Fauna Portal Genus Number: 3758

Length 1.80–3.65 mm. Body 2.7–3.4 times as long as wide, parallel-sided and flattened, feebly shiny; with distinctly seriate hairs on elytra. Winged. Head slightly longer than wide with mouthparts orientated anteriorly; eyes moderately large, coarsely facetted usually with short interfacetal setae; vertex with median stridulatory file. Antennal insertions at front of eyes, very close to clypeus, located laterally and hardly visible from above. Antenna shorter than pronotum, 11-segmented with 3-segmented club. Subantennal grooves well developed, not extending beyond eyes. Mouthparts (Fig. 1) generalised, chewing type; labrum sclerotised and partially fused to clypeus. Pronotum with anterior angles rounded; lateral edge crenulate and dentate.

Prosternum long in front of coxae with finely denticulate anterior margin (Fig. 1); prosternal process broad, parallelsided between coxae, expanded apically; procoxal cavities with narrow slits exposing protrochantin, internally open, externally narrowly open. Meso-metaventral junction with metaventral knob deeply fitting into mesoventral process; mesocoxal cavities closed laterally; trochantins concealed.

Elytra with punctation seriate consisting of 10 primary rows separated by secondary rows of slightly smaller punctures; punctures in rows closer to each other along basal part of elytra and more distantly separated along mid length; epipleuron narrow, complete to apex; alternate intervals often slightly elevated and with longer and closely arranged decumbent hairs. Metacoxae strongly transverse, narrowly separated. Legs long and slender; trochanterofemoral joint strongly oblique; tibiae with paired spurs; tarsi 5-5-5 in female, 5-5-4 in male (Fig. 2); tarsomeres simple.

Abdomen with 5 ventrites; ventrite 1 longest, more than twice as long as ventrite 2, without postcoxal lines; usually with paired lateral pore plates in male. Ovipositor long; styli distinct and terminal; spermatheca long, slender, strongly curved, rounded at apex, with more or less distinct narrowing near point of attachment with sperm duct. Aedeagus not inverted, with articulated parameres dorsal to penis; penis with short anterior struts, narrowly rounded or acute at apex; endophallus with complex sclerites.
