Description. Female: General coloration of integument brown; dorsal surface darker than ventral; distal portion of head, parts of mandibles, margins of pro- meso- and metathorax, of scutellum, of elytra (suture and epipleura), of ventrite V, and parts of legs from dark-brown to blackish; extreme distal of ventrites slightly darker than remaining surface. Body not flattened dorsoventrally ( Fig. 3 ). Head elongated behind eyes. Width of head plus eyes equal to 0.9 times that of pronotum at anterolateral angles. Length of mandible equal to 0.7 times that of head; moderately coarsely, sparsely punctate on dorsal surface (sometimes, distinctly coarsely, abundantly punctate on basal half near inner edge), slightly finer towards apex; outer surface vertical, triangularly excavated between base and ventral tooth, moderately coarsely, sparsely punctate on basal half, finer and closer on apical half; pilosity very short, sparse on outer and dorsal surface, somewhat longer near inner edge. Dorsal surface of head coarsely, abundantly punctate, slightly finer towards clypeus and coarser laterally between the eyes and prothorax; sulcus between the gibbosities moderately shallow, enlarged toward clypeus. Clypeus medially in the same level as the area of the sulcus between the gibbosities of the head; laterally slightly lower than centrally; moderately coarsely, sparsely punctate (mainly laterally); pilosity very short, sparse. Clypeolabral suture distinct throughout. Median projection of labrum wide, short, rounded at apex; punctures as in clypeus; pilosity very short, moderately longer on centro-apical region. Ocular carina distinct. Largest width of eyes about 0.6 times length; posterior edge of eyes strongly elevated in relation to the area behind it. Area behind eyes c oarsely punctate near apex of upper ocular lobe, gradually sparser, finer towards gula, mainly after apex of lower ocular lobe. Submentum distinctly separated from genae and gula, slightly tumid between gula and anterior third, then distinctly oblique towards anterior edge, somewhat depressed laterally in this region; surface coarsely, moderately sparsely punctate; anterior edge elevated; pilosity short, sparse, with some long hairs in middle area near anterior edge. Antennae not reaching apex of prothorax; antennomere XI 1.7 times longer than X; ventral sensorial area of antennomeres III-X not divided by carinae and not visible from side; XI divided and distinctly visible from side.

Sides of prothorax ( Fig. 1–2 ) nearly parallel or slightly rounded from the area of the middle lateral angles to anterolateral angles, convergent from the former towards posterolateral angles; anterolateral angles projecting forward, acute (not as pronounced and rounded in one female); posterolateral angles acute, projecting; lateral angles absent. Disc of pronotum almost flat centrally, somewhat coarsely punctate centrally, gradually coarser, more abundantly punctate laterally; anterior edge straight, except near anterolateral angles. Metasternum coarsely, abundantly punctate laterally, gradually finer, sparser towards central area. Metepisterna coarsely, abundantly punctate. Elytra abundantly, coarsely, deeply punctate ; dorsal carinae distinct or almost indistinct. Ventrites I–IV finely, sparsely punctate centrally, gradually coarser, more abundant laterally; ventrite V moderately coarsely punctate throughout, mainly laterally; pilosity very short and sparse, longer and more abundant on centro-apical region of V. Metatarsomere I about 1.2 times longer than II–III together ; length of metatarsomere V (without claws) about 0.9 that of I–III together.

Dimensions in mm (female) (3 specimens). Total length (including mandibles), 12.4–16.9; prothorax: length 2.5-3.4; anterior width, 3.1–4.1; posterior width, 2.8–3.8; humeral width, 3.2–4.3; elytral length, 7.7–10.6.

Diagnosis. Females of Malukandra heterostyla differ from females of M. hornabrooki mainly by the sculpture on the dorsal surface of head, between the eyes, formed by coarse and abundant punctures (fine and very sparse in the latter). Females of M. jayawijayana remain unknown, but since males of this species have metatarsomere V slightly longer than I–III together, we believe this is also the case in females. In males and females of M. heterostyla metatarsomere V is shorter than I–III together.

Comments. With the specimens examined in this study, Malukandra heterostyla is currently known from five specimens (two males and three females). At the time of the transfer of Parandra heterostyla to Malukandra , only two males were known. Now we had the opportunity to examine three females that belong to the species. Although we have examined a great number of specimens of Parandrinae from the Oriental Region in recent years, few specimens were from Sulawesi. Thus, it is not possible to exclude the possibility of the occurrence of M. heterostyla on this island, mainly because of the proximity of Halmahera Island.

Material examined. INDONESIA, North Maluku: Halmahera Island (“kao Dist., Camp 34, 34 km inland from Pan-Tunggal Lumber Co.; base camp at Tg. Loleo ”), 3 ♀, 1-14.II.1981, A. C. Messer & P. M. Taylor coll. (2 from USNM; 1 from MZSP) .
