Labasiella lobaticollis ( LESNE, 1909) ( Figs 5 View Figs 1-27 , 32 View Figs 28-43 , 70 View Fig 70 , 84 View Figs 81-89 )
Pelonium lobaticolle LESNE 1909: 521.
Lectotype: ♀. PÉROU, Paita et Tallazo de Paita (Reg. Desetique, bord de la mer) (30-80 m d' alt), P. Rivet, 1906. (MNHN). Lesne did not specify in his description whether his nominal species is based on more than one specimen. Therefore, I invoke Recommendation 73F of the ICZN (1999) and designate a lectotype for this nominal species. CORPORAAL 1950: 288 (Pelonium). SOLERVICENS 1998: 79 (Exochonotus); 2004: 31 (Exochonotus) 2006: 23 (Exochonotus) .
Diagnosis: The holotype of this species resembles superficially the holotype of L. machupicchu , from which it is distinguished by elytral punctation. The punctures are larger and the interstitial spaces smaller. In the available specimen of L. lobaticollis the interstitial spaces are narrower than the width of the punctures. The opposite is true in the holotype of L. machupicchu . Also, in L. machupicchu specimens the funicular antennomeres are bicolorous, which is not the case in L. lobaticollis specimens.
Redescription: Size: Length 3.5 mm; width 1.3 mm. Form: As in Fig. 84 View Figs 81-89 . Integument: Cranium and thorax dark castaneous, pronotum midline broadly light castaneous; antenna testaceous; mouthparts testaceous, mandibles brown; legs mostly testaceous, femora infuscated distally; pterothorax brown; elytra mostly testaceous, basal margin, basal half of epipleural margin, and 2 angular fascia brown, posterior fascia broader than more anterior fascia, 2 short lines just behind anterior margin. Head: Cranium coarsely punctate, antennal funicular antennomeres subfiliform ( Fig. 5 View Figs 1-27 ), capitulum lax, antennomeres 9 and 10 triangular, antennomere 11 globose; eyes small, frons wide (EW/FW 10/27); last maxillary and labial palpomere subsecuriform. Thorax: Pronotum ( Fig. 32 View Figs 28-43 ) with angular tubercle at sides, disc coarsely punctate, with 4 small knobs; elytral asetiferous punctation arranged into 10 punctiform striae, punctation binodal, punctation extends to elytral apex, epipleural margin serrulate near elytral apex. Abdomen: Pygidium scutiform.
Distribution ( Fig. 70 View Fig 70 ): This species is known from Peru.
