Visual Description
Anopheles tessellatus is a mosquito species characterized by its distinct morphology. Observations from preserved specimens in the TreeOfLife-200M dataset reveal a slender, elongated body typical of the genus Anopheles. The wings exhibit a patterned appearance, with dark and light scales distributed along the veins, contributing to a "tessellated" or checkered effect, which is a diagnostic feature for the species.[1]
Cytogenetics
The salivary gland chromosomes of Anopheles tessellatus (subgenus Cellia, series Neomyzomyia) have been mapped and described. The chromosomal complement consists of a subtelocentric X chromosome (with a very short arm) and two metacentric autosomes.[2]
Chromosomal Morphology
- X Chromosome: The shortest chromosome (57 µ). It is treated as subtelocentric, with a very short arm (6D) that is sometimes difficult to distinguish or associate clearly with the main body.[2]
- Autosomes: Chromosome 2 has arms of approximately equal length (2R: 178 µ, 2L: 168 µ), and chromosome 3 has arms of unequal length (3R: 225 µ, 3L: 140 µ). In contrast to Anopheles gambiae, where 2R is the longest arm, 3R is the longest arm in A. tessellatus.[2]
- Centromere: Chromosomes are typically joined at the centromere, though the chromocenter is often weak and difficult to locate in preparations.[2]
Cytogenetic Comparisons
A. tessellatus shows no apparent banding pattern homologies with other studied members of the subgenus Cellia (e.g., A. maculatus, A. stephensi, A. pulcherrimus, A. gambiae, A. subpictus). This lack of resemblance is notable, as other Cellia species exhibit significant similarity in their autosomes, particularly at the free ends of the arms.[2]
