Plectrocnemia kamba , new species

Figures 18–20

Diagnosis: This species is most similar to P. aietes from Nepal. It is separated by the nearly triangular sternite IX with concave posterior margins (not quadrangular and convex posteriorly); the small paraprocts are anteriorly simple in dorsal view (not bilobed); the gonopods are clearly tripartite in lateral view; and the dorsoapical lobe of each gonopod has 2 prominent megasetae that are lacking in P. aietes .

Description: Male. Body uniformly brown. Maxillary palp formula (I,II)-IV-III-V, 3rd segment of each maxillary palp inserted subapically on subapicolateral face of 2 nd segment. Forewings brown, length 6.3 mm. Discoidal cell closed in each forewing and hind wing; forewings each with median cell closed. Forewings each with apical forks 1, 2, 3, 4, and 5; hind wings each with apical forks 1, 2, and 5.

Male genitalia. Sternite IX nearly triangular, with concave posterior margin on each side in lateral view ( Fig. 18 ); dorsoapical part connecting sternite to fulcrum formed by sclerotized cerci and small paraproctal complex, and meeting points of nearly indistinguishable membranous tergite IX and segment X; tergite IX consisting of small membranous or very weakly sclerotized triangle anterodorsal of fulcrum. Segment X forming small, almost-indiscernible, membranous, triangular roof, visible through and behind cercus in lateral view ( Fig. 18 ). Setose cerci large, foliaceous. Small paraproctal complexes fused to basomesal regions of cerci, each highly reduced and visible as small digitiform process with single terminal seta below cercus in lateral view; anterior corner simple in dorsal view. Gonopods short, trilobed ( Fig. 18 ), basal dorsomesal lobe present terminally, present as inner, elongate, clavate process in central position in lateral view; dorsoapical lobe armed with 2 megasetae; blunt ventroapical lobe covered terminally by numerous short, heavily sclerotized, black tooth-like spines. Phallic apparatus ( Fig. 20 ) broad horizontally, partly supported by weakly discernible membranous subphallic bridge of paraprocts; large sclerotized phallotheca with vertically-directed phallobase with wide anteroventral foramen; border between phallicata and endophallus indistinct; pair of dorsolateral, stout paramers originating from endotheca and each with spiral pattern on apical 1/3rd, visible as sequence of oblique notches or grooves at low magnification and encircling setae at high magnification. Elongate, weakly pigmented phallotremal sclerite in central position inside endotheca.

Holotype male: MYANMAR: NE, Kambaiti 7000 ft, 25.v.1934 [R. Malaise]—( BMNH, Coll. Malaise, B.M. 1938-258).

Paratypes: Same data as holotype, except 17.v.1934 — 2 males ( OPC); same data as holotype, except 2000 m, 21.v.1934 [R. Malaise]— 4 males ( BMNH, Coll. Malaise, B.M. 1938-258) .

Distribution: Myanmar.

Etymology: Kamba, derived from the name of the type locality.
