Leofa (Edmundiana) kumasamba sp. nov.

( Figs. 29–36 )

Generally rust colored with dark brown, ivory, and ochraceous markings. Much of integument with minute fine hairs. Crown rust colored with ivory markings at posterior margin, a dark brown transverse arcuate band anteriorly at point of deepest depression, with ivory and brown markings anterior to transverse band. Crown texture nearly glabrous. Anterior margin of head glabrous. Ocelli on anterior margin of head, slightly dorsad, and about 1x their own diameter from eye. Face black. Frontoclypeus glabrous to irregularly striate or rugose. Clypellus broad, slightly tapering apically. Pronotum short, rust colored, with black on anterior margin, with lateral carina. Wings brachypterous, marked with brown and ivory, with vestigial venation. Legs with numerous extra hairs and fine setae. Protrochanter with several stout setae. Profemur intercalary row with ~6 setae, the basal 3 of which are very long, relatively thick, and sparsely spaced. Protibia formula 3+4.

Male. Pygofer rounded apically, with numerous long, thick setae and with many smaller setae. Pygofer basolateral cleft membranous. Pygofer lobes nearly touching ventrally at apex. Valve large, triangular. Subgenital plates triangular, rounded at apex, with a lateral row of macrosetae and with several other scattered fine setae and macrosetae. Connective V-shaped, with a stout stem and long anterior arms. Style preapical lobe triangular, with several setae. Style apophysis moderately long, thin, sharply pointed, with a small ventral preapical tooth. Aedeagus situated on small quadrate stalk at base, socle large. Shaft of aedeagus recurved, expanded medially in caudal view, apex deeply divided, gonopore on posterior or ventral surface at base of expansion. Segment X broadly sclerotized dorsally and laterally, sharply angled inward medially in caudal view, and weakly triangular ventrally.

Female. Sternite VII rounded apically, with lateral lobes. Pygofer with several thick macrosetae and numerous smaller setae. Ovipositor protruding from pygofer. First and second valvulae similar to L. thompsoni ( Figs. 25–28 ). First valvula dorsal sculpturing slightly submarginal. Gonoplac with several ventral and apical macrosetae and numerous smaller setae.

Material examined. Male holotype: ZAMBIA: Copperbelt Province; Kitwe District; Kumasamba Lodge nr. Kafue River, ~ 5km S Kitwe; S12 54' 20" E28 14' 22.3"; Apr.19-May 1, 2006; wetter Zambezian Miombo forest; J.R. Cryan & J.M. Urban. Female paratype: ZAMBIA: Copperbelt Province; Kalulushi District; Chembe Bird Sanctuary, ~ 6 km E Kalulushi; S12 50' 25" E28 07' 03"; Apr. 19-May 1, 2006; wetter Zambezian Miombo forest; J.M. Urban. Both specimens deposited at INHS. Genomic DNA has been extracted from the thorax and abdomen of the female paratype. The head and prothorax are point mounted and the cleared tissue is stored in glycerin.

Etymology. The species is named for the lodge near its type locality, Kumasamba Lodge. Kumasamba is the Bemba word for “where the sun sets”.

Diagnosis. Easily distinguished from Indian Leofa spp. by the simple aedeagus (without ventral appendage) and from Leofa pedunculata by the form of the aedeagus.
