Polana (Polana) torta, Domahovski, 2025

Polana (Polana) torta sp. nov.

( Figs 1I, J View FIGURE 1 , 9 View FIGURE 9 )

Diagnosis. Style ( Fig. 9J View FIGURE 9 ), in lateral view, blade foot-shaped; ventral margin produced forming a serrated rounded lobe. Aedeagus ( Fig. 9K, L View FIGURE 9 ) with pair of basolateral processes as long as shaft, wider on basal fourth; shaft without processes apex weakly sclerotized and strongly recurved to left side.

Measurements. Holotype male: total length 7.4 mm.

Coloration. Head and thorax ( Figs 1I, J View FIGURE 1 , 8A–D View FIGURE 8 ) yellowish-brown. Crown ( Fig. 9A View FIGURE 9 ) coronal suture black. Face ( Fig. 9B View FIGURE 9 ) without maculae. Pronotum ( Fig. 9A View FIGURE 9 ) without maculae. Proepimeron ( Fig. 9C View FIGURE 9 ) with pronotal carina yellow and a small black spot near posterior angle of eye. Mesonotum ( Fig. 9A View FIGURE 9 ) with pair of small yellow spot on lateral angle. Forewing ( Figs 1I, J View FIGURE 1 , 9D View FIGURE 9 ) yellowish-brown smoky, brown stripe extending from apex of clavus to R1 vein; black markings on base of clavus, cross veins of inner discal cell, apex of A1 and Pcu, and cross veins of apical cells.

Description. Similar to the description of Polana inflexa sp. nov. except:

Head ( Fig. 9B View FIGURE 9 ), in ventral view, clypeus 1.1x longer than wide, lateral margins approximately parallel. First tarsomere not examined (lost).

Male terminalia. Sternite VIII ( Fig. 9E View FIGURE 9 ) rectangular, 1.6x longer than wide; posterior margin straight. Valve ( Fig. 9F View FIGURE 9 ) 2.5x wider than long; integument thickening present only on dorsal margin, posterior margin slightly rounded. Pygofer ( Fig. 9G View FIGURE 9 ) 1.6x longer than high; basodorsal processes without subapical tooth; macrosetae dispersed on dorsoapical quadrant; ventral margin straight; apex rounded. Subgenital plate ( Fig. 9G View FIGURE 9 ) extending to apical third of pygofer; in ventral view ( Fig. 9H View FIGURE 9 ) ovate, outer margin rounded with short setae on apical half; apex rounded. Connective ( Fig. 9I View FIGURE 9 ) Y-shaped, almost extending to apex of style; anteroventral margin with a median protrusion extending anterad; stem wider apically; dorsal keel small. Style ( Fig. 9I View FIGURE 9 ), in dorsal view, outer lobe reduced; in lateral view ( Fig. 9J View FIGURE 9 ) blade foot-shaped; ventral margin produced forming a serrated rounded lobe; apex with small process curved dorsally. Aedeagus ( Fig. 9K, L View FIGURE 9 ) with preatrium short; dorsal apodeme rounded; pair of basolateral processes as long as shaft, wider on basal fourth, apex acute; shaft without processes, uniformly curved; apex weakly sclerotized and strongly recurved to left side.

Female. Unknown.

Etymology. The new species name comes from the Latin word “ tortus ” meaning twisted. It refers to the recurved apical portion of aedeagus.

Material examined. Holotype male, COSTA RICA: “ Costa Rica - Estácion \ Biológica La Sirena - \ PN Corcovado - \ 21m 8º28’48”N \ 83º35’22”W \ 11 a 14/II/2011 \ RR Cavichioli leg.” ( DZUP). GoogleMaps

Remarks. The new species is similar to Polana mala , due to the apically foot-shaped style and the aedeagus lacking processes on the shaft. However, P. torta sp. nov. bears longer subgenital plates and the blade of the style is longer and more robust.
