Treatment

Phanoperla tuberosa View in CoL sp. n.

( Figs. 22‐25 View Figs )

Material examined. Holotype ♂ and 1 ♂ paratype from Indonesia, East Kalimantan, Long Tua, Bahau River , 3° 10’ N, 115° 47’ E, 440 m, 5‐9 April 1994, IIS 940526, B. Hubley, D.C. Darling (Holotype MZB, paratype ROM). GoogleMaps

Adult habitus. Frons pale brown, pronotum with pale brown rugosities; pronotal margins dark except for short section at anterolateral angles; median pronotal suture dark. Wings tinted pale amber, veins brown except for pale costal area. Femora pale brown, tibiae slightly darker.

Male. Forewing length 7 mm. Tergum 8 unmodified, tergum 9 with lateral and median sensilla basiconica patches fused into a single large trilobed patch. Hemitergal processes wide basally and tapered to point ( Fig. 22 View Figs ). Sterna 6‐7 with weak hair brushes. Aedeagal tube short and plump with pair of prominent, ventrolateral, spinous tuberosities; dorsal aedeagal sclerite hastate ( Fig. 25 View Figs ); sac curved strongly ventrad and about as long as tube; sac armed at midlength with short lateral rows of 3‐4 large, black, cultriform spines ( Figs. 23‐24 View Figs ); apical and basal areas of sac densely armed with patches of fine spines.

Female. Unknown.

Larva. Unknown.

Etymology. The species name is based on the large ventrolateral tuberosities of the aedeagus.

Diagnosis. The aedeagus of this species is somewhat similar to that of P. cornuta Zwick , but the ventrolateral lobes of that species are smaller and lack spines ( Zwick 1982d). In addition, that species has a small lobe on male tergum 8 and the median patch of tergum 9 consists of only a few scattered sensilla. It is also similar to P. flabellare (described above) but differs in several respects outlined in the diagnosis of that species.
