(loc. no. 343)
. –
Holotype
is in good condition: (1) glued on a pointed card by its hind part of mesosternum and hind pair of coxae, (2) right fore wing distally and longitudinally somewhat creased.
Holotype
is deposited in the Hungarian Natural History Museum (

Etymology – The species name
“cubiculus
” refers to the cubicformed head.
Description of the female
holotype
. – Body
2.2 mm
long. Antenna one-sixth longer than body and with 27 antennomeres. First flagellomere 3.2 times and penultimate flagellomere 2.7 times as long as broad. – Head in dorsal view cubicform (
Fig. 24
), 1.53 times as broad (between temples) as long, temple just longer than eye, temple a bit swollen, occiput excavated. Eye in lateral view almost twice as high as wide, temple 1.2 times wider than eye and beyond eye narrowing ventrally. Inner margin of eyes slightly converging ventrally, face quadrate: slightly wider above than high (
Fig. 25
). Mandible broad, 1.3 times as long medially as broad between upper and lower teeth, second and fourth teeth pointed (
Fig. 26
). Head polished.
Mesosoma in lateral view elongated, 1.6 times as long as high, polished. Notaulix feebly distinct on declivous part of mesoscutum; prescutellar dimple linearform; mesoscutum evenly hairy. Precoxal sulcus narrow, subcrenulated. Propodeum rugose, with hairs on its postero-lateral part. Hairy rosette of mesopleuron less distinct. – Hind femur 3.8 times as long as broad distally (
Fig. 27
). Hind tarsus somewhat longer than hind tibia.
Fore wing as long as body. Pterostigma (
Fig. 28
) ten times as long as wide, parallel-sided,
r
somewhat longer than width of pterostigma;
1–R1
0.6 times as long as pterostigma (
Fig. 28
, see arrows),
3–SR + SR1
ending before tip of wing, marginal cell narrow. First subdiscal cell closed, i.e.
CU1b
present though feebly sclerotized (
Fig. 29
, see arrow).
First tergite (
Fig. 30
) 1.3 times as long as broad behind, evenly broadening posteriorly, pair of basal keels not meeting and reaching middle of tergite; tergite with a few striates, interstriations rather transversely rugulose, bare. Second tergite medially subgranulate, otherwise together with further tergites polished. Hypopygium less pointed, ovipositor sheath short (
Fig. 31
).
Scape and pedicel brownish yellow, flagellum brown to dark brown. Head and mesosoma black. Mandible ochre, palpi yellowish. Tegula brownish yellow. First tergite black with rusty tint, metasoma beyond first tergite ochre yellow, hind tergites darkening brownish. Legs deep yellow, fifth tarsomere brown to dark brown. Wings hyaline, pterostigma and veins light brown.
Male and host unknown.

(

) viewing their common features as the cubicform head and elongate mesosoma, however, the two species are different by the following features:
1 (2) First tergite more broadening posteriorly, 1.3 times as long as broad behind; second tergite medially subgranulate (
Fig. 30
). Temple in dorsal view a bit swollen (
Fig. 24
). Inner margin of eyes converging ventrally, face somewhat wider above than high (
Fig. 25
). Mandible broad, 1.3 times as long medially as broad between upper and lower teeth (
Fig. 26
). Hind leg entirely yellow. Metasoma beyond first tergite ochre yellow, hind tergites darkening brownish. f:

1 (2) Temple in dorsal view swollen, i.e. head between temples a bit broader than between eyes (
Fig. 24

evenly broadening posteriorly; second tergite antero-medially subgranulate (
