Xue, Qingquan, Mckamey, Stuart H. & Zhang, Yalin, 2017, Philippogalla, a new genus for Philipposcopus modestus (Baker) from the Philippines, and a new species of Philipposcopus (Hemiptera: Cicadellidae: Idiocerinae) from China, Zootaxa 4291 (1) : -

Philippogalla gen. n.

Type species: Pedioscopus modestus Baker, 1915: 331 .

Body small. Crown short, wider than pronotum. Head and pronotum shagreen ( Fig. 1 C). Face slightly wider than long; lateral frontal suture present, curved, not reaching ocelli; ocelli closer to eyes than to each other; antenna not expanded apically or subapically; frontoclypeus and anteclypeus broad; base of anteclypeus wider than apex, lateral margin concave; rostrum reaching hind coxae, apex not expanded; lorum moderately wide; lateral margin of gena convex ( Fig. 1 D). Pronotum finely punctate, each pit surrounded by pale colour, lateral margin short, elevated and convex. Combined length of mesoscutum and scutellum as long as pronotum and crown together. Forewing with 4 apical and 2 subapical cells, both subapical cells open, outer apical cell very large; appendix broad, extending to the middle of 3rd apical cell; clavus with 2 veins ( Fig. 1 E). Fore femur with short and fine AD and PD setae; AV and PV with few long and fine setae. Fore tibia with dense long and stout AV and PV setae on distal half, fine and long setae on basal half. Hind tibia with 10–12 setae on row PD, 6 setae on AD and 8–9 setae on row AV. Hind femur with 2+1 apical setae. First tarsomere with three platellar setae.

Male pygofer dorsal margin with large apodeme; distal half of ventral area with numerous dense small submarginal tubercles and row of short marginal spines ( Fig. 3 A). Segment X developed, anteroventral angle fingershaped. Subgenital plate slightly longer than pygofer; with dense long fine setae on dorsal and ventral margin. Style curved dorsally, apex slender, without setae ( Fig. 3 F). Connective with large medial longitudinal keel ( Figs. 3 B–C). Aedeagal shaft short, curved dorsally, tapering distally; lateral area with pair of processes medially, not surpassing apex of aedeagal shaft; dorsal apodeme short; preatrium developed; gonopore apical ( Figs. 3 D–E).

Female genitalia. Seventh sternite caudal margin produced, concave in middle ( Fig. 1 N). First valvulae curved dorsally, with sculpture strigate; second valvulae slender, curved obviously, with a few unaligned dorsal teeth ( Figs. 1 J– M).

Etymology. This feminine generic name is based on the type locality of the type specimens, the Philippines.

Distribution. Philippines.

Remarks. The new genus resembles Philipposcopus Maldonado-Capriles , but differs in having a small body, the lateral frontal suture short (not reaching ocelli), and the ventral area of the pygofer with dense short stout processes on its distal half. The new genus seems to have close affinities with Angusticella Maldonado-Capriles based on the similar shape of the aedeagus and style, but it can be distinguished from the latter genus by the forewing with the 3rd apical cell quadrate and the pygofer with dense nodule-like processes on the posterior area.
