Polana (Varpulana) recurva

sp. nov.

Polana (Varpulana) recurva sp. nov.

( Figs 45–66 View FIGURES 45–57 View FIGURES 58–66 , 71, 72 View FIGURES 67–72 )

Diagnosis. Style ( Fig. 55 View FIGURES 45–57 ) with apical portion of blade recurved. Aedeagus ( Figs 56, 57 View FIGURES 45–57 ) with apodemal processes filiform; shaft with pair of processes near base and without subapical processes.

Measurements (mm). Holotype male: total length 6.2. Paratypes (male), 6.1−6.3; (female), 6.9−7.0.

Description. A s in description of the subgenus.

Coloration. Head and thorax ( Figs 45 View FIGURES 45–57 , 71, 72 View FIGURES 67–72 ) brown. Crown ( Fig. 45 View FIGURES 45–57 ) with two small rounded black spots behind ocelli, near posterior margin. Pronotum ( Fig. 45 View FIGURES 45–57 ) with eight black maculae near anterior margin. Face ( Fig. 46 View FIGURES 45–57 ) without maculae. Proepimeron ( Fig. 47 View FIGURES 45–57 ), with a black strip below pronotal carina. Forewing ( Fig. 48 View FIGURES 45–57 ) brown with black markings on cross veins of discal cell and apex of anal veins; with transverse dark brown band on apical third, from R1 vein to apex of clavus; apex smoky. Legs light brown.

Male terminalia. Sternite VIII ( Fig. 49 View FIGURES 45–57 ) 1.4 times wider than long; posterior margin broadly rounded, slightly emarginated. Valve ( Fig. 50 View FIGURES 45–57 ) with posterior margin rounded with small median notch. Pygofer ( Fig. 51 View FIGURES 45–57 ) 1.7 times longer times longer than maximum height; dorsal margin with short process at base; apex tapered and slightly excavate; posterior margin ( Fig. 52 View FIGURES 45–57 ), in ventral view, with rounded protrusion near apex. Subgenital plate ( Fig. 53 View FIGURES 45–57 ) 2.5 times longer than wide; tapered toward apex; apex rounded. Connective ( Fig. 54 View FIGURES 45–57 ) linear, with stalk long and wide, 1.5 times longer than arms width. Style ( Fig. 54 View FIGURES 45–57 ), in dorsal view, with outer lobe small and subacute; in lateral view ( Fig. 55 View FIGURES 45–57 ), ventral protrusion short, as wide as long, apex serrated; blade recurved, slightly tapered toward apex; apex curved outward and acute. Aedeagus ( Figs 56, 57 View FIGURES 45–57 ) with apodemal processes filiform and curved dorsally, shorter than shaft length; shaft curved dorsally, wider near base and tapered toward apex, with pair of processes near base and parallel to shaft, shorter than shaft apex, without subapical processes; shaft apex membranous, curved ventrally.

Female terminalia. Sternite VII ( Fig. 58 View FIGURES 58–66 ) 1.6 times wider than long; posterolateral corners rounded; posterior margin slightly excavated laterad of rounded median lobe with small notch medially. First valvifer ( Fig. 60 View FIGURES 58–66 ) 1.9 times higher than long. First valvula ( Fig. 62 View FIGURES 58–66 ) with apex abruptly tapered with dorsal margin irregular. Second valvula ( Fig. 64 View FIGURES 58–66 ) apex with approximately eight small teeth. Other characteristics as in the description of the subgenus.

Etymology. The new species name refers to the apically recurved style.

Material examined. Holotype male: “ Brasil, Paraná, S. [São] J. [José] dos\ Pinhais , 25°36’18”S \ 49°11’37”W 880m \ 01-31.III.2018 Malaise\ A.C. Domahovski leg.”, ( DZUP) GoogleMaps . Paratypes: 1♀, same data as holotype except 01- 30.II.2018, ( DZUP); 2♀, same data as holotype except 01-30.IV.2018, ( DZUP); 1♂, same data as holotype except 05-15.XII.2018 Sweep, ( DZUP); 1♂, same data as holotype except 01-31.XII.2019, ( DZUP) GoogleMaps .

Remarks. Polana (V.) recurva sp. nov. is most similar to P. (V.) pandara in overall coloration ( Fig. 71 View FIGURES 67–72 ) and in having the aedeagus with apodemal processes very thin and the shaft with processes at mid-length, without subapical processes ( Fig. 56 View FIGURES 45–57 ). However, the new species can be easily separated by the smaller size (6.1 to 7.0mm in the new species and 8.2 to 9.3 in P. (V.) pandara ) and the sinuous apical portion of the style ( Fig. 55 View FIGURES 45–57 ), a characteristic not found in the other species of Varpulana.
