Treatment

Pseudophacopteron aulmanni View in CoL sp. nov.

( Figs. 30 View FIGURES 29–38 , 68 View FIGURES 67–76 , 86–88, 174–175, 231, 248)

Description. Adult. Colour. Similar to P. zimmermanni . Fore wing as in Fig. 30 View FIGURES 29–38 .

Morphology. Head and legs similar to P. zimmermanni . Antenna relatively slender, segments cylindrical, weakly widening to apex; terminal setae subequal, the longer terminal seta only slightly longer than segments 9 and 10 together ( Fig. 231 View FIGURES 230–246 ). Fore wing pyriform, apex truncate; surface spinulation present in cells cu 2 and apical portion of r 2 ( Fig. 68 View FIGURES 67–76 ) or similar to P. zimmermanni . Male proctiger, in lateral view, relatively long and narrow (Fig. 86). Paramere relatively short, slender; in lateral view, nearly parallel-sided, apical part narrowly rounded, apex forming a tooth; paramere inner side densely covered with stout setae (Fig. 87). Apical dilation of distal segment of aedeagus relatively narrow, with dorsal margin basally angular and apex regularly rounded; a fine groove present on surface of apical dilation near dorsal margin (Fig. 88). Female proctiger and subgenital plate with short apical extensions; circumanal pore ring with two rows of pores, pores of outer row contiguous; subgenital plate, in lateral view, with ventral margin convex and apex forming a small tooth (Fig. 174); in ventral view subacute (Fig. 175). Dorsal and ventral valvulae laterally with 3–5 distinct teeth (Fig. 174). Measurements and ratios in Tabs. 2–4.

Fifth instar larva ( Fig. 248 View FIGURES 247–250 ). Similar to P. zimmermanni , differing only in longer setae on abdomen. Average length of simple setae on caudal plate margin 0.063 mm (standard deviation 0.020, number of measured setae N=118). Average length of lanceolate setae on dorsum of caudal plate 0.017 mm (standard deviation 0.005, number of measured setae N=203). Other measurements and ratios in Tab. 5.

Host plant. Khaya senegalensis (Meliaceae) .

Biology. Unknown.

Distribution. Nigeria, south-eastern Africa (Zambezi River).

Material examined. Holotype, ♂, NIGERIA: Zaria , Samaru, 11 February 1969, abundant on citrus (J. C. Deeming). Dry-mounted [ BMNH] . Paratypes: NIGERIA: 10 ♂, 6 ♀, same data as holotype ; 2 ♂, 1 ♀, 19 larvae, Zaria, 29 January 1968, Khaya senegalensis (D. L. Krieger) .? MOZAMBIQUE /? ZAMBIA /? ZIMBABWE: 7 ♂, 24 ♀, “Afrika or., Zambesi” (without exact information on locality, date and collector). Dry- and slide-mounted [ BMNH, HNHM, MMBC, NHMB] .

Etymology. Named after the German entomologist Georg Aulmann, author of the first catalogue of world Psylloidea ( Aulmann 1913).

Comments. P. aulmanni is close to P. zimmermanni , sharing a similar size, coloration including the fore wing pattern, morphology of most body parts of both adults and larvae, and the same host plant. It differs from the latter in the shorter antennal terminal setae, the shape of paramere, the narrower apical dilation of the aedeagus, the less convex female subgenital plate, and the longer setae on caudal plate of fifth instar larvae. The male and female terminalia of P. aulmanni are similar to P. fuscivenosum , from which it differs in the fore wing colour pattern, the shape of paramere and the host plant. The fore wing membrane of P. fuscivenosum is infuscated dark brown along veins R, the basal half of M, the entire length of Cu 1b, and the basal half of Cu 1a ( Fig. 31 View FIGURES 29–38 ). The paramere, in lateral view, is slightly broader and has a more convex posterior margin (Fig. 90). See also the comments under P. khayae .
