Polyplectropus daimong , new species

Figures 28–30

Diagnosis: This species has almost rectangular quadratic gonopods, each with a very long and downwardcurving dorsoapical filiform process. No other species in this genus have similarly shaped gonopods.

Description: Male. Body uniformly brown. Maxillary palp formula (I,II)-IV-III-V, 3rd segment of each maxillary palp originating subapically on lateral face of segment 2. Forewing length 7.5 mm. Forewings each with closed discoidal cell and open median cell. Forewings each with apical forks 1, 2, 3, 4, and 5; hind wings each with apical forks 2 and 5.

Male genitalia. Sternite IX subtriangular ( Fig. 28 ), with rounded lobe on each posterior margin near its gonopod; tergite IX sclerotized, narrow, parallel-sided and obliquely directed in continuation of sternite IX, meeting on each side at fulcrum with cerci and paraproctal complex. Segment X nearly membranous, locatred anterodorsally of segment IX, apparently fused with tergite VIII, covered with microtrichia; in dorsal view forming narrowing half-tube-like, short, apical roof above phallic apparatus. Cerci elongate, clavate, longer than median process of paraproctal subphallic sclerite. Paraproctal complexes fused to cerci; each paraproctal complex with dorsal process weakly sclerotized, spine-like, horizontally straight, with short apical spine. Subphallic sclerite modified into short basal plate and long, mesal, rod-like process with setose apex. Gonopods almost rectangular, each with long, filiform, dorsoapical ventrad-curving spine-like process ( Fig. 28 ); mesal surface with 2 finger-like processes and rounded lobe below them ( Fig. 29 ). Phallic apparatus ( Fig. 30 ) located dorsally, nearly undiscernible, consisting of tube-like sclerotized phallotheca and membranous endotheca, without visible sclerites inside.

Holotype male: VIETNAM: Lamdong , Baoloc, Baco stream, 26.x.1988, light [J. Oláh]—( OPC).

Paratype: same data as holotype, except Baoloc, Duchma stream, 23.x.1988, light [J. Oláh]— 1 male ( OPC) .

Distribution: Vietnam.

Etymology: Daimong, after Vietnamese ”dai”, long; and “mong”, thin, referring to the gonopods having a long and slender dorsoapical process.
