Hyalopterothrips Priesner

Anaphothrips (Hyalopterothrips) Priesner, 1939a: 130 . Type species Anaphothrips (Hyalopterothrips) crocatus Priesner.

The species in this genus are characterized by the following set of characters ( Priesner 1964; Bhatti 1978): largesized, robust body, macropterous. Head with two pairs of anteocellar setae, interocellar setae long. Pronotum with two pairs of long posteroangular setae. Ferna divided ( Fig. 11 ). Lower vein of fore wing with only four setae, posterior fringes wavy. Abdominal tergite VIII without comb. Male tergite IX with two pairs of short stout thornlike setae; sternites III–V or VI each usually with a transverse and two rounded pore plates.

When Priesner (1957) described subtribe Anaphothripina, he characterized it by having no long setae on prothorax "Prothorax an den Hinterecken ohne längere, niemals mit 2 solchen Borsten jederseits". However, Priesner (1939a) had described Hyalopterothrips as a subgenus of Anaphothrips with the following comment: "The following is an interesting new which is difficult to place; its appearance is that of an Anaphothrips but the prothorax bears two pairs of fairly well developed, hyaline, posteroangular bristles. I consider it as the representative of a new subgenus". He retained Hyalopterothrips as a subgenus in his later works (see Priesner 1939b, 1949). Bhatti (1963) raised subgenus Hyalopterothrips to full generic status, and later included it in Anaphothrips genus-group ( Bhatti 1978). Hyalopterothrips and two other genera from Anaphothrips -group, Helenothrips and Tameothrips , all include species with two pairs of long posteroangular setae. The genus is distinguished from Helenothrips as follows: In female, abdominal tergite VIII with no posteromarginal comb (vs. with posteromarginal comb), tergite X without short thorn-like setae S1 (vs. with a pair), and sternite III with no pore plates (vs. with a pair). Hyalopterothrips is distinguished from Tameothrips by divided prosternal ferna (vs. undivided), and with stout ocellar setae pair III and posteroangular setae on pronotum (vs. with no such stout setae) ( Masumoto & Okajima 2017). setae S6 on the abdominal tergites II–VI inserted in front of the posterior margin.
