It is a member of the Megalurothrips genus-group with the following characters in common: Antennae 8-segmented, ocellar setae pair I present, median metanotal setae at anterior margin, metanotal spinula absent, abdominal
tergite VIII with posteromarginal comb usually interrupted, sternal discal setae absent (Mound and Palmer, 1981).
Variation: face smooth; opening pocket like structure without a longitudinal opening in the central surface; hind wing with distal abscissa of Cu1 meeting cu-a equidistant between 1A and M;
tergites II-IV orange with two black spots in the distal corners;
tergite V entirely black.
Head yellow pruinose or silvery grey when viewed from certain angles; ocellar setae weak almost not differentiated from ocellar triangle setulae; scutellar dorsum brown with brown pruinosity; calypters yellow with light brown pruinosity; abdomen dark brown in ground colour (or dark brown with sides reddish-brown in one specimen) with
tergites 3 and 4 each with irregular band of grey pruinosity on anterior fifth and faint light brown pruinosity posteriorly in posterodorsal view;
tergite 5 with yellow pruinosity, denser ventrally; syntergite 1+2,
tergites 3 and 4 each with a spot of dense grey pruinosity on midventral margin in posteroventral view.
8-10):
Tergites 1 to 4 weakly sclerotized,
tergites 6 and 7 completely sclerotized,
tergite 8 as narrow sclerotized band, all
tergites with single row of setae along posterior margin, trichoid sensilla absent.
This genus is characterized by a cup-shaped ninth abdominal
tergite, posteriorly with spines pointing downward far apart laterally, and tenth abdominal
tergite without spine-like process.
Synonyms and re-descriptions of both male and female were given and diagnostic characters as both male and female having slightly waisted abdomen,
tergite 3 in male being orange while in female it is black and the spurious vein in female touching the M1 vein.
T2 with two short, slightly pubescent basal foveae, rest of
tergite smooth except for reticulate microsculpture along narrow hind margin, T3-T6 with similar microsculpture over most of surface and a few very inconspicuous setae.
Specifically, he mentioned (i)
tergite 9+ectoproct--separate in Kimochrysa (as opposed to fused in Hypochrysa, both sexes), (ii) male ectoproct in Kimochrysa-- lacking a long, slender "appendage" (probably the apodeme) that occurs in Hypochrysa, and (iii) subgenitale (female)-- unsclerotized in Kimochrysa (as opposed to sclerotized in Hypochrysa).
Tergites. They are present as follows: not sclerotized, lighter in color than carapace, dark yellow, most tergal setae short with terminal denticulations,
tergite XI with 2 long and simple setae,
tergites incompletely divided with narrow median line;
tergite XI not divided, and tergal chaetotaxy is shown in Table 3.
The maximum width of the specimen is 22.7 mm at
tergite 4.
