Type species: Allobrinckina belousovi Kaplin , sp. n., designated here.

DESCRIPTION. Body relatively long, devoid of pigment with typical multiradiate scales on body and coxae of legs, lacking on head. Antennae slightly shorter than body. Pedicellus of male with relatively long finger-shaped apophyses on medial face and well-developed fovea ( Figs 1 , 13 ). Mandibles strong with welldeveloped molar, incisor region with 7 incisives ( Fig 3 ). Maxillae of usual form,

galea with two apical conules, lacinia with pectinate prostheca ( Figs 4, 5 ). Ultimate palpomere of maxillary palps with six papillae of usual form. Ultimate palpomere of labial palps with six papillae of usual type. Apical parts of glossae divided into two lobes ( Figs 15 , 23 ).

Thorax practically not wider than the abdomen. Posterior margin of all thoracic tergites with 1 + 1 submedian and 2 + 2 sublateral macrochaetae, first of lateral macrochaetae of thoracic tergites very long, about 0.4 their length ( Fig 22 ).

Legs quite elongate. Coxae and femora of male and female widened. Tarsi with two rows of stout macrochaetae along its ventral surface ( Fig 6 ). Praetarsus with two strong claws covered by microtrichia on their basal half, without medial empodial claw. Between claws instead of the empodium there is a slightly convex support oval platform with 5–6 transverse ribs in both sexes ( Fig 8 ).

Urotergites I–IX with 1 + 1 submedian and several sublateral and lateral macrochaetae ( Figs 9, 10 ). Urotergite X trapezoidal with well-developed rounded posterior emargination. Posterolateral corners of urotergite X of female with 1 + 1 long apical bifurcate macrochaetae ( Fig 12 ). Urotergite X of male with 16 + 17 lateral pegs and with simple macrochaetae near the inner part of pegs areas, several of them form two longitudinal rows ( Fig 11 ).

Urosternite I divided into a median sternite and two lateral coxites ( Fig 16 ).

Urosternites II–VII in female and II–VIII in male entire, styli on urosternites II–IX,

1 + I eversible vesicles on urosternites II–VI and 1 + 1 pseudovesicles on urosternite VII ( Figs 17–19, 21 , 25 ). Posterior angle of sternite I acute ( Fig 16 ). Posterior part of urosternites II–VII with two pairs of relatively long and thin apically bifurcate setae between eversible vesicles. Subgenital plate of female well-developed, suboval

( Fig 24 ).

Parameres long reach to about 0.55 the length of styli, about six times longer than wide ( Fig 21 ). First basal divisions of cerci of male with 1 + 1 preserved inner pegs.

Ovipositor slightly longer than styli IX, gonapophyses with 11–12 divisions ( Fig 25 ).

RELATIONSHIPS. Allobrinckina gen. n. as Pseudobrinckina Mendes, 2002

from Thailand devoid of empodium, with scales on body and coxae, lacking on head. Allobrinckina gen. n. is the first described Coletiinae and Nicoletiidae with a slightly convex support oval platform with 5–6 transverse ribs between claws of pretarsus in both sexes. Posterior notch of urotergite X in female of Pseudobrinckina with 2 + 2, Allobrinckina gen. n. with 1 + 1 long and robust posterolateral macrochaetae. Apical part of glossae in female of Pseudobrinckina not divided and in clypeus, labrum, antennae (scapus, pedicellus with apophyses, basal part of flagellum); 2 –

maxillary palp; 3 – distal part of mandible; 4 – galea of maxilla; 5 – lacinia of maxilla; 6 –

fore leg; 7 – inner ventral part of fore femur; 8 – hind pretarsus and 3rd tarsomere. Scale bars

= 0.1 mm.

(12, 14): 9 – urotergites I–III; 10 – urotergite IX; 11, 12 – urotergite X; 13 – pedicellus with apophyses and fovea; 14 – scapus, pedicellus and basal part of flagellum; 15 – labial palp and ligula. Scale bars = 0.1 mm.

female and male of Allobrinckina gen. n. divided into two lobes as in Squamatinia .

Male pedicellus of Allobrinckina gen. n. with well-developed apophyses and fovea.

Among Nocoletiidae fovea also described only in males of Lepidospora and Brinckina

(Mendes, 1994).

ETYMOLOGY. The new genus is named after its probable closeness to Pseudo-

brickina Mendes, 2002.
