A medium-line, opaque, oil-based paint marker was used to paint a mark on the insect's prothorax
Margin of prothorax
ocher with a white spot dorsally on mesothorax, and a conspicuous black spot dorsally on A4 to A5 abdominal segment.
20,23) They are morphologically similar, with a narrow body, black head, at least two abdominal segments, and the prothorax
and the first 5 abdominal segments are russet coloured (14) (Fig.
Peritrich colonies with a maximum of five or six branches were observed attached to the venter of the extended nasale, on the mouthparts, ventrally at the union of the cranium and prothorax
, and on the seventh abdominal segment.
4) combined with an adult insect prothorax
showed that this internal wood damage was caused by metallic wood borers (Buprestis aurulenta).
Morphometric variables were body length (BL) (from the phastigium to the articulation of the 3rd femur), 3rd femur length (FL), 3rd tibia length (TiL), pronotum length (TxL), prothorax
height (TxH), and tegmen length (TgL).
small, narrow with single row of moderately developed brown-red antepronotal macrosetae.
Head and prothorax
continuously covered by appressed tomentum; prothorax
with a deep, dense and regular punctation.
After 80 h, the black discoloration spread toward the metathorax, mesothorax, prothorax
, and pleural region, and the abdomen was completely compressed and dehydrated.
No macropterous form is known for any of the two species of Paraphrynovelia, and Damgaard (2008b) could not find any convincing morphological characters to diagnose Paraphrynoveliidae, whereas Macroveliidae was diagnosed by the presence of paired, longitudinal ridges of the basal abdominal tergites and two characters also found in Hydrometridae: Eyes distinctly removed from the anterior margin of prothorax
and the dorsally placed metathoracic spiracle.
was characterized by small paired sternites and a notum bearing hair-like sensilla anteriorly and on lateral margins.
Females similar to males, but devoid of secondary sexual characteristics (frontoclypeal horn, pronotal plate and abdominal sex patch) on head, pronotum or abdomen; the prothorax
is narrower at the anterior portion, its anterior edge broadly rounded and anterior angles more obtuse than those of males.
