, aedeagus
0.8 mm
. Maximum width of body parts (

0.9 mm
, pronotum
1.6 mm
, elytra

.
Body ovoid (
Fig. 1A
), convex (
Fig. 1B
), brown-black, anterior margin of clypeus and pronotal margins lighter, legs red-brown with reddish anterior tarsi, AI–AVII reddish, AVIII–AXI infuscate. Head with strigae in some places, pronotum without microsculpture, elytra with transverse strigae. Entire dorsum punctured. Underside almost entirely microsculptured by elongate cells oriented transversally or obliquely (
Figs 3B–C
).
Head.
Very coarsely punctured, transversely wrinkled, punctures connected by oblique or longitudinal transverse strigae in some places (
Fig. 1C
). Punctures separated by about 2–3 times their own diameter. Several short erect setae placed at clypeus and near eyes. AI–AVI with several setae, antennal club more densely setose (
Fig. 2B
). Ratio of length of antennomeres II–XI (AII = 1.0): 1.0: 1.4: 0.6: 0.5: 0.5: 1.1: 0.5: 1.2: 1.2: 1.9. Ratio of width of AII–AXI (AII = 1.0): 1.0: 0.9: 0.8: 0.9: 1.1: 2.3: 1.6: 2.8: 2.9: 2.5. W/L of AII–AXI: 0.7: 0.4: 0.9: 1.2: 1.3: 1.5: 2.2: 1.7: 1.8: 1.0.
Pronotum.
Very finely punctured, punctures separated by about 6–7 times their diameter, several larger punctures dispersed before base. Punctation coarser and denser near lateral margin. Base nearly straight for middle 8/10, obliquely angled toward hind angles, not bordered. Hind angles obtuse in both dorsal and lateral view (
Figs 1A–B
). Lateral margins bordered, roundly tapered from base towards anterior rounded angles as seen dorsally; in lateral view, margin slightly curved, and slightly downturned before hind angles. Anterior margin finely bordered.
Scutellum.
Triangular, sparsely finely punctate like pronotum, with abruptly rounded apex.
Elytra.
With nine rows of punctures, 9
th
row parallel to lateral margin (
Figs 1A–B
). Punctures in each elytral row separated by about 2–3 times their diameter. Intervals with irregularly distributed punctures that are distinctly smaller than those in rows, separated by about 4 times or more their own diameter. Punctures in rows and intervals equipped with transverse strigae. Strigae getting longer, connecting neighbouring punctures laterally, and apically becoming distinctly deeper. Apical part of elytra with transverse wrinkles created by presence of deep strigae (
Fig. 1B
). Epipleura visible in lateral view; with short yellow erect setae (setae not visible in dorsal view). Sutural stria fine, punctured, confined approximately to apical third of elytral length.
Legs.
TI–TIV of anterior and mid-tarsi of male feebly widened and bearing tenent setae ventrally (
Figs 3E,G
), same tarsomeres of female and hind tarsomeres of both sexes slender and with simple setae only ventrally (
Fig. 3H
); all tarsomeres dorsally with several stiff setae, anterior tarsomeres more densely setose on underside than others; empodia of all tarsi bisetose (
Figs 3G, H
). Anterior tibiae with tarsal groove at dorsal surface as long as tarsus (
Fig. 3B
, trgr). All tibiae with strong spines laterally (
Figs 3B,F,H
). Longest lateral spines approximately as long as TI, longest terminal spines a little longer than TI. Hind tibiae and femora without distinctive characters (
Fig. 3H
).
Mesoventrite.
Concave, abruptly falling between mesocoxae with short low rounded longitudinal carina (
Figs 3A,C–D
; msvc). Procoxal rest with low but distinct longitudinal central carina (
Fig. 3A,D
; prre).
Metaventrite.
Coarsely densely punctured with exception of strip before hind coxae (
Fig. 3A
). Punctures equipped with recumbent setae. Anterior process broadly rounded, reaching between mid-coxae; anterior process and portion of metaventrite behind mesocoxal cavities distinctly bordered (
Fig. 3A
).
Metathoracic wings
fully developed (
Fig. 2E
).
Abdominal ventrites.
Five visible ventrites, very finely punctured and setose (
Fig. 3H
). Without unusual characters.
Genitalia.
Aedeagus as in
Fig. 1D
; parameres with short apical and preapical medial setae. Ovipositor (
Fig. 1I
) with elongate but unusually broad proximal and distal gonocoxites, and small apical stylus (scarcely longer than wide). Spermatheca not sclerotized.
Variability.
The new species varies slightly in colour of dorsum from dark brown to almost black and colour of antennal club from light club almost coloured as AI–AVI to antennal club black. The head in some of the
paratypes
is very coarsely punctured but not wrinkled. The density of pronotal and elytral punctation varies – the pronotal punctures are separated by 2–4 times their own diameter in some
paratypes
to 6–8 times their own diameter in other
paratypes
; elytral rows of punctures are more densely punctured in some
paratypes
than in the
holotype
, separated by 1–2 times their own diameter.
Etymology.
The species name is a Latinized adjective derived from the name of the country of origin.
Distribution and biology.
The species has a wide distribution in
Chile
, from region IV (
Coquimbo
) in the north to region X (
Los Lagos
) in the south, and from coastal areas and mountains through the central valley to the Andes (
Fig. 7A
). Specimens have been collected in various kinds of indigenous forests (Valdivian rainforest and
Nothofagus
-dominant forests, with or without
Araucaria
trees or
Chusquea
bamboo understory, to drier forests and woodlands), at elevations from
100 m
to more than
1400 m
, mainly by use of flight intercept (window) traps, Berlese sampling of leaf litter, and pitfall traps. No fungus associations are known, but the compact body form and strong spinose legs suggest it may be associated with subterranean fungi, as is known or suspected for various other
Sogdini
species (e.g.,
NEWTON 1998
).
