Treatment

Labasiella robles OPITZ nov.sp. ( Figs 25 View Figs 1-27 , 50 View Figs 44-56 , 71 View Fig 71 , 80 View Figs 72-80 )

Holotype: ♀. CHILE:SaddleCerroRobles,P. Santiago, 6300', XII-24-1967. A second label reads: Collectors: L. & C. W. O̕ Brien ( FSCA).

Diagnosis: Specimens of this species superficially resemble those of L. transversalis , from which they differ by absence of pronotal knobs and by presence of serrations on the posterior 1/3 rd of the epipleural margin.

Description: Size: Length 4.0 mm; width 1.4 mm. Form: As in Fig. 80 View Figs 72-80 . Integument: Mostly testaceous; cranium and pronotum very light castaneous; elytral disc tricolorous, basal 1/3 rd testaceous, then with dark brown triangular patch, followed by broad testaceous transverse fascia, distal 1/3 rd dark brown; abdomen brown. Head: Cranium coarsely punctate, antennal funicular antennomeres subfiliform ( Fig. 25 View Figs 1-27 ), capitulum lax, longer than length of funicular antennomeres, antennomeres 9 and 10 long/triangular, antennomere 11 ovate; eyes small, frons wide (EW/FW 10/35); last maxillary and labial palpomere subsecuriform. Thorax: Pronotum ( Fig. 50 View Figs 44-56 ) with angular tubercle at sides, disc coarsely punctate, without knobs; elytral asetiferous punctation arranged into 11 punctiform striae, punctation binodal, punctation extends to elytral apex, epipleural margin serrulate near elytral apex. Abdomen: Pygidium scutiform.

Distribution ( Fig. 71 View Fig 71 ): This species is known from Chile.

Etymology: The trivial name, robles, constitutes a noun in apposition and refers to the type locality.

R e m a r k s: The color pattern, on the elytral disc, involving rectangulate elytral fasciae, places this species near Labasiella transversalis (SOLERVICENS). But, the holotype of L. robles lacks knobs on the pronotal disc ( Fig. 50 View Figs 44-56 ), four of which are present in L. transversalis ( Fig. 52 View Figs 44-56 ). Also, in the L. robles specimen there are serrations in the posterior region of the epipleural margin, which is not the case in L. transversalis specimens. Differences in the presence or absence of pronotal knobs and epipleural serrations are good indicators for distinguishing species within Labasiella .
