  • Pseudogeniates cordobaensis Soula 2009[1]: 122.

Material examined

Holotype male, from Ohaus’s type series of Pseudogeniates intermedius, at ZMHB labeled: a) “Argentina S. d. Cordoba J. Hubrich S.” (typeset, white label), b) male symbol, c) “Pseudogeniates intermedius cotype Ohs.” (Ohaus’s handwritten, red label), d) “SYNTYPUS Pseudogeniates intermedius Ohaus, 1914 labelled by MNHUS 2007” (typeset, red label), f) “Paralectotype 2009 Pseudogeniates intermedius Oh. Soula det.” (typeset and handwritten, red label), g) “Holotype 2009 Pseudogeniates cordobaensis Soula Soula” (handwritten and typeset, red label). Soula (2009)[1] based the description on one male specimen.

Description

(based on 10 males and 17 females). Length 13.8-17.0 mm. Widest width 6.8-8.0 mm. Color: Dorsum, venter, and appendages rufous-castaneous (Fig. 1). Head (Fig. 16): Frons densely punctate to confluently punctate (mid-disc), rugopunctate laterally and apically; punctures small and moderately large, mixed. Clypeus with dorsal surface densely punctate to confluently punctate (mid-disc), rugopunctate laterally and apically, punctures small and large (mixed), some setose; setae short to moderate, rufous, sparse; shape broadly semicircular, apex and sides broadly reflexed, with or without constriction basolaterally; disc (frontal view) densely rugopunctate, punctures small and large, mixed, some setose (setae short to moderately long, rufous, sparse). Labrum setose; setae moderately long and short, rufous. Maxilla (Fig. 5) with galea distinct, with 1 elongate, bristle-like, medial seta. Mentum (Fig. 8) nearly as long as wide or slightly longer than wide, form pentagonal, inner apex projects anteriorly, with inner shelf. Antenna 10-segmented with 3 segmented club; club slightly longer than stem. Pronotum: Medial line obsolete. Surface (disc and mediolaterally) moderately densely imbricate with sparse, short, testaceous setae. Margin with short, rufous setae. Elytra: Sutural stria impressed from base of scutellum to apex. Elytral apex weakly spiniform or quadrate. Discal striae weakly impressed, 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, stria 5 faintly impressed and incomplete; humeral striae 1-4 faintly impressed, incomplete, indicated by shallow punctures, stria 5 moderately impressed, extending from base of metacoxa to subapex; small to moderate in size, some longitudinal (Fig. 5). Intervals with moderately dense, random punctures, punctures minute to moderate in size; interval 1 broader than others. Pygidium: Disc and apex sparsely punctate; base and sides moderately densely imbricate, nearly obsolete; punctures minute to small. Legs: Protarsomere 5 of male subequal to tarsomeres 2-4. Modified proclaw of male subequal in length to tarsomeres 2-4; internoapical tooth present. Protibia (Fig. 11) (male and female) with teeth evenly separated; basal 1/3 weakly dilated (male) or moderately dilated (female). Mesotibia (male) with sides subparallel, weakly divergent towards apex (male) or weakly divergent (female); apex oblique with 10-11 moderately long spinulae; external edge with weak carina in basal 1/3, 1 carina in apical 1/3. Metatrochanter (male) weakly produced beyond posterior border of femur. Metacoxal corner square (female). Metacoxa at middle weakly produced posteriorly. Metatibia of male (Fig. 14) with sides subparallel, weakly divergent towards apex; external edge with 1 carina in basal 1/3 (faint), 1 carina in apical 1/3 (faint); apex without corbel, with 2 inner spurs (spurs equal in width in male, weakly curved at apex), inner apex with 28 short, stout spinulae. Metatibia of female 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 with sides converging to a quadrate apex (Fig. 19).

Diagnosis

Pseudogeniates cordobaensis is separated from other species in the genus by the pentagonal form of the mentum (width subequal to length) that has the inner apex projecting anteriorly and has an inner shelf (Fig. 8). In comparison, the form of mentum is longer than wide in Pseudogeniates intermedius and Pseudogeniates richterianus (Figs 9-10). In Pseudogeniates intermedius, the inner apex of the mentum does not project anteriorly, but does possess an inner shelf (Fig. 9); in Pseudogeniates richterianus, the inner apex projects anteriorly, but does not possess an inner shelf (Fig. 10). The ventral plate of the male parameres in Pseudogeniates cordob-aensis is nearly as long as dorsal plate with sides converging to a quadrate apex (Fig. 19). The ventral plate of Pseudogeniates richterianus is about half the length of the dorsal plate (Fig. 21), whereas in Pseudogeniates intermedius the ventral plate is nearly as long as the dorsal plate, but the sides converge with a weak constriction preapically and a rounded apex (Fig. 20).

Distribution

(Fig. 22). Pseudogeniates cordobaensis is distributed in the Monte de Sierras y Bolsones in the Monte eco-region in Argentina. The distribution of this species coincides with the Montane Forest region (Navarro et al. 2009[2]) and the Yungas Forest area of endemism in Argentina (Szumik et al. 2012[3]).

Locality data

27 specimens from IAZA, WSUC, and ZMHB. ARGENTINA (27): CATAMARCA (26): Salar de Pipanaco, Pío Brizuela (37 km S Andalgalá, 27°49'34"S, 66°14'47"W, 751 m), Quirós (2 km S on RN 157, 28°48'43.3"S, 65°06'22.6"W), CÓRDOBA (1): Huerta Grande (Sierra de Córdoba).

Temporal data

December (9).

Remarks

The holotype specimen for this species was part of the type series for Pseudogeniates intermedius, a series that included three specimens from Santiago del Estero and one specimen (=Pseudogeniates cordobaensis) from Huerta Grande in the Sierra de Cordóba, Córdoba Province (Ohaus 1914[4]).

Natural history

This species is attracted to black lights. It was recorded from an elevation of 751 m.
