TYPE SPECIES. — Tapirissus guilberti n. sp.
ETYMOLOGY. — The generic name is derived from the combination of two other generic names – Tapirus ( Mammalia, Tapiridae ) and Issus (type genus of the family Issidae ) to show the similarity of postclypeal proboscis of the new genus and trunk of Tapirus indicus (Desmarest, 1819) – which is the single Oriental species of the family Tapiridae .
DISTRIBUTION. — Northern Laos.
D IAGNOSIS. — Metope elongate, without sublateral carinae ( Fig. 1C, D View FIG ). Metope and coryphe joined at obtuse angle – metope wholly visible from above ( Fig. 1A View FIG ). Coryphe transverse.Postclypeus large, in shape of flattened laterally proboscis bearing a median carina, resembling a chisel ( Fig. 1B View FIG ). Fore wing with reticulate venation and without hypocostal plate ( Fig. 1B View FIG ). Hind wings one-lobed ( Fig. 2 View FIG ). Hind tibia distally with a single lateral spine.
COMPOSITION. — Monotypical genus.
TAXONOMIC RELATIONSHIPS. — Closely related to the genera Eusudasina Yang, 1994 and Euxaldar Fennah, 1978 .
DESCRIPTION
Metope elongate, enlarged above clypeus, with rows of small bumps (tubercles) along its lateral margins and with weak median carina which runs from its upper margin to its middle; without sublateral carinae ( Fig. 1C, D View FIG ). Metopoclypeal suture almost straight. No ocelli. Coryphe transverse, with keel-shaped margins; anterior margin weakly convex, posterior margin weakly concave ( Fig. 1A View FIG ). Pronotum short, anterior margin obtusely angulate, keel-shaped, posterior margin almost straight; with no carinae. Paradiscal fields very narrow behind the eyes. Paranotal lobes wide, without carinae. Mesonotum longer than pronotum, without carinae. Tegulae small. Fore wings narrowly rounded apically ( Fig. 1B View FIG ), without hypocostal plate, with reticulate venation – longitudinal veins furcate often, with many transverse veins in between including the clavus; all veins are raised. Basal cell large, rounded. Hind wings one-lobed,veins with setae, costal margin deeply concave, anal lobe reduced – hind margin of the wing is formed by first anal vein ( Fig. 2 View FIG [A 1]). First metatarsomere with two latero-apical spines and six intermediate spines. Second metatarsomere with only two latero-apical spines.
