Sochinsogonia multimacula, Feng & Dietrich & Zhang, 2018

Feng, Ling, Dietrich, Christopher H. & Zhang, Yalin, 2018, Two new species of Sochinsogonia (Hemiptera: Cicadellidae: Cicadellinae) from Philippines, Zootaxa 4486 (3), pp. 340-348 : 341

Sochinsogonia multimacula sp. nov.

( Figs 1A–L )

Coloration. Crown, prothorax and scutellum, face, thorax, legs and abdomen reddish brown to yellowish-brown, with large irregular round dark brown spot anterad of scutellar suture bearing two small yellowish-brown spots in middle. Forewing brown with extensive irregular orange markings in basal two thirds; hind wing light brown.

Head. Median length of crown about ½ interocular width; transition from crown to face without indentations; ocelli behind interocular line of anterior eye angles, each equidistant from adjacent anterior eye angle and median line of crown; crown distinctly concave between ocelli; antennal ledges slightly protuberant. Clypeal muscle impressions distinct; anteclypeus with median longitudinal arched structure, forming slightly angulate convex around midlength from lateral view, with finely pubescent near apex.

Thorax. From dorsal view, pronotal width much greater than transocular width of head, lateral margins evenly divergent posteriorly; disk sparsely punctate medially. Forewing coriaceous in basal two thirds with indistinct apical membrane; four apical cells well delimited; base of fourth cell distad of third; first tarsomere longer than combined length of the second and third.

Male genitalia. Male pygofer narrow with process arising from base of ventral margin and attaining midventral margin, posterior margin narrowly rounded. Both anterior and posteroventral region disperse a small number of macrosetae. Plates extend posteriorly as far as pygofer apex, with multiseriate macrosetae near middle and sparsely distributing microsetae around anterior region. Connective Y - shaped, well sclerotized. Style slender, extending much farther than apex of connective, with apex curved ventrad and truncate. Aedeagus directed posterodorsally, shaft compressed, with pair of basal processes extended along sides of shaft sinuately curved with short dorsal branch arising near midlength and extended posterodorsad to shaft margin, apex hooked ventrad, without denticuli, in ventral view extended slightly laterad and slightly exceeding shaft apex. Female unknown.

Measurement. Length of male 12.1-12.5 mm.

Material examined. Holotype ♂ ( INHS), Philippines, Bukidnon, Intavas, Mt Kitanglad , August 2011, coll. A. Mohagan ; Paratype: 1♂ ( NWAFU), same data as holotype .

Remarks. This species will run to S. consimilis Young and S. davisi Young in Young's (1986) key to species of the genus. Those two species also occur in the Philippines. The male genitalia of all three are similar but the new species differs in its smaller size and in having the ventral pygofer process larger, the aedeagal process rounded rather than angulate posterodorsally, the style lacking a pair of apical setae, and the forewings with a distinct marmorated pattern of bright orange and dark brown pigment. S. consimilis and S. davisi both have the forewing uniformly olive green in the basal two thirds and the latter also has the subgenital plate distinctly shorter than pygofer.

Etymology. This new specific epithet is a Latin word “ multimacula ” referring to forewing with multiple irregular maculae.
