Pseudoneureclipsis boquan , new species

Figs 53–56

This species is similar to P. quancong , new species, and P. u s i a Malicky & Chantaramongkol, 1993, from Thailand from which it is separated by the presence of a more discernible sclerotized basal part of segment X and more developed membranous terminal part of segment X; a longer median finger-like process on segment X, not short; preanal appendages armed with 3 long processes instead of 2 processes in P. quancong and 4 + 3 processes in P. u s i a; and the harpagones and the quadrangular basolateral flanks of the coxopodites are longer than those of P. quancong and the harpagones are more slender and the basolateral flanks of the coxopodites are more developed than those of P. u s i a.

Male. Tentorium H-shaped in dorsal view, with long and slender posterior arms; tentorial bridge slender, with small mesal triangular projection; anterior tentorial arms with large mesoventrad-oriented lamella. Entire labrum freely hanging. Haustellum forming broad, granulate plate without channels on most of dorsum, channels present at base along sitophore. Epistomal sutures connecting pits not observed. Forewing length 4.0 mm.

Male genitalia. Segment IX with narrow tergite and well-developed compact sternite, tergite reduced to antecostal ridge articulating to narrow dorsal rod of sternite IX in hinge-joints; narrow lateral rod of tergite IX directed ventrad; slightly broadening into small flank-like plate at articulation. Segment X produced into setose and papillate sclerotized dorsal lobe, and into membranous hood over phallic apparatus; anterobasal part of membranous hood well-developed, discernible in caudal view and hinged laterally to fulcra; dorsobasal sclerotized and setose lobe of segment X composed of long median finger and small, irregular protrusions on each side of finger, each with 4–5 digits in dorsal view; finger and digits ending in terminal setae and additional buds, protuberances or setose tubercles. Pair of paraproctal processes (intermediate appendages) hinged to base of preanal appendages, forming pair of straight, broad rods directed posterad, each armed with strong terminal, spine-like, seta. Basic structural plan of preanal appendages similar to multidigitate basal part of segment X, except each with 3 long, filiform processes each with strong terminal spine-like seta: dorsal process almost straight, directed slightly dorsad; 2 ventral processes sinuous, directed posterad. Coxopodites large, broad, sub-triangular in lateral and ventral views, each with basolateral flank nearly rectangular, large, occupying basal half of coxopodite in lateral view, well visible in ventral view; harpagones positioned basidorsally, each forming long, slender, posterad-curving, setose spine-like process; intersegmental membrane of each inferior appendage (articulation line between coxopodites and harpago) visible. Phallic apparatus narrowing and turning dorsad toward apex, with 2 terminal, less pigmented processes embedded into membranous apex; endotheca densely covered by small terminal microtrichia and long sub-terminal microtrichia.

Holotype male: VIETNAM: Hoabinh, towards Dabac, 21.x.1986, at light [J. Oláh], (OPC).

Etymology. Boquan , from Vietnamese “ boquan ,” meaning army, referring to the 3 processes on each preanal appendage and 1 process on each paraproct, each armed with a large and strong terminal seta, like 8 lances.
