Gustafsson, Daniel R. & Bush, Sarah E., 2014, Two new species of Paraphilopterus Mey, 2004 (Phthiraptera: Ischnocera: Philopteridae) from New Guinean bowerbirds (Passeriformes: Ptilonorhynchidae) and satinbirds (Passeriformes: Cnemophilidae), Zootaxa 3873 (2), pp. 155-164 : 160-163

Paraphilopterus meyi Gustafsson & Bush , new species

( Figs 5–8 , 10 , 13 )

Type host: Cnemophilus macgregorii macgregorii De Vis, 1890 (Cnemophilidae) —crested satinbird.

Other host: Cnemophilus macgregorii sanguineus Iredale, 1948 .

Diagnosis. Similar to P. knutieae , but separated by the lack of a sublateral gap in the pteronotal row of setae and the shape of the dorsal anterior plate, and by the configuration of the male genitalia ( Figs 2 , 6 ). Abdominal chaetotaxy overlaps between the two species, and is not diagnostic. Paraphilopterus meyi is separated from P. styloideus by the same characters as it is from P. knutieae , (see above), except for the male genitalia.

Description. Head shape and chaetotaxy as in Fig. 5 . Similar to P. k n ut i e a e, but with the following differences: head smaller; dorsal anterior plate of different shape ( Fig. 13 ); postocular setae clearly posterior to eye, not near posterior margin of eye; gular plate broadly rhombic, with angular lateral margins.

Thoracic and abdominal segments as in Figs 7–8 . Pronotal post-spiracular setae (PPSS) do not reach posterior margin of pronotum. Most specimens (7 of 10 males and 13 of 19 females) with no PSMS; 3 males and 5 females with one PSMS; one female with one PSMS on each side. Pteronotum with 18–22 setae on posterior margin in males, and 19–25 (one with 17, one with 18) setae in females. Second and fourth setae from lateral margin typically longer than other setae.

Male. Abdominal chaetotaxy as in Fig. 7 . Tergocentral setae: segment II: 12–14 (+ 2 in anterior end); III–V: 10–11; VI–VII: 9–10; VIII: 8–10; IX+X: 2; XI: 4. Sternal setae: II: 6–8; III: 7–8; IV: 3–6; V–VI: 5–8; VII–VIII: 2; IX+X: 0; XI: 4. Pleural setae: II–III: 0; IV: 2–3; V: 3; VI–VIII: 4; IX+X: 3 (one pair very short); XI: 0. Genitalia as in Fig. 6 . Median thickening of mesomere not as clearly defined as in P. knutieae , and not visible in many specimens.

Female. Abdominal chaetotaxy as in Fig. 8 . Tergocentral setae: segment II: 12–15 (+ 2 in anterior end); III: 12–14; IV–VII: 11–14; VIII: 8–11; IX+X: 2; XI: 0. Sternal setae: II: 5–7; III: 4–6; IV–V: 2–4; VI–VII: 3–4. Pleural setae: II–III: 0; IV–V: 2–3; VI: 4; VI–VIII: 3; IX+X: 3 (one pair very short); XI: 4. Pseudostyli each with two setae distally, and one seta basally. Terminalia as in Fig. 10 .
