Enneothrips gustaviae Hood

(Figs 13, 14, 24, 34, 44, 54, 64, 70)

Enneothrips gustaviae Hood, 1935: 144.

Body color brown (Fig. 13). Antennal segments I–II brown, III yellow, IV yellow at base and extreme apex, light brown medially, V yellow at base and light brown at apex, VI–IX brown (Fig. 24). Femora brown, except for extreme base of mid femur; fore tibia yellow with median brown shading, mid tibia brown at base and yellow at apex, hind tibia brown medially with base and apex yellow. Fore wing brown, with basal quarter pale (Fig. 54). Ocellar triangle with a few lines of sculpture sometimes advancing from surrounding area of head, ocellar setae III just outside the triangle; posterior area of head transversely striate but forming undefined reticles (Fig. 34); mouth cone not surpassing prosternum. Pronotum with undefined reticles anteriorly (Fig. 34). Mesonotum transversely striate posteriorly with about 15 lines of sculpture, anterior area lacking complete sculpture. Metanotum reticulate, without markings inside reticles (Fig. 44). Abdominal tergites II–VII with around 10 transverse lines of sculpture with short microtrichia on lateral thirds; VII with posteromarginal comb of short microtrichia incomplete medially and with lateral microtrichia more developed than on tergites II–VI; tergite IX with two pairs of campaniform sensilla (Fig. 64). Male smaller and with abdominal tergites IV, V and X light brown (Fig. 14); paired opening associated with internal gland close to antecostal ridge of abdominal sternite III (Fig. 70).

Material studied. Holotype female and paratypes males and females: Panama. Barro Colorado Island, on leaves of Gustavia superba, 29.vii.1933 and 14.viii.1933, 24 females and five males (J.D.Hood, J.Zetek & C. Marquinez col.) (USNM).

Comments. This species is unique in the genus and was retained by Moulton (1941) in a subgenus Enneothrips when he erected a subgenus Enneothripiella with E. flavens as the type species. This subgenus was distinguished due to the longer posteroangular setae, and lack of red pigmentation, in contrast to E. gustaviae in. In the first couplet of the key above E. gustaviae is clearly distinguished from all other members of the genus. However, these character state differences are not sufficient in confirming that the species represents a separate phylogenetic lineage requiring recognition at genus level. This species has been collected on Gustavia superba leaves and recorded only in Panama.
