Parosmylus Needham, 1909

( Fig. 22 )

(= Mesosmylus Krüger, 1913c: 280 . Type species: Osmylus naevius Navás, 1912: 184 )

(= Phlebosmylus Navás, 1928: 94 . Type species: Phlebosmylus tancrei Navás, 1928: 95 ) syn. nov.

Type species. Parosmylus prominens Needham, 1909: 209 (by original designation).

Diagnosis. Wings elongate, ovoid; FW with irregular mottled infuscation; HW mostly hyaline except for

pterostigma wing margin and wing base; FW subcostal veinlets often forked near wing margin distally, interlinking crossveins absent; RP with only outer gradate series present in both wings, sometimes not discernible; dense crossveins throughout much of both wings; RP1 originating on RP close to fork of RA; FW M fork close to, or opposite to origin of RP1; FW cubital area often with crossveins present; male gonarcus posteriorly strongly sclerotised, entoprocesses rounded, well sclerotised and projecting; female genitalia with spermathecae oval.

Comments. Some authors consider Parosmylus a synonym of Osmylus (e.g., Banks 1913; Nakahara 1914) but following Wang & Liu (2009) we consider it sufficiently different to keep it as separate for now. Phlebosmylus Navás is known only from the original description and the type of the sole species in the genus has been destroyed. Only some wings characteristics are discernible about this genus from the description by Navás (1928), including that the genus is similar to Osmylus , except for some wing characteristics such as the presence of one row of gradates, which supports placement in Parosmylus .
