Indonemoura malickyi sp. n.

( Fig. 38-41 )

Material examined. Holotype ♂ and 1♂ paratype from Thailand, Chiang Mai Province, Doi Inthanon National Park , CP3TF, LF, 1600 m, 98° 31’ N, 18° 31’ E, 25 March 1993, H. Malicky ( PMSL). Additional Paratypes: Thailand: Chiang Mai Province, Doi Inthanon National Park , W. Gastehaus, 1600 m, 98° 30’ N, 18° 32’ E, 25 February 1987, 2♂ ( PMSL) .

Adult habitus. General color brown to dark brown. Head and wings dark brown; quadrate pronotum pale brown with obscure rugosities. Palpi brown, antennae uniformly dark brown. Legs pale brown but distal half of hind femora darker; tibiae uniformly pale brown, tarsi darker.

Male. Forewing length 9.5 mm. Epiproct long, broad and widest near apex; projecting tip divided in dorsal aspect ( Fig. 38 ); ventrolateral aspect bearing a subapical spiny lobe ( Fig. 39 ). Mesal lobe of paraprocts long, slender and sclerotized, tip acute in lateral aspect but appearing blunt, or truncate caudally or dorsally ( Figs. 40-41 ); outer lobe reaching beyond midlength of mesal lobe and terminating in a long, slender, acute point. Tergum 10 bearing a few short sensilla adjacent to epiproct tip; tergum nine with patches of sensilla clustered along posterior margin near midlength. Vesicle short and widest at apex ( Fig. 40 ); hypoproct short, wide and bearing a few short, thick setae.

Female. Unknown.

Larva. Unknown.

Etymology. The patronym honors Dr. H. Malicky for his numerous contributions of interesting specimens from southeast Asia.

Diagnosis. Several species share the prominent, spiny ventral epiproct lobe with this species (including I. horvati among regional congeners) and several also have long, heavily sclerotized paraproct lobes. This species lacks the small projections found on tergum 10 in I. horvati and related species, and the long, slightly bifurcate mesal paraproct lobe ( Fig. 41 ) of I. malickyi appears to be distinctive.
