Pseudoneureclipsis bonkybin , new species

Figs 49–52

This small-sized, brown species is most similar to P. philemon Malicky & Prommi (Malicky et al. 2000) from Thailand. In P. bonkybin the sclerotized basal lobe of segment X has 2 longer median setose finger-like processes that are absent in P. philemon ; the lance-like process on each preanal appendage is long and slender, not short and broad; and the coxopodites are longer. The cephalic and thoracic grooves and setal warts follow the general pattern of the genus.

Male. Forewing length 5.0 mm.

Male genitalia. Segment IX with narrow tergite and compact sternite, tergite reduced to antecostal ridge articulating to narrow dorsal rod of sternite IX in hinge; narrow lateral rods of tergite IX directed ventrad, slightly broadening into small, flank-like plate at point of articulation. Segment X produced into multidigitate, setose, papillate, sclerotized dorsal lobe and membranous hood, dorsally covering phallic apparatus; basal sclerotized and setose lobe of segment X forming pair of long, median, finger-like parallel processes and smaller, irregular protrusions, each with 4–5 digits, present on either side of these processes in dorsal view; finger-like processes and digits ending in terminal setae and additional buds, these protuberances or setose tubercles making surface of segment X more complicated. Pair of paraproctal processes (intermediate appendages) hinged to bases of preanal appendages, producing pair of straight, broad rods directed posterad on each side, each armed with strong terminal spine-like seta. Basic structural plan of preanal appendages similar to multidigitate and papillose basal part of segment X, except each also with single, long, filiform process with strong terminal spine-like seta instead of irregular, small digits and tubercles with terminal setae. Coxopodites of inferior appendages forming long rods, each slightly dilated and with dorsad-curving apex. Harpagones located dorsobasally, forming long, mesad-curving rods with clavate apices, each bearing strong spine-like setae on mesal surface of apical half. Each inferior appendage with intersegmental membrane (i.e., articulation line between coxopodite and harpago) well-developed. Phallic apparatus with ventrad-curving bulbous phallobase and broad and straight horizontal phallotheca with transparent, almost hyaline, apical half on venter; endotheca densely covered by 3 types of microtrichia; terminal pair of clusters with large microtrichia visible in ventral and dorsal views; rounded membranous matrix covered with densely packed, minute microtrichiae; protruding endotheca margined anterodorsally and anteroventromesally by mediumsized microtrichia clusters.

Holotype male: VIETNAM: Bac Thai Province, Quang Chu, 24–25.v.1987, at light [J. Oláh], (OPC).

Etymology. Bonkybin , from Vietnamese “ bon ,” 4, and “kybin,” lancer, referring to the pair of processes on the preanal appendages and the pair of processes on the paraprocts, altogether 4 long rods each having a large and strong terminal seta, like 4 lancers.
