Typhlocyba casta |
| description |
A pale yellowish species, with a yellowish-white to light yellow head, pronotum, and scutellum; sometimes the scutellum is a deep yellow to yellowish-brown. The wings are yellowish-white to whitish with a dark brown transverse band across the middle of the wings. This band is oblique on the corium (outer part of the wing), curving downwards to the costal margins (instead of transversing straight across the wings); this band is narrow and sometimes consists of only several spots or slight traces of of brown near the costal margin. The transverse band is as bold as, but not bolder than the dark brown infuscations around the apical crossveins: the spots around the apical crossveins form a band of their own, typically consisting of four spots in the inner three basal and first apical cells to eight or nine spots in these cells. Individuals that only have four spots making up the apical band usually lack a median transverse band. The abdomen has the dorsum of each segment black on the basal half; the underside of these segments is black in males, yellow or white in females. Adults are 3.25-3.75 mm long. (Christian, 1954)

| comments |
Christian, 1954 stated that the series of specimens collected on Quercus sp. from Franklin, NC differed from typical casta specimens in being slightly larger and having the median transverse band sharply distinct with smooth margins; the ground color was an opaque light yellow. Due to these differences, Christian noted that this form could be a distinct species. If individuals matching this description are found, it is important for them to be collected in order to determine if they truly are separate species. |
