Diagnosis
. Part of the
Pygatyphella
B complex; very similar to
Pygat.
limbatipennis
, which is not known from
San Cristobal
, distinguished by the median pronotal markings, the paler brown elytra, the slightly paler and much wider lateral elytral margins, and the restricted occurrence on
San Cristobal
.
Male.
8.1–9.8 mm
long;
3.4–3.9 mm
wide; W/L 0.4. Colour (
Fig. 329, 338
): Pronotum orange yellow, semitransparent with underlying fat body visible, and 2 small median dark brown areas; elytra mid-brown, lateral margins widely pale yellow and semitransparent, pale margins extending from outer edge of humerus to apical area of suture; MS and MN pale yellow; head, antennae and palpi very dark brown; venter of thorax pale orange yellow except for very dark brown tarsi and apical ¾ of tibiae; basal ventrites yellowish, V3 with dark markings in one Bweinaniawarikiapu male and two Napagiwae; V4 extensively in representatives from all locations, V4 lightly marked in Bweinaniawarikiapu (3) and Manipwena (2); V5 always very dark brown, V7 yellowish and semitransparent behind LO; basal tergites yellowish, T 4–6 marked irregularly in light brown; T 7 and 8 orange yellow and semitransparent. Pronotum (
Fig. 338
):
1.7–2.3 mm
long; 3.0–
3.7 mm
wide; W/L 1.6–1.7; lateral margins with rounded convergence in posterior areas; lacking indentation near posterolateral corners; with slight irregularities along rounded posterolateral corners, which project at least as far as median posterior margin. Elytron: convex-sided; 6.0–
7.5 mm
long; interstitial lines not well–defined. Head: large, moderately exposed, not able to be completely retracted into prothoracic cavity; GHW
1.9–2.4 mm
; SIW
0.2–0.3 mm
; SIW/GHW 0.1; ASD<ASW, sockets very close but not contiguous; frons not defined. Abdomen, ventrites: LO in V7 occupying half or less than half the area, not reaching sides, posterior margin not emarginated; muscle impressions clearly visible through cuticle in arched, not swollen, posterior half; posterolateral corners of V7 angulate. MPP symmetrical or asymmetrical, squarely or obliquely truncate (slightly obliquely truncate in Wugiroga 1, Bweinaniwarikiapu 1, Manipwena 3, and Napagiwae 1; obliquely truncate in remainder, very strongly in Bweinaniwarikiapu 1 and Kira Kira 1); with a broad dorsal ridge developed slightly to the left of centre. Tergites: T8 outline pattern 4 (
Fig. 440
); as wide as long, with low rounded curved elevation in posterior area to one side of mid-line; lateral margins converge posteriorly and median posterior margin (viewed from above) narrowly rounded; anterolateral prolongations of T8 elongate, narrow, and expanded vertically; ventrally directed pieces at bases of prolongations of T8 present. Aedeagal sheath (
Figs 362, 363
) subparallel-sided for 1/3–1/2 of its length past articulation with sheath tergite, then right side emarginate; anterior margin of tergite not emarginated; tergite with slight projection to R (as in
Figs 360, 361
). Aedeagus (
Figs 370, 371
): L/W <3; LL/ML wide; LL diverge along most of their length dorsally, slightly shorter than ML, apices rounded and subequal in width to ML; ML bearing narrow pointed lateral teeth, apex rounded truncate; base of LL not asymmetrically produced, slightly irregularly rounded.
Female.
9.0–
9.6 mm
long. Coloured as for male with these exceptions: V6 with yellowish LO which is retracted narrowly across the posterior margin which is semitransparent with whitish fat body visible in irregular clumps; V7, 8 semitransparent with underlying fat body confusing the basic colour, V7 with diffuse brown markings in median and anterolateral areas in all but one Bweinaniwarikiapu female. V7 lacking anterolateral depressions; with median posterior margin shallowly emarginate, and posterolateral areas broadly rounded; V8 median posterior margin narrowly emarginate; T8 with lateral margins converging posteriorly and posterior margin rounded.
Larva.
Unknown.
Etymology.
The specific name is a noun formed by combining part of the name of the species it most resembles (
limbatipennis
) and ‘fusca’ (dark) to highlight the dark markings on the pronotum. For a discussion on the possible variability in colour and morphology in specimens of this species,
