Bioacoustics of Makalapobius

Description. Including characters shared by other Burcini . Burcini of average size. General coloration typical for Burcini , from light grey to light yellowish, with numerous black patterns. Head, pronotum and femora with long black bristles ( Figs. 1–3 ). Head. Not wider than pronotum ( Figs. 1 , 12 ). Antennae dark, unbanded. Eyes moderately protruding, not flattened on head dorsum ( Figs. 1–3 , 12–13 ). Ocelli small; lateral ocelli rounded, well distinct; median ocellus less distinct, localized dorsally to fastigium tip; distance between lateral ocelli larger than distance between one lateral ocellus and median ocellus. Fastigium between antennae not wider that scapes ( Figs. 3 , 13 ); scapes wider than high (front view); palpi short, article length: 5>3>4; article 5 apex strongly widened. Thorax. Pronotum ( Figs. 1–2 , 12 ) wider than long, 0.65–0.70 times as long as wide; DD sides subparallel, DD slightly narrower anteriorly, slightly enlarged before mid-length; DD anterior margin inconspicuously concave; DD posterior margin weakly rounded; DD longitudinal median furrow weakly imprinted; DD anterior transverse furrow distinct on the sides; LL shallow, higher anteriorly, less high posteriorly. Legs. Legs of average size for Burcini , not elongated. TI with long narrowly oval outer tympanum; without inner tympanum. TI and TII with 2 ventral apical spurs, the inner the longest. FIII not particularly widened nor narrow ( Figs. 4 , 14 ): ca. 3.0–3.3 times as long as wide. TIII apical spurs typical of burcini ( Figs. 4–5 ): 3 ao, 2 ai; relative length of apical spurs: ao2>ao3>ao1, ai2>ai1. TIII with 3 outer and 2 inner subapical spurs; relative length of subapical spurs: sao1=sao2>sao3, sai1>sai2. Hind tarsi long, particularly hind basitarsi. Hind basitarsi without dorsal serration (as usual in Nemobiini, see Desutter-Grandcolas et al. accepted); with 3 apical spurs: 2 dorsal apical spurs, the inner very small, 1 inner ventral apical spur longer than the dorsal outer one. Wings. FW ( Figs. 71, 72 ) present in males, absent in females. HW absent in both sexes. Coloration. Head ( Figs. 1–3 , 12–13 ): Face with black patterns below the eyes converging to clypeus; semicircular area below antennae black; face black patterns surrounding a light yellow triangle pointing upwards; mandibles light yellow; scapes light yellow, antennae darker than scapes, not banded; palpi light yellow; genae light yellow; tip of fastigium black dorsally; semicircular area dorsal to antennae with dark pattern; occiput dark yellow. Thorax ( Figs. 1–2 , 12 ): Pronotum color variable, DD light yellow with black lateral spots near anterior margin or very dark with two light lateral spots near anterior margin; LL black, anterior ventral margin light yellow. Abdomen dark with or without light yellow spots. Legs ( Figs. 4–5 , 14 ): yellow or light yellow with darker bandings; FIII lateral side with dark basis, with 3 transverse dark bandings; TIII dark. Male. Wings. FW ( Fig. 1, 7 , 12, 16 ) oval in shape, truncated apically. Stridulatory apparatus well developed, with relatively long diagonal vein; with well distinct chords, relatively long for Burcini ; without a mirror: FW distal part with reticulation ( Fig. 7 ). Subgenital plate. Apex trilobated ( Fig. 6 ), median lobe small, membranous, not longer than lateral lobes. Genitalia ( Figs. 19–24 ). Pseudepiphallus narrow in dorsal view and side view, elongated, lightly curved upwards (sideview); apex with rounded distal lophi; without apical lateral extensions; without large apical concavity visible dorsally. Apodemes absent. Epi-ectophallic invagination not extending more anteriorly than rami insertion. Rami very wide (side view). Female. No trace of wings ( Figs. 18 , 72 ). Subgenital plate ( Fig. 8 ) trapezoidal. Ovipositor weakly up curved; weakly enlarged apically ( Fig. 17 ). Genitalia. Copulatory papilla not examined. Calling song. When known, male call is made of verses of increasing amplitude lasting more than 1 second ( Fig. 9–11 ).
