Dorillus or Doryllus

Aristophanes, fragment 382 Kassel and Austin (tr. Jeffrey Henderson, with his note):

(a) δορίαλλος or δόριλλος in Ar. (quote) is used of the female genitals, to insult the tragedian Dorillus.⁹⁵

(b) δορύαλλος: the female genitals . . . referring to the tragedian Doryllus:

         the women fence off their pussy shelleys

⁹⁵ Or possibly Dorilaos; punning in any case on περίαλλος (loins).

(a) Etymologicum Genuinum AB

δορίαλλος· λέγεται καὶ δόριλλος. Ἀριστοφάνης· αἱ—φράγνυνται. ἔστι δὲ τὸ γυναικεῖον αἰδοῖον, ἐφ᾿ ὕβρει τραγῳδοποιοῦ Δορίλλου.

(b) Hesychius δ 2230

δορύαλλος· τὸ τῶν γυναικῶν μόριον . . . ἐφ᾿ ὕβρει τοῦ τραγῳδοποιοῦ Δορύλλου·

        αἱ <δὲ> γυναῖκες τὸν δορίαλλον φράγυνυνται

Because of the shape (triangular, like an upside down delta) of his beard?
