Genus Alphina Stål, 1863
Tribe Poiocerini Haupt, 1929
Subtribe Calyptoproctina Metcalf, 1938
Genus Alphina Stål, 1863.
Type species (in original combination): Alphina nigrosignata Stål, 1863.
Distribution: Southwestern US, Central America to northern South America (?)
This genus has three species.
Alphina fryi Distant 1906: 194 - Brazil
Alphina glauca (Metcalf, 1923) - USA: AZ, TX (reported probably in error: USA: MS, NC, TN)
= Crepusia glauca Metcalf, 1923: 173.
= Alphina glauca (Metcalf, 1923); comb. by Metcalf 1938: 348-349.
Alphina nigrosignata Stål 1863: 244 - French Guiana
Note: Because the type specimen of Alphina glauca (Metcalf, 1923), is misplaced, it is not possible to determine whether this species is the same as Calyptoproctus marmoratus Spinola, 1839. The type specimen of Alphina glauca is from Brownsville, Texas (paratypes from Arizona), and at least one potentially undescribed species is known from Texas, Arizona and Mexico. It is also evident that these species (i.e., Alphina glauca and Calyptoproctus marmoratus) are not properly placed in either Alphina or Calyptoproctus (or Crepusia), but it is not clear which genus these species should be placed. This problem is the subject of an ongoing study.
Known host plants:
None reported (but possibly on trunks of deciduous trees).
Head not strongly produced, head with eyes narrower than pronotum; transverse carina at posterior margin of pronotum; sides of frons not parallel, widened in distinct lobe just above clypeal suture; ninth abdominal tergite of female elongate, medially carinate, usually hiding tenth and eleventh; forewings almost translucent, mottled with dark and clear areas.

"Alphina glauca" comes to lights. It may be possible to find on the trunks of trees (Populus sp.?).
