Figs 43–44. Guimaraesiella phlaoalopha sp. nov. 43 . Male habitus, dorsal and ventral views. 44 . Female habitus, dorsal and ventral views. These two species can be separated by the following characters: abdominal segment IV with 1 ps on each side in both sexes in Gu. phlaoalopha sp. nov. ( Figs 43–44 ), but with 2 ps on each side in Gu. mayoensis sp. nov. ( Figs 15–16 ); male abdominal segments VI–VII with 3 ps on each side in Gu. mayoensis sp. nov. ( Fig. 14 ), but with only 2 ps on each side in Gu. phlaoalopha sp. nov. ( Fig. 43 ); shape of proximal mesosome and ventral sclerite differs between species ( Figs 20 , 48 ), and sclerite with proximal thickening in Gu. phlaoalopha sp. nov. ( Fig. 48 ) that is absent in Gu. mayoensis sp. nov. ( Fig. 20 ). Etymology The species name is derived from ‘ phlao ’, Greek for ‘to crush’, and ‘ alophos ’, Greek for ‘without a crest’, referring to the host genus name.

Description Both sexes Head pentagonal ( Fig. 45 ), lateral margins of preantennal head slightly convex, frons straight to slightly concave. Marginal carina gradually narrowing anteriorly, with irregular inner margin. Dorsal preantennal suture reaches ads and dsms , but does not reach lateral margin of head. Dorsal anterior plate broad, with deeply concave anterior margin and convex lateral margins. Ventral anterior plate broadly crescent shaped. Preantennal nodi extended medianly. Head chaetotaxy as in Fig. 45 . Coni do not reach distal margin of scapes. Temples rounded. Temporal marginal carina slender, irregular. Thoracic and abdominal segments as in Figs 43–44 . Base pigmentation pale yellow, darkening slightly on marginal carina, gular plate, proepimera, metepisterna, and lateral sections of tergopleurites. Male Thoracic and abdominal chaetotaxy as in Fig. 43 . Basal apodeme widened and rounded anteriorly ( Fig. 46 ), lateral margins straight to slightly constricted at mid-length. Proximal mesosome broad ( Fig. 48 ), narrowing distally, with shallowly concave anterior margin. Ventral sclerite reaching to near proximal margin of mesosome, thickened anteriorly. Mesosomal lobes long but narrow, gently rounded; 3 ames sensilla on each side; 2 pmes microsetae on lateral margins of mesosome. Gonopore widely crescent shaped. Parameral heads as in Fig. 47 . Parameral blades elongated distally; pst1–2 as in Fig. 47 . Measurements as in Table 1 . Female Thoracic and abdominal chaetotaxy as in Fig. 44 . Subgenital plate with wide, irregular lateral submarginal extensions and broad stalk between the main and terminal part ( Fig. 49 ). Vulval margin gently rounded, slightly flattened medianly ( Fig. 49 ), with 3 short, slender vms and 4–6 short, thorn-like vss on each side; 3 short, slender vos on each side of subgenital plate; distal 1 vos median to vss . Measurements as in Table 1 .
