Diagnosis

Brueelia (Painjunirmus) alba sp. nov. is most similar to Br. (P.) chilchil , and Br. (P.) magnini , with which it shares the following characters: aps absent from male tergopleurite III ( Figs 1 View Figs 1–2 , 25 View Figs 25–26 , 33 View Figs 33–34 ) and proximal mesosome slender and more or less rectangular ( Figs 6 View Figs 3–8 , 30 View Figs 27–32 , 38 View Figs 35–40 ).

Brueelia (Painjunirmus) alba sp. nov. is separated from Br. (P.) chilchil on the following characters: sternal plates not modified laterally in Br. (P.) alba ( Figs 25–26 View Figs 25–26 ), but modified in Br. (P.) chilchil ( Figs 1–2 View Figs 1–2 ); lateral margins of mesosome distally convergent in Br. (P.) alba ( Fig. 30 View Figs 27–32 ), but near-parallel in Br. (P.) chilchil ( Fig. 6 View Figs 3–8 ); parameres much more slender in Br. (P.) alba ( Fig. 31 View Figs 27–32 ) than in Br. (P.) chilchil ( Fig. 7 View Figs 3–8 ); basal apodeme slender in Br. (P.) alba ( Fig. 29 View Figs 27–32 ), but broader in Br. (P.) chilchil ( Fig. 5 View Figs 3–8 ); vulval margin gently rounded in Br. (P.) alba ( Fig. 32 View Figs 27–32 ), but with median bulge in Br. (P.) chilchil ( Fig. 8 View Figs 3–8 ).

Brueelia (Painjunirmus) alba sp. nov. is separated from Br. (P.) magnini on the following characters: male abdominal segments III–V with 3 ps on each side in Br. (P.) alba ( Fig. 25 View Figs 25–26 ), but 2 ps on each side in Br. (P.) magnini ( Fig. 33 View Figs 33–34 ); proximal mesosome smaller in Br. (P.) alba ( Fig. 30 View Figs 27–32 ) than in Br. (P.) magnini ( Fig. 38 View Figs 35–40 ); female subgenital plate roughly quadratic in Br. (P.) alba ( Fig. 32 View Figs 27–32 ), but more trapezoidal in Br. (P.) magnini ( Fig. 40 View Figs 35–40 ).

Etymology

The species epithet is derived from the Latin ‘ alba ’ for ‘white ’, referring to the near-complete lack of pigmentation in this species.

Description

Both sexes

Head convex dome-shaped ( Fig. 27 View Figs 27–32 ), lateral margins of preantennal area slightly convex, frons shallowly concave. Marginal carina deeply displaced and much widened at osculum, lateral sections slender with slightly irregular median margins. Ventral anterior plate not visible. Head chaetotaxy as in Fig. 27 View Figs 27–32 . Extent of head pigmentation as delimited by thin dotted line in Fig. 27 View Figs 27–32 , interior of preantennal nodi unpigmented. Thoracic and abdominal segments as in Figs 25–26 View Figs 25–26 ; proepimera with light brown pigmentation; metepisterna, metasternum, and anterior and posterior sections of sternal plates with very faint brown pigmentation.

Male

Scape as in Fig. 27 View Figs 27–32 . Distal abdomen destroyed during mounting of single examined male, and not illustrated. Thoracic and abdominal chaetotaxy as in Fig. 25 View Figs 25–26 ; aps absent from tergopleurite III; tps present on tergopleurites VI–VII; 3 ps on each side of segments III–V and VII, 2 ps on each side of segment VI. Sternal plates without lateral extensions. Subgenital plate with very pale brown pigmentation in anterior end, distal end missing in specimen. Basal apodeme long and slender ( Fig. 29 View Figs 27–32 ). Proximal mesosome short, roughly rectangular ( Fig. 30 View Figs 27–32 ). Lateral margins of mesosomal lobes convergent distally, antero-lateral horns short, more or less straight. Rugose area of distal mesosome extensive; pmes as in Fig. 30 View Figs 27–32 . Gonopore small, distal margin deeply concave; ames as in Fig. 30 View Figs 27–32 . Parameres slender, much elongated; pst1–2 as in Fig. 31. View Figs 27–32

MEASUREMENTS (n = 1). HL = 0.36; HW = 0.31; PRW = 0.20; PTW = 0.33; AW = 0.49.

Female

Scape as in Fig. 28 View Figs 27–32 . Thoracic and abdominal chaetotaxy as in Fig. 26 View Figs 25–26 ; segment II with 2 ps on each side, segments III–VIII with 3 ps on each side. Sternal plates without lateral extensions. Subgenital plate with very faint brown pigmentation in anterior end, but posterior limit of pigmentation diffuse and not illustrated; plate moderately broad, with broad connection to cross-piece ( Fig. 32 View Figs 27–32 ). Vulval margin gently rounded to slightly flattened medianly ( Fig. 32 View Figs 27–32 ), with 3 short, slender vms and 3–5 short, thorn-like vss on each side; 4 short, slender vos on each side of subgenital plate; distal 1 vos median to vss.

MEASUREMENTS (n = 3). TL = 1.80–2.01; HL = 0.41; HW = 0.34–0.36; PRW = 0.21–0.22; PTW = 0.34– 0.36; AW = 0.56–0.60.

Remarks

The occurrence of two different species of Brueelia (Painjunirmus) on Turdoides striata in different parts of its range may indicate that these species are geographically limited. No detailed collection locality is given on the type slides, and more collections are needed to establish whether Br. (P.) alba sp. nov. is more widely distributed.
