Panghoella, VIRAKTAMATH & WEBB & YESHWANTH, 2025

Panghoella gen. nov.

Type species: Banus maculosus Distant , here designated.

Diagnosis. Coloration similar to Banus . Male pygofer with dorsal process arising from dorsal margin where it articulates with segment IX, directed ventrally (absent in P. nera sp. nov.). Subgenital plate with only narrow hair-like setae marginally and short thin setae on ventral surface. Style without subapical lobe. Aedeagus with shaft cylindrical, symmetrical, with one pair of processes arising at base of atrium ventrally and articulated with shaft.

Description. Brownish ochraceous with pale and brown markings on head, pronotum, and mesonotum.

Medium sized leafhoppers measuring 3.5–6.1 mm long. Head wider than or narrower than pronotum. Crown surface with apical half shagreen, posterior half polished; median sulcus about 0.75 as long as crown; fore margin rounded to face. Eyes large, their outer margin in line with outer margin of crown, obliquely extending over anterolateral angles of pronotum. Ocelli prominent placed a distance equal to own diameter away from eyes. Antennae long, reaching almost half length of body. Face including eyes about as wide as long; frontoclypeus somewhat narrow; clypellus broad apically. Pronotum slightly convex dorsally, about 1.6–1.9× as long as crown; with lateral margins carinate, surface polished, punctate, posterior margin almost straight. Exposed mesonotum about as long as or distinctly longer than pronotum. Forewing with claval veins separate, inner claval vein connected to claval suture by cross vein, three anteapical and four apical cells, inner anteapical cell open behind, appendix narrow not extending beyond middle of second apical cell. Pro-tibia comparatively long and slender compared to meso-tibia; AV row of setae 15–16, conical, short peg-like, in basal 0.66; AM row of setae represented by hair-like AM1, IC row of setae 14–15, slender hair-like. Metafemur with 2+2+1 apical macrosetae Meta tibia with PD row macrosetae long, as long or longer than half length of fore tibia. Metabasitarsomere with 3 platellae and one stout tapered seta on either side.

Male genitalia. Pygofer with or without anterior apodemes, tergum short, lobes well produced posteriorly, making tergum deeply U-shaped in dorsal view, with numerous macrosetae, in distal half and row of marginal setae, ventral margin convex, posterodorsal angle subconically rounded dorsal processes (absent in P. nera sp. nov.) arising from midlength of pygofer dorsal margin and directed ventrally. Valve with posterior margin angularly produced medially. Subgenital plates triangular, elongate, about 2.5–3.0× as long as basal width, with marginal row of narrow setae in distal 0.66 and narrow short setae on ventral surface or with submarginal row of macrosetae in distal 0.75 region and numerous hair-like setae in distal half. Style without subapical lobe, apophysis pointed and curved near apex, surface transversely corrugated. Connective with stem distinctly shorter than arms. Aedeagus symmetrical, with well-developed dorsal apodeme, shaft slightly curved, apex not produced beyond gonopore; gonopore apical; a pair of articulated basal processes arising from ventral part of atrium. Female valvulae as in the genus Banus and Mavromoustaca .

Etymology. The generic name is an arbitrary combination of letters, gender feminine.

Remarks. This genus closely externally resembles Monobazus and Mavromoustaca in coloration and structure, but differs in the male genitalia: pygofer with dorsal process (ventral processes in other mentioned genera), style with subapical lobe absent (prominently developed in other genera), aedeagus with articulated pair of ventral processes arising from base of atrium and articulated with it (lateroventral basal processes in Mavromoustaca fused with shaft; ventral processes arising from shaft and fused with it in Monobazus ). Panghoella also resembles Chandibanus gen. nov. in having a dorsal marginal pygofer process in the male, but they differ in having the processes directed posteriorly in Chandibanus and ventrally in Panghoella and the aedeagus in the former lacks basal atrial processes.

Based on their male genitalia, two species described in Osbornellus from China belong to this genus, i.e., Panghoella conoidea (Xing & Li in Li et al. 2011: 157, figs 5–147 1–7; Dmitriev et al. 2024: 276) comb. nov. and P. suiyongensis (Xing & Li in Li et al. 2011: 157–158, figs 5–148 1–7; Dmitriev et al. 2024: 276) comb. nov.
