Zoobank: urn:lsid:zoobank.org:act:BCF6F948-1D2E-4151-9426-E6B3171DF152

( Figs 3A–L ; 5E, F )

Diagnosis: Head ( Fig. 3A, B ) ivory. Clypeus ( Fig. 3B ) expanded apically. Male pygofer ( Fig. 3E ), longer than high, ventral margin with a well-developed subapical tooth; posterior margin acutely rounded. Anal tube ( Fig. 3E, F ) with a pair of long basal processes, crossed with each other, preapical region with secondary narrow lateral projection. Subgenital plates ( Fig. 3H ) subrectangular, slightly wider at median third, abruptly narrowed at apical portion. Aedeagus ( Fig. 3K, L ), with shaft long and thin along entire length, tubular, laterally compressed at apical portion, directed dorsally and curved posteriorly, apex rounded; gonopore subapical on ventral margin.

Measurements. Male, 4.7 mm (n = 1).

Description. Head, in dorsal view ( Fig. 3A ), coronal suture present throughout posterior half of crown. Head, in frontal view ( Fig. 3B ), clypeus approximately 1.6 times higher than maximum width, apical portion expanded. Forewing ( Fig. 3D ) approximately 3.6 times longer than maximum width; basis of second and fourth apical cells approximately equidistant and proximal to base of third apical cell. Other external morphological characters, as the generic description in Marques-Costa & Cavichioli (2007).

Coloration. Ivory ( Figs 3A–C ; 5E, F ). Head and face, except gena ( Figs 3A–C ; 5E, F ) ivory without marks. Pronotum, mesonotum, and forewing ( Figs 3A–D ; 5 E, F ) ivory. Thorax ( Fig. 3B, C ) ventrally dark brown to black. Legs ( Fig. 5E, F ) pale yellow with brown areas.

Male terminalia. Pygofer, in lateral view ( Fig. 3E ), approximately 2.2 times longer than high; dorsal and ventral margins parallel on basal two-thirds, convergent on apical third; ventral margin with a well-developed subapical tooth; posterior margin acutely rounded. Anal tube ( Fig. 3E, F ) with tergite X cylindrical, bearing a pair of elongated and strongly ventrally curved basal processes, crossed one with each other; preapical region of process with secondary elongated and narrow lateral projection, directed outwards and curved dorsally, slightly expanded apically; apex of processes acute. Subgenital plates, in lateral view ( Fig. 3G ), slightly surpassing the pygofer apex; in ventral view ( Fig. 3H ), subrectangular, slightly wider at median third, abruptly narrowed at apical portion; ventral surface with few microsetae on apical portion; apex of each plate rounded. Connective ( Fig. 3I ) approximately one-third length of the styles. Style ( Fig. 3I, J ) elongated; apodeme bilobed, with dorsal projection broadly rounded and ventral projection subtriangular; apophysis with apical portion expanded and curved dorsally, with some robust setae on outer side of preapical lobe and thin setae on ventral surface, under the apical hook; apical hook well-developed, curved ventrally, apex acute. Aedeagus ( Fig. 3K, L ) with preatrium and dorsal apodeme developed; shaft tubular, thin along entire length, directed dorsally and curved posteriorly, apical portion laterally compressed, apex rounded; gonopore subapical on ventral margin.

Female. Unknown.

Distribution. Ecuador (Orellana).

Etymology. From Latin, albus = white and cephalus = head. The name alludes to light-colored head, in contrast to the other species of the genus: N. nigricephala , characterized by black head.

Material examined. Male holotype: “ ECUADOR, Orellana, \ Transect Ent. 1 km S. Onkone \ Gare Camp, Reserva Etnica \ Waorani Onkone Gare Camp , \ 00°39’10”S – 076°26’00”W; \ 220 m; 12.ii.1995; T.L. Erwin \ et al.; T-2; Fogging terre firme \ Forest; Lot #982”, “DNA voucher \ Entomologia DZRJ \ ENT5331 ” ( MEPN) .

Notes. Neocoelindroma albicephala sp. nov. differs from N. nigricephala as follows: 1) head ivory, without macula ( Fig. 3A ), whereas N. nigricephala has a large black apical macula on crown and face completely black (Marques-Costa & Cavichioli 2007; figs 1, 3); 2) basal processes of anal tube with a subapical lateral projection ( Fig. 3E, F ), whereas in N. nigricephala , the basal processes lack projections (Marques-Costa & Cavichioli 2007; figs 5, 10); and 3) aedeagus shorter, shaft with constant width throughout its length, apex rounded, and gonopore subapical ( Fig. 3K, L ), while N. nigricephala has a longer aedeagus with the shaft progressively tapering distally, apex acute, and gonopore apical (Marques-Costa & Cavichioli 2007; fig. 9).
