Description
Description (based on 2 males and 1 female). Length 14.0-15.7 mm. Widest width 7.5-9.0 mm. Color: Dorsum, venter, and appendages rufotestaceous to castaneous (Fig. 2). Head (Fig. 17): Frons densely, confluently punctate or rugopunctate; punctures small and moderately large, mixed. Clypeus with dorsal surface densely punctate, confluently punctate or rugopunctate, punctures small and large, mixed; clypeal shape broadly semicircular, apex and sides broadly reflexed, with or without constriction basolaterally; disc (frontal view) with surface densely rugopunctate, punctures small and large, mixed, some setose (setae short to moderately long, rufous, sparse). Labrum with setae moderately long and short, rufous. Maxilla with galea fused, with 1 or 2 elongate bristle-like, medial, setae. Mentum (Fig. 9) longer than wide, form subtrapezoidal (base broader than apex), inner apex not projecting anteriorly, with inner shelf. Antenna 10-segmented with 3 segmented club; club subequal to stem. Pronotum: Medial line obsolete (male) or weakly indicated (female). Surface (disc) moderately densely imbricate with sparse, short, testaceous setae; surface (mediolaterally) moderately densely rugopunctate, punctures minute and small. Margin with setae short, testaceous. Elytra: Elytral apex rounded or quadrate (not spiniform). Discal striae punctate; 5 on disc mesad of humerus, 5 laterad of humerus; discal stria 1 (adjacent to sutural stria) extending from base to apical umbone; striae 2-3 and 4-5 paired, extending from near base to apical umbone; humeral stria 1 incomplete (extending from mid-elytron to near apical umbone), stria 2 extending from humerus to near apical umbone, striae 3-4 extending from base of metacoxa to near apical umbone (indicated by punctures, not sulcate), stria 5 poorly indicated, extending from base of metacoxa to subapex (indicated by punctures near base, sulcate near apex); punctures small, some longitudinal. Intervals with moderately dense, random punctures, some transversely wrinkled (on disc), punctures small; interval 1 broader than others. Pygidium: Disc and apex moderately densely punctate, some transverse; base and sides closely, weakly rugulose; punctures minute to small. Legs: Protarsomere 5 of male subequal to tarsomeres 2-4. Modified foreclaw of male subequal in length to tarsomeres 2-4; internoapical tooth present. Protibia (male and female) with external teeth evenly separated; basal 1/3 weakly dilated (male) or moderately dilated (female) (e.g., Figs 11-13). Mesotibia (male) with sides subparallel, weakly divergent towards apex; apex oblique with 8-11 moderately long spinulae; external edge with weak carina in basal 1/3, 1 carina in apical 1/3. Metatrochanter (male and female) weakly produced beyond posterior border of femur. Metacoxal corner square (female). Metacoxa at middle weakly produced posteriorly. Metatibia (male) with sides subparallel, apex weakly divergent; external edge with 1 carina in basal 1/3, 1 carina in apical 1/3; apex without corbel, with 2 inner spurs (spurs equal in width in male, with a weak curve at apex), inner apex with 21-25 short, stout spinulae. Metatibia (female) greatly divergent at apical 1/5; external edge with 1 carina in basal 1/3, 1 carina in apical 1/3; apex without corbel, with 2 inner spurs, inner apex with 28 short, stout spinulae. Parameres: Ventral plate nearly as long as dorsal plate but the sides converge with a weak constriction preapically and a rounded apex (Fig. 20).
Diagnosis
Diagnosis. Pseudogeniates intermedius is known from only three specimens. It is separated from other species in the genus by the form of the mentum (Fig. 9) and the form of the male parameres (Fig. 20). It is distinguished from Pseudogeniates cordobaensis by the form of the mentum (longer than wide and subtrapezoidal in Pseudogeniates intermedius [Fig. 9]; length subequal to width and pentagonal in Pseudogeniates cordobaensis [Fig. 8]) and apex of the ventral plate of the male parameres (with a weak constriction preapically and a rounded apex in Pseudogeniates intermedius [Fig. 20]; lacking preapical constriction and with quadrate apex in Pseudogeniates cordobaensis [Fig. 19]). It is separated from Pseudogeniates richterianus by the apex of the mentum (with an inner shelf in Pseudogeniates intermedius; lacking inner shelf in Pseudogeniates richterianus [Fig. 9 versus Fig. 10]) and length of the ventral plate of the male parameres (nearly as long as dorsal plate in Pseudogeniates intermedius [Fig. 20]; half length of dorsal plate in Pseudogeniates richterianus [Fig. 21]).
Distribution
Distribution (Fig. 22). Pseudogeniates intermedius is distributed in the Chaco-seco eco-region in Argentina.
