Hydatothrips gliricidiae Mound & Marullo

( Figs 6 , 12 )

Hydatothrips gliricidiae Mound & Marullo, 1996: 161 .

Female macroptera. Colour: body mainly yellow, head, anterior two thirds of metanotum and tergites II–III and VII brown, tergites I and IV–V pale; antennal segments I–II pale, III yellow with apical third shaded brown, IV brown with apex and base yellow, V yellow basally and increasingly darker to brown apex, VI–VIII brown; legs yellow with shaded brown areas medially; fore wings with three pale and three brown bands, apex pale.

Structure: Occipital apodeme confluent with posterior margin of eyes, ocellar area transversely striate without internal markings; pronotum with anterior area transversely striate forming a few transverse reticles without markings between the major lines, blotch distinct ( Fig. 6 ); mesonotum transversely striate with several minute microtrichia-like lines, metanotum with transverse striae on anterior half, longitudinal striae on posterior half with internal lines ( Fig. 12 ); fore wing second vein with two setae; posteromarginal comb on tergites II–VI incomplete medially, VII–VIII complete; tergite IX with with 4 pairs of mid-dorsal setae; sternites III–V and VII without microtrichia medially, VI with a few rows of microtrichia medially.

Male macroptera. Similar to female, but smaller and with darker abdominal tergites VII–VIII. Sternite VII with a small circular pore plate.

Larva II. Yellow without markings; antennae 7-segmented; thorax without brown sclerotized areas; body with setae short, with broadly expanded apices ( Mound & Marullo 1996).

Material studied. Holotype female and two paratype males, COSTA RICA, Braulio Carrillo NP, Volcan Barba Station (2500 m), on Malaise trap, vi.1990 ( BMNH) .

Comments. Associated with Gliricidia leaves in Central America, this species is unique amongst Neotropical Hydatothrips in having the fore wing with three pale and brown bands. It is also the only species in this genus that has several microtrichia-like structures both on the mesonotum and metanotum. In the Holarctic area, Sericothrips species bear microtrichia on the metanotum, but differently from H. gliricidiae , and have the entire surface of the abdominal tergites covered with microtrichia and a more transverse metasternal plate.
