Pseudodira amazona sp. nov.

( Figs 1–3 , 28–32 , 33 )

Type locality. Peru, San Martín Region, Tarapoto.

Type material. HOLOTYPE: ♀, ‘ Amazones, Tarapote, M. de Mathan [collector], 4e Trimestre 1885’ ( MNHN).

Description. Length 7.5 mm; TL/EW = 1.18; PL/PW = 0.44; EL/EW = 1.06; EW/PW = 1.76. Body oval ( Figs 2 , 33 ). Pronotum chestnut brown with anterior angles piceous. Elytra chestnut brown with suture black. Pubescence short, dense, yellow. Punctation dual, shallow, with smaller punctures very fine, dense, larger punctures sparsely distributed.

Head covered with long, dense pubescence. Antennae with 11 antennomeres; scape about 2.3 times as long as pedicel; pedicel about 1.3 times as long as wide; as long as antennomere III. Antennomere III 2.1 times longer than wide, about 2.0 times as long as IV; antennomeres IV and VI subquadrate, antennomere V longer than wide, longer than antennomere IV, antennomeres IV–VI subquadrate; antennomeres VII and VIII transverse. Clypeus not produced.

Prosternal process ( Fig. 1 ) 0.32 times as wide as mesoventral process, elongate, about 1.66 times as long as wide; mesoventral process flat, at median length of coxa 0.86 times as broad as corresponding coxal diameter.

Elytral epipleuron 2.5 times as wide as corresponding metanepisternum ( Fig. 2 ).

Abdominal postcoxal lines incomplete laterally, parallel to posterior margin of ventrite 1 ( Fig. 28 ). Female ventrite 5 weakly arcuate; abdominal sternite VIII weakly emarginate apically ( Fig. 29 ).

Female genitalia ( Figs 30, 32 ) with proctiger (TX) truncate at apex, transverse, about 2.4 times as wide as long; coxites suboval, about 1.9 times as wide as long; styli visible. Bursa copulatrix not divided, simple, spermatheca not observed.

Male unknown.

Differential diagnosis. Pseudodira amazona sp. nov. can be separated from P. clypealis by having antennae with 11 antennomeres, clypeus not produced, and abdominal postcoxal lines not recurved. This species shares with P. carmelitana the abdominal postcoxal lines shape and the presence of styli, but its body size is larger ( P. amazona – 7.5 mm, P. carmelitana – 6.0 mm), oval, with piceous anterior angles of pronotum, black elytral suture, and antennomere V as long as antennomere IV.

Etymology. The name of the new species is an adjective referring to the Amazonian part of the Peru where the holotype was collected.

Distribution. Peru ( Fig. 36 ).
