Type
species:
Gynaikothrips tristis
Karny
, by original designation.
No species of this genus is recorded from
China
, but two are described from Java, one from the
Philippines
, and one from
Fiji
. The
holotype
and
paratype
females of
longisetosus
Reyes
have been studied (in ANIC), and antennal segment IV has three sensoria not two as given in the original description (
Reyes 1994
). This genus belongs to the
Liothrips-
lineage, in which antennal segments III–IV have one and three sensoria respectively, and the prosternum lacks basantra, but in contrast to most species in that group the species of
Adelphothrips
have two pairs of equally well developed postocular setae (
Fig. 118
). Another species from the
Philippines
,
Adelphothrips ignotus
(Reyes)
comb.n.
,
is here transferred from
Mesothrips
because it has the character states typical of
Liothrips-
lineage. The only known specimen of
ignotus
(in ANIC), a male with expanded fore femora but no fore tarsal tooth, has the notopleural suture slightly incomplete on the right side, but complete on the left, and the metathoracic sternopleural sutures are well-developed.

Diagnosis
: Head with cheeks slightly or distinctly narrowed at base; 2 pairs of postocular setae welldeveloped, one pair well posterior to the other (
Fig. 118
); stylets usually about 1/3 of head width apart, retracted to postocular setae; antennae 8-segmented, III with 1 sensorium, IV with 3; pronotum with 5 pairs of well-developed setae, notopleural sutures incomplete or complete; basantra absent; mesopresternum transverse, sometimes narrow medially; sternopleural sutures absent or present; fore tarsal tooth absent in both sexes; fore wings parallel-sided, with duplicated cilia; pelta triangular; tergites II–VII with 2 pairs of wing-retaining setae; tube with straight sides, slightly shorter than head.
