Monobazus himalayensis Distant 1908: 352 View in CoL , fig. 223.

Diagnosis. Crown with prominent dark brown markings enclosing two rows of pale areas ( Figs 4K View FIGURES 4 , 7E View FIGURES 7 ). Male pygofer with hooked process on posterodorsal angle. Subgenital plate with hair-like setae, without macrosetae. Aedeagus with dorsal apodeme short, shaft almost straight, with ventral process arising slightly distad of base and bifid short distance before apex. Female sternite VII longer medially than sternite VI, about 1.3× as wide as long medially, posterior margin produced medially ( Fig. 11G View FIGURES 11 )

Description. Coloration as described by Distant (1908). Male similarly colored as female.

Head distinctly narrower than pronotum. Crown subconically rounded, 0.7× as long as interocular distance. Pronotum 1.9× as wide as long medially. Face including eyes wider than long. Female sternite VII excluding median projection rectangular and 1.7× as wide as long excluding posterior median projection; posterior margin medially produced posteriorly and the projection 0.4× as long as median length ( Fig. 11G View FIGURES 11 ).

Male genitalia. Pygofer more or less triangular, 1.5× as long as wide in lateral view, posterodorsal angle narrowed and hook-like. Subgenital plate 10× as long as wide at base, with long hair-like setae, without macrosetae. Style apophysis broad at base, gradually narrowed and pointed near apex. Connective with stem much shorter than arms. Aedeagus in lateral view Y-shaped, preatrium elongate, dorsal apodeme short, shaft straight, slightly narrowed distally, with one ventral process arising slightly distad of base and forking near apical 0.25, gonopore apical, flanked laterally by extension of shaft.

Female genitalia. Valvula I broad basally and tapering apically, sculpturing more or less concatenate with sculpturing extending to dorsal margin and occupying distal 0.6 length ( Figs 13 View FIGURES 13 EF). Valvula II slightly convex in mid region making it sinuate, with basal hyaline area well developed, toothed area occupying distal 0.5 length, teeth small and spaced widely in proximal region and much close to each other apically ( Figs 13 View FIGURES 13 GH).

Measurements. Male 6.1 mm long, 1.4 mm wide across eyes and 1.5 mm wide across posterolateral angles of pronotum.

Material examined. INDIA: West Bengal: SYNTYPE 1♀, Kurseong, N.E. Himalayas, Annandale ( BMNH) . Other material. India : West Bengal: 1♂, Kalimpong, 1370m, 29.x.1981. S. Viraktamath ( UASB) .

Remarks. This species was described from an unspecified number of specimens (syntypic) with the following data: “N. E. Himalayas; Kurseong (Annandale)”. It is very similar to Longicornus grandis (Pruthi) (see below) in size and coloration of the crown, but details of the markings on the crown and the forewing are quite different.Also, they have significantly different male genitalia (see Remarks under L. grandis ).
