Labasiella tucumanensis OPITZ nov.sp. ( Figs 9 View Figs 1-27 , 36 View Figs 28-43 , 70 View Fig 70 , 88 View Figs 81-89 , 104)

Holotype: ♂. ARGENTINA, TUCUMAN, Horco Molle, XII-1968 ( IMLA). Paratype: 1 specimen. Argentina : Provincia de Salta, 4 km S Campo Quijano , 9-II-1982, H. &. A. Howden ( CMNC).

Diagnosis: The holotype is similar in elytral coloration to the holotype of L. lata , from which it differs by the composition of the antenna. The combined length of the funicular antennomeres is proportionally shorter in the male of L. tucumanensis , than in the female of L. lata (compare Figs 4, 9 View Figs 1-27 ). Also, the pronotum of L. tucumanensis has a deep depression along the midline of the disc.

Description: Size: Length 4.0 mm; width 1.7 mm. Form: As in Fig. 88 View Figs 81-89 . Integument: Cranium and thorax dark castaneous; antennae and mouthparts testaceous, except mandibles brown; legs mostly testaceous, femora with brown annula at distal limit, basal half of tibiae brown; elytra bicolored, black basal margin and black basal half of epipleural margin contiguous with black narrow angular fascia, two small black streaks near basal margin, a broad black angular fascia behind elytral middle, remainder of elytral testaceous. Head: Cranium coarsely punctate, antennal funicular antennomeres subfiliform ( Fig. 9 View Figs 1-27 ), capitulum lax, antennomeres 9 and 10 triangular, antennomere 11 ovate; eyes small, frons wide (EW/FW 10/35); last maxillary and labial palpomere subsecuriform. Thorax: Pronotum ( Fig. 36 View Figs 28-43 ) with angular tubercle at sides, disc coarsely punctate, deeply depressed at middle near anterior pronotal margin, with 6 small knobs; elytral asetiferous punctures arranged into 10 punctiform striae, punctures binodal, punctures extend to elytral apex, epipleural margin serrulate near elytral apex. Abdomen: Aedeagus ( Fig. 104 View Figs 103-107 ) short, distal region of phallobase slightly lobed, tegmen very reduced, submembranous, phallobasic struts confluent with phallobasic apodeme, phallobasic rod long; phallic plates broad, phallic apex broad triangular.

Distribution ( Fig. 70 View Fig 70 ): This species is known from Argentina.

Etymology: The trivial name, tucumanensis, is a Latinized version of the type locality.
