Labasiella varipennis SPINOLA, 1849 ( Figs 10 View Figs 1-27 , 37 View Figs 28-43 , 70 View Fig 70 , 89 View Figs 81-89 , 105)
Labasiella varipennis SPINOLA 1849: 409.
Lectotype: Sex not known. Chile, Gay, 1849. A second label reads: S. Rosa (= Santa Rosa de los Andes) (MNHN). Paralectotype. One specimen. Chile, Santa Rosa de los Andes, Gay, 1849 (MNHN). LACORDAIRE 1857: 489. SCHENKLING 1903: 16 (Pelonium). LESNE 1909: 522 (Pelonium). CORPORAAL 1948: 245 ( Labasiella ); 1950: 284 (Cregya). EKIS (now OPITZ), 1975: 61 (Cregya). SOLERVICENS 1989: 198 ( Labasiella ); 1998: 79 (Exochonotus); 2005a: 51; 2006: 23 (Exochonotus).
Diagnosis: The paralectotype is similar in elytral color to the holotype of L. lata , and L. tucumanensis . Labasiella varipennis differs by being the only species in the genus that has a serrulate condition along the entire length of the epipleural margin. Also, only in this species does the elytral disc show 11 striae of punctures.
Redescription: Size: Length 4.5 mm; width 2.0 mm. Form: As in Fig. 89 View Figs 81-89 . Integument: Cranium and thorax dark castaneous; antenna and mouthparts testaceous, except mandibles brown; legs mostly testaceous, femora infuscated distally; elytra bicolored, black basal half of epipleural margin contiguous with black narrow angular fascia, two small black streaks extend backwards from basal margin, a broad black angular fascia behind elytral middle, remainder of elytral testaceous. Head: Cranium coarsely punctate, antennal funicular antennomeres subfiliform ( Fig. 10 View Figs 1-27 ), capitulum lax, antennomeres 9 and 10 triangular, antennomere 11 ovate; eyes small, frons wide (EW/FW 15/32); last maxillary and labial palpomere subsecuriform. Thorax: Pronotum ( Fig. 37 View Figs 28-43 ) with angular tubercle at sides, disc coarsely punctate, with 6 small knobs; elytral asetiferous punctures arranged into 11 punctiform striae, punctures binodal, punctures extend to elytral apex, entire length of epipleural margin serrulate. Abdomen: Aedeagus ( Fig. 105 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 small triangular.
Distribution ( Fig. 70 View Fig 70 ): In addition to the paralectotype I examined 11 specimens from Chile: Región Coquimbo, 5 miles N of Illapel, 30-XI-1950, Ross & Michelbacher; Región Bío Bío, VIII. Termas de Chilean Road, South Las Trancas , 36°53672S 71°28.811W, 29-XI-2001, 4375', Fred G. Andrews; Región Santiago, Quilicura ,?- XII-1986, collector not noted; El Portezuelo, 7 km N. Santiago, 22-25-X- 1981, 500 m, D. & M. Davis; Santiago, La Cistena ,?- XII-1948. Specimens are deposited in CSCA, FSCA, MLPA, MNHN, RGCG, SDEI, and WOPC.
Notes: According to SOLERVICENS (1998: 79), there are two ̎types̎ of this species in MNHN. He designated one of them as the lectotype and the other paralectotype. The lectotype is without head and prothorax. I did not find the lectotype in MNHN. This redescription of Labasiella varipennis is based on the paralectotype.
