Diagnosis

Guimaraesiella lorica sp. nov. is most similar to Guimaraesiella caligogularis sp. nov., with which it shares the following characters: male tergopleurites IV–V without aps, but tergopleurite VI with aps ( Figs 22 View Figs 22–23 , 36 View Figs 36–37 ); male abdominal segment VI with 3 ps on each side ( Figs 22 View Figs 22–23 , 36 View Figs 36–37 ); proximal mesosome trapezoidal, constricted distally ( Figs 27 View Figs 24–28 , 41 View Figs 38–42 ); female abdominal segment IV with 1 ps on each side and segment V with 2 ps on each side ( Figs 23 View Figs 22–23 , 37 View Figs 36–37 ).

These two species can be separated by the following characters: dorsal preantennal suture does not reach lateral margin of head in Gu. lorica sp. nov. ( Fig. 24 View Figs 24–28 ) but reaches lateral margin of head in Gu. caligogularis sp. nov. ( Fig. 38 View Figs 38–42 ); male abdominal segment V with 1 ps on each side in Gu. caligogularis sp. nov. ( Fig. 36 View Figs 36–37 ), but with 2 ps on each side in Gu. lorica sp. nov. ( Fig. 22 View Figs 22–23 ); proximal mesosome more constricted distally in Gu. lorica sp. nov. ( Fig. 27 View Figs 24–28 ) than in Gu. caligogularis sp. nov. ( Fig. 41 View Figs 38–42 ); distal mesosome more broadly rounded in Gu. caligogularis sp. nov. ( Fig. 41 View Figs 38–42 ) than in Gu. lorica sp. nov. ( Fig. 27 View Figs 24–28 ); ventral sclerite slender with thickening in proximal end in Gu. lorica sp. nov. ( Fig. 27 View Figs 24–28 ), but generally massive without such thickening in Gu. caligogularis sp. nov. ( Fig. 41 View Figs 38–42 ).

Etymology

The species name is derived from the Latin ‘ loricus ’ for ‘corselet’, referring to the distinct narrowing of the mesosome.

Description

Both sexes

Head pentagonal ( Fig. 24 View Figs 24–28 ), lateral margins of preantennal head straight to slightly convex, frons concave. Marginal carina moderate, narrowing slightly anteriorly, with shallowly undulating median margins. Dorsal anterior plate with shallowly concave anterior margin and slightly convex lateral margins. Ventral anterior plate roughly triangular, but with deeply concave anterior margin. Narrow dorsal preantennal suture does not reach ads in 2 examined males, and reaches ads on only one side in 2 examined females; in 2 males and 1 female suture reaches ads; suture does not reach lateral margins of head. Preantennal nodi moderate, not extended medianly. Head chaetotaxy as in Fig. 24 View Figs 24–28 . Coni do not reach distal margin of scapes. Temples rounded, temporal marginal carina slender, of more or less constant thickness. Thoracic and abdominal segments as in Figs 22–23 View Figs 22–23 . Base color pale brown yellow, darkening to pale brown on marginal carina, head nodi, gular plate, proepimera, and metepisterna, and to medium brown on lateral section of tergopleurites.

Male

Thoracic and abdominal chaetotaxy as in Fig. 22 View Figs 22–23 . Basal apodeme broad ( Fig. 25 View Figs 24–28 ), constricted at midlength. Proximal mesosome trapezoidal ( Fig. 27 View Figs 24–28 ). Ventral sclerite short, with thickened anterior end. Mesosomal lobes bulging slightly in anterior end, slender distally; 3 ames sensilla on each side; 2 pmes microsetae on lateral margins of mesosome. Gonopore deeply crescent shaped. Parameral heads as in Fig. 26 View Figs 24–28 . Parameral blades stocky, narrowing only near distal end; pst1–2 as in Fig. 26 View Figs 24–28 . Measurements as in Table 1 View Table 1 .

Female

Thoracic and abdominal chaetotaxy as in Fig. 23 View Figs 22–23 . Subgenital plate broad ( Fig. 28 View Figs 24–28 ), with slender, somewhat diffuse, lateral submarginal extensions that reach slightly more than halfway to lateral ends of vulval margin. Vulval margin gently rounded ( Fig. 28 View Figs 24–28 ), with 3 short, slender vms and 6–7 short, thornlike vss on each side; 4–6 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. Measurements as in Table 1 View Table 1 .
