Diagnosis.
Head (Fig. 20A View Figure 20 ) with wide longitudinal dark-brown band between ocelli. Pygofer (Fig. 20G View Figure 20 ) with apex excavated. Subgenital plate (Fig. 20H View Figure 20 ) with long filiform setae. Style (Fig. 20H View Figure 20 ) apex truncate, with dorsal process short and acute. Aedeagus (Fig. 20L, M View Figure 20 ) with ventral margin of apodemal process forming rounded lobe produced ventrally; shaft with pair of apical processes directed ventrally and slightly curved laterally, with 1\4 length of shaft.
Measurements.
Total length: holotype male 7.3 mm; paratypes, males (n = 15) 6.8-7.5 mm, females (n = 6) 7.5-7.7 mm.
Description.
Head, in frontal view (Fig. 20B View Figure 20 ), frons 1.2 × wider than long; frontogenal suture distant from eye margin by approximately half maximum width of clypeus; clypeus 1.2 × wider than long; lateral margins straight, slightly convergent apically; apex straight. Head, in lateral view (Fig. 20C View Figure 20 ), crown-face transition thin, with 3 transverse carinae; clypeus not inflated. Forewing (Fig. 20D View Figure 20 ) with apex of anal veins bifid. Profemur AV row with 5-6 setae; PV row with 1 seta near apex. Protibia PD row with 3 setae and undifferentiated intercalary setae; PV row with 5 setae and undifferentiated intercalary setae. Metatibia PD, AD and AV rows with 22-25, 12 and 13-14 macrosetae respectively. Metatarsomere I 4 × longer than apical width; inner row of the ventral surface with 5 setae. Other characteristics as in generic description.
Coloration.
Head and thorax (Figs 20A-D View Figure 20 , 31G, H View Figure 31 ) yellowish-brown. Head (Fig. 20A View Figure 20 ) with pair of small circular black spots, near posterior margin, behind ocelli; wide longitudinal dark-brown band between ocelli. Face (Fig. 20B View Figure 20 ) yellowish; antennal pit dark brown. Pronotum (Fig. 20A View Figure 20 ) with black punctures; small black maculae near anterior margin, behind eye and ocellus; median portion with wide longitudinal dark-brown band, continuous to the band of head and evanescent toward posterior margin of pronotum; proepimeron (Fig. 20C View Figure 20 ) almost entirely black. Mesonotum (Fig. 20A View Figure 20 ) with brown lateral angles, pair of small median brown spots near scutoscutellar suture. Forewing (Fig. 20D View Figure 20 ) with brown veins, larger dark-brown maculae on apex of anal veins, outer discal cell, costal margin, cross veins of discal and apical cells, transverse brown stripe over subapical cells. Metatibia (Fig. 20C View Figure 20 ) with cucullate bases of setae blacks.

Valve (Fig. 20F View Figure 20 ) 1.8 × wider than long; posterior margin rounded. Pygofer, in lateral view (Fig. 20G View Figure 20 ), 1.7 × longer than maximum height; basodorsal process thin and short, extending ventrally for 1/5 height of lateral lobe; anteroventral margin rounded, posterodorsal and posteroventral margins straight and weakly convergent posterad; apex broad and excavated, forming two rounded tips. Subgenital plate, in lateral view (Fig. 20G View Figure 20 ), not reaching pygofer apex; in ventral view (Fig. 20H View Figure 20 ), elongated, 4 × longer than wide, maximum width near median third; long filiform setae on ventral surface near outer margin and dorsal surface near base; inner margin slightly rounded; outer margin straight; apex tapered, subacute. Connective (Fig. 20I View Figure 20 ) about as wide as long; anterior margin excavated; dorsal keel reduced; stem short. Style, in dorsal view (Fig. 20J View Figure 20 ), with outer lobe developed and rounded; in lateral view (Fig. 20K View Figure 20 ), blade with approximately same width along entire length; apical third slightly curved dorsally, with ventral margin serrated; apex truncate, with dorsal process short and acute. Aedeagus (Fig. 20L, M View Figure 20 ) preatrium weakly developed; dorsal apodeme with dorsal margin straight, lateral margins slightly produced laterally; apodemal processes narrow basally, curved in right angle dorsally in the basal third; ventral margin forming rounded lobe produced ventrally; distal portion straight, apex rounded and curved over the apex of shaft; shaft symmetrical and approximately cylindrical, strongly curved dorsally near base, with small basolateral expansion that surrounds the previous portion of shaft; apex with pair of processes directed ventrally and slightly curved laterally, with 1/4 length of shaft. Other characteristics as in generic description.
Female terminalia.
Sternite VII (Fig. 21A View Figure 21 ) 1.8 × wider than long; posterolateral angles rounded; posterior margin deeply excavated each side of median lobe which occupies the median third and is V-shape notched medially. Internal sternite VIII membranous. Pygofer (Fig. 21A, B View Figure 21 ) 1.8 × longer than maximum height; ventral margin slightly rounded; dorsal margin straight; apex rounded. First valvifer (Fig. 21C View Figure 21 ) triangular, 1.5 × longer than wide; anterior and dorsal margins straight; posterior margin slightly rounded.

Etymology.
The new species name refers to the wide dark-brown band between the ocelli.
Remarks.
Coarctana nigromedia sp. nov. can be distinguished from C. asymmetrica sp. nov. by the style shape (Fig. 20K View Figure 20 ) with apex lacking process on ventral margin and the aedeagal shaft (Fig. 20L, M View Figure 20 ) with pair of apical processes symmetric in length.
