Genus Cleopomiarus Pierce, 1919

Description.

Measurements (in mm). Body length: 2.20-8.70. Body width (metathorax or abdominal segments I–II) 0.73-2.44. Head width: 0.35-1.16.

General. Body elongated, slender, rounded in cross section.

Colouration. From yellow to pale brown head. All thoracic and abdominal segments from distinctly white to slightly yellow.

Vestiture. Setae on body thin, in different colouration, distinctly different in length; piliform, often with some asperities.

Head capsule. Head oval or suboval, slightly or more flattened laterally, endocarinal line present and very distinct, more than half the length of frons. Frontal sutures on the head in different sizes, and ever extended to antennae. One or two stemmata (st), anterior stemma in the form of a pigmented spot with convex cornea behind the antenna. Dorsum of the epicranium with five setae; des3 located anteriorly on epicranium close border with frontal suture. Frons with four setae; fs2 absent; fs4; and fs5 subequal. Head also with two les and two ves. Epicranial area with three pes and 2-3 sensilla.

Antennae located at the end of the frontal suture on each side, membranous and distinctly convex basal article bearing 3-4 sensilla and one conical sensorium, the later elongated, narrow.

Clypeus transverse-shaped, approximately 2.5-3 times as wide as long with two cls, and one sensillum (clss) between setae; all very close to margin with frons.

Mouthparts. Labrum with three piliform lms; anterior margin bisinuate. Epipharynx with three finger-like als; with 2-3 ams; and 0-1 mes; labral rods (lr) distinct, elongated. Mandibles distinctly broad, bifid, teeth of unequal height; slightly truncate; both setae piliform. Maxilla stipes with one stps, two pfs and one mbs and one sensillum; mala with six finger-like dms; five vms; all vms distinctly shorter than dms. Maxillary palpi with two palpomeres; basal palpomere with one short mxps and two sensilla; distal palpomere with one sensillum and a group of micro cuticular apical processes. Prelabium oval-shaped, with one prms; ligula with sinuate margin and 1-2 ligs; premental sclerite well sclerotized but without anterior and posterior extensions, U-shaped. Labial palpi with two palpomeres (partially appears as one palpomere); each of the palpomeres with one sensillum, distal palpomere with cuticular apical processes. Postlabium with three pms, all located laterally.

Thorax. Prothorax slightly smaller than meso- and metathorax. Spiracle bicameral, placed between the pro- and mesothorax (see, e.g., Skuhrovec et al. 2015). Prothorax with 9-10 prns; two ps; and one eus. Mesothorax with one prs, three pds; one as; two long and one short ss; one eps; one ps; and one eus. Chaetotaxy of metathorax almost identical to that of mesothorax. Each pedal area of thoracic segments well separated, with 5-6 pda.

Abdomen. Abdominal segments I–III of almost equal length, next abdominal segments decreasing gradually to the terminal parts of the body. Abdominal segment X reduced to four anal lobes of unequal size, the lateral lobes being distinctly the largest, the dorsal and the ventral lobes being very small. Anus located terminally. Eight spiracles, bicameral, all spiracles functional, close to the anterior margin. Abdominal segments I–VII with one prs; three pds, pds2 the longest one; one long and one minute ss; two long eps; one ps; one lsts; and two eus. Abdominal segment VIII with one prs; 2-3 pds, if there are three setae, then pds2 the longest one; one long and one minute ss; two long eps; one ps; one lsts; and two eus. Abdominal segment IX with four ds; 1-2 ps; and 1-2 sts. Abdominal segment X with one minute seta present or absent.
