Zaitsev, A. A., 2022, Larval description of Lycoperdina smirnoviorum Gusakov, 2017 (Coleoptera: Endomychidae: Lycoperdininae), Russian Entomological Journal 31 (2), pp. 144-153 : 144-146

Larvae of L. smirnoviorum were collected in Far

East and identified by rearing in the laboratory to adults ( Figs 1–5 ). The specimens were preserved in 70% ethanol or on slides with Faure’s Berlese media and are deposited in Moscow Pedagogical State University, Moscow, Russia ( MPGU) .

Habitus photographs were taken with a Canon EOS 40D camera with a MP-E 65 mm macro lens. All photos were processed using Helicon Focus 7.0 software. Line drawings were made in CorelDRAW 12. The measurements were taken with an ocular-micrometer mounted on a MBS1 (Lomo) stereo microscope.

The following abbreviations were used:

body sclerites: CS — cervicosternum, EP — epipleurite, HY — hypopleurite, EM — epimeron, ES — episternum, FR — frontal sclerite, PR — pronotum, TE — tergite, LT — laterotergite, PS — prosternite, MS — mesosternite, MtS — metasternite, PA — parietal sclerite, Pga — paragular area;

head appendages and their parts: Dma — dorsal mandibular articulation, Vma — ventral mandibular articulation, Mm — mandibular membrane, Mxa — maxillary articulating area, Prxcdo — proxicardo, Dstcdo — disticardo, Stp — stipes, Ma — mala, Pf — palpifer, LA — labium, Mnt — mentum, Pmnt — prementum, Smnt — submentum, Lg — ligula;

endoskeletal structures of the head: Epr — epistomal ridge, Plstr — pleurostomal ridge, Hypstr — hypostomal ridge, Hypstrd — hypostomal rod, Hypbr — hypopharyngeal bracon; Hypsc — hypopharyngeal sclerome, R — hypopharyngeal rod, Tc — transverse curvation, Pstocr — postoccipital ridge, Ca — cardo attachment area, Prap — cardo promotor apodeme, Abdap — mandibular abductor apodeme, Addap — mandibular adductor apodeme, Tb — tentorial bridge, Pta — poste-

other abbreviations: Asp — atrophied spiracle, Sp — spiracle, Sa — sensorial appendage, Ph — pharynx.

Chaetotaxy nomenclature was not provided because only larvae of last-instar were available, whose chaetome is characterized by numerous secondary setae of various size and topology. Still, when discussing labial palps structure, some setae and pores are coded, but only for convenience and not necessary homologous to that of other beetles larvae.
