Balaninus analis Marshall 1919: 387

Type material: Lectotype 1 male (present designation) “Puak, / Sarawak / G. E. Bryant / 30.v.14” and “ Balaninus / analis Mshl. / COTYPE” and LECTOTYPE “ Curculio analis (Marshall) des. Pelsue 2009 ” ( BMNH) .

Syntypes: 4 males ”Kuching. / J. E. A. Lewis. / 1910-116.”

1 female “ Type / (BM red-rimmed type disc)” and “Kuching. / J.E.A. Lewis. / 1910-116.” and “ J.E.A.Lewis. / 1910-116.” and “ Balaninus / analis / Mshl / Type female”

8 females “Kuching. / J.E.A.Lewis. / 1910-116.”

4 females “Kuching / 11.5.09, and “Kuching. / J.E.A.Lewis. / 1910-116.”

Diagnosis: Male 4.0– 5.3 mm long; piceous except for legs which are fuscorufous; rostrum more than half the body length in male, but longer than body in female, gradually emerging from frons, evenly deflexed from base to apex; pronotum with anterior basolateral macula with arms reaching past dorsal margin of eye in lateral view and just visible in dorsal view, consisting of tightly packed recumbent, clavate, cretaceous scales; basal margin of pronotum with lateral macula of similar scales and in dorsal view line up with basal fascia on elytra forming V with piceous scutellum set in middle of V. Mesoventral intercoxal process prominent. Elytra with submedian fascia of recumbent, clavate, cretaceous scales and distal vittae of cretaceous scales at apex on interval 1 along margin of crosshatch seta-like scales; venter clothed with decumbent, clavate, cretaceous scales with 2 pronounced tufts of seta-like cretaceous scales on apex of ventrite 5 with apical margin emarginated; metafemur exceeding apex of elytra, with medium tooth; mesofemur with basal margin of long white seta-like scales appearing like fringe of hair.

Differential diagnosis: This species can be confused with Curculio deceptor (Marshall) , C. interruptus (Kirsch) and C. imitator due to the very similar fascia extending from the base of the pronotum to the base of the elytra forming a white V on a black background. It can be distinguished from C. deceptor by ventrite 5 having a pair of large tufts of hair on the apex and the second funicular antennomere as long as the first and appears less robust across the elytral humeri; mesofemur has a basal fringe of long setae forming a beard; basal macular median margin reaching interval 4, whereas in C. deceptor this reaches interval 5 of the elytra. It can be distinguished from C. interruptus by the vestiture of the scutellum which is black in analis and clothed with white scales in interruptus . With C. imitator the size is smaller, the anterior basilateral macular arm reaches only to the middle of the eye and is not visible in dorsal view, metafemur reaches apex of elytra or only slightly exceeds it; the basal pronotal macular median margin reaches to elytral interval 4 on both male and female; the mesofemur lacks the basal fringe of long setae-like hair that is present in C. analis males.

Distribution: This species is only known from Malaysian Borneo: Sarawak, Sabah, Kuching, and Puak.
