Oláh, János & Johanson, Kjell Arne, 2010, Contributions to the systematics of the genera Dipseudopsis, Hyalopsyche and Pseudoneureclipsis (Trichoptera: Dipseudopsidae), with descriptions of 19 new species from the Oriental Region., Zootaxa 2658, pp. 1-37 : 20-21

Hyalopsyche orissa , new species

Figs 45–48

This species is medium-sized, brown, with well-pigmented, thick veins. The wing venation includes a complete set of apical forks, like in H. sachalinica Martynov , H. similis Martynov and the Australian H. disjuncta Neboiss, 1980 . The species is close to H. plurispinosa Schmid, 1959 , from China (Guangdong), from which it is separated by the different shape of the inferior appendages and the fact that the apex of the phallic apparatus is not bent vertically and has fewer spines.

Male. Head and thoracic characters identical with those of H. trunga , new species (above), except with spur formula 3, 4, 4. Forewing length 5.8 mm; membrane and veins light brown, covered by scarce cinereus setae. Forewing and hind wing venation complete.

Male genitalia. Segment IX with well-developed tergite and sternite; tergite half as long as sternite, long, triangular, narrowing ventrolaterad; sternite quadrangular, with short, narrowing anterodorsal corners; long, narrow tergal and short sternal straps hinged together longitudinally. Segment X relatively large, forming lesspigmented hood over phallus with weakly discernible setose area. Intersegmental depression between segments IX and X well-developed, stepwise in lateral view. Preanal appendages elongate filiform in dorsal and lateral views, with pointed apices. Inferior appendages short, sub-quadrangular in lateral view; elongate in ventral view; mesal surfaces each armed with dorsal row of long spines and ventral patch of short, strong spines; outer lateral surfaces covered by fine setae. Phallic apparatus slender, tubular, consisting of phallotheca and endotheca; tip of endotheca or aedeagus obscurely structured, possible aedeagus visible in dorsoapical trough filled with 9 spines arranged in 2 rows, ventral lobe bearing 2 spines.

Holotype male: INDIA: Orissa State, Bhubaneswar, marsh, ii.1983, at light [J. Oláh], (OPC).

Paratype: Same data as holotype, 1 male (OPC).

Etymology. Orissa , from the Indian state Orissa , the type locality of the species.

Hyalopsyche winkleri (Ulmer) , new combination

Hyalopsychella winkleri Ulmer, 1930: 422 –424, 480, 495, f 66–68.

Hyalopsychella haplotes Neboiss, 1989: 108 , figs 22–25. New Synonym.

Material examined. “O. Borneo, Tangaron 115e” [Mjöberg], 1 male ( SMNH).

Remarks. Neboiss (1989) described H. haplotes from Sulawesi and distinguished it from H. winkleri based on Ulmer’s drawings, rather than actual specimens, because the 3 syntypes of H. winkleri from Borneo were destroyed during World War II and the neotype from Sumatra ( Ulmer 1951) has not been found. The specimen examined has the arrangements of spines on the inner surfaces of the inferior appendages and on the apex of the phallic apparatus identical to those of H. haplotes .
