Haplaphalara Uichanco 1912, stat. rev.

Haplaphalara Uichanco, 1912, stat. rev. Haplaphalara Uichanco 1921: 260. Type species: Aphalara dahli Rübsaamen, 1905, by original designation. = Aconopsylla Tuthill and Taylor 1955: 247. Type species: Psylla sterculiae Froggatt 1901, by original designation. Syn. nov. Diagnosis: Adult. Head, in lateral view, deflexed 45–90° from longitudinal axis of body (Fig. 1G); in dorsal view about as wide as or slightly narrower than thorax, moderately transverse. Vertex rhomboidal; covered in areolate-rugose or imbricate microsculpture, sometimes much reduced on disc; passing smoothly into genae anteriorly; coronal suture fully developed; genaeweaklyproducedventrallybutnotenlargedintoprocesses; frons widely trapezoidal; median ocellus visible or hidden in perpendicular view to vertex; compound eyes, in dorsal view, hemispherical, adpressed to head. Clypeus pear-shaped, medium- to large-sized, flattened ventrally, not or hardly visible in lateral view as it is hidden by genae. Antenna 10-segmented, distinctly longer than head width; flagellum with simple setae; segment 3 longest, longer than segment 4 and shorter than 4–6 together; segments 4, 6, 8, and 9 bearing each a subapical rhinarium lacking marginal spines. Thorax moderately slender; dorsal outline, in lateral view, weakly curved. Pronotum, in dorsal view, weakly curved posteriad laterally; propleurites subrectangular, divided by oblique suture into larger epimeron and smaller episternum. Metapostnotum with blunt tubercle or shallow longitudinal ridge. Mesosternum narrower than head, forming transverse band more than three times as wide as long laterally; anterior margin weakly concave; pleurosternal suture not or hardly visible; basisternum indistinct, but large, oval in H. irvingiae and H. Laos; katepisternum small antero-laterally, not bent dorsad laterally; angle between arms of precoxale obtuse. Pro- and mesotibiae cylindrical. Metacoxa with blunt or subacute horn-shaped meracanthus. Metafemur with the three ventral sense organs in medial or submedial position (Fig. 6I, J); apex with a group of stout long setae. Metatibia longer than metafemur, hardly to distinctly widened apically; bearing 6–10 evenly spaced to distinctly grouped apical sclerotized spurs that may be on raised processes, without unsclerotized bristle-like setae (Fig. 7G). Both metatarsal segments relatively short, subequal in length. Forewing oblong-oval, widest in the middle or in apical third; 2.2–2.4 times as long as wide, membranous; vein C + Sc weakly, evenly convex, slender, distinctly delimited from cell; costal break developed, close apex of vein R 1; pterostigma wide, entirely membranous; nodal line developed in some species; vein R as long as or shorter than M + Cu; vein Rs weakly or moderately convex relative to costal margin; vein M longer than M 1 + 2; vein Cu 1a curved towards anal margin; veins M 1 + 2 and M 3 + 4 perpendicular to wing margin apically; anal break adjacent to apex of vein Cu 1b; surface spinules fine or coarse, spaced or dense, present in all cells or sometimes almost completely lacking. Hindwing slightly shorter than forewing; with one or two costal setae proximal to costal break and two distinct groups one to four proximal and two to five distal setae, distal to costal break; vein R + M + Cu indistinctly trifurcating, base of vein Cu indistinct. Abdominal base usually with a sclerotized area on either side covered in spines. Aedeagus with proximal portion simple or subdivided subapically; apex of distal portion differentiated from stem, though sometimes indistinctly (Fig. 9E). Female subgenital plate with or without apical process. Last instar immature. Antenna nine segments; bearing sectasetae or lanceolate setae on antennal flagellum. Mid- and hindlegs without massive peg-like setae. Dorsal body surface bearing minute clavate setae. Precaudal abdominal tergites lacking densely spaced simple setae or sectasetae. Anus in terminal position; with additional pore fields developed. Comments: In all analyses, Haplaphalara as redefined here is an artificial, paraphyletic assemblage (Figs 10, 11; Supporting Information, File S4). It is morphologically similar to Diclidophlebia and Melanastera from which it differs in the ungrouped apical metatibial spurs and the apex of the metatibia lacking unsclerotized antero-apical bristle-like setae. Except for the strong support in the molecular analyses for H. irvingiae + H. Laos as sister-taxa, there are no consistently supported groupings warranting generic rank within this assemblage. We, therefore, keep it as an artificial, paraphyletic genus awaiting further analyses. Included species, distribution, and host plants are summarized in Table 3 and Supporting Information, File S3.
