Genus Borichinda Harbach & Rattanarithikul, 2007
Borichinda cavernicola Rattanarithikul & Harbach, 2007 (in Harbach et al., 2007).
Subfamily Culicinae, tribe Aedini. Borichinda includes a single species, Bc. cavernicola. Genus abbreviation – Bc.
The following salient anatomical differences distinguish Borichinda from Ayurakitia and Isoaedes. ADULTS ‒ Compound eyes narrowly separated; scutum with pattern of dark and pale scaling; scutellum with broad scales on midlobe; postspiracular and subspiracular scales present; remigial setae absent; only one foreungues of males toothed (distinction from Isoaedes); apex of claspette of male genitalia expanded with numerous setae. LARVAE ‒ Seta 4-C short, with 7‒11 branches; seta 14-C branched (distinction from Isoaedes); seta 5-P double; seta 5-T large, stellate, multi-branched; seta 1-I‒VII large, stellate, far anterolateral to seta 1; seta 9-II–VI far anterior to seta 7. PUPAE ‒ Seta 6-III single; seta 6-VII anterior to seta 9; seta 9-IV‒VI anterior to seta 8; apex of paddle slightly concave. See Aedini.
Based on the inclusion of morphological data for Borichinda in the parsimony analysis of Reinert et al. (2004), this genus appears to be more closely related to Isoaedes and Ayurakitia than to other genera of tribe Aedini. The genus appears to have a closer affinity with Isoaedes, which is reflected in the relationships of Fredwardsius, Isoaedes, Borichinda and a clade of other genera, each on a separate branch, recovered in the cladistic analysis of more extensive morphological data by Reinert et al. (2009): Fredwardsius + (Isoaedes + (Borichinda + other genera)). Borichinda was recovered as the sister of Isoaedes in the phylogeny of Wilkerson et al. (2015). In the absence of Isoaedes, it was recovered as the sister of Nyctomyia in the maximum likelihood phylogeny of Soghigian et al. (2017) based on molecular markers.
Borichinda cavernicola is a cave-dwelling species that has only been found and reared from larvae that inhabit a single rimstone pool in Borichinda Cave of Chiangmai Province in northern Thailand. The cave harbours a population of bats that is likely to be the primary source of food for adult females. Nothing else is known about the biology of this species.
Borichinda cavernicola is not a medically or economically importance species.
Borichinda cavernicola is only known from a cave in northern Thailand.
