Mycotretus episcaphoides Crotch, 1876: 456 . Type locality: “Ega” [= Tefé, in the state of Amazonas, North Brazil].

Mycotretus episcaphoides – Gemminger & Harold 1876: 3692. — Kuhnt 1909: 71; 1911: 49. — Blackwelder 1945: 466. — Alvarenga 1994: 25. — Skelley 1998b: 17.

Other specimens examined

ECUADOR • 1♂ (dissected); “ ECUADOR [printed] Napo-cuyabeno , 230 m, nov 17/85 [?][handwritten], Legit [printed] E. cotyiozo [?] [handwritten] \ Callischyrus n. sp. [handwritten]”; MNRJ .

Distribution

North Brazil ( Alvarenga 1994).

Remarks

Mycotretus episcaphoides resembles M. floriger ( Fig. 29F View Fig ) in body shape and morphology of male genitalia. The penile flagellum of M. episcaphoides is less sclerotized than that of M. floriger . Male genitalia of both species have a sinuosity at the anterior one-third of the flagellum virga. That sinuosity is strongly sclerotized in M. floriger and desclerotized in the examined M. episcaphoides . This morphology of the penile flagellum resembles that observed in M. chilensis Crotch ( Fig. 4F View Fig ) and M. trifasciatus Guérin ( Fig. 22A View Fig ) ( Pecci-Maddalena & Lopes-Andrade 2017).
