Notoxus distortus sp. nov.

( Fig. 9 )

Type locality. India, Meghalaya, West Garo Hills, Nokrek National Park, 25°29.6′N 90°19.5′E, about 1100 m a.s.l.

Type material. HOLOTYPE: J, ‘NE-INDIA: Meghalaya W Garo Hills Nokrek NP; ca. 1100 m // 25°29.6′N 90°19.5′E 9.- 17.5.1996 leg. Jendek & Sausa’ ( NHMW).

Description. Male (holotype). Body length 4.9 mm. Head and pronotum reddish brown. Elytra reddish, with slightly darker base and rather distinct brown black markings; subapical spots very vaguely connected along suture with transverse band. Legs and antennae reddish.

Body only moderately glossy, rather densely punctured. Punctation of pronotum and head mostly rather fine, pronotum additionally with some scattered coarse punctures. Punctation in basal half of elytra generally more distinct, coarser than that of head and pronotum. Body setation mostly appressed to subdecumbent; pronotum with some conspicuously long erect setae, especially laterally; elytra with numerous, moderately longer suberect setae. Antebasal setose band of pronotum conspicuous, widely interrupted medially.

Head with conspicuously large eyes. Antennae long, only moderately enlarged in terminal third. Pronotum 1.1 times as wide as head across eyes, globose in dorsal view; transverse sulcus / impression of posterior collar smooth dorsally. Pronotal horn moderately long, slender, largely subparallel, armed with 4–5 distinct lateral lobules on each side and wider, moderately emarginate apical lobule; horn crest only moderately raised, evenly lowering towards horn apex, its lateral margins feebly marked by series of somewhat coarser, distinctly separate lobules / rugules; dorsal surface rather evenly and densely covered by distinct rounded rugules. Elytra 2.1 times as long as wide; humeri distinctly protruding; omoplates and postbasal impression rather distinct; elytral apices indistinctly modified, at most unevenly rounded, with minute, inconspicuous gland opening near slightly angled margin. Protibiae slightly sinuous and moderately angulately produced on inner side close behind mid-length. Abdominal sternum VII simple, widely rounded posteriorly. Tergum VIII forming simple, evenly arched sclerite. Aedeagus as figured ( Fig. 9 ).

Female. Unknown.

Differential diagnosis. Notoxus distortus sp. nov. is undoubtedly very close to N. bellus , as suggested by overall similarity, including male characters. It differs from the latter species only in the detailed morphology of the parameres and the apical portion of the tegmen of the aedeagus.

Etymology. From the Latin word distortus (crinkly, twisted); named in reference to the peculiar morphology of the aedeagus.

Distribution. India: Meghalaya.
