Diagnosis: This is the only species within the Labasiella complex that has the castaneous elytral disc slightly infuscated at the middle, just anterior the elytral apex.
Redescription: Size: Length 4.0 mm; width 1.5 mm. Form: As in Fig. 73. Integument: Castaneous, except elytral disc with infuscation at middle and just in front of elytral apex. Head: Cranium (Figs 57, 59) coarsely punctate, antennal funicular antennomeres subfiliform (Figs 2, 60), capitulum lax, antennomeres 8 and 9 triangular, antennomere 10 ovate; eyes slightly narrower that width of frons (EW/FW 15/20); last maxillary and labial palpomere securiform. Thorax: Pronotum (Fig. 29) with angular tubercle at sides, disc coarsely punctate, without discal knobs; elytral asetiferous punctures arranged into 10 punctiform striae (Figs 63, 65-68), punctation binodal, punctation extends to elytral apex, epipleural margin serrulate in posterior fourth; legs, ungues as in Fig. 64. Abdomen: Aedeagus (Fig. 97), distal region of phallobase slightly lobed, tegmen very reduced, submembranous, phallobasic struts confluent with phallobasic apodeme, phallobasic rod spatulate, bifid distally; phallic plates broad, phallic apex small triangular. Male Mesodermal Reproductive Organs: Testes comprised of 4 follicles; one pair of accessory glands (Fig. 56). Female Mesodermal Reproductive Organs: Spermathecal capsule slightly sclerotized, spermathecal gland attached to apex of spermatheca; with saccular bursa copulatrix (Fig. 55).
Variation: The available specimens are quite homogeneous.
Natural history: Specimens were collected from February to May; from 5 to 30 m. According to label data, these checkered beetles have been associated with the plant Caesalpinia coriaria (JACQ.) WILLD. ( Fabaceae) and the beetle Xylotheca meieri REITT. ( Anobiidae).
