Petalocephala cephalotes Distant

Petalocephala cephalotes Distant Figs 2E–G. Petalocephala cephalotes Distant 1916: 218. Diagnosis. Female. Crown lateral margins straight for half-length in front of eyes then convergent with broadly rounded apex. Resembling P. kempi but differs in having the crown slightly shorter than interocular distance whereas in the latter the crown is much longer (1.4 ×) than interocular distance. Description. Distant (1916) adequately described the external features of this species. Additional features are as follows. Crown margin yellowish white; median suture not prominent, lateral margins in front of eyes straight for half-length and then convergent, apex broadly rounded; about 0.85× as long medially as interocular distance, about 1.2× as long as median length of pronotum. Pronotum with lateral margins parallel sided. Mesonotum as long as median length of pronotum. Material examined. INDIA: SYNTYPE ♀, “Coonoor, Nilgiri Hills, B.40”, “ Petalocephala cephalotes Dist., type”, “Type”, “ Syntype ” (BMNH). Remarks. Distant (1916) described this species from unspecified number of specimens (syntypic) with the following data: “Nilgiri Hills; Coonoor (T.V. Campbell)”.

Abstract

Petalocephala cephalotes Distant Figs 2E–G. Petalocephala cephalotes Distant 1916: 218. Diagnosis. Female. Crown lateral margins straight for half-length in front of eyes then convergent with broadly rounded apex. Resembling P. kempi but differs in having the crown slightly shorter than interocular distance whereas in the latter the crown is much longer (1.4 ×) than interocular distance. Description. Distant (1916) adequately described the external features of this species. Additional features are as follows. Crown margin yellowish white; median suture not prominent, lateral margins in front of eyes straight for half-length and then convergent, apex broadly rounded; about 0.85× as long medially as interocular distance, about 1.2× as long as median length of pronotum. Pronotum with lateral margins parallel sided. Mesonotum as long as median length of pronotum. Material examined.
