Neohydatothrips tibialis (Priesner)

( Fig. 42 )

Sericothrips tibialis Priesner, 1924: 528 .

Female macroptera. Colour: mainly dark brown, tibiae and apex of femora yellow; antennal segments I–II yellow, III light brown, IV light brown with brown apical third, V–VIII brown; fore wing brown with one sub-apical pale area and apparently median and apical bands suffused brown to pale.

Structure: Occipital apodeme not confluent with posterior margin of eyes ( Fig. 42 ), ocellar area irregularly sculptured with internal markings; pronotal transverse striae forming some transverse reticles with internal markings, pronotal blotch distinct; mesonotum transversely striate; metanotal striae transverse on anterior half, longitudinal on posterior half; metasternal plate with shallow emargination; comb of microtrichia incomplete on tergites III–VI, complete on VII–VIII; tergite IX with 2 pairs of mid-dorsal setae.

Material studied. Cotype female, MEXICO, Chapingo, on alfafa field, 13.iii.1924 ( USNM).

Comments. Based on three poorly cleared females, this species was regarded as having only one pale area (sub-basal) on the fore wing, although the key by Mound and Marullo (1996) suggests that the fore wing has three pale bands. The cotype examined here is not fully cleared with the fore wing laying over the body, but the apex of the fore wing is light brown. In the original description, Priesner (1924) indicated that the species has one pale subbasal band also other more or less diffused brown bands.
