Anthelephila tryznai sp. nov.

( Figs. 77–81 , 106 )

Type locality. India, Meghalaya state, 3 km east of Tura, 25°30′N, 90°14′E, 1150 m a.s.l.

Type material. HOLOTYPE: J, ‘NE INDIA, Meghalaya, 2002 3 km E TURA, 1150 m 25°30′N 90°14′E, 6.–12.v. M. Trýzna & P. Benda lgt.’ ( NMPC).

Description (male, holotype). Body length 3.7 mm. Reddish to reddish brown; elytra moderately darkened in apical third.

Head 1.2 times as long as wide, somewhat produced postero-medially but clearly differentiated from short neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes rather large and convex. Dorsal surface moderately glossy, rather coarsely punctate; dorsal punctures somewhat umbiliform, becoming finer and sparser near base. Setation short, subdecumbent, with scattered moderately long, erect setae. Antennae at most moderately enlarged in terminal third; antennomere X 1.3 times and antennomere XI 2.1 times as long as wide.

Pronotum 1.4 times as long as wide, distinctly narrower than head across eyes, nearly evenly rounded anteriorly, strongly narrowed and distinctly impressed and constricted postero-laterally in dorsal view; pronotal disc with moderate median longitudinal impression/groove in anterior half, its outline convex in anterior half and with distinctly protruding bulge posteriorly in lateral view. Dorsal surface largely rather finely but distinctly punctate, with numerous densely spaced, coarse punctures before posterior bulge (nearly transversely rugose at this place), smooth, impunctate and glossy between bulge and base; antero-lateral sides finely and sparsely punctate, impunctate near procoxal cavities; postero-lateral impression coarsely wrinkled and adjacent basal area coarsely punctate and rugose. Setation as that on head.

Mesosternum and metasternum simple.

Elytra 1.7 times as long as wide, conjointly rounded apically; humeri and postscutellar impression rather distinct. Surface glossy, distinctly punctate; punctures simple, unevenly spaced, forming dense transverse band in postcutellar impression, sparsely scattered in basal fourth before band and more densely spaced on the rest of surface. Setation diversified, mostly pale, subdecumbent, with scattered longer erect setae, additionally with short appressed whitish setae forming conspicuous transverse setose band in basal third.

Metathoracic wings fully developed.

Fore legs modified ( Fig. 77 ); profemora with small protuberance on inner side; protibiae simple; penultimate tarsomere widened and flattened distally, with terminal tarsomere articulated dorsally in all tarsi. Setation normally developed.

Abdominal characters as in Figs. 78–81 ; tergum VII simple, evenly rounded apically; apical portion of tegmen 0.6 times as long as basal piece, trilobed apically.

Differential diagnosis. Anthelephila tryznai sp. nov. belongs to the A. praetor species-group ( KEJVAL 1999), showing overall similarity with the sympatric A. gardneri saudeki . Externally, the latter species differs by the form of profemoral process (short but more robust, its outer margin fringed by short stiff setae) and the modification of protibiae (distinctly dilated on inner side behind midlength). It also displays numerous detailed differences in the morphology and setation of male sternite VIII; see Figs. 43 and 46 in KEJVAL (1999).

Etymology. Dedicated to Miloš Trýzna (Děčín, Czech Republic), traveller and well-known specialist in the Anthribidae .

Distribution. India (Meghalaya).

Remarks. The holotype of Anthelephila tryznai sp. nov. originates from the same sample as the 15 specimens of A. gardneri saudeki listed above. Showing no substantial differences, the nine females of this sample were rather tentatively attributed to the latter species. Some of them could in fact belong to the very similar A. comes sp. nov. as well.
