Description
Female. Habitus as in Fig. 5 and head as in Fig. 11. Anterior setae 3 (as3) rigid, 0.04–0.05 long; anterior dorsal head setae (ads) peg-like, 0.02 long. Hyaline membrane with deep concavity and thick sclerotization of its margin, 0.03–0.04 long; anterior margin of the anterior dorsal plate deeply concave and ventral head plate more concave than the dorsal one (Fig. 34). Pterothorax with 8 posteromarginal setae on each side. Tergo-pleural plate II with a reduced postero-lateral projection overlapping segment III, tergo-pleural plate III without any projection. Tergocentral setae: II, 12–13 (plus 2 anterior setae); III, 15–16; IV, 13–18; V, 16–19; VI, 16–17; VII, 12–14; VIII, 6–12. Tergites VII–IX+X as in Fig. 21. Sternal setae (intraspecific variation in parentheses): II, SL-SL (plus 1–2 long setae laterad to sternal plate); III, LL-SLL (LSL-SLL); IV, LLSLL-LLSLL (LLSLL-LSLLL); V, LLSLL-LLSLL (LLSLL-LSLLL); VI, LLLL-LLLL (LLLLL-LLLL). Segments IV-VII with 1–4 long additional setae situated on soft tegument, between the sternal plate and the pleural setae. Paratergal setae (all long): II–III, 0; IV–V, 3; VI, 4 (rarely 3 on one side only); VII, 3–4; VIII, 1–2. Segments VI–VIII with an innermost dorsal seta on each tergite (included in the paratergal count), besides the postspiracular seta. Sternites III–VI with well-developed, large plates, roughly rectangular. Vulva with 7–9 medium long setae each side, and 4–6 small setae on the middle of the vulvar margin. Subgenital plate, inner genital sclerite, subvulval sclerites, and vulvar margin as in Fig. 22.

Male. Similar to female, except in dimensions and morphology of terminalia (Fig. 6). Pterothorax with 7–9 posteromarginal setae on each side. Tergocentral setae: II, 11–14 (plus 2 anterior setae); III, 10–18; IV, 10–17; V, 9–19; VI, 10–18; VII, 11–13; VIII, 7–8. Tergites VII–IX+X as in Fig. 23. Paratergal setae (all long): II–III, 0; IV–V, 2–4; VI–VII, 3–4; VIII, 2. Sternal plates well developed and entire on segments III–VI; subgenital plate with 4 proximal long setae and 2 distal postero-lateral long setae (Fig. 24). Genitalia: length of parameres 0.50 (Fig. 35).

Etymology
The s pecies epithet is a noun in apposition derived from the species name of the host, and also refers to the dark colour of the lice.
Remarks
Morphologically close to Philopteroides macrocephalus by having: anterior dorsal head setae (ads) peg-like; segment III without pleural setae; segment IV with 2 pleural setae; sternite VI without spine-like setae; setae of the male subgenital plate situated on the plate. However, both sexes of Philopteroides fuliginosus can be distinguished from those of Philopteroides macrocephalus by: (1) the hyaline margin with a shallower indentation (0.03–0.04mm) at its midline (compare Figs 11 and 12; 34 and 36); (2) the female tergal chaetotaxy and shape of tergites IX+X (Fig. 21); (3) the male subgenital plate (Fig. 24); and (4) the male genitalia (Fig. 34).
