Description of
holotype
,
♀
. Body length:
1.8 mm
; fore wing length:
1.6 mm
.
Color
. Honey yellow. Stemmaticum black. Palpi whitish yellow. Antenna yellow with apical segments darker, brown. Metasoma with T2+3 whitish, reminder apical terga dark brown. Wings hyaline with two faintly fuscous bands, stigma and venation pale yellow. Legs pale yellow.
Head
. Length of head in dorsal view 0.54× longer than wide. Antenna about as long as body; scape 2.0× longer than wide; flagellomeres 13–17 with weak expansion apical-ventrally. Eye height 2.1× malar space. Sculpturing mostly finely areolate-rugulose. Malar suture present.
Mesosoma
. Mesoscutum finely areolate-rugulose. Notauli absent. Pronotum smooth with a rugose groove. Propleuron costate. Scutellar sulcus with 7 divisions, scutellum punctate. Mesoscutellar trough weakly costate. Metanotum rugose. Propodeum with complete pentagonal areola extending over its entire length; anterior aspect weakly rugose, otherwise smooth and polished; with a pair of lateral carinae; transverse carina present but interrupted at areola; all carina well defined. Mesopleuron coriaceous, with relatively shallow and finely crenulate sternaulus. Metapleuron strongly rugose-costate.

Wings

R1 0.7× stigma length; stigma about 2× longer than high.

sp. n.
, ♂ paratype. 16, head, frontal; 17, head, lateral; 18, mesonotum; 19, mesosoma, lateral; 20, propodeum; 21, metasoma, dorsal. Scale bar = 100 µm.
Legs
. Hind legs with inner tibial spur about 0.25× tibia; tibia 4.7× longer than maximum width. All legs punctate except for coxae smooth. Mid coxa with distinct transverse sulcus dorsally.
Metasoma
. Entirely smooth
Variation
. Metanotum dark brown. Scutellar sulcus with 7 divisions. All flagellomeres dark brown.
Male
. Body length 1.1–1.8. Fore wing length 1.0–1.6. Males are essentially appearing similar to females, but usually with wing bands being fainter (sometimes nearly imperceptible without proper light and background). There are no distinct expansions of median to subapical flagellomeres in males. Most males have mesoscutellum laterally brown or dark brown. The metapleuron is less sculptured, sometimes entirely coriaceous, especially on smaller male specimens. Rarely the apical metasomal terga are yellow.
Diagnosis
.
Adelius caatinga
sp. n.
is a mainly yellowish species, with the metasoma white subbasally and darker apically. The wings have two faint (sometimes virtually absent) fuscous bands, vein r of fore wing absent, and fore wing vein R1 long (about 0.7 as long as stigma). The hind coxa is smooth. Specimens with more lightly banded wings are similar to
A. janzeni
sp. n.
, differing from it mainly by the areolate-rugose head, which is mostly smooth and polished in
A. janzeni
.
However, some specimens (especially males) have very faint fuscous bands which are mostly imperceptible. These specimens might run to
A. bolivariensis
in our key to species, since these two species are very similar in color pattern and other diagnostic characters, including a relatively long vein R1 (more than 0.6× longer than stigma length).
Adelius caatinga
differs from
A. bolivariensis
by having the apex of antenna always darker, as compared with the antennal apex entirely yellow in
A. bolivariensis
. The tibiae of all legs are yellow basally in
A. caatinga
, without the contrasting white subbasal band that is present in all tibiae of
A. bolivariensis
. In addition, the face of
A. caatinga
is areolate-rugulose but in
A. bolivariensis
the face is mostly transversely striate.
Biology
. Unknown.
Distribution
. Found in the Brazilian states of
Bahia
,
Minas Gerais
and
Piauí
. Sampled in Caatinga vegetation.
Etymology
. This species is named in reference to its distribution over the Caatinga biome in the semi-arid region in northeastern
Brazil
. Caatinga is the fourth largest Brazilian biome, and covers about 10% of its territory, being the only region entirely within the country’s limits. There are several different vegetation
types
in the region, ranging from deciduous broadleaved forest to mostly open areas with sparse short shrubs.
