinha or Santa Terezinha in labels of other two species of weevils collected on flowers of
S. vagans
. In additional collections besides the
type
series,
Bondariella torresi
has only been recorded on flowers of
S. vagans
(for details see natural history of
Bondariella
).
