Lolodorfus, Bocakova, Milada, 2014

Bocakova, Milada, 2014, Lolodorfus, a new genus of net-winged beetles (Coleoptera: Lycidae: Dexorinae) from Cameroon, Zootaxa 3811 (3), pp. 374-380 : 375-376

Lolodorfus gen. nov.

( Figs. 1–3 )

Type species: Lolodorfus flavus sp. n. (by present designation).

Diagnosis. Lolodorfus gen. nov. differs from Mimolibnetis Pic, 1936 in having 11-segmented antennae while those of Mimolibnetis are 10-segmented. Among other Dexorinae genera, Lolodorfus gen. nov., Mimolibnetis and Lampyrolycus can be easily recognized by elytra presenting 4 longitudinal costae and intercostal intervals with irregular reticulate cells. These genera differ in the length of elytral costa 1, which is fully developed in Lampyrolycus, while medially shortened in Lolodorfus gen. nov. and Mimolibnetis. Dexoris and Elgodexoris have a completely different arrangement of the elytra presenting irregular setiferous tubercles, while reticulate cells and elytral costae are absent.

Description. Eyes large, interocular distance 1.1x wider than eye diameter. Antennae filiform, 11-segmented. Antennomere 1 large, 2 half as long as 1, 3 about 1.4x longer than 2, 4 twice as long as 3 and 1.15 longer than 5, 4 longer than remainder. Antennomeres 4-10 diminishing in length ( Figs. 1, 2 ). Mandibles and labrum reduced, vestigial. Maxillary and labial palpi elongate, apices of terminal palpomeres pointed. Pronotum trapezoidal, strongly widened posteriorly, 1.5x wider basally, anterior margin weakly stretched forwards, lateral margins elevated dorsally, posterior angles acute. Pronotal carinae conspicuously flattened, reduced in pronotal folds forming broadly rhomboidal areola medially ( Fig. 3 ). Discal area of pronotum punctate. Scutellum slightly emarginate distally. Elytra elongate, subparallel-sided, 3x longer than humeral width. Each elytron with 4 longitudinal costae, primary costa 1 absent in distal third. Intercostal intervals with more or less double rows of irregular reticulate cells anteriorly, posterior half of elytra presenting single row of reticulate cells between longitudinal costae. Prosternum narrow, strongly transverse. Legs slender, compressed, trochanters elongate, as long as 1/3 of femur, obliquely attached to femora, tibiae straight. Female unknown.

Etymology. The generic name is masculine and is latinised from the locality, Lolodorf in the Cameroon, where the species was collected.

Distribution. Cameroon.
