Diagnosis
Guimaraesiella brunneomarginata sp. nov. is most similar to Guimaraesiella cucphuongensis (Najer & Sychra in Najer et al., 2012), with which it shares the following characters: aps absent on male tergopleurite IV, but present on male tergopleurite V ( Fig. 8 View Figs 8–9 ); female abdominal segment IV with 1 ps on each side ( Fig. 9 View Figs 8–9 ); female abdominal segment V with 2 ps on each side ( Fig. 9 View Figs 8–9 ).
These two species can be separated by the following characters: male tergopleurite VIII with 1 tps on each side in Gu. cucphuongensis , but with 2 tps on each side in Gu. brunneomarginata sp. nov. ( Fig. 8 View Figs 8–9 ); male abdominal segment IV with 2 ps on each side in Gu. cucphuongensis , but with only 1 ps on each side in Gu. brunneomarginata sp. nov. ( Fig. 8 View Figs 8–9 ); female vulval margin with at least 12 thorn-like vss in total in Gu. brunneomarginata sp. nov. ( Fig. 14 View Figs 10–14 ), but with at most 11 thorn-like vss in total in Gu. cucphuongensis .
Etymology
The species name is derived from the Latin ‘ brunneus ’ for ‘brown’ and ‘ margo ’ for ‘edge’, referring to the pigmentation patterns of the abdomen.

Description
Both sexes
Head irregularly pentagonal ( Fig. 10 View Figs 10–14 ), lateral margins of preantennal head clearly convex proximally, but concave in anterior third, frons shallowly concave. Marginal carina broad, narrowing only near anterior end, median margin shallowly irregular. Dorsal anterior plate with shallowly concave anterior margin and convex lateral margins. Ventral anterior plate crescent shaped. Dorsal preantennal suture reaches lateral margins of head, dsms and ads, and in some specimens extend medianly to ads. Preantennal nodi extended medianly. Head chaetotaxy as in Fig. 10 View Figs 10–14 . Coni sharp, reaching to or slightly beyond distal margin of scape. Temples rounded. Temporal marginal carina narrow, widening anteriorly. Thoracic and abdominal segments as in Figs 8–9 View Figs 8–9 . Pigmentation differs between material from the two host subspecies. Material from Pycnonotus goiavier samarensis: base pigmentation of head pale brown, base pigmentation of thorax and abdomen translucent; head nodi, marginal and marginal temporal carinae, gular plate, proepimera, metepisterna, and lateral sections of tergopleurites dark brown. Material from Py. g. personatus: base pigmentation of all body pale yellow brown, not darker on head; head nodi, marginal and temporal marginal carinae, gular plate, proepimera, and metepisterna medium-brown; sternal and subgenital plates pale brown, darker in female than in male; lateral sections of tergopleurites dark brown.
Male
Thoracic and abdominal chaetotaxy as in Fig. 8 View Figs 8–9 . Basal apodeme rectangular with rounded anterior end, widening anteriorly ( Fig. 11 View Figs 10–14 ), not or only slightly constricted at mid-length. Proximal mesosome broad ( Fig. 13 View Figs 10–14 ), roughly trapezoidal, with slightly concave anterior margin and convex lateral margins, constricted in distal end. Ventral sclerite short, not thickened anteriorly, and not approaching anterior margin of proximal mesosome. Mesosomal lobes broad, gently rounded; 3 ames sensilla on each side; 2 pmes microsetae on lateral margins of mesosome. Gonopore broad, distal margin deeply concave. Parameral heads as in Fig. 12 View Figs 10–14 . Parameral blades slender, extended slightly in distal end; pst1–2 as in Fig. 12 View Figs 10–14 . Measurements as in Table 1 View Table 1 .
Female
Thoracic and abdominal chaetotaxy as in Fig. 9 View Figs 8–9 . Subgenital plate with wide lateral submarginal extensions ( Fig. 14 View Figs 10–14 ), lateral ends of these extensions bent posteriorly. Vulval margin gently rounded with straight central part, with 3–4 short, slender vms and 6–8 short, thorn-like vss one each side; 4–7 short, slender vos on each side of subgenital plate; distal 1–2 vos median to vss. Measurements as in Table 1 View Table 1 .
Remarks
Material from the two host subspecies differs in pigmentation patterns (see above). The male from Pycnonotus goiavier personatus has a shorter head than males from Py. g. samarensis, but the male genitalia are indistinguishable between material from the two host subspecies. We here treat all material as conspecific.
