Molytria vegranda Roth, 1999

Figs 25-35

Material examined: MHNG; 1 male; Australia, New South Wales, Jenolan ; 15-20.I.1995; G. Henrgag. – MHNG; 1 female with same data as for male .

Redescription of male ( Figs 25-35 ): The original description of Roth (1999) can be supplemented with the following details. Head with facial part dark, upper part about above ocelli, vertex and occiput black. Interocular space about as long as width between antennal sockets (~ 1.9 mm); distance between eyes about 0.8 times eye length; distance between antennal sockets about 1.7 of scape length (about 1.1 mm); approximate ratio of lengths of 3rd to 5th segments of maxillary palps 1.1: 1.0: 1.5. Fore tibiae not thickened distally. Anterior margin of fore femora of type B armament, with 5-6 spines, including 1 apical one. Tibial spines well developed. Structure of hind tarsi ( Figs 25-26 ): metatarsus slightly shorter than other segments combined, with large euplantulae occupying about half of metatarsus length, two more or less equal rows of spines located in proximal part of metatarsus; euplantulae of 2nd to 4th segments large; euplantulae of 1st to 3rd segments bordered with 1-2 additional spines ( Figs 25-26 , a.s.); claws symmetrical and simple; arolium about half of claw length. Fore and mid tarsi generally similar to hind tarsi, but segments comparatively shorter; fore tarsi without spines; metatarsus of mid tarsi with short rows of spines. Anal plate as in Fig. 27 . Hypandrium nearly symmetrical ( Figs 28-29 ), with caudal margin rounded, without median incision; styli symmetrical and fusiform.

Genitalia ( Figs 29-35 ). Right phallomere (R+N) with caudal part of sclerite R1T rounded at caudolateral angle ( Figs 30-31 , c.p.R 1T ), densely covered with bristles; R2 distinctly curved; R3 elongated and curved, area between caudal branches sclerotized ( Fig. 30 , scl.a.); R4 platelike; R5 large, fused with sclerite R3. Sclerite L2D (L1) divided into basal ( Fig. 29 , b.L 2D ) and apical parts ( Figs 29-32 ); basal part rod-like, distinctly widened cranially, with two lateral outgrowths caudally ( Fig. 32 ); apical part elongated, densely covered with recumbent bristles; “dorsal outgrows” absent. Sclerite L3 (L2d) with basal subsclerite ( Fig. 33 , b.L 3 ) and “folded structure” ( Fig. 33 , f.s.), bristles weak; apex of L3 with well developed “small tooth” ( Figs 33-35 , s.t.); groove hge absent. Sclerite L4U (L3d) large and transverse ( Fig. 29 ).

Redescription of female: The original description of Roth (1999) can be supplemented with the following details. Head more rounded and eyes and ocelli smaller than in male; distance between eyes about as long as eye length; distance between antennal sockets about 2.2 of scape length (about 1.0 mm); approximate ratio of lengths of 3rd to 5th segments of maxillary palps 1.1: 1.0: 1.4. Structure of legs similar to that of male.

Measurements (in mm): Head length: male 4.2, female 4.6; head width: male 4.0, female 4.5; pronotum length: male 6.3, female 7.1; pronotum width: male 8.2, female 10.3; tegmen length: male 27.0, female 7.5; tegmen width: male 8.5, female 7.2.
