Pseudoneureclipsis quancong , new species

Figs 85–92

This small, brown animal from Vietnam is similar to P. boquan , new species. It is easily separated from P. boquan in having the terminal part of segment X less-developed, membranous; the sclerotized basal part of segment X is less discernible; the median digitiform process on segment X is short; the preanal appendages are armed with only 2 long processes; and the harpagones and the quadrangular basolateral flanks of the coxopodites are shorter.

Male. Head tentorium H-shaped in dorsal view, with long, slender posterior arms; tentorial bridge slender, anteriorly with small, mesal, triangular projection; anterior tentorial arms each with large, mesoventral lamella. Entire labrum hanging freely. Mandibles extremely large, broad; surface granulate papillose. Haustellum broad, granulate, without channels on most of dorsum; channels present at base along sitophore. Tubercles located along posterior end of coronal groove, between occipital compact setal warts; rather pale, membranous, like dome or cupola organs; sensillae campaniformia or sensillae placodea with slightly morepigmented, central rounded area. Forewing length 4.0 mm; fork I as large as fork III.

Male genitalia. Segment IX with narrow tergite and well-developed, compact sternite; tergite reduced to antecostal ridge articulating with narrow dorsolateral rods of sternite IX; lateral rod of tergite IX directed ventrad, slightly broadening into small, flank-like plate at point of articulation. Segment X produced into digitate, setose, papillate, sclerotized dorsal lobe and membranous hood over phallic apparatus; anterior basal part of membranous hood well-developed, hinged laterally to fulcra in caudal view; basal sclerotized and setose lobe of segment X with long, median process and 4–5 small, irregular digits on either side of median process; process and digits ending in terminal setae and additional buds, protuberances or setose tubercles. Pair of paraproctal processes (intermediate appendages) hinged to bases of preanal appendages; producing pair of broad, straight rods directed posterad, each armed with strong terminal spine-like seta. Basic plan of preanal appendages similar to basal part of segment X; 2 long, filiform processes with strong terminal spinelike setae present: dorsal process almost straight, directed slightly dorsad; ventral process sinuous, directed posterad. Inferior appendages with coxopodites large, broad, nearly triangular in lateral and ventral views; each with basolateral flank nearly rectangular in lateral view. Harpagones located basodorsally, forming robust, posterad-curving, setose spine-like process. Intersegmental membrane of each inferior appendage (articulation line between coxopodites and harpago) well developed. Phallic apparatus narrowing distally; curving dorsad before apex; 2 less-pigmented terminal processes embedded in membranous apex. Endotheca densely covered by microtrichia of 2 sizes; terminal microtrichia small; microtrichia before terminal area long.

Holotype male: VIETNAM: Tamdao, 200 m, 12.x.1986, at light [J. Oláh], (OPC). Paratype: Same data as holotype, 1 male.

Etymology. Quancong , from Vietnamese “ quancong ,” arms, referring to the 2 pairs of processes on the preanal appendages and 1 pair of paraproct processes, each having a large and strong terminal seta, like 6 lances.
