Definitions For Glossary Terms
- LABIAL PALPUS
- Paired finger-like appendages on the labium
composed of up to three segments. [drawing][photo][drawing]
- LABIOMAXILLARY COMPLEX
- Term for the composite ventromedian labium
and ventrolateral pair of maxillae. [drawing][photo]
- LABIUM
- Unpaired, ventral sclerite of the mouthparts that forms the median portion
of the labiomaxillary complex.
[drawing][photo][drawing]
- LABRUM
- Unpaired, dorsomedian sclerite of the mouthparts that is concealed under or
partly to entirely exposed below the clypeus;
the labrum is usually flap-like but sometimes is deeply emarginate so as to be
digitate, that is, with finger-like projections. [drawing]
- LACINIA
- (pl., laciniae) Inner, apical lobe of the maxilla. [drawing]
- LAMINA/LAMELLA
- A thin plate-like or leaf-like cuticular protrusion.
- LAMINATED BRIDGE
- Transversely striated band of notal
membrane that connects the basally unfused portions of the second valvulae or stylet sheath.
- LANCEOLATE
- Spear shaped, i.e. longer than wide and tapered apically (see also oval/ovate/ovo id and spatulate).
- LATERAL / LATERAD
- At or toward the side of the body or outer edge of a structure. [drawing][drawing]
- LATERAL LOBE OF MESOSCUTUM
See
mesoscutal lateral lobe
- LATERAL OCELLAR LINE
- Minimum distance between the anterior and a posterior ocellus, abbreviated as LOL or LOD. [drawing]
- LATERAL OCELLUS
See posterior ocellus
- LATERAL PANEL OF AXILLA
- Lateral, vertical surface of each axilla.
[drawing][photo][photo]
- LATERAL PANEL OF METANOTUM
- More or less concave region of the metanotum on either side of the dorsellum; sometimes called the 'lateral wings'
of the metanotum.
[drawing][photo]
- LATERAL PANEL OF PRONOTUM
- The more or less vertical, lateral surface of the pronotum below the mesothoracic spiracle. [drawing][photo]
- LATERAL TUBERCLES
See ventral process
- LATERAL WING OF METANOTUM
See
lateral panel of metanotum
- LIGULA
- The apical 'fleshy' and microsetose lobe of the labium, formed from the combined glossae and paraglossae. [drawing][drawing][photo]
- LINEA CALVA
- Narrow, oblique bare band on the forewing disc that is directed from the
posterobasal margin of the wing toward the base of the stigmal vein (see also speculum). [drawing][drawing]
- LINEAR SENSILLA
See longitudinal sensillum
- LOD See lateral ocellar line
- LOL See lateral ocellar line
- LONGITUDINAL SENSILLUM
- (pl., longitudinal sensilla) Ridge-like, longitudinal sensory
structure on some or all of the funicular and claval segments of the flagellum;
sometimes called multiporous plate sensilla, linear sensilla, placoid sensilla,
sensory ridges, or rhinaria. Characteristic of a longitudinal sensillum is that
the apex projects free for varied lengths above the surface and/or beyond the
apex of the respective flagellar segment so that it can look like a seta if the projection is very long, but unlike a
seta it is not articulated and its surface is continuous with the segment. [photo]
- LOWER FACE
- Region of the face below the toruli. [drawing]
- LOWER MESEPIMERON
- Ventral region of the mesepimeron that
is sometimes differentiated from an upper mesepimeron by a transepimeral sulcus. [drawing][photo]
- LOWER MESEPISTERNUM
- Mostly ventral region of the mesepisternum below the transepisternal line/sulcus,
if present, which comprises most of the mesothoracic venter; often termed the mesosternum. [drawing][photo]
